reviews are clean. Release gate: 6,955 passed / 5 skipped.
- A2 landed in `090b0354`: every production load now captures a specified
immutable origin (including valid map origin `(0,0)`) and carries it through
worker construction, priority/supersession, completion, Far normalization,
and publication. Origin-less or mismatched request-aware work fails before
it can publish. Three corrected-diff reviews are clean. Release gate: 6,965

- [ ] B — capture one immutable world-origin snapshot per load and extract the
serialized DAT-backed `LandblockBuildFactory`.
- Origin capture is complete in A2; B now contains only the DAT-backed
factory extraction and its fixture/serialization gates.
- [ ] C — extract terrain, visibility, EnvCell, building, and render-pinning

- Add owner-call trace tests around the current production order and payload

- Introduce immutable build/publication request/result seams without changing
the live call graph. The typed apply-diagnostics snapshot moves with its
concrete render owner in C instead of creating a temporary A-stage owner.
- Add dependency/reflection guards: no origin-state read from worker, no DAT in
publish/retire interfaces, no residency/generation map in the pipeline.
