 ## 1. Contract Freeze
 
-- [ ] 1.1 Add Protocol `DisplayMode`, negotiated display fields/features, VGI1 absolute/scroll grammar, strict valid/invalid cross-language fixtures, and optional-field omission regressions
-- [ ] 1.2 Regenerate Go/Rust/Swift outputs twice, pass Protocol `make verify`, freeze a verified-unused immutable Phase 3D RC, and record its fixture/generated hashes
-- [ ] 1.3 Update Server and Data Plane to the exact Protocol RC without a filesystem replacement and prove clean-cache module resolution before consumer implementation

 ## 2. Server Display Authority
 
-- [ ] 2.1 Add the forward-only nullable requested/effective display and policy-version migration plus clean-install/upgrade/schema/grant tests
-- [ ] 2.2 Add strict request validation and requested-mode idempotency identity, including waiting-session mismatch regressions
-- [ ] 2.3 Implement one proportional even-pixel/FPS clamp at allocation and atomically persist the immutable requested/effective decision
-- [ ] 2.4 Disclose display-aware broker/manifest values only to negotiated clients, preserve legacy response shapes, and reuse the persisted mode on reconnect
-- [ ] 2.5 Project persisted effective width/height/FPS through existing provider work with selected immutable codec/bitrate/audio and pass focused repository/E2E tests

 ## 3. Gateway Input Translation
 
-- [ ] 3.1 Add red VGI absolute/scroll encode/decode/bounds/fuzz/transport tests and prove unadvertised kinds fail before provider translation
-- [ ] 3.2 Establish exact Apollo absolute-pointer and scroll vectors from the approved pinned source; hard-stop without that evidence
-- [ ] 3.3 Implement the smallest provider-neutral VGI validation and Apollo adapter translation without adding pressed-state or direct-provider surfaces
