## Scope

Six theory pages and one tests matrix in both languages, 45 new equation IDs, four bilingual open tasks and two preserved legacy entrances.

## Scientific boundaries

The Chapter 2 exterior construction is canonical source content, not independent experimental proof. Its static action and optical path match Schwarzschild expressions; second order and static shadows are not presumed discriminators. Eq. (2.42) is first-order precession. Continuum termination is a hypothesis.

## Sources and deferred material

FND-3dde8d8e081d is reused, with Chapter 2 SHA f9598318d123c1f85a7d720af9cecbed8392e0b399910e3f9bfb675d49494709. Boundary thermodynamics, full rotation and S301 data fitting are not expanded this cycle. The Chinese final manuscript is authoritative.

## Release

The source version and bilingual content are synchronized. The GitHub/Cloudflare update package preserves the existing deployment configuration.
