Summary

Add Live Feed between Projects and Dashboards on canonical PyAutoScientist. It shows five compact task rows with board links, recorded stage and time; explicitly linked issue/PR activity shares a row, history expands underneath, and new snapshots wait behind Show updates while someone is reading. Independent MyScientist/Embryo previews are unchanged.

Scripts Changed

• scripts/activity_feed.py: public-repository verification, bounded issue/comment/PR collection, normalized derived history, explicit grouping, coverage and static snapshot.
• scripts/live_feed.js: one-minute foreground refresh, stable reading controls, Show more, safe links and last-good fallback.
• scripts/organism_board.py: canonical-only placement and no-JavaScript publication snapshot.
• .github/workflows/organism_board.yml: five-minute best-effort collection, a two-minute request-time budget, and a derived cache branch; existing Pages publication serves activity.json.
• Renderer/collector/browser tests and reporting documentation.

Coverage and operational limits

Recorded public development activity only; no scientific run execution or interpretation. No raw comments, prompts or credentials are published. A source cursor advances only on complete collection; partial batches retain verified events and resume without repeated PR-detail requests. Request budgets rotate repositories and report gaps. The 5-minute schedule is an attempt interval, not a per-repository delivery guarantee. Initial backfill is seven days; retained snapshot history is bounded to 30 days, 1500 events/source, 200 tasks and 20 displayed events/task.

The workflow uses existing PAT_PYAUTOLABS when available (180 requests/cycle), otherwise github.token (60). Its dedicated scientist-activity-cache branch stores normalized derived data only; no history rewrite. Nothing has been deployed or scheduled from this feature branch.

Validation

• Full Python suite: 162 passed before the final board-mapping regression was added; final targeted collector/renderer/instance suite: 49 passed, including that regression.
• Existing overview JavaScript tests: 7 passed.
• Real Chromium: six width/theme cases, expanded history, deferred updates, preserved disclosures, Show more, unsafe-response fallback, no horizontal overflow or browser errors; no-JavaScript snapshot checked.
• Read-only live API pilot: PyAutoScientist, 37 grouped tasks, complete source coverage in 37 requests. This is not a claim of full-organism production coverage.
• Workflow YAML parsed, JS syntax and diff checks passed.
• Heart readiness STALE solely release validation incomplete: no rehearsal for current source; no red/yellow readiness reasons. Development shipping permitted.

Tier: judge — human /prm. After merge, publish via the Scientist Dashboard workflow and verify live feed and source coverage; no MyScientist rollout in this PR.

Closes #83.
