-## Tooling Decision
+## Tooling Status
 
-- Intended skill for snapshots/screenshots: `agent-browser`.
-- Environment status: `agent-browser` CLI was not installed (`command not found`).
-- Fallback used: Playwright extension-runtime scripts:
-  - `scripts/extension-smoke-test.mjs`
-  - `scripts/long-duration-extension-validation.mjs`
+- `agent-browser` skill is installed and available in this environment.
+- `agent-browser` CLI is installed (`agent-browser 0.15.0`).
+- Runtime caveat on this machine:
+  - Default session (`default`) maps to a blocked Windows TCP port.
+  - Working approach: run `agent-browser` with an explicit non-default session (example: `--session car`).

 ## Additional Runtime Proof
 
-- Smoke command:
-  - `npm run test:smoke:extension`
-- Evidence output (JSON):
-  - dashboard heading found
-  - timeline container present
-  - runtime message responded with retention=30
-  - settings page loaded
+- Full automated quality gate:
+  - `npm run test:all` (unit + e2e): pass
+- Real extension smoke:
+  - `npm run test:smoke:extension`: pass
+  - Runtime response confirms `retentionDays=30`
 
 ## Conclusion
 
-- Automated quality gates are green (`test:unit`, `test:e2e`, `test:all`).
-- Real extension-runtime execution with screenshot evidence is complete.
-- For strict “real-user long-duration” sign-off, run headed long validation while actively using the machine:
-  - `$env:VALIDATION_HEADED='1'; $env:VALIDATION_DURATION_MINUTES='10'; npm run test:validate:long`
-  - then review artifacts in `artifacts/validation/<run-id>/`.
+- Automated test suites are green.
+- Extension runtime validation with long-duration multi-window activity is complete.
+- Screenshot/snapshot evidence is present under `artifacts/validation/*`.
+- `agent-browser` is usable for snapshot/screenshot capture with explicit session naming on this host.
