The boundary-detection paragraph understated the detector. Replace the stale
"~34% F1 vs ~27%" (a pre-C++-retrain figure with no backing artifact) with the
measured numbers at the shipped ±20s tolerance:
- leave-one-out macro boundary F1 = 44.1% (honest generalisation)
- grayscale baseline = 29.8%
- train-all (shipped model) = 72.9% (per-film 51-86%)
computed from experiments/results/scene_boundary/xgb_report.json and per-film
leave-one-out runs of train_xgb_cpp.py. Also correct the false claim that the
low-contrast grades "cannot generalise held out" — Scarface held out scores 32%,
Café Society 51%, both above grayscale (0% and 31%).
Split the evolution figure into two panels so the strict-±2s feature-development
curve is no longer mistaken for the shipped result: left = feature progress at
±2s, right = shipped detector at the ±20s tolerance the pipeline uses.
Auto-match each named July frame by film+actor+class and re-extract it from
the current learned-boundary flood replay, drawing GT-aware boxes: green TP,
red FP, orange unknown, plus the blue off-screen/missed (X-Ray cast, no face)
FN panel. Adds rematch_frames.py, the tool that does the matching.
Zooey Deschanel is dropped: the current pipeline no longer makes that
false identification, so the frame is removed and the July deep-dive notes
the fix rather than showing a stale error.
dump_error_frames.py drew every identified box green, so a false positive looked
like a true positive and a missed cast member was invisible. Make the annotation
ground-truth aware, matching what the per-second scorer classifies:
- GREEN true positive — a name X-Ray also credits to this scene
- RED false positive — a name X-Ray does NOT credit here (the real error)
- ORANGE unknown detection
- BLUE a text panel listing X-Ray cast present with no detected face (the
structural false-negatives — no box exists to draw)
Add two representative annotated frames to the scene-detector page: a clean
green-TP second, and the face-vs-scene-cast case (a red FP lead + six off-camera
cast in blue) that makes the recall ceiling visual. Frames are generated by the
script from replay.py --raw-out output; the two committed examples are hand-picked
doc assets (bulk experiments/dump_review is regenerable and gitignored).
- switch report frames to the scene best/worst montage renderer
(Onscreen/Offscreen panels + TPI/FPI/FN legend): perfect-second hero,
wedding couple, funeral 19-of-20, polygraph bridging, crew-scene FN
ceiling, Robert Patrick ground-truth gap, rapid-cut double label,
Herbie Hancock on an in-fiction screen
- deep dive restructured: extinction bridging framed as designed
behavior with a measurable cost (debug overlay draws the boxes; the
shipped output is presence windows), plus the face-vs-presence
ceiling and two X-Ray-is-wrong exhibits
- Material polish: light/dark palette toggle, landing-page grid cards,
figure/caption CSS, how-to-read admonition; site_url set so 404 links
resolve under the Pages subpath
- README: perfect-second and screen-call frames committed (gitignore
exceptions), readme_example.jpg retired
- build_site.sh: stage_frame helper downscales montage frames to 1920px
and pulls any missing montage-frames packages
- experiment_charts.py generates 4 figures from experiments/ artifacts:
held-out per-film F1, 16-combo ranking, DE search landscape, and the
Downton detector-vs-tracker ghost timeline (replaces the blank
title-card screenshot)
- new frames: 19-correct wedding shot (success case), Many Saints
ghost-vs-unknown frame (three error classes in one image)
- rename rep4-optimizer-results.md -> model-bakeoff.md; rep4 kept only
as the on-disk artifact prefix, explained once
- repo file references are now links via https://REPOLINK/<path>
placeholders; build_site.sh pins them to the HEAD commit's raw URLs
and fails the build if a linked path doesn't exist at HEAD
- drop references to removed scripts (scene_score.py, score_config.py)
and to session-memory names; mark artifact-registry paths with their
pull commands
- commit readme_example.jpg + pipeline_topology.svg so README renders
on the plain Gitea repo view
- deploy_pages.sh: push built site/ to the gitea-pages branch
