test(policy): a scoped test thread's reload never writes the process policy - #8588
A test thread holding an install_scoped live policy no longer writes the process-global live policy when it reloads. test(approval): model the legacy Always-allow import in the stub engine #8568's core-flow test saves "Always allow" through add_auto_approve_tool, and that save can no longer leak create_workflow into the shared policy that sibling gate tests read.
Test-only behaviour; production is unchanged.
Problem
add_auto_approve_tool → apply_autonomy_settings → live_policy::reload_from rebuilds the process-global policy whenever one is installed.
test(approval): model the legacy Always-allow import in the stub engine #8568's core-flow test scoped its own policy with install_scoped, which only redirects reads. So if another test in the binary (bootstrap, or the live-policy tests) had installed the global policy, the test's allowlist was written into it and outlived the test. Later gate tests could then see create_workflow as a legacy grant.
Solution
reload_from (security/live_policy.rs) returns early, under cfg(test), when the calling thread holds an install_scoped override. This is the contract install_scoped already documents: sibling tests must never observe the scoped policy.
#[tokio::test] uses a current-thread runtime, so the save path runs the reload on the test's own thread.
No production thread holds an override.
Submission Checklist
Tests added or updated (happy path + at least one failure / edge case) per Testing Strategy: a_reload_on_a_scoped_thread_leaves_the_process_policy_alone.
It installs a global policy, so the check is not vacuous.
It reloads with create_workflow allow-listed from a scoped thread, then asserts a sibling thread's current() doesn't contain the entry.
Diff coverage ≥ 80%: the new branch runs in the new test and in the core-flow test.
N/A: no feature row added, removed or renamed in docs/TEST-COVERAGE-MATRIX.md.
N/A: no matrix feature IDs affected; the review thread is listed under Related.
No new external network dependencies introduced.
N/A: no release-cut surface changes (docs/RELEASE-MANUAL-SMOKE.md).
security::approval:: + security::live_policy::, one process, two runs
197 passed, 0 failed, both runs
Rebase check on 7d7f2fa (CF-W1-fu024-1, 6140034): fmt green; cargo check --locked green with and without security-module; the new test passes, and its red control fails at "a scoped test's reload must not reach the process-global policy"; security::approval:: + security::live_policy:: in one process: 199 passed, 0 failed. Layout is red only on main's own files. The branch still merges cleanly onto d8f23f5, which touches none of these files.
Impact
Test isolation only. The approval and live-policy suites no longer share an allowlist through the global policy.

Summary by CodeRabbit
Bug Fixes
Reloading a security policy while a temporary, thread-scoped override is active now leaves the process-wide policy unchanged, preventing the reload from affecting other threads.
Tests
Added regression coverage confirming that a scoped policy override remains isolated from sibling threads when a reload is attempted.

Diagnostics and supporting details
Full summary
Pull request purpose (title): test(policy): a scoped test thread's reload never writes the process policy. The change is `cfg(test)`-only; production behavior is unchanged. `reload_from` returns early when the calling thread has a scoped override, so a scoped thread's reload (for example a save of "Always allow" via `add_auto_approve_tool`) can no longer leak `create_workflow` into the shared policy that sibling gate tests read. A new regression test installs a process-global policy plus a thread-scoped one, reloads with `create_workflow` allow-listed, and asserts a sibling thread's `current()` does not contain the entry. The latest-push-delta is unavailable, so this review describes the whole pull-request rather than any incremental push.

Completeness: Complete Test assessment: No supported feature-to-test mapping was available; this does not mean tests are absent or passed.
What changed
In `crates/openhuman-core/src/security/live_policy.rs` (`reload_from`, adjacent to `crates/openhuman-core/src/security/live_policy.rs#pub fn generation() -> u64 {`), a `#[cfg(test)]` early return now checks `TEST_POLICY_OVERRIDE` and, when the calling thread holds a scoped override, logs a `tracing::trace!` and returns before touching the process-global `STATE`. The doc comment records the scoped-thread contract. In `crates/openhuman-core/src/security/live_policy_tests.rs`, the sibling test-layout file containing `crates/openhuman-core/src/security/live_policy_tests.rs#fn scoped_policy_is_thread_local_and_restored() {`, a new `#[test]` `a_reload_on_a_scoped_thread_leaves_the_process_policy_alone` takes `TEST_ENV_LOCK`, installs a global policy, installs a scoped one, reloads with `create_workflow` allow-listed, and asserts a spawned sibling thread's `current()` excludes it. Two files, +41/-0.
Features
Modified — Scoped-thread reload isolation in live_policy::reload_from: Under `cfg(test)`, a thread holding an `install_scoped` override now short-circuits `reload_from` before the process-global policy swap, so scoped test threads no longer mutate the shared policy that sibling tests read; a trace line records the skip. No production path is altered, since no production thread holds an override and the branch is compiled out of production builds. (crates/openhuman-core/src/security/live_policy.rspub fn generation() -> u64 {)
Tests
No supported feature-to-test mapping was produced. Test execution is not inferred.
Findings

Before merge

Agent review details
critique
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: Critique lane answered with no findings: the early return mirrors the existing `TEST_POLICY_OVERRIDE` short-circuit in `current()`, is gated on `#[cfg(test)]` so production behavior is unchanged, and the only production caller of `reload_from` (`config/ops/agent.rs`) is outside the `cfg(test)` branch. Caveat noted: not every caller of `reload_from` could be inspected, but no in-tree caller was shown to rely on a scoped thread also updating the global policy.
Lane summary: The change adds a test-only early return in `reload_from` so a thread holding an `install_scoped` override does not touch the process-global policy. It mirrors the existing `TEST_POLICY_OVERRIDE` short-circuit in `current()`, is gated on `#[cfg(test)]` so production behaviour is unchanged, and `install_scoped`/`TestPolicyGuard` are already defined earlier in the module. The only external caller of `reload_from` in production code (`config/ops/agent.rs`) is outside the `cfg(test)` branch, and the new test file already covers the scoped-thread case. I found no defects in this file. _The code index is behind this pull request (indexed at `24acae93c0e3`), so retrieved context may be out of date._
security
Conclusion: Success
Scope reviewed: all assigned evidence
Positive: Security lane answered with no findings: the change is a test-only early return reading a thread-local that production builds do not have, matching the existing override pattern used by `current()`, with no new untrusted input, network, or permission surface.

Walkthrough
In test builds, reload_from returns without reloading the process-global policy when the calling thread has an install_scoped override. A regression test checks that a sibling thread does not observe create_workflow from that reload.
Changes: Scoped Policy Reload
Layer / File(s)
Summary
Reload guard and regression test crates/openhuman-core/src/security/live_policy.rs, crates/openhuman-core/src/security/live_policy_tests.rs
reload_from checks for a scoped policy override before reloading. The regression test verifies that a sibling thread's process-global policy does not gain create_workflow from that call.
The change only affects test builds and does not alter production behavior. A prior suggestion to strengthen the regression test's assertion that the global policy is not replaced may still be open. This is a small follow-up and does not block merging.

Assert that the global policy is not replaced.
A scoped reload that installs a default policy would pass this assertion. Retain the installed Arc and compare it with the sibling thread’s policy.
