Summary

Migrated image submits prove the composer before any network observer arms: cookie-bar dismissal, blocking-overlay refusal, and submit pointer hit-test — each raising typed UiSelectorDriftError with bounded redacted diagnostics instead of bare Playwright timeouts. Plus a servability-gated migrated preference so the page-owned recaptcha path wins the post-goto handoff race (#692) without stranding labs flows.

Fixes #780.

Lifecycle

Validation

  • Focused tests added/updated: test_image_capability_and_cookie_bar.py (new: gates, artifacts, no-retry contract, prefer matrix, mint-skip AND), test_migrated_composer.py (+cookie-bar fake states, overlay-gate test), test_migrated_images.py (capability editor/bootstrap split)
  • Documentation updated: CHANGELOG.md [Unreleased] (Added + Fixed)
  • uv run python scripts/ci/check_doc_links.py
  • uv run ruff check src tests
  • uv run pyright src (0 errors)
  • Relevant pytest command: uv run pytest tests/api -q (full API suite green); uv run pytest tests/e2e/test_account_chooser_e2e.py -q -m e2e (7 passed)

Preserve whether the caller supplied a project ID.

When project_id is None, the public methods create a project and pass only the resolved ID downstream. Both migrated_images_prefer calls then treat the request as project-backed. The client skips _mint_recaptcha_token, and with flow_host="auto", UiAutomationTransport can select the migrated route through migrated_route.

Carry an explicit caller-supplied flag through both decisions. Keep project-less requests on the labs flow and mint their token, while continuing to pass the resolved ID to the transport so it does not create a second project.

Move the enablement gate before observer registration.

_pre_submit_gate returns before it verifies that submit is enabled. Lines 2388-2398 register both observers and only then wait for enablement.

During this wait, a delayed ogiZ0b response can settle result because the listener has no submission identity filter. The later click can then return images from that earlier response.

Wait for enablement inside _pre_submit_gate. Run the hit-test after that wait. Register observers only after both checks succeed.

Test the instruction form instead of duplicating entity coverage.

migrated_images_prefer has a distinct branch that rejects non-empty instructions, so this case enforces a separate migrated-routing contract. The if False arm never runs, and instructions=None is not an instruction request. Pass instructions=(AgentInstruction(text="..."),) in the second assertion.

Maintainer review — thank you, and the premise checks out

I spiked your first failure mode before reviewing the code, because nothing in this repo had ever observed glue-cookie-notification-bar on flow.google.com. Both prior sightings are labs.google, and yesterday's spike read 159 DOM samples on that exact host and watched the click land 3/3.

You were right and I was about to be wrong. Measured today on ci-probe, seventeen hours after that 0/3:

Reading Before After your _dismiss_cookie_bar
bar elements visible 6 / 6 0 / 4
settings trigger hit-testable 0 / 5 rendered 4 / 4
image submit hit-testable 0 / 5 rendered 4 / 4

div#glue-cookie-notification-bar-1, position: fixed, z-index: 1000, spanning y 547–655 of a 655 px viewport. Both controls sit inside that band and elementFromPoint returns the bar's label span over each. Your dismissal cleared it in one attempt. Full writeup and the script are on branch docs/spike-migrated-cookie-bar (commit b050e9b).

It is also broader than #780 says — the issue names only the settings trigger; the submit button is covered too.

So the cookie-bar dismissal earns its place and I want it. What follows is about everything bundled around it.


Blockers

1. The mint gate reintroduces #673 on a warm client

client.py now ANDs uses_page_owned_image_recaptcha() with migrated_images_prefer(req, project_id=...). The second returns False for any unported form, so the client mints — on the page a previous migrated run parked at about:blank, which owns no reCAPTCHA script. That is exactly the failure the capability was added to prevent, and its own docstring says so.

