fix(cli): preserve runtime and delegation observations by zatevakhin · Pull Request #18 · querymt/qmacp

zatevakhin · 2026-10-29T13:37:17Z

Preserve runtime observation health, cancellation receipts, and recovery evidence without treating self idle as task success.

Expose delegation lifecycle events and compact snapshots separately from tool dispatch.

Requires updated backend observation metadata. Companion backend: querymt/querymt#1109; desktop: querymt/querymt-desktop#308

Summary by CodeRabbit

New Features
- Delegation lifecycle updates appear in event streams and session inspection, separately from tool activity.
- Prompt, follow, and watch results include runtime observations and recovery details when available.
Bug Fixes
- Unknown or unavailable runtime observations are no longer treated as idle; affected waits and follow operations report errors.
- Cancellation results confirm only that a notification was sent, not that a run was terminated.
Documentation
- Clarified that session idle does not establish task success or descendant and process completion. Cancellation does not remove queued inputs or cancel child workflows.
- Documented the observation requirements for automatic delivery and idle waits.

Walkthrough

The change validates backend runtime observations before treating a session as idle and preserves runtime evidence in command results and recovery data. It adds delegation lifecycle events to live streams and compact inspection. Cancellation output reports local notification delivery without claiming remote termination.

Changes: Session Observation and Delegation

Layer / File(s)	Summary
Validate and retain runtime observations `src/commands.rs`, `src/session.rs`, `tests/agent_workflows.rs`, `README.md`, `skills/qmacp/*`	Commands validate observed runtime phases for delivery, idle waits, follow, and watch. Results and recovery data retain runtime evidence. Session summaries and phase filters use validated observations. Tests cover unavailable observations, timeouts, recovery, and phase filtering.
Forward and inspect delegation updates `src/client.rs`, `src/events.rs`, `src/session.rs`, `tests/agent_workflows.rs`, `README.md`, `skills/qmacp/cli.md`, `skills/qmacp/sessions.md`	The client emits compacted delegation notifications, and compact inspection includes delegation snapshot records separately from tool status. Tests cover notification delivery and delegation snapshots.
Report cancellation notification delivery `src/commands.rs`, `tests/agent_workflows.rs`, `README.md`, `skills/qmacp/SKILL.md`, `skills/qmacp/cli.md`, `skills/qmacp/control.md`	Cancellation results use `cancellationState: "notification_sent"` to report local notification delivery. Documentation and tests distinguish this result from remote termination and from discard or close operations.

Merge Risk: Low · up to 3f0ac

The change is mergeable with a small test improvement: assert that compact inspection contains exactly one tool so delegation entries cannot silently appear there. The previously reported null-phase mismatch is fixed.

Full details: Title check

Explanation

The title "fix(cli): preserve runtime and delegation observations" names the main change. The changeset keeps runtime observation metadata and delegation updates in CLI output. It also stops treating self-session idle as task success and changes cancellation to report a notification state. The title covers the core theme but not the cancellation and idle-semantics changes, which is acceptable for a title.

Full details: Docstring Coverage

Explanation

Docstring coverage is 8.33% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 24 functions across 5 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

⚠️ Potential issue | 🟡 Minor | 💤 Low value

The new runtime.get("phase").map(...) maps an explicitly null phase to unknown; the documented missing-phase representation is null.

Its summary reports phase: unknown instead of retaining the absent phase as null, changing discovery output and --phase unknown results.

This can occur when: A listed session has runtimeStatus: {"phase": null}.

Add an unavailable tools session to the discovery fixtures.

1167-1169: Trivial · Functional Correctness · Quick win

Add an unavailable tools session to the discovery fixtures.

No discovery fixture pairs phase tools with observation.availability unavailable. A regression that accepts that pair would still pass the tools assertion, because the current fixtures never produce it. The summary phase for an unavailable observation is unknown, so the new session also belongs in the unknown expectation.

Append the fixture to the end of listed. The unfiltered branch reads sessions by index, so appending keeps the existing indices unchanged. Keep the new session out of the tools expectation.

Assert the full compact tools array.

954-956: Trivial · Functional Correctness · Quick win

Assert the full compact tools array.

The test checks only result["tools"][0]. The fixture contains one audit tool_call_end for dispatch-1, so the compact tools array holds one entry. An extra entry appended after dispatch-1, such as one derived from delegationUpdates, would pass these assertions. A length check closes that gap.

                 assert_eq!(result["tools"][0]["id"], "dispatch-1");
