Conversation
…t blocks #780's premise was unverified in-tree: both prior sightings of glue-cookie-notification-bar are labs.google (test_assets/debug_editor/buttons.json carries styled-components siblings, i.e. labs' React build; smoke_video_editor.py likewise), and yesterday's 2026-09-10 spike read 159 DOM samples on this exact host and project, found zero overlays and zero dialogs, and watched the click land 3/3. That spike never looked for a cookie bar, so it neither found nor excluded one. Measured today on the same profile and project, seventeen hours later: - the bar is present and visible 6/6, div#glue-cookie-notification-bar-1, position:fixed, z-index:1000, pointer-events:auto, spanning y 547-655 of a 655px viewport, served from gstatic /glue/cookienotificationbar/ - elementFromPoint over the settings trigger AND over the image submit returns span#glue-cookie-notification-bar-1-label in every rendered sample: 0/5 hit-testable - control arm, running the driver's own _dismiss_cookie_bar: bar gone, both controls hit-testable 4/4, one attempt, no error So the premise holds and is BROADER than #780 states -- it names only the settings trigger; the submit button is covered too. This does not contradict yesterday's 0/3: that spike declined to read a disappearance as transience, and named "a first visit after a Flow deployment" as the state it could not summon. This is that state. Two gaps recorded rather than papered over: the labs contrast arm failed (ci-probe is a moved account, so the labs URL redirected and the second arm re-measured the first), and the control arm consumed the state, so a re-run reads 0/N until Google re-prompts. Side finding: the bar's buttons are __accept then __reject in DOM order, so buttons.first accepts cookies on the operator's behalf. Rejecting unblocks identically.

…ot go (#780) Google's `glue` consent bar is `position: fixed` at `z-index: 1000` and Flow's composer is bottom-anchored in the same band, so the bar lands ON the settings trigger and on the image submit. Measured on `ci-probe`: 6/6 samples visible, `elementFromPoint` over both controls returning the bar's label span, 0/5 hit-testable -- on the same profile and project where the click had landed 3/3 seventeen hours earlier. Every image and video run on a re-prompted profile failed, before any submit, so nothing was billed. Reported by @stgmt in #780. The premise was unverified in-tree and I nearly rejected it: both prior sightings of this selector are labs.google, and the 2026-09-10 spike read 159 DOM samples on this exact host and found zero overlays. That spike never looked for a cookie bar. It was right to record its 0/3 as unmeasured rather than as transience, and it named "a first visit after a Flow deployment" as the state it could not summon. This is that state. Two changes, and the second is what lets the first stay small: 1. `_open_pane` clears the bar before its first click -- the one place the image and the video path meet, so neither caller carries its own copy. It REJECTS rather than accepts: both buttons remove the bar and unblock the composer identically, and only one of them answers a consent question on the operator's behalf. `__accept` is first in DOM order, so anything reaching for "the first button" takes Agree. 2. The click post-mortem now names the thing on top instead of its inner node. #776's occluder allowlist matched `cdk|mat|mdc|flow` class prefixes on whatever `elementFromPoint` returned -- but a consent bar puts an unnamed label span there and keeps its identity in an `id` the allowlist deliberately drops, so the message read `it is covered by span`. It now adds Google's `glue` prefix and climbs to the nearest ancestor that names itself. The `id` is still never echoed. Because (2) makes a stuck bar self-describing, (1) is deliberately best-effort: it does not raise. A bar that refuses to go falls through to the post-mortem and is reported as `div.glue-cookie-notification-bar`. One attributed failure beats two competing ones, and it is the smaller diff. Verification: - offline: 4234 passed, 24 skipped. The fake page's strict selector allowlist caught this change immediately and now models the bar, refusing the trigger click while it is up -- the real geometry, reproduced rather than assumed. - e2e: 8/8 in `tests/e2e/test_click_attribution_bdd.py`, two of them new. Control run with the src change stashed: both new scenarios fail, and the failure prints the exact `it is covered by span` this commit removes. - live, $0: `ensure_editor` -> `apply_image_settings` -> close against real Flow on `ci-probe`. Editor ready in 2 s, model and aspect bound, pane closed. This proves the new call is harmless on the ordinary bar-free page, which is the regression risk the change introduces. NOT verified, and it cannot be here: the cure against a live bar. The spike's control arm consumed the consent on the only profile that had it, and a second profile (`denon82`) never reached the editor -- both arms redirected to `/about`. So prevalence is unmeasured and the live cure is proven only in the browser, against the measured DOM shape. MCP parity: no CLI surface change, no new option, no new output shape. Both doors share this transport, and the improved detail reaches the queued path through the typed-error branch #778 established.

