 - Gear fit (post-v0.6.0): Blender gear is measured against the avatar head/skirt silhouette and the checks run in both the Python tooling and the headless suite. Sunglasses, the shoulder bag and the firefighter helmet were fitted to the new faces; the Influencer portrait and gallery were recaptured with a before/after report.
 - Pre-build NPC review (2026-11-02): all eight library characters were staged at portrait, conversation and crowd distance on Hollywood and the Joke Shop, in day and night lighting, with the normal crowd hidden (`src/test/capture_npc_review.gd`). No P0 issues were found. Two P1 gear-fit issues were fixed with runtime attach offsets: the authorized-guest lanyard badge now clears the jacket and the firefighter helmet sits above the eyes. Backpack straps, caps, hands and the intentionally low-poly faces were accepted for the stylized target; close-range flashlight wash remains an optional-lighting follow-up. The 24-NPC budget stayed at 6.93 ms, the gallery passed 13 good / 0 bad and the screen-design judge stayed 13/13, and a clean portrait scored a 0.732 vision gap against the photoreal concept.
 
-Current gaps for v1.0.0: deeper authored content/dialogue, animation and audio production, localization/accessibility expansion, 24-NPC/platform profiling, external playtesting, and signed/notarized release packaging. The full gap analysis and milestone plan live in [`TODO.md`](../TODO.md); the current architecture and documentation ownership map are in [`docs/architecture.md`](architecture.md).
