Prefer the repo fingerprint matcher in the real-directory song-centric pipeline
Constraint: Improve the current directory-to-feature path using components already present in the repo, without depending on unavailable heavyweight semantic runtimes. Rejected: Keep exact-lane validation on a purely ad-hoc local hash path | It underuses the repo's existing fingerprint extraction capability and weakens evidence for the real pipeline. Confidence: high Scope-risk: narrow Directive: In host-level song-centric pipeline validation, prefer ChromaprintMatcher-backed fingerprints first and use local_wavehash only as fallback. Tested: /usr/local/miniconda3/bin/python acr-engine/scripts/enrich_songcentric_manifest_with_local_features.py on the real wav smoke manifest; imported the enriched manifest into postgres://d2:d2pass@127.0.0.1:5432/d2 schema acr_songcentric_test twice and verified counts stayed media_entity=9, audio_object=22, feature_fact=24, set_membership=9 on rerun; matcher_fingerprint_count=5 and fallback_fingerprint_count=0; git diff --check; /usr/local/miniconda3/bin/python scripts/check_markdown_links.py --root docs returned OK for 11 active markdown files Not-tested: true external chromaprint library integration and semantic-model-backed enrichment on this host

| 304 | ### 4.8 目录链中的 exact lane 提升 | ||
| 305 | |||
| 306 | 当前 `enrich_songcentric_manifest_with_local_features.py` 已优先复用仓库内 `ChromaprintMatcher` 生成 fingerprint;只有失败时才回退到 `local_wavehash`。 | ||
| 307 | |||
| 308 | 本轮 fresh evidence: | ||
| 309 | - `wav_windows_seen = 5` | ||
| 310 | - `matcher_fingerprint_count = 5` | ||
| 311 | - `fallback_fingerprint_count = 0` | ||
| 312 | |||
| 313 | 这说明当前目录链里的 exact lane 已经不只是临时 hash,而是优先接上了仓库现有 fingerprint 提取能力。 | ||
