Summary

This PR adds two user-requested capabilities across CLI, MCP, and transport layers:

  1. Explicit video resolution control (--resolution [360p|720p]):

    • Available on gflow video t2v, i2v, r2v and MCP tool gflow_generate_video.
    • Wired into GenerateVideoRequest DTO, worker codec, and MigratedComposer._select_resolution.
    • Resolves an issue where models like omni-flash default automatically to 360p without user control, enabling explicit 720p (or 360p) selection.
  2. Nano Banana 2 Lite model support (--model nano2-lite):

    • Discovered and mapped Google's internal wire model string HARBOR_SEAL.
    • Available in gflow image t2i, i2i, and batch.
    • Enums and catalog updated (gflow models cleanly displays HARBOR_SEAL | nano2-lite).

Verification & Quality Gates

  • Unit & Integration tests: 2506 passed across tests/api/, tests/mcp/, tests/cli/, tests/flow_selectors/.
  • Parity tests: tests/mcp/test_cli_parity.py and tests/mcp/test_server.py passed with 0 violations.
  • Hygiene & Lint:
    • check_repo_hygiene.py, check_doc_links.py, check_website_docs_pii.py, generate_website_docs.py --check, check_council_memory.py all clean.
    • ruff check src tests & ruff format --check src tests clean.
    • pyright src clean (0 errors, 0 warnings).
  • Live verification:
    • Verified image t2i "un croquis..." --model nano2-lite: Successfully generated 768x1376 JPEG in ~12 seconds.

Summary by CodeRabbit

  • New Features

    • Video generation commands and the MCP video tool now support selecting 360p or 720p on compatible models; omitting the option keeps Flow’s default resolution.
    • Added Nano Banana 2 Lite as an image-generation model, available with the nano2-lite alias.
    • Added an MCP tool for downloading previously generated media.
  • Improvements

    • Image-to-video workflows now support end frames, and uploaded frame and reference images use unique filenames.
    • Documentation now covers the new options and tools, along with updated guidance for Flow-host behavior and project creation.

- Add --resolution [360p|720p] to video generation commands (t2v, i2v, r2v)
  and MCP tool gflow_generate_video, preventing unintended defaults on omni-flash.
- Wire resolution selection into MigratedComposer._select_resolution and
  GenerateVideoRequest DTO.
- Add nano2-lite model alias for image generation (t2i, i2i, batch) mapped
  to Google's HARBOR_SEAL wire model.
- Update documentation (USAGE.md, MCP.md, CHANGELOG.md) and tests.

📝 Walkthrough

Walkthrough

The changes add optional video resolution selection, register Nano Banana 2 Lite as an image model, update migrated-composer handling, and extend MCP profile operations with locking and media recovery. Documentation also adds CLI references and updates host, recovery, and upgrade guidance.

Changes

Video and image generation

Layer / File(s) Summary
Video resolution request and option flow
src/gflow_cli/api/video.py, src/gflow_cli/cli_video.py, src/gflow_cli/worker/codec.py, src/gflow_cli/mcp/tools.py, tests/api/test_video.py, tests/e2e/test_migrated_host_e2e.py, docs/MCP.md, docs/USAGE.md, website/docs/USAGE.md, CHANGELOG.md
The CLI, API, worker payload, and MCP video tool accept optional 360p or 720p resolution. Request validation rejects other values, and tests cover API validation and migrated-host requests.
Resolution selection across video transports
src/gflow_cli/api/transports/migrated_composer.py, src/gflow_cli/api/transports/ui_automation_video.py, tests/api/transports/test_migrated_composer.py, tests/api/transports/test_ui_automation_video.py
The migrated composer selects and verifies the requested resolution. The Labs route rejects explicit resolution before submission.
Nano Banana 2 Lite model registration
src/gflow_cli/api/image.py, src/gflow_cli/api/transports/migrated_composer.py, src/gflow_cli/api/transports/ui_automation.py, src/gflow_cli/image_batch.py, tests/api/test_image.py, tests/api/transports/test_migrated_images.py, tests/api/transports/test_ui_automation.py, tests/flow_selectors/test_model_governance.py, tests/e2e/test_migrated_host_e2e.py, docs/USAGE.md, website/docs/USAGE.md, CHANGELOG.md
The image API, batch validation, and transport selectors recognize the nano2-lite alias as HARBOR_SEAL. Tests cover aliases, model matching, and migrated-host selection.
Migrated-composer frame and picker interactions
src/gflow_cli/api/transports/migrated_composer.py, tests/api/transports/test_migrated_composer.py, docs/USAGE.md, src/gflow_cli/mcp/tools.py, website/docs/MCP.md
The migrated-composer tests cover run-unique upload names, picker confirmation, end-frame attachment, interpolation requests, agent-only composers, and submission diagnostics. Documentation describes related migrated-host behavior.

