feat(flow): add source-free transport indexing - #219
Conversation
Retain transport inventory and unresolved source-boundary descriptors without materializing source files. Strict checkout remains fail-closed, while CLI and MCP expose the explicit index-only operation.

Merge Risk: 🔵 Low · up to Indexing preserves existing source files, but an indexing failure can expose raw diagnostic details to MCP clients. Sanitize those error responses before merging or accept this bounded risk. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new operation is confined to the existing workspace and uses the existing write authorization class. It does not materialize source files, and later checkout rejects its incomplete descriptors as a complete checkout. Concurrent operations on the same repository may still interfere with metadata and rollback; that failure-containment question is not fully resolved. Retained concerns

The implementation correctly adds source-free transport indexing functionality. The code properly reuses existing manifest classification logic, maintains type safety, handles errors appropriately, and follows established patterns. No defects found that block merge.
You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.

Fixed in 3d58774. The flow_index_tr parity test now lives in the existing tests/integration.test.ts entrypoint; vitest.config.ts is restored to its pre-PR scope, so no legacy MCP tests are excluded.

Fixed in 3d58774. Indexing now creates a source-free FlowContext that validates only the registered format; strict checkout alone requires materialize. Regression coverage verifies an inventory-only format produces descriptors with zero source reads.
