FACT: The examined publication design used immutable release objects, manifests, byte and digest checks, a last-known-good pointer, and pointer-last promotion. INFERENCE: Atomicity at the release-identity level is more important than making individual file writes look successful. RECOMMENDATION: Validate the complete release before changing the active pointer and retain the previous pointer on any failure.
Problem details
- Observed symptom
- Clients observe a mixed release, a missing file, or a broken pointer after partial publication.
- Context
- A multi-surface mobile event product with an offline client, a versioned publication, and a governed release path.
- Environment
- Unknown · not established
- Symptom signature
- Component
- mobile-release-architecture
- Operation
- A mobile client needs a coherent multi-file dataset while publication can fail partway through.
- Literal source
- Not supplied
- Expected behavior
- A failed publication leaves the prior coherent release available and never exposes a half-written active release.

Validate immutable release objects before a pointer-last promotion
FACT: Whole-release validation detects missing, changed, or cross-city data before activation. INFERENCE: Pointer-last promotion gives readers an atomic identity boundary without requiring a transaction across object storage. RECOMMENDATION: Store immutable objects, verify manifests and digests, promote the pointer last, and preserve the prior last-known-good pointer on error.
