- Any session operation that hits 404/410 (or finds no open tab) reconciles
tabs; if none survive it re-injects the account cookies (BR-2), opens a new
tab under the same userId/sessionKey, returns to the recorded URL (site home
otherwise), marks old tabs lost and retries the operation once. Failure
returns 503 browser_reconnect_failed with the reason, with a 10s backoff.
- Restart detection: umt plugin GET /umt/instance (fallback /health fields);
a changed instance id marks every open session needsReconnect.
- POST /browser/sessions/{id}/reconnect (idempotent); session view exposes
needsReconnect and reconnect {status, trigger, at, reason, humanNotice}.
- Controller and lease are kept; reconnecting during takeover asks the human
to double-check the reloaded page.
- Web: screenshot and desktop modes show "reconnecting", auto-reconnect once,
pause polling, offer a reconnect button with the reason on failure; desktop
mode rebuilds the Selkies connection after a reconnect.
- Mock camofox restart(), tests, smoke step and runbook section 10.

- Inject the site account Cookie (manual + auto-login session, session wins)
into the camofox profile before the first tab opens; password accounts
without a session run refresh-login first; API Key sites are skipped.
- Cookie expired after injection -> credential.status=expired; cookie
accounts go to waiting/login_required ("log in once, applies site-wide").
- Write back site-domain cookies from the browser on handover, session close,
every 10 min of activity, and from refresh-login when the stored cookie is
invalid (verified before saving). user_info.cookieOrigin records
source=browser; source shown as manual/login/browser in the origin view.
- New camofox plugin umt-cookies (GET/POST /umt/sessions/:userId/cookies
under the access key); profile dir 0700/files 0600 in the desktop image.
- Single entry: sources-identity/service/credentials.ts.
- Real check: HHClub cookie injected into a fresh profile -> home page
logged in (logout link present), 5 cookies read back.
Requires rebuilding umt-browser-desktop (docker compose build camofox &&
docker compose up -d camofox) to take effect.

With only a browser.solve_challenge grant, the vision child run was
denied browser.click_at, so the loop stopped after the first screenshot
(REAL-2 task 4). Steps inside a run spawned by solve_challenge are now
allowed; ancestors' allowlist and step budget still apply. Needs image
rebuild.

- browser.screenshot returns the page as an image content block (≤1280px wide, JPEG quality
configurable) for vision-capable upstreams; non-vision upstreams get a redacted text snapshot.
Login pages / password fields are marked sensitive and withheld unless a
browser.sensitive_screenshot grant exists and allowSensitive is passed.
- browser.click_at / type_at / scroll / wait act in screenshot pixels; the server converts via
viewport/DPR, requires automation control and an allowlisted host, and writes a thumbnail
evidence file (DATA_DIR/tmp/evidence) referenced from agent_run_event.
- browser.solve_challenge runs a bounded child agent_run (vision caps only, maxSteps ≤ 12,
budget), judges success from page facts, stops immediately on 2FA / SMS / device confirmation,
and otherwise moves the session to waiting with evidence and a takeover link.
- PiAgentRuntime passes modelImage outputs as pi-ai image content when model.input has image;
the ledger never stores image data; coordinate actions use per-invocation idempotency keys.
- Tests: image codec, runtime image content, E14 e2e (login solved, 2FA stop, step limit,
sensitive withheld). Real camofox 1.17.0 check on example.com recorded in the runbook.

- compose: camofox service on by default (internal only, volume umt-camofox,
healthcheck, CAMOFOX_REPLICAS=0 to skip); app depends on it with
service_started/required=false and auto-registers camofox-env from
BROWSER_PROVIDER_URL / BROWSER_ACCESS_KEY / BROWSER_ENABLED
- docker/camofox/Dockerfile: builds upstream tag v1.17.0 (389c996); fixes the
upstream Dockerfile (missing postinstall.js before npm ci, sh -c not
forwarding SIGTERM so logins were never persisted on restart)
- adapter fixes from the real container: coordinate click via evaluate +
selector, focus typing with mode=keyboard, password values redacted from
ARIA snapshots/extract, downloads field names, 410 after browser restart
treated as lost tab; navigate reopens a tab in the same session
- verified-capability table keyed by upstream version (1.17.0 all ten);
other versions stay unverified; probe reports auth failures
- settings: browser providers block (create/edit/delete/probe, capability
table); API POST/PATCH/DELETE /browser/providers, POST .../probe
- scripts/browser-verify: umtbr stack + mock NexusPHP run of REQ 4.7.4 items
- docs: runbook browser §1/§7 (real-instance record), deploy §2.1
