feat: music_generations table and a 100 MiB public-uploads limit - #60
Conversation
Schema for the /music end-to-end slice (recoupable/chat#1992, contract: recoupable/docs#308). Lands before the api PRs that read and write it. music_generations doubles as the run record for the workflow that produces each song, the way playcount_snapshots does: the API reads the row rather than the Workflow API, so one resource answers status, result, and the logs timeline. Ownership is account_id plus a nullable organization_id, both cascading — a generated song is user content, not a log, so it dies with its owner. The bucket limit is a real blocker rather than a nicety: MiniMax returns 44.1 kHz stereo WAV at about 10.6 MB per minute, so the existing 25 MiB cap would fail the upload for anything past roughly 148 seconds while the API accepts up to 300 - after fal had already rendered and charged. RLS is enabled with zero policies. The three most recent tables here skip that statement; these rows hold user prompts, lyrics, and a storage key, so this one does not copy that pattern.

Good catch on the scope of the change, and I lowered the number because of it: 64 MiB rather than 100.
You are right that file_size_limit is per bucket, not per MIME type, so any raise also raises the ceiling for the images, PDFs and CSVs sharing public-uploads. 64 MiB is sized to the longest song the API accepts (300 seconds of 44.1 kHz stereo WAV is about 50.5 MiB) with headroom and no more, which keeps that blast radius as small as the requirement allows.
I did not split out an audio-only bucket. It would scope the limit exactly, but it costs a second bucket, its own key convention and a second upload path, and this PR is being simplified rather than widened. For a 39 MiB difference on a bucket only our API writes to, that trade did not look worth it. Straightforward to revisit if the shared ceiling turns out to matter.

Why do we need BOTH account_id and organization_id?
- I suggest only account_id which can be used on its own to determine if the account is a personal or org account
There was a problem hiding this comment.
Agreed, dropped. Organizations are accounts in this schema, so an org-owned song is just one whose account_id is the organization, and the membership join tables already say which accounts are organizations. Two columns meant two ways to express one fact, and a way for them to disagree.
Knock-on: the client now sends account_id = selectedOrgId in an org context instead of a separate organization_id, which rides the existing override path (validateAccountIdOverride then canAccessAccount) rather than adding a second one.

KISS - can these be removed and queried directly from fal_request_id to prevent excessive (and duplicated from fal) information storage?
- Ideally, this table has the fewwest number of columns possible, but no fewer.
There was a problem hiding this comment.
Dropped all four: requested_duration_seconds, seed, num_inference_steps, guidance_scale.
What made them look necessary was my own design, not the requirement: the workflow read them back out of the row. It does not need to. start(musicGenerationWorkflow, [...]) arguments are durable, so the parameters travel with the run and never need a column. The resolved seed is in fal's result via fal_request_id if we ever want reproducibility, which is Phase 2.
I kept duration_seconds, the actual length, and that is the "no fewer" line for this group: every gallery card renders it, and a list of 20 songs cannot make 20 calls to fal to find out how long they are.

Why is mime type necesary? Is this ever a different value?

Dropped. MiniMax Music 3 returns 44.1 kHz 16-bit stereo WAV, always, so the column held one value forever. The storage key extension carries it if anything needs it.
This also let me delete a speculative mp3-vs-wav branch in the upload step that existed only to populate it.

DRY - Shouldn't this be tracked in the credits_usage or usage_events table?
- Why are we putting credit tracking in the music generation table?
There was a problem hiding this comment.
You are right, and this was the clearest DRY violation in the table. Dropped.
usage_events already records credits_deducted_cents per event with provider and model_id, written atomically with the wallet debit by deduct_credits_with_audit. A second copy here was a second source of truth that could disagree with the ledger.
My stated reason was to freeze the quoted price so the amount charged is provably the amount quoted. That still holds without a column: the cost is computed once at request time and passed to the workflow as an argument, so it cannot drift mid-flight, and the ledger row is the record of what was actually taken.

