Durable instructions method

Load project-protocol:project-protocol for run records and gates. Receive project root, worktree/snapshot, scope, requested instruction destinations, mode, existing files, evidence paths and authorizations. Reuse the caller's run.

Destination and authority

Read references/instruction-loading.md during preparation. Bind the actual host/version, configured discovery and applicable root/nested scopes; a file's presence does not prove it is loaded or enforceable. Record evidence and unknowns in the owned run rather than assuming every host reads the same files.
