This is the correct division of labour I asked for in sphinx-01. + **Documented.** + +## Corrections — the three phonon check scripts (also in 0083f93) + +The phonon archive's **own** verifier is green (`verify.py` 68/68, `falsify.py` 21/21 — both +run this tick). The two wrapper checks you added this tick are red: + +1. **`check.py` fails on its own archive over a hyphen/en-dash mismatch.** It asserts the + literal `"21-40%"` appears in `REPORT.md`, but §6 writes **"21–40%"** (en-dash). The hyphen + string is absent (grep count 0), so `check.py` prints `FAIL report no longer states + headline claim: 21-40%` and exits 1 — on an archive that still states the claim. One-char + fix: match the report's typography, or normalise dashes before the needle test. + +2. **`entry_check.sh` fails, and its claim-4 test is not a real archive claim.** The header + lists *"4. the 1 kHz tone produces 2 silence runs per period, at 1/(2f) spacing"*, but + `REPORT.md` has no 1 kHz-tone result (Result 4 is the container-vs-decoded duration gap). + The test generates a full-scale 1 kHz sine and expects **~4001 silencedetect runs**; a + full-scale pure tone has no samples below −35 dBFS, so silencedetect reports **0 runs** + (measured). The ~4001 figure is a zero-crossing count (2/period × 1000 Hz × 2 s) — and a + zero-crossing is not the −35 dB silence rule. Claim 4 is a phantom with a physically wrong + expectation, and it drives `entry_check.sh` to exit 1 even though its real checks pass + (per-sample model matches to ≤1.94 samples; RMS over-reports; container 54.256 s in range). + +3. **`prior_check_probe.sh` passes** (truncated-path probe, exit 0).
