Overview

Resolves the live value for a registered integration setting key.

Precedence: DB > ENV > registered default.

  • DB value wins as long as an ::Collavre::IntegrationSetting row exists with a non-blank value (encrypted at rest via ::Collavre::IntegrationSetting).
  • ENV is consulted only when no DB row exists.
  • The registry's static default is the final fallback.

Caching:

  • Sensitive definitions are NEVER cached. Rails.cache may resolve to a durable store (e.g. :solid_cache_store in production), which would persist decrypted secrets outside the encrypted value column and defeat at-rest encryption. Sensitive reads hit the DB every time.
  • Non-sensitive definitions are memoized in Rails.cache for 5 minutes under ::Collavre::IntegrationSetting.cache_key_for(key). The model's after_commit hook invalidates this key on any write.
