Add model-bakeoff.md for the opencv5 build: the ten-knob DE tuning and where
each shipped config default comes from, the replay architecture, and the
flood-fill-on-learned-boundaries step change (62.6% -> 74.9% presence F1, LOO).
Rewrite index.md to lead with the learned scene-boundary result and point at
the current pages, with the July four-model bake-off moved to an Archive
section. Both pages build with no broken links.
The July report (4-model ArcFace/LVFace bake-off, pre-opencv5 framework,
3-film training + held-out validation) is superseded by the opencv5 build:
single-model LVFace-B, a 6-knob DE sweep over all 9 films, flood-fill
presence, and the registry/decode fixes. Rather than overwrite it, archive
it date-suffixed and start the current report fresh.
- Rename the six July result pages to *-2026-07.md, rewrite their
intra-archive cross-links, and add an "Archived (July 2026)" banner to each.
- mkdocs nav: current report at top, the July set under an Archive section.
- New docs/methodology.md for the opencv5 run: corrects the withdrawn
anneal_sec/extinction_sec presence bridging (windows are now
[first_seen, last_seen], AR-012/013), documents the two presence modes
(track_extent / flood), and records that every eval scores all 9 films.
The current experiment log (model-bakeoff.md) and Home rewrite land once
the DE sweep converges and the final optimum is known.
Replaces narrative claims with verified numbers across all report pages:
- Cross-model held-out validation (LVFace/mbf/r18, all 5 held-out
films): LVFace wins every film outright, not just "consistent with"
the training-set pick. r50 dropped from the detailed comparison
(gallery has ~30% fewer reference images per actor than the other
three models on identical source photos).
- Per-film training breakdown: LVFace does not win every training
film (mbf beats it on Lord of War); the 75.3% macro figure hides a
10.7pp spread.
- Gallery coverage computed per film (20.3%-78.6%) instead of one
flat 67%-missing average.
- Found and fixed a real scoring bug in optimize.py: a candidate
whose hardest film's replay timed out was averaged over survivors
instead of penalized, silently rewarding partial coverage. Affected
3 of 16 training combos; corrected throughout, and optimize.py now
scores an incomplete evaluation f1=0.0 instead of averaging over
whichever films happened to finish.
- Every FPI frame in the deep dive now comes from the proper montage
renderer (Onscreen/Offscreen panel, ghosts never drawn as boxes),
never the bare-box debug overlay used earlier.
- Every distinct out-of-cast name across all 9 films gets its own
frame at its first appearance (9 names, 4 films), not a
single-example spot check: 2 ground-truth gaps, 1 photograph
misread as a person, 6 genuine lookalike confusions.
- New methodology.md: the scene-level-vs-per-second scoring mismatch
that the rest of the report assumes, written out once.
- Cut the deadlock/gdb debugging narrative from the experiment log;
kept the one fact that matters (KPN's node/network split lets the
expensive GPU stage run once and the cheap stage replay against
cached embeddings).
- Plain declarative style throughout, no em dashes, no blog voice.
- 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
