A logged-in user could file submissions without bound and stream a 1 GiB
context per submission. The only limits were the single-blob size cap and the
5 GiB uploads PVC (platform/workloads.go); nothing counted a user's rows or
bytes, so one account could fill the volume and every other user's upload
would start failing.
- Create: per-user pending_review cap (default 5) — the review queue cannot
be parked full of one account's rows. Check-then-insert, documented soft.
- UploadContext: per-user stored-context budget (default 2 GiB) charged
against the blob store's REAL sizes (new Blobs.Size on local/S3 stores), so
the sum cannot drift from the volume; the write is capped at the remaining
budget, so the excess is refused before it is persisted, and a re-upload is
charged only for its new bytes.
- API: per-user create/upload throttles (30s/15s, cmd/felis-wired) on a
dedicated cooldown keyspace, reserve→release so a failed attempt never
burns the window and a burst collapses to one winner; ErrQuotaExceeded →
403 submission_quota_exceeded (distinct from the 400 an oversize blob
gets), 429 submission_cooldown for the throttles.
- Panel: zh/en copy for both codes; openapi documents 403/429 on the two
user routes; pgint covers the pending-queue count.
Unit tests: submit package (cap, budget boundary/exact-fit/replacement,
oversize-vs-quota split) and api handlers (quota 403 both paths, throttle
429 + recovery + failure-release). go vet/go test/gofmt clean; panel
vitest 118 + typecheck green.
