Please review the entire current implementation, not only the latest WSL drain patch.

For the previously reported post-exit WSL drain finding, evaluate the current Return material findings only (P0/P1/P2 or equivalent).

1. rm -rf lacks ownership checks 📘 Rule violation ⛨ Security
The workflow cleanup recursively deletes $CARGO_TARGET_DIR without an explicit ownership/canonical-path check that it is within the intended temporary directory. A mis-set variable or unexpected path resolution could delete unintended directories.
Agent Prompt
## Issue description
The release-candidate workflow uses `rm -rf` for cleanup without verifying the deletion target is a canonical descendant of the temp workspace directory.
## Issue Context
Compliance requires explicit ownership/scope checks before recursive deletion, even in CI scripts, to reduce risk from unexpected variable/path values.

2. Replacement file can be deleted 🐞 Bug ⛨ Security
Unix history pruning checks a retained file with fstatat and then separately deletes its name with unlinkat, so a concurrent rename-and-replace between those calls causes the replacement file to be deleted. This breaks the new object-bound cleanup guarantee and can remove foreign data placed in the owned session directory.
Agent Prompt
## Issue description
Unix history pruning validates each file identity and then unlinks the pathname in a separate operation. A concurrent rename-and-replace can therefore make the unlink delete an object that was never validated.
## Issue Context
The same check-then-unlink pattern is also used for the final session directory. Preserve fail-closed behavior and ensure destructive operations cannot resolve a different filesystem object after identity validation.

DRAFT / T068 REPAIR IN PROGRESS — DO NOT MERGE
This branch repairs material findings from the independent full-implementation review in PR #62. It is intentionally opened early to obtain compile/Clippy/test feedback while reconciliation is still in progress.
Current repaired surfaces include:
Known T068 findings remain under reconciliation; this PR is not yet a final implementation candidate and no independent-review pass on this head should be counted yet.
Hard boundaries:
8601b7db...failed T068 independent review.Summary by cubic
Closes key T068 independent‑review findings across Git/WSL discovery, terminal lifecycle, cloning, Store/history, CLI identity, and CI provenance. Old behavior allowed unbounded subprocess I/O/lifetimes, partial clone artifacts, non‑monotonic Git facts, weak Store/CI invariants, and ambiguous cleanup; new behavior bounds probes in owned process scopes, publishes clones atomically, enforces typed BEFORE/AFTER Git observations with monotonic times, restores safe object‑scoped history pruning, requires complete workspace Git identity, and binds CI to the exact candidate head.
Git/process scope: run read‑only Git in owned
process_scopewith output/time limits and verified stream closure; separate dirty presence from bounded evidence; enforce AFTER ≥ BEFORE and record monotonic times.WSL: bound discovery/attestation in owned scopes with deadlines; prove scope cleanup via tokens; CI proof waits for stdout/stderr closure.
Cloning: stage in uniquely owned paths with pinned identity; publish atomically without replacement; failed clones leave no destination; cleanup/retries fail‑closed.
Terminal: preserve canonical Windows drive CWD at spawn; bound termination and persist cleanup truth; prove ConPTY markers originate from shell output; make deferred finalization retries resilient.
Store/history: reject empty exit observations; finalization requires a durable observed‑exit fact; floor ownership‑loss at observed start; restore object‑scoped pruning with normalized path identity; history‑root init is race‑safe; add T068 regression tests.
CLI/snapshots: require that the worktree root and Git common directory match the workspace; snapshots expose persisted typed Git BEFORE/AFTER observations with monotonic times.
CI/provenance: workflows derive
