From the logic audit (HEAD 04f5f7e):
- P0 CORS: enableCors methods lacked PUT — browsers could not chunk-upload
at all (cross-origin preflight refused)
- P0 chunked: validateUpload enforced the 2 GiB whole-body cap on chunked
completes, so every >2 GiB chunked upload failed after full upload
- P1 presignPut: the SDK's flexible-checksum default added an
x-amz-checksum-crc32 header browsers cannot reproduce; S3Client now uses
requestChecksumCalculation WHEN_REQUIRED
- P1 refresh rotation race: concurrent refreshes both succeeded (consume
ignored rowCount) forking the token family; consume now returns whether
it won and the loser revokes the chain
- P2 logout: awaits the revocation and ignores missing/forged bearers
honestly
page.tsx now calls the real backend: GET /files with groupId/name/mimeClass/
cursor/limit (origin filter dropped — the api has no origin param), shares
tracked as ShareCreated (revoke by id), retention mapped to the orthogonal
legalHold model, downloads by item.name, samples reshaped to the wire
contract.
GroupFile gains mimeClass (the indexed coarse class the row icon and the
filter depend on): core contract, service row mapper, parseGroupFile guard,
test fixture, UI types — one vocabulary end to end. parseGroupFile's roomId
becomes null-tolerant to match direct-upload rows (mapping input stays
strict).
Verified: core build clean, api typecheck 0 errors + group-files 22/22,
web typecheck 0 errors.
Wires the three parallel group-cloud tracks to one surface and fixes the
seams between them:
- chat_media_archive.room_id becomes nullable (direct web uploads have no
Matrix room yet — the contract's null-event pattern extends to the room);
core GroupFile.roomId and ArchiveEntryInput.roomId follow.
- mime_class gains 'archive' (zip) across the 029 CHECK, validation
MIME_CLASSES and the bot classifier — one vocabulary everywhere.
- registerArchiveEntry claim keys are null-safe for room-less uploads.
- New: POST /files/groups/:groupId/upload — FileInterceptor (20 MiB) streams
through magic-byte sniffing, library-safe naming, oCIS upload and the
metadata index, behind group-membership ACL (Owner/Admin bypass).
- safeFileName/sniffMime promoted to packages/core (file-names.ts,
file-mime.ts) so the bot and the api share one implementation; the bot's
local modules become re-export shims; @types/node added to core.
Verified: api typecheck clean, group-files 22/22, bot 74/74, web typecheck
clean; 029 re-applied clean on a fresh scratch DB (room_id nullable,
archive class, claim_key unique all confirmed in the catalog).