MCP profile operations

Layer / File(s) Summary
Serialize MCP operations by profile
src/gflow_cli/mcp/tools.py, website/docs/MCP.md
A per-event-loop lock is used by MCP operations for the resolved profile. The documentation describes same-profile request serialization.
MCP media recovery tool
src/gflow_cli/mcp/tools.py, docs/USAGE.md, website/docs/MCP.md
The exported gflow_download_media tool accepts a media ID and optional output directory and profile, then returns recovered media metadata. The docs describe recovery behavior and retries.
Profile status and MCP service guidance
src/gflow_cli/mcp/tools.py, website/docs/MCP.md, docs/USAGE.md
gflow_auth_status returns a non-retryable 409 when the profile marker is missing. MCP documentation covers credit limitations, server setup, authentication, concurrency, and troubleshooting.

CLI reference and operational guidance

Layer / File(s) Summary
Handle missing chain dependencies
src/gflow_cli/cli_video.py, docs/USAGE.md
The chain command converts import failures into FrameExtractionError. The usage guide documents the Pillow dependency and the associated exit code.
CLI command and recovery references
docs/USAGE.md
The guide adds the gflow docs command, its output options, and documentation of media recovery behavior and error codes.
Upgrade and error guidance
docs/USAGE.md
The guide updates upgrade precautions, import-failure guidance, and exit-code descriptions, including remediation hints and additional Flow account conditions.

Estimated code review effort: 4 (Complex) | ~50 minutes

Add nano2-lite to the migrated flow.google.com support note.

The migrated transport maps nano2-lite to HARBOR_SEAL, matches the Nano Banana 2 Lite menu entry, and sends it through run_images. Both support notes list only nano2 and nano-pro, which gives users incorrect availability guidance. Update docs/USAGE.md and website/docs/USAGE.md.

The command-specific sections document this option, but the shared t2v/i2v/r2v summary in docs/USAGE.md and website/docs/USAGE.md omits it. This makes the quick reference incomplete for users who rely on the shared summary. Include the omni-flash restriction.

Use a structural anchor for the resolution radio.

_select_resolution() scopes to [role='radio'] but then selects by has_text. This violates the locale-invariant selector contract. A changed or localized label can make the lookup empty and raise ConfigurationError; use stable structural metadata instead. ModelMenuMatcher("Nano Banana 2 Lite") is a Python-side matcher over structurally selected menu items, not a DOM selector.

Replace the text-based selector with a structural selector.

[role='menuitem']:has-text('Nano Banana 2 Lite') depends on the English menu label. A localized menu can produce zero matches, so Model.HARBOR_SEAL becomes unavailable. Use a stable, locale-independent structural marker for this option.

As per coding guidelines, selectors in src/gflow_cli/api/transports/** must be 100% language-agnostic and anchor exclusively on structural properties.

Reject resolution for explicit non-VideoModel.OMNI_FLASH requests. _validate_resolution() accepts valid strings, while _validate_model_capabilities() validates only duration. MigratedComposer.apply_video_settings() then calls _select_resolution(); non-Omni models have no matching row, so it raises ConfigurationError before prompt submission. Add this compatibility check to GenerateVideoRequest, and retain the separate malformed-value check.

