A rabbit checks the task’s next turn,
For payment clues and actions stern.
The host replies with yes or no,
Then onward does the task request go.
New contract lines are neatly sown,
The rabbit thumps: the gate is known.

When a configured ConsequenceHost disconnects or restarts before Review, TinyBus reports NameHasNoOwner; similarly, a process owning the name but exposing a broken endpoint reports UnknownObject or UnknownInterface. Classifying all three as NotServed makes screen preserve approve: true, so an irreversible or paying action proceeds precisely while its policy reviewer is unavailable. Only a reviewer established as never configured should fail open; loss or misconfiguration of an expected reviewer must produce Failed and decline the action.

The paused action is snapshotted before awaiting the host, but the eventual continue_task consumes whichever approval pause currently belongs to that task ID. With two concurrent ContinueTask { approve: true } calls, both can review checkpoint A; if one returns first and the task reaches checkpoint B before the other returns, the delayed approval is applied to B even though the host never reviewed B. Revalidate or atomically consume the exact reviewed checkpoint before resuming, and cover concurrent calls through the module's in-memory bus.

Bind approval decisions to the reviewed pause.
review_approval snapshots the current action and target before awaiting the host, but tasks.continue_task receives only the approval boolean. If one request resumes the task and it reaches a later NeedsApproval pause before a second request is dispatched, decide takes the later state.resume without checking the reviewed action or target. The second request can therefore approve an action that the host did not review.
Carry a pause identity or generation into decide, and atomically reject the continuation when it does not match the current pause before taking state.resume.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Use a newer minor in the "newer, still-compatible module" example.
Line 56 labels (2, 19) as "a newer, still-compatible module". That value is now the shipped version from Line 55, so the example no longer shows a newer module. Lines 50-52 have the same problem: they say a module reporting (2, 19) has "something newer". Use (2, 20) in both places.
Proposed fix
-assert!(is_compatible((2, 19))); // a newer, still-compatible module
+assert!(is_compatible((2, 20))); // a newer, still-compatible module📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Part of tinyhumansai/openhuman#7328 (phase 7, item 3: wire tinycomputer consequence/payment gates into the host approval/policy path).
The module classified irreversible and paying controls and paused tasks before them, but the only gate on the pause was
ContinueTask { approve: true }, with no seam for the host's security policy to rule on it.ai.tinyhumans.tinycomputer.ConsequenceHost(tinycomputer_bus::consequence_host), memberReview(task, action, target, module classificationirreversible|payment). Contract 2.19.ContinueTaskwithapprove: trueon aneeds_approvalpause callsReviewfirst; a denial converts the approval into a decline.Tests: wire-form and identity tests in the bus crate; link tests (allow, deny, decline passthrough, nothing pending, failing host, unserved host) and real-bus port tests in the module. clippy 1.98 -D warnings clean.