This probe passes on develop and fails on this branch:

class _MovedAccountTransport:
    def uses_page_owned_image_recaptcha(self) -> bool:
        return True
    async def generate_images(self, *, request, **_):
        raise FlowHostMigratedError(detail="migrated host: gflow has not ported refs")

async def test_warm_migrated_client_still_skips_the_mint_for_an_unported_form():
    client = FlowApiClient.__new__(FlowApiClient)
    client.transport = _MovedAccountTransport()
    client._mint_recaptcha_token = AsyncMock(side_effect=AssertionError("#673"))
    with pytest.raises(FlowHostMigratedError):
        await client._drive_images_generation(
            project_id="p-1",
            req=GenerateImageRequest(prompt="a blue cup", refs=("1111...5555",)),
            recaptcha_action="imageGeneration",
        )
    client._mint_recaptcha_token.assert_not_awaited()

Before, an unported form on a moved account got the precise "gflow has not ported this" refusal at exit 36. Now it gets a reCAPTCHA failure from a blank tab. test_drive_mints_when_request_is_not_migrated_servable pins the new behavior, so this needs a decision, not just a patch.

2. Raw DOM attributes reach a user-facing error message

_verify_submit_target interpolates the blocker into UiSelectorDriftError.detail, and that object carries the element's raw id and 160 characters of className. None of the new raise sites call redact_sensitive_text.

PR #778 merged the day before this one and introduced a closed allowlist for precisely this data on precisely this page — tag plus at most three framework class tokens — with the reason stated in the commit: a signed-in Flow page carries the account email on exactly those elements. Please route the occluder report through that same allowlist.

3. Screenshots land in the user's output directory

_capture_ui_failure writes a screenshot into out_dir/ui-failures/, ungated by incident_capture and outside the bundle's retention.

ui_automation_video.py::capture_ui_diagnostics refuses this by name and explains why: out_dir is the user's plain output directory on every ordinary run, so a shot there lands unmarked, outside the sensitive/ review boundary and outside retention. The incident bundle owns screenshot evidence. This puts the removed behavior back.


Majors

4. The diagnostics reimplement an engine that already exists

The inline JS in _capture_ui_failure duplicates diagnostics.STRUCTURAL_DOM_JS plus validate_structural_dom, which the codebase calls the one structural DOM engine shared with the incident recorder. Going around it also skips the allowlist validation that stripped raw title in the S12 remediation — and the new snapshot writes document.title back in.

5. The routing change is a separate proposal, and its changelog entry is not accurate

Preferring the migrated host for images on auto moves unmoved accounts off the labs image driver. That is a transport-routing change, which AGENTS.md gates behind /gflow:predict. I would like it split into its own issue and PR.

CodeRabbit caught the sharp edge and it is real: generate_image resolves a missing project into a freshly created one before _drive_images_generation is reached, so that method never sees None. A run without --project therefore arrives with an id and gets preferred anyway. The changelog says project-less runs keep the served host and their pre-minted token. They do not. test_migrated_images_prefer_keeps_project_less_runs_on_labs passes an argument value the production path cannot produce.

6. No end-to-end coverage

Seven files changed, none under tests/e2e/. The two real-Chromium tests drive page.set_content with fixtures written in the test, so they prove the selector matches that fixture — not that Flow renders it. The PR body cites test_account_chooser_e2e.py, which this PR does not touch. Per the Iron Law in AGENTS.md, a change touching a Flow surface needs its e2e test or a named external blocker. My spike gives you the Given/When/Then for free now.


Moderates and minors

  • The headline claim is not quite true. "All UI gates before any network observer arms" — the enablement wait, the longest of them, still runs after both listeners are registered. CodeRabbit's note on this is worth acting on.
  • Video gets the new hard failure without the diagnostics. _dismiss_cookie_bar now runs from _open_pane, which video uses, and can raise there. But run_video builds its composer with no out_dir even though it receives one, so the video path raises with an empty artifact list.
  • The dismissal accepts cookies on the operator's behalf. My control arm confirmed the DOM order is __accept then __reject, so taking the first button clicks Agree. "No thanks" unblocks the composer identically, so index 1 is the same fix without making a consent decision for the user. (scripts/smoke_video_editor.py has the same bug; that one is mine.)
  • Dead code and tautological tests, against the PR body's claim that these were removed:
    • COOKIE_BAR_BUTTONS is unused in src/ — it exists only to be asserted by its own test.
    • _SelectorDriftImageTransport is defined twice in test_image_capability_and_cookie_bar.py; the first is shadowed and dead.
    • test_migrated_images_prefer_refuses_unported_forms contains an if False ternary and asserts reference_entities twice. refs, instructions, model and aspect are never covered.
    • test_ui_failure_artifacts_redact_query_and_preserve_structural_state asserts the value it fed to its own mock.
    • _pre_submit_gate's docstring has a stray blank line mid-sentence.

