Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Personal-scope project searches can generate follow-up guidance that looks for results in the wrong scope, causing users to see no matching memories even when personal matches exist.

- Line 2257: Expand the tests around mem_find_project beyond tool registration
by invoking its handler with deterministic fixtures. Cover a successful search
result, missing query, invalid match_mode, no results, and store failures,
asserting each response and error behavior; keep the existing registration
assertion intact.
In `@internal/mcp/mcp.go`:
- Line 1199: Update the result formatting in the mem_find_project output around
TopRank so nearby computed ranks remain distinguishable and the returned value
preserves sufficient numeric precision; replace the fixed two-decimal formatting
in the fmt.Fprintf call with a precision-preserving representation while keeping
the existing project and match-count fields unchanged.
In `@internal/store/store_test.go`:
- Around line 8834-8906: Expand TestSearchProjects to cover empty queries,
any-mode matching, exclusion of deleted or blank-project observations,
zero/limited result bounds, query-error propagation, and deterministic TopRank
ordering. Use the existing test store and search-related helpers to create each
scenario, assert expected results and errors, and retain the current all-mode
grouping assertions.

Assert the relevance-ordering contract.
The PR requires mem_find_project to return projects ordered by relevance. These tests can pass if the store returns the wrong top project or the MCP handler reverses the ordered results.

All CodeRabbit feedback has been addressed. The formatting fix is in, and table-driven tests for the edge cases are green locally and in CI. Since I don't have triage permissions, could a maintainer please add the |
Add support for 'scope' filtering (all, project, personal) to the mem_find_project MCP tool and SearchProjects store method. This allows agents to filter project discovery by scope, ensuring symmetry with the existing mem_search scope filtering (REQ-391).

Draft PR for #304. Dropped the preview field to keep the diff tiny. It only returns
Project, MatchCount, and TopRank (using FTS5 bm25). All MCP tool count tests updated.
