Replaces the multipart-via-API path for image uploads with a three-step
direct-to-storage flow:
1. Client POSTs /api/uploads/presign with content_length + content_type;
server validates size (10 MB cap), mime allow-list per category, rate
limit (50/hour/user via Redis sliding window), and concurrent unclaimed
cap (10 in-flight per user). On success it persists a pending_uploads
row, signs an S3 POST policy with content-length-range bound to the
claimed length ±256 bytes, and returns the URL+fields.
2. Client POSTs the bytes directly to B2 using the signed policy. B2
enforces size, content-type, and key match before accepting.
3. Client passes upload_ids[] to /api/task-completions/ or /api/documents/.
Service HEADs each B2 object, verifies size matches expected_bytes
within slack, marks pending_uploads claimed_at, and creates the
associated TaskCompletionImage / DocumentImage rows.
Bytes never traverse our API server. The 1 MB Echo BodyLimit middleware
that was rejecting all task-completion image uploads becomes irrelevant
for this path. Existing multipart endpoints stay functional alongside,
soak-testing the new path before legacy removal.
Cleanup:
- cmd/worker registers a new hourly cron (TypeUploadCleanup, "30 * * * *")
that reaps pending_uploads where claimed_at IS NULL AND expires_at < NOW().
Reaps both the B2 object and the row.
- B2 bucket lifecycle rule on `uploads/` prefix (7 days hide → 1 day delete)
documented in deploy-k3s/manifests/b2-lifecycle.md as a backstop.
Schema:
- migrations/000002_pending_uploads.sql adds the table + partial index for
cleanup + nullable pending_upload_id FKs on task_taskcompletionimage and
task_documentimage.
Policy (single tier, no free/pro split):
- 10 MB cap per upload
- 50 presigns/hour/user
- 10 concurrent unclaimed uploads/user
- allow-list: jpeg/png/heic/heif/webp for image categories;
+ pdf for document_file
