I read this as an adversarial verification of Todo 4 r2 only - I will inspect the prescribed evidence and implementation, run non-mutating checks/repros, then append the requested verification record and cleanup receipt only.


I read the current r2 as having its advertised source hashes and clean direct diagnostics, but I found the recorded profile virtualenv is a persistent executor-era mutation; I am now reproducing the remaining authority-boundary and restart cases against disposable real trees.


I read this as adversarial verification of Todo 4 r2 - I completed the audit and recorded a non-confirmation.

**AdversarialVerify: not_confirmed**

Blockers reproduced on real disposable canonical/sidecar trees:
- Root replacement after restart appended `source_advanced` instead of typed-failing.
- Canonical transaction `lock_path` substitution appended `submitted`.
- Same-UID swap-and-restore of canonical files committed a rogue source digest.
- Executor retained ignored `dualcoach/profile/.venv` with pytest 9.1.1 installed at 20:56; cleanup/provenance is not truthful or zero-residue.

Verified: 33 Todo4, 142 Todo3, and 124 canonical/reporting tests succeeded; ruff, ty, basedpyright, direct LSP, compileall, no-excuse, LOC checks were clean.

Evidence:
- `task-4-correlation-independent-verification-r2.json`
- `task-4-correlation-independent-verification-r2-cleanup.json`