DRY / KISS - Why are logs being stored directly in the music generation rather that queried directly from the vercel workflow run or kept on the existing runs table?
There was a problem hiding this comment.
Dropped. This was the least defensible column in the table and I should not have added it.
I had argued the row should answer status, result and timeline in one read, with no dependency on Workflow retention. That reasoning does not survive contact with what already exists: this repo reads getRun(runId).status in the chat path, and workflow_runs / workflow_run_steps (20260501000001) is already the place run observability lives. Storing a parallel timeline on a content row duplicated both.
The tell was the cap I wrote into the implementation: a 200-entry limit so a slow poll loop could not grow the row without bound. Needing a cap on a column is a sign it is the wrong home for the data.
workflow_run_id stays as the handle, so the Logs panel can read the run when we want it.
Cost, stated plainly: logs is in the contract that already merged as recoupable/docs#308, so this needs a docs amendment. I would rather pay that now than ship the column.

KISS / DRY - why not query the error on the vercel workflow rather than store it in supabase?
There was a problem hiding this comment.
This is the one I kept, so let me make the case rather than just doing it.
The line I drew is: the timeline is observability and belongs to the workflow, but the failure reason is user-facing content and belongs on the row. Concretely, the gallery lists failed generations and renders the reason on the card, which you approved in the design. Reading it from the workflow means one call per failed row in a list, and a failed row with no reason is a dead end for the user.
There is also a case the workflow cannot cover: if the run itself dies or its record ages out, the row is all that is left, and status = failed with nothing else is indistinguishable from a bug on our side.
It is also not the same string. What goes here is the reason a user can act on, like lyrics tags being rejected, not a stack trace.
Happy to drop it if you would rather the card link out to the run instead, but I did not want to remove it silently on the strength of the logs argument, since the read pattern is different.
Review feedback on KISS and DRY. Everything another system already knows comes out of the table. Dropped: organization_id (organizations are accounts, so account_id alone carries scope), requested_duration_seconds, num_inference_steps, guidance_scale and seed (parameters ride along as workflow arguments; the resolved seed is in fal's result), credits_charged (usage_events is the ledger), mime_type and file_size_bytes (constant, and the storage object knows its own size), source_url (dead the moment the mirror lands), title (nothing ever wrote it), and logs (the workflow run is the timeline; workflow_run_id is the handle). Kept error_message deliberately: the gallery lists failures and cannot make a call per row, and a failed row with no reason is a dead end. Also from review: DROP TRIGGER IF EXISTS before CREATE TRIGGER, which has no IF NOT EXISTS and would fail on a re-run; a positive-duration CHECK; and 64 MiB rather than 100 on the bucket, sized to the longest song we accept, since the limit is per bucket rather than per MIME type.

