- New ADR-0006 documenting the OS keychain migration: context,
options considered (keyring vs stronghold vs AES-from-PIN), the
backend choice rationale (sync-secret-service vs async-secret-
service), anti-downgrade design, migration semantics, and the
subscription-tampering fix via account_cache.
- architecture.md updated: new token_store / account_cache module
entries, auth_commands descriptions now point at the keychain-
backed API, OAuth2 + deep-link flow diagram mentions the HMAC
step, command count bumped to 35.
- CHANGELOG.md + CHANGELOG.fr.md under Unreleased:
- Changed: tokens moved to keychain with transparent migration
and Settings banner on fallback.
- Changed: account cache is now HMAC-signed.
- Security: CWE-312 and CWE-345 explicitly closed.
Manual test matrix (pop-os + Windows) is tracked in issue #82 and
will be run by the release gatekeeper before the next tag.
