Context

Patchwarden needs a first-class way to validate web/UI behavior before a PR can be considered trustworthy. steel-dev/steel-browser is a strong candidate/reference for browser automation because it provides a browser sandbox/API aimed at AI agents and apps.

Goal

Add a Patchwarden module that consumes browser-smoke evidence from Steel Browser or a compatible browser automation provider.

Desired shape

Define patchwarden.web_smoke.v1 evidence with URL, scenario name, status, screenshots/artifact pointers, console/network summary, and sanitized failure reason.
Keep Patchwarden read-oriented: it evaluates the artifact, while the browser runner lives outside core.
Make the module usable for OpenClaw/Iskra-style web repos where a PR needs proof that the app still opens and key paths work.
Status page should show this as a missing/planned cheese-slice until wired.

Non-goals

Do not make Patchwarden a general browser automation framework.
Do not upload raw secrets, cookies, tokens, or full private logs.
Do not require Steel Browser globally if a repo provides equivalent Playwright/browser evidence.

Acceptance

ADR/design note for Steel Browser vs generic browser evidence boundary.
Minimal schema/example fixture for web smoke evidence.
Contract/status/docs updated.
Tests cover schema shape and redaction expectations.

🏛️ Architect (operator-directed reframe + keep)

The web-app half of Loop 1, for the operator's weak E2E/web coverage — it catches "looks fine but the app doesn't actually open / key paths break." Same boundaries as #150:

Steel Browser (Node + Chromium) is a strictly external producer; core stays a thin stdlib consumer of patchwarden.web_smoke.v1.
Offload execution, retain verdict: re-evaluate fail-closed + head-bound; fail closed when there's no current evidence for the exact head; sanitize hard (no cookies/tokens/raw logs — your non-goals already say this).
Keep it provider-agnostic: a Playwright/other browser run that emits the same web_smoke.v1 schema should satisfy it, so we're not locked to one dependency. That is the offloading philosophy done safely — the contract is ours, the runner is swappable.

Lower priority than test/sandbox evidence; sequence behind the merge frontier. — claude (architect)
