It answers one narrower question: +can an immutable semantic mask be bound to the exact RAVNOVES00 camera frame, +projected through the admitted factory KB4 calibration onto the complete +frame-local SLAM/LiDAR point index space, and aggregated for observations which +already exist in the M4 geometry ledger? + +The seam is deliberately model-neutral: + +- a provider supplies a source/frame/model/preprocess-bound `uint8` class-ID mask; +- the admitted KB4 projection assigns a semantic status to each source point; +- the four statuses remain distinct: `labeled`, `ambiguous`, `unprojected` and + `absent`; +- observation semantics are detached diagnostics over immutable observation and + source-point IDs; +- semantic absence never means free and semantic output cannot create an + obstacle or change identity, metric geometry, occupancy, motion or threat; +- navigation, safety, command, physical-live and actuation authority remain + false. + +The full-route E4 EoMT result is the fixed control provider because its 4,489 +masks, model revision, weights digest and input identity already exist as sealed +evidence. This does not promote EoMT to the production model. A later NVIDIA +CitySemSegFormer or other candidate must enter through the same provider seam and +be compared on frozen independent truth. `supervision` may be used as rendering +or evaluation tooling, but it is not itself a segmentation model. + +The temporal claim is intentionally narrower than physical synchronization. +All `4,489` E4 mask rows and the sealed E10 source-pack entries have identical +camera ordinals and identical recorded `session_seconds` (zero difference after +conversion to nanoseconds), so E47 now verifies that binding fail-closed for +every frame. The LiDAR and pose entries inside E10 still inherit the admitted E6 +`nearest-host-arrival-best-effort` binding. Their recorded per-frame deltas are +checked against the existing `100 ms` limits, but this does not prove a shared +hardware clock or zero camera-to-LiDAR skew. E47 therefore remains warning-grade +diagnostic evidence and cannot be described as physically synchronized. + +The reusable UI reads the same recorded clock in `VIDEO`, `CAMERA`, `3D` and +`PLAN`: the mask is drawn below existing boxes and the matching semantic class +IDs color only the exact current point increment. Any unknown mask class, +point-index mismatch or artifact-accounting drift is an explicit integrity +failure rather than an empty or cosmetically clean layer. + ## Target reference graph ```text
