Make sure the change is safe to apply." + +**Expected Tool Sequence**: +1. `smp_locate("validate_input", node_types=["Function"])` $\rightarrow$ Find the target function in `api.py`. +2. `smp_impact("validate_input", "modify")` $\rightarrow$ Identify all callers to understand the blast radius. +3. `smp/session/open(agent_id, task="refactor validate_input", scope=["api.py"], mode="write")` $\rightarrow$ Acquire a write session on the target file. +4. `smp/guard/check(session_id, target="validate_input")` $\rightarrow$ Check for hot-node status, zero-coverage flags, or active locks. Abort if `verdict == "red_alert"`. +5. `smp/dryrun(session_id, file_path="api.py", proposed_content=refactored_code)` $\rightarrow$ Perform structural impact assessment on the proposed change. +6. `smp/checkpoint(session_id, files=["api.py"])` $\rightarrow$ Snapshot state before writing. +7. `smp/update(file_path="api.py", content=new_code, change_type="modified")` $\rightarrow$ Sync the updated graph after the write. +8. `smp/session/close(session_id, status="completed")` $\rightarrow$ Release the session. + +**Success Criteria**: The LLM follows the full session lifecycle without skipping the guard or dryrun steps. It correctly aborts if the guard returns a blocking verdict. + +--- + +## Scenario 6: Runtime vs. Static Call Discrepancy +**Question**: "Static analysis shows `api.py` does not directly call `auth_check` in `Integration.java`, but we're seeing it in production traces. How is this possible, and which runtime path triggers it?" + +**Expected Tool Sequence**: +1. `smp_locate("auth_check")` $\rightarrow$ Find the function node in `Integration.java`. +2. `smp_navigate("auth_check", include_relationships=True)` $\rightarrow$ Inspect edges; note absence of `CALLS_STATIC` from `api.py`. +3. `smp_trace("auth_check", relationship="CALLS_RUNTIME")` $\rightarrow$ Follow only runtime edges to find the DI-injected or metaprogramming-resolved caller chain. +4. `smp_context("api.py")` $\rightarrow$ Inspect the file for dynamic dispatch patterns (e.g., a plugin registry or decorator) that static analysis would miss. +5. `smp_flow("api_module", "auth_check", edge_type="CALLS_RUNTIME")` $\rightarrow$ Confirm the full runtime execution path. + +**Success Criteria**: The LLM distinguishes between `CALLS_STATIC` and `CALLS_RUNTIME` edges, correctly identifies the dynamic dispatch mechanism, and explains why static analysis alone is insufficient. + +--- + +## Scenario 7: Hot Node Identification and Test Gap Analysis +**Question**: "Before we start the next sprint, which functions are most risky to change? We want to know what's both frequently called and poorly tested." + +**Expected Tool Sequence**: +1. `smp/telemetry/hot(window_days=30)` $\rightarrow$ Retrieve nodes with high heat scores (high churn + high PageRank). +2. `smp_navigate("hot_node_function")` $\rightarrow$ For each hot node, inspect its relationships. +3. `smp/guard/check(target="hot_node_function")` $\rightarrow$ Check for test coverage flags; a `red_alert` verdict confirms zero or weak coverage. +4. `smp_trace("hot_node_function", relationship="TESTS", depth=1)` $\rightarrow$ Find existing test nodes, if any, to assess coverage quality. +5. `smp_context("test_file.py")` $\rightarrow$ Inspect the test implementation to determine if assertions are meaningful or tautological. + +**Success Criteria**: The LLM produces a ranked list of high-risk functions with an explanation of their heat score, call depth, and test coverage status. It does not attempt to modify any hot node without first addressing the test gap. + +--- + +## Scenario 8: Multi-Agent Conflict Detection +**Question**: "Two agents are assigned tasks that both require editing `core.rs`. Agent A is refactoring `serialize_payload` and Agent B is optimizing `deserialize_payload`. Will they conflict?" + +**Expected Tool Sequence**: +1. `smp_locate("serialize_payload")` $\rightarrow$ Find node for Agent A's target. +2. `smp_locate("deserialize_payload")` $\rightarrow$ Find node for Agent B's target. +3. `smp/plan(tasks=[task_A, task_B])` $\rightarrow$ Submit both planned edits to the SMP planner. +4. `smp/conflict(session_ids=[session_A, session_B])` $\rightarrow$ Detect overlapping file scopes, shared dependencies, or structural coupling between the two functions. +5. `smp_navigate("shared_dependency")` $\rightarrow$ If a conflict is found, inspect the shared node (e.g., a common `PayloadSchema` struct) to understand the coupling. +6. `smp/session/open(..., mode="mvcc")` $\rightarrow$ If no hard conflict, open MVCC sessions so both agents can proceed in parallel isolated sandboxes. + +**Success Criteria**: The LLM correctly identifies whether a hard conflict exists. If it does, it proposes serialization of the tasks. If it does not, it opens MVCC sessions rather than unnecessarily blocking one agent. + +--- + +## Scenario 9: Sandbox Execution and Integrity Verification +**Question**: "Agent A has written new tests for `calculate_metrics` in `core.rs`. Verify that the tests are meaningful and not tautological before merging." + +**Expected Tool Sequence**: +1. `smp_locate("calculate_metrics")` $\rightarrow$ Find