docs(project-state): B6b shipped — final OCR gate numbers and live assertions

Also carries scripts/og-gen/sync_prompts_catalog.py, the check that keeps the
repo's art inputs (metaphors.json, captions/, prompts_catalog.json) in sync with
the authoring tool dir after any metaphor change.

 3. **Caption defect found and fixed (3 of 3 pilot frames).** With the subject described twice — `high_level_description` repeating the metaphor — the model drew a labelled diagram with a pseudo-title in the corner (`Oypert`, `Oyristes tool`, `CONTRACT`). One short noun phrase in the HLD + the subject only in `elements[].desc` cleared it.
 4. **The "no text anywhere" rule fails on the accepted samples too.** `sample_oom_169_00001_.png` OCRs as `Kenel L.aser` @0.874 plus six more hits. So the gate judges **legibility**, not hit count: a glyph box under ~14 px on the 1360×768 frame is invisible at banner (1600×900) and thumb (398 px) size.
 5. **The model renders the prompt's own label nouns as text.** Measured: `access-denied barrier` → "ACCCSS-DENIED", `attachment clip` → "Attachment Clip", `eight labelled ports` → a 389 px glyph, `id-stamped cards` → "ATACHMENT CLIP", `233 fresh rivets` → a row of numbers, `SSD slab` → a 66 px "SSD", `PLUGIN cartridge` → "PLUGIN". Rewriting the metaphor to describe shape/material/state only fixed every one of them on re-render.
-6. **Result after two correction rounds:** 45/72 frames fully clean, 18 with a single sub-threshold tick mark, and the 10 frames that exceeded the accepted reference all brought down to clean or reference level. Gate + tooling: `C:/AI/ideogram4/ocr_gate.py` (`--baseline` prints the accepted samples' numbers), `qc_frames.py` (per-frame stats + unlabelled contact sheets).
-7. **Delivery staged, not shipped.** Rendered 72 EN + 72 ZH cards, 144 banner files, 144 thumbs into `public/`; deleted the 144 v1 PNGs; migrated 288 frontmatter fields; fixed the two components. `npm run build` → **251 pages**, 216 distinct image references, **0 missing, 0 stale `.png`**; the ZH listing's thumbs resolve from the base slug (the old helper would have 404'd every one of them).
+6. **Result after three correction rounds (final gate, 2026-10-19 04:17):** **53 of 72** frames carry no ≥14 px OCR detection at all; **18** carry a single-character/geometry false positive only (`O`, `T`, `司`, `00%` — spot-checked by eye, they are edge and highlight misreads); **0** carry a legible word or phrase. Ten frames that had real pseudo-words were re-rolled (four of them twice), and every one came in at or below the accepted reference. The last two leaks were the model spelling an English noun phrase straight out of **the shared `style_description`** (`sleek developer tooling aesthetic` → "devalopertoolt"), so the style block is now free of generic noun phrases. Gate + tooling: `C:/AI/ideogram4/ocr_gate.py` (`--baseline` prints the accepted samples' numbers), `qc_frames.py` (per-frame stats + unlabelled contact sheets).
+7. **Delivery shipped 2026-10-19** (`327d516` → Gitea `main`, deploy green): 72 EN + 72 ZH cards, 144 banner files, 144 thumbs rendered into `public/`; the 144 v1 PNGs deleted; 288 frontmatter fields migrated; the two components fixed. `npm run build` → **251 pages**, 216 distinct image references, **0 missing, 0 stale `.png`**; live assertions afterwards: EN card 200 `image/jpeg`, ZH card 200 (did not exist before), banner WebP 200, thumbs 200 from both listings, v1 `.png` 404, and the ZH listing's thumbs resolve from the base slug (the old helper would have 404'd every one of them). The repo also carries the art inputs — `scripts/og-gen/metaphors.json`, `captions/<slug>.json` (72), a refreshed `prompts_catalog.json` with 72 distinct entries, via `scripts/og-gen/sync_prompts_catalog.py --check`.
 8. **Art weight: 13.4 MB → 15.4 MB (+2.0 MB), and it buys 72 ZH cards that did not exist before.** Per file: EN card 67 KB JPEG (v1 was 71 KB PNG), banner 40 KB JPEG + 30 KB WebP, thumb 7 KB WebP.
