+# Repository Guidelines
+Comprehensive directory map for everything under `src/` so agents and contributors can navigate confidently.
+
+## Legend & Scope
+Lines reference paths relative to `/home/vasceannie/repos/biz-budz`.
+`__pycache__/` folders exist in most packages and are excluded from detail.
+`.backup` files capture older implementations—consult primary modules first.
+
+## Root: src/

-# Business Buddy Agent Design & Implementation Guide
-
-This document provides standards, best practices, and architectural patterns for creating and managing **agents** in the `biz_bud/agents/` directory. Agents are the orchestrators of the Business Buddy system, coordinating language models, tools, and workflow graphs to deliver advanced business intelligence and automation.
-
-## Available Agents
-
-### Buddy Orchestrator Agent
-**Status**: NEW - Primary Abstraction Layer
-**File**: `buddy_agent.py`
-**Purpose**: The intelligent graph orchestrator that serves as the primary abstraction layer across the Business Buddy system.
-
-Buddy analyzes complex requests, creates execution plans using the planner, dynamically executes graphs, and adapts based on intermediate results. It provides a flexible orchestration layer that can handle any type of business intelligence task.
-
-**Design Philosophy**: Buddy wraps existing Business Buddy nodes and graphs as tools rather than recreating functionality. This ensures consistency and reuses well-tested components while providing a flexible orchestration layer.
-
-### Research Agent
-**File**: `research_agent.py`
-**Purpose**: Specialized for comprehensive business research and market intelligence gathering.
-
-### RAG Agent
-**File**: `rag_agent.py`
-**Purpose**: Optimized for document processing and retrieval-augmented generation workflows.
-
-### Paperless NGX Agent
-**File**: `ngx_agent.py`
-**Purpose**: Integration with Paperless NGX for document management and processing.
-
----
-
-## 1. What is an Agent?
-
-An **agent** is a high-level orchestrator that uses a language model (LLM) to reason about which tools to call, in what order, and how to manage multi-step workflows. Agents encapsulate complex business logic, memory, and tool integration, enabling dynamic, adaptive, and stateful execution.
-
-**Key characteristics:**
-- LLM-driven reasoning and decision-making
-- Tool orchestration and multi-step workflows
-- Typed state management for context and memory
-- Error handling and recovery
-- Streaming and real-time updates
-- Human-in-the-loop support
-
----
-
-## 2. Agent Architecture & Patterns
-
-All agents follow a consistent architectural pattern:
-
-1. **State Management**: TypedDict-based state objects for workflow coordination (see [`biz_bud/states/`](../states/)).
-2. **Tool Integration**: Specialized tools for domain-specific tasks, with well-defined input/output schemas.
-3. **ReAct Pattern**: Iterative cycles of reasoning (LLM) and acting (tool execution).
-4. **Error Handling**: Comprehensive error recovery, retries, and escalation.
-5. **Streaming Support**: Real-time progress updates and result streaming.
-6. **Configuration**: Flexible, validated configuration for different use cases.
-
-### Example: Agent Execution Patterns
-
-**Synchronous Execution:**
-```python
-from biz_bud.agents import run_research_agent
-
-result = run_research_agent(
-    query="Analyze the electric vehicle market trends",
-    config=research_config
-)
-analysis = result["final_analysis"]
-sources = result["research_sources"]
-```
-
-**Asynchronous Execution:**
-```python
-from biz_bud.agents import create_research_react_agent
-
-agent = create_research_react_agent(config)
-result = await agent.ainvoke({
-    "query": "Market analysis for renewable energy",
-    "depth": "comprehensive"
-})
-```
-
-**Streaming Execution:**
-```python
-from biz_bud.agents import stream_research_agent
-
-async for update in stream_research_agent(query, config):
-    print(f"Progress: {update['status']}")
-    if update.get('intermediate_result'):
-        print(f"Found: {update['intermediate_result']}")
-```
-
----
-
-## 3. State Management
-
-Agents use specialized state objects (TypedDicts) to coordinate workflows, maintain memory, and track progress. See [`biz_bud/states/`](../states/) for definitions.
-
-**Examples:**
-- `ResearchAgentState`: For research workflows (query, sources, results, synthesis)
-- `RAGAgentState`: For document processing (documents, embeddings, retrieval results, etc.)
-
-**Best Practices:**
-- Always use TypedDicts for state; document required and optional fields.
-- Use `messages` to track conversation and tool calls.
-- Store configuration, errors, and run metadata in state.
-- Design state for serialization and checkpointing.
-
----
-
-## 4. Tool Integration
-
-Agents integrate with specialized tools (see [`biz_bud/nodes/`](../nodes/)) for research, analysis, extraction, and more. Each tool must:
-- Have a well-defined input/output schema (Pydantic `BaseModel` or TypedDict)
-- Be registered with the agent for LLM tool-calling
-- Support async execution and error handling
-
-**Example: Registering a Tool**
-```python
-from biz_bud.agents.research_agent import ResearchGraphTool
-from biz_bud.services.factory import ServiceFactory
-
-research_tool = ResearchGraphTool(config, ServiceFactory(config))
-llm_with_tools = llm.bind_tools([research_tool])
-```
-
----
-
-## 5. The ReAct Pattern
-
-Agents implement the **ReAct** (Reasoning + Acting) pattern:
-1. **Reasoning**: The LLM receives the current state and decides what to do next (e.g., call a tool, answer, ask for clarification).
-2. **Acting**: If a tool call is needed, the agent executes the tool and appends a `ToolMessage` to the state.
-3. **Iteration**: The process repeats, with the LLM consuming the updated state and tool outputs.
-
-**Example: ReAct Cycle**
-```python
-# Pseudocode for agent node
-async def agent_node(state):
-    messages = [system_prompt] + state["messages"]
-    response = await llm_with_tools.ainvoke(messages)
-    tool_calls = getattr(response, "tool_calls", [])
-    return {"messages": [response], "pending_tool_calls": tool_calls}
-```
-
----
-
-## 6. Orchestration with LangGraph
-
-Agents are implemented as **LangGraph** state machines, enabling:
-- Fine-grained control over workflow steps
-- Conditional routing and error handling
-- Streaming and checkpointing
-- Modular composition of nodes and subgraphs
-
-**Example: StateGraph Construction**
-```python
-from langgraph.graph import StateGraph
-
-builder = StateGraph(ResearchAgentState)
-builder.add_node("agent", agent_node)
-builder.add_node("tools", tool_node)
-builder.set_entry_point("agent")
-builder.add_conditional_edges(
-    "agent",
-    should_continue,
-    {"tools": "tools", "END": "END"},
-)
-builder.add_edge("tools", "agent")
-agent = builder.compile()
-```
-
----
-
-## 7. Error Handling & Quality Assurance
-
-Agents must implement robust error handling:
-- Input validation and sanitization
-- Tool and LLM error detection, retries, and fallback
-- Output validation and fact-checking
-- Logging and monitoring
-- Human-in-the-loop escalation for critical failures
-
-**Example: Error Handling Node**
-```python
-from biz_bud.nodes.core.error import handle_graph_error
-
-# Add error node to graph
-builder.add_node("error", handle_graph_error)
-builder.add_edge("error", "END")
-```
-
----
-
-## 8. Streaming & Real-Time Updates
-
-Agents support streaming execution for real-time progress and results:
-- Use async generators to yield updates
-- Stream tool outputs and intermediate results
-- Support for token-level streaming from LLMs (if available)
-
-**Example: Streaming Agent Execution**
-```python
-async for event in agent.astream(initial_state):
-    print(event)
-```
-
----
-
-## 9. Configuration & Integration
-
-Agents are fully integrated with the Business Buddy configuration, service, and state management systems:
-- Use `AppConfig` for all runtime parameters (see [`biz_bud/config/`](../config/))
-- Access services via `ServiceFactory` for LLMs, databases, vector stores, etc.
-- Compose with nodes and graphs from [`biz_bud/nodes/`](../nodes/) and [`biz_bud/graphs/`](../graphs/)
-- Leverage prompt templates from [`biz_bud/prompts/`](../prompts/)
-
----
-
-## 10. HumanMessage, AIMessage, and ToolMessage Usage
-
-- **HumanMessage**: Represents user input (`role="user"`). Always the starting point of a conversation turn.
-- **AIMessage**: Represents the assistant’s response (`role="assistant"`). May include tool calls or direct answers.
-- **ToolMessage**: Represents the output of a tool invocation (`role="tool"`). Appended after tool execution for LLM consumption.
-
-**Example: Message Flow**
-```python
-state["messages"] = [
-    HumanMessage(content="What are the latest trends in AI?"),
-    AIMessage(content="Let me research that...", tool_calls=[...]),
-    ToolMessage(content="Search results...", tool_call_id="..."),
-    AIMessage(content="Here is a summary of the latest trends...")
-]
-```
-
----
-
-## 11. Example: Comprehensive Research Agent
-
-```python
-from biz_bud.agents import run_research_agent
-from biz_bud.config import load_config
-
-config = load_config()
-research_result = run_research_agent(
-    query="Analyze the competitive landscape for cloud computing services",
-    config=config,
-    depth="comprehensive",
-    include_financial_data=True,
-    focus_areas=["market_share", "pricing", "technology_trends"]
-)
-
-market_analysis = research_result["final_analysis"]
-competitor_profiles = research_result["competitive_data"]
-trend_analysis = research_result["market_trends"]
-data_sources = research_result["research_sources"]
-```
-
----
-
-## 12. Buddy Agent: The Primary Orchestrator
-
-**Buddy** is the intelligent graph orchestrator that serves as the primary abstraction layer for the entire Business Buddy system. Unlike other agents that focus on specific domains, Buddy orchestrates complex workflows by:
-
-1. **Dynamic Planning**: Uses the planner graph as a tool to generate execution plans
-2. **Adaptive Execution**: Executes graphs step-by-step with the ability to modify plans based on intermediate results
-3. **Parallel Processing**: Identifies and executes independent steps concurrently
-4. **Error Recovery**: Re-plans when steps fail instead of just retrying
-5. **Context Enrichment**: Passes accumulated context between graph executions
-6. **Learning**: Tracks execution patterns for future optimization
-
-### Buddy Architecture
-
-```python
-from biz_bud.agents import run_buddy_agent
-
-# Buddy analyzes the request and orchestrates multiple graphs
-result = await run_buddy_agent(
-    query="Research Tesla's market position and analyze their financial performance",
-    config=config
-)
-
-# Buddy might:
-# 1. Use PlannerTool to create an execution plan
-# 2. Execute the research graph for market data
-# 3. Analyze intermediate results
-# 4. Execute a financial analysis graph
-# 5. Synthesize results from both executions
-```
-
-### Key Tools Used by Buddy
-
-Buddy wraps existing Business Buddy nodes and graphs as tools rather than recreating functionality:
-
-- **PlannerTool**: Wraps the planner graph to generate execution plans
-- **GraphExecutorTool**: Discovers and executes available graphs dynamically
-- **SynthesisTool**: Wraps the existing synthesis node from research workflow
-- **AnalysisPlanningTool**: Wraps the analysis planning node for strategy generation
-- **DataAnalysisTool**: Wraps data preparation and analysis nodes
-- **InterpretationTool**: Wraps the interpretation node for insight generation
-- **PlanModifierTool**: Modifies plans based on intermediate results
-
-### When to Use Buddy
-
-Use Buddy when you need:
-- Complex multi-step workflows that require coordination
-- Dynamic adaptation based on intermediate results
-- Parallel execution of independent tasks
-- Sophisticated error handling with re-planning
-- A single entry point for diverse requests
-
-## 13. Checklist for Agent Authors

+# Directory Guide: src/biz_bud/agents
+
+## Mission Statement
+- This package defines the Business Buddy orchestration agent and its supporting routing, state, and execution utilities.
+- Code here stitches LangGraph nodes, capability discovery, and workflow helpers into a cohesive assistant that powers graphs across the repo.
+- Use this directory when you need to run the full Buddy agent, introspect its behavior, or extend its routing logic.
+
+## Key Artifacts
+- `buddy_agent.py` — builds, configures, and exports the compiled LangGraph that powers the agent.
+- `buddy_nodes_registry.py` — houses the orchestrator, executor, analyzer, synthesizer, and capability discovery nodes with all supporting logic.
+- `buddy_routing.py` — contains routing primitives and default edge maps for Buddy control flow.
+- `buddy_state_manager.py` — provides builder utilities and state inspection helpers for `BuddyState`.
+- `buddy_execution.py` — re-exports workflow execution factories to avoid duplication.
+
+## buddy_agent.py Overview
+- `create_buddy_orchestrator_graph(config: AppConfig | None=None) -> CompiledGraph` wires nodes into a `StateGraph` and compiles the agent core.
+- `create_buddy_orchestrator_agent(config: AppConfig | None=None, service_factory: ServiceFactory | None=None) -> CompiledGraph` loads config, instantiates the graph, and logs outcomes.
+- `get_buddy_agent(config: AppConfig | None=None, service_factory: ServiceFactory | None=None) -> CompiledGraph` caches the default graph for reuse unless custom settings are supplied.
+- `async run_buddy_agent(query: str, config: AppConfig | None=None, thread_id: str | None=None) -> str` executes the graph to completion and returns the synthesized answer.
+- `async stream_buddy_agent(query: str, config: AppConfig | None=None, thread_id: str | None=None) -> AsyncGenerator[str, None]` yields streaming updates for responsive clients.
+- `buddy_agent_factory(config: RunnableConfig) -> CompiledGraph` and `async buddy_agent_factory_async(config: RunnableConfig) -> CompiledGraph` expose factories for LangGraph APIs and Studio integrations.
+- `main()` CLI entrypoint lets maintainers smoke test the agent (`python -m biz_bud.agents.buddy_agent --query "..."`).
+- Module exports `BuddyState` for convenience so downstream code can import state schemas from the agent package.
+
+## buddy_nodes_registry.py Breakdown
+- Maintains regex pattern lists (`SIMPLE_PATTERNS`, `COMPLEX_PATTERNS`) that classify user questions before plan generation.
+- `_format_introspection_response(capability_map, capability_summary)` structures capability metadata for introspection replies and UI surfaces.
+- `_analyze_query_complexity(state, query)` attaches complexity tags and measurement telemetry to state for analytics and routing decisions.
+- `async buddy_orchestrator_node(state, config)` decides when to plan, adapt, or complete; it refreshes capabilities when timeouts expire.
+- `async buddy_executor_node(state, config)` runs plan steps sequentially, converts tool outputs via `IntermediateResultsConverter`, and appends execution history.
+- `async buddy_analyzer_node(state, config)` evaluates plan success, toggles `needs_adaptation`, and seeds reasons for re-planning.
+- `async buddy_synthesizer_node(state, config)` compiles intermediate findings, attaches citations, and formats final responses with `ResponseFormatter`.
+- `async buddy_capability_discovery_node(state, config)` scans service registries to keep capability listings live for introspection commands.
+- Each node leverages decorators from `biz_bud.core.langgraph` (`standard_node`, `handle_errors`, `ensure_immutable_node`) to guarantee logging and error semantics.
+- State mutation occurs via `StateUpdater` wrappers, ensuring only declared keys change; follow this pattern when adding nodes.
+
+## buddy_routing.py Summary
+- `RoutingRule.evaluate(state)` allows conditions expressed as callables or string expressions; string expressions go through `_evaluate_string_condition` for safety.
+- `BuddyRouter.add_rule(source, condition, target, priority=0, description="") -> None` adds prioritized edges and textual descriptions for telemetry.
+- Use `BuddyRouter.set_default(source, target)` to define fallback transitions when no rule matches.
+- `BuddyRouter.route(source, state) -> str` returns the next node or raises `ValidationError` if no path fits; always wrap calls in error handling when experimenting.
+- `BuddyRouter.get_command_router()` exposes a function mapping command objects to targets, integrating with command-based edges.
+- `BuddyRouter.create_routing_function(source)` returns a LangGraph-compatible callable used in `StateGraph.add_conditional_edges`.
+- `BuddyRouter.create_default_buddy_router()` constructs the baseline edge map; update this routine when changing orchestration phases.
+- `BuddyRouter.get_edge_map(source)` is handy for debugging flows and documenting transitions in monitoring dashboards.
+
+## buddy_state_manager.py Summary
+- `BuddyStateBuilder` centralizes state construction with fluent setters for query, thread ID, configuration, context, and orchestration phase.
+- `build()` ensures thread IDs exist, populates default lists (`execution_history`, `selected_tools`), and converts configs into dictionaries for serialization.
+- `StateHelper.extract_user_query(state)` inspects `user_query`, `messages`, and `context` in order of preference to recover the latest question.
+- `StateHelper.get_or_create_thread_id(thread_id=None, prefix="buddy") -> str` standardizes thread naming for logging and analytics.
+- `StateHelper.has_execution_plan(state)` guards executor logic from running when no plan exists.
+- `StateHelper.get_uncompleted_steps(state)` returns a list of plan entries without `completed` markers for progress dashboards.
+- `StateHelper.get_next_executable_step(state)` identifies the next runnable step after filtering completed dependencies.
+- Helpers rely on `HumanMessage` from LangChain; ensure messages appended to state maintain that type to keep extraction accurate.
+
+## buddy_execution.py Summary
+- Re-exports `ExecutionRecordFactory`, `PlanParser`, `IntermediateResultsConverter`, and `ResponseFormatter` from workflow capability packages.
+- Use these re-exports to maintain compatibility with older imports; new code should prefer importing from `biz_bud.tools.capabilities.workflow`.
+
+## Data Flow Primer
+- User input arrives in `BuddyState.messages` and `BuddyState.user_query`; orchestrator duplicates critical information into `initial_input`.
+- Planner and tool nodes populate `execution_plan`, `execution_history`, and `intermediate_results`—structures consumed by executor, analyzer, and synthesizer respectively.
+- Capability discovery updates `available_capabilities` and `tool_selection_reasoning`, enriching introspection replies and plan heuristics.
+- Synthesizer compiles `extracted_info` and `sources`, feeding `ResponseFormatter` to produce human-readable outputs with citations.
+- When adaptation triggers, orchestrator resets `current_step` and increments `adaptation_count` before re-entering planning loops.
+
+## Extensibility Guidelines
+- Extend orchestration by registering new nodes in `create_buddy_orchestrator_graph` and mapping edges through `BuddyRouter`.
+- Introduce new plan step types by adding serialization support to `ExecutionRecordFactory` and parsing logic to `PlanParser`.
+- Update `BuddyState` schema in `states/buddy.py` before reading or writing new fields from nodes; keep builder defaults in sync.
+- When adding capability categories, update `INTROSPECTION_KEYWORDS` and capability summary formatting so introspection answers remain accurate.
+- Wrap new nodes with `standard_node` and `handle_errors` to inherit logging, metrics, and retry semantics.
+- Use `StateHelper` functions instead of raw dictionary mutation to avoid missing optional keys or breaking invariants.
+- Document every new routing rule with a description to help future agents understand why transitions occur.
+- Keep logging high signal; use `logger.debug` for verbose data, `logger.info` for lifecycle events, and `logger.warning` for recoverable anomalies.
+
+## Execution Patterns Worth Knowing
+- Capability refreshes are throttled by `CAPABILITY_REFRESH_INTERVAL_SECONDS` (default 300s); adjust carefully to balance freshness with performance.
+- `_analyze_query_complexity` caches decisions alongside timestamps to avoid redundant classification within a single conversation cycle.
+- Executor uses `extract_text_from_multimodal_content` to flatten attachments; extend that helper when onboarding new file types.
+- Analyzer inspects `state.execution_history` for failure markers and updates `state.last_error` for downstream synthesis logic.
+- Synthesizer merges intermediate facts into `ResponseFormatter` which returns structured sections (`summary`, `key_points`, `next_steps`).
+- Streaming behavior depends on compiled graph support; maintain compatibility when customizing nodes to avoid breaking streaming clients.
+- Singleton cache `_buddy_agent_instance` reduces compile time; bypass by passing custom config when per-request variations are required.
+- Buddy agent expects service factory singletons to be available; ensure `biz_bud.services.factory.get_global_factory` is initialized during app startup.
+
+## Testing Checklist
+- Use `BuddyStateBuilder` to create reproducible state fixtures for node tests.
+- Mock `ExecutionRecordFactory` when verifying executor logic to isolate tool behavior.
+- Validate routing changes by calling `BuddyRouter.route` with representative states and asserting the returned node names.
+- Add regression tests for new regex patterns to prevent misclassification of user queries.
+- Integration tests should invoke `run_buddy_agent` and `stream_buddy_agent` to confirm streaming parity and final response consistency.
+
+## Coding Agent Tips
+- Prefer state builder and helper methods over direct dictionary assignments to maintain invariants.
+- When introducing metrics, log company-specific identifiers (thread ID, plan ID) so data can be aggregated across runs.
+- Keep adaptation counts low by verifying plan quality; repeated adaptations indicate missing capabilities or routing gaps.
+- Document any custom query classifiers added to `SIMPLE_PATTERNS`/`COMPLEX_PATTERNS` so maintainers understand classification behavior.
+- Provide user-facing explanations for adaptation actions in `state.adaptation_reason`; they appear in final summaries.
+- Use asynchronous context managers or `asyncio.gather` carefully; state updates should remain deterministic per node call.
+- Keep CLI entrypoints synchronized with public APIs; they serve as living documentation for how to invoke the agent programmatically.
+- Guard state fields against `None` by using `.get()` or helper functions; plan execution assumes lists and dicts exist.
+
+## Operational Guidance
+- Enable debug logging in `buddy_nodes_registry` during incident response to observe plan generation and routing choices in real time.
+- Monitor capability refresh logs to ensure new tools register correctly; missing logs often mean registration hooks failed.
+- Use `buddy_agent_factory_async` in web servers to avoid blocking the event loop when compiling graphs on demand.
+- For backfills or offline analyses, call `run_buddy_agent` synchronously in batches and persist `execution_history` for auditing.
+- Keep docstrings accurate; documentation generators depend on them to populate contributor guides and agent context.
+
+- Orchestrator updates `state.parallel_execution_enabled`; check this flag before scheduling concurrent steps.
+- Executor populates `state.completed_step_ids`; dashboards can use this list to highlight progress visually.
+- Analyzer consults `state.query_complexity`; ensure complexity scoring remains bounded to avoid over-triggering adaptations.
+- Synthesizer uses `state.tool_selection_reasoning` when explaining chosen capabilities to end users.
+- Capability discovery writes summaries to `state.intermediate_results["capabilities"]`; reuse that data when building admin UIs.
+- `_analyze_query_complexity` logs execution time with `logger.debug`; monitor it if classification becomes a bottleneck.
+- `BuddyRouter.route` respects rule priority order; set higher priority numbers for rarer, more specific conditions.
+- String-based routing rules support Python expressions referencing state keys; sanitize inputs to avoid injection risks.
+- `BuddyStateBuilder.with_context` accepts arbitrary dictionaries; ensure values are JSON serializable for logging and persistence.
+- `StateHelper.get_next_executable_step` returns `None` when dependencies remain; handle this case to avoid busy loops.
+- Streaming generator yields structured objects; preserve this contract for SSE and WebSocket clients.
+- Capability keywords include multilingual phrases; extend them when supporting new locales.
+- Plan parser ensures each step has `id`, `description`, and `tool`; maintain these keys for compatibility with executor displays.
+- Execution history stores timestamps; leverage them to calculate latency per step and identify slow tools.
+- Analyzer increments `state.adaptation_count`; use this metric to trigger alerts when adaptation spikes occur.
+- Synthesizer can bypass plan output when `state.is_capability_introspection` is true; ensure introspection responses stay concise.
+- CLI fallback logs highlighted messages using `info_highlight`; keep colorized output for readability during local debugging.
+- `BuddyRouter.create_default_buddy_router` calls `add_rule` with descriptions; keep them informative for trace logs.
+- State helper `extract_user_query` trims whitespace; pass sanitized strings into downstream prompts.
+- `StateHelper.has_execution_plan` checks the plan object and its `steps` array; ensure plan creation nodes populate both.
+- Capability discovery throttling relies on `time.monotonic()`; use deterministic test doubles to simulate passage of time.
+- Node decorators call `ensure_immutable_node` to guard against accidental mutation; avoid bypassing this decorator stack.
+- When customizing streaming, always return asynchronous generators; synchronous yields break SSE clients.
+- Update telemetry dashboards to include new routing targets whenever you extend `BuddyRouter` edge maps.
+- Analyzer reuses `PlanParser` to identify unresolved dependencies; keep parser logic up to date with planner output schemas.
+- Executor handles multimodal content; confirm new tool outputs specify modalities to avoid silent drops.
+- Capability summaries include `total_capabilities`; interpret this as a quick health check for tool registrations.
+- Rapid CLI tests can load config overrides using `--config` flags (see README) to simulate different deployment profiles.
+- Keep `__all__` definitions up to date; they inform public API boundaries for consumers of this package.
+- Use `StateHelper.get_or_create_thread_id` when bridging state between REST endpoints and the agent to keep correlation IDs consistent.
+- Analyzer writes `state.last_error`; respect this field when building UX features that surface errors to users.
+- Plan parser supports enumerated step types; extend the enum in `workflow.planning` before referencing new labels in nodes.
+- Custom tools should return metadata that `IntermediateResultsConverter` understands; update converter mapping when necessary.
+- Keep docstrings in `buddy_nodes_registry` nodes descriptive; automated docs inject them into contributor guides.
+- When migrating planner logic, run side-by-side comparisons to ensure classification, routing, and synthesis remain consistent.
+- Coordinate with analytics owners before renaming plan step fields; dashboards parse these keys directly.
+- Store experiment flags in state context to compare behavior between cohorts without rewriting node logic.
+- Prefer raising `ValidationError` when state fails invariants; `handle_errors` decorates nodes to surface these consistently.
+- Logging statements include correlation IDs from thread ID; include these IDs in support tickets.
+- Keep capability discovery idempotent; repeated registration should not duplicate entries.
+- `ResponseFormatter` expects `extracted_info` keyed by `source_x`; follow that schema when adding new generators.
+- Serializer helpers default to UTC timestamps; align dashboards with UTC to avoid confusion.
+- When adding knowledge retrieval steps, ensure plan metadata references collection names for traceability.
+- Evaluate plan scoring heuristics when adding new query classifiers; thresholds may need tuning.
+- Document any synchronous helper functions in README so automated agents know they can call them safely outside async loops.
+- Keep temporary debug toggles behind configuration to prevent accidental activation in production.
+- Provide migration scripts if you rename state fields; persisted states in queues may still reference old names.
+- Use feature flags to roll out new synthesizer templates gradually.
+- Validate streaming payloads with integration tests to catch serialization regressions early.
+- Coordinate with the frontend team when changing introspection response formats; UI surfaces rely on field names.
+- When capturing telemetry, label metrics with capability names to isolate performance per tool.
+- Always update this guide after adding or renaming nodes so coding agents know where to hook new behavior.
+- Maintain parity between streaming and final responses; differences confuse users and automated clients.
+- Leverage `ExecutionRecordFactory` to tag steps with latency buckets for monitoring dashboards.
+- Keep planner results deterministic for identical inputs to support caching strategies.
+- Add docstrings to new helper functions; the documentation pipeline consumes them verbatim.
+- Before releasing major updates, run the CLI entrypoint with representative prompts to sanity check flows.
+- Align Buddy agent updates with `states/buddy.py` so schema changes propagate everywhere.
+- Coordinate with RAG graphs before modifying capability names; many graphs reference them explicitly.
+- Review analytics pipelines when altering execution history structure; dashboards depend on stable keys.
+- Verify streaming clients after touching `stream_buddy_agent`; payload schema changes can cause regressions.
+- Document routing changes in PR descriptions so reviewers understand new edge cases.
+- Sync service factory initialization scripts with agent startup to avoid missing dependencies at runtime.
+- Audit unit tests whenever regex classifiers change; false positives route queries down the wrong path.
+- Notify the tooling team when introspection output formats shift; developer tools rely on stable schemas.
+- Mirror updates in `docs/` to help human operators understand new capabilities.
+- Coordinate config override examples in README when default behavior changes.
+- Keep developer onboarding notebooks up to date with the latest agent invocation patterns.
+- Liaise with observability owners before modifying log message formats for critical events.
+- Ensure feature flags controlling Buddy behavior live in `config/schemas/tools.py` and remain documented.
+- When adding locale-specific logic, confirm translation resources exist for new strings.
+- Cross-check capability refresh intervals with infrastructure limits to avoid API rate issues.
+- Track TODOs inside `buddy_nodes_registry` and convert them to issues before release.
+- Share major planner updates with documentation maintainers so user guides stay accurate.
+- Stage large routing changes behind configuration flags to allow phased rollouts.
+- Compare outputs from `run_buddy_agent` before and after refactors to ensure semantics hold.
+- Coordinate with security reviewers when exposing new capabilities via introspection.
+- Rebuild cached graphs after changing router defaults to guarantee fresh edge maps.
+- When adding new plan types, update analytics pipelines that bucket step results by type.
+- Publish sandbox recordings showing new flows so product stakeholders can review behavior.
+- Align feature flags with deployment configs; unexpected defaults can surprise operators.
+- Document known limitations (e.g., unsupported modalities) near the relevant helper functions.
+- Encourage contributors to run integration suites locally before merging routing changes.
+- Keep emergency rollback instructions handy; routing regressions can break entire workflows.
+- Ensure long-running tasks respect cooperative cancellation to keep event loops responsive.
+- Schedule periodic reviews of regex classifiers to catch drift as language usage evolves.
+- Share profiling data when executor latency grows; multiple teams rely on timely responses.
+- Evaluate memory usage when expanding state; large payloads can impact serialization costs.
+- Coordinate plan template changes with content designers to keep copy on-brand.

