fix(storage): converge the avatars bucket on public read (#316) by AndresL230 · Pull Request #502 · SaplingLearn/Sapling

AndresL230 · 2026-07-31T18:23:34Z

Part of #316.

The issue's suggested fix would have worked, but not lasted

The issue proposes flipping the staging bucket to public. That fixes staging. It does not explain why staging drifted, and it leaves the same drift possible on the next environment.

Both mechanisms that "create" this bucket decline to correct an existing one:

0011_avatars_bucket.sql inserts it with public = true but ends in ON CONFLICT (id) DO NOTHING — a no-op once the row exists.
storage_service.ensure_bucket_exists (called from main.py's lifespan with public=True) treats the Storage API's 409 as success and deliberately does not overwrite settings, "in case an admin has intentionally tuned them in the dashboard".

So a bucket that came into existence private stays private forever, through any number of deploys and migrations. An UPDATE is the only thing that corrects it — hence a new file rather than a re-run of 0011.

The one judgment call

This deliberately overrides ensure_bucket_exists's "an admin may have tuned it" stance, for this bucket only. The read path is an unauthenticated <img src> against /storage/v1/object/public/avatars/..., so private isn't a valid tuning — it's broken avatars. 0029 already recorded the intent ("avatars stays public (intended public read)"); this asserts that state instead of assuming it.

Verification

From-empty replay (scripts/local-db-reset.sh, not a normal cycle — e2e-up runs against a DB that already has the schema): the whole chain applies clean with 0041 in it.
Effect on a drifted bucket: forced avatars to public=false to reproduce the staging condition, then ran the statement — flips to true, idempotent on re-run, and a safe zero-row no-op against a non-existent bucket id.
Full local e2e cycle green (Playwright 37/37, oracles 0 findings).

This does not fix staging by itself

It converges on the next python -m db.migrate against that project. #316 should stay open until that's run — I don't have (and shouldn't use) staging credentials for it.

Staging has avatars public=false while prod is public=true and 0029 records the intent explicitly. Avatar <img> src values are plain public object URLs, so a private bucket serves 400s and every avatar on staging renders broken.

@AndresL230, you've reached your PR review limit, so we couldn't start this review.

Next review available in:19 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

No issues found. Checked for bugs and CLAUDE.md compliance.

Independently verified beyond the diff:

Transactionality/idempotence — db/migrate.py commits the migration SQL and the schema_migrations ledger insert together, so this runs exactly once per environment; the UPDATE is a no-op when already true and a zero-row no-op when the bucket is absent. From-empty replay is safe because 0011 (which INSERTs the row) sorts before 0041.
Privilege claim is real, not assumed — 0029 already performed an UPDATE storage.buckets through this same runner, and the prod snapshots in the working tree confirm those changes are live in prod today.
Security direction — upload_cosmetic_asset writes into the same bucket under cosmetics/, so it's worth stating explicitly: those are admin-managed achievement/role reward assets, not user PII, and docs/security/storage-hardening-plan.md scoped avatars as intended-public while locking down issues-media-files and application_resumes. Prod has had avatars public all along — this converges the drifted staging copy onto already-live, already-reviewed state rather than opening new surface.
Numbering — 0041 is the correct next number; no open PR touches db/migrations/.

Part of #316.

The issue's suggested fix would have worked, but not lasted

The issue proposes flipping the staging bucket to public. That fixes staging. It does not explain why staging drifted, and it leaves the same drift possible on the next environment.

Both mechanisms that "create" this bucket decline to correct an existing one:

0011_avatars_bucket.sql inserts it with public = true but ends in ON CONFLICT (id) DO NOTHING — a no-op once the row exists.
storage_service.ensure_bucket_exists (called from main.py's lifespan with public=True) treats the Storage API's 409 as success and deliberately does not overwrite settings, "in case an admin has intentionally tuned them in the dashboard".

So a bucket that came into existence private stays private forever, through any number of deploys and migrations. An UPDATE is the only thing that corrects it — hence a new file rather than a re-run of 0011.

The one judgment call

This deliberately overrides ensure_bucket_exists's "an admin may have tuned it" stance, for this bucket only. The read path is an unauthenticated <img src> against /storage/v1/object/public/avatars/..., so private isn't a valid tuning — it's broken avatars. 0029 already recorded the intent ("avatars stays public (intended public read)"); this asserts that state instead of assuming it.

Verification

From-empty replay (scripts/local-db-reset.sh, not a normal cycle — e2e-up runs against a DB that already has the schema): the whole chain applies clean with 0041 in it.
Effect on a drifted bucket: forced avatars to public=false to reproduce the staging condition, then ran the statement — flips to true, idempotent on re-run, and a safe zero-row no-op against a non-existent bucket id.
Full local e2e cycle green (Playwright 37/37, oracles 0 findings).

This does not fix staging by itself

It converges on the next python -m db.migrate against that project. #316 should stay open until that's run — I don't have (and shouldn't use) staging credentials for it.

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.
