+# Phase 10a — Stabilization Gate
+
+## Scope
+
+This checkpoint updates the 2026/04/25 handover and static Phase 10a audit for the current local `main`, which is two commits ahead of `origin/main`.
+
+Current local-only commits inspected:
+
+- `c95a5da` — `docs(roadmap): bookmark SIE + adjacent embeddings/rerank/extract servers for PKM phase`
+- `6bc8acc` — `feat(transcription): Phase A — engine protocol + registry + orchestrator (clean-room)`
+
+## Findings
+
+### PKM roadmap bookmark
+
+Low release risk. The SIE / embeddings / rerank / extraction note is documentation-only and explicitly marked deferred. It should not affect v0.1 runtime or QA scope.
+
+### Phase A transcription orchestrator
+
+Medium architectural scope, low immediate runtime risk.
+
+The commit adds:
+
+- `crates/cloud-providers/src/provider.rs`
+- `crates/transcription/src/registry.rs`
+- `crates/transcription/src/orchestrator.rs`
+- wiring exports/dependencies plus `KNOWN-ISSUES.md` KI-06
+
+The implementation is deliberately dormant for current app paths. Existing `transcribe_file`, live transcription, and meeting flows still call the existing local engine path directly. KI-06 documents the required follow-up: build the registry at app boot, inject `Arc<Orchestrator>` into `AppState`, and migrate command call sites through the orchestrator with mock-provider coverage.
+
+Decision for v0.1 release flow: keep the Phase A commit only if the dormant boundary remains green; do not expand scope into Phase A.1 before Phase 10a unless a direct release blocker requires it.
+
+## Verification run
+
+Command run from repo root:
+
+```bash
+cargo fmt --check && \
+  cargo clippy --workspace --all-targets -- -D warnings && \
+  cargo test --workspace && \
+  npm run check && \
+  npm run build
+```
+
+Final result: PASS.
+
+Notes:
+
+- Initial run failed `cargo fmt --check`; `cargo fmt` was applied.
+- Current Rust/Clippy toolchain also surfaced a few warning-as-error issues unrelated to the new orchestrator surface:
+  - `manual_range_contains` in `crates/core/src/tuning.rs`
+  - `assertions_on_constants` in `crates/core/src/tuning.rs`
+  - `println_empty_string` in transcription benchmark tests
+  - `trim_split_whitespace` in transcription benchmark helper
+- Those were fixed minimally to restore `-D warnings` cleanliness.
+
+## Files changed by stabilization
+
+Rust formatting touched multiple existing files. Semantic clippy fixes were limited to:
+
+- `crates/core/src/tuning.rs`
+- `crates/transcription/tests/jfk_bench.rs`
+- `crates/transcription/tests/thread_sweep.rs`
+
+This audit file records why those changes exist.
+
+## Recommendation
+
+Resume the original Phase 10a plan now, with this added gate satisfied:
+
+1. Current HEAD is green.
+2. Post-handover commits are inspected.
+3. Phase A orchestrator work is classified as dormant / post-v0.1 follow-up, not a reason to expand release scope.
+
+Next work remains the manual/runtime Phase 10a checklist:
+
+- Dogfood walkthrough from `HANDOVER.md`
+- Runtime keyboard / focus / contrast / reduced-motion checks
+- RB-08 macOS power-assertion verification by Rachmann
+- Clean-install test once release artefacts are available
+- Manual GitHub Actions build workflow before tagging v0.1.0