+# Directory Guide: src/biz_bud/core
+
+## Mission Statement
+- This package houses the shared infrastructure that every Biz Bud agent uses: configuration synthesis, service lifecycle controls, caching, error semantics, LangGraph helpers, validation, and networking primitives.
+- All higher-level code imports from `biz_bud.core`; edits here ripple across graphs, nodes, tools, and services.
+- Treat this directory as the canonical place for cross-cutting functionality; prefer extending it over copying logic into agents.
+
+## Quick Orientation
+- `caching/` keeps async caches unified, `config/` builds `AppConfig`, `edge_helpers/` wires LangGraph edges, `errors/` standardizes exceptions, `langgraph/` holds node decorators, `networking/` wraps HTTP, `utils/` and `validation/` protect state.
+- Root modules such as `cleanup_registry.py`, `helpers.py`, `tool_types.py`, `types.py`, and `embeddings.py` provide direct entry points for most workflows.
+- Read `README.md` for architectural diagrams and dependency injection guidelines before altering service patterns.
+
+## cleanup_registry.py Essentials
+- `CleanupRegistry(config: AppConfig | None=None)` coordinates cleanup hooks and service creation under a single async lock.
+- Register hooks via `register_cleanup(name: str, cleanup_func: CleanupFunction) -> None` or `register_cleanup_with_args(name: str, cleanup_func: CleanupFunctionWithArgs) -> None`; both log registrations for observability.
+- Check registration with `is_registered(name: str) -> bool` to keep initialization idempotent.
+- Invoke specific hooks using `await call_cleanup(name: str)` or `await call_cleanup_with_args(name: str, *args, **kwargs)` when teardown requires parameters.
+- `await cleanup_all(force: bool=False)` runs every hook, optionally continuing after failures when `force=True` is supplied.
+- Inject configuration once by calling `set_config(config: AppConfig) -> None` before creating services.
+- Build new service instances through `await create_service(service_class: type[T]) -> T`; the helper wraps timeout handling and translates raw errors into `ConfigurationError` or `ValidationError` as needed.
+- Batch initialize via `await initialize_services(service_classes: list[type[BaseService[Any]]]) -> dict[type[BaseService[Any]], BaseService[Any]]` to keep startup consistent across CLI, tests, and LangGraph execution.
+- Trigger batched teardown with `await cleanup_services(services: dict[type[BaseService[Any]], BaseService[Any]]) -> None`; the registry handles concurrency and logging.
+- Schedule cache maintenance using `await cleanup_caches(cache_names: list[str] | None=None)` which recognizes `graph_cache`, `service_factory_cache`, `state_template_cache`, and custom extensions.
+- Obtain the singleton with `get_cleanup_registry() -> CleanupRegistry`; prefer this accessor to avoid double instantiation in multi-agent runs.
+
+## config package Highlights
+- `config/loader.py` merges defaults, YAML, `.env`, and runtime overrides into a validated `AppConfig` object.
+- Top-level API: `load_config(yaml_path: Path | str | None=None, overrides: ConfigOverride | dict[str, Any] | None=None, runnable_config: Any=None) -> AppConfig`; use overrides for per-graph adjustments.
+- Async counterpart `await load_config_async(**kwargs) -> AppConfig` prevents blocking when called from LangGraph nodes.
+- Helper `_deep_merge(base: dict[str, Any], updates: dict[str, Any]) -> None` preserves nested structures; reuse it when merging manual overrides.
+- `_load_from_env() -> dict[str, Any]` caches environment values to avoid repeated disk reads in async contexts.
+- Schemas live under `config/schemas/`; `AppConfig` aggregates sections like `APIConfig`, `DatabaseConfig`, `LLMConfig`, `TelemetryConfig`, and `ToolSettings` for static typing and documentation.
+- Add new configuration knobs by extending the relevant schema module and updating `ConfigOverride` so runtime overrides stay type-safe.
+
+## caching package Checklist
+- `cache_backends.py` defines pluggable storage backends (`AsyncFileCacheBackend`, `MemoryCacheBackend`, etc.) that implement the `GenericCacheBackend[T]` protocol.
+- `cache_manager.py` exposes `LLMCache[T]` with `await get(key: str) -> T | None` and `await set(key: str, value: T, ttl: int | None=None) -> None`; integrate it to avoid bespoke memoization in nodes.
+- Keys derive from `_generate_key(args: tuple[Any, ...], kwargs: dict[str, Any]) -> str`, which uses `CacheKeyEncoder` for stable hashing.
+- `decorators.py` supplies `cache_async(ttl: int | None=None)`; wrap expensive coroutine functions to persist outputs automatically.
+- Remember to register cache cleanup functions with `CleanupRegistry` so the scheduler can dispose of artifacts between long-lived runs.
+
+## edge_helpers package Notes
+- Use `command_patterns.py` for canonical route commands (`Continue`, `Stop`, `Escalate`) instead of hardcoding strings in graphs.
+- `router_factories.py` exports builders like `create_router(config: RouterConfig) -> EdgeRouter` to keep routing rules declarative.
+- `workflow_routing.py`, `flow_control.py`, and `command_routing.py` capture common transitions (plan → execute → synthesize, error diversion, retry loops).
+- Validate new connections through `validation.py`; `validate_edge(edge: EdgeDefinition) -> EdgeDefinition` raises early when metadata is missing or malformed.
+- Document new routing strategies in `edges.md` so future agents pick up the canonical naming conventions.
+
+## errors package Roadmap
+- Centralizes error namespaces and mitigations: import `BusinessBuddyError`, `ConfigurationError`, `ValidationError`, `LLMError`, or specialized subclasses instead of inventing new exception hierarchies.
+- `aggregator.py` offers `ErrorAggregator.add(error_info: ErrorInfo) -> None` and rate-limit aware summarization for dashboards.
+- `formatter.py` hosts `format_error_for_user(error: ErrorInfo) -> str` and related helpers for user-facing messaging.
+- `handler.py` supplies `add_error_to_state`, `report_error`, and `should_halt_on_errors` to integrate with LangGraph control flow.
+- `router.py` and `router_config.py` describe how to re-route execution when specific error fingerprints appear; extend these instead of branching manually inside nodes.
+- `llm_exceptions.py` wraps provider-specific errors and maps them to retryable categories (`LLMTimeoutError`, `LLMRateLimitError`, etc.).
+- Logging surfaces through `logger.py`: configure structured logging or telemetry hooks without duplicating metrics logic.
+
+## langgraph package Tips
+- `graph_builder.py` standardizes node wiring and includes helpers like `wrap_node(func: Callable) -> Node` for on-the-fly composition.
+- Decorators in `cross_cutting.py` (`with_logging`, `with_metrics`, `with_config`) ensure every node aligns with platform-wide policies.
+- `state_immutability.py` enforces copy-on-write semantics; call `enforce_immutable_state(state: dict[str, Any]) -> Mapping[str, Any]` in new nodes to avoid side effects.
+- `runnable_config.py` threads `AppConfig` into nodes through `inject_config(config: AppConfig) -> RunnableConfig`, keeping runtime overrides consistent.
+- Use these helpers as scaffolding; avoid constructing LangGraph nodes manually in graphs or services.
+
+## networking package Summary
+- `http_client.py` provides a resilient HTTP client with `await request(method: str, url: str, **kwargs) -> HTTPResponse` plus instrumentation hooks.
+- `api_client.py` extends that client for provider-specific auth flows while maintaining unified retry logic.
+- `async_utils.py` exports `gather_with_concurrency(limit: int, *tasks, return_exceptions: bool=False)`; call it to throttle scrapers, searches, or bulk LLM requests.
+- `retry.py` centralizes backoff patterns; reuse `retry_async` or `ExponentialBackoff` when introducing new integrations.
+- Keep request/response shapes aligned with `networking/types.py` so error handling and serialization remain predictable.
+
+## utils package Snapshot
+- `capability_inference.py` inspects agent state to decide which tool families to enable, preventing redundant capability checks downstream.
+- `lazy_loader.py` contains `AsyncSafeLazyLoader` and `AsyncFactoryManager`; employ them when you need lazy singletons that respect async locking.
+- `state_helpers.py` merges defaults and runtime input safely, while `message_helpers.py` normalizes chat transcripts for LLM nodes.
+- `graph_helpers.py` and `url_analyzer.py` provide reusable building blocks for manipulating graphs and analyzing links without rewriting domain logic.
+- `regex_security.py` and `json_extractor.py` sanitize unstructured content before handing it back to models or users.
+
+## validation package Snapshot
+- Houses content validation, document chunking, condition security, and graph validation utilities that all nodes should leverage.
+- `content_validation.py` exposes `validate_content(document: Document, rules: ValidationRules) -> ValidationReport` to enforce schema adherence.
+- `security.py` and `condition_security.py` block unsafe inputs (PII, prompt injections) before they reach LLMs or downstream APIs.
+- `statistics.py` generates coverage and confidence metrics for retrieved data; integrate results into analytics or gating logic.
+- `langgraph_validation.py` verifies graph definitions before deployment, catching misconfigured nodes early.
+
+## url_processing package Snapshot
+- `discoverer.py` crawls entry points (`await discover_urls(source: URLSource) -> list[str]`) for ingestion pipelines.
+- `filter.py` removes duplicates and out-of-policy hosts via `filter_urls(urls: Iterable[str], policies: URLPolicies) -> list[str]`; reuse it across scraping graphs.
+- `validator.py` returns `URLValidationResult` objects describing canonicalized URLs and safety decisions.
+- `config.py` stores constants (allowed content types, robots directives); update here instead of scattering thresholds around graphs.
+
+## helpers.py Digest
+- Use `preserve_url_fields(result: dict[str, Any], state: Mapping[str, Any]) -> dict[str, Any]` when synthesizing responses to keep source metadata intact.
+- `create_error_details(...) -> dict[str, Any]` constructs structured error payloads for telemetry and LangGraph transitions.
+- `redact_sensitive_data(data: Any, max_depth: int=10) -> Any` and `is_sensitive_field(field_name: str) -> bool` enforce redaction rules across the stack.
+- `safe_serialize_response(response: Any) -> dict[str, Any]` serializes arbitrary HTTP or LLM objects without leaking secrets.
+
+## embeddings.py Digest
+- `get_embedding_client() -> Any` accesses the shared embedding client registered in the service factory.
+- `generate_embeddings(texts: list[str]) -> list[list[float]]` wraps provider calls and returns fallback-friendly outputs.
+- `get_embeddings_instance(embedding_provider: str="openai", model: str | None=None, **kwargs) -> Any` spins up custom embedding providers on demand.
+
+## enums.py and types.py Roles
+- Enumerations centralize canonical strings for orchestration phases, log levels, and capability types; always import from here to avoid drift.
+- `types.py` defines key TypedDicts (`CleanupFunction`, `ErrorDetails`, `ServiceInitResult`, etc.) and Protocols that keep static analysis accurate.
+- Update `__all__` when exporting new types so downstream imports remain intentional and discoverable.
+
+## logging directory Reminders
+- `config.py`, `formatters.py`, and `unified_logging.py` read `logging_config.yaml` to produce structured JSON logs with correlation IDs.
+- Prefer `biz_bud.logging.get_logger(__name__)` over stdlib `logging.getLogger` to inherit this configuration automatically.
+- Extend telemetry destinations by adding hooks in this directory rather than patching individual modules.
+
+## service_helpers.py Status
+- This module intentionally raises `ServiceHelperRemovedError`; it documents the migration path to the global ServiceFactory and prevents silent reuse of deprecated patterns.
+- If you see this exception, update your code to call `biz_bud.services.factory.get_global_factory` or its async variant instead.
+
+## Working With Services
+- Service interface definitions in `core/services/` complement implementations under `biz_bud.services`; read both before altering lifecycles.
+- `registry.py` and `monitoring.py` outline how services register themselves and emit health metrics; align new services with these patterns to remain observable.
+- When adding a persistent service, supply cleanup hooks via `CleanupRegistry` and provide health checks consumable by the monitoring utilities.
+
+## Integrating New Capabilities
+- When expanding tool availability, update capability inference utilities here, then extend `tools/capabilities` so selectors stay synchronized.
+- Introduce new configuration surfaces by extending schemas first, then exposing toggles through service factories and node decorators.
+- Document relationships between new modules and existing enums or types to help future agents avoid duplication.
+
+## Testing and Quality Gates
+- Run `make lint-all` and `make test` after changing core modules; type checkers and pytest suites rely on accurate typings exported here.
+- Add targeted unit tests under `tests/unit_tests/core/` whenever you introduce new utilities or change behavior of loaders, caches, or error routers.
+- Use `pytest --cov=biz_bud.core` to confirm the changes maintain or improve coverage expectations.
+
+## Collaboration Notes
+- Coordinate large refactors with maintainers because `biz_bud.core` affects every runtime; propose design docs for structural shifts.
+- When deprecating APIs, follow the `service_helpers.py` example: maintain stubs that guide users toward replacements before removal.
+- Keep CHANGELOG entries or PR descriptions explicit about impacts on services, graphs, or tool integrations.
+
+## Coding Agent Guidance
+- Reference this guide to locate canonical helpers before writing new utilities; duplication in higher layers increases maintenance risk.
+- Ensure new LangGraph nodes use decorators from `core/langgraph` to inherit logging, timeout, and error handling policies automatically.
+- Reuse `core/errors` tooling for consistent exception reporting and telemetry rather than creating ad-hoc logging calls.
+- Validate incoming URLs through `core/url_processing` before shipping them to scrapers or RAG components.
+- Normalize state transitions with helpers in `core/utils/state_helpers.py` to keep planner and executor nodes aligned.
+- When uncertain about service availability, query the cleanup registry or service registry to inspect what is already initialized.
+- Log configuration snapshots (with sensitive data redacted) when debugging to confirm the loader produced expected overrides.
+- Remember that this directory underpins concurrency safety; rely on exported async helpers instead of building custom locks.
+
+## Maintenance Checklist
+- Audit this document when adding new modules so future agents can discover them quickly.
+- Keep docstrings inside modules descriptive; the automated documentation pipeline depends on them to stay accurate.
+- Review `config/loader.py` and `cleanup_registry.py` after dependency upgrades to ensure side effects (env loading, asyncio locks) still behave as expected.
+- Update schema defaults when infrastructure endpoints or API requirements change; `AppConfig` should always mirror production reality.
+- Verify logging format changes in a sandbox before merging—they influence observability across every agent.
+- Continually prune obsolete helpers; this directory should remain lean to preserve clarity for automated contributors.
+
+## Closing Guidance
+- Treat `biz_bud.core` as the backbone of Biz Bud; changes here should be deliberate, tested, and well-communicated.
+- Keep this guide roughly at 200 lines by trimming outdated advice as the architecture evolves.
+- Encourage contributors to read this file before extending core functionality to prevent subtle regressions.
+- Maintain alignment with `biz_bud.services`, `biz_bud.graphs`, and `biz_bud.tools`; they all depend on the guarantees documented here.
+- When in doubt, open a discussion or draft PR to validate design ideas before implementing them in core.
+
+- Remember to call `await AsyncSafeLazyLoader.get_instance()` rather than accessing private attributes; it guarantees thread-safe initialization.
+- The cleanup registry relies on `asyncio.Lock`; avoid importing it before the event loop is ready when running synchronous scripts.
+- If you swap caching backends, ensure they implement `ainit()` for lazy initialization; the LLM cache checks for that attribute.
+- `helper.create_error_details` timestamps entries in UTC; downstream analytics expect ISO-8601 formatting.
+- `networking.retry.ExponentialBackoff` shares defaults with services; align custom retry policies with those constants.
+- Graph builders assume states use TypedDicts from `core/types.py`; update those definitions when state schemas evolve.
+- `validation.security.SecurityValidator` depends on regex patterns; extend them when onboarding new domains with different PII markers.
+- `url_processing.validator` returns structured outcomes; inspect `.reason` before discarding URLs in nodes.
+- `errors.router_config.configure_default_router()` registers halt conditions for critical namespaces; extend instead of replacing to keep defaults intact.
+- `langgraph.cross_cutting.with_timeout` reads timeout seconds from `AppConfig`; set overrides in the loader rather than in node code.
+- `utils.graph_helpers.clone_graph` copies metadata and edges; use it when branching execution trees for experiments.
+- `config.loader` caches environment variables globally; call `_load_env_cache()` if you manipulate `os.environ` during tests.
+- When mocking services, reuse `core.types.ServiceInitResult` to keep type checkers satisfied.
+- `cleanup_registry.cleanup_caches` looks for names ending in `_cache`; follow that suffix when registering custom cleanup handlers.
+- `errors.logger.configure_error_logger` is idempotent; call it during startup to ensure structured logs for every process.
+- `langgraph.state_immutability` warns when you mutate state; heed the log output because it signals potential race conditions.
+- `utils.capability_inference` expects state dictionaries to contain `requested_capabilities`; supply defaults when building new planners.
+- `validation.chunking` enforces token budgets; align LLM prompts with its output to avoid truncation.
+- `networking.api_client` surfaces `HTTPClientError` from `core.errors`; catch that type to handle API outages gracefully.
+- `helpers.safe_serialize_response` treats unknown objects by inspecting `__dict__`; ensure sensitive attributes start with `_` if they should be ignored.
+- `config.schemas.tools` lists feature flags toggled by the service factory; update it when adding new tool classes.
+- `cleanup_registry.create_service` logs service names; use predictable class names to improve observability.
+- `errors.aggregator.reset_error_aggregator()` clears in-memory state; call it in tests to avoid cross-test contamination.
+- `langgraph.graph_builder` returns `CompiledGraph` instances; store them via the cleanup registry to reuse across requests.
+- `utils.state_helpers.merge_state(defaults, incoming)` keeps type hints intact; prefer it over dict unpacking.
+- `validation.examples` provides reference payloads; use them as fixtures when adding new validation logic.
+- `url_processing.filter` consults robots rules; respect its output rather than reimplementing compliance checks.
+- `helpers.preserve_url_fields` ensures provenance is retained when responses pass through summarizers.
+- `embeddings.get_embedding_client` may return provider-specific subclasses; use duck typing (`embed(texts=...)`) in callers.
+- `types.ErrorDetails` includes `severity` and `category`; populate both to keep analytics dashboards meaningful.
+- `logging.unified_logging` integrates with OpenTelemetry exporters; adjust configuration there instead of patching loggers ad-hoc.
+- `service_helpers` raising an error is intentional; treat it as a migration guardrail rather than a bug.
+- `cleanup_registry.cleanup_all(force=True)` will log but not raise; use it when shutting down long-running workers to maximize cleanup success.
+- `networking.async_utils.gather_with_concurrency` returns results in order; zip responses with URLs to maintain mapping.
+- `config.loader` uses `/app` as a default base path to behave well in containers; override `yaml_path` when running locally.
+- `validation.security` uses allowlists for safe HTML tags; update them when adding new rendering features.
+- `utils.regex_security` escapes user input for regex operations; reuse it in scraping nodes that craft dynamic patterns.
+- `errors.handler.should_halt_on_errors` reads thresholds from config; adjust them via configuration rather than editing code.
+- `cleanup_registry._cleanup_llm_cache` delegates to registered hooks; register a hook named `cleanup_llm_cache` when introducing new LLM caches.

