Summary

• Why the parity epic did not catch this: Epic Epic: Tasks kanban parity with GitHub Projects board (+ GodMode extras) #259 was GitHub Projects board parity (columns, card fields, sync, lifecycle), not full GitHub Issue page parity. Follow-ups Tasks: Project field parity leftovers (iteration, estimate, text, start date) #277/Tasks: GitHub lifecycle polish (Issue create + archive vs delete) #278 covered Project field leftovers and Issue create/archive. Tasks: stop GitHub sync poll remount flash; show Issue comments in card sheet #293/fix(tasks): sync poll no longer remounts board; Issue comments in sheet #294 added Issue comments and soft sync (explicitly out of scope: PR review threads and full timeline). Labels/assignees/Project moves live on the Issue timeline API and were never in those scopes.
• Fetch and show GitHub Issue timeline activity (labels, assignees, milestones, Project add/status changes, close/reopen, rename, etc.) on linked cards via existing App token (GET .../github/timeline).
• Regroup the card sheet into GitHub (Project fields, description, labels, activity + comments) vs GodMode (subagent, prompt, attachments, subtasks, local activity) without changing save/syncRevision soft-refresh behavior.
• Description Edit / Preview toggle using the existing Intelligence Markdown renderer.

Test plan

• Open a linked Issue card on /tasks; GitHub section shows timeline lines (e.g. labeled, Project status) and Issue comments
• Draft Project item still explains no Issue comments/timeline
• Description Edit/Preview toggles Markdown render; save still pushes body
• Soft sync poll does not remount/wipe the open sheet
• Local-only board keeps labels/description/activity under GodMode-style layout
• npx vitest run apps/bridge/src/services/__tests__/github-projects-timeline.test.ts

Follow-up

Open a Ready P1 for remaining Issue UI gaps (richer Project status from/to when REST omits them, PR review threads).
