## FROZEN

Preserve at their documented boundaries:

- Capture / Asset Provenance;
- acquisition ingestion and durable campaign execution;
- Photo Quality Triage;
- Selected Scientific Execution;
- Geometric Verifier v3;
- Track Model / Track Builder;
- Sparse SfM capability through Gate G (detailed lifecycle: Gate A decision/historical; Gates B-G PASS/FROZEN);
- Phase H v1;
- MVS-M1 external OpenMVS 2.4.0 boundary;
- Calibration Science v1;
- Calibration Tooling v1;
- Calibration Bootstrap v1;
- Internal Parallelism / Compute Resources;
- Resource / Compute Governor;
- ORB Vulkan backend;
- Global Maintenance Audit;
- Real S21 Tracks;
- Real A6000 pre-SfM.

`FROZEN` protects meaning and boundary, not necessarily every file byte.

The project-directory name is historical and must not be mistaken for schema head.

## Canonical-reference rule

When implementation enters this area, read the cited canonical document in full before editing. If this prompt summary and the canonical document appear to conflict, do not silently choose the shorter text: determine whether this file is stale or whether a real contract contradiction exists, then apply the STOP rules where necessary.