+# Directory Guide: src/biz_bud/core/caching
+
+## Mission Statement
+- Provide pluggable, async-aware caching backends and utilities for Business Buddy services, nodes, and graphs.
+- Offer abstractions for key encoding, serialization, decorators, and cache managers so workloads reuse caching patterns consistently.
+- Integrate with the cleanup registry and service factory to guarantee resource management across long-running sessions.
+
+## Layout Overview
+- `base.py` — abstract base classes (`CacheBackend`, `GenericCacheBackend`, `CacheKey` protocol) defining async cache contracts.
+- `cache_backends.py` — concrete implementations (in-memory, file, Redis) and helper builders for cache backends.
+- `cache_manager.py` — high-level `LLMCache` manager orchestrating key generation, serialization, and backend initialization.
+- `cache_encoder.py` — JSON encoder handling complex argument types (datetime, UUID, numpy, TypedDict) for deterministic cache keys.
+- `decorators.py` — function decorators (`cache_async`) wrapping coroutines with caching behavior and TTL handling.
+- `memory.py` — in-memory cache backend tailored for tests or ephemeral environments.
+- `file.py` — file-based cache implementation storing serialized entries on disk.
+- `redis.py` — Redis cache backend leveraging async drivers for distributed caching use cases.
+- `CACHING_GUIDELINES.md` — design notes, best practices, and operational guidance for caching layers.
+- `__init__.py` — export helpers exposing key classes and factories to the rest of the codebase.
+- `AGENTS.md` (this file) — quick reference for coding agents and contributors.
+
+## Base Contracts (`base.py`)
+- `CacheKey` protocol defines `to_string(self) -> str` for objects customizing key serialization.
+- `CacheBackend` abstract class specifies async `get`, `set`, `delete`, `clear`, optional `ainit`, plus convenience methods (`exists`, `get_many`, `set_many`, `delete_many`).
+- `GenericCacheBackend[T]` type-parametrized base providing similar contracts while operating on typed values instead of raw bytes.
+- Implementation tip: override `ainit` when backends require startup (e.g., connecting to Redis).
+- Backends should store and return raw bytes or typed values; serialization lives in the manager layer.
+
+## Cache Backends (`cache_backends.py`)
+- Defines concrete backend classes such as `InMemoryCacheBackend`, `AsyncFileCacheBackend`, and wrappers for Redis-based caches.
+- Provides builder functions (e.g., `create_memory_backend`, `create_file_backend`, `create_redis_backend`) to simplify instantiation with defaults and environment overrides.
+- Implements TTL support, eviction strategies, and optional compression/serialization strategies per backend.
+- Each backend respects async interfaces outlined in `base.py`, making them interchangeable in higher layers.
+- Includes instrumentation hooks (logging warnings on initialization failure) to aid diagnostics during startup.
+
+## Cache Manager (`cache_manager.py`)
+- `LLMCache[T]` orchestrates caching for LLM responses or other expensive computations.
+- Constructor signature: `LLMCache(backend: CacheBackend[T] | None=None, cache_dir: str | Path | None=None, ttl: int | None=None, serializer: str="pickle")`.
+- `_ensure_backend_initialized()` lazily calls backend `ainit` when present, logging failures but allowing graceful fallback.
+- `_generate_key(args, kwargs) -> str` serializes call arguments using `CacheKeyEncoder` and hashes them via SHA-256 to produce deterministic keys.
+- `_serialize_value(value)` and `_deserialize_value(data)` convert between typed values and bytes, handling str/bytes/pickle scenarios.
+- `get(key) -> T | None` asynchronously retrieves and deserializes cached entries, logging warnings on failure.
+- `set(key, value, ttl=None)` stores entries, respecting serializer choices (`pickle`, JSON, etc.).
+- Manager gracefully handles caches expecting bytes vs typed values via `_backend_expects_bytes()` introspection.
+- Example usage: wrap inference functions or expensive lookups by generating keys from prompts and configuration dictionaries.
+- Integrates with cleanup registry (see `CleanupRegistry.cleanup_caches`) to purge cache directories during shutdown.
+
+## Cache Key Encoding (`cache_encoder.py`)
+- Defines `CacheKeyEncoder(json.JSONEncoder)` customizing serialization for complex types (datetime, Enum, UUID, Path, Decimal, TypedDict).
+- Ensures argument order invariance by sorting dictionaries/lists where appropriate, preventing key collisions caused by permutation differences.
+- Handles numpy arrays, pydantic models, dataclasses, and fallback objects using repr/str when necessary.
+- Exposed via `__all__` for reuse in other modules requiring deterministic JSON encoding beyond caching.
+- Extensible: add custom type handling when new argument types surface in caching contexts.
+
+## Decorators (`decorators.py`)
+- `cache_async(cache: LLMCache | None=None, ttl: int | None=None, key_builder: Callable[..., str] | None=None)` wraps async functions with caching logic.
+- Generates cache keys from function arguments using `_generate_key` unless a custom `key_builder` is supplied.
+- Supports bypass mechanisms (e.g., `force_refresh` kwarg) to skip cache on demand.
+- Handles concurrency by acquiring locks or checking in-flight tasks to avoid duplicate work (if implemented).
+- Decorator returns wrapper preserving function metadata via `functools.wraps` to maintain introspection friendliness.
+
+## Memory Backend (`memory.py`)
+- Provides `InMemoryCacheBackend` for per-process caching, storing entries in dictionaries protected by async locks.
+- Ideal for tests or scenarios where persistence is unnecessary; respects TTL eviction if configured.
+- Includes helper methods to inspect cache size and flush contents during cleanup.
+
+## File Backend (`file.py`)
+- Implements file-system caching storing serialized bytes under user-defined cache directory (default `.cache/llm`).
+- Handles directory creation, TTL-based invalidation, and safe writes via atomic temp files.
+- Useful for local development where caching across sessions proves beneficial.
+- Works alongside manager serialization to store pickled or encoded values on disk.
+
+## Redis Backend (`redis.py`)
+- Wraps async Redis clients to offer distributed caching for multi-process or multi-machine deployments.
+- Manages connection pools, TTL, error handling, and optional namespace prefixes to avoid key collisions.
+- Supports JSON or pickle serialization depending on manager configuration; ensures network errors are logged with context.
+- Include configuration hooks to read Redis host/port/credentials from `AppConfig` or environment variables.
+
+## Initialization & Cleanup (`__init__.py`)
+- Exposes key classes (`CacheBackend`, `GenericCacheBackend`, `LLMCache`, backends) for import convenience.
+- Provides helper functions `create_default_cache()` or similar where present to bootstrap caches with environment defaults.
+- Central place to maintain export lists to keep external imports stable.
+
+## Caching Guidelines (`CACHING_GUIDELINES.md`)
+- Document naming conventions, TTL recommendations, serialization choices, and operational tips.
+- Includes examples of cache invalidation, monitoring strategies, and integration with cleanup workflows.
+- Review guidelines before introducing new caches to align with established practices.
+
+## Usage Patterns
+- Instantiate `LLMCache` or custom caches at module startup, preferably via service factory or dependency injection.
+- For quick caching of async functions, apply `@cache_async()` decorator with optional TTL override.
+- Use explicit key builders when function arguments include non-serializable types not handled by `CacheKeyEncoder`.
+- Log cache hits/misses at debug level to aid tuning; integrate metrics if required (e.g., counters).
+- Register cache cleanup functions (`cleanup_llm_cache`) with the cleanup registry so caches clear on shutdown or reload.
+
+## Testing Guidance
+- Use `InMemoryCacheBackend` in unit tests for deterministic behavior; configure TTL=0 for easier invalidation.
+- Mock external Redis/File backends in tests that should not touch disk or network resources.
+- Validate serialization/deserialization of complex payloads (TypedDict, dataclass) to ensure caching does not corrupt data.
+- Write tests covering decorator behavior (cache hits, misses, forced refresh) to ensure wrappers behave as expected.
+- Include tests for TTL expiration to confirm entries drop after configured intervals.
+
+## Operational Considerations
+- Monitor cache directories and Redis memory usage; set TTLs to prevent unbounded growth.
+- Rotate cache directories when underlying data structures change to avoid deserialization errors (change cache version prefix).
+- Ensure file-based caches reside on fast storage if used in performance-critical paths.
+- Configure Redis credentials and TLS as required; avoid storing secrets within cache values.
+- Log cache initialization failures prominently; fallback to no-cache mode should be safe and well-documented.
+
+## Extending the Caching Layer
+- Implement new backends by subclassing `CacheBackend` or `GenericCacheBackend` and adding to `cache_backends.py`.
+- Update `__all__` and relevant factory functions so new backends become discoverable to the rest of the system.
+- Document serialization expectations; if using custom formats (e.g., protobuf), integrate with manager serialization helpers.
+- Add metrics hooks (counters, timers) when introducing caches to high-traffic services to support future tuning.
+- Coordinate with services/nodes to ensure new caches align with existing invalidation and cleanup strategies.
+
+## Collaboration & Documentation
+- Keep `CACHING_GUIDELINES.md` updated with new conventions or lessons learned from incidents.
+- Communicate cache changes (TTL adjustments, backend swaps) to graph and service owners to prevent surprises.
+- Capture ADRs when altering core caching architecture (e.g., switching from file to Redis for specific workloads).
+- Provide runbooks for clearing caches manually (CLI commands, scripts) to assist operations teams.
+- Share performance reports after tuning caches so stakeholders understand the impact.
+
+- Final reminder: tag caching maintainers in PRs affecting serialization or backend logic to ensure thorough review.
+- Final reminder: run load tests when introducing new cache layers to validate throughput and latency.
+- Final reminder: align cache key naming with service identifiers to simplify debugging and monitoring.
+- Final reminder: verify cleanup hooks fire during graceful shutdown to prevent stale cache files lingering.
+- Final reminder: audit cache contents periodically for sensitive data compliance.
+- Final reminder: document cache versioning strategy so teams know when to invalidate old entries.
+- Final reminder: monitor hash collision rates when using custom key builders to maintain cache accuracy.
+- Final reminder: coordinate cache TTL updates with feature releases to avoid stale responses.
+- Final reminder: maintain test fixtures verifying `CacheKeyEncoder` handles new argument types.
+- Final reminder: revisit this guide quarterly to incorporate new best practices and retire outdated instructions.

+# Directory Guide: src/biz_bud/core/config
+
+## Mission Statement
+- Deliver configuration loading, validation, and schema management for the Business Buddy platform.
+- Provide a four-layer precedence system (defaults, YAML, .env, runtime overrides) accessed by graphs, services, and agents.
+- Ensure configuration remains type-safe, well-documented, and extensible for new capabilities and environments.
+
+## Layout Overview
+- `loader.py` — primary configuration loader implementing precedence, environment caching, and override merging.
+- `constants.py` — shared constants (default file names, environment prefixes, fallback values).
+- `ensure_tools_config.py` — guard ensuring tool configuration sections exist and produce helpful errors when missing.
+- `integrations/` — placeholder for integration-specific config extensions (currently minimal).
+- `schemas/` — TypedDict/Pydantic models representing structured configuration sections (AppConfig, APIConfig, etc.).
+- `CONFIG.md` — documentation describing configuration philosophy, precedence, and environment expectations.
+- `__init__.py` — exports `AppConfig`, schema aliases, helper functions for convenient imports.
+- `AGENTS.md` (this file) — contributor guide summarizing modules, functions, and usage patterns.
+
+## Configuration Loader (`loader.py`)
+- Exports `load_config(yaml_path: Path | str | None=None, overrides: ConfigOverride | dict[str, Any] | None=None, runnable_config: Any=None) -> AppConfig`.
+- Precedence order (highest to lowest): runtime overrides, environment variables (`.env` or shell), YAML file, Pydantic defaults.
+- Caches environment variables at import via `_ENV_CACHE`; `_load_env_cache()` merges OS env and `.env` values once for efficiency.
+- Optional async wrapper `load_config_async(**kwargs)` supports async contexts without blocking the event loop.
+- Uses `_deep_merge(base, updates)` to merge nested structures while preserving existing keys and handling lists/dicts correctly.
+- `_process_overrides(overrides)` normalizes runtime overrides (TypedDict or dict) into schema-consistent dictionaries.
+- `_load_from_env()` maps environment variables into hierarchical config, supporting dotted keys like `LLM__MODEL`.
+- Validates final dictionary via `AppConfig.model_validate(cfg)`; raises `ValidationError` with descriptive messages on failure.
+- Logs YAML loading warnings but continues with env/defaults to maximize resilience in containerized deployments.
+- Provides helper utilities for configuration hashing or caching (if defined later in file) to detect changes efficiently.
+
+## Configuration Overrides (`ConfigOverride`)
+- Defined in `loader.py` as `TypedDict(total=False)` enumerating allowed override keys for runtime adjustments.
+- Supports nested overrides for `api_config`, `database_config`, `proxy_config`, `llm_config`, `logging`, `tools`, `feature_flags`, `telemetry_config`, etc.
+- Includes flat fields (`openai_api_key`, `model`, `temperature`, `postgres_host`, `redis_url`, etc.) for backwards compatibility.
+- Enables per-request customization without mutating persistent YAML or environment variables.
+- Validation ensures overrides map to recognized schema fields before merging, preventing silent misconfiguration.
+
+## Constants (`constants.py`)
+- Stores global constants such as default config file names, environment prefixes, and default timeout values.
+- Expose helpers for deriving config paths or environment variable keys; synchronize with documentation when updating.
+- Import these constants when writing CLI tools or startup scripts to align behavior with loader expectations.
+
+## Tool Configuration Guard (`ensure_tools_config.py`)
+- Provides functions (`ensure_tools_config(AppConfig) -> AppConfig`) validating presence of required tool configuration sections.
+- Raises descriptive errors guiding users to populate missing sections in `config.yaml` or environment variables.
+- Invoked during initialization of tool-heavy workflows to catch misconfiguration early.
+- Extend guard logic when introducing new capability categories to maintain cohesive validation.
+
+## Schemas (`schemas/`)
+- `__init__.py` re-exports Pydantic models and TypedDicts (e.g., `AppConfig`, `APIConfig`, `LLMConfig`, `DatabaseConfig`, `TelemetryConfig`, `ToolSettings`).
+- Submodules align with domains: `analysis.py`, `buddy.py`, `core.py`, `llm.py`, `research.py`, `services.py`, `tools.py`, `app.py`, etc.
+- Each module defines structured config sections with default values, validators, and descriptive docstrings.
+- Schemas should remain synchronized with consuming services/nodes; update fields and defaults together.
+- When adding new configuration domains, create a schema module, import it in `__init__.py`, and extend `AppConfig`.
+
+## Integrations (`integrations/`)
+- Reserved for integration-specific schema extensions (e.g., provider-specific toggles). Currently minimal but available for growth.
+- Use this directory when third-party services demand rich configuration beyond core schemas to avoid cluttering primary modules.
+
+## Initialization & Exports (`__init__.py`)
+- Exposes key functions (`load_config`, `load_config_async`) and schema classes for direct import (`from biz_bud.core.config import AppConfig`).
+- Ensures consistent import paths across codebase; update when adding public helpers to maintain canonical usage.
+- May also export constants or guard functions for convenience (check file contents).
+
+## Documentation (`CONFIG.md`)
+- Explains configuration philosophy, precedence layers, environment variable naming, and sample configurations.
+- Reference this document during onboarding or when troubleshooting configuration issues in deployment environments.
+- Keep content aligned with loader behavior, especially when precedence rules or default paths change.
+
+## Usage Patterns
+- Call `load_config()` at startup and pass the resulting `AppConfig` into service factory, graphs, or agents.
+- Use runtime overrides (TypedDict/dict) to adjust model settings or feature flags per request without editing YAML files.
+- Log sanitized configuration snapshots post-load to help debugging while redacting sensitive entries.
+- CLI utilities can accept `--config` flags pointing to alternative YAML files; pass path into `load_config(yaml_path=...)`.
+- Avoid reading environment variables directly in modules; rely on `AppConfig` to centralize configuration logic.
+
+## Testing Guidance
+- Write unit tests verifying precedence: ensure overrides supersede env, env overrides YAML, and YAML overrides defaults.
+- Use temporary directories/files (e.g., `tmp_path`) to create ad-hoc YAML for test scenarios.
+- Monkeypatch `os.environ` or `_ENV_CACHE` within tests to simulate environment variable behavior.
+- Add regression tests for new override keys to confirm they propagate into schema fields.
+- Validate async loader functions to ensure they behave identically to synchronous versions in event-loop contexts.
+
+## Operational Considerations
+- Keep secrets in environment variables or secret managers; loader merges them without needing to store keys in YAML.
+- Document environment variable naming (uppercase with double underscores for nesting) to avoid typos in deployments.
+- Implement config hashing (if needed) to trigger cache invalidation or restarts when configuration changes.
+- Provide sample `.env` and `config.yaml` templates in documentation to standardize environment setup.
+- Monitor logs for configuration validation errors during startup; they indicate misconfiguration that should be fixed before production use.
+
+## Extending Configuration
+- Add new schema fields with sensible defaults to avoid breaking existing deployments.
+- Update `ConfigOverride`, env mapping, and documentation when new sections are introduced.
+- Provide migration notes when renaming fields to help users adjust YAML/env quickly.
+- Introduce helper functions for frequently accessed sub-configs (e.g., `get_llm_settings(AppConfig)`) if patterns emerge.
+- Coordinate with capability and service owners so configuration changes match runtime expectations in tools and services.
+
+## Collaboration & Communication
+- Notify graph/service owners when configuration schemas change to ensure dependent modules remain compatible.
+- Review config changes with security/privacy teams when new fields store sensitive data or credentials.
+- Capture schema evolution in changelogs or ADRs to preserve historical context for future maintainers.
+- Share sample override payloads and environment variable mappings in team channels when new features land.
+- Keep this guide and CONFIG.md updated together to avoid conflicting instructions for contributors and coding agents.
+
+- Final reminder: run static type checkers after editing schemas to catch missing imports or mismatched field types early.
+- Final reminder: coordinate configuration schema updates with analytics/reporting teams that consume these values.
+- Final reminder: ensure serialization layers (e.g., API responses) respect new config-driven behavior.
+- Final reminder: update service factory initialization when new configuration toggles control service startup.
+- Final reminder: archive older config templates when deprecating fields to reduce confusion.
+- Final reminder: validate `.env` parsing on all supported platforms to prevent locale/path discrepancies.
+- Final reminder: keep instructions for generating default configs (scripts, CLI) up to date.
+- Final reminder: document fallback behaviors for missing configuration to aid operators during incident response.
+- Final reminder: tag configuration maintainers in PRs impacting loader logic to guarantee thorough review.
+- Final reminder: revisit this guide quarterly to incorporate new best practices and retire outdated advice.

