Closing a deliberate half-step from spec 241 — every byte that lands in the STAC catalog now crosses the same writer boundary.

Promoted spec 241's tactical scene-thumbnail regex to a first-class LinkML shape with documented pairing and ULID rules — and a Python audit for the constraints JSON Schema can't express.

Same Backlog Navigator app, same parser and push pipeline, now usable on a phone — installable as a PWA with an offline app shell.

Web-shell captures, edits, and new tracks now persist across reloads via IndexedDB, behind a shared StacWriter interface used by both hosts.

Lifted the bundled catalog to STAC 1.1.0, swapped bespoke debrief lineage fields for the standard processing and file extensions, and proved it renders in radiantearth/stac-browser.

Turned the 230-row pipe-delimited BACKLOG.md into a sortable, filterable, group-by-epic web app with staged edits and a deliberate Push Changes PR.

Un-muted the LogPanel E2E suite after the openvscode-server lifecycle bug landed, with one passing scenario, four narrow-muted, and a restored skip-guard.

Five quality items deferred from the wiring patch — interactive stories, code-server E2E, axe audit, perf budget, full scenario set — closed in one PR.

Mermaid fences in Future Debrief blog posts now render as real diagrams on the published site, not as raw text.
