Fsync the keyring directory after both complete temporary files are written and synced, before replacing the primary document. Pre-publication directory failures now preserve the prior primary state and remain rollback-safe.
Keep the durable recovery temporary file available when later directory or backup publication work fails, and verify that it restores the committed keyring.
Rank equal-time recovery candidates deterministically with recovery temps before primary temps and backups, and consider equal-time commit temps alongside a valid primary.
Recover from structurally valid but undecryptable primary keyrings by selecting a fully cryptographically validated backup or recovery temp and reporting KEYRING_RECOVERED.
Keep committed primary writes successful when best-effort post-publication cleanup fails, preventing ambiguous retries after durable local publication.
Intercept clipboard writes inside the hidden Electron Main-process integration probe, remove the duplicate key-created toast, and make authoritative refresh coverage differ from optimistic state.
Require canonical encrypted envelopes and surface typed sanitized keyring corruption states.
Persist crash-durable primary and recovery files, prevalidate removal plans, isolate renderer refresh authority, and cover the real hidden Windows DPAPI and IPC composition.
