Step 16b: Outside-In Testing Results

Detected toolchain: Rust (single crate simard, edition 2024, Cargo.toml/Cargo.lock at root, cargo 1.95.0). Per the qa-team skill's repo-type detection, Rust CLI repos substitute cargo test for the gadugi-agentic-test harness; no gadugi framework required.

Chosen strategy: Exercise the changed outside-in boundary — the self-deploy unit-test canary gate in src/self_relaunch/gates.rs — via native Rust tests. Two scenarios: (1) a simple run of the new hermetic-isolation convergence tests, and (2) an edge/integration run of the whole gate suite under the hostile ambient environment that originally triggered the exit-101 crash-loop (SIMARD_STATE_ROOT pointed at a busy "live" root, exactly as the running daemon sets it).

Scenario	Command	Result	Key output
Simple — hermetic gate convergence tests	cargo test --lib self_relaunch::gates::convergence_tests	✅ PASS	test result: ok. 9 passed; 0 failed (includes unit_test_gate_overrides_allowlisted_live_state_root_with_isolated_root, isolated_state_root_wins_over_reinjected_allowlist_by_ordering, isolated_state_root_is_private_0700_and_removed_on_drop)
Edge/integration — full gate suite under hostile ambient SIMARD_STATE_ROOT (reproduces the #4522 exit-101 condition)	SIMARD_STATE_ROOT=/tmp/simard-busy-live-root.XXXX cargo test --lib self_relaunch::gates	✅ PASS (exit 0)	test result: ok. 25 passed; 0 failed; gate no longer collides with the live daemon root — the isolated IsolatedStateRoot wins

Constraint checks: no stray print!/println! in changed code (only doc/comment references); no Bridge naming in new identifiers; structured tracing/OTel discipline preserved; fix is additive and scoped to the unit-test gate.

Fix count during outside-in testing: 0 — both scenarios passed on the first run. The PR branch behaves correctly: cargo test inside the canary gate now runs under a private, owner-only (0700) empty state root, so it can no longer race the live daemon's SIMARD_STATE_ROOT and abort with exit status 101. The red-canary crash-loop condition is resolved at the outside-in boundary.

Step 17b — Comprehensive Code Review (#4522 hermetic unit-test canary gate)

Verdict: APPROVE — no blocking issues. Reviewed the full diff (5 files; core logic in src/self_relaunch/gates.rs, +294) at PR head 95a7401.

Review checklist

Item	Result	Notes
Code quality & standards	✅	Intent-revealing names; RAII IsolatedStateRoot; no Bridge naming; no print!/println! (structured discipline preserved).
Test coverage adequate	✅	5 TDD tests cover the override, apply-after-scrub ordering, hijack-guard preservation, full-suite invariant, and 0700+drop lifecycle. 25/25 lib gate tests pass; clippy --lib --all-features clean.
No TODOs / stubs / swallowed exceptions	✅	None. IsolatedStateRoot::create() failure returns a fail-closed RED GateResult (never silently runs against the live root).
No unimplemented functions	✅	None.
Logic correctness	✅	See below.
Edge case handling	✅	tempdir-create failure, hijack re-injection, missing ambient var all handled.

Logic correctness — verified

1. Ordering guarantee holds. build_unit_test_command builds via scrubbed_command("cargo", …) (which runs env_clear() + re-injects the allow-listed live SIMARD_STATE_ROOT), then applies .env("SIMARD_STATE_ROOT", state_root) last. Command collapses duplicate keys to the final value, so get_envs() yields the isolated root — the tests assert exactly this, not an incidental value.
2. Fail-closed preserved. tempdir creation error ⇒ passed: false with a clear detail. /tmp unwritable reddens the canary rather than colliding with the live daemon. Correct.
3. Security guard intact. The new override does not touch is_hijack_class_env; LD_PRELOAD-class vars remain denied even when listed in canary_env (isolation_does_not_reinject_a_hijack_var_into_unit_test_gate proves it). Deny-by-default floor + deny-over-allow unchanged.
4. Gate not weakened. Still invokes the full cargo test --manifest-path … --target-dir … CARGO_BUILD_JOBS; no narrowing/skip. Asserted structurally.
5. unwrap/expect confined to tests — zero in the non-test region.

Non-blocking observations (no action required)

• The 0700 set_permissions hardening is #[cfg(unix)]; on non-unix the explicit mode-pin is skipped (tempfile still creates 0700 on unix by default). The gate is a systemd/unix deploy path, so this is appropriate — noted only for completeness.
• Since the unit-test gate now always overrides SIMARD_STATE_ROOT, keeping that name in the shared canary_env allow-list is redundant for this gate (still required for the process-probe gates). Harmless and intentional given the allow-list is cross-gate.
• Pre-existing (not introduced here): the failure detail uses format!("tests failed (exit {}): …", output.status) where ExitStatus Display already prints exit status: N, yielding a mild "exit exit status:" doubling. Out of scope for this PR.

Docs

Reference doc canary-unit-test-gate-hermetic-isolation.md (+313) plus cross-links in the convergence reference, howto runbook (step 4b), and index are accurate and consistent with the code. Good root-cause narrative (exit 101 = test-binary abort vs 1 = assertion).

Conclusion: Additive, non-breaking, root-cause fix with strong TDD coverage and preserved fail-closed/security invariants. All checklist items pass. Ready to proceed.

Step 17c — Security Review (#4522 hermetic unit-test canary gate)

Verdict: APPROVE — no security findings that block merge. This change is net security-positive: it closes an ambient-environment hijack vector in canary gate subprocesses and adds owner-only temp isolation. Reviewed PR head at src/self_relaunch/gates.rs.

