## 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.

## Current calibration-v2 design intent

Calibration v1 remains a valid frozen compatibility path. It is not weakened or
retroactively reinterpreted.

The current product dependency has changed before the physical campaign because
real A6000 engine-bay acquisition evidence showed that normal operation requires
heterogeneous optics and autofocus. Calibration Science v2 must therefore define
an additive path in which:

```text
one project may mix camera bodies
one project may mix lenses
one project may mix focal configurations
one selected execution may use multiple calibrations
each selected image must resolve to exactly one compatible calibration
autofocus is a normal supported acquisition mode
exposure settings are adaptive rather than fixed scientific constants
```

Capture/quality acceptance and calibration readiness are distinct. A sharp,
usable image with unresolved optics is retained and reported as
`CALIBRATION_REQUIRED`; it is not discarded merely because calibration evidence
is not yet available.

No v2 rule may silently substitute another body, lens, focal state, focus state
or calibration.

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.