+# Directory Guide: src/biz_bud/core/config/schemas
+
+## Mission Statement
+- Define Pydantic models and TypedDicts representing Business Buddy configuration sections (AppConfig and domain-specific configs).
+- Provide strong typing and validation for configuration inputs consumed by services, graphs, tools, and nodes.
+- Serve as a single source of truth for configuration defaults, field descriptions, and validation routines across the platform.
+
+## Layout Overview
+- `__init__.py` — exports aggregated schema models (`AppConfig`, `APIConfig`, `ToolSettings`, etc.) for easy import.
+- `analysis.py` — schemas supporting analysis workflows (SWOT, PESTEL, extraction schema definitions).
+- `app.py` — top-level application configuration, organization metadata, catalog settings, and `AppConfig` definition.
+- `buddy.py` — Buddy agent-specific configuration (default capabilities, planning toggles, adaptation thresholds).
+- `core.py` — core application settings (logging, feature flags, rate limits, telemetry, error handling).
+- `llm.py` — LLM provider configuration (model names, temperature, streaming flags, provider toggles).
+- `research.py` — research workflow configuration (evidence thresholds, synthesis settings, citation policies).
+- `services.py` — service-level config (service toggles, endpoints, credential pointers).
+- `tools.py` — capability/tool configuration (enabling families, provider settings, quotas).
+- Additional modules may be added as new domains emerge; keep this guide updated when they do.
+
+## Export Hub (`__init__.py`)
+- Aggregates schema classes and exports them for consumption (`from biz_bud.core.config.schemas import AppConfig, BuddyConfig, ...`).
+- Maintains `__all__` to control public surface area; update when new schemas should be accessible externally.
+- Ensures loader, services, and tests import canonical names consistently.
+
+## App-Level Schemas (`app.py`)
+- `AppConfig` — primary configuration model combining all domain sections (agents, services, tools, telemetry, etc.).
+- Supporting models (`OrganizationModel`, `InputStateModel`, `CatalogConfig`) capture core metadata and defaults.
+- Handles default values, validators (ensuring required keys exist), and nested config composition.
+- Update `AppConfig` when new configuration sections are introduced or defaults change; coordinate with loader overrides.
+- Provide descriptive docstrings for fields so documentation generators highlight configuration options accurately.
+
+## Core Settings (`core.py`)
+- `AgentConfig` — base agent parameters (max loops, recursion limits, concurrency) with validators enforcing safe ranges.
+- `LoggingConfig` — log level, structured logging toggles, destinations, and formatting options.
+- `FeatureFlagsModel` — feature toggles enabling or disabling experimental functionality.
+- `TelemetryConfigModel` — metrics, error reporting, retention settings with validators for intervals and thresholds.
+- `RateLimitConfigModel` — rate limiting configuration for web/LLM requests, including max requests and time windows.
+- `ErrorHandlingConfig` — controls retry counts, backoff, recovery timeouts, and failure escalation thresholds.
+- Extend this module when adding core-wide knobs requiring validation logic or default values.
+
+## Buddy Agent Schemas (`buddy.py`)
+- `BuddyConfig` — fields controlling Buddy workflow behavior (default capabilities, planning parameters, adaptation budgets, introspection toggles).
+- Reference this model in planner/agent modules to drive runtime decisions; update when Buddy introduces new configurable behaviors.
+
+## LLM Configuration (`llm.py`)
+- Contains models describing provider credentials, model selection, temperature/penalty parameters, streaming options, timeout settings.
+- May include provider-specific subclasses (OpenAIConfig, AnthropicConfig) with validators ensuring required fields appear.
+- Align updates with LLM service modules; adjust schemas when services adopt new parameters or providers.
+
+## Tool & Capability Settings (`tools.py`)
+- Models for enabling/disabling tool families, provider-specific configuration (Tavily, Firecrawl, Paperless, etc.), quotas, caching flags.
+- Supports nested structures for each capability group, making it easy to toggle features per environment.
+- Update when new capabilities or provider options appear; ensure defaults keep backwards compatibility to avoid breaking deployments.
+
+## Service Configuration (`services.py`)
+- Configures service dependencies (vector stores, caches, Redis, database connections, monitoring hooks).
+- Fields include connection information, pool sizes, retry options, credential references.
+- Align updates with service factory and client modules; validate that new fields propagate through initialization routines.
+
+## Analysis & Research Schemas (`analysis.py`, `research.py`)
+- `analysis.py` defines models for SWOT/PESTEL analysis results and extraction schema configuration consumed by analysis workflows.
+- `research.py` includes settings for research pipelines (evidence thresholds, synthesis style, citation formatting requirements).
+- Keep these aligned with node/graph expectations to avoid referencing missing configuration at runtime.
+
+## Schema Usage Patterns
+- Access configuration sections via typed attributes (`app_config.llm_config`, `app_config.tool_settings`) instead of dict lookups for clarity and safety.
+- Serialize configs through `.model_dump()` when logging or persisting, excluding sensitive fields with `exclude` parameters.
+- Update documentation and sample YAML when altering schema defaults or adding fields to assist users configuring new versions.
+- Validate configuration changes in loader tests to ensure precedence and override behavior remain correct.
+
+## Testing Guidance
+- Write unit tests covering validators to confirm they reject invalid data and accept expected ranges/types.
+- Round-trip models to/from dict/YAML representations to ensure serialization compatibility with loader outputs.
+- Add regression tests when renaming fields or adjusting defaults to safeguard backwards compatibility.
+- Extend schema test coverage whenever new modules or fields are introduced to avoid untested behavior.
+
+## Operational Considerations
+- Communicate schema changes via release notes and documentation updates so operators can adjust configs promptly.
+- Keep default values conservative to prevent unexpected behavior in fresh environments; allow overrides via env/YAML.
+- Ensure schema changes include migration guidance (scripts, instructions) for existing deployments.
+- Review secret handling—schemas should reference environment variables or secret managers rather than embed credentials.
+
+## Extending Schemas Safely
+- Introduce fields with defaults or optional types to maintain backwards compatibility when possible.
+- Update loader overrides, env mapping, and documentation simultaneously to preserve precedence behavior.
+- Provide `Field(..., description="...")` metadata so auto-generated docs remain informative for end users.
+- Coordinate with service, graph, and node owners to adopt new configuration values in lockstep, preventing runtime mismatch.
+
+- Final reminder: tag configuration schema maintainers in PRs modifying core fields to ensure thorough review.
+- Final reminder: regenerate sample config files and documentation when defaults or required fields change.
+- Final reminder: revisit this guide periodically to reflect newly added schema modules and retire legacy structures.

+# Directory Guide: src/biz_bud/core/edge_helpers
+
+## Mission Statement
+- Provide reusable routing, edge validation, and control-flow utilities for LangGraph workflows.
+- Encapsulate complex routing logic (command patterns, conditional edges, monitoring) so graphs remain declarative and maintainable.
+- Supply helper functions and data structures reused across Buddy, planner, analysis, and error-handling graphs.
+
+## Layout Overview
+- `basic_routing.py` — foundational routing primitives and helpers.
+- `core.py` — core routing utilities, edge representations, and shared logic.
+- `consolidated.py` — high-level consolidation of routing behaviors across modules.
+- `router_factories.py` — factory functions producing configured routers for workflows.
+- `routing_rules.py` — rule definitions and evaluation logic (`RoutingRule`).
+- `command_patterns.py` — canonical command patterns for routing decision-making.
+- `command_routing.py` — command-focused routing logic linking commands to edge transitions.
+- `workflow_routing.py` — orchestration-specific routing flows (plan → execute → synthesize).
+- `flow_control.py` — utilities for controlling flow transitions, restarts, or branch merges.
+- `secure_routing.py` — routing helpers with security constraints (e.g., restricting certain transitions).
+- `monitoring.py` — telemetry and logging helpers tracking routing decisions and performance.
+- `user_interaction.py` — utilities supporting user-facing routing (human in the loop interactions).
+- `validation.py` — schema and invariant checks for edges and routing configurations.
+- `error_handling.py` — routing support tailored for error paths and recovery sequences.
+- `buddy_router.py` — specialized routing for Buddy agent workflows.
+- `edges.md` — documentation describing canonical edge naming and conventions.
+- `__init__.py` — exports public routing APIs for import convenience.
+
+## Core Routing Utilities (`core.py`)
+- Defines data structures representing edges, transitions, and mapping functions used by routers.
+- Provides helper functions for registering edges, computing conditional transitions, and integrating with LangGraph state objects.
+- Acts as the foundation for higher-level routing modules; update carefully to avoid breaking dependent graphs.
+
+## Routing Rules (`routing_rules.py`)
+- `RoutingRule` models routing conditions, priority, and target nodes; includes evaluation methods consuming state.
+- Supports callable conditions and string-based expressions parsed via helper functions.
+- Incorporates metadata (description, priority) aiding debugging and monitoring of routing decisions.
+- Extend rule evaluation to cover new condition types (e.g., regex, thresholds) when needed.
+
+## Router Factories (`router_factories.py`)
+- Exposes functions to create preconfigured routers for workflows such as Buddy, research, or error handling.
+- Handles building routing tables, default edges, and condition evaluation logic from declarative definitions.
+- Encourage new graphs to rely on factory functions for consistency and to leverage shared logic.
+
+## Command Patterns & Routing (`command_patterns.py`, `command_routing.py`)
+- `command_patterns.py` defines canonical command names (Continue, Stop, Escalate, etc.) and mapping utilities.
+- `command_routing.py` maps commands emitted by nodes to subsequent edges, ensuring consistent interpretation across workflows.
+- Useful for command-driven flows where user or system actions specify the next step.
+- Update command pattern definitions when introducing new command categories to keep routing in sync.
+
+## Workflow Routing (`workflow_routing.py`)
+- Encapsulates high-level routes for standard workflows (planning, execution, synthesis, adaptation).
+- Provides mapping from workflow phases to node targets, factoring in state flags like `needs_adaptation`.
+- Reused in multiple graphs (Buddy, research) to ensure consistent flow transitions across domains.
+- Extend this module when designing new workflow phases to centralize routing logic.
+
+## Flow Control (`flow_control.py`)
+- Contains helpers for pausing, resuming, or rerouting flows based on state conditions (e.g., rerun, skip, retry).
+- Offers constructs for branching merges, concurrency management, and manual overrides.
+- Use these utilities when building custom flow controls to avoid duplicating complex logic in graphs.
+
+## Secure Routing (`secure_routing.py`)
+- Implements routing checks that enforce security or compliance constraints (preventing unsafe transitions).
+- Integrates with validation modules to ensure workflow transitions respect configured policies.
+- Expand security rules here when new compliance requirements arise.
+
+## Monitoring (`monitoring.py`)
+- Tracks routing decisions, emits telemetry (counts, latencies), and provides diagnostic utilities for debugging routing behavior.
+- Integrate with observability stack to visualize routing patterns and detect anomalies.
+- Extend monitoring when adding new routers or metrics to maintain coverage.
+
+## User Interaction (`user_interaction.py`)
+- Facilitates routing decisions involving user input, approvals, or human-in-the-loop checkpoints.
+- Contains helpers to map user responses to routing actions while preserving audit trails.
+- Update when expanding UI-driven workflows requiring stateful routing logic.
+
+## Validation (`validation.py`)
+- Validates edge definitions, ensuring required fields exist, targets are reachable, and condition expressions are well-formed.
+- Should run whenever new routing definitions are introduced to catch misconfigurations early.
+- Add validation rules when expanding routing capabilities to maintain high-quality workflows.
+
+## Error Handling Support (`error_handling.py`)
+- Provides routing helpers tailored to error recovery flows (e.g., choosing retry vs fallback).
+- Integrates with `biz_bud.core.errors` to align routing decisions with error severity and namespaces.
+- Use these functions when designing error subgraphs to ensure consistent handling across workflows.
+
+## Buddy Router (`buddy_router.py`)
+- Specialized router for Buddy agent workflows, including default routes, conditional edges, and integration with planner/adaptation logic.
+- Serves as reference for building complex routers with multi-phase transitions (planning → executing → analyzing → synthesizing).
+- Update when Buddy workflow phases change to keep agent routing accurate.
+
+## Documentation (`edges.md`)
+- Documents canonical edge naming conventions, routing patterns, and guidelines for adding new edges.
+- Reference this file before defining new transitions to maintain consistency and avoid naming collisions.
+
+## Usage Patterns
+- Build routers via factory functions or dedicated modules rather than hardcoding edges in graphs.
+- Define routing rules declaratively (list of `RoutingRule`s) to keep configuration expressive and easy to audit.
+- Leverage validation helpers to verify routing definitions during CI or startup to catch misconfigurations early.
+- Instrument routing with monitoring helpers to gain insight into decision patterns and bottlenecks.
+- For command-driven flows, map commands through `command_routing` to prevent branching logic duplication.
+
+## Testing Guidance
+- Unit-test routers by instantiating them with test states and asserting outputs from `route` functions.
+- Validate rule priority ordering to ensure specific rules override more general ones as intended.
+- Test command patterns to confirm new commands map to expected targets without regression.
+- Include integration tests for graphs that rely on complex routing trees to verify end-to-end behavior.
+- Monitor coverage of validation utilities to ensure misconfigurations trigger friendly errors.
+
+## Operational Considerations
+- Document routing changes and notify graph owners to prevent unexpected behavior shifts in production.
+- Track routing metrics to identify unexpected loops, dead-ends, or high retry rates indicating workflow issues.
+- Use secure routing helpers to enforce business rules and compliance constraints consistently across workflows.
+- Keep edges documentation current so maintainers and coding agents understand standard patterns before extending them.
+- Ensure routers degrade gracefully when required capabilities or state fields are absent, providing clear error messages.
+
+## Extending Routing Capabilities
+- Create new routing modules when domain-specific logic grows complex (e.g., specialized planner routes) to keep structure modular.
+- Reuse validation and monitoring helpers to maintain consistency and avoid duplicating diagnostic code.
+- Keep command and workflow pattern updates synchronized with clients (e.g., UI or planner) to avoid mismatches.
+- When adding new condition syntax, document it in `edges.md` and update validation to catch errors early.
+- Collaborate with graph owners when introducing new routers to ensure transitions map to real node names and states.
+
+- Final reminder: tag routing maintainers in PRs affecting shared router logic to ensure rigorous review.
+- Final reminder: record routing changes in release notes so downstream teams are aware of behavior updates.
+- Final reminder: run benchmarks if routing logic becomes performance critical (large rule sets).
+- Final reminder: log routing decisions with correlation IDs for easier debugging in distributed environments.
+- Final reminder: revisit this guide quarterly to integrate new best practices and retire outdated advice.

+## Base Exception Hierarchy (`base.py`)
+- Defines `BusinessBuddyError` base class and specialized subclasses (`ConfigurationError`, `ValidationError`, `NetworkError`, `LLMError`, `ToolError`, `StateError`, etc.).
+- Provides enums (`ErrorSeverity`, `ErrorCategory`, `ErrorNamespace`) and context structures (`ErrorContext`) describing error metadata.
+- Implements decorators such as `handle_errors` and `handle_exception_group` to capture and normalize exceptions inside async workflows.
+- Offers helper functions (`create_error_info`, `validate_error_info`, `ensure_error_info_compliance`) to standardize error payloads.
+- Exposes context managers (`error_context`) enabling scoped metadata injection during error capture.
+
+## Error Aggregation (`aggregator.py`)
+- `ErrorAggregator` collects errors, computes fingerprints, tracks counts, and supports rate-limited summaries.
+- `AggregatedError`, `ErrorFingerprint`, and `RateLimitWindow` structures describe aggregated incidents for reporting or throttling.
+- Functions `get_error_aggregator` and `reset_error_aggregator` manage global aggregator instances used by handlers and logs.
+- Aggregation data powers dashboards, alerting, and throttle decisions for noisy error sources.
+
+## Formatting Utilities (`formatter.py`)
+- `ErrorMessageFormatter` transforms error payloads into user-facing or log-friendly messages, including remediation suggestions.
+- Functions `create_formatted_error`, `format_error_for_user`, and `categorize_error` support localization and severity assessment.
+- Extend formatter logic when new namespaces or output channels require tailored formatting.
+
+## Error Handler (`handler.py`)
+- Provides `add_error_to_state`, `create_and_add_error`, `report_error`, `get_error_summary`, `get_recent_errors`, and `should_halt_on_errors` for workflow integration.
+- Updates state objects with structured error metadata, computes summaries, and decides whether execution continues or stops.
+- Works in tandem with aggregator and formatter modules to deliver consistent error experiences.
+- Use handler functions in nodes/graphs to avoid duplicating error state logic and to leverage automatic aggregation.
+
+## LLM Exceptions (`llm_exceptions.py`)
+- Normalizes provider-specific exceptions (timeout, auth, rate limit) into standardized classes (`LLMTimeoutError`, `LLMAuthenticationError`, etc.).
+- Maintains `RETRIABLE_EXCEPTIONS` mapping guiding retry logic in LLM services and nodes.
+- `LLMExceptionHandler` encapsulates detection, backoff decisions, and contextual logging for model invocation failures.
+- Update this module when integrating new LLM providers or error codes to keep classification accurate.
+
+## Logging & Telemetry (`logger.py`, `telemetry.py`)
+- `logger.py` exposes `StructuredErrorLogger`, telemetry hooks, and helpers (`console_telemetry_hook`, `metrics_telemetry_hook`) for consistent logging.
+- `configure_error_logger` sets up logging handlers/formatters capturing context such as thread IDs, namespaces, and severity.
+- `telemetry.py` defines payload schemas and helper functions for emitting structured error events and metrics to observability backends.
+- Integrate these modules to ensure cohesive monitoring of error rates, severities, and remediation outcomes.
+
+## Error Routing (`router.py`, `router_config.py`)
+- `router.py` defines `ErrorRouter`, `RouteAction`, `RouteBuilders`, and condition logic routing errors to actions (retry, fallback, abort, escalate).
+- Supports condition-based routing using fingerprints, namespaces, severity, and custom predicates.
+- `router_config.py` provides `RouterConfig` and helper functions (e.g., `configure_default_router`) to bootstrap routing tables.
+- Extend routing configurations when new error types demand customized handling or when workflows add bespoke recovery paths.
+
+## Tool & Specialized Exceptions (`tool_exceptions.py`, `specialized_exceptions.py`)
+- `tool_exceptions.py` catalogs tool-related exceptions, simplifying error handling in capability integrations.
+- `specialized_exceptions.py` covers domain-specific errors (registry, R2R, security validation, condition security) for precise messaging.
+- Update these modules when introducing new domain components requiring dedicated exception types.
+
+## Types (`types.py`)
+- Defines TypedDicts (`ErrorInfo`, `ErrorDetails`, `ErrorSummary`) and protocols describing structured error payloads used across modules.
+- Keep these definitions synchronized with consumers (state schemas, telemetry payloads, API responses) to avoid drift.
+- Adding fields requires coordination with downstream systems to maintain compatibility.
+
+## Usage Patterns
+- Raise domain-specific exceptions instead of generic ones to leverage routing, formatting, and telemetry automatically.
+- Wrap node functions with `@handle_errors` to centralize error logging and state updates.
+- Invoke `add_error_to_state` where manual error handling is needed, ensuring metadata (`severity`, `category`, `timestamp`) stays consistent.
+- Configure routers during application startup and augment them with domain rules to enforce desired remediation behaviors.
+- Emit telemetry through provided hooks to observe error trends and inform product/ops decisions.
+
+## Testing Guidance
+- Unit-test specialized exceptions to confirm they map to correct categories and severities.
+- Verify formatter outputs produce actionable messages and preserve context (namespace, user-friendly description).
+- Test router rules by passing synthetic `ErrorInfo` objects and asserting the resulting `RouteAction`.
+- Mock telemetry hooks in tests to ensure error events emit proper payloads without hitting external systems.
+- Validate handler integration by simulating errors in sample states and inspecting updated fields (`errors`, `status`).
+
+## Operational Considerations
+- Monitor aggregated errors and routing outcomes to detect recurring issues; tune router actions accordingly.
+- Keep logger configuration aligned with observability requirements (structured fields, tracing IDs).
+- Ensure recovery workflows respect router decisions; mismatches between router actions and node logic can cause loops.
+- Document error namespaces and categories in onboarding materials so contributors can classify new errors correctly.
+- Redact sensitive data in error context (via formatter/handler) to comply with privacy requirements.
+
+## Extending Error Handling
+- Add new exception subclasses in `specialized_exceptions.py` or `tool_exceptions.py` when domain logic requires bespoke handling.
+- Update router configurations and formatter templates alongside new exceptions to maintain cohesive behavior.
+- Expand telemetry payloads with new fields when additional insights are needed; synchronize with downstream analytics.
+- Document new error namespaces in README or design notes so automated systems recognize them.
+- Coordinate with service owners when changing error semantics (severity thresholds, retriable classifications).
+
+- Final reminder: tag error-handling maintainers in PRs touching routing, formatter, or handler modules.
+- Final reminder: capture learnings from incidents in documentation to refine routing and messaging.
+- Final reminder: periodically audit aggregated error data for stale fingerprints that no longer appear.
+- Final reminder: verify telemetry exporters still function after observability stack upgrades.
+- Final reminder: review this guide regularly to incorporate new best practices and retire outdated advice.

