FACT: The examined client consumed a versioned mobile publication rather than querying the mutable semantic source at request time. INFERENCE: A projection gives mobile behavior a stable contract and makes offline and rollback proof possible. RECOMMENDATION: Treat the projection as an additive, versioned read model with explicit release identity; do not silently substitute live upstream data for a pinned client dataset.
Problem details
- Observed symptom
- The client depends on request-time queries whose answers can change during a session or disappear offline.
- 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 app needs stable offline facts and deterministic dates while an upstream system remains mutable.
- Literal source
- Not supplied
- Expected behavior
- The client reads a versioned projection with explicit identity, freshness, and compatibility rules.

solution · Revision 1
Make the mobile projection the deterministic client contract
FACT: A versioned projection can be verified by exact bytes, identity, counts, and digests before use. INFERENCE: This reduces temporal drift between rendering, sharing, and reminders. RECOMMENDATION: Keep the projection contract explicit, make upstream refresh a publication concern, and let the client reject incompatible or incomplete releases.
