Exact-head self-review on e3b2b412d8ad880c87354fb3ffd5f5b4ff6cde0d: the initial proposed acceptance was too broad because WebDriver BiDi screenArea controls width/height while OriginWeave ScreenMetrics also includes page-observable color depth. That false-GREEN path was removed before production acceptance. The final source uses a dedicated WebDriverBidiScreenArea projected from validated ScreenMetrics, carries no color-depth field, plans context-scoped Set/Reset screen-area intents, and keeps PresentationSurface::Screen absent so complete admission remains MissingSurface(Screen). I also rejected the intermediate shape that carried full ScreenMetrics in the protocol intent because it retained an unapplied field. No live transport, command-ACK success, page-observed state, or browser cleanup claim is made. Repository acceptance remains pending exact-head CI and independent review; this is COMMENT only, not approval.

Exact-head finding on e3b2b412d8ad880c87354fb3ffd5f5b4ff6cde0d: the new SetScreenArea intent is derived from ScreenMetrics(width,height,color_depth) and is automatically included in plan_standard_presentation_commands, but W3C emulation.setScreenSettingsOverride does not mutate only total screen width/height. The command explicitly emulates both the web-exposed screen area and the web-exposed available screen area for the target context, using the same screenArea rectangle (WebDriver BiDi §7.4.2.5, https://www.w3.org/TR/webdriver-bidi/#command-emulation-setScreenSettingsOverride). OriginWeave's current presentation profile has no screen.availWidth/screen.availHeight (or equivalent available-screen-area) field, so this planner can change a page-observable fingerprint surface that is neither selected nor digest-bound by the profile. The existing fail-closed treatment of color depth is correct but does not cover this additional observable.
Please keep complete PresentationSurface::Screen fail closed and repair this as an explicit contract rather than treating command ACK as evidence: either model/bind the available-screen-area semantics in the presentation identity before the command is part of the reusable profile-derived plan, or keep setScreenSettingsOverride behind a separately explicit partial intent until that model exists. Add a regression proving the reusable profile-derived planner cannot silently mutate an unmodelled available-screen surface. No runtime revision repin is needed for this finding. COMMENT only; not approval.

Buyer-visible gap
The runtime-qualified WebDriver BiDi 3 September 2026 Working Draft defines context-scoped
emulation.setScreenSettingsOverride, but onescreenArearectangle changes both total and available page-visible screen geometry. OriginWeaveScreenMetricsmodels width, height, and color depth but notscreen.availWidth/screen.availHeight; completePresentationSurface::Screenmust therefore remain fail closed, and the reusable presentation-profile plan must not silently schedule this mutation.This stack remains on #229 exact

The child then retainedWebDriverBidiScreenArea, opaqueWebDriverBidiScreenAreaOwnership, and witness-bearingSetScreenArea/ResetScreenArea, removed only the unreachable planner helpers, added no dead-code waiver or raw-context escape hatch, and recorded the decision in Proposed ADR 0113 plus focused doctoring/traceability.#311 exact

The staggered runner admission and later ordinary recovery were handed to canonical organization queue owner.github#712; no leaf retrigger, cancellation, no-op push, workflow mutation, or synthetic status was used.The inherited source enforces the intended boundary: reusable planning is viewport/DPR plus timezone only; screen-area command vocabulary requires a non-caller-mintable Browser Session ownership witness; no public screen-area planner exists until the canonical Browser Session lifecycle adds the mint transition and consuming path together; complete Screen admission remains fail closed while available-screen geometry and color depth are uncontrolled. The two prior CodeRabbit ownership/doctoring threads were answered against this inherited exact head and resolved; that thread state is finding-resolution evidence, not an independent approval.
This exact-head repository GREEN makes #310 eligible only for ordinary integration into its immediate stacked parent #229 if the live head/base remain unchanged. It is not protected-main shipment and does not bypass #229's own required CodeQL/review gates.
Browser acceptance remains separate
Repository GREEN here is not browser GREEN. #299 remains the pinned-Chromium evidence lane; presentation apply, page-observed target, native interaction/outcome, reset or owned destruction, original-baseline re-observation, and full session/profile cleanup must all be demonstrated in the actual browser path. Command vocabulary or ACK is not post-condition evidence.
No workflow/ruleset/secret mutation, self-approval, provider/model pin, sandbox weakening,
--no-sandbox, trial reduction, protected-main merge, tag, or release is part of this stack integration.
