The chat surface now relies on the current-turn changes card for file rollback, so the older per-message hover rewind affordance was removed to avoid two competing rollback models.
Constraint: Current-turn undo still depends on the existing checkpoint rewind API.
Rejected: Keep both rewind entry points | duplicate rollback affordances make the product harder to explain and test.
Confidence: high
Scope-risk: moderate
Directive: Prefer adding rollback behavior through the current-turn change card instead of restoring per-message hover rewind.
Tested: bun test src/server/__tests__/sessions.test.ts
Tested: cd desktop && bun run test
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run build
Not-tested: Browser E2E scripts were updated but not executed in this commit.
The desktop updater now renders release notes as markdown, avoids fake 0%
progress when the server omits Content-Length, and remembers when the user
has dismissed a specific release prompt so reopening the app does not nag
again for the same version.
Constraint: Existing 0.1.4 clients can receive updater events without total size metadata and users still need a manual update path in About
Rejected: Keep repeating the prompt on every launch | creates avoidable noise after an explicit later decision
Rejected: Global dismiss flag for all future releases | would hide newer versions that should prompt again
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep prompt suppression keyed to availableVersion only; About page visibility and manual update actions must remain available
Tested: bun run test src/stores/updateStore.test.ts src/components/shared/UpdateChecker.test.tsx src/__tests__/generalSettings.test.tsx; bun run lint; manual local updater validation from 0.1.4 to 0.1.5 on /Applications and an extracted v0.1.4 release bundle
Not-tested: Signed and notarized macOS distribution behavior outside this local machine
