Summary

Part 3 of 5: splits sanitize, announce and the launch send out of TaskService.createUnderTaskTreeLifecycleLock in place, with no behaviour change. The method drops from CC 88 to CC 78. On top of part 2. 94 changed lines. The moved code keeps its indentation, so git sees few changes.

Steps in this part

  • sanitizeTaskLaunchCheckout still runs before the metadata emit.
  • announceAndInitTask emits the metadata, reads the secrets, then calls registerExternalBackgroundInit.
  • sendTaskLaunchPrompt makes the send admission with no await before it, in the same continuation as registerExternalBackgroundInit.

Rules every part keeps

  • The method keeps await using _lock = await this.mutex.acquire(). Inside that scope, a bare return promise releases the global mutex before the promise settles. So every call from the method to a step is await or return await, and no step acquires the mutex, which is not reentrant.
  • The steps form a chain: each step calls the next one directly after its own last await. So no collaborator call runs a microtask later than in the inline code. Only the result of the method resolves later, at approximately 2 microtasks per chain level. The mutex therefore releases that much later, at the same logical point.
  • make crap-check against the parent commit reports 0 violations, with and without coverage. Every new function scores CC 8 or less.
  • bun test on the taskService, ledger, workspaceTurnManager, workflows, tools and workspaceService suites: 4,968 pass, 0 fail. These suites include the 27 tests from 🤖 tests: cover createUnderTaskTreeLifecycleLock paths before the split #7701.

… announce and send

Moves the launch tail of TaskService.createUnderTaskTreeLifecycleLock, after
the checkout materialized, into a chain of three steps:
sanitizeTaskLaunchCheckout, announceAndInitTask and sendTaskLaunchPrompt.
The materialized checkout travels in a readonly TaskLaunchCheckout record.
Each step starts the next in the same tick as its own last await, so the
sanitize still ends before the metadata emit, and the send admission still
runs in the same continuation as registerExternalBackgroundInit. The method
calls `return await this.sanitizeTaskLaunchCheckout`, so the global mutex
releases only after the launch result settles.