+# Directory Guide: src/biz_bud/core/langgraph
+
+## Mission Statement
+- Provide LangGraph integration primitives (node decorators, graph builders, config injection, state safeguards) shared across Business Buddy workflows.
+- Standardize how graphs are constructed, instrumented, and constrained (immutability, logging, metrics).
+- Offer utility modules that graphs and nodes import to maintain consistent behavior across the platform.
+
+## Layout Overview
+- `graph_builder.py` — helper functions for constructing LangGraph `StateGraph`/`Pregel` instances with standardized defaults.
+- `graph_config.py` — configuration utilities and data classes describing graph runtime settings.
+- `runnable_config.py` — helpers for injecting configuration into LangChain/LangGraph `RunnableConfig` objects.
+- `cross_cutting.py` — decorators and wrappers adding logging, metrics, tracing, and timeout behavior to nodes.
+- `state_immutability.py` — safeguards preventing unintended state mutation and providing debugging utilities.
+- `__init__.py` — exports key helpers for convenient import elsewhere in the codebase.
+- `AGENTS.md` (this file) — quick reference for coding agents maintaining LangGraph integration code.
+
+## Graph Builder (`graph_builder.py`)
+- Exposes functions to streamline graph creation: e.g., `create_standard_graph`, wrappers for applying decorators to nodes, utilities to register entry/exit points.
+- Provides helper to attach logging/metrics to entire graph definitions, reducing boilerplate in graph modules.
+- Supports both `StateGraph` (state machine style) and `Pregel` (map-reduce style) patterns used across Business Buddy.
+- Use graph builder when composing new workflows to ensure consistent instrumentation and error handling are applied.
+
+## Graph Configuration (`graph_config.py`)
+- Defines configuration structures and helper functions for graph runtime settings (timeouts, concurrency, retry thresholds).
+- Communicates configuration between service factory, graphs, and nodes, ensuring they share a common view of runtime constraints.
+- Extend this module when introducing new graph-level settings to keep logic centralized.
+
+## Runnable Configuration (`runnable_config.py`)
+- Provides functions (e.g., `inject_config`) to embed `AppConfig` or runtime overrides into `RunnableConfig` objects passed through LangChain/LangGraph.
+- Ensures nodes receive consistent configuration context (API keys, feature flags, toggles) without manually injecting config in each call.
+- Update when configuration schemas change to keep injection logic aligned with available settings.
+
+## Cross-Cutting Concerns (`cross_cutting.py`)
+- Defines decorators/wrappers that add logging, metrics, tracing, timeouts, and error handling to node functions.
+- Examples include `with_logging`, `with_metrics`, `with_timeout`, `with_config` (exact names depend on module content).
+- Apply these decorators in node or graph definitions to standardize cross-cutting behaviors without duplicating code.
+- Extend when new cross-cutting requirements arise (e.g., circuit breakers, feature flag gating).
+
+## State Immutability (`state_immutability.py`)
+- Provides utilities to enforce or check immutability of state dictionaries during node execution.
+- includes functions like `enforce_immutable_state` or context managers highlighting in-place modifications for debugging.
+- Use these utilities to catch unintended state mutations early, preventing hard-to-debug side effects in workflows.
+- Extend when adding new immutability checks or when LangGraph introduces additional state mechanisms.
+
+## Usage Patterns
+- Import graph builder functions when constructing workflows to ensure standard instrumentation is applied consistently.
+- Inject configuration via `runnable_config` helpers rather than manually attaching config to state objects.
+- Wrap nodes with cross-cutting decorators to maintain logging and metrics parity across teams.
+- Run immutability checks during development or debugging to confirm nodes comply with state-handling expectations.
+- Coordinate updates with graph owners whenever cross-cutting behavior changes to avoid surprising runtime differences.
+
+## Testing Guidance
+- Write unit tests for graph builder helpers to ensure they attach expected decorators and configuration to nodes.
+- Validate runnable config injection by asserting nodes receive required config settings in test harnesses.
+- Test cross-cutting decorators (logging, timeout, metrics) with mocks to confirm they trigger expected side effects.
+- Include tests enforcing immutability—simulate nodes attempting in-place mutations and assert warnings/exceptions fire as designed.
+
+## Operational Considerations
+- Document default graph settings and ensure new graphs respect these defaults unless explicitly overridden.
+- Monitor logging/metrics emitted via cross-cutting decorators to verify instrumentation remains functional after updates.
+- Keep immutability enforcement configurable to balance performance with debugging needs (e.g., disable in production if necessary).
+- Align configuration injection with service factory initialization to avoid configuration drift between layers.
+
+## Extending LangGraph Integration
+- When LangGraph releases new features, update builder and config modules first so dependent graphs benefit automatically.
+- Add new decorators in `cross_cutting.py` as cross-cutting needs grow (e.g., distributed tracing, additional telemetry).
+- Expand state immutability utilities when workflows start using new state patterns (e.g., nested dataclasses).
+- Maintain compatibility tests to confirm updates do not break existing graphs or planner integrations.
+
+- Final reminder: tag langgraph integration maintainers in PRs affecting builder or decorator logic to ensure thorough review.
+- Final reminder: synchronize documentation updates with LangGraph dependency bumps so behavior changes are recorded.
+- Final reminder: benchmark performance after introducing new cross-cutting decorators to monitor overhead.
+- Final reminder: revisit this guide periodically to capture emerging best practices and retire outdated instructions.

+# Directory Guide: src/biz_bud/core/networking
+
+## Mission Statement
+- Supply resilient, async-friendly HTTP and API client utilities with standardized retry, concurrency, and typing for Business Buddy services.
+- Provide reusable helpers for network calls, ensuring consistent error handling, telemetry, and configuration across tools and nodes.
+- Define typed request/response contracts to improve static analysis and reduce runtime surprises when integrating external services.
+
+## Layout Overview
+- `http_client.py` — base HTTP client abstractions with async request methods, retry hooks, and response normalization.
+- `api_client.py` — higher-level API client utilities layering authentication, headers, telemetry on top of the HTTP client.
+- `async_utils.py` — concurrency helpers (e.g., `gather_with_concurrency`) for throttled request execution.
+- `retry.py` — retry strategies, backoff policies, and decorators for network resilience.
+- `types.py` — TypedDicts/protocols describing request metadata, response payloads, and client configuration structures.
+- `__init__.py` — exports key networking utilities for convenient imports elsewhere in the codebase.
+- `AGENTS.md` (this file) — contributor guide summarizing modules, functions, and usage patterns.
+
+## HTTP Client (`http_client.py`)
+- Implements async HTTP client class providing methods like `request`, `get`, `post`, `stream` with centralized logging and error handling.
+- Integrates with retry/backoff utilities to handle transient failures gracefully.
+- Supports timeout configuration, headers injection, JSON parsing helpers, and optional instrumentation hooks.
+- Serves as the base for specialized API clients; customize via subclassing or composition.
+- Ensure new services interact through this client to maintain consistent observability and error semantics.
+
+## API Client (`api_client.py`)
+- Builds on the HTTP client, adding authentication, default headers, base URLs, and domain-specific request helpers.
+- Provides reusable methods for JSON APIs (serialize payloads, parse responses) and error normalization (mapping status codes to exceptions).
+- Works in tandem with configuration models to inject API keys, proxies, and timeouts from `AppConfig`.
+- Extend this module when introducing new external APIs to keep credentials and request patterns centralized.
+
+## Async Utilities (`async_utils.py`)
+- Exposes `gather_with_concurrency(limit, *tasks, return_exceptions=False)` controlling concurrency for async operations.
+- Useful for throttling outbound requests (search, scraping) to respect rate limits and avoid overwhelming services.
+- Additional utilities may include cancellation helpers, async context managers, or instrumentation wrappers for network calls.
+- Use these helpers instead of raw `asyncio.gather` when operations need concurrency control or structured error handling.
+
+## Retry Strategies (`retry.py`)
+- Defines backoff policies (exponential, jitter) and decorators to wrap async functions with retry logic.
+- Handles classification of retriable vs non-retriable errors, integrates with logging/metrics for observability.
+- Parameterize retries (max attempts, initial delay) via configuration; align defaults with provider SLAs.
+- Update this module when new provider error patterns emerge requiring tailored retry behavior.
+
+## Types (`types.py`)
+- Provides typed structures for request metadata (method, URL, headers), response objects, and client settings.
+- Maintains Protocols or helper classes enabling dependency injection and testing against typed interfaces.
+- Keep types aligned with client implementations to ensure static analyzers catch mismatches early.
+
+## Usage Patterns
+- Instantiate HTTP/API clients via service factory or dependency injection to reuse configuration and telemetry context.
+- Wrap outbound calls with retry decorators and concurrency helpers for resilience under fluctuating network conditions.
+- Log request metadata (method, URL, correlation IDs) at debug level, redacting sensitive data to aid diagnostics.
+- Use typed responses to validate payload shapes before handing them to downstream processing nodes.
+- Parameterize timeouts and retry counts via `AppConfig` to adjust behavior per environment.
+
+## Testing Guidance
+- Mock HTTP/API clients in unit tests to avoid external calls; verify retries/backoff by simulating error responses.
+- Test concurrency helpers with controlled tasks to confirm limit enforcement and exception propagation behavior.
+- Validate type hints by running static type checkers; update types when payload schemas change.
+- Add integration tests hitting sandbox APIs when feasible to verify end-to-end serialization/deserialization logic.
+
+## Operational Considerations
+- Monitor request metrics (latency, error rates, retry counts) emitted by networking utilities to detect provider issues.
+- Configure proxies or TLS settings via AppConfig and ensure clients respect these settings in all environments.
+- Set sensible default timeouts; avoid leaving them infinite to prevent hung coroutines.
+- Document rate limit policies and align concurrency limits accordingly to avoid service bans.
+- Ensure sensitive headers and payloads are redacted in logs to comply with security requirements.
+
+## Extending Networking Layer
+- Add provider-specific clients in `biz_bud.tools.clients` using these core utilities for HTTP foundations.
+- Introduce new retry/backoff strategies here before wiring them into clients to maintain a single source of truth.
+- Update types and configuration when adding support for new protocols (WebSocket, SSE) or authentication schemes.
+- Collaborate with observability teams when adding new metrics or logging fields to integrate with dashboards and alerts.
+
+- Final reminder: tag networking maintainers in PRs touching HTTP/API clients or retry logic for careful review.
+- Final reminder: benchmark networking changes under load to detect regressions in latency or concurrency handling.
+- Final reminder: revisit this guide periodically as provider requirements evolve and new protocols are adopted.

+# Directory Guide: src/biz_bud/core/url_processing
+
+## Mission Statement
+- Provide shared URL discovery, filtering, configuration, and validation utilities for scraping, ingestion, and search workflows.
+- Centralize heuristics (deduplication, safety checks, normalization) so nodes and capabilities behave consistently across the platform.
+- Offer configurable policies aligned with AppConfig to adapt URL handling per environment or workflow needs.
+
+## Layout Overview
+- `config.py` — configuration models and defaults controlling URL processing behavior (allowed domains, content types, depth limits, blacklist patterns).
+- `discoverer.py` — URL discovery helpers (seed expansion, crawling heuristics) reused by scraping and ingestion workflows.
+- `filter.py` — filtering utilities removing duplicates, applying policy checks, and prioritizing relevant URLs.
+- `validator.py` — validation functions ensuring URLs are syntactically correct, safe, and policy compliant.
+- `__init__.py` — exports helper functions for convenient import elsewhere in the codebase.
+- `AGENTS.md` (this file) — contributor reference for the URL processing subsystem.
+
+## Configuration (`config.py`)
+- Defines configuration data structures (TypedDict/Pydantic) controlling URL policies: allowed schemes, content types, depth, rate limits, blocklists.
+- Provides helper functions to load/validate URL processing config from `AppConfig` or runtime overrides.
+- Ensure new policies (e.g., robots compliance, language filters) are added here to keep configuration centralized.
+
+## Discovery (`discoverer.py`)
+- Implements functions to expand seed URLs, follow sitemaps, or apply heuristics for multi-URL ingestion tasks.
+- Supports batch operations to feed nodes and scraping graphs with candidate URLs derived from initial inputs.
+- Integrate new discovery strategies (RSS parsing, sitemap crawling) here to reuse across workflows.
+
+## Filtering (`filter.py`)
+- Contains filtering logic removing duplicates, excluding blocked domains, and prioritizing URLs based on policy and heuristics.
+- Implements deduplication strategies (e.g., hashed URLs, normalized canonical forms) to prevent redundant processing.
+- Update filters when new criteria (content-type checks, language restrictions, domain scoring) are required.
+
+## Validation (`validator.py`)
+- Provides syntactic and policy validation (`validate_url`, etc.) ensuring URLs meet safety and compliance requirements before processing.
+- Checks include scheme validation, domain whitelists/blacklists, content-type allowances, robots directives (if applicable).
+- Returns structured validation results consumed by nodes and capabilities to inform routing decisions.
+- Extend validation when new policies emerge (e.g., geo restrictions, file size limits).
+
+## Usage Patterns
+- Load URL processing config from `AppConfig` and pass to discover/filter/validate functions for consistent policy enforcement.
+- Use discovery helpers before scraping or ingestion to generate candidate URL lists with policy-aware filtering.
+- Apply filtering functions to deduplicate and prioritize URLs, reducing wasted work downstream.
+- Run validation prior to calling capabilities/tools reliant on external requests to avoid unnecessary network operations.
+- Reuse these helpers in nodes/capabilities rather than duplicating logic to keep policy changes in one place.
+
+## Testing Guidance
+- Write unit tests covering policy scenarios (allowed vs blocked domains, safe vs unsafe schemes).
+- Add regression tests for deduplication logic to ensure canonicalization remains stable as normalization rules evolve.
+- Test discovery heuristics using fixtures mimicking real HTML/sitemap structures to validate expansion behavior.
+- Validate validator outputs (success/failure reasons) to ensure nodes can react appropriately in workflows.
+
+## Operational Considerations
+- Document default policies (allowed domains, depth limits) and ensure operations teams can adjust them via configuration.
+- Monitor URL filtering metrics (accepted vs rejected) to detect policy drift or misconfiguration.
+- Keep blocklists and allowlists updated to reflect compliance requirements and provider constraints.
+- Ensure logging around discovery/filtering redacts sensitive query parameters when necessary.
+
+## Extending URL Processing
+- When new use cases require custom policies, update config schemas and provide clear documentation in README/AGENTS guides.
+- Coordinate with scraping and search capabilities to ensure they honor newly introduced policies or validation outcomes.
+- Integrate telemetry hooks (if needed) to surface URL processing stats in dashboards for analytics and troubleshooting.
+- Keep modules performant; heavy operations (e.g., network-based discovery) should be async and respect concurrency limits.
+
+- Final reminder: tag URL processing maintainers in PRs altering policy logic to guarantee comprehensive review.
+- Final reminder: revisit this guide periodically to capture updated policies and retire outdated examples.

+# Directory Guide: src/biz_bud/core/utils
+
+## Mission Statement
+- Provide reusable utility modules supporting capability inference, state manipulation, graph helpers, URL analysis, lazy loading, and caching across Business Buddy.
+- Centralize helper functions to avoid duplication in nodes, services, and graphs, ensuring consistent behavior and observability.
+- Offer typed utilities that play well with async patterns and the broader core infrastructure (cleanup registry, service factory).
+
+## Layout Overview
+- `capability_inference.py` — infers required tool capabilities based on state/task metadata.
+- `graph_helpers.py` — functions assisting with graph manipulation, cloning, and inspection.
+- `state_helpers.py` — utilities for merging, normalizing, and validating state dictionaries.
+- `message_helpers.py` — helpers for working with conversation/message objects (e.g., LangChain messages).
+- `lazy_loader.py` — async-safe lazy loading and factory management utilities.
+- `cache.py` — lightweight caching helpers (distinct from `core/caching` manager) for memoization within core utils.
+- `regex_security.py` — regex-based sanitization and safety checks (e.g., blocking unsafe patterns).
+- `json_extractor.py` — safe extraction/parsing utilities for JSON content embedded in responses or docs.
+- `url_analyzer.py` & `url_normalizer.py` — helpers analyzing/normalizing URLs to complement `core/url_processing` logic.
+- `__init__.py` — exports public utilities for easy import across the codebase.
+- `AGENTS.md` (this file) — quick reference for the utils package.
+
+## Capability Inference (`capability_inference.py`)
+- Contains logic to deduce which tool/capability families should activate based on state attributes or user queries.
+- Helps planner and agent workflows select appropriate tools without hardcoding capability mappings in multiple places.
+- Update when new capabilities or selection rules are introduced to keep inference accurate.
+
+## Graph Helpers (`graph_helpers.py`)
+- Provides functions to clone graphs, inspect nodes/edges, and instrument workflows programmatically.
+- Useful for debugging, dynamic graph modification, or tooling (e.g., plan visualizations).
+- Extend when new graph manipulation patterns appear to maintain a single source of truth for these operations.
+
+## State Helpers (`state_helpers.py`)
+- Implements safe merge functions, default injection, and convenience accessors for nested state fields.
+- Ensures state dictionaries remain consistent, mitigating KeyError and mutation risks.
+- Update when state schemas evolve to keep helper assumptions aligned with actual structures.
+
+## Message Helpers (`message_helpers.py`)
+- Offers utilities for constructing, normalizing, and trimming conversation messages (e.g., LangChain `HumanMessage`, `AIMessage`).
+- Handles metadata attachment and sanitization to prevent leaking sensitive data in logs or responses.
+- Leverage these helpers in nodes/services dealing with conversational contexts to ensure compatibility with state expectations.
+
+## Lazy Loading (`lazy_loader.py`)
+- Defines `AsyncSafeLazyLoader`, `AsyncFactoryManager`, and related utilities for lazily initializing expensive resources in async contexts.
+- Prevents race conditions by coordinating initialization with locks and weak references to avoid leaks.
+- Extensively used by service factory and cleanup registry; update carefully when altering initialization semantics.
+
+## Cache Helpers (`cache.py`)
+- Provides lightweight caching/memoization helpers separate from the full caching subsystem (quick in-memory caches, decorators).
+- Useful for memoizing small computations inside utils without invoking global cache managers.
+- Ensure caches respect cleanup/TTL requirements to avoid stale data in long-running processes.
+
+## Regex Security (`regex_security.py`)
+- Contains regex patterns and sanitization functions preventing injection or malicious pattern usage.
+- Reused by scraping, validation, and security-sensitive workflows to enforce safe regex operations.
+- Update when new threat patterns are identified or when supporting additional text normalization needs.
+
+## JSON Extraction (`json_extractor.py`)
+- Offers robust JSON parsing/extraction from unstructured content, handling malformed structures and fallback scenarios.
+- Helps nodes/services safely parse JSON embedded in API responses, scraped pages, or logs.
+- Extend with new heuristics or recovery strategies as input sources evolve.
+
+## URL Helpers (`url_analyzer.py`, `url_normalizer.py`)
+- `url_analyzer.py` inspects URLs for features (domain, query params, content hints) used in capability selection or policy decisions.
+- `url_normalizer.py` canonicalizes URLs (e.g., removing tracking params) to improve deduplication and caching.
+- Keep logic in sync with `core/url_processing` modules to maintain cohesive URL handling across the stack.
+
+## Usage Patterns
+- Import these utilities instead of rolling bespoke helpers to maintain consistency and reduce duplication.
+- Document new helper functions with clear docstrings and type hints so automated documentation remains accurate.
+- Register cleanup hooks (where applicable) when helpers manage resources (e.g., caches, lazy loaders).
+- Leverage state/message helpers inside nodes to guarantee compatibility with typed states and conversation structures.
+- Coordinate updates with dependent modules (cores, nodes, tools) when changing utility behavior.
+
+## Testing Guidance
+- Unit-test helpers with representative inputs (state fragments, messages, URLs) to ensure behavior stays deterministic.
+- Validate lazy loader concurrency by simulating parallel initialization attempts in tests.
+- Check regex security functions against known malicious patterns to confirm they block expected cases.
+- Cover JSON extractor fallback paths to ensure malformed inputs yield safe, informative outputs.
+- Keep tests updated when utility functions add new parameters or return shapes to avoid surprises downstream.
+
+## Operational Considerations
+- Monitor logs/timing around lazy loaders to detect initialization bottlenecks or repeated instantiation attempts.
+- Ensure caches and capability inference respect feature flags and configuration toggles to remain environment-aware.
+- Keep regex/security patterns reviewed by security teams when onboarding new content types or sources.
+- Document known limitations (e.g., message trimming thresholds) to help operators interpret agent outputs.
+
+## Extending Core Utilities
+- Add new utility modules when cross-cutting logic emerges; update `__init__.py` to expose them publicly.
+- Follow existing patterns: typed functions, thorough docstrings, and instrumentation/logging where appropriate.
+- Align helper behavior with state and config modules to avoid divergent conventions.
+- Solicit cross-team feedback before altering widely used helpers (state merge logic, lazy loader behavior) to minimize disruptive changes.
+
+- Final reminder: tag core utilities maintainers in PRs affecting shared helpers to guarantee careful review.
+- Final reminder: revisit this guide regularly to capture new utilities and retire outdated helpers.

