Closes #1465 — AI-3745

What & why

The two Kiro Crew wait tests wrote the late sub-agent record on a fixed wall-clock delay. That delay cannot guarantee the write lands after the hook's first lookup, so a loaded macOS runner failed the no-wait test. The tests now pass the hook a clock that writes the record when the hook schedules its first poll delay. The record then lands strictly after the first lookup, and only if the hook waits. The hook's poll interval becomes KiroHookCommand.CrewParentPoll so the test can recognise that delay; behaviour is unchanged.

Where to look

FirstCrewPoll matches the poll timer by its due time. If the loop ever stops delaying on budget.Time, the Crew-wait test fails rather than passing silently.

Verification

  • KiroCrewSessionStartParentTests: 6/6 passed, three runs in a row.
  • Mutant (env-var gate removed, so a plain session waits): the no-wait test fails in 761 ms with but found ebc247c2-…, the same symptom as CI run 38602970545, now reproduced deterministically.

Summary by CodeRabbit

  • Tests
    • Improved coverage for Crew session-parent discovery when session records appear during polling, while confirming plain sessions remain unlinked.
    • Updated connection-ordering checks to wait for both cached agent data and daemon-list notifications before verifying results.
    • Improved consistency checks for recorded operation counts and payloads in local-control test scenarios.

A wall-clock delay cannot order the write after the hook's first lookup on a loaded runner; a clock that writes on the first poll timer does, and fires only if the hook waits.

📝 Walkthrough

The Crew parent lookup uses a named 100 ms poll interval. Integration tests create session records when the first matching poll timer is created. Other test updates synchronize remote-agent state assertions and scripted operation payloads with their call counters.

Changes: Crew parent polling

Layer / File(s) Summary
Name and use the Crew poll interval
src/Capacitor.Cli/Commands/Harness/KiroHookCommand.cs
The parent lookup uses the CrewParentPoll constant for its 100 ms delay. The lookup documentation now appears next to the method.
Trigger test records on the first poll
test/Capacitor.Cli.Tests.Integration/KiroCrewSessionStartParentTests.cs
The tests can supply a TimeProvider that writes a session record when the first matching poll timer is created. The Crew-launched and plain-session tests use this callback instead of fixed delays.

Remote agent test synchronization

Layer / File(s) Summary
Wait for cache and subscriber state
test/Capacitor.App.Tests.Unit/RemoteAgentsServiceTests.cs
The test's eventual condition requires both one cached agent and a daemon list received by the agents subscriber.

Scripted control operation synchronization

Layer / File(s) Summary
Record payloads and counters together
test/Capacitor.App.Tests.Unit/ScriptedLocalControlOps.cs
Operation methods now record each payload and increment its call counter under the same lock. Cancellation checks and scripted responses remain unchanged.

Priority: ⬇️ Low

Change: Other · Severity of issue fixed: Low

Suggested reviewers: realtonyyoung

Merge Risk: 🔵 Low · up to 1db66

The Crew tests may pass without exercising the late-record polling case, limiting confidence that they guard against the reported CI timing regression. The impact is confined to test reliability, so the PR remains mergeable with bounded follow-up.

Explanation

The pull request also changes RemoteAgentsServiceTests.cs to combine unrelated daemon and agent publication waits. It changes ScriptedLocalControlOps.cs to synchronize operation payload recording with call counters. Issue #1465 concerns only Kiro Crew parent-lookup test timing. The diff provides no connection between these changes and that issue.

Make Kiro Crew late-record tests follow the hook's first poll

🐞 Bug fix 🧪 Tests 🕐 10-20 Minutes

Grey Divider

AI Description

• Replace wall-clock record writes with writes triggered by the hook’s first Crew poll.
• Verify late records are found only when the hook waits, without changing production wait behavior.

High-Level Assessment

Keep the poll-triggered test clock. Unlike a fixed sleep, it orders the record write after the initial lookup and does nothing when the hook does not wait; a fully simulated clock would add complexity without improving that guarantee.

Write late Crew records on the hook's first poll

• Adds a TimeProvider that writes the sub-agent session record when the hook schedules its first Crew poll. Both wait tests use it instead of wall-clock tasks, making the parent-found and no-wait assertions independent of runner speed.

Expose the existing Crew parent poll interval to tests

• Names the 100 ms poll interval as an internal constant used by the existing delay, allowing tests to identify when the hook schedules a poll. Moves the parent resolver documentation to its method; wait behavior is unchanged.

Repository guidance requires both GitHub and Linear references in the PR description; accepted
precedent reinforces this requirement.

2. Kiro harness stays outside vendor folder 📘 Rule violation ⌂ Architecture
Description
The added CrewParentPoll timing logic remains in src/Capacitor.Cli/Commands/Harness/ instead of
the required Harness/Kiro/ directory for vendor-specific harness code. Future Kiro-only changes in
this file remain mixed with the generic command harness, so the prescribed assembly and directory
boundary is not maintained.
Code

Evidence
The changed lines add and use Kiro-specific Crew polling behavior in

vendor-specific harness logic to be placed under Capacitor.Cli/Harness/<Vendor>/, making this

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The changed Kiro-specific polling logic is located under `Commands/Harness/`, but vendor-specific harness code must live under `Capacitor.Cli/Harness/Kiro/`.

## Fix Focus Areas
- src/Capacitor.Cli/Commands/Harness/KiroHookCommand.cs[131-133]
- src/Capacitor.Cli/Commands/Harness/KiroHookCommand.cs[191-191]

## Recommended Fix
Move the Kiro-specific hook command into `src/Capacitor.Cli/Harness/Kiro/`, update its namespace to match the new directory, and update all imports and references. Keep the `CrewParentPoll` constant and its use with the relocated Kiro harness implementation.

3. The merge subject lacks its issue link 📘 Rule violation ⚙ Maintainability
Description
The PR commit subject Trigger the late Kiro Crew record from the hook's own poll does not end with

repository's merge-title format even though the change itself references issue 1465 elsewhere.

● Weak

The supplied commit message explicitly ends with (#1465), contradicting the finding that the subject
lacks an issue reference.

On the other two Qodo findings:

  • Kiro harness outside the vendor folder: KiroHookCommand is a command entry point, and CLAUDE.md puts those flat in src/Capacitor.Cli/Commands/Harness/. The constant belongs to the method that uses it.
  • Merge subject lacks its issue link: the commit subject does end with (#1465). The PR title deliberately carries no reference, because squash-merge appends the PR number and CLAUDE.md keeps issue references out of titles.
