KCAE.Profiles:3.2 - Storage guarantees belong to their real scope

SQLite’s isolation documentation supports reasoning about committed database transactions and snapshots within its database. It does not transact a separate vector provider or object store. Use it for the atomic catalogue or local state only when the selected mode and operations provide the required behavior.

The OpenAI retrieval documentation describes asynchronous file ingestion and eventually consistent removal. A service using that interface must wait for actual readiness and handle stale removal results. Do not infer complete deletion or cross-store consistency from a successful request submission. This is one provider-specific contract to place inside KCAE.CHANGE, not a universal ban on remote retrieval.

CodeNib v2, especially its boundaries and update experiments, distinguishes a useful multi-view code corpus from a transaction over a mutable workspace. Its incremental/fresh comparisons expose variation and incomplete equivalence despite completed updates. Adopt persistence/reload and changed-case checks; do not claim that its code-corpus results validate a support or method library. The general engineering requirement is to test the source/view relation the receiving use relies on.

A software observer can obtain idempotency support from a runtime library where its persistence and execution assumptions hold. The AWS Powertools idempotency documentation, especially “Concurrent identical in-flight requests” and “Lambda request timeout,” distinguishes in-progress and completed records, rejects concurrent processing and allows another attempt after the in-progress timeout. This is a concrete comparator for KCAE.ENCOUNTER:4.3, not a required SDK. Its stored-result behavior does not settle an external effect performed before completion, or transfer Lambda’s timeout semantics to another worker environment. Obtain those properties from the actual receiver and runtime.
