Kosmos Extensions

This repository is a frozen, compatibility-only catalog for legacy .kext clients. It is not the source of truth for current product discovery or installation.

Legacy entries in catalog.json carry explicit deprecation and replacementId metadata. The exact migration contract is versioned in catalog.json and explained in docs/migration-contract.md:

• Arrancador and the legacy Arcadia entry migrate to com.kosmos.arcadia;
• Eden migrates to com.kosmos.memoria;
• Delphi migrates to com.kosmos.agenda.

A compatibility client may resolve these aliases for upgrade, but no entry in this feed is an active current product. New first-party discovery belongs in the signed Store catalog, and installation authority belongs in the signed Package Index. Do not publish new first-party artifacts here.

Validation

Catalog CI rejects duplicate identities, malformed metadata, non-HTTPS or invalid artifact integrity values, missing deprecation reasons/replacements, and replacement cycles:

node scripts/validate-catalog.mjs
node --test scripts/validate-catalog.test.mjs

The frozen client window, cutover checklist, and archive policy are in docs/compatibility-cutover.md. The final migration of existing .kext data, settings, and grants remains a consumer/client release gate; this repository cannot prove that external upgrade path by itself.

Local hooks

Install Lefthook for automatic pre-commit and pre-push checks, or run the two Node commands above directly. The checked-in lefthook.yml contains no secrets and only validates this compatibility feed.
