Tyler J King	e744336385	fix: capability enforcement, credential safety, atomic delegations, input validation ... C-6: ConnectorRuntime enforces capability_mask per operation. READ-only ACs cannot invoke MUTATE operations (wipe, lock, retire). C-7: AC validated against database (exists, active, not expired) before connector invocation. C-9: Delegated AC capability bounded by delegator's capability. C-10: Command counter uses atomic SQL increment with limit check. M-23: expire_stale() uses same atomic SQL pattern. H-1: Sensitive credential fields hidden from repr/logs via repr=False. H-2: Stub backend requires ALLOW_STUB_CREDENTIALS=true to activate. H-3: Kerberos backend raises CredentialResolutionError instead of returning stub ticket. H-4: Chronicle INTENT emitted before execution, RESULT after. H-5: device_id validated as UUID before Graph API URL interpolation. H-8: ConnectorRuntime enforces governance for all connector invocations.

Tyler J King	24eefe1699	feat(credentials): add Entra and Stub credential backends ... Entra backend resolves OAuth tokens via MSAL client_credentials (OBO flow wired in future sprint) and passes ACs through for Bascule. Kerberos stubbed pending hybrid environment config. Stub backend for dev/testing without real IdP. Signed-off-by: Tyler King <tking@guildhouse.dev>	2026-04-14 05:57:52 -04:00
