 ## [Unreleased]
 
+## [1.6.7] - 2026-06-09
+
 ### Added
 
-- **Taint/PDG substrate (M0)** — foundational schema + seams for reliable taint analysis on a PDG-expandable substrate (#2080, Epic #2087). Adds the `BasicBlock` node label and `CFG` / `REACHING_DEF` / `TAINTED` / `SANITIZES` / `TAINT_PATH` relationship types to the graph schema (round-trip through the bulk-COPY path), a phase-registry seam (`registerPhase` / `enabledWhen`) generalising the graph-phase opt-in guard, and a per-language source/sink/sanitizer config registry seam. All additive and inert — no phase emits the new nodes/edges yet, and a default `analyze` run is byte-identical to before. De-risking spikes (LadybugDB rel-property indexing, post-dominator feasibility) recorded on the issue.
+- **Toolchain-free tree-sitter install** — the `c`, `dart`, `proto`, `kotlin`, and `swift` grammars now ship vendored native prebuilds (six platform/arch each — linux/darwin/win32 × x64/arm64, every `.node` load-and-parse verified with committed `SHA256SUMS` and SLSA build provenance), so a fresh install no longer requires a C/C++ toolchain; `kotlin` moved off its `optionalDependency` into the vendored path, `dart`/`proto` keep a source-build fallback when no prebuild matches, and a registry-parameterized CI workflow builds, load-validates, and vendors the binaries (#2113, #2125, #2110)
+- **`gitnexus uninstall`** — reverses `gitnexus setup` target-by-target, surgically removing GitNexus MCP server entries (Cursor, Claude Code, Antigravity, OpenCode, Codex), installed skill directories, and Claude Code / Antigravity hook entries with their bundled scripts; idempotent, JSONC-preserving, dry-run by default with `--force` to apply (#2062, #2060)
+- **MCP `list_repos` pagination** — bounded `limit`/`offset` paging so clients can reliably enumerate every indexed repository instead of having the unpaginated array truncated by LLM token limits; the result is now a `{ repositories, pagination }` object (page until `pagination.hasMore` is false), with deterministic `(lower-cased name, path)` ordering (#2120, #2119)
+- **C++ inheritance-lattice member lookup** — receiver members now resolve through the inheritance lattice with dominance hiding, ambiguous-base suppression, virtual-diamond deduplication, and overload ranking, and class-scope `using Base::member` declarations are no longer mistaken for namespace imports (#2077, #1891)
+- **Taint/PDG substrate (M0)** — foundational graph schema and pipeline seams for reliable taint analysis on a PDG-expandable substrate: the `BasicBlock` node label and `CFG` / `REACHING_DEF` / `TAINTED` / `SANITIZES` / `TAINT_PATH` relationship types (round-tripped through the bulk-COPY path), a phase-registry seam (`registerPhase` / `enabledWhen`) generalising the graph-phase opt-in guard, and a per-language source/sink/sanitizer config registry. All additive and inert — no phase emits the new nodes/edges yet and a default `analyze` run is byte-identical to before (#2092, #2080)
+
+### Fixed
+
+- **Optional grammars lazy-loaded so `analyze` never crashes when one is missing** — the swift/dart/kotlin `query.ts` modules no longer statically import their tree-sitter binding at module load, so a missing optional grammar can no longer abort `gitnexus analyze` (or the MCP server, `doctor`, and `.githooks` auto-reindex) with `ERR_MODULE_NOT_FOUND` regardless of the repo's actual languages; grammars now resolve lazily at first use inside the worker, `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` is honored at runtime, the scope-resolution phase excludes unavailable-language files, and skip diagnostics/precheck globs were corrected (#2101, #2091, #2093)
+- **`tree-sitter-kotlin` optional-grammar install** — install now fails soft when no C/C++ toolchain is present, emitting one clear warning and always exiting 0 (mirroring the Swift/Dart/Proto probes) instead of breaking `gitnexus` install; optional-grammar/toolchain docs corrected to include Kotlin (#2110, #2107)
+- **CLI image FTS keyword search** — the full-text-search extension is now baked into the CLI Docker image so a containerized `serve` does offline keyword search instead of silently degrading to vector-only (#2108)
+
+### Changed
+
+- **Tree-sitter prebuild CI matrix greened and made re-run-safe** — dropped the broken `-t 22` flag from the `prebuildify` invocation that crashed every matrix job (`v.indexOf is not a function`; N-API prebuilds are Node-version-agnostic, so no target is needed) (#2121), cleared npm-bundled `prebuilds/` before prebuildify so the host tuple is detected (not a stray `win32-x64`) and source-built the `tree-sitter` runtime peer on `linux-arm64` where upstream ships no prebuild (#2122), and switched the vendor-prebuilds push to `git push --force` so re-running a workflow no longer fails with a stale-lease rejection (#2123)
+
+### Performance
+
+- **MCP `query` enrichment batched** — the `query` tool now batches its per-symbol enrichment lookups (3N sequential pool round-trips collapsed to 2–3 `WHERE n.id IN $nodeIds` queries), cutting N+1 round-trips with byte-identical output (#2108)
+
+### Chore / Dependencies
+
+- **`@ladybugdb/core` bumped 0.17.0 → 0.17.1 in /gitnexus** (#2098)
+- **Claude plugin manifests synced to the release version** — bumped `plugin.json` and the `gitnexus` `marketplace.json` entry to match the published npm version (stale `1.3.x` manifests had blocked marketplace updates), added a Vitest guard asserting all three manifests advertise one version, and documented the sync step in `CONTRIBUTING.md` (#2090)
