Documents the 2026-04-26 split of faceset_001 (707 curated faces) into
6 substantive era buckets + 68 thin fragments, including the readiness
probe evidence, the anchor-based assignment rationale (replaces
transitive union-find that caused year-drift), and the re-run / apply-
to-other-identity workflow.

- README: document work/build_folders.py (hand-sorted folder identities)
and the new age-split workflow for splitting a long-running identity
into era-specific facesets after clustering.
- Force-track work/age_split_001.py and work/check_faceset001_age.py;
these are the worked example + readiness probe for faceset_001 and
the template for splitting any other identity by EXIF era.

README.md now covers all six subcommands (embed, cluster, refine, dedup,
extend, enrich, export-swap), an end-to-end pipeline recipe, the delta
recipe for merging a new source into an existing result, the quality-
weight formula used by export-swap, and the GFPGAN blend recommendation
at swap time (0.85, overriding roop-unleashed's 0.65 default).

- enrich: re-detects each cached face with buffalo_l (detection +
landmark_2d_106 + landmark_3d_68, recognition module skipped for speed)
and persists landmarks + pose into the cache so per-face frontality and
landmark-symmetry quality signals become available.
- compute_quality: composite score combining det_score, face short-edge,
blur, frontality (from pose pitch/yaw), and 2D-landmark symmetry with
tunable weights. Default weighting 0.30/0.20/0.20/0.15/0.15.
- export-swap: builds facesets_swap_ready/ from an existing refine
manifest. Per identity: tighter outlier gate (default 0.45), visual-
near-dupe collapse (keep best representative per group), multi-face-
per-source-image collapse (keep best bbox), rank by composite score,
single-face-per-PNG crops at 512x512 with 0.5 bbox padding, ready-to-
drop .fsz bundles (top-N + full), per-faceset manifest.json, NAME.txt
placeholder for the operator. The multi-face-per-PNG collapse is the
critical fix: roop-unleashed's .fsz loader appends every detected face
in each PNG to the FaceSet, so any multi-face crop would contaminate
the averaged embedding.
- Optional --candidates rescues raw_full singletons: matches against the
final per-faceset centroids and routes to _candidates/to_<faceset>/
for manual review; orphaned singletons that still cluster among
themselves land in _candidates/new_<NNN>/.
- docs/analysis/: evaluation document captures the evidence, downstream
requirements (FaceSet averaging, inswapper_128), opportunity matrix
(R1-R14), and the recommended target state this export implements.

- embed: sha256-based dedup at listing (embed each unique hash once, carry
other paths as aliases via a top-level path_aliases dict); resumable from
any existing cache; atomic incremental flush every 50 files; explicit
skip-ext filtering; schema bumped with processed_paths + path_aliases.
- extend: new subcommand that merges new embeddings into an existing raw +
facesets output without renumbering. Nearest person-centroid match above
threshold, unmatched faces re-clustered into new person_NNN / _singletons.
Optional --refine-out also extends facesets by centroid + quality gate.
- dedup: new subcommand producing byte-identical + visual near-duplicate
groups as a JSON report.
- cluster/refine: fan every placement across canonical + aliases so each
on-disk location gets represented.
- safe_dst_name now always flattens the absolute path so filenames stay
stable across runs when src_root shifts (fixes duplicate-copy bug that
surfaced during the lzbkp_red extend).

Single-file CLI (embed / cluster / refine) using InsightFace buffalo_l
embeddings and agglomerative clustering, migrated in from the ad-hoc
/home/peter/face_sort/ directory so this repo is the canonical home for
faceset preparation feeding roop-unleashed and similar tools.
