Summary

• Add a retained-fixture probe for two accepted native 2.2.5 interruptions and native session.wait calls across successive executions. The fixture injects tool-error events and intentionally delays delivery of the first completed wait result.
• Require a fresh native wait, six directly invoked quarantine guards to remain closed while its result is held, and a separate peer session to reach the authenticated localhost provider with a synthetic marker.
• Reuse the auxiliary probe's bounded authenticated runtime and strengthen its cleanup reporting. Reject unexpected or ambiguous plugin inventories. Run the new probe in the 2.2.5 CI job; other versions are not qualified.
• Do not enable the gateway or infer naturally occurring scheduling, settlement of independent processes, or security protection.

Validation

• 148 focused native-settlement, auxiliary, profile, boundary and direct-shell probe tests; Ruff; Python compilation; Make runtime contract; documentation/reachability checks; static pre-commit hooks. Full make validate is deferred to isolated CI because local tests share a fixed-name configuration-lock registry.
• Restricted macOS tmux runs of the selected OpenCode 2.2.5 executable (SHA-256 abe4d88594bffb12b364375b8a6732d2d1f7a977195ed1a35c5c76f8e89c9e0e) observed both native interruption acceptances and both native waits. The reusable script and documented Make target passed, with checked teardown and all case/version roots retained.
• A separate retained baseline control using the pre-fix adapter from c52a883 observed guard reopening after the delayed first native wait with only one wait; the fixed adapter stayed closed until a second wait was delivered. The error events and wait delay were injected; guard checks were direct callback invocations.
• Independently tested OS policy denied outside and symlink-target writes, non-loopback connections and external signals, while allowing owned fixture writes and loopback. This is bounded evidence, not complete containment or proof that no process escaped the checked group.
