feat(board): session attention, Discord rows, task attribution and relaunch activity (rows 18, 22, #1511, #1512)

One cumulative control-board, webui and seat state. The four rows edit the
same files (scan.mjs, page.html, README.md, app.js), so they land together,
each on its own receipt:

- Row 18, Discord connector rows on the board (#1509): R3 approved by
  Darkwing and Dewey, Gitea comment 26257, manifest 254403b8. Jason
  accepted the visual test.
- Row 22, board attention status (#1503): Filbert approved R1, comment
  26248, manifest e40b58ec; restart receipt 26249.
- #1511, task attribution (row 6 code phase): R2 approved by Filbert and
  Dewey, manifest d4c96395. docs/TOOLS.md carries the approved --by usage
  line (tools-usage.patch 86bcba3c).
- #1512, relaunch activity (row 6 pilot): R1 approved by Darkwing and
  Dewey, candidate manifest 47769fad. All seven source files match it.

Row 16, internal development bootstrap (#1510): the seven files outside
shared records match Filbert's R1 pins, receipt 26204 (agents/researcher/*,
scripts/test-darkwing-launch.mjs, the bootstrap plan).

packages/webui/src/public/app.js is committed at its #1512 R1 pin ce7d79a4.
The working copy holds Dewey's unreviewed return-flow candidate on top of
that, and it stays uncommitted.

Also: the four row briefs and Darkwing's evidence records under
agents/darkwing/work, including the 2026-09-26 tree manifest and the #1512
re-run against 21e3e908. Serial acceptance command: 397/397, three runs.
The failures that only show when tests run concurrently are in #1509 engine
tests, and they reproduce on clean HEAD.

Suites on the exact staged tree: config 24, task 90, foundation 43,
conductor 17, release 14, auth 15, discord 63; package union 397/397
(serial); test-darkwing-launch 5/5.

Shared records (BUILD-LOG, QUEUE, CURRENT, DEFERRED, SESSIONS, AGENTS.md,
agents/README.md) follow in Sage's records commit.

+# Proposed #1511 local test envelope
+
+Original proposal retained below. Jason authorized the backend update, completed
+2026-09-15. Rocko's stale registration blocked that target before mutation.
+Jason then explicitly authorized Filbert instead and confirmed Claude console
+integration remains separate. The Filbert metadata update and live API checks
+passed; operator visual acceptance is pending. Receipt: live-test.jsonl.
+No Rocko registration or process was changed.
+
+- Reverify the approved R2 pins and current backend PID/start/command/config.
+  Record the five native agent identities and connector service identity.
+- Restart only the control-board backend on loopback 7331, using its existing
+  command/config. Do not restart agents, WebUI or the Discord connector.
+- Verify health and that the updated reader accepts existing records. Check
+  actual asset loading before claiming either presentation loaded R2.
+- For the visual test only, update the repository-native Rocko registration's
+  task to '#1511 task attribution user test', with explicit setter darkwing.
+  Use the reviewed seat task command and explicit repo layout. First verify the
+  registration matches the intended native session; a mismatch blocks the write.
+- Preserve the original registration privately outside the repository. Never
+  print its contents. Assert only task, taskSetBy and updatedAt change, with all
+  identity fields and startedAt preserved. No other registration may change.
+- Verify API selection and ask Jason to inspect the 'set by darkwing' tag and
+  caller-claim wording. Legacy registered attribution remains unknown; inferred
+  and connector tasks remain not applicable. Agent/connector identities unchanged.
+
+Rollback: before any attribution write, an incompatible old reader can be restored
+only from the retained prior artifact. After the one authorized write, restoring
+an old reader requires restoring that record's original task metadata first, with
+an exact unchanged-current-record check. If anything else changed, stop rather
+than overwrite it. Keep the compatible reader while resolving the conflict.
+No broad metadata migration or automatic rollback over concurrent edits.
+
+This envelope does not authorize publication or the later Filbert behavior task.
