Wire the caption merge, and write the target architecture down

merge_faceless_captions had been written and never called; both crop
endpoints called the non-destructive context_fragment_links instead, with no
decision recording that choice. Wiring it changes panel count and every panel
index, so the chapter needs a re-crop with the panels prefix cleared first --
crop_webtoon skips an upload when the key already exists, which is right for a
resume and silently wrong after a slicing change. Noted at the line.

It does not cover the head-in-one-shot body-in-the-next split that prompted
the question. _merge_plan only folds a fragment that has text and no face.

ARCHITECTURE.md is the target shape from the user's design, with what exists
against each section today. Nothing in it is built.

+## 2026-08-13 — the dialogue stage names nobody, and why
+
+Ran `dialogue` 116/116 in 5m57s on the fourth cycle's registry, to see whether the fixed identity lets the
+existing `name_claims` path name the female lead. It does not, and the six claims it produced name three
+separate defects.

+
+All three are fixed in `db.add_name_claim` and recorded in `decisions/identity-naming.md`: alias grouping,
+a confident caption as strong evidence, and one name per character. `test_name_binding.py` replays these
+six claims, 121 tests pass, and each new assert was confirmed to fail with its fix disabled.
+
+Also wired `merge_faceless_captions` into both crop endpoints. It had been written and never called; both
+endpoints called the non-destructive `context_fragment_links` instead, and no decision recorded that
+choice. It does not cover the head-in-one-shot, body-in-the-next split that prompted the question, because
+a body fragment has no text and `_merge_plan` only folds a fragment that has text and no face.

+Found while wiring it: `crop_webtoon` skips an upload when the key exists, which is right for a resume and

+
+Wrote `ARCHITECTURE.md` from the user's design: region graph, occurrence/identity/name, speaker as a scored
+graph edge with a typed union, narrative plane for art-in-art, and a persistent story state machine. Every
+section carries what exists against it today. Nothing in it is built.

+Nothing ran on a GPU after the dialogue stage.
