M11-06 Status

status: done task: server render job provenance binding updated: 2026-08-17 America/New_York

Scope

web/protocol/server-render-job.ts defines schema 1 for a server render request and result. A request is accepted only when the uploaded .blend bytes match its declared source SHA-256 and byte length, the Blender build is a declared 5.2 build with a content hash, and canonical bounded render settings match settingsSha256. The request itself is bound by requestSha256.

A successful result carries the same source/revision/build/settings identity and adds output MIME, byte length, and output SHA-256, plus resultSha256. Consumers recalculate the output hash before accepting pixels. The contract does not claim a remote queue, progress, cancellation, denoise, or Freestyle implementation; those remain later M11 tasks.

Evidence

• npm --prefix web run test:server-render-job: unit 3/3 and a real loopback server check passed.
• The check used Blender 5.2.0 headless to open tests/files/web/m11_render_reference.blend and render a PNG from the submitted source bytes. It verified source/build/settings/output hashes and rejected source, build, settings, and output tampering.
• Result: server-render-job-ok blender=5.2.0 source=d2bea55fe4de0b00e73a9241b4d1b0c802c2eb0e6159c0cd48e007b97b9d3963 settings=97bb832618bd27e8763722afa0d250ef74383fb355f0ff38763930f57ba1590b output=564b95cd501da2636085aeada88814c4a3b7af7b1f0188543a1863fe34dd091e bytes=3915 source-hash=1 build-hash=1 settings-hash=1 output-hash=1 tamper=4.
• Full regression passed: typecheck, lint, Node 168/168, status consistency (12 parity blocked, 0 release blocked), release evidence (17 records, 0 missing), production build (75 modules), and git diff --check.

Rollback

Remove the server-render-job protocol, error codes, unit/check commands, and this status record; restore M11 to 5/14 and remove the M11-06 completed slice. Keep M11-05 routing, M11-04 reference metrics, and all earlier lighting/resource behavior unchanged.
