fix(client-runtime): map cancelled and interrupted subagent terminal statuses

[Exotic209093]

Codex subagents that complete with 'cancelled' or 'interrupted' status were falling through to 'running' because TASK_COMPLETED_STATUS only covered completed, failed, and stopped. This adds both missing entries so the fold correctly marks them as terminal.

Fixes #11164

Summary by CodeRabbit

• Bug Fixes
  • Subagent tasks that are cancelled or interrupted now display the correct terminal status instead of being marked as completed.
  • Task summaries are preserved as results, and completion times are recorded for cancelled and interrupted tasks.

Approvability

Verdict: Approved at 62e0f58

Macroscope's review found this PR approvable — This is a focused client-runtime bug fix that maps existing cancelled and interrupted completion statuses to their corresponding terminal states. It adds targeted tests and does not affect schemas, defaults, infrastructure, security, billing, or static-analysis configuration.

Extend the task-completion wire contract

These branches cannot handle normal production events because TaskCompletedPayload.status in packages/contracts/src/providerRuntime.ts still permits only completed, failed, and stopped; current Codex interruption paths also emit task.updated, not task.completed. The new tests bypass that contract with a cast, so they exercise fabricated activity rows while the reported live task.completed scenario remains unsupported. Add these statuses to the contract and normalize them through the relevant adapter and ingestion paths before relying on this client mapping.

📝 Walkthrough

Walkthrough

The task completion contract now accepts cancelled and interrupted statuses. The runtime maps them to matching terminal agent states. Tests verify the status, summary result, and completion timestamp.

Explanation

Issue #11164 requires these mappings: pendingInit→pending, running→running, interrupted→interrupted, completed→completed, errored→failed, shutdown→cancelled, and notFound→failed. The pull request adds cancelled and interrupted to TASK_COMPLETED_STATUS and adds focused tests for those two payload values. The reviewed changes do not implement or test the required Codex mappings for pendingInit, errored, shutdown, or notFound.

🟡 Minor · Project agentsStates.status before emitting task.progress. · CodexAdapter.ts:1256-1285

apps/server/src/provider/Layers/CodexAdapter.ts:1256-1285
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Project agentsStates.status before emitting task.progress. A reachable collabAgent/item payload carries raw CollabAgentStatus values in agentsStates, but mapCollabAgentEvent reads only the item summary and emits task.progress. It therefore drops lifecycle updates, so an agent can retain its prior running state instead of applying pendingInit→pending, running→running, interrupted→interrupted, completed→completed, errored→failed, shutdown→cancelled, or notFound→failed.

Map the raw status at this Codex boundary before folding the event. This is separate from the client-runtime TASK_COMPLETED_STATUS mapping, which handles only task.completed payload statuses and cannot process these raw collabAgent/item values.

Closing: #11164 is about updateSubagentStates in the orchestration-v2 branch (#2829), which is not on main. On main no adapter emits task.completed with cancelled or interrupted: the Claude SDK status set is completed/failed/stopped, xAI normalizes cancelled to stopped, and Codex routes collab agents through task.updated, where both statuses are already known. The change is harmless but does not fix anything, and the description describes behavior that does not occur.