Validate resolution before rate-limit acquisition.

When an invalid request passes _rate_limiter.acquire(), _build_video_payload stores values such as "360" or "1080p" in the queue. Queue decoding then constructs GenerateVideoRequest, which rejects the value and marks the task failed. The request has already consumed a token and created a failed queue task. Reject values other than "360p" and "720p" before _rate_limiter.acquire().

Maintainer review — thanks, and a note on what CI did not tell you

Your checks show 2/2, not 15/16. Only the labeller workflows ran; the test matrix, SonarCloud and the hygiene gates never executed on this PR. So I ran them locally against your branch merged onto current develop:

Gate Result
ruff check / ruff format --check clean, 467 files
pyright src 0 errors
pytest -m "not live and not e2e and not smoke" 4241 passed, 24 skipped

Your gate claims hold. The findings below are things the gates cannot see.

Two genuine positives before the list: the MCP twin is done properly (mcp/tools.py and worker/codec.py both move with the CLI flag, which external PRs usually miss), and _select_resolution runs inside apply_video_settings, so an unsupported combination fails before any submit and costs nothing. That is the right place for it.


Blockers

1. It reverses a consent decision made yesterday, and the comment above it still says why not

_dismiss_cookie_bar now falls back reject → accept → bar.locator("button").first. I measured the bar's DOM order on 2026-09-11: __accept is first. So two of those three branches accept cookies on the operator's behalf.

The docstring immediately above COOKIE_BAR_REJECT, three lines up in the same file, still reads:

REJECT, not accept. Both buttons remove the bar and unblock the composer identically, and only one of them answers a consent question on the operator's behalf.

The code below it now does the thing the comment forbids. That is the failure shape this repo keeps writing retrospectives about.

It is also not mentioned anywhere in the PR description, and it is speculative: __reject was present on every bar observed across three profiles and a clean browser context. If you have a capture where reject is absent, I want to see it — otherwise please drop the fallback and let the click post-mortem name a bar that will not go, which is what it is there for.

2. A raw Flow response body is logged unredacted

log.warning("migrated.image_submit_unparsed_reply", ..., text_head=text[:300])

That is the first 300 characters of an ogiZ0b reply body. I checked observability.py: the structlog processor chain is merge_contextvars, add_log_level, timestamper, StackInfoRenderer, exc_renderer, renderer. There is no redaction processor, so the field prints verbatim to stderr and into --json logs.

That body carries the prompt and media ids, and the 300-char window reaches into the payload. It fires on the failure path, which is exactly when someone pastes their output into an issue — the scenario #777 existed for. Please route it through redact_sensitive_text, or log parsed_rpcids and text_len only, which is what actually diagnoses an unparsed reply.


Majors

3. It removes a waiver without meeting the condition the waiver stated

_UNMODELLED_WAIVERS carried, in the repo's own words:

"🍌 Nano Banana 2 Lite" — Discovered 2026-08-26. A lower-tier image model we do not expose. Waived pending a capability spike (cost/quality) before we ship it.

This PR ships it and deletes the waiver. The evidence offered is one successful t2i, which shows the wire string works — not what the waiver asked for. A cost/quality comparison against nano2 is the gate this project wrote for itself on this exact model.

Credit where due: the governance test is what forced you to touch that list, and you updated it honestly rather than suppressing the test. I would like the spike behind it before the waiver goes.

4. An unmeasured value inherits a comment that says it was measured

_IMAGE_REFERENCE_CAP is introduced by:

Per-model I2I reference-image cap (live-observed). Flow silently keeps only the first N references when more are attached…

HARBOR_SEAL: 10 is added under that comment, but your live check was a t2i with no references. If Lite's real cap is lower — Imagen sits at 3 — a user attaching ten gets references silently dropped on a billed generation, which is precisely what the map exists to prevent. Either observe it, or start it at the conservative value with a note.


Moderate — and this one is not yours

5. A hidden model picker reads as "already selected" (pre-existing on develop)

I nearly filed this against your change and the control says otherwise, so I want to be exact.

Your rewrite wraps the picker guard in wait_for(state="visible") inside a bare except, re-raising only when count() is 0. I expected that to break the present-but-hidden case (#749's agent-mode shape). Probed in real Chromium, a button that is present under a bare hidden:

button count():    1
button visible():  False
migrated.image_model_already_selected  model='arrow_drop_downNano Banana 2' requested=NARWHAL
RESULT: returned with NO error — the guard did not fire

develop does exactly the same. So this is a latent defect, not a regression, and I will file it separately: a hidden picker makes --model silently read as already-satisfied, so a wrong-model generation gets billed and reported as success.

What your change does alter is latency — an absent picker now waits 4 s before raising instead of raising at once. Since you are already in this function, fixing the fallthrough here would be welcome, but it is not a condition of merging.


Minor

  • The branch is behind develop by two commits and CHANGELOG.md conflicts. Please merge develop in; nothing else conflicted when I tested it.
  • --resolution help says "supported on omni-flash" but the flag is offered unconditionally on all three video commands. That is fine given it fails pre-submit, but the help text reads like a guarantee. Consider naming the failure mode instead.

What I would like

Blockers 1 and 2 are small and mechanical — drop the accept fallback, and stop logging the body slice. Do those and rebase, and I will re-run the gates.

Majors 3 and 4 are about evidence rather than code: the capability spike the waiver asked for, and a reference-cap observation. If the spike is more than you want to take on, say so and I will run it — the feature is worth having and I would rather not stall it on something I can measure myself.

I ran the capability spike — major 3 from my review is settled, and it went further than expected. Branch docs/nano2-lite-capability-spike (commit 9f2b4c1), PR to follow.

The waiver's condition is half unanswerable, and that is not your fault

The repo's own cost/quota catalogue already establishes that image generation costs 0 Flow credits, and that "daily quota has no such oracle — it is observable only on exhaustion, via the 429". So the cost half of "cost/quality" cannot be measured without deliberately burning an account's day. I recorded that rather than inventing a number.

Quality: answered, and it supports shipping

Two arms, same prompt and aspect, both clean:

Arm Elapsed Dimensions Bytes
nano2-lite 20.3 s 1024×1024 428,799
nano2 25.4 s 1024×1024 384,036

No visible degradation on either; lite slightly more surface texture, nano2 slightly smoother. One prompt cannot rank two tiers and I have not tried to — but it does support the narrower claim the waiver needed: Lite is a working tier returning a usable image at full resolution.

Your wire string is independently corroborated. HARBOR_SEAL and Nano Banana 2 Lite both appear in HTrJv, Flow's own model catalogue for this account — a surface that is not our request echoed back. So the mapping is real.

Major 3 is cleared from my side. I would still like the cost gap carried forward rather than deleted along with the waiver, which the spec files already do.

What the spike found that changes how we read your live check

migrated_composer.py sets model_name_type=request.model.value — it echoes the request. So "generated a JPEG with --model nano2-lite" proves the UI did not error; it does not prove the tier bound. I went looking for a real oracle and there is not one:

Surface Model tokens Media ids
ogiZ0b submit reply none (both arms) —
HTrJv project load all six none
Zzl0ze project load none both

Nothing joins a media to its model. So the binding is unverifiable — by your check or mine. That is filed as #789 against develop, not against this PR; it is pre-existing and affects every tier.

Major 4 (the _IMAGE_REFERENCE_CAP entry documented as "live-observed") still stands, and the two blockers are unchanged.

Following up on the attribution point, because "unverifiable" was too strong and you deserve the actual boundary.

Is it resolvable? Not by anything I can reach — but the search is now wide, not narrow

My first pass searched two replies. I redid it with no filter: every batchexecute reply on a project load, 20–21 of them, checked for model tokens and for the two media ids I had just generated.

rpcid Size Model tokens Media ids
HTrJv 24,760 B all six none
Zzl0ze 41,906 B none both
tRARke 31,883 B none none
17 others (o30O0e, cPZSdc, as29s×5, …) 139–3,964 B none none

Zero replies contain both. The catalogue lists models; the media listing lists media; nothing joins them.

I also checked the page itself, since if Flow's UI shows it, the data is there. Two tier labels turned up — span.settings-summary and span.model-select-trigger-content — but the first appears on load, before anything is clicked, so both are the composer's own picker, not a property of any image.

What is still unmeasured: whether a tier label tracks the media you open. That is the one reading that would flip this, and I could not test it — thumbnail src does not carry the media id, and my generic selector matched zero tiles on the last run. Named rather than buried: it is the thread to pull.

Are we on the same path and protocol?

Yes, and that is the useful part of the answer. gflow drives the same web app you do, so we see exactly what the browser sees — there is no privileged API we are missing out on.

The difference is between hosts, not between us and the UI. The old labs REST path returns modelNameType per generated image, and dto.py reads it. The migrated batchexecute wire does not appear to carry it for images. We kept the field name when the host changed and quietly started filling it from the request instead. That is the actual defect in #789 — not that we are on a wrong path, but that we inherited a field the new wire does not back.

Worth noting: Flow does store a model per media for video on the labs shape (videoModelControlInput.videoModelName). So the concept exists in their data model. Whether an image equivalent is exposed anywhere on the migrated host is exactly what is unmeasured.

Is it regional?

No evidence for it, and I do not think it is the right shape of explanation. Region and cohort gating are real in this project — the repo already records that a Veo tier may be region-gated — but that changes which models an account is offered, not whether a reply carries an attribution field. And this account is offered Lite: HARBOR_SEAL appears in its catalogue. A missing schema field is not an availability question.

For completeness: this account is served UK-region Google cookies. Testing the same probe from another region would settle it, and I have not done that, so I am not claiming either way.

For your PR

None of this blocks you. It is #789, pre-existing on develop, and it affects every tier equally. It only changes how your live check should be read: it shows the command works end to end, which is real, and it cannot show the tier bound — but neither can mine, so that is not a bar I am holding you to.

Still open from my review: the two blockers, and major 4 (the _IMAGE_REFERENCE_CAP entry filed under a "live-observed" comment).

…erifiable (#790)

* spike(787): Nano Banana 2 Lite is real and usable; its binding is unverifiable

The capability spike the model-governance waiver demanded before this tier ships. PR #787
removes that waiver; this is what it was waiting for.

RUNG 1 CHANGED THE QUESTION, TWICE.

The 2026-08-26 cost/quota catalogue already establishes that image generation costs 0
Flow credits, so "cost" for an image tier means daily quota -- and that "daily quota has
no such oracle. It is observable ONLY on exhaustion, via the 429." So the cost half of
"cost/quality" cannot be answered without deliberately burning an account's day. Recorded
as unanswerable rather than inferred.

It also exposed a sharper question. migrated_composer builds its result with
model_name_type=request.model.value -- it ECHOES our own request. The labs path reads
generated["modelNameType"] from the response; this one does not. And image_records
decodes ids, url, seed, prompt and dimensions with no model field at all. So "it
generated an image with --model nano2-lite" proves the UI did not error, not that the
tier bound.

WHAT WAS MEASURED (4 generations, 0 credits).

The tier is real: HARBOR_SEAL and "Nano Banana 2 Lite" both appear in HTrJv, Flow's own
model catalogue for this account -- corroboration from a surface that is not our request
reflected back.

The quality is fine and is NOT ranked: both arms returned 1024x1024 RGB at 428,799 and
384,036 bytes with no visible degradation, lite slightly more textured. One prompt cannot
rank two tiers and this does not try to. It supports the narrower claim the waiver
needed: lite works and returns a usable image at full resolution.

The binding is UNVERIFIABLE. Both ogiZ0b submit replies were real payloads (~1141 B) and
neither carried any model token. Re-opening the project, HTrJv carries every model token
and no media ids; Zzl0ze carries both media ids and no model tokens. The catalogue lists
models, the media listing lists media, and nothing joins them. So neither #787's live
check nor mine can establish that --model nano2-lite bound rather than silently falling
back. That is the third pre-registered reading, reported as unmeasured.

Surfaced and not about Lite: model_name_type on the migrated path is an unbacked claim on
EVERY migrated image, for every tier. Pre-existing on develop, filed separately.

* spike(789): widen the attribution search — the join is absent from a whole project load

"Unverifiable" was challenged as too strong. Fair, and the boundary has moved.

The first pass searched two replies and FILTERED, recording only ones already containing
a media id or a model token. This pass removes the filter: every batchexecute reply on a
project load, 20-21 of them, all checked.

  HTrJv    24,760 B   all six model tokens   no media ids
  Zzl0ze   41,906 B   no model tokens        both media ids
  tRARke   31,883 B   none                   none
  17 more  139-3,964 B  none                 none

No reply carries both. The join is absent from a whole project load, not merely unread on
the two surfaces first checked.

The page was checked too, because a UI that displays it proves the data is reachable. Two
tier labels exist -- span.settings-summary and span.model-select-trigger-content -- but
the first appears ON LOAD, before any interaction, so both are composer picker state
rather than a property of an image.

ONE READING REMAINS OPEN and would flip this: whether a tier label tracks the media you
open. In one run the label read "Nano Banana 2" on load and "Nano Banana 2 Lite" after a
thumbnail click -- either the settings pane showing current state, or the opened media
loading its own settings into the composer, which would be attribution. The two could not
be separated: thumbnail src does not carry the media id, so a per-media A/B could not be
targeted, and a later run matched zero tiles. Named rather than buried.

Two notes that reframe #789: gflow drives the SAME web app a user drives, so no
privileged surface is being missed -- the difference is between HOSTS, since labs REST
returns modelNameType per image and the migrated wire does not appear to. And Flow does
store a model per media for VIDEO on the labs shape, so the concept exists in their data
model, which is why "find the join" is worth keeping open rather than writing off.

No evidence this is regional: region gating changes which models an account is OFFERED --
and this account is offered Lite -- not whether a reply carries a field. Untested from
another region, so no claim either way.

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.

Gated locally, because CI has never run on this PR

gh pr checks shows green here, and that is misleading: GitHub holds fork workflows, and a run that never started shows as nothing rather than as a failure. Checked directly — for head ec169df4 the only workflow that has ever run is External PR Triage (which is pull_request_target, so forks do trigger it). The CI workflow has no run at all. There is no held run to approve and ci.yml has no workflow_dispatch, so it cannot be dispatched either.

So the head was merged onto current develop locally and put through the full gate:

repo hygiene              ✅  1135 tracked files, no violations
doc links                 ✅  all links resolved across 192 files
website/docs mirror       ✅  in sync (21 files), nav complete
website/docs PII          ✅  no private identifiers
ruff check src tests      ✅
ruff format --check       ✅  480 files already formatted
pyright src               ✅  0 errors, 0 warnings, 0 informations
pytest (offline suite)    ✅  4465 passed, 24 skipped in 391s

The substance of this PR passes everything. This is the first actual verification it has had.

What blocks it: it does not merge cleanly

Three conflicts against current develop — CHANGELOG.md, docs/MCP.md, and website/docs/MCP.md (generated from the second).

CHANGELOG.md is the ordinary kind: keep both entries under ## [Unreleased].

docs/MCP.md needs care, because this branch's line is the older one. The gflow_generate_video bullet here was written against a revision that predates #792, so taking this side wholesale would silently delete develop's run-unique-upload text — the part explaining that hero.png is listed as hero-a1b2c3d4.png so a re-run cannot bind an earlier upload. That loss would not show up as a conflict afterwards; it would just be gone.

The correct resolution is develop's line plus this PR's two additions:

  1. model, duration, count, tools, → model, duration, resolution, count, tools,
  2. after 10 is omni_flash-only), add: , `resolution` ('360p' or '720p', supported on omni_flash)

Then regenerate the mirror with python scripts/ci/generate_website_docs.py rather than editing website/docs/MCP.md by hand.

Once that lands, please push it so a fresh head is created — and note that a fork PR still needs its workflow run approved before CI reports anything.

Taking this over to get it landed. It has been quiet for 12 days, and the feature is worth having. I'll push to this branch (maintainer edits are enabled) and merge develop in rather than force-push, so your commit and authorship stay intact. The plan: resolve the conflicts as described above, drop the cookie-bar accept fallback (blocker 1), log only the reply length and rpcids instead of the body (blocker 2), and start Lite's reference cap at a conservative value marked unmeasured (major 4). The capability spike already settled major 3. If you're still around and would rather finish it yourself, say so and I'll stop.

…er takeover)

- Resolve docs/MCP.md onto develop's line plus the two resolution additions,
  so ffroliva#792's run-unique-upload text survives; regenerate website/docs.
- Blocker 1: drop the cookie-bar accept / first-button fallback; reject only,
  as the COOKIE_BAR_REJECT comment requires.
- Blocker 2: stop logging the ogiZ0b reply body (text_head); length and
  parsed count still diagnose an unparsed reply.
- Major 4: Nano Banana 2 Lite reference cap starts at 3, marked unmeasured.
- New: the labs video driver refuses --resolution pre-submit instead of
  silently billing Flow's default (guard sits after host routing).
- CHANGELOG entry moved under [Unreleased]; --resolution help names the
  failure mode.
- e2e: nano2-lite t2i (client + MCP) and omni_flash --resolution t2v
  (client 720p + MCP 360p) on the migrated host.

Serialize media recovery under the resolved profile lock.

gflow_download_media calls download_media without _profile_lock. download_media opens FlowApiClient, whose ProfileLease fails immediately on same-process contention. A concurrent recovery, generation, or character request can therefore return a ProfileLockedError instead of waiting for the existing browser operation. Resolve the catalog profile first, then hold _profile_lock for the recovery.

Add Nano Banana 2 Lite to the migrated-host image model list.

Line 86 lists only Nano Banana 2 and Nano Banana Pro as supported on migrated flow.google.com accounts. This PR maps nano2-lite to HARBOR_SEAL, and the migrated composer selects it. The new e2e tests cover it on the migrated host. Agents that read this list will assume Lite is unavailable there.

Qualify UUID support by host and mode.

This paragraph says migrated-host frame UUIDs return the exit-36-equivalent error, then says callers can pass frame UUIDs directly and gflow attaches them. The gflow_generate_video documentation in src/gflow_cli/mcp/tools.py:1008-1248 also says migrated-host frame UUIDs are rejected. Qualify the UUID guidance by host and mode to avoid directing users to inputs that the migrated host rejects.

In `@website/docs/MCP.md` at line 87, Clarify the UUID-support statements in the
gflow_generate_video documentation so they distinguish supported hosts and
modes: state that migrated-host frame UUIDs are rejected, and limit direct UUID
attachment guidance to the host and modes that support it. Keep the existing r2v
UUID behavior distinct, and align the statements so they do not imply universal
frame UUID support.

Merged as 3a934175. Thanks @pulsy-cb: --resolution and nano2-lite are both in. Changes made during the takeover: the cookie bar is reject-only again, the ogiZ0b reply body is no longer logged, Lite's reference cap starts at 3 and is marked unmeasured, and the labs editor now refuses --resolution before submit instead of silently using Flow's default. Verified live on a migrated account: nano2-lite t2i through the client and MCP, and omni_flash t2v at 720p (client) and 360p (MCP). All 4 are now e2e tests in tests/e2e/test_migrated_host_e2e.py.
