For scale: payload bytes go browser → R2 → browser; the api handles keys,
authz and metadata only, so a cheap box can serve thousands of users.
- SPENC2 frame (browser-sealed, P-256 ECDH → HKDF wrap of a per-file CEK,
10 MiG AES-GCM segments): storage.ts gains the reader (magic-branched
getObject), presignPut/headObject, openDirectHeader; sealForDirect is the
reference sealer for cross-implementation tests
- Files API: GET /files/direct/config, POST /files/direct/init (presigned
PUT), POST /files/direct/complete (HEAD-gated commit), POST
/files/:id/direct-download (presigned GET + CEK ticket)
- web: lib/direct-storage (WebCrypto seal/open), lib/files-direct (flows),
dropzone rewritten with a multi-file sequential queue (per-file status,
direct-first with server fallback), file download decrypts in-browser for
direct objects (falls back to streaming)
- video dropzone wired to the chunked ingest API (>10 MiB → init/chunk/
complete), fixing the Cloudflare ~100 MB body cap for large videos
- DIRECT_EC_PRIVATE_KEY (P-256, PKCS8 b64) wired through compose; cross-impl
roundtrip tests prove web-seal ↔ server-open byte compatibility