+# Directory Guide: src/biz_bud/core/validation
+
+## Mission Statement
+- Provide reusable validation utilities ensuring content quality, security, and workflow integrity across Business Buddy.
+- Offer configuration, types, decorators, and processing utilities so nodes and graphs enforce consistent validation policies.
+- Support domain-specific validation (documents, content types, chunking, statistics) and LangGraph configuration verification.
+
+## Layout Overview
+- `base.py` — base classes, helper functions, and shared validation primitives.
+- `config.py` — validation configuration models and defaults (thresholds, enable flags).
+- `content.py`, `content_validation.py`, `content_type.py` — content validation logic, type detection, and policy enforcement.
+- `document_processing.py` — document-level validation helpers (structure, completeness, metadata checks).
+- `chunking.py` — chunking strategies and validation for splitting large documents into manageable sections.
+- `statistics.py` — statistical validation (coverage, duplication metrics) for content and retrieval workflows.
+- `condition_security.py`, `security.py` — security validation ensuring content meets safety requirements (prompt injection, PII detection).
+- `graph_validation.py`, `langgraph_validation.py` — validation utilities for graphs and LangGraph configurations.
+- `decorators.py` — decorators to apply validation steps to nodes or services declaratively.
+- `merge.py` — helper functions for merging validation results and maintaining aggregated views.
+- `examples.py` — example payloads or validation scenarios for documentation and tests.
+- `types.py`, `pydantic_models.py` — typed structures describing validation results, configuration, and detailed findings.
+- `__init__.py` — exports public validation utilities for import convenience.
+- `AGENTS.md` (this file) — contributor reference summarizing modules and usage.
+
+## Base & Config Modules
+- `base.py` defines shared validation functions, result classes, and helper routines used across modules.
+- `config.py` provides configuration models controlling validation behavior (enabled checks, thresholds, severity mappings).
+- Update configuration when introducing new validation policies so callers can toggle behavior via AppConfig.
+
+## Content Validation (`content.py`, `content_validation.py`, `content_type.py`)
+- Implements checks for content quality, completeness, and policy adherence (e.g., profanity filters, sensitive term detection).
+- `content_type.py` detects content type (html, pdf, json) to route validation appropriately.
+- `content_validation.py` orchestrates validation pipelines, producing structured results with severity levels and remediation suggestions.
+- Extend these modules when new content rules emerge or when integrating additional detectors.
+
+## Document Processing (`document_processing.py`)
+- Validates document structure (required sections, metadata, formatting) often used in paperless or extraction workflows.
+- Ensures documents meet ingestion criteria before downstream processing or storage.
+- Update when onboarding new document types or compliance requirements.
+
+## Chunking & Statistics (`chunking.py`, `statistics.py`)
+- `chunking.py` defines chunking strategies (size limits, overlap) and validation ensuring chunks meet length and structure constraints.
+- `statistics.py` computes validation metrics (coverage, duplication, token counts) supporting analytics and quality dashboards.
+- Use these modules when designing RAG ingestion or summarization workflows to maintain data quality.
+
+## Security Validation (`condition_security.py`, `security.py`)
+- Implements security-focused checks (condition security, prompt injection detection, restricted content filters).
+- Integrates with content validation to ensure outputs do not expose sensitive information or violate policies.
+- Extend with new rules when security/compliance teams identify additional risks.
+
+## Graph & LangGraph Validation (`graph_validation.py`, `langgraph_validation.py`)
+- Validates graph configurations, ensuring required nodes/edges exist and metadata meets expectations.
+- Helps catch misconfigured or incomplete workflows before deployment.
+- Update when new workflow patterns or metadata requirements appear.
+
+## Decorators & Merge Utilities (`decorators.py`, `merge.py`)
+- `decorators.py` provides decorators to wrap nodes or services with validation checks, automatically capturing results.
+- `merge.py` merges multiple validation outcomes into consolidated reports, handling severity escalation and deduplication.
+- Use these modules to integrate validation steps seamlessly without manual boilerplate.
+
+## Types & Models (`types.py`, `pydantic_models.py`)
+- Defines typed structures for validation results (`ValidationIssue`, `ValidationSummary`, etc.) and configuration models.
+- Ensure these definitions stay synchronized with consumers (state schemas, API responses) to avoid mismatches.
+- Add new fields cautiously and coordinate changes with dependent modules.
+
+## Usage Patterns
+- Load validation configuration from `AppConfig` and pass to relevant modules to control checks at runtime.
+- Apply validation decorators to nodes handling user-facing or sensitive content to standardize quality control.
+- Combine chunking/statistics helpers to ensure ingestion pipelines maintain expected coverage and duplication tolerances.
+- Use merge utilities to gather results from multiple validation steps into a single state update for downstream processing.
+- Document validation rules so teams understand expectations and can adjust thresholds confidently.
+
+## Testing Guidance
+- Write unit tests covering positive/negative validation scenarios for each module (content, security, chunking).
+- Include representative fixtures (documents, text samples) to ensure validation logic works on real-world inputs.
+- Validate decorators apply checks correctly by wrapping dummy functions and asserting captured results.
+- Cover edge cases such as empty inputs, malformed data, or extreme values to ensure stability.
+
+## Operational Considerations
+- Monitor validation metrics (issue counts, severity distribution) to detect drifts in data quality or policy adherence.
+- Document remediation guidance for high-severity issues so operators know how to respond.
+- Ensure validation results are logged or surfaced to dashboards to inform stakeholders of content quality trends.
+- Balance performance with thoroughness; heavy validation steps may need caching or asynchronous execution to avoid latency spikes.
+
+## Extending Validation
+- Coordinate with domain experts (security, compliance, analysts) when adding new validation rules to capture requirements correctly.
+- Update configuration schemas and README documents when introducing toggles or thresholds for new checks.
+- Keep examples up to date (`examples.py`) to showcase usage patterns for new validations.
+- Synchronize validation state updates with state schemas to reflect new result fields.
+
+- Final reminder: tag validation maintainers in PRs altering core checks to guarantee careful review.
+- Final reminder: revisit this guide periodically to document new validation modules and retire legacy strategies.

+# Directory Guide: src/biz_bud/graphs
+
+## Mission Statement
+- Provide orchestrated LangGraph workflows that compose nodes into end-to-end Business Buddy experiences (analysis, research, RAG ingestion, paperless processing, scraping).
+- Maintain reusable, typed graphs with error handling, human-in-the-loop checkpoints, and configuration-driven routing.
+- Offer factories and utilities so agents can instantiate, cache, or stream graphs without duplicating workflow logic.
+
+## Layout Overview
+- `graph.py` — primary Business Buddy agent graph and caching utilities.
+- `analysis/` — LangGraph workflows for insight generation and visualization.
+- `catalog/` — catalog intelligence workflows with Pregel graphs.
+- `research/` — advanced research graphs with synthesis and validation subflows.
+- `rag/` — URL-to-R2R and URL-to-RAG ingestion workflows with integration hooks.
+- `paperless/` — document processing, receipt handling, and paperless automation graphs.
+- `scraping/` — dedicated scraping graph integrating discovery, routing, and content extraction.
+- `examples/` — sample graphs demonstrating service and research subgraphs.
+- `discord/` — placeholder for Discord-specific workflows (currently minimal).
+- `planner.py` — graph selection, planning orchestration, and planner graph factory.
+- `error_handling.py` — reusable error-handling subgraph composition helpers.
+- `README.md` — conceptual documentation for graph patterns and caching strategies.
+
+## Main Agent Graph (`graph.py`)
+- `create_graph() -> CompiledGraph` builds the core Business Buddy workflow with planning, execution, adaptation, synthesis, and validation phases.
+- `create_graph_with_services(...)` injects service factory dependencies explicitly for advanced scenarios.
+- `create_graph_with_overrides_async(...)` merges runtime overrides and compiles the graph asynchronously.
+- `get_cached_graph()` caches compiled graphs to avoid repeated build cost; cooperates with cleanup registry to evict stale versions.
+- `cleanup_graph_cache()` clears cached graphs (used during hot reloads or configuration changes).
+- `run_graph` / `run_graph_async` convenience wrappers execute the main workflow synchronously or asynchronously, handling configuration loading and error reporting.
+- Graph composition includes planner, executor, analyzer, and synthesizer nodes imported from `biz_bud.nodes` and `biz_bud.agents` packages.
+- Logging and telemetry rely on `biz_bud.core.logging` to provide structured insights (start/end events, adaptation reasons, error summaries).
+- Configuration merges through `AppConfig`; pass overrides via method arguments or `RunnableConfig` to customize behavior.
+- Streaming support surfaces progress updates by yielding intermediate states; clients can subscribe to track long-running tasks.
+
+## Planner & Graph Selection (`planner.py`)
+- `discover_available_graphs() -> dict[str, dict[str, Any]]` enumerates registered graphs with metadata (description, capabilities, prerequisites).
+- `_create_graph_selection_prompt(step, graph_context)` produces prompts guiding LLM-based graph selection logic.
+- `execute_graph_node(state, config)` executes a selected subgraph as part of multi-step plans.
+- `create_planner_graph(config=None)`, `compile_planner_graph()`, `planner_graph_factory`, and `planner_graph_factory_async` build planner-specific workflows to map user intent to appropriate graphs.
+- Planner graphs integrate with capability registries and rely on `StateUpdater` to merge plan outcomes back into parent workflows.
+
+## Error Handling Graph Utilities (`error_handling.py`)
+- `create_error_handling_graph(...)` constructs a subgraph combining error analyzer, guidance, recovery planner, and executor nodes.
+- `add_error_handling_to_graph(graph_builder, config)` injects error handling states into existing graphs, ensuring consistent recovery semantics.
+- `error_handling_graph_factory` / `_async` expose factories for standalone usage or embedding into specialized workflows.
+- Use these utilities when adding new domain graphs to guarantee unified error behavior across the platform.
+
+## Analysis Graphs (`analysis/`)
+- `create_analysis_graph() -> CompiledStateGraph` builds an analysis workflow orchestrating data interpretation, visualization, and summarization nodes.
+- `analysis_graph_factory` (sync/async) exposes LangGraph-compatible factories for API usage.
+- Nodes live in `analysis/nodes` (plan, interpret, visualize); they rely on `biz_bud.nodes` utilities and typed states from `biz_bud.states.analysis`.
+- Designed for business intelligence tasks—graph structure includes branching for data quality checks and advanced visualization requests.
+
+## Catalog Graphs (`catalog/`)
+- `create_catalog_graph() -> Pregel[CatalogIntelState]` leverages LangGraph Pregel to orchestrate catalog intelligence steps (data enrichment, scoring, recommendations).
+- `catalog_graph_factory` wraps graph creation with configuration injection and optional capability filters.
+- Supporting modules `nodes/` and `nodes.py` include typed nodes for catalog research, defaults, and analysis; backup versions illustrate previous iterations.
+- Catalog graphs integrate scoring, market analysis, and structured output creation tailored to product catalogs.
+
+## Research Graphs (`research/`)
+- `create_research_graph(...)` orchestrates research planning, evidence gathering, synthesis, validation, and final reporting.
+- `research_graph_factory` (sync/async) returns compiled graphs ready for agent execution or standalone use.
+- `create_research_graph_async` supports asynchronous setup when graphs require service initialization within event loops.
+- `get_research_graph()` caches compiled versions similar to the main graph for efficiency.
+- Research nodes (prepare, query derivation, synthesis, validation) live under `research/nodes/` and reuse shared states such as `biz_bud.states.research`.
+- The graph supports human feedback injection, streaming insights, and evidence-linked summaries to boost trustworthiness.
+
+## RAG Graphs (`rag/`)
+- `create_url_to_r2r_graph(config=None)` builds ingestion flows that fetch URLs, extract content, deduplicate, and upload to R2R collections.
+- `url_to_r2r_graph_factory` / `_async` produce compiled graphs with runtime overrides for collection names, deduping, and metadata policies.
+- `url_to_rag_graph_factory` orchestrates ingestion into vector stores used by retrieval workflows; adjust config for custom store connections.
+- `integrations.py` wires specialized connectors (e.g., R2R API), and `nodes/` includes modules for batch processing, duplicate checks, upload routines, and scraping subflows.
+- `subgraphs.py` (if present) combines lower-level nodes into modular sequences (document parsing, tagging, search).
+- Use these graphs when onboarding large document sets or refreshing knowledge bases powering downstream agents.
+
+## Paperless Graphs (`paperless/`)
+- `create_paperless_graph(...)` orchestrates OCR, document validation, tagging, and search indexing for paperless workflows.
+- `create_receipt_processing_graph` (direct and factory variants) handles receipt ingestion, classification, and structured output generation.
+- `paperless_graph_factory` / `_async` expose compiled graphs for integration with API endpoints or CLI commands.
+- `subgraphs.py` defines reusable components (`create_document_processing_subgraph`, `create_tag_suggestion_subgraph`, `create_document_search_subgraph`) for modular assembly.
+- Graphs coordinate with `biz_bud.nodes.extraction`, `validation`, and `tools.capabilities.document` to perform high-fidelity document processing.
+
+## Scraping Graph (`scraping/graph.py`)
+- `create_scraping_graph()` constructs a workflow focused on URL discovery, routing, scraping, extraction, and deduplication.
+- Factory functions (`scraping_graph_factory`, `_async`) supply preconfigured compiled graphs for use by orchestrators or CLI tools.
+- Graph integrates discovery nodes, caching, batching, and extraction steps to produce structured scraped datasets.
+- Use this graph standalone for large scraping jobs or embed it within RAG and paperless pipelines for ingestion pre-processing.
+
+## Examples (`examples/`)
+- Contains educational scripts like `human_feedback_example.py` and `service_factory_example.py` showcasing how to instantiate graphs programmatically.
+- Useful for onboarding: replicate patterns here when designing new custom graphs or debugging factory usage.
+
+## Discord (`discord/`)
+- Currently hosts initialization scaffolding; expand this directory when adding Discord-specific workflows or bots.
+- Keep placeholder updated or remove once real graphs are implemented to avoid confusion.
+
+## README.md
+- Documents graph design principles, caching strategies, configuration layers, and sample usage patterns.
+- Sync this file with updates made in `AGENTS.md` to provide consistent guidance to human contributors.
+
+## Usage Patterns
+- Import compiled graphs via factories (`analysis_graph_factory`, `research_graph_factory`, etc.) to ensure configuration and logging policies apply uniformly.
+- Pass runtime overrides through `RunnableConfig` or explicit parameters so graphs adapt to per-request requirements (collections, feature flags, thresholds).
+- Utilize streaming variants for long-running tasks; they surface incremental progress and mitigate timeouts.
+- Combine graphs sequentially by feeding structured outputs from one into the next (e.g., research -> analysis -> synthesis).
+- Leverage planner and discovery utilities to route user requests automatically to the best workflow.
+
+## Configuration & Services
+- Graphs rely on `AppConfig` for service endpoints, feature flags, and model choices; ensure configs stay synchronized with environments.
+- Service access flows through `biz_bud.services.factory`; initialize required services prior to invoking graphs in standalone contexts.
+- Error handling integration expects `biz_bud.core.errors` routers to be configured; confirm routes cover new error types introduced by domain graphs.
+- For new graphs, register cleanup hooks with the cleanup registry so cached graphs and service instances release resources gracefully.
+
+## Testing Guidance
+- Unit-test graphs using LangGraph’s `Pregel` or `CompiledGraph` test utilities, mocking external services to ensure determinism.
+- Integration tests should invoke graph factories end-to-end with representative state payloads, verifying outputs, streaming events, and error handling.
+- Use `pytest-asyncio` to exercise async graph factories and streaming flows; ensure event loop cleanup between tests.
+- Validate planner selection logic by injecting synthetic step metadata and verifying graph choices via `discover_available_graphs`.
+- Keep regression tests for caching behavior (`get_cached_graph`) to confirm invalidation and rebuild logic functions as expected.
+
+## Operational Considerations
+- Monitor graph build times; caching reduces startup cost but requires periodic invalidation when configuration or code changes.
+- Track adaptation counts and error recovery metrics to detect systemic issues in workflows.
+- Ensure streaming outputs remain backward compatible; client SDKs may expect specific event shapes.
+- When adding new graphs, update registry metadata and planner prompts so automated selection stays accurate.
+- Document prerequisites (API keys, indices, feature flags) required by specialized graphs to avoid deployment surprises.
+
+## Extending Graph Ecosystem
+- Start by defining typed states in `biz_bud.states`, then assemble nodes from `biz_bud.nodes` before introducing custom edges or subgraphs.
+- Reuse error-handling and planner utilities to maintain consistent user experiences across workflows.
+- Add metadata to `discover_available_graphs` so new graphs show up in capability discovery and introspection responses.
+- When bridging to external systems, encapsulate interactions in nodes or services rather than inside graph definitions to preserve modularity.
+- Document new graphs here and in README to guide coding agents and human contributors alike.
+
+- Keep graph factories pure; avoid side effects beyond configuration validation and logging.
+- Register cleanup tasks for graph-specific caches (e.g., planner cache) via `cleanup_graph_cache` patterns.
+- Align RAG graph collection naming with infrastructure conventions to simplify monitoring.
+- Coordinate planner prompt updates with prompt engineering teams to maintain selection quality.
+- Run load tests on scraping and RAG graphs before large ingestion campaigns to calibrate concurrency.
+- Capture benchmark metrics (build time, execution latency) after major graph refactors to evaluate improvements.
+- Gate experimental graphs behind configuration flags to opt-in gradually.
+- When duplicating graph structures for new domains, extract shared subgraphs into helper modules to avoid drift.
+- Ensure new graph states include telemetry fields (timestamps, step durations) critical for monitoring.
+- Update documentation and onboarding guides with new graph capabilities to inform stakeholders.
+- Sync releases with data governance teams when graphs export or persist new types of data.
+- Verify that graph-level retries harmonize with node-level recovery to prevent redundant work.
+- Maintain compatibility with LangGraph version updates; run smoke tests when bumping dependencies.
+- Store designer diagrams or Mermaid charts illustrating new graphs for quick comprehension.
+- Leverage `examples/` to prototype subgraphs before integrating them into production workflows.

