docs: runbook + AGENTS match reality (item 5 of the launch bar)

RUNBOOK-VERON: deploy uses fetch + merge --ff-only and api-only rebuilds
(the old text used git pull, contradicting its own warning); new sections
for host timers, CI (6 runners x1, windyadmin-scoped, 90m ceiling, queue
truth in the gitea DB, logs in R2), sign-in posture and break-glass;
standing checkout = OC5. AGENTS.md no longer says GENESIS / no code.

+## Timers (host systemd units — the sync timer is NOT in the repo)
+
+| Unit | Cadence | Does |
+|---|---|---|
+| `windygit-sync.timer` | every 5 min (`OnUnitActiveSec`) | GitHub → Windy Git for `REPOS` in `scripts/sync_from_github.sh`, then `scripts/pr_status_bridge.py` (mirror PRs + GitHub commit statuses). A manual `systemctl start` RESETS the 5-min clock. |

+| `windygit-ci-prune.timer` | every 6 h | `deploy/runner/prune.sh` — CI dind storage, 60 GB cap |
+| `windygit-tunnel.service` | always | the only ingress |
+
+## CI (Gitea Actions) — see `docs/CUTOVER.md` for onboarding a repo
+
+- **Six runners × capacity 1** (`deploy/runner/docker-compose.yml`), one shared
+  dind capped at 12 cores / 64 GB. Capacity >1 in one runner shares
+  `/root/.cache/act` between jobs and races (`lstat …: no such file`).
+- **Runners are scoped to the `windyadmin` user** (`action_runner.owner_id=1`),
+  so only first-party repos run. A repo owned by anyone else — a plane-created
+  agent or `u-system` repo — gets NO runner. Re-registrations inherit this
+  because `RUNNER_TOKEN` is user-level.
+- Job ceiling 90 min (`config.yaml` `runner.timeout`); a `config.yaml` change
+  needs each runner restarted **while idle** — `compose up -d` won't recreate it.
+- `/actions/tasks` lists only PICKED-UP jobs. Queue truth is `action_run_job`
+  in the `gitea` DB: `sudo docker exec -i windy-git-db-1 psql -U windygit -d gitea`
+  (status 1 ok · 2 fail · 3 cancelled · 4 skipped · 5 waiting · 6 running).
+- Job logs are in R2, not on disk. `GET /api/v1/repos/{o}/{r}/actions/jobs/{JOB_ID}/logs`
+  takes the `action_run_job` id, not the task id.
+
+## Sign-in posture
+
+- Windy SSO only: password + passkey forms OFF, `ACCOUNT_LINKING=login`,
+  **auto-registration OFF** — opening the forge to non-Grant users is a §7
+  Grant decision.
+- **Break-glass:** `sudo docker exec -u git windy-git-gitea-1 gitea admin user generate-access-token --username windyadmin --token-name <name> --scopes <scopes> --raw`
+  (delete it after: `delete from access_token where name='<name>'` in the gitea DB —
+  Gitea refuses token management over token auth).
+
 ## Troubleshooting
