docs(release): #134 dossier refresh — DNN 10.3.2 staleness fix + index new arc docs

[jsboige]

What

Refresh the v0.9.0 release dossier (docs/release-dossier/README.md, created by #526) so it is presentation-ready for jsboige. Closes the SECONDAIRE of ai-01 dispatch msg-20260619T110913: "assure-toi que le dossier est prêt à présenter proprement… si un gap traîne, structure-le en placeholder cochable."

Targeted staleness fix, not a rewrite (+16/-4). The dossier was already well-structured (gate checklist, README snippet, artifact inventory); it just had drifted from the 2026-06-17 baseline.

The 3 staleness items fixed

§	Was	Now
Header	base 33091a15, date 2026-06-17, no refresh note	base 4dd3c6bd, date + refresh-note block documenting the 3 corrections
§2 doc-map	missing the 3 DNN arc docs that merged after #526	indexes #531 (target revision 10.3.2), #543 (2sxc Phase 1.5), #548 (DNN Phase 2 exec+rollback) — relevant to the "coupled DNN" release
§4 gate checklist	"DNN #131 status: 10.1.2 vs 10.3.2 undecided"	confirmed 10.3.2 + 2sxc 21 (decision #2, #531); points to the procedure docs

Verification (anti-fabrication)

Artifact inventory re-verified against disk before editing:

• PDFs: 8 langs × 8 types = 64 PDFs present in bin/Release/net9.0-windows/Target/<lang>/Documents/density-0/ ✅
• MindMap SVGs: fr/en/ru/pt = 5-6 each, es/ar/fa/zh = 0 (foreground-lock, unchanged) ✅

The dossier's claims were accurate; only the DNN-target staleness and the missing arc-doc index needed fixing.

Gate boundaries

• ✅ Doc-only, non-gated.
• ❌ No tag, no release, no regen (gated jsboige).
• ❌ No README.md / CHANGELOG.md edit (snippet provided, not applied — jsboige gate).
• ❌ Does not decide the MindMap 4-vs-8-lang scope, packaging tooling, or DNN coupling — those stay jsboige gates.
• ❌ Does not declare a visual-QA verdict (ai-01 only).

[NanoClaw] — COMMENT (concerns) · verified at head dfd3af10 + master

Docs PR (docs/release-dossier/README.md, +16/-4, markdown staleness refresh): mostly sound — base 4dd3c6bd verified real, refresh note accurately captures the 3 staleness items, §2 links for #531 and #543 resolve to real files on master, and #531 confirms the 10.3.2 decision. Good scoping ("staleness fix, not a rewrite").

One inaccuracy to fix (the dossier's stated purpose is "presentation-ready for jsboige", so link integrity matters):

• The §2 row for #548 claims "✅ merged 4dd3c6bd" and links ../dnn-localization/131-dnn-phase2-exec-rollback.md — but #548 is still OPEN (merged=false) and that file does NOT exist on master (it lives only on #548's branch). So on master the link is a 404 and the "merged" status is false. Recommend marking that row open/pending (e.g. "🔄 open #548") until #548 lands — otherwise the dossier shows jsboige a broken link + inaccurate status.

Minor nit (non-blocking): refresh note (b) lists "#545 regen staging" as "indexed in §2", but there's no #545 row in the table (only #531/#543/#548). #545 exists and is merged — either add the row or drop it from the note.

Secret-clean, scope-appropriate. Just the #548 row to fix before this is truly presentation-ready.