…lick no click Three accuracy fixes from CodeRabbit on #782, all of the same kind this session has been enforcing elsewhere -- an artifact stating something that was not measured. - KNOWN_ISSUES said the bar "arrives whenever Google re-prompts for consent, not once per profile". That is an inference from n=1. One account was observed blocked and one observed already-consented; the recurrence pattern is unknown and now says so. - the spike's own JSON recorded "the bar is observed, never clicked" even under --dismiss, which clicks a consent button. It now reports the control arm and carries a dismiss_arm flag. - the spike's side finding described buttons.first in the present tense. It was PR #781's behaviour and it is what this spike's control arm ran, so it accepted on ci-probe; the shipped fix anchors on __reject and the control arm imports the driver, so re-running it today measures what ships.

Summary
Google's
glueconsent bar isposition: fixedatz-index: 1000, and Flow's composer is bottom-anchored in the same band. The bar therefore lands on the settings trigger and on the image submit button, and every image and video run onflow.google.comfails until it goes. It fails before any submit, so nothing is billed.Reported by @stgmt in #780. Their PR #781 carries a working dismissal bundled with a host-routing change and a diagnostics layer; this takes only the dismissal, because the surface is broken now. Review of the rest is on #781.
The measurement
Spiked before reviewing, because the premise was unverified in-tree and I nearly rejected it. Both prior sightings of
glue-cookie-notification-barin this repo are labs.google, and the 2026-09-10 spike read 159 DOM samples on this exact host and project and watched the click land 3/3. That spike never looked for a cookie bar.Seventeen hours later, same profile, same project:
The 2026-09-10 spike was right to record its 0/3 as unmeasured rather than as transience, and it named "a first visit after a Flow deployment" as the state it could not summon on demand. This is that state, arriving on its own.
Writeup:

1.
_open_paneclears the bar before its first click. That is the one place the image and video paths meet, so neither caller carries a copy. It rejects rather than accepts: both buttons remove the bar and unblock the composer identically, and only one answers a consent question for the operator.__acceptis first in DOM order, so anything reaching for "the first button" takes Agree.2. The click post-mortem names the thing on top, not its inner node. #776's occluder allowlist matched
cdk|mat|mdc|flowclass prefixes on whateverelementFromPointreturned. A consent bar puts an unnamed label span there and keeps its identity in anidthe allowlist deliberately drops, so a blocked user on 0.73.0 gets:It now adds Google's
glueprefix and climbs to the nearest ancestor that names itself, reportingdiv.glue-cookie-notification-bar. Unchanged for the CDK overlays that already worked; theidis still never echoed.Because (2) makes a stuck bar self-describing, (1) is deliberately best-effort and does not raise. A bar that refuses to go falls through to the post-mortem. One attributed failure beats two competing ones, and it is the smaller diff.
Verification

Control run with the src change stashed: both new scenarios fail, and the failure prints the exactit is covered by spanthis PR removes.ensure_editor→apply_image_settings→ close against real Flow onci-probe. Editor ready in 2 s, model and aspect bound, pane closed. This proves the new call is harmless on the ordinary bar-free page, which is the regression risk the change introduces.ruff,ruff format,pyright src(0 errors), and all six hygiene gates including the website mirror.What is NOT verified
The cure against a live bar. The spike's control arm consumed the consent on the only profile that had it, and a second profile (
denon82) never reached the editor — both arms redirected to/about. So the live cure is proven in the browser against the measured DOM shape, not against a live bar, and prevalence is unmeasured: one account confirmed blocked, one confirmed already-consented.This is recorded rather than claimed. What would settle it: the same probe on several profiles that reach the editor, next time Google re-prompts.
MCP parity
No CLI surface change, no new option, no new output shape. Both doors share this transport, and the improved error detail reaches the queued path through the typed-error branch #778 established.