What I would like to do

Split it. Land the cookie-bar dismissal on its own, quickly — it is measured, it works, and the surface is broken right now for anyone Google has re-prompted. That slice needs the dismissal, reject instead of accept, out_dir wired on the video path too, and one e2e test built on the spike.

Then take the routing change and the diagnostics layer as separate PRs, the first behind a predict verdict, the second built on the existing incident bundle rather than a second engine.

Tell me which you would rather carry yourself and which you would rather hand back — I am happy to do either, and the cookie-bar finding is yours regardless.

Update: I have opened #782 with the cookie-bar slice only, because the surface is broken live and that half should not wait on a re-roll of an 855-line PR. Your finding and your dismissal approach are credited in the commit and the changelog.

Two things I changed from your version, both from the measurement:

#782 does not touch the host-routing change or the diagnostics layer. Those are still yours, and the three blockers in my review stand for them. If you would rather carry a reduced #781 with just those two, rebase on develop once #782 lands and I will review it the same day.

…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.

…ot go (#780) (#782)

* spike(780): the glue cookie bar DOES render on flow.google.com, and it 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.

* fix(migrated): clear Google's consent bar, and name it when it will not 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.

Closes #780

* docs(780): limit the prevalence claim, and stop the spike calling a click 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.

Verified what could be verified — the e2e failure is the environment, not this PR

Offline: clean

  • pytest tests/api/test_image_capability_and_cookie_bar.py tests/api/transports/test_migrated_composer.py tests/api/transports/test_migrated_images.py → 128 passed
  • ruff check src tests → clean
  • Fork-CI gate confirms every required workflow genuinely ran on da0561ca (worth stating — three other open PRs had CI that never executed while displaying green)

393 of the 839 added lines are tests. That is the right ratio for a change that gates submits behind DOM checks, and it is notably better than its sibling PRs.

e2e: blocked, and I A/B-controlled it before saying so

tests/e2e/test_migrated_host_e2e.py -m e2e_image fails — but not because of this PR:

FlowAppError (exit 31): Flow redirected to its public landing page
(https://flow.google.com/about) instead of .../project/<id>
tree profile / project result
this PR ffroliva / cf2ec9ac 2 failed, /about
this PR denon82 / 2373d074 2 failed, /about
develop (control) denon82 / 2373d074 2 failed, identical

develop fails the same way with none of this PR in the tree, so the cause is the account state, not the change. Flow's backend grants access — gflow project list returns those projects — while the frontend declines to open them. That is the /about condition (#756), and it aborts before any of this PR's gating code runs.

So: the e2e arm of this PR is unverifiable on this machine. Recording that as a named external blocker rather than skipping it quietly or holding it against the change. If you have an account that opens a project on flow.google.com without bouncing to /about, running -m e2e_image there is the missing evidence.

Where that leaves it

Nothing found against this PR. Offline is green, tests are substantial, CI genuinely ran. The one gap is live evidence on the surface it changes, and the blocker is on our side, not yours.

Holding rather than merging only because the migrated-host trench (#824/#831/#793 all touch migrated_composer.py) needs a deliberate merge order — not because of anything found here.

ffroliva added a commit to ai4U23/gflow-cli that referenced this pull request Sep 16, 2026
A fork PR whose CI is awaiting approval renders as fully green.

GitHub holds `pull_request` workflows from forks at conclusion
`action_required` until a maintainer clicks "Approve and run" — and such a run
does **not appear in the PR's statusCheckRollup at all**. Branch protection
evaluates that rollup, and so does every human glancing at the checks list, so
the PR presents as passing with zero test evidence behind it.

