Problem

Claude workflow members waiting for a concurrency slot appeared to be running, with a working timer and a Thinking placeholder. Reproduced with the real web app and a native Claude workflow containing three agents per phase on a host with two execution slots.

Change

Treat a Claude start snapshot without a valid startedAt as queued. Timestamped starts and progress remain running. Existing projection and client handling then preserve a null start time until execution begins. Update test fixtures that represent running members to include their start times.

Scope and approval

Fixes #25307

Triaged bug via the automated issue flow. #25307. No contract or client changes.

Verification

• Regression test failed before the fix: expected queued, received running for start without startedAt; it now passes, including transition to timestamped start and progress.
• Focused parser and Claude adapter suites: 250 tests passed. vp run check:changed passed both before and after merging main: format, lint, knip, GraphQL, typecheck and all 250 focused tests.
• Independent Codex and Claude reviews found no code blockers.
• Native Claude before/after runs: queued third child changed from running with synthetic timing to pending with null start time; it became running with an execution timestamp after gate release (visible in the narrow recording and persisted events). Both six-member workflows completed.

Evidence uses base 6a3a460b09 and fix 9b36ce059c. The subsequent main merge does not change the three files in this PR. Wide browser: 1440×900 CSS/light, DPR 2 (saved PNGs compressed by preview to 1280×800). Narrow: 390×844 CSS/dark, DPR 2. Recordings show navigation and gate release. The wide after-transition recording ends while the third member is still queued; the narrow after recording shows slot acquisition. Full evidence index, runtime transcripts, fixtures and scripts.

Fixture	Before · 6a3a460b09	After · 9b36ce059c	Diff0	Diff >16/channel	Recordings
Queued member, wide/light					Before / After
Running member, wide/light; transition narrow/dark					Before / After
Queued member, 390/dark					Before / After
Completed, wide/light					Before / After

Visible differences: queued members lose the running timer and Thinking placeholder; wide lineage shows Queued. The existing generic child footer can still say Working without a timer, and aggregate workflow counts remain working. The live runs also differ in timestamps, durations, generated titles, sidebar history, branch labels and prompt gate paths; the raw pixel diffs include those differences and are supplementary evidence, not an isolated pixel comparison.

Proof audit found no code correctness issue and identified the missing wide R transition recording. The R transition is verified by the narrow recording plus wide held-state captures and persisted events. A wide after slot-acquisition transition was not captured. Not verified in a real client: progress without startedAt (native Claude did not generate it), native mobile, desktop shell, remote/relay/tunnel connections. The parser regression covers progress; shared contracts and client handling are unchanged.

Models: Claude Opus 5.5 and GPT-6.1-Sol through the T3 Code Claude and Codex harnesses.

Approvability

Verdict: Approved at 8a1e76e

Macroscope's review found this PR approvable — Claude workflow members now remain pending until a valid execution start timestamp arrives, avoiding premature running indicators and timers. The change is confined to progress interpretation and preserves existing execution scheduling.

Walkthrough

Claude workflow members with start state and no valid startedAt are now mapped to queued. The adapter maps progress to running and returns the parsed start time. Tests cover state transitions and timestamp handling across workflow snapshots.

Explanation

The description includes all required sections. It explains the problem and reproduction, the implementation, scope and issue linkage, focused verification results, limitations, evidence, and the agent model and harness.

Full details: Linked Issues check

Explanation

Issue #25307 requires a Claude member with state: "start" and no valid startedAt to remain queued. claudeWorkflowProgress.ts applies that rule and preserves a valid startedAt. A timestamped start maps to running. progress also maps to running through the existing fallback. The added parser test verifies the queued-to-running transition. The changed adapter fixtures now give running start members a start time. The PR evidence reports that existing projection keeps the queued start time null until execution begins.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff contains only changes in the Claude workflow parser and its tests. The parser change implements issue #25307. The parser tests cover the new state transition and stale-frame behavior. The adapter fixture updates keep test data consistent with the new distinction between scheduled and running members. No unrelated production code, contract change, or client change appears in the diff.

Exercise start without startedAt in the adapter projection test.

The adapter test asserts pending for a provider queued state, not for a start state with no startedAt. Its later start case includes an explicit timestamp. The fixture converts an omitted timestamp on start members to 0, so no adapter test covers this parser-to-projection path.

Evidence

Run three native Claude workflow members with two execution slots. Each performs 60 sequential echo commands to occupy its slot. Open waiting Member 3, inspect lineage, and watch it acquire a freed slot. Both sides use fresh synthetic state, the same viewport, and light theme. Videos provide the timing evidence; images show the corresponding queued state. Captures are cropped to exclude private metadata.