Simplified: 24 columns → 13Answering the framing question directly — the simplest this table can be, but no simpler — the rule I applied is: if another system already knows it, it is not a column here. What stays is what the gallery has to render without making a call per row. Dropped (11)
Kept (13)
The two I'd flag as judgment calls rather than obvious keeps:
What made the fat look necessaryWorth naming, because it wasn't the requirements: my own workflow design read the parameters back out of the row. Once Also fixed from the bot reviews
Downstream, and not yet doneThis changes the contract, so the cascade is real and I'd rather state it than let it surface at merge:
I'll work through those next unless you'd rather settle Preview branch re-applied cleanly on the new commit (Supabase check above). |
* feat(music): POST /api/music generates songs with MiniMax Music 3 Implements the generate half of recoupable/chat#1992, against the contract in recoupable/docs#308 and the table in recoupable/database#60. The endpoint returns 202 with a pending generation rather than blocking. Every other fal call here is a synchronous fal.subscribe, which works for an image but not for a song that takes one to two minutes, so this uses fal's queue and a Vercel Workflow: submit, poll, mirror the audio into public-uploads, then mark completed. The row is the run record, so the API never asks the Workflow API anything. Credits are gated before fal is called and deducted only after the audio is stored, so a failed generation is free. The price is frozen onto the row at creation, so the amount charged is provably the amount quoted. Also fills a gap the existing content/* fal endpoints have: they charge nothing at all. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017fSvwazBitPfsTQvVqpi8q * refactor(music): follow the 13-column table that shipped database#60 merged at 13 columns rather than 24, so this drops everything the API was writing that no longer exists. types/database.types.ts is synced to the live schema. The Supabase CLI needs an access token this machine does not have, so the column set and nullability were read from the deployed database through PostgREST's own OpenAPI introspection rather than copied from the migration file. Generation parameters and the price now travel as durable start() arguments instead of columns. That was what made them look load-bearing in the first place: the workflow read them back out of the row. Dropped with them: the logs column and its append helper (the workflow run is the timeline), organization_id from the request body (an organization is an account, so account_id carries scope), and the fal-url fallback in audio_url (a row is playable once the mirror lands, which is when it reports completed). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017fSvwazBitPfsTQvVqpi8q * refactor(music): group the workflow and its steps under app/workflows/music The existing workflows sit flat in app/workflows, which was fine at four of them and stops being fine once one feature contributes seven files. Grouping per workflow keeps the music run readable as a unit and makes the next feature's directory the obvious place for its own. Pure move plus import rewrites; no behavior change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017fSvwazBitPfsTQvVqpi8q * fix(music): persist workflow_run_id so a run can be inspected The column existed and nothing ever wrote it, which turned a stuck generation on the preview into an un-diagnosable one: the row said processing, fal said COMPLETED, and there was no handle to read the run's history with. Written from the request path rather than inside the workflow, because the case that needs it most is a run that dies without reaching its own error handler. Best effort: a generation already in flight must not be failed by a bookkeeping write. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017fSvwazBitPfsTQvVqpi8q * fix(music): bound the fal poll loop by attempts, not wall clock Found by preview testing: a generation sat in processing while fal had already returned COMPLETED, and the run kept polling well past the fifteen minute timeout that was supposed to end it. Inside a workflow Date.now() reads a logical clock rather than wall time, so 'Date.now() > deadline' is not guaranteed to become true. The timeout could therefore never fire, and a run that missed completion polled forever with no way to end itself. Counting attempts is the only bound that does not depend on how the runtime advances time. sleep() also now takes the interval as a duration string instead of a Date computed from that same clock. This does not by itself explain why the loop missed a COMPLETED status that the same client call returns correctly outside the workflow; that is still being chased. It does mean the next stuck run ends itself instead of running until someone notices. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017fSvwazBitPfsTQvVqpi8q * fix(music): sleep with a Date, the form that actually resumes The run trace settled it. With sleep("10s") the span records a completed 9.97s sleep and then the run sits active for nine minutes with no further step: the resume never fires. With sleep(new Date(...)) the same loop resumed every cycle, which is also the form sandboxLifecycleWorkflow has been using in production. Both forms are documented, so this is empirical rather than a reading of the docs. Keeping the counted attempt bound from the previous commit, since that is what guarantees termination regardless of how the runtime advances its clock.

It is both the generated-song record and the run record for the workflow that produces it, mirroring howplaycount_snapshots(20260610010000) works: the API reads the row, never the Workflow API.

MiniMax Music 3 returns 44.1 kHz 16-bit stereo WAV, roughly 10.6 MB per minute. Against the 25 MiB limit set in
20260508151035, a mirrored song is capped at about 148 seconds — while the documented API accepts a requested duration of up to 300. Without this, a long generation renders successfully on fal, gets charged, and then fails at the upload step, which is the worst place to discover a limit. 100 MiB covers a 300-second WAV (about 53 MB) with headroom.allowed_mime_typesis untouched:audio/wavandaudio/mpegwere permitted from the start.Decisions worth a look
Real cascading FKs, not loose ids.
