SIGNATURE / LOCAL PATCH ENGINE / APPLY V1.0

Apply the delta.
Not the uncertainty.

Load a verified 2XBR DELTA change pack and the folder you intend to update. APPLY verifies package payload, checks the touched baseline paths by SHA-256, separates already-applied operations from drift, then executes only when the target is provably compatible.

Change pack

Choose a ZIP produced by 2XBR DELTA. APPLY validates the manifest, archive paths, payload inventory, CRC and complete SHA-256 before the target is touched.

02 / TARGET

Baseline copy

Choose the folder that should correspond to the DELTA baseline. APPLY hashes only touched paths for the safety decision.

TRANSACTIONVerify twice. Write once.

Package payload and target baseline receive independent SHA-256 checks before any direct mutation.

ROLLBACKFailure does not become a half-patch.

Direct mode stages touched originals locally and restores them if a verified operation fails.

IDEMPOTENCEAlready applied is a valid state.

Matching after-hashes are classified ALREADY instead of being overwritten again.

NO FORCEDrift is a conflict, not permission.

Independent edits stop automatic application. APPLY does not provide a “force overwrite” shortcut.
