Summary

• Reconcile all 12 area backlogs with source through PR Stamp welcome cards in, fade the scrim, and add a debug reset #311 (5f65b9f0), including PR feat(WhereUI): welcome users to their live region #309 that the previous report's stated source coverage missed. The inbox is empty.
• Archive three entries: shipped logged-in/out scope modeling, shipped local ingest/manual-sample fan-out, and the corrected WhereCore documentation cluster. Keep the summary, picker, and other partially implemented work open.
• File two welcome follow-ups: foreground lookup refresh and scrolling/modal snapshot coverage. Narrow the current-location marker request to what remains after the welcome feature.
• Correct overstated failure claims, moved citations, test/reference counts, and snapshot backlog formatting. Document actual reconciliation and snapshot-model-sharing limitations.
• Refresh MODULE_AUDIT.md with the commit boundary, module checks, and a derived inventory: 709 source files, 371 test/support files, 49 image-suite files, 495 references, and 25 test bundles.

Review focus

• The welcome foreground finding follows from the retained view's unchanged task key; its entry explicitly calls for a device reproduction before choosing the final trigger. No runtime fix is claimed here.
• Snapshot model sharing remains open even though its misleading documentation is corrected. Priorities are preserved.
• The September 9 benchmark-plan downgrade remains a saved deadline, not freshly verified billing state. The benchmark repository still exists and is not archived.

Verification

• ./swiftformat --lint — passed; 0/1,136 files require formatting, 125 skipped. The sandbox initially prevented writing the optional formatter cache; lint itself passed.
• ./shellcheck — passed.
• ./attribution --check — passed; 12 credits current.
• ./snapshot-shards check — passed; 49 suites assigned 13/15/18 plus 3 intake.
• ./sync-agents — passed after instruction changes; generated files remain ignored.
• git diff --check — passed. Both Swift diffs contain comments only.
• ./test, architecture execution, simulator/image suites, and retained Python/Ruby suites were skipped: this change contains Markdown and comments only, with no executable, reference-image, matrix, or rendered-copy changes. No fresh visual or live-motion validation is claimed. The automation's Linux/static-analysis limitations are preserved; this run used macOS host checks.