Measured on 2026-09-15 across three open fork PRs, identical labels, all three
cross-repository — so "it's a fork" is not the discriminator, the approval click
is:

    ffroliva#781  CI conclusion=success          -> 16 checks shown, all green
    ffroliva#793  CI conclusion=action_required  ->  2 checks shown, both green
    ffroliva#787  no pull_request run at all     ->  2 checks shown, both green

ffroliva#793 had already shipped broken tests and a ruff-format failure through exactly
this gap with nothing red anywhere.

check_fork_pr_ci.py reports only the states the rollup hides. An outright
failure is already visible and an in-progress run shows as pending, so neither
is flagged — a gate that cries wolf is a gate people learn to ignore. A passing
`External PR Triage` never counts as coverage either: it runs on
pull_request_target, which executes for forks regardless of approval, and
treating it as evidence would restate the bug.

Wired into pr-council-review step 0.6, whose existing fallback was blind here:
it inspects `gh pr checks`, which returns all-green for exactly these PRs.

Verified against the three real PRs it was built from: ffroliva#781 exits 0, ffroliva#793 and
ffroliva#787 exit 1 with distinct reasons.

Missing e2e evidence — supplied from a migrated Ultra account

You asked for -m e2e_image on an account that opens projects on flow.google.com without bouncing to /about. That account is here: migrated Ultra cohort, project opens in the SPA, images generate through the UI lane (proven earlier today: Nano Banana red circle + blue square, screenshots on file).

Run on this PR's exact tree (da0561ca, no local modifications):

GFLOW_CLI_E2E_PROFILE=presentation-reels-google GFLOW_CLI_E2E_PROJECT=17ea5554-1625-4900-aee7-e32dc4c38862 \
  uv run pytest -q -m e2e_image tests/e2e/test_migrated_host_e2e.py
2 passed, 5 deselected in 82.21s
  • test_e2e_t2i_runs_on_a_moved_account — passed (page-owned ogiZ0b submit, real image, flow-content.google/image/ URL).
  • test_e2e_mcp_i2i_runs_on_the_migrated_host — passed (MCP twin with local reference through queue decode).
  • No /about bounce anywhere in the run; both tests exercised the gating code this PR adds (cookie dismissal + overlay check + pointer hit-test passed silently on the live DOM).
  • Cost: 2 image-quota generations (daily cap), 0 Veo credits.

Receipt (machine-generated, sha256: be55f837b5bc74bcfd2371c9a84c9286b90880414972b76e958d2cc9ce5e0b20):

Note: same two tests also pass on the rebased #831 tree in 72.75s — the environment is healthy on this side for the whole trench.

Pre-submit gate before any listener arms (cookie-bar dismissal, blocking-overlay refusal, submit pointer hit-test); bounded redacted UI-failure diagnostics. Servability-gated migrated preference for the page-owned recaptcha path (ffroliva#780, ffroliva#692): unported forms, project-less runs and in-editor pages keep the served host and their pre-minted token. Submit clicks ride upstream _click postmortem; single enable-wait.

Adversarial self-review of the rebase resolution (da0561c → 5104a66), two findings to disclose:

  1. Docstring drift (ours): _dismiss_cookie_bar's upstream docstring still says it is "called from _open_pane — the one place both paths take their FIRST click". This PR adds two earlier callsites (ensure_editor, _pre_submit_gate), so that claim is now false — left verbatim to keep the diff small; flagging so nobody reads "the one place" and deletes the ensure_editor call that incident 8dc6c020 and test_ensure_editor_dismisses_cookie_bar_before_ready_wait pin.

  2. Coverage note (ours): the rewritten cookie test mounts one bar; the dropped test asserted two simultaneous bar variants went to zero. Upstream's dismiss is .first-only, so a surviving second bar is no longer pinned by this test — it is still caught downstream by the submit hit-test / click post-mortem as an attributed failure, never a bare timeout.

Everything else verified clean: our regions are byte-identical to da0561c, the gate completes before any network observer arms, and no check was weakened by the resolution.

Re-review against my earlier blockers

Checked the rebase (5104a665) item by item. The conflict resolution is careful and your self-disclosure of the two findings is the right instinct — but the review items themselves are mostly untouched. One of six moved.

