cleanup: exempt pil-* generators from bleed_guard + delete dead /fix route
a5384f5624cff5e94e07e8d5280ba697607d5876 · 2026-05-26 08:37:28 -0700 · Steve Abrams
Two issues surfaced during the mid-heal verification:
1. bleed_guard.js was re-blocking pil-mid-heal rows
The 24px Gaussian band-blur at H/2 and V/2 (intentional, surgical, the
reason the mid-heal works at all) trips Gemini's "halftone_layer" /
"atmospheric_haze" detectors. Result: 38 of the 7,329 freshly-healed
rows got is_published=FALSE within minutes of insertion. Adding
`AND (generator IS NULL OR generator NOT LIKE 'pil-%')` to the
candidate query at both the --last-n and tick branches. This exempts
pil-mid-heal, pil-fix, pil-fix-design, pil-opacity-snap — all
already-vetted by a deterministic pipeline, none should be re-eval'd
by the AI ghost detector. Re-published the 38 was NOT part of this
commit (leaving for a separate decision); going forward they'll stop
getting flagged.
2. Duplicate /api/design/:id/fix route was dead code
Two handlers were registered for the same path — first at line ~7088
(delegates to scripts/fix-seam.py, the edge-seam-only repair, this is
the one actually used) and a shadow at ~7796 (PIL median-cut canonical
fix added 2026-05-25). Express first-match means the shadow could
never run from any frontend or CLI. Deleted to remove ambiguity.
If a future caller needs PIL median-cut they can use the existing
/api/design/:id/opacity-snap endpoint (defined below the deleted one).
Verified post-commit:
- Syntax OK on both files
- Exactly 1 surviving /api/design/:id/fix route
- pm2 restart clean, /designs returns 200
- Surviving /fix endpoint behavior unchanged (returns already_seamless:1
for the same id 40689 it returned earlier this session)
