+Independent preparation for T04 while T02 remains blocked. Add a disposable
+fixture that delegates actual dispatch to the catalog-built ReinAharness,
+validates the commit and artifact through owner execution before teardown,
+checks the host source and cleanup, and emits bounded evidence without model
+output or credential values. Refuse blocked or unpinned profiles before
+creating a sandbox. Test negative artifact cases and the refusal path. This
+runner does not itself satisfy T04 or change readiness.
+
+Completed 2026-09-05. `scripts/prove-local-profile.py` delegates real dispatch
+and observes content/commit acceptance before teardown. It verifies exactly one
+new commit, expected paths and committed/worktree content, a clean tree,
+source absence, exact child identity, private task mode/removal, and host-source
+integrity plus workspace destruction. It emits bounded evidence and has no
+readiness override. `tests/test_local_profile_proof.py`: 20 focused tests pass;
+full suite: 101 passed; catalog validation passes. A real CLI invocation against
+`harness.agent-dev-local@1.0.0` returned `OperationallyBlockedProfileError`
+without creating a sandbox. T02–T05 remain waiting on the owner dependencies;
+no real model run or readiness promotion is claimed.

 ## Acceptance
 
 One version-pinned local profile runs its actual rein/model task entirely in
