Conversation
- Validate complete catalog exports before publication - Preserve generation provenance and advance R2 indexes conditionally - Bind serialized uploads to current main and separate staging credentials
- Match cache bodies, validators, and refresh timers to URL and client version - Validate downloads and preserve matching caches on failure - Use the Diffex catalog origin and retire catalog identity exceptions
- Exercise real publication, Worker serving, CLI refresh, and offline recovery with isolated fixtures. - Detect missed generation and production publication independently of content age. - Bind generation and upload to the resolved source revision.

- Emit the publication decision on stdout so the script cannot write an environment-selected file. - Restrict fixture property writes to known providers and cover the CLI regression.

Summary
Move model-catalog publication and refresh to the Diffex-owned API at
https://api.diffex.ai/api/models/providers/{providerId}.Existing caches from another URL or client version fall back to bundled models until a valid refresh succeeds.
Reasoning
Create-only revision objects, verified immutable manifests, and conditional index writes prevent interrupted or concurrent publication from exposing incomplete catalogs.
Cache provenance prevents old endpoint data, validators, or refresh timers from suppressing the migration.
Compatibility floors retain supported clients while immutable timestamps keep revalidation stable when content is unchanged.
Changes
0.3.3.Testing
npm run checkpassed on current main plus this branch../test.sh otherpassed after compiling the telemetry prerequisite in the fresh worktree.
