Eric WagonerandClaude Fable 5.1 e1a740119c Credibility pass: the session seams sanded from the clips-and-camera batch
Two blind reviews of everything since the last pass (afa0e17), every
finding checked against the code, no behavior changed: all thirty
scene goldens match without a re-bless and the engine suite is
untouched.

Reel and renderer: the camera's look-down rule is stated once, beside
LOOK_DOWN, instead of twice in the effect; the empty aim branch that
stood where a cutaway used to be is gone (the guard it implied is now
explicit); the pit events and the punch are handled by their own
types, not through "in" casts; smoothstep is one export used by every
tween instead of eleven inline copies; the two floor rings share one
painter; project() takes a Billboard instead of a third hand-typed
copy of its fields; the strides-left figure and the web rim no longer
shadow the reel's steps and the pane's fx; the die card's verdict is
built from events, not by matching an emoji; the workshop asks for the
hover cue by name instead of passing an empty click handler.

Server and engine: one requestBase() for the origin, one slug pattern
in store.ts gating both the clip page and its files, one 404 for both;
LOOPBACK sits above its only caller; doCounteract names what a counter
is played against once; fearCells sits beside its own docblock rather
than between sightedCellsFor and its.

Deploy: chromiumExe, the private server, ffmpeg, and the reel rewind
live in deploy/lib/harness.mjs, shared by the gate, the recorder, and
the card cutter instead of pasted three times; the recorder drops its
duplicate frame counters and names its poster settle; the card uses the
gallery's exact gold; the one-time Sentry URL bootstrap leaves
deploy.sh; the backup comment states the rule rather than the incident.

// Make a clips directory unfurl well before clips-publish.sh ships it:
// - remux every mp4 with its index up front (faststart). Previewers in
// iMessage, Discord, Slack and Facebook read the head of the file to
// decide whether to show a player, and give up on a tail-indexed one.
// - cut a 1200x630 share card per clip — the poster's first-person
// viewport, full-bleed, with the title set over it — for og:image.
// Share sheets crop anything that isn't 1.91:1; X crops to 2:1.
// - stamp each clip's video width/height into clips.json so the page
// can emit og:video:width/height, without which Facebook, LinkedIn
// and Discord refuse to embed a player.
//
// npx tsx deploy/clips-prep.mjs <clips-dir>
//
// Needs ffmpeg + ffprobe and the Playwright chromium cache (see
// verify-scenes.mjs). Idempotent: run it again after re-recording.
