grade-cliplisted

# grade-clip The keystone of the selection/repair/drip suite. The pipeline today is open-loop and produce-only — `qc-clip` checks only duration/size, `visual-cadence` is one diagnostic. Nothing ever inspects a *delivered pixel-level artifact* for upload-readiness. `grade-clip` is that gate: the on-disk translation of YouTube's un-exportable VVSA ("viewed vs swiped away") front-gate, scored 0-99 off the finished `.mp4` and its persisted sidecar plans. ``` grade-clip.sh <clip.mp4> # single / in-chain (after save-local) grade-clip.sh --backlog [output_dir=output] # sweep output/<src>/*.mp4 + _triage.json ``` ## Output — `clip_NN.grade.json` (locked SELECTION-SUITE-CONTRACT schema) ```json { "clip": "output/<src>/<title>.mp4", "grade": 0, "tier": "GOLD|FIXABLE|DROSS", "hard_caps": ["letterbox","face_withheld","credit_at_open","blocking_card","dead_tail"], "signals": { "frame1_is_face": true, "letterbox_bars": false, "credit_lit_at_open": false, "first_visual_change_sec": 1.2, "first_payoff_offset": 2.4, "longest_static_gap": 3.1, "opening_caption_words": 5, "max_residual_silence": 0.4, "terminal_loop_score": 0.37, "claude": {"hook_payoff":7,"open_loop":6,"cold_context":8} }, "fix_routes": ["broll_open_truncate","shot0_repunch","credit_rerender"], "source": "<source-slug>" } ``` ## Algorithm — deterministic retention-proxy floor (no model) - **`frame1_is_face`** — decode frame
