-- [ ] Evaluate finer local ASR token/word timing and source-preserving phrase windows with Google text retrieval; preserve every competitor and reject invalid timestamps.
+- [x] Run frozen actual Google music metadata diagnostics: separate fields improved
+  known two-file music memories from 2/4 to 4/4; no-answer remained 5/5 failing.
+  This is hypothesis evidence, not independent production validation.
+  See [music evidence](MUSIC-METADATA.md).
+- [ ] Validate and integrate metadata embeddings on independent unseen music and
+  the full mixed pool with real field citations and stale-source guards.
+- [x] Implement exact artist/title constraints in shared storage, lexical/ANN
+  eligibility, CLI/MCP and desktop controls; metadata-only search skips inference.
+  Unit/lifecycle evidence is recorded separately from actual model validation.
+- [x] Actual Google CPU constraint integration passed with genuine tagged WAVs,
+  semantic/hybrid limit-one retrieval, empty absent identities, no-inference
+  metadata lookup and warmed lifecycle refresh; see [evidence](MEDIA-CONSTRAINTS.md).
+- [ ] Package and install an updated desktop release with these exact filters.
+- [ ] Evaluate finer local ASR token/word timing and source-preserving phrase windows
+  with Google text retrieval. Ordinary-token run completed but failed interval
+  validation; DTW run stopped on invalid native UTF-8 and remains incomplete.
+  Neither receives an accepted score. Future diagnostics retain bounded failing
+  raw bytes and atomic checkpoints; see tools/speech-eval/README.md.
 - [ ] Validate richer no-answer evidence on new independent positive/negative data; do not retune the failed universal cosine cutoff on old held-out results.
 - [ ] Integrate accepted improvements into shared engine/UI/headless clients with verified setup, lifecycle and CPU performance evidence. Diagnostics alone do not raise the media quality rating.
 - [x] Publish v0.1.0 Windows installer/checksum, verify public download bytes,