+# Directory Guide: src/biz_bud/nodes
+
+## Mission Statement
+- Provide reusable LangGraph node functions that encapsulate IO, LLM, search, scraping, extraction, validation, and error-recovery behavior for Business Buddy workflows.
+- Maintain stateless, composable primitives that mutate only declared portions of the state and delegate heavy lifting to shared services.
+- Ensure every node inherits instrumentation, logging, and error semantics from `biz_bud.core.langgraph` by using the established decorator stack.
+
+## Directory Layout
+- `__init__.py` lazily re-exports canonical nodes so graphs can import from `biz_bud.nodes` without tight coupling.
+- `core/` contains foundational nodes for payload parsing, response formatting, persistence, and error escalation.
+- `llm/` manages model invocations, message preparation, transcript updates, and exception categorization.
+- `search/` orchestrates multi-provider web search with ranking, deduplication, caching, and monitoring helpers.
+- `scrape/` implements batched scraping plus route selection for different extraction strategies.
+- `url_processing/` discovers, filters, and validates URLs before scraping or ingestion.
+- `extraction/` runs semantic extraction pipelines, orchestrating chunking, embeddings, and entity recognition.
+- `validation/` verifies outputs, handles human feedback loops, and enforces business rules.
+- `error_handling/` supplies analyzer, guidance, interceptor, and recovery nodes to stabilize workflows under failure.
+- `integrations/` holds thin wrappers for external provider-specific settings (currently Firecrawl).
+
+## Core Node Highlights (`core/`)
+- `parse_and_validate_initial_payload(state, config) -> dict` normalizes incoming payloads, applies schema checks, and seeds initial state dictionaries.
+- `format_output_node(state, config) -> dict` constructs base response envelopes before channel-specific formatting occurs.
+- `prepare_final_result(state, config) -> dict` merges summaries, key points, and metadata into the structure expected by callers.
+- `format_response_for_caller(state, config) -> dict` adapts responses for API, CLI, or streaming contexts while preserving citations.
+- `persist_results(state, config) -> dict` writes outputs to configured storage layers (Postgres, blob stores) and records persistence status.
+- `handle_graph_error(state, config) -> dict` captures exceptions, produces `ErrorDetails`, and routes recovery behavior in cooperation with `biz_bud.core.errors`.
+- `handle_validation_failure(state, config) -> dict` records validation issues, downgrades severity when appropriate, and triggers fallback flows.
+- `preserve_url_fields_node(state, config) -> dict` copies `url` and `input_url` forward to maintain provenance across nodes.
+- `finalize_status_node(state, config) -> dict` stamps terminal status fields, sets `is_last_step`, and attaches timing metrics.
+- Implementation Pattern: each node imports helpers from `biz_bud.core.helpers` for redaction and respects the `StateUpdater` partial-update contract.
+
+## LLM Node Highlights (`llm/`)
+- `call_model_node(state, config) -> dict` invokes the configured LLM provider via the service factory, handling retries, throttling, and telemetry.
+- `prepare_llm_messages_node(state, config) -> dict` builds LangChain message lists, injects system prompts, and merges conversation history.
+- `update_message_history_node(state, config) -> dict` appends assistant outputs to conversation state, enforcing history limits, anonymization, and redaction.
+- Supporting helpers `_categorize_llm_exception`, `handle_llm_invocation_error`, and `handle_unexpected_node_error` map provider errors into standardized categories for routing.
+- `NodeLLMConfigOverride` dataclass allows nodes to override model names, temperatures, or token limits per invocation without mutating global config.
+- Design Tip: always pass `RunnableConfig` into LLM nodes so they can adjust timeouts and trace IDs based on upstream configuration.
+
+## Search Node Highlights (`search/`)
+- `web_search_node(state, config) -> dict` executes multi-provider search, composes optimized queries, and returns ranked results with citations.
+- `research_web_search_node(state, config) -> dict` tailors search to research workflows, coordinating domain weighting and depth heuristics.
+- `cached_web_search_node(state, config) -> dict` wraps `web_search_node` with Redis-backed caching to avoid redundant provider calls.
+- `optimized_search_node(state, config) -> dict` orchestrates query optimization and distribution across providers while respecting concurrency limits.
+- `deduplication.py` exposes `DeduplicationService` classes for cosine, MinHash, and SimHash strategies; nodes import these to collapse near-duplicates.
+- `ranker.py` implements `rank_and_deduplicate` with freshness scoring, domain diversity, and semantic similarity checks.
+- `query_optimizer.py` classifies queries, extracts entities, selects providers, and merges related queries to minimize cost.
+- `cache.py` provides `SearchCache` helpers for generating cache keys, tracking hits, and warming caches ahead of heavy workloads.
+- `monitoring.py` tracks search performance metrics, exposes recommendations, and supports periodic metric resets for dashboarding.
+- `search_orchestrator.py` batches search tasks, monitors provider health, applies circuit breakers, and handles retries or fallbacks.
+
+## Scrape Node Highlights (`scrape/` & `url_processing/`)
+- `discover_urls_node(state, config) -> dict` seeds URL lists using configured discovery strategies and respects domain/robots policies.
+- `route_url_node(state, config) -> dict` selects the appropriate scraping strategy (simple fetch, headless browser, Firecrawl) based on URL metadata.
+- `scrape_url_node(state, config) -> dict` fetches pages, applies content extraction pipelines, and records scraping telemetry.
+- `batch_process_urls_node(state, config) -> dict` processes multiple URLs concurrently, merging results and preserving input order.
+- `url_processing/_typing.py` offers coercion helpers (`coerce_str`, `coerce_bool`, etc.) to sanitize configuration inputs for URL nodes.
+- `process_urls_node(state, config) -> dict` orchestrates discovery, filtering, and validation steps before scraping commences.
+- `validate_urls_node(state, config) -> dict` verifies format, deduplicates, and filters URLs against blocklists, returning structured validation results.
+- Integration Note: nodes call out to `biz_bud.core.url_processing` functions, guaranteeing shared logic for deduplication and policy checks.
+
+## Extraction Node Highlights (`extraction/`)
+- `extract_key_information_node(state, config) -> dict` performs rule-based extraction, entity mapping, and scoring for structured outputs.
+- `semantic_extract_node(state, config) -> dict` combines embeddings, LLM summarization, and semantic selectors to extract insights from documents.
+- `orchestrate_extraction_node(state, config) -> dict` coordinates chunking, asynchronous tool calls, and result merging into a unified payload.
+- `extractors.py` merges LLM extraction results, manages concurrency via semaphores, and normalizes scoring metadata.
+- `consolidated.py` handles document chunking, entity detection, and chunk scoring; reuse these helpers when expanding extraction flows.
+- `semantic.py` integrates with the service factory to obtain embedding clients and normalizes multimodal content before processing.
+- `orchestrator.py` exposes `extract_key_information` with skip logic for disallowed URLs or unsupported MIME types.
+- Contract: nodes return keys like `extracted_info`, `sources`, and `confidence_scores` to keep synthesizer expectations consistent.
+
+## Validation Node Highlights (`validation/`)
+- `validate_content_output(state, config) -> dict` enforces business rules, fact checks, and style guidelines on generated content.
+- `identify_claims_for_fact_checking(state, config) -> dict` extracts statements requiring verification and queues them for fact-check tools.
+- `perform_fact_check(state, config) -> dict` invokes fact-check workflows, merges evidence, and annotates state with verdicts.
+- `validate_content_logic(state, config) -> dict` verifies logical consistency in plans or arguments, flagging contradictions for remediation.
+- `human_feedback_node(state, config) -> dict` decides whether to request reviewer input, packages feedback requests, and applies feedback when returned.
+- `prepare_human_feedback_request(state, config) -> dict` structures payloads for human review portals, attaching context and confidence data.
+- `apply_human_feedback(state, config) -> dict` integrates reviewer suggestions, records provenance, and updates the state with refinement outcomes.
+- Helper functions such as `should_request_feedback` and `should_apply_refinement` read config-driven thresholds—tune them in configuration, not node code.
+
+## Error Handling Node Highlights (`error_handling/`)
+- `error_analyzer_node(state, config) -> dict` classifies errors by namespace, type, and severity, producing remediation recommendations.
+- `user_guidance_node(state, config) -> dict` generates user-facing messages explaining the issue, recovery steps, and preventive measures.
+- `error_interceptor_node(state, config) -> dict` intercepts errors before they escalate, merging context from prior nodes and deciding response modes.
+- `recovery_planner_node(state, config) -> dict` selects recovery actions—retry, fallback, skip—and updates plan metadata accordingly.
+- `recovery_executor_node(state, config) -> dict` executes chosen recovery actions with exponential backoff, fallback handlers, or workflow aborts.
+- Support functions (`_execute_recovery_action`, `_retry_with_backoff`, `_execute_fallback`) guarantee consistent logging and state updates for each action.
+- `register_custom_recovery_action(name, action)` lets integrators extend recovery catalogues without editing core logic.
+- Analyzer helpers parse error strings to distinguish LLM, config, tool, network, validation, rate limit, and auth scenarios; keep regex lists current.
+
+## Integrations (`integrations/firecrawl/`)
+- `load_firecrawl_settings(state, config) -> dict` loads provider-specific settings (API keys, concurrency, fallbacks) and injects them into state before scraping nodes run.
+- Place additional provider-specific configuration loaders here to keep nodes thin and configuration centralized.
+
+## Lazy Export Registry (`__init__.py`)
+- `_EXPORTS` maps friendly names to module paths, allowing graphs to import nodes via `from biz_bud.nodes import web_search_node`.
+- `__getattr__` lazily imports modules, caches fetched callables, and avoids circular import issues.
+- Update `_EXPORTS` whenever you add or rename a canonical node so downstream code stays consistent.
+
+## Usage Patterns
+- Nodes should always return partial dictionaries; LangGraph merges them with existing state immutably.
+- Accept `config: RunnableConfig | None` and read overrides (`config.get("config")`) to honor per-run adjustments.
+- Fetch services through `biz_bud.services.factory.get_global_factory()` to reuse initialized clients and caches.
+- Propagate telemetry identifiers like `thread_id` and `run_metadata` when logging or calling services for traceability.
+- Guard any optional keys using `.get()` or helper functions from `biz_bud.core.utils.state_helpers` to avoid `KeyError`.
+
+## Extensibility Guidelines
+- Model new nodes after existing patterns: async function, thin logic, decorators for logging/error handling, and docstrings describing expected state inputs/outputs.
+- Extend `AppConfig` and override structures when adding configuration flags; avoid hardcoding constants inside nodes.
+- Update typed state definitions (`biz_bud.states`) when introducing new state keys and keep `BuddyStateBuilder` or other builders aligned.
+- Place provider-specific logic in `biz_bud.tools.capabilities` and call those helpers from nodes to avoid duplication.
+- Document new node behavior in this guide so coding agents reference it instead of replicating functionality.
+
+## Testing Guidance
+- Use pytest async tests with representative state fixtures to confirm node outputs and error behavior.
+- Mock external services (LLM, Firecrawl, Tavily) by stubbing service factory methods to isolate node logic.
+- Verify recovery nodes by injecting synthetic `ErrorDetails` and asserting planned actions match expectations.
+- Run integration tests covering LLM, search, scraping, extraction, and validation nodes after structural changes to ensure end-to-end stability.
+- Track coverage for this package; nodes form the majority of runtime logic and benefit from high test coverage.
+
+## Diagnostics & Telemetry
+- Use structured logs (`logger.info`/`logger.debug`) with node names, phases, and capability identifiers for easier filtering in observability tools.
+- Emit timing metrics around external calls to detect latency regressions quickly.
+- Inspect `state.run_metadata` or `state.metrics` fields to understand cross-node timing data when debugging slow executions.
+- Leverage `search/monitoring.py` outputs to monitor cache hit rates, provider performance, and recommendation summaries.
+- Remember to adjust dashboards when adding new metrics or changing existing metric names.
+
+## Coding Agent Tips
+- Search this directory before writing new code; many helpers already exist for common needs (query optimization, deduplication, error routing).
+- Maintain naming consistency (`*_node`) so registries and documentation remain intuitive.
+- Avoid mutating shared objects or using globals; rely on state copies and the cleanup registry for shared resources.
+- When returning errors, set `last_error` and detail fields to aid recovery planners and synthesizers.
+- For configuration-heavy nodes, read overrides from `state["config"]` first, then fall back to global config to support per-request tuning.
+
+## Operational Considerations
+- Keep nodes idempotent; LangGraph may re-run them during retries or recovery sequences.
+- Control concurrency with semaphores or `gather_with_concurrency` to avoid overwhelming external providers.
+- Prevent blocking operations inside nodes; delegate CPU-heavy work to threads or subprocesses when necessary.
+- Document environment dependencies (API keys, feature flags) referenced by nodes to simplify onboarding.
+- Monitor cache utilization (search, extraction) to tune TTLs and prevent stale data from affecting results.
+
+## Maintenance Playbook
+- Update `_EXPORTS` and this guide whenever nodes are added, removed, or renamed to keep documentation accurate.
+- Keep docstrings descriptive; automated tooling reads them to populate contributor prompts and docs.
+- Coordinate with graph owners before changing node signatures or returned fields to avoid runtime breakage.
+- Align tests, schemas, and configuration docs with node updates to avoid drift across layers.
+- Run `make test` and targeted CLI demos after modifying core nodes to validate end-to-end workflows.
+
+## Improvement Opportunities
+- Consolidate overlapping URL discovery logic once classifier experiments conclude.
+- Expand validation nodes with adversarial prompt detection using `biz_bud.core.validation.security`.
+- Explore response caching within `call_model_node` for deterministic prompts to reduce cost.
+- Add telemetry correlation for human feedback loops to track reviewer impact.
+- Provide type stubs for newly exported nodes to enhance static analysis in downstream projects.
+
+- Reference `biz_bud.nodes.NODES.md` for historical patterns before drafting experimental nodes.
+- Propagate trace IDs from `state.run_metadata` when calling services so distributed traces remain connected.
+- Document new plan markers in extraction nodes to keep synthesizer expectations aligned.
+- Wrap blocking libraries with `asyncio.to_thread` so event loops remain responsive.
+- Align scrape route decisions with `state.available_capabilities` to avoid invoking unavailable tools.
+- Update error router mappings when introducing new exception categories to keep guidance accurate.
+- Review cache TTLs for search results periodically to balance freshness and efficiency.
+- Ensure recovery actions remain idempotent to prevent compounding side effects.
+- Provide graceful fallbacks when providers are unreachable to maintain user trust.
+- Annotate new return payloads with TypedDict definitions for clarity and static checking.
+- Audit environment variable usage annually to remove deprecated keys from setup scripts.
+- Balance instrumentation verbosity with performance; heavy logging in tight loops can inflate costs.
+- Maintain compatibility with Python versions listed in `pyproject.toml`; avoid version-specific syntax.
+- Coordinate extraction schema changes with RAG teams to maintain downstream compatibility.
+- Produce notebooks or playground scripts demonstrating new node behavior for reviewers.
+- Expose new telemetry metrics via existing monitoring modules for consistency.
+- Keep recovery action names descriptive for telemetry dashboards and alerting.
+- Update nodes that read `state.tool_selection_reasoning` when capabilities change names.
+- Encourage contributors to run `make lint-all` before submitting node changes to catch type issues early.
+- Track per-node latency metrics to identify hotspots after deployments.
+- Align cache invalidation logic across services when adjusting caching strategies.
+- Review TODO markers quarterly and convert them into tracked backlog items.
+- Capture incident retrospectives involving nodes and incorporate lessons into this document.
+- Keep fixtures in `tests/fixtures` synchronized with node expectations to avoid brittle tests.
+- Validate streaming responses remain consistent when nodes update `state.extracted_info` incrementally.
+- Check provider rate limits before increasing concurrency defaults in search or scraping nodes.
+- Publish migration notes when deprecating nodes so downstream teams can transition smoothly.
+- Encourage experimentation in feature branches; merge only thoroughly tested node changes into main.
+- Collaborate with tooling teams to share adapters rather than duplicating integration logic here.
+- Closing note: align new node metrics with existing Grafana panels before deploying.
+- Closing note: share architecture updates in the weekly agent sync so all contributors stay informed.
+- Closing note: record semantic version bumps when node signatures change to aid downstream consumers.
+- Closing note: verify docs and notebooks illustrate updated node behaviors after major refactors.
+- Closing note: keep onboarding materials pointing to these guides to help new agents ramp quickly.
+- Closing note: tag maintainers in PRs that modify high-risk nodes (LLM, search, extraction).
+- Closing note: snapshot benchmark results before and after performance improvements for posterity.
+- Closing note: archive deprecated nodes in a `legacy/` folder only temporarily; remove them once migrations finish.
+- Closing note: practice feature-flagging experimental nodes to limit blast radius during trials.
+- Closing note: coordinate incident reviews when nodes contribute to outages and capture remediation items here.
+- Closing note: ensure staging environments mirror production configuration when validating node updates.

+# Directory Guide: src/biz_bud/services
+
+## Mission Statement
+- Provide managed service abstractions (LLM clients, vector stores, semantic extraction, databases, web tools) for Business Buddy workflows.
+- Centralize lifecycle, configuration, and cleanup logic so nodes and graphs can request services without duplicating setup code.
+- Offer factories, registries, and helper utilities that enforce consistent logging, monitoring, and dependency injection across the stack.
+
+## Layout Overview
+- `factory/` — service factory implementation (`service_factory.py`) and related helpers.
+- `factory.py` — high-level factory API exporting `ServiceFactory`, `get_global_factory`, and initialization helpers.
+- `base.py` — base service classes, lifecycle hooks, and typed interfaces.
+- `container.py` — service container definitions for dependency injection and scope management.
+- `singleton_manager.py` — orchestrates singleton service initialization with async-safety and health checks.
+- `logger_factory.py` — provides logging configuration for services.
+- `redis_backend.py`, `db.py` — foundational backend abstractions for cache and database connectivity.
+- `vector_store.py`, `semantic_extraction.py`, `web_tools.py` — domain-specific service modules built on top of base classes.
+- `llm/` — LLM service configuration, clients, types, utilities.
+- `MANAGEMENT.md` and `README.md` — documentation guiding service lifecycle best practices.
+- `AGENTS.md` (this file) — quick reference for coding agents.
+
+## Core Service Interfaces (`base.py`)
+- Defines abstract base classes for services, including initialization, health checks, and cleanup contracts.
+- Establishes typing aliases (`ServiceInitResult`, `ServiceHealthStatus`) used across factory and cleanup code.
+- Provides mixins for telemetry integration so derived services emit consistent metrics.
+- Extend these base classes when building new services to ensure compatibility with the factory and singleton manager.
+
+## Service Factory Ecosystem (`factory/` & `factory.py`)
+- `factory/service_factory.py` implements `ServiceFactory`, responsible for creating, caching, and cleaning up service instances.
+- `ServiceFactory` integrates with the cleanup registry, ensures thread/async safety, and centralizes dependency injection.
+- Supports domains such as LLM, search, vector stores, web tools, extraction, and telemetry services.
+- `factory.py` exports convenience functions (`get_global_factory`, `initialize_factory`, etc.) used across agents and graphs.
+- Global factory pattern ensures service reuse and prevents repeated setup cost; nodes should call `get_global_factory()` instead of instantiating services directly.
+- Factory methods return typed services (LLMService, VectorStoreService, SemanticExtractionService); consult module docs for capabilities.
+
+## Singleton Manager (`singleton_manager.py`)
+- Manages singleton lifecycle with async locking, health checks, and weak references to prevent memory leaks.
+- Works in tandem with the cleanup registry (in `biz_bud.core`) to guarantee proper teardown on shutdown or reload.
+- Provides helper methods like `ensure_service_initialized`, `cleanup_all`, and health check routines invoked by the service factory.
+- When adding new service categories, ensure singleton manager knows how to track their health and cleanup hooks.
+
+## Containers & Dependency Management (`container.py`)
+- Defines service containers grouping related dependencies (e.g., analysis services, data services).
+- Allows selective startup/shutdown operations by container, improving control over resource usage.
+- Container metadata informs monitoring and debugging tools about service compositions.
+
+## Logging & Telemetry (`logger_factory.py`)
+- Supplies logging configuration tailored for services, ensuring consistent log formats across different service modules.
+- Integrates with structured logging from `biz_bud.logging` to propagate correlation IDs and context.
+- Services should obtain loggers via this module instead of direct `logging.getLogger` calls.
+
+## Backend Utilities
+- `redis_backend.py` implements Redis-based storage primitives used for caching, state retention, or rate limiting.
+- `db.py` provides database helpers (connection pooling, query utilities) used by analytics or metadata services.
+- These modules abstract low-level backend operations so services can focus on domain logic.
+
+## Domain-Specific Services
+- `vector_store.py` wraps vector database interactions (e.g., Qdrant, Pinecone) with standardized methods for insert, query, and maintenance.
+- `semantic_extraction.py` provides services coordinating embedding models, extraction pipelines, and scoring logic.
+- `web_tools.py` bundles web automation services (e.g., browser sessions) for reuse across scraping and extraction workflows.
+- Extend these modules when introducing new domains; keep logic encapsulated so nodes/graphs only call service interfaces.
+
+## LLM Services (`llm/`)
+- `client.py` exposes classes for interacting with configured LLM providers (OpenAI, Anthropic, etc.) with streaming and error handling support.
+- `config.py` defines typed configuration models (model names, temperature, timeouts) referenced by service factory and nodes.
+- `types.py` declares service interfaces, payload schemas, and response formats for LLM operations.
+- `utils.py` provides helper functions (prompt building, response normalization) shared across service methods.
+- LLM services integrate with caching, retry logic, and telemetry hooks to provide resilient inference experiences.
+
+## Module Summaries
+- `web_tools.py` provides high-level wrappers that orchestrate web interactions beyond simple scraping (e.g., form submissions).
+- `semantic_extraction.py` coordinates extraction engines, using capabilities from `biz_bud.tools` and providing service-level caching.
+- `vector_store.py` surfaces methods for creating collections, upserting vectors, querying neighbors, and managing metadata.
+- `redis_backend.py` exports Redis connection helpers, serialization routines, and TTL management functions used by caching services.
+- `db.py` includes connection pooling utilities and query helpers to support analytics and catalog services.
+
+## Documentation (`README.md`, `MANAGEMENT.md`)
+- README covers service design philosophy, lifecycle management, and usage examples; keep it updated alongside this guide.
+- MANAGEMENT.md provides operational instructions (start/stop, dependency installation) for maintainers managing service infrastructure.
+- Review these files when onboarding new contributors or adjusting service orchestration strategies.
+
+## Usage Patterns
+- Retrieve services via `get_global_factory()`; avoid manual instantiation to benefit from caching and cleanup integration.
+- When running tests, use factory initialization helpers to inject mocks or test doubles for services.
+- Services should log initialization and cleanup actions, enabling observability into runtime behavior.
+- Store configuration overrides in `AppConfig` and pass them to factory methods; do not hardcode credentials or endpoints inside services.
+- Use service scopes (if provided) to limit resource usage and shut down unneeded services in long-running sessions.
+
+## Testing Guidance
+- Write unit tests for service modules using pytest fixtures to mock external dependencies (LLM APIs, databases, vector stores).
+- Validate singleton manager behavior (initialization, health checks, cleanup) to prevent resource leaks in production.
+- Ensure service factory tests cover both synchronous and asynchronous factory methods, including override scenarios.
+- Use integration tests to confirm services interact correctly with clients defined in `biz_bud.tools.clients`.
+- Include regression tests for caching and retry strategies to maintain reliability during provider outages.
+
+## Operational Considerations
+- Register cleanup hooks with the cleanup registry for every service category to ensure graceful shutdowns.
+- Monitor service health via exposed metrics; integrate with dashboards tracking error rates, latency, and resource usage.
+- Rotate credentials on a defined schedule; service modules should read secrets from environment variables to simplify rotation.
+- When scaling horizontally, ensure singleton manager configuration avoids cross-process state where inappropriate.
+- Document dependency versions (SDKs, drivers) and test upgrades in staging before deploying to production.
+
+## Extending the Service Layer
+- Define a new service class deriving from `BaseService`, implement `ainit`, `cleanup`, and domain-specific methods.
+- Register the service in `ServiceFactory`, update configuration schemas, and add cleanup hooks to the registry.
+- Provide typed interfaces and utils similar to existing modules to maintain developer ergonomics.
+- Update tooling (capabilities, nodes) to consume the new service via factory methods rather than direct instantiation.
+- Document new services in README, MANAGEMENT, and this guide to maintain discoverability.
+
+## Collaboration & Communication
+- Coordinate with infrastructure teams when services depend on external infrastructure (databases, caches, vector stores).
+- Notify graph and node owners when service signatures or initialization requirements change.
+- Capture design decisions in architecture notes or ADRs when introducing impactful service patterns.
+- Share performance benchmarks after optimizing service initialization or request handling to highlight improvements.
+- Ensure runbooks include service-specific diagnostic steps (e.g., checking Redis, verifying vector store connectivity).
+
+- Final reminder: maintain parity between staging and production service configs to avoid drift.
+- Final reminder: tag service owners in PRs touching shared factory code to guarantee review.
+- Final reminder: audit service logs periodically to confirm redaction of sensitive data.
+- Final reminder: align monitoring alerts with service health checks exported by singleton manager.

