fix(taskctl): verdict command fails — missing allowImmutable flag in Store.updateTask

[randomm]

Task Description

taskctl verdict fails with:

Cannot update immutable fields: pipeline. Use specialized methods for comments and pipeline events.

The adversarial agent calls taskctl verdict to submit its review, but the verdict command handler in tool.ts (line 976) calls Store.updateTask without the allowImmutable=true third argument, hitting the immutability guard on the pipeline field.

Root Cause

Same class of bug as #265 (retry/override). PR #266 fixed retry and override but missed verdict.

// Line 976 — missing true as third argument
await Store.updateTask(projectId, taskId, {
  status: "review",
  pipeline: { ...task!.pipeline, adversarial_verdict: verdictData, stage: "reviewing" }
})

Fix

Add true as the third argument:

await Store.updateTask(projectId, taskId, {
  status: "review",
  pipeline: { ...task!.pipeline, adversarial_verdict: verdictData, stage: "reviewing" }
}, true)

Quality Gates (Non-Negotiable)

• TDD: Write failing test first
• Coverage: test that verdict command succeeds on a task in adversarial-running stage
• Linting passes
• Local verification: all tests pass

Acceptance Criteria

• taskctl verdict successfully records an APPROVED verdict without throwing
• Test in packages/opencode/test/tasks/ verifies the verdict is stored and task transitions to reviewing
