R/IV CASE 0910 — V14.3 HARDENED MASTER

V14.3 preserves V14.2's two-part accuracy lock and hardens the master in three ways:

1. SOURCE-ADDRESS EVERYTHING
Every flagship WORLD / SCENE / TIME / THEORY / EVIDENCE object has a stable object ID and source-address registry. The UI resolves the object to source, URL, locator, byte/materialization state and SHA-256 when actually available. Missing exact sub-locators remain explicit rather than invented.

2. AUTHORITY-BACKED SCENE GEOMETRY
Plan view uses UVU's official campus building topology as a non-metric transcription. A separate measured cross-section uses only the court-record values of ~415 ft sloped distance and ~68 ft vertical difference. Detailed construction drawings are not claimed because UVU Facilities says they require a formal request. Camera positions/FOV remain schematic unless source-locked.

3. CONTINUOUS ADVERSARIAL REVALIDATION
The package contains a source→visual dependency graph and a runtime function:
  v143RegisterEvidenceChange(sourceId, note)
A source change marks every dependent visual object RECHECK REQUIRED and reruns baseline invariants. The revalidation panel exposes this in the UI.