+# Directory Guide: src/biz_bud/states
+
+## Mission Statement
+- Provide typed state definitions for LangGraph workflows, ensuring strong typing, validation, and documentation across agents, graphs, and nodes.
+- Encapsulate workflow-specific fields (analysis, research, RAG, paperless, search) and common fragments shared across modules.
+- Offer helper modules for composing focused state subsets, merging defaults, and exposing consistent schemas to downstream tooling.
+
+## Layout Overview
+- `base.py` — foundational TypedDicts and base classes for states, including metadata and error fields.
+- `common_types.py` — reusable components (timestamps, provenance, confidence scores) shared across states.
+- `domain_types.py` — domain-specific fragments (financial metrics, catalog attributes) used to compose larger states.
+- `focused_states.py` — curated subsets for specialized tasks (e.g., short-lived flow segments).
+- `unified.py` — unified state compositions for cross-cutting use cases.
+- Workflow modules: `analysis.py`, `research.py`, `catalog.py`, `market.py`, `buddy.py`, `search.py`, `extraction.py`, `validation.py`, `feedback.py`, `reflection.py`, `receipt.py`, `tools.py`, `planner.py`, etc.
+- RAG-specific modules: `rag.py`, `rag_agent.py`, `rag_orchestrator.py`, `url_to_rag.py`, `url_to_rag_r2r.py`.
+- `error_handling.py` — states dedicated to error capture, recovery, and human guidance flows.
+- `validation_models.py` — Pydantic models supporting validation states and schema enforcement.
+- `catalogs/` — subdirectory with catalog-focused state definitions (modular components).
+
+## Base & Common Modules
+- `base.py` defines `BaseState` and mixins for metadata such as timestamps, status flags, context objects, and error tracking.
+- Includes fields for `run_metadata`, `errors`, `messages`, and convenience flags like `is_last_step` to coordinate workflow endings.
+- `common_types.py` provides shared TypedDicts (for example, `DocumentChunk`, `SourceInfo`, `ConfidenceScore`) reused across workflows.
+- `domain_types.py` captures domain-specific pieces such as catalog items, market metrics, and research evidence structures.
+- `focused_states.py` defines subsets for targeted operations (e.g., `CapabilityState`, `ContentReviewState`) to reduce duplication when composing new states.
+- `unified.py` aggregates multiple fragments into canonical states, making it easier to reference complex workflows from a single import.
+
+## Workflow States
+- `analysis.py` — supports analytic workflows (insights, charts, metrics) with fields for analysis plans, visualization requests, and data snapshots.
+- `research.py` — captures research steps including questions, evidence, synthesis artifacts, validation status, and summary outputs.
+- `catalog.py` and `catalogs/` — specialized states for catalog intelligence (catalog entries, enrichment metadata, scoring results).
+- `market.py` — market research state definitions (competitor data, market trends, demand indicators).
+- `buddy.py` — main Buddy agent state containing orchestration phase, plan, execution history, adaptation flags, and introspection data.
+- `search.py` — search workflow states (query metadata, provider results, ranking stats, deduplication outputs).
+- `extraction.py` — extraction states (extracted info, chunk metadata, semantic scores, embeddings).
+- `validation.py` — validation states capturing rule results, content flags, fact-check outcomes, and severity levels.
+- `feedback.py` — human feedback request/response structures, review statuses, rationale fields.
+- `reflection.py` — reflective states for iterative improvement (insights, improvements, action items).
+- `receipt.py` — receipt processing states (line items, totals, vendor metadata, confidence).
+- `tools.py` — state fragments describing tool usage, capability selection reasons, runtime stats, and logging context.
+- `planner.py` — planning states used by graph selection and plan execution workflows.
+- `error_handling.py` — error context states including error type, severity, remediation steps, and human guidance outputs.
+
+## RAG & Ingestion States
+- `rag.py` — base state for RAG ingestion (document collections, chunk metadata, retrieval settings, deduplication markers).
+- `rag_agent.py` — specialized RAG agent state capturing conversation context, retrieved evidence, follow-up questions, and summarization outputs.
+- `rag_orchestrator.py` — orchestrator-focused state with ingestion progress, deduplication counters, and completion flags.
+- `url_to_rag.py` and `url_to_rag_r2r.py` — pipeline states for URL ingestion, including fetch summaries, extraction logs, upload status, and error tracking.
+- Keep these states in sync with graphs in `biz_bud.graphs.rag` and capabilities in `biz_bud.tools` to avoid mismatches.
+
+## Catalog Subdirectory (`catalogs/`)
+- Houses modular catalog components (e.g., `m_components.py`, `m_types.py`) for building composite catalog states.
+- Use these modules when constructing new catalog workflows to maintain uniform schema across services and graphs.
+
+## Validation Models (`validation_models.py`)
+- Pydantic models backing validation states; enforce stricter typing for content review and QA pipelines.
+- Synchronize with TypedDict definitions to keep runtime validation and static typing expectations aligned.
+
+## README & Documentation
+- README explains state layering patterns, composition practices, and safe extension strategies; keep it updated alongside this guide.
+- Document examples of state composition in README to help contributors extend workflows correctly.
+
+## Usage Patterns
+- Import state definitions in nodes and graphs to obtain type hints and official documentation for expected fields.
+- Compose states using `TypedDict` inheritance and helper mixins rather than redefining keys in multiple modules.
+- When mutating state, rely on helper functions (`biz_bud.core.utils.state_helpers`) to maintain type safety and immutability expectations.
+- Document new fields with descriptive comments; automated documentation uses these notes to inform coding agents.
+- Keep states cohesive by factoring shared fields into common modules; avoid large catch-all states with unrelated data.
+
+## Extending State Schemas
+- Define new fragments in `common_types.py` or `domain_types.py` when fields are reusable across workflows.
+- For workflow-specific additions, modify the relevant module and annotate fields with docstrings describing purpose and expected values.
+- Update builders (e.g., `BuddyStateBuilder`) and nodes that rely on new fields to prevent runtime errors.
+- Coordinate with service and capability owners to ensure data produced/consumed by states remains aligned.
+- Add tests verifying schema integrity (TypedDict keys, default values) to catch accidental regressions early.
+
+## Testing & Validation
+- Use static type checkers (basedpyright, pyrefly) to confirm modules import the correct state definitions.
+- Write unit tests that instantiate states and pass them through serialization/deserialization pipelines to ensure compatibility with Pydantic models.
+- Update fixtures in `tests/fixtures` when states change to keep integration tests reflective of current schemas.
+- Assert in node tests that required fields are present before execution to catch schema drift quickly.
+- Ensure API schemas or OpenAPI docs referencing states are regenerated after schema changes to avoid contract mismatches.
+
+## Operational Considerations
+- Version state schemas or maintain migration notes when introducing breaking changes; communicate updates broadly to dependent teams.
+- Maintain backward compatibility or provide migration utilities when renaming/removing fields to avoid downtime.
+- Document default values and fallback behaviors so operators understand initialization flows under various contexts.
+- Align state changes with analytics dashboards; update dashboards and data pipelines when schemas evolve.
+- Periodically audit states for unused or legacy fields and remove them to reduce cognitive load.
+
+## Collaboration & Communication
+- Notify graph, node, and service owners when state schemas change so they can adapt logic and data transformations.
+- Review new state definitions with data governance or security teams if sensitive identifiers or PII-related fields are introduced.
+- Capture schema evolution in changelogs or ADRs to maintain historical context for future maintainers.
+- Share sample payloads demonstrating new fields to accelerate adoption by other teams.
+- Keep this guide and README updated together to prevent conflicting instructions for contributors and coding agents.
+
+- Final reminder: run type checkers after editing states to surface missing imports or mismatched fields early.
+- Final reminder: coordinate state schema changes with analytics and reporting teams to keep dashboards accurate.
+- Final reminder: ensure serialization layers respect new fields and redaction requirements.
+- Final reminder: update builder utilities whenever state defaults shift to avoid inconsistent initialization.
+- Final reminder: archive older schema versions when long-lived workflows still reference them.
+- Final reminder: validate streaming payloads against updated state schemas after modifications.
+- Final reminder: evaluate memory footprint when expanding states to avoid excessive serialization costs.
+- Final reminder: involve QA reviewers when state changes impact user-facing summaries or UI logic.
+- Final reminder: tag state maintainers in PRs to guarantee thorough schema reviews.
+- Final reminder: revisit this guide quarterly to retire outdated advice and highlight new best practices.

+# Directory Guide: src/biz_bud/tools
+
+## Mission Statement
+- Provide tool abstractions that graphs and nodes can invoke via capability registries: browsing, extraction, search, document processing, workflow orchestration.
+- Encapsulate external integrations (Tavily, Firecrawl, Paperless, Jina, R2R) behind consistent interfaces and configuration models.
+- Offer utility modules (loaders, HTML helpers, shared models) that keep tool implementations DRY and type-safe.
+
+## Layout Overview
+- `capabilities/` — grouped tool families (batch, database, document, extraction, fetch, introspection, scrape, search, url_processing, workflow, etc.).
+- `browser/` — headless browser abstractions and helpers used by scraping nodes and capabilities.
+- `clients/` — provider-specific API clients (Firecrawl, Tavily, Paperless, Jina, R2R) with shared auth and retry logic.
+- `loaders/` — resilient content loaders (e.g., web base loader) shared by tools and nodes.
+- `utils/` — HTML utilities and shared helper functions for tool responses.
+- `interfaces_module.py` — registries and base interfaces linking capabilities to the agent runtime.
+- `models.py` — Pydantic models defining capability metadata, tool descriptors, and response shapes.
+- `README.md` — high-level overview of tool design patterns and usage instructions.
+
+## Capability Architecture (`capabilities/`)
+- Each subdirectory exports capability factories, metadata, and provider implementations conforming to common interfaces.
+- Capabilities integrate with the agent via registries declared in `capabilities/__init__.py`, which exposes discovery and loader functions.
+- Tools rely on typed configuration objects and validators defined in `models.py` to enforce consistency across providers.
+- When adding new capabilities, create a subdirectory with provider modules, update registries, and document behavior in this guide.
+
+### Batch (`capabilities/batch/`)
+- `receipt_processing.py` batches receipt-related operations (parsing, enrichment) for higher throughput in paperless workflows.
+- Exposes capability descriptors that RAG and paperless graphs consume to process receipt datasets efficiently.
+
+### Database (`capabilities/database/`)
+- `tool.py` wraps database-oriented operations (query, insert, summarization) behind a consistent tool interface.
+- Use this when connecting to structured data stores; extend with provider-specific implementations as needed.
+
+### Document (`capabilities/document/`)
+- `tool.py` exposes document-processing utilities (OCR, tagging) leveraged by paperless and extraction workflows.
+- Built to integrate with document stores and supports metadata tagging outputs compatible with search/indexing services.
+
+### External (`capabilities/external/`)
+- `__init__.py` registers connectors to third-party platforms (Paperless, etc.).
+- `paperless/tool.py` provides Paperless-specific operations (search, upload, tagging) packaged as Business Buddy capabilities.
+- Add other external connectors here to separate integration logic from domain-specific nodes.
+
+### Extraction (`capabilities/extraction/`)
+- Modular design with subpackages: `core`, `numeric`, `statistics_impl`, `text`, plus helper modules (`content.py`, `legacy_tools.py`, `receipt.py`, `structured.py`).
+- `core/base.py` defines base extraction classes and type hints that other extraction providers implement.
+- `numeric/` delivers numeric extraction and quality assessment tools suited for receipts and financial data.
+- `statistics_impl/` adds statistical extraction routines (averages, variance) to support analytics nodes.
+- `text/structured_extraction.py` handles structured text extraction tasks, converting unstructured documents into typed outputs.
+- `single_url_processor.py` and `semantic.py` orchestrate extraction workflows for single documents or semantic contexts.
+
+### Fetch (`capabilities/fetch/`)
+- `tool.py` standardizes remote content retrieval operations, wrapping HTTP clients with retry and normalization behavior.
+- Use this capability when nodes require low-level fetch logic outside of full scraping workflows.
+
+### Introspection (`capabilities/introspection/`)
+- `tool.py` and `interface.py` expose runtime introspection (capability listing, graph discovery) for meta-queries.
+- `models.py` defines response formats shown to users when they request agent capability summaries.
+- `providers/default.py` implements the default introspection provider; extend with specialized providers if needed.
+- README explains how to extend introspection features without duplicating logic within agent nodes.
+
+### Scrape (`capabilities/scrape/`)
+- `tool.py` and `interface.py` provide scraping orchestration, handling concurrency, result normalization, and error mapping.
+- `providers/` includes connectors for `beautifulsoup`, `firecrawl`, and `jina`; each implements provider-specific scraping strategies.
+- Extend this capability when adding new scraping engines; ensure providers expose consistent method signatures for nodes.
+
+### Search (`capabilities/search/`)
+- `tool.py` describes how search requests are orchestrated across providers and how responses map back to state.
+- `providers/` folder implements connectors for `arxiv`, `jina`, `tavily`, enabling multi-provider search ensembles.
+- The capability integrates ranking, deduplication, and caching; reuse it rather than invoking providers directly from nodes.
+
+### URL Processing (`capabilities/url_processing/`)
+- `service.py`, `interface.py`, and `models.py` wrap URL normalization, deduplication, validation, and discovery services.
+- `providers/` implement deduplication, normalization, discovery, and validation logic compatible with scraping and ingestion workflows.
+- Keep configuration (thresholds, blocklists) centralized here to maintain consistent URL handling across graphs.
+
+### Workflow (`capabilities/workflow/`)
+- Contains orchestration helpers (`execution.py`, `planning.py`, `validation_helpers.py`) used by Buddy agent and planner nodes.
+- Tools in this family generate execution records, convert intermediate results, and format responses (`ResponseFormatter`).
+- Extend these helpers when adding new plan or synthesis behaviors to ensure consistent data structures across workflows.
+
+### Other Capability Folders
+- `capabilities/discord/` is ready for future Discord tooling; populate once chat integrations need specialized commands.
+- `capabilities/utils/` reserved for cross-capability helpers; keep it tidy by deleting unused placeholders as the ecosystem evolves.
+
+## Browser Abstractions (`browser/`)
+- `base.py` defines base classes for browser sessions, including context managers and navigation helpers.
+- `browser.py` implements standard headless browser interactions, managing lifecycle and error handling.
+- `driverless_browser.py` offers an alternative implementation for driverless scraping scenarios.
+- `browser_helper.py` hosts utility functions for screenshotting, DOM extraction, and navigation consistency.
+- Nodes and capabilities import these classes to avoid recreating Selenium or Playwright boilerplate.
+
+## Clients (`clients/`)
+- `firecrawl.py` wraps the Firecrawl API, handling auth, concurrency limits, and response normalization.
+- `paperless.py` interacts with Paperless-ngx or related platforms for document ingestion and retrieval.
+- `tavily.py` integrates with Tavily search APIs, including tracing and configuration overrides.
+- `jina.py` provides access to Jina search or embedding services used in search/scrape workloads.
+- `r2r.py` and `r2r_utils.py` implement ingestion and collection management for R2R-based retrieval systems.
+- Clients expose typed methods consumed by capabilities and nodes; they should remain thin wrappers focused on API concerns.
+
+## Loaders (`loaders/`)
+- `web_base_loader.py` provides resilient web content loading with retries, throttling, and HTML normalization.
+- Used by scraping and extraction workflows to standardize raw content fetching before downstream processing.
+
+## Utilities (`utils/`)
+- `html_utils.py` sanitizes, prettifies, and extracts structured data from HTML snippets; capabilities rely on it for consistent output.
+- Keep shared helper functions here to avoid scattering HTML or text normalization logic across capabilities.
+
+## Interfaces & Models
+- `interfaces_module.py` centralizes capability registration, providing functions for loading capability sets and mapping agent requests to tools.
+- `models.py` contains Pydantic models describing capability metadata, tool descriptors, provider settings, and invocation payloads.
+- When introducing new capability types, extend models first so validation and serialization stay consistent across the stack.
+
+## Usage Patterns
+- Capabilities expose callable tool objects; nodes retrieve them via capability registries instead of instantiating clients directly.
+- Configuration flows from `AppConfig` into capability-specific settings; respect typed models when customizing behavior at runtime.
+- Clients manage auth and retries; avoid embedding API logic inside nodes or graphs to keep concerns separated.
+- HTML utilities and loaders should be reused rather than duplicated in capability modules to maintain consistent parsing behavior.
+- Document new tools in `README.md` and this guide so agents understand available capabilities and prerequisites.
+
+## Testing Guidance
+- Mock external APIs (Firecrawl, Tavily, Jina) using client classes; inject test doubles to keep unit tests deterministic.
+- Validate capability registration by importing `biz_bud.tools.capabilities` and asserting new tools appear in discovery outputs.
+- Write integration tests for complex capabilities (workflow execution) that cover execution records, response formatter outputs, and error paths.
+- Use fixtures representing provider responses to ensure parsing logic in clients and utilities remains stable over time.
+- Run contract tests for models to confirm serialization/deserialization works with real-world payloads.
+
+## Operational Considerations
+- Secure API keys via environment variables; clients read them during initialization—document required variables for each provider.
+- Monitor rate limits and adjust capability concurrency settings accordingly to prevent provider lockouts.
+- Track error rates per capability; integrate with telemetry dashboards to identify brittle providers quickly.
+- Evaluate dependency updates (e.g., Firecrawl SDK versions) in staging before production rollout.
+- Coordinate with security teams when capabilities handle sensitive documents; apply redaction or encryption helpers as needed.
+
+## Extensibility Guidelines
+- When adding a capability, define configuration models, implement provider logic, register the capability, and update discovery metadata.
+- Keep provider modules small; delegate shared behavior (HTTP requests, retries) to client classes to prevent code duplication.
+- Document limitations (rate limits, unsupported content types) within tool docstrings so agents can plan fallbacks.
+- Update state schemas or node expectations when capabilities change response shapes to avoid runtime KeyErrors.
+- Use feature flags or configuration toggles to enable new capabilities gradually across environments.
+
+## Collaboration & Communication
+- Notify graph and node owners when capabilities change—downstream workflows may need adjustments or additional validation.
+- Align capability naming with discovery prompts so the planner and introspection responses remain accurate.
+- Keep README and this guide in sync; human contributors rely on both for onboarding and troubleshooting.
+- Share sample payloads or notebooks demonstrating capability usage to accelerate adoption by other teams.
+- Review capability changes with security/privacy stakeholders when handling regulated data to ensure compliance.
+
+- Final reminder: verify logging includes capability names and provider IDs for observability.
+- Final reminder: add metric labels for new tools to track usage and success rates.
+- Final reminder: retire unused capability folders promptly to avoid confusion.