Security requirements — all met

Area	Result
Injection (command/shell)	✅ cargo test args passed via .arg(...), no shell interpolation; state_root is a tempfile-generated path, not attacker-influenced
Env-hijack hardening	✅ env_clear() + deny-by-default allow-list; is_hijack_class_env (case-insensitive) refuses LD_*/DYLD_*/GIT_SSH*/BASH_ENV/ENV/SHELLOPTS/BASHOPTS/IFS even if re-listed in canary_env (SEC-D3 defense-in-depth)
TOCTOU / symlink	✅ Isolated state root is a unique random-named tempfile::TempDir, pinned 0700 (owner-only) so no other user can pre-seed/observe it
Sensitive-data handling	✅ No env values logged; gate detail is truncated stderr routed through bound_gate_detail (credential-redacted, bounded). scrub_gate_env logs nothing
Fail-closed	✅ Tempdir-create failure returns a RED GateResult, not a swallowed error — no silent-pass path
Lifecycle / leak	✅ RAII drop removes the per-run dir; no per-tick temp-state accumulation
AuthN / AuthZ	N/A — no auth surface touched

Positive security properties introduced

• Deny-by-default env floor: only a fixed BASE set + trusted canary_gate_env_allowlist() (SIMARD_HOME, SIMARD_PROMPT_ASSETS_DIR, SIMARD_STATE_ROOT) survive; everything else (including loader/shell hijack vars) is dropped.
• Last-wins override pins the isolated SIMARD_STATE_ROOT after scrub re-injects the live value, so the live cognitive-memory root can never leak into cargo test — verified by the hijack-guard + apply-after-scrub tests.
• Code-enforced hijack denylist backs the docstring guarantee, so the guarantee survives a future caller sourcing canary_env from a less-trusted origin.

Non-blocking notes (no action required to merge)

1. Hijack denylist is not exhaustive of build-influencing vars — it omits Rust/Cargo build wrappers (RUSTC_WRAPPER, RUSTFLAGS, CARGO_BUILD_RUSTC) and other loader-ish vars (PYTHONPATH, PERL5LIB, NODE_OPTIONS). Harmless today because deny-by-default only admits BASE + the trusted allow-list; the guard is defense-in-depth for a future untrusted canary_env. If canary_env ever sources from operator input, consider extending is_hijack_class_env to cover RUSTC_WRAPPER/RUSTFLAGS/CARGO_BUILD_RUSTC.
2. CARGO_HOME/RUSTUP_HOME inherited from ambient — a poisoned CARGO_HOME/.cargo/config.toml (e.g. [build] rustc-wrapper=…) could steer the unit-test build. In-scope threat model is the daemon's own trusted systemd env, so acceptable; worth a one-line doc note that CARGO_HOME must be trusted.
3. Redundant set_permissions(0700) after tempdir() has a negligible TOCTOU window, but tempfile already creates 0700, so it is a safe no-op re-affirmation (explicitly documented as defense-in-depth).

Conclusion: No new vulnerabilities. Sensitive data is not exposed. Injection and env-hijack surfaces are hardened, not widened. Approved from a security standpoint.

Step 17d — Philosophy Guardian Review (#4522 hermetic unit-test canary gate)

Verdict: COMPLIANT — approved. Reviewed the full diff (5 files; core logic in src/self_relaunch/gates.rs, +294) against the amplihack philosophy at PR head 95a7401.

Compliance checklist — all pass

• Ruthless simplicity achieved. The fix is the smallest thing that works: a single RAII guard (IsolatedStateRoot, one field wrapping tempfile::TempDir) plus a last-wins .env("SIMARD_STATE_ROOT", ...) on the already-scrubbed command. No new abstraction layers, no config surface, no indirection. The root cause (canary cargo test racing the live daemon's cognitive-memory root → exit 101) is solved directly rather than papered over.
• Bricks & studs pattern followed. IsolatedStateRoot is a self-contained brick with a minimal public seam: create() -> io::Result<Self> and path() -> &Path. Lifecycle (unique tempdir, 0700, auto-removal) is fully encapsulated; the drop-based cleanup means callers cannot leak or misuse it. build_unit_test_command is a pure, testable stud that the convergence tests connect to via Command::get_envs without spawning a real build.
• Zero-BS implementation. No stubs, no faked APIs, no swallowed exceptions. Every failure path is real and surfaced: tempdir-create failure returns a fail-closed RED GateResult (passed: false) rather than skipping the gate; cmd.output() distinguishes non-zero exit (truncated stderr) from spawn failure. Every unwrap/expect is confined to #[cfg(test)] code; the non-test region has zero.
• No over-engineering. Resisted the temptation to build a general "sandboxed gate environment" framework. Scope is exactly one gate and one env var. The unix-only 0700 set_permissions is justified defense-in-depth (does not silently depend on the dependency's default) and is appropriate for the systemd/Linux self-deploy path — not premature portability work.
• Clean module boundaries. The override is layered after scrub_gate_env, preserving the existing deny-over-allow allow-list discipline; the isolation concern is additive and does not entangle with or weaken the hijack-guard logic. A dedicated TDD test asserts the isolated root wins over a re-injected allow-listed live value purely by ordering.

Non-blocking observations (no action required)

• The SIMARD_STATE_ROOT allow-list entry is now effectively redundant for this gate (the override always wins), but it is harmless and removing it is out of scope.
• 0700 hardening is #[cfg(unix)]-gated — correct for the target platform; a Windows path would need a separate ACL story if ever supported.

Philosophy status: COMPLIANT. The change embodies ruthless simplicity, fail-closed safety, and a clean regeneratable brick. Ready to proceed.
