1.0.1

1.0.1 — 2026-07-16

• Fix: installer no longer reports failure to CI-style hosts after a successful self-check
  (leaked exit code from the known-bad fixture probe).
• Fix: the validator resolves its default schema directory from versions.json instead of a
  hardcoded version, so schema-version bumps apply everywhere.
• Tests: added the missing invalid viewers fixture (36 tests).
