| `frameQuality.js` | Scores decoded video frames so a chained render can CHOOSE its continuation anchor instead of taking whatever an end-seek lands on. `scoreFrame({width,height,data},{recency})` combines three terms over a raw single-channel buffer: log-compressed `gradientVariance` (focus), distance of `meanLuma` from mid-grey (exposure penalty, which rejects a fade-to-black or a blown highlight), and a small linear recency bonus that keeps the anchor near the cut when candidates are comparably clean. Usability and ranking are deliberately separate: `usable` gates on raw gradient variance against `MIN_SIGNAL_VARIANCE` alone, so only a mathematically degenerate frame is rejected and a legitimately dark low-key tail still qualifies — the same contract `imageFrameStats.js` keeps. Gating on the composite score instead would reject every night scene on the exposure term. `TAIL_WINDOW_SECONDS` is capped at the reach of the single `-sseof -1.0` seek this replaces: focus is systematically highest at the OLDEST candidate, so a wider window would widen the backward jump at each chain seam rather than tightening it. `pickBestFrame(paths)` decodes each candidate through `sharp` and returns the winner (or `null` when nothing decodes or every candidate is degenerate, so the caller degrades rather than failing a render); its `index` is the position in the array AS PASSED, because the caller turns that into the anchor's time offset. `MAX_CANDIDATES` is derived from the window, never set independently — the ffmpeg-side `-frames:v` cap truncates from the NEWEST end, exactly the frames recency prefers. `TAIL_WINDOW_SECONDS` / `CANDIDATE_FPS` / `MAX_CANDIDATES` define the window the caller decodes from.

+ * exist and shipped; nothing proves they are the REQUESTED changes.
+ *
+ * This module owns the value half of that second review: the verdict
+ * vocabulary, the objective composition, and the parse/validate of the model's
+ * structured answer. The request itself lives in `services/codeReview.js`
+ * beside the other tool-free local-LLM prompts, and the completion gate in
