fix(pause-point): abort on synchronous trigger rejection and key expired guidance on MethodEntryCount - #2587
Merged
Conversation
…e it runs A --trigger command that Unity refuses in preflight reports the refusal on stdout as a normal Success:false response, so the stderr error-envelope check never saw it and the wait ran out the marker's whole lifetime before reporting PAUSE_POINT_EXPIRED with the real cause buried in Details.TriggerResult. Read RejectedBeforeExecution and Message off the triggered command's own response and abort on the same terms as a CLI-side rejection: the command performed no action, so the marker can never be hit by it. A rejection owned by the awaited marker itself still does not abort - that is the marker having been hit before the trigger ran. Quote the rejection's own reason in PAUSE_POINT_TRIGGER_FAILED instead of asserting argument parsing or an unknown command name, state a failed trigger at the front of an expired or timed-out message, and pick the recovery step that matches where the rejection came from.
…having happened Every reason the shared non-firing hint listed assumed the awaited event occurred and the marker still missed it, so an agent whose collision or input simply never happened read the cached-dispatch and pre-bound-delegate explanations as the diagnosis and went looking for a patching bug. State the simplest cause first: check the game state with execute-dynamic-code before suspecting dispatch. The hint is shared by the timeout and expired diagnoses, so both gain it.
…onse field The CLI could not tell "the trigger was refused before it did anything" from "the trigger ran and failed": both arrive as Success:false with only a message, and matching message text is exactly the brittleness RejectedByActivePausePointId was introduced to avoid. A refusal that no pause point owns - PlayMode simply not running, the common case for a --trigger - carried no structured signal at all. Add RejectedBeforeExecution to the four tool responses a --trigger can dispatch and set it only on the PlayMode preflight branch. Each tool now builds that response through a factory, so a mid-flight failure cannot claim the flag by copying the shape.
…ached dispatch An expired physics-message marker reported cached message dispatch as the leading explanation even when MethodEntryCount was a measured 0. That reads as "the patch was bypassed" and sends agents into recreate-the-GameObject workarounds, when a measured 0 is much better evidence that the collision or input the marker waited for never happened at all. State the game-state check first for an instrumented marker whose entry count is 0, and keep cached dispatch as the follow-up for a body that provably ran. An uninstrumented marker's 0 is unmeasured, so it keeps the previous guidance.
…uidance A successful enable only ever named the --trigger form as the way to wait, so a marker driven by physics, a timer, or a multi-step action read as needing a trigger command it has no single command for. await-pause-point has never required --trigger. Name the blocking wait without a trigger between the status read and the one-call trigger form, and say the same in the quick-check reference.

…usal The first recovery step told the caller to fix the --trigger value even when Unity had accepted the command as well-formed and refused it for Editor state, sending them to edit a command that was already correct. Branch it on the rejection's source the same way the third step already is: an envelope rejection keeps the trigger-value fix, a Unity-side pre-execution refusal says the trigger was valid and points at the state in its message.
The hint is shared by the timeout and expired diagnoses, and both reach it on a plain await-pause-point with no --trigger at all. Its opening clause claimed a trigger had fired, so the one case that most needs the patterns list was told they did not apply to it.

…g an argument problem pausePointTriggerRejectionReason fell back to "argument parsing or an unknown command name" whenever the trigger response could not be decoded. That fallback also covered every dispatch failure written to TriggerResult.Error -- a dropped connection, an unreachable Editor, a timeout -- so an EXPIRED or TIMEOUT wait whose trigger died mid-flight was told about an argument problem that never happened, which is the class of invented cause this work removes. The reason now reads the dispatch error first: the error envelope's Message when the stderr text is one, the trimmed raw text otherwise. The fixed text is used only when the failure produced no text at all. Also refresh two doc comments that no longer described the code: the stdout-rejection note now points at pausePointTriggerRejectedByUnityBeforeExecution, and pausePointTriggerFailedNextActions no longer claims only the --trigger value can be wrong.
… command The arming guidance's last sentence named "enable-pause-point --await --resume-play --trigger ..." without the binary, while the two sentences before it are complete `uloop ...` command lines. Prefix it the same way so the whole hint reads as commands.
…ger wait The troubleshooting note said a preflight-refused --trigger always aborts the wait, but the wait deliberately keeps running when RejectedByActivePausePointId names the marker being awaited: that refusal means the marker was hit before the trigger ran, which is the wait's success rather than a dead end. Name the exception and regenerate the .claude and .agents copies.
…own entry point The existing tests called the response factories directly, so reverting a use case to build its rejection response inline would have kept them green. Add tests that call SimulateMouseUiUseCase.ExecuteAsync, SimulateKeyboardUseCase.ExecuteAsync, SimulateMouseInputUseCase.ExecuteAsync and ReplayInputUseCase.ReplayInputAsync with PlayMode stopped -- the preflight rejection an EditMode run produces naturally -- and assert the returned response reports RejectedBeforeExecution. replay-input's ExecuteStart is private, so Start is driven through the public ReplayInputAsync. Each response is read from an already-completed task rather than awaited or blocked on, so a regression fails the test instead of hanging the EditMode suite.

Re-trigger cubic
…may be bypassed The expired message for a marker whose patch may be bypassed opened with "the armed method was never entered", stating as fact the one thing a zero MethodEntryCount cannot prove in that branch: if the dispatch bypassed the patch, the method can have run without the patch recording anything. Report the measurement instead -- the armed patch recorded no method entry -- and leave the explanations to the rest of the message.
…ever faulted The second recovery step spelled the await fallback with --trigger "<corrected trigger command>" for every trigger failure. After a Unity-side pre-execution refusal there is no correction to make: the command was well-formed and only the Editor state refused it, so the placeholder named an edit the caller cannot perform. Branch the step on the rejection source like the first and third already do, and reuse the same trigger command once the precondition holds.

Summary
Three pause-point guidance defects from the usability rounds, all of the same shape: the response
asserted a cause it had not observed.
--triggerUnity refused before it ran did not abort the wait. Unity reports apreflight refusal on stdout as a normal
Success:falseresponse, and the abort check only readthe stderr error envelope, so the wait sat out the marker's whole lifetime and then reported
PAUSE_POINT_EXPIREDwith the real cause buried inDetails.TriggerResult.MethodEntryCountwas a measured0, which reads as "the patch was bypassed" and sends agentsinto GameObject-recreation workarounds.
enable-pause-pointonly ever named the--triggerform as the way towait, so a marker driven by physics or a multi-step action looked like it needed a trigger command
it has no single command for.

Changes
RejectedBeforeExecution(bool) added to the four tool responses a--triggercan dispatch(simulate-keyboard, simulate-mouse-input, simulate-mouse-ui, replay-input), set only on the
PlayMode preflight branch. Each tool now builds that response through a factory, so a mid-flight
failure cannot claim the flag by copying the shape. Default

PAUSE_POINT_TRIGGER_FAILEDquotes the rejection's own reason instead of asserting argumentparsing or an unknown command name;
PAUSE_POINT_EXPIRED/PAUSE_POINT_WAIT_TIMEOUTstate afailed trigger at the front of the message; the third recovery step now depends on where the
rejection came from.
