SummaryThis PR adds a production MCP (Model Context Protocol) server, a CLI for managing it, and an npm launcher. The functional Swift code is generally well-structured and respects the Wax architecture. However, several issues need attention before merging. Critical Issues1.
2. Architecture Invariant #1 violation: In try await MainActor.run {
try LicenseValidator.validate(key: resolvedLicense)
}
3. Tie-break test weakened without documenting why
// Before:
#expect(ctx.items.map(\.videoID.id) == ["zeta", "alpha"])
// After:
#expect(Set(ctx.items.map(\.videoID.id)) == Set([zetaID.id, alphaID.id]))
#expect(ctx.items.map(\.videoID.id) == ctxRepeat.items.map(\.videoID.id))Architecture Invariant #6 requires deterministic tie-breaks. Weakening this assertion to only cross-run consistency (without asserting a specific order) means that if the tie-break behavior changes, tests won't catch it. There should be a comment explaining why the specific order is no longer asserted, or the specific order assertion should be restored. Fix this → High Issues4.

case "wax_photo_ingest":
_ = photo
return redirectToSoju() // isError: false — misleading5. License validation is client-side format-only — provides no real protection
6. Stale The PR adds 7. Similar to the above — Medium Issues8. In .filter { $0.confidence > 0.3 }This threshold is magic. Low-confidence Vision labels combined with text embeddings could degrade recall quality. The threshold should be a configurable constant or at minimum named ( 9.

The doctor smoke test writes a raw tools/list request directly to the server without the required MCP session handshake (initialize followed by initialized), so a protocol-compliant server can reject the request even when the installation is healthy. In that case mcp doctor reports a false failure for working setups, which makes the diagnostic command unreliable in normal MCP environments.

There was a problem hiding this comment.
optionalInt returns Int(string) directly, so non-numeric strings become nil and callers silently use defaults (limit/topK) rather than surfacing an argument error. For example, passing "topK":"abc" is treated as if topK was omitted, which hides client/tooling bugs and produces unexpected query behavior instead of a validation failure.

SummaryThis is a final review pass of the current branch state after six commits. All critical and high issues from previous review rounds have been fixed correctly. The code is in good shape. A few residual observations follow — none are blockers, but three are worth addressing before merge. Worth Fixing Before Merge1. Tie-break test still doesn't pin a specific order — comment is inconsistent with the assertion
// The specific order (alpha vs zeta first) is intentionally not pinned here because it
// depends on the underlying store's frame ID assignment order, which is test-environment
// dependent.
#expect(ctx.items.map(\.videoID.id) == ctxRepeat.items.map(\.videoID.id))The comment says frame ID assignment order is test-environment dependent, but the test constructs frames in a deterministic sequence: Recommendation: Pin the specific expected order (run the test once, observe the result, and assert it directly), OR add a stronger rationale. The current comment makes it sound like the order is non-deterministic when it isn't. 2.

…output, schema TODO - Pin specific tie-break order in VideoRAG recall test (Invariant #6): zetaRoot is inserted before alphaRoot so it gets a lower frame ID; the sort at VideoRAGOrchestrator.swift:363 uses `a.rootId < b.rootId` ascending, so zeta always precedes alpha. Assert the specific order instead of only cross-run consistency. - Add `-D MCPServer` swift define to WaxMCPServer target in Package.swift so `#if MCPServer` conditional compilation guards are actually active when the MCPServer trait is enabled. Without this define, all MCP-specific code was dead code even when the MCP dependency was linked. - Clarify `mcp doctor` output: when dependency checks fail the smoke check is skipped; now appends an explicit "Server smoke check skipped" message so users understand the server was not exercised. - Add TODO comment to empty photo tool schemas in ToolSchemas.swift marking them as placeholders pending Soju integration.

… static ref clarity
- Package.swift: Add .define("MCPServer", .when(traits: ["MCPServer"])) to
WaxMCPServerTests swiftSettings so #if MCPServer guards in test source resolve
to true when building with --traits MCPServer. Without this, all 11 substantive
MCP server tests always fell back to the no-op mcpServerTestsRequireTrait stub.
- ToolSchemas.swift: Replace emptyObjectSchema() with stubObjectSchema() for
wax_photo_ingest and wax_photo_recall. The new helper uses additionalProperties:true
so MCP clients that pass arguments (e.g. path, query) reach the tool handler
and receive the informative "Requires Soju" isError:true response, rather than
being rejected by schema validation before the tool runs.
- MultimodalAdapter.swift: Use MultimodalAdapter.minimumLabelConfidence (explicit
type qualification) inside Task.detached closure to make clear it's a static
property and no instance capture is involved.

Implements a new WaxRepo executable target that indexes git commit history into a Wax store and provides interactive terminal search. Architecture: - Git layer: GitLogParser (state machine) + GitCommit model - Store layer: RepoStore wrapping MemoryOrchestrator with structured header encoding for metadata recovery from search previews - CLI: index/search/stats subcommands via ArgumentParser - TUI: SwiftTUI split-pane views (header, commit list, diff preview) - Async bridge: SearchViewModel (ObservableObject) bridging Wax async APIs to SwiftTUI's synchronous render loop Key fixes applied during integration: - Pipe buffer deadlock: read stdout before waitUntilExit to prevent 64KB buffer deadlock on large git log output - MiniLM graceful fallback: CoreML batch prediction fails in CLI executable context; falls back to text-only search with warning - Incremental indexing via last-indexed-hash checkpoint file Build: swift build --traits WaxRepo Usage: swift run --traits WaxRepo WaxRepo index && search "query" Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Not addressed (cannot fix):
|
- CONTRIBUTING.md: Replace hardcoded local dev path with "repository root"
- Package.swift: Add .define("WaxRepo", .when(traits:["WaxRepo"])) to WaxRepo
target so #if WaxRepo guards are active when building with --traits WaxRepo
- Views (CommitListView, DiffPreviewView, HeaderView): Add #if WaxRepo && os(macOS)
guards + #endif so files only compile when trait is active
- Views (SearchView, SearchApp): Upgrade existing #if os(macOS) to
#if WaxRepo && os(macOS)
- SearchViewModel: Upgrade #if os(macOS) to #if WaxRepo && os(macOS); replace
@unchecked Sendable with @mainactor for proper actor isolation; remove now-
redundant await MainActor.run {} call sites
- GitLogParser.runGit: Move readDataToEndOfFile + waitUntilExit onto
DispatchQueue.global(qos:.utility) to avoid blocking the Swift cooperative
thread pool
- IndexCommand: Remove redundant Array.prefix(maxCommits) — GitLogParser already
passes -n to git when maxCount > 0
- RepoStore.parseResult: Return nil (not empty-field CommitSearchResult) when
the preview lacks a structured header or the header is malformed, so compactMap
filters them rather than displaying blank rows in the TUI
- production_readiness_gates.sh: Replace rg with grep -E (rg is not installed
by default on macOS GitHub Actions runners)