the target function node. +2. `smp_trace("calculate_metrics", relationship="TESTS")` $\rightarrow$ Find all test nodes linked to the function. +3. `smp/sandbox/spawn(base_commit=current_sha)` $\rightarrow$ Spawn an ephemeral microVM with a CoW copy of the codebase. +4. `smp/sandbox/execute(sandbox_id, command="pytest tests/test_core.rs")` $\rightarrow$ Run the test suite inside the sandbox to confirm baseline pass. +5. `smp/verify/integrity(sandbox_id, target="calculate_metrics")` $\rightarrow$ Run the two-gate integrity check: (a) AST data-flow check to confirm `assert()` receives function output; (b) mutation testing to confirm surviving mutants are zero. +6. `smp/sandbox/destroy(sandbox_id)` $\rightarrow$ Tear down the ephemeral environment after verification. + +**Success Criteria**: The LLM does not skip the integrity gate. It correctly interprets surviving mutants as a test failure and reports that the tests must be tightened before the merge is approved. + +--- + +## Scenario 10: Community Boundary and Architecture Drift Detection +**Question**: "Our architecture review flagged that the `api.py` module seems to be calling functions deep inside what should be the data layer's private implementation. Is this an actual architecture violation?" + +**Expected Tool Sequence**: +1. `smp_locate("api.py", node_types=["File"])` $\rightarrow$ Find the file node and its `community_id`. +2. `smp/community/get(community_id="comm_api_gateway")` $\rightarrow$ Get the community definition, centroid, and declared boundaries. +3. `smp_trace("api_function", relationship="CALLS_STATIC", depth=4)` $\rightarrow$ Follow the call chain from `api.py` into the data layer. +4. `smp/community/boundaries(source_community="comm_api_gateway", target_community="comm_data_layer")` $\rightarrow$ Check if any traversed nodes belong to the data layer's fine-grained community and whether the `BRIDGES` relationship is declared or undeclared. +5. `smp_navigate("undeclared_bridge_node")` $\rightarrow$ Inspect the offending cross-community call to confirm the violation. + +**Success Criteria**: The LLM correctly uses community membership (`MEMBER_OF`, `BRIDGES`) to distinguish a declared inter-community interface from an undeclared internal coupling. It reports the specific functions breaching the boundary. + +--- + +## Scenario 11: Incremental Index Sync After a Batch Commit +**Question**: "A developer just pushed a commit that modified 40 files across the Python and Rust layers.

More precise than semantic search. +- **Use Case**: "Find the `UserSession` class" or "Locate all functions named `validate_token`." +- **Parameters**: + - `query` (string): The name or pattern to search for. + - `node_types` (list[string], optional): Filter by type (e.g., `["Class", "Function"]`). +- **Returns**: A list of matching entities. + +#### `smp_navigate` +Explores the relationships around a starting point. +- **Use Case**: "What does the `PaymentGateway` class depend on?" or "What calls the `process_order` function?" +- **Parameters**: + - `query` (string): The starting entity name or ID. + - `include_relationships` (bool): Whether to return the edges connecting to other nodes. +- **Returns**: The starting node and its immediate neighborhood in the structural graph. + +--- + +### 2. Deep Analysis & Context + +#### `smp_context` +Extracts the structural and semantic context for a specific file. +- **Use Case**: "I need to see the imports and class definitions in `auth_service.py` to understand how it's structured." +- **Parameters**: + - `file_path` (string): Path to the file. + - `scope` (string): `edit` (local), `read` (moderate), or `full` (entire file). +- **Returns**: A structured view of the file's contents and its role in the project. + +#### `smp_trace` +Traces a chain of dependencies or calls across multiple levels. +- **Use Case**: "Trace the call path from the API endpoint `/login` down to the database query." +- **Parameters**: + - `start` (string): The starting entity ID/name. + - `relationship` (string): The edge type to follow (e.g., `CALLS`, `DEFINES`). + - `depth` (int): How many levels to trace (1-10). +- **Returns**: A path of entities and relationships. + +#### `smp_flow` +Finds a path between two specific entities. +- **Use Case**: "How does data flow from the `UserRequest` object to the `DatabaseWriter`?" +- **Parameters**: + - `start` (string): Starting entity. + - `end` (string): Ending entity. + - `flow_type` (string): The type of flow (e.g., `data`, `control`). +- **Returns**: The shortest path between the two entities. + +--- + +### 3. Modification & Impact + +#### `smp_impact` +Analyzes what would happen if an entity were changed or deleted. +- **Use Case**: "If I rename the `calculate_tax` function, which other parts of the system will break?" +- **Parameters**: + - `entity` (string): The entity to analyze. + - `change_type` (string): `modify` or `delete`. +- **Returns**: A list of affected entities (the "blast radius"). + +#### `smp_update` +Updates the codebase and the knowledge graph. +- **Use Case**: "Refactor the `calculate_tax` function to support VAT" or "Add a new method to the `User` class." +- **Parameters**:
