fix(extend): handle the Omni extend that grows the source clip in place (#1184) - #1185
Measured 2026-11-08 on a profile served flow.google.com, with the Omni extend key macaron_cookie_extend_4s: the extend returns the source media id, grown in place by about 4 s. Over two paid runs the clip went 7.93 s → 11.83 s → 15.87 s.
A $0 read of the project listing (scripts/dev/spike_extend_1184_listing.py) shows one record for the clip, created 11-07 09:48 and modified 11-08 10:18, the extend's time. No separate extension and no earlier version appear. Positive control: the source id is in the capture.
Changes
Catalog. The extend row reused the source's flow_media_id under a fresh row id, so it failed UNIQUE(profile_name, flow_media_id) (extend_record_failed, DataIntegrityError). Now a started id the catalog already holds is noted on that row: metadata_json.extended_by / extend_unit_cost / extended_at. Its stale duration_seconds is cleared, and status and model are kept. A new id is still inserted as before, so the labs chain is unchanged.
--json.seconds_added, seconds_billed and request.duration come from the key's _<n>s token (4/4 for macaron_cookie_extend_4s). Other keys keep the measured Veo 7/8. Billed seconds are read from the key name, not measured; the only billing fact is 12 credits per run.
Help, dry-run plan, USAGE. They no longer claim the extension alone is downloaded, that each run leaves a new scene, or that it adds a fixed ~7 s. The in-place result is stated as a dated observation, and a Veo key was not observed that day.
Paid e2e. It accepts either contract. For the in-place one, it downloads the source first and asserts the clip grew by the key's seconds.
MCP: video extend is a recorded CLI-only exemption (tests/mcp/test_cli_parity.py), so there is no twin to run. Predict was skipped: no transport, selector, auth or refusal change, and the schema is untouched (metadata keys and a NULL only).
Verification
/gflow:check: every gate green. 6060 passed offline; the 2 failures in test_agent_only_composer_driver.py came from a 15-minute loaded run and pass alone (86/86). This branch does not touch transports.
$0 e2e_auth extend tests: 3 passed on the fix tree.
Paid CLI run on the fix tree (12 credits, 630 → 618): gflow video extend --json exited 0 with seconds_added/seconds_billed = 4 and no extend_record_failed. The file was 15.87 s, up from 11.83 s. The catalog row kept SUCCESSFUL / veo_3_1_lite and gained extended_by.
A fresh reviewer found no blocking defect and three smaller issues: plan text, the e2e's strength, and the stale duration. All three are fixed in the last commit.
Not verified
The last commit came after the paid run. It changes the dry-run text, one SQL column (duration_seconds = NULL, unit-tested on real SQLite) and the e2e itself. The paid e2e in its new form has not run (about 12 credits).
Whether Flow keeps the pre-extend version anywhere was not observed. A page ordering a Veo extend key was not observed that day.
video extend now handles Flow’s in-place extensions, updating the existing clip’s extension details and reporting duration based on the selected model when available.
Default output filenames avoid overwriting clips from earlier runs.
Documentation
Clarified that Flow-hosted extensions save the full clip, while the labs route returns a separate continuation.
Update 2026-11-14: second review round, fixed, and verified on the final tree
Two fresh reviews (code-review xhigh and ponytail-review xhigh) were fixed in one round. Each fix has a test that was seen failing first:
In place is decided by identity (the returned id equals the source's id), not by catalog membership. A recorded id that is not the source still fails loudly.
Nothing is written at submit for an in-place extend. The note (extended_by, extend_workflow_id, extended_at) is written only after Flow reports success. A source the catalog does not hold stays unrecorded, instead of becoming a stuck pending row. extend_unit_cost (always null here) is dropped.
The catalog read in the billed callback can no longer escape and abort a run Flow has already billed.
The _<n>s token is read from keys with a suffix (..._4s_low_priority). --json decides in place by identity and reports null when the length is unknown, instead of Veo's 7/8.
A same-day re-run no longer overwrites the default output file.
Docs (USAGE options table, CONFIGURATION, llms.txt, exit-36 hint, long help) now describe the in-place result.
Merged develop (#1210's @spends_credits markers are the only change to cli_video.py; the plan text was tightened to stay within the size baseline).
E2E on this tree (profile served flow.google.com): tests/e2e/test_video_extend_migrated_e2e.py, 4 passed (three $0 contract tests and the one paid extend), 12 credits.
Paid CLI run (12 credits, 648 → 636): gflow video extend <id> ... --json exited 0, with seconds_added/seconds_billed = 4/4, media_ids equal to the source, and no extend_record_failed. The catalog row kept its status and model, duration_seconds was cleared, and metadata_json = {extended_by: macaron_cookie_extend_4s, extend_workflow_id: ..., extended_at: ...}. The 16.04 s file matches what Flow serves for that id (gflow data download).
Not settled: whether repeated in-place extends add the full ~4 s each time (two extends today ended at 16.04 s). Recorded on #1299 with the follow-ups that were out of scope here.
CodeRabbit was rate-limited on the new commits. Its earlier threads are all answered.
…ce (#1184)
Measured 2026-11-08 with macaron_cookie_extend_4s on flow.google.com: the
extend returns the SOURCE media id, grown by ~4 s (7.93 -> 11.83 -> 15.87 s
over two paid runs); the project listing shows one record, modified at the
extend, and no separate extension or earlier version.
- recorder: a started id the catalog already holds is noted in place
(metadata extended_by / extend_unit_cost / extended_at) instead of failing
UNIQUE(profile_name, flow_media_id); status and model are kept.
- --json: seconds added/billed come from the key's _<n>s token; other keys
keep the measured Veo 7/8.
- help, plan line, USAGE: the in-place result, as a dated observation.
- paid e2e accepts either contract.
- the dry-run plan no longer prints the Veo 1 x ~7s / bills 8s line on
flow.google.com: the length is set by the key Flow picks, stated as the
2026-11-08 observation.
- note_asset_extended clears the stale duration_seconds of a grown clip.
- the paid e2e downloads the source first and asserts it grew by the key's
seconds, reusing _migrated_extend_seconds instead of a copied regex.
The migrated video extend flow now distinguishes in-place results from separate segments. It derives in-place duration values from the extend key, updates the matching catalog asset after successful completion, and saves the returned clip to a collision-safe default path. Tests and documentation describe these behaviors.
In-place results use the duration parsed from the extend key, or null if no duration token is available. Separate-segment results retain the 7-second added and 8-second billed values. The migrated route uses a dated default output path with a random suffix when the base path exists. Help, changelog, and documentation describe the observed Flow behavior.
The CLI passes the source media ID to the recorder. When the result ID matches the source, the recorder skips creating a duplicate asset. After successful completion, the repository updates the matching asset’s extension metadata and clears its stored duration.
Observed behavior and result verification tests/e2e/test_video_extend_migrated_e2e.py, scripts/dev/spike_extend_1184_listing.py, docs/superpowers/spikes/2026-11-08-omni-extend-grows-source-in-place.md
The end-to-end test checks both in-place growth and separate-segment results. The spike report records the observed media and listing evidence. The development script captures and summarizes matching listing payloads.

Merge Risk: Low · previous review f5a65
Successful in-place video extends are now recorded correctly in the normal case. If saving the output file fails after Flow succeeds, the catalog keeps the old duration and gains no extension metadata. The refusal hint may point at the wrong clip when Flow returns a separate segment. Two minor test and dev-script items are open. These are small follow-ups and merging carries low risk.

The title names the main change: a fix to video extend for the Omni extend that grows the source clip in place, which matches the changeset (in-place catalog recording, duration handling via the extend key, the new extend_output_path helper, and documentation updates) and the linked issue #1184. It is specific, single-sentence, and does not use vague terms. The title does not mention the related JSON duration reporting or output-file collision fix, but it does not need to cover every detail.
Full details: Linked Issues check
Explanation
Directly linked issue #1184 has three coding objectives. The whole-PR summary (merge base dce0ad5 to head f5a65d4) shows an implementation for each.
(1) Output and help [#1184]: The extend help, dry-run plan, USAGE, CONFIGURATION, llms.txt and website mirror now state that Flow returns the source media ID and grows the clip in place. They no longer say that the extension clip alone is downloaded or that each run creates a new scene. --out-file saves the returned clip. The second review round also made same-day re-runs avoid overwriting the default file (paths.extend_output_path).
(2) Reported lengths [#1184]: migrated_extend.extend_key_seconds parses the _<n>s token, including keys with suffixes. For macaron_cookie_extend_4s, seconds_added, seconds_billed and request.duration are 4. An in-place result with an unknown length reports null. Separate segments keep the Veo 7/8 values. Unit tests cover the parsing and the in-place decision.
(3) Catalog write [#1184]: When the returned media ID equals the source ID, record_started_extend returns without inserting a row. record_extended_in_place writes extension metadata only after Flow reports success, through AssetsRepo.note_asset_extended. That method keeps status and model and clears duration_seconds. A different returned ID still follows the separate-record path. Recorder tests cover these cases, including the DataIntegrityError collision for a different source.
Verification: PR text reports a paid CLI run (4/4 seconds, source ID, no extend_record_failed) and 4 passing tests in tests/e2e/test_video_extend_migrated_e2e.py on the final tree. This assessment relies on the PR summary and description, because the changed blobs were unavailable in the checkout.
The issue's non-coding evidence step (a $0 listing read) is covered by scripts/dev/spike_extend_1184_listing.py and the spike doc. The unverified points (pre-extend version retention, Veo-key behavior, and whether repeated in-place extends add the full ~4 s) are stated as unsettled in the PR. They are not claimed as implemented behavior, and the PR refers them to #1299.
Full details: Out of Scope Changes check
Explanation
Each changed area connects to #1184 or to supporting work for it.
Product code: src/gflow_cli/cli_video.py (help, plan, JSON durations, in-place recording), src/gflow_cli/data/_recording_video.py and _repo_assets.py (in-place catalog path), src/gflow_cli/api/transports/migrated_extend.py (duration token and refusal remediation text), and src/gflow_cli/paths.py (collision-safe default output name). Each implements an objective or the output behavior that #1184 asks to settle.
Tests: tests/cli/test_cli_video_extend.py, tests/data/test_recorder.py and tests/e2e/test_video_extend_migrated_e2e.py cover these objectives.
Docs: CHANGELOG.md, docs/USAGE.md, website/docs/USAGE.md, docs/CONFIGURATION.md, website/docs/CONFIGURATION.md, llms.txt and the spike doc record the corrected behavior and the dated observation.
Script: scripts/dev/spike_extend_1184_listing.py is read-only. It performs the $0 listing read that #1184 requests.
No transport, selector, auth, refusal policy or schema change appears in the summary. The MCP exemption for video extend is stated and not changed.
Uncertainty: The CHANGELOG summary mentions a root-flag usage-telemetry correction line. No telemetry code file appears in the summary, and the diff could not be read, so this line could not be traced to a change in this PR. It is documentation text only and does not alter behavior. Scope is judged as PASS on the remaining evidence.

Review comments at @scripts/dev/spike_extend_1184_listing.py:
- Around line 40-42: Update records_naming to select and return the enclosing
listing record when a media ID matches inside a nested list, rather than
returning the nested list itself. Preserve the existing ID matching behavior so
the printed summary includes the workflow ID and other record-level fields.
- Around line 91-92: Update the docstring associated with the `records_naming`
hit search to qualify what the positive control establishes: records naming
neither supplied ID are excluded from the printed hits. Direct readers to

Review comments at @src/gflow_cli/cli_video.py:
- Around line 2381-2385: Update the extend command’s `--output` and short help
descriptions to distinguish the observed Omni behavior from labs: Omni outputs
the whole extended clip and adds about four seconds, while labs retains its
existing behavior. Keep the descriptions consistent with the actual output and
duration behavior.
Review comments at @src/gflow_cli/data/repository.py:
- Around line 269-291: Update note_asset_extended to normalize malformed
metadata_json to an object before applying the extension fields, so invalid
stored metadata does not prevent the duration update or recording the latest
extension details.
Review comments at @tests/e2e/test_video_extend_migrated_e2e.py:
- Around line 224-227: Update the source-recovery step in the migrated extend
test so it does not depend on a catalog row: use the supplied project and media
IDs to recover the source, or seed the isolated catalog before calling
download_media. Preserve the per-test catalog isolation and ensure _mp4_seconds
still receives the recovered source bytes.

Declined. The record summary is a convenience print; the spike's conclusion came from enumerating every top-level listing record (created/modified/slot ids), recorded in docs/superpowers/spikes/2026-11-08-omni-extend-grows-source-in-place.md, not from this summary.

@ffroliva Understood. The summary is a convenience, and the spike’s conclusion came from the separate enumeration of top-level listing records. I’ll drop the suggestion.
- paid e2e reads the source through Flow (read_clip), not the per-test
catalog, which is empty, so download_media would raise first.
- --output and short help no longer promise the extension alone or 8 s.
- spike docstring: a version naming neither id is not printed; see the

… success (#1184)
The submit hook now receives the source media id. An extend whose started id
IS the source grows the clip in place: nothing is written at submit, so a
failed or timed-out run leaves the source row as it was and an uncatalogued
source never becomes a pending row for its own id. After Flow reports the clip
done, record_extended_in_place notes it (extended_by, extend_workflow_id,
extended_at; status, model and the clip's own workflow kept). A recorded id
that is NOT the source still inserts and raises DataIntegrityError, which the
caller logs as extend_record_failed. The catalog read in the billed callback
is gone, so a broken catalog can no longer abort a billed run there.
extend_unit_cost is dropped: flow.google.com reports no price.
… null (#1184)
In place is now the returned media id being the source's, not the key's name.
An in-place extend reads its length from the key's _<n>s token, or reports
seconds_added/seconds_billed/request.duration as null when the key has none
(or was not read), instead of the Veo 7/8. A separate segment keeps 7/8.
The review fixes grew cli_video.py past the file-size ratchet (2685). Move the
Omni key-length parser to migrated_extend.extend_key_seconds (beside
submit_facts, which reads the key) and keep the identity decision and the Veo
7/8 constants in _migrated_extend_payload. record_extended_in_place takes its
four values positionally so the call fits on one line.
…1184)
An in-place extend keeps the source id, so <date>/<media_id>_extend.mp4 repeats
for every extend of that clip. paths.extend_output_path keeps the plain name
when it is free and otherwise adds the random tag _unique_display_name gives a
re-uploaded file (#792). It is chosen before submit, never fails after billing,
and leaves an explicit --out-file alone. It checks the local file only, so a
cloud storage_uri key is still reused.
USAGE (--out-file row, the arm's opening line, default file, null lengths, the
catalog note), CONFIGURATION, llms.txt, the exit-36 hint (extend the SAME clip
again) and the --help opening now say that with the Omni key (measured
2026-11-08) Flow grows the source clip in place by ~4s. The CHANGELOG entry
follows the new contract. website/docs regenerated.

scripts/dev/spike_extend_1184_listing.py) shows one record for the clip, created 11-07 09:48 and modified 11-08 10:18, the extend's time. No separate extension and no earlier version appear. Positive control: the source id is in the capture.Changes
flow_media_idunder a fresh row id, so it failedUNIQUE(profile_name, flow_media_id)(extend_record_failed,DataIntegrityError). Now a started id the catalog already holds is noted on that row:metadata_json.extended_by/extend_unit_cost/extended_at. Its staleduration_secondsis cleared, and status and model are kept. A new id is still inserted as before, so the labs chain is unchanged.--json.seconds_added,seconds_billedandrequest.durationcome from the key's_<n>stoken (4/4 formacaron_cookie_extend_4s). Other keys keep the measured Veo 7/8. Billed seconds are read from the key name, not measured; the only billing fact is 12 credits per run.docs/superpowers/spikes/2026-11-08-omni-extend-grows-source-in-place.md. CHANGELOG entry added; website mirror regenerated.MCP:

Summary by CodeRabbit
video extendnow handles Flow’s in-place extensions, updating the existing clip’s extension details and reporting duration based on the selected model when available.Update 2026-11-14: second review round, fixed, and verified on the final tree
Two fresh reviews (code-review xhigh and ponytail-review xhigh) were fixed in one round. Each fix has a test that was seen failing first:
extended_by,extend_workflow_id,extended_at) is written only after Flow reports success. A source the catalog does not hold stays unrecorded, instead of becoming a stuckpendingrow.extend_unit_cost(always null here) is dropped._<n>stoken is read from keys with a suffix (..._4s_low_priority).--jsondecides in place by identity and reportsnullwhen the length is unknown, instead of Veo's 7/8.Merged develop (#1210's
@spends_creditsmarkers are the only change tocli_video.py; the plan text was tightened to stay within the size baseline).E2E on this tree (profile served flow.google.com):
tests/e2e/test_video_extend_migrated_e2e.py, 4 passed (three $0 contract tests and the one paid extend), 12 credits.Paid CLI run (12 credits, 648 → 636):
gflow video extend <id> ... --jsonexited 0, withseconds_added/seconds_billed= 4/4,media_idsequal to the source, and noextend_record_failed. The catalog row kept its status and model,duration_secondswas cleared, andmetadata_json={extended_by: macaron_cookie_extend_4s, extend_workflow_id: ..., extended_at: ...}. The 16.04 s file matches what Flow serves for that id (gflow data download).Not settled: whether repeated in-place extends add the full ~4 s each time (two extends today ended at 16.04 s). Recorded on #1299 with the follow-ups that were out of scope here.