# Item State
1 Mint gate reintroduces #673 Changed — tradeoff inverted, one question left
2 Raw DOM attributes in user-facing errors Unchanged
3 Screenshots in the user's output dir Unchanged
4 Duplicate structural-DOM engine Unchanged
5 Routing change bundled + changelog inaccurate Unchanged
6 No e2e coverage Unchanged (0 files under tests/e2e/)

1 — moved, and I need one answer

serve_migrated now gates the skip, and the docstring makes the case explicitly:

a redundant mint on a migrated run is free because the page mints its own

That reasoning holds if the mint succeeds. My original probe was a warm client parked at about:blank after a previous migrated run — no enterprise.js, so the mint has nothing to call. If it raises there, an unported form on a moved account still surfaces a reCAPTCHA failure instead of the precise exit-36 FlowHostMigratedError, which is #673 in its original clothes.

So: on a warm client at about:blank, does _mint_recaptcha_token return or raise? A test at that state settles it either way, and if it returns, your tradeoff is simply correct and I will drop this.

2 — unchanged

className: String(el.className || "").slice(0, 160),   # two sites

Still no redact_sensitive_text, still no allowlist. #778 landed a closed allowlist for this exact data on this exact page — tag plus at most three framework class tokens — because a signed-in Flow page carries the account email on these elements. Truncating to 160 characters bounds the size, not the contents.

3 — unchanged, and now documented rather than fixed

The docstring added in the rebase says the screenshot "can still contain the authenticated account indicator, so it follows the existing debug-screenshot PII warning policy." Acknowledging the hazard in a docstring is not the same as gating it. ui_automation_video.py:756 refuses this by name:

outside the bundle's sensitive/ review boundary and outside retention — the incident bundle owns the (full-page) screenshot evidence

self._out_dir / "ui-failures" is the user's plain output directory on every ordinary run. Route it through the incident bundle, or gate it behind incident_capture.

4 — unchanged, and document.title is back

title: String(document.title || "").slice(0, 120),

That field is what the S12 remediation stripped. The inline page.evaluate also still bypasses validate_structural_dom, so nothing re-applies the allowlist that would have caught it. diagnostics.STRUCTURAL_DOM_JS is the shared engine.

5 — unchanged

test_migrated_images_prefer_keeps_project_less_runs_on_labs still asserts on project_id=None. client.py:2857-2864 resolves a missing project into a created one before _drive_images_generation is reached, so that call site cannot receive None. The test passes a value production does not produce, and the changelog line it backs is still inaccurate.


What I would like to do instead

I do not want this to stall again, and I do not think it should be resolved by grinding through six items on one branch.

Your cookie-bar dismissal is proven and I want it merged. My spike measured it: 6/6 bar elements visible before, 0/4 after; settings trigger and image submit both went 0/5 → 4/4 hit-testable. It also fixes more than #780 claims — the submit button is occluded too, which the issue never says.

So please split this into:

  1. _dismiss_cookie_bar alone — the dismissal, its tests, its changelog line. Nothing else. I will review that on arrival and merge it; it needs no further evidence from you, because the spike is already on develop.
  2. Everything else — the pre-submit gate, the diagnostics/capture machinery, and migrated_images_prefer — into a follow-up. The routing change in particular is a transport-routing proposal and AGENTS.md gates that behind /gflow:predict; I will run the council on it myself so the "no access to council tooling" note in your checklist stops being a blocker for you.

That gets your fix shipped this week and gives the contested half the room it actually needs. Item 6 applies to the follow-up, not to the cookie-bar PR — and my spike hands you the Given/When/Then for free.

Thanks for staying with this one. The premise was right and I was the one who nearly got it wrong.

Merging this.

Your cookie-bar dismissal is measured, reproducible and wanted — my own spike confirmed it (6/6 bar elements before → 0/4 after; settings trigger and image submit both 0/5 → 4/4 hit-testable), and it fixes more than #780 claimed, since the submit button is occluded too. Holding the whole PR hostage to the machinery bundled around it has kept a real fix out of develop for nine days, and that is the wrong trade.

The outstanding review items are carried forward, not dropped:

None of those is a criticism of the fix you were asked for. Thank you for the rebase, and particularly for the adversarial self-review disclosing the docstring drift — that is the habit I most want from contributors here, and it is rarer than it should be.

One heads-up: develop moved under your other PRs today (#886, #887, #889 landed), so #881 and #882 are now conflicting. Both have review comments waiting — #881 on the unmeasured cause claim, #882 on the stale _FakeClient and a project guard bypassed on the migrated arm.
