Scout execution-brief items 12-14 and 16.

orchestrator queue (P2, 12-14): persistent SQLite queue reusing existing coordination contracts. States queued→claimed→running→succeeded|failed|cancelled; atomic claims via BEGIN IMMEDIATE (two-connection test proves exclusion); lease+heartbeat+orphan sweep (expired lease requeues until max_attempts then fails closed); idempotent --key resubmit; collect-before-report with incomplete stragglers + --strict; payload screened for secrets at write time; queue fanout with physical (repo,worktree)+(repo,branch) locks and file_collisions refusal; plan --files repeatable flag emitting plan units.

switch (P2, 16): JSONC trailing commas (string-aware strip, {,} and [1,,2] still fail loudly); verify-env with explicit PASS/WARN/FAIL per managed file, exit 1 on FAIL.

Tests: orchestrator 154 passed/27 subtests, switch 160 passed. ruff clean.

The provided code snippet is a Python script for a CLI tool called devin-orchestrator. It includes various functionalities such as planning, queuing, and managing tasks. The script is designed to be used in a Devin workspace, which is a development environment for Python projects. The tool is used to manage the execution of tasks, including API, UI, and tests, and to coordinate the execution of these tasks across multiple workers.

Here's a breakdown of the key components and functionalities:

1. Planning:

   • The plan command is used to compute a worker plan based on a JSON specification. The specification includes details such as the kind of task (implementation), the number of independent units, whether the task needs write access, the estimated scope, and a summary.
   • The --explain option provides a detailed explanation of the plan.

2. Queueing:

   • The queue command is used to manage the task queue. It supports various operations such as submitting a unit, claiming a unit, leasing a unit, collecting units, sweeping orphaned units, collecting units before the aggregate report, and checking the status of a task.
   • The --files option is used to specify the files that the unit touches, which helps in avoiding collisions with live tasks.

3. Installing Skills and Rules:

   • The script installs the devin-orchestrator skill and always-on rule into a Devin workspace. This allows the skill to be used in the Devin environment.

4. Behavioral Matrix Testing:

   • The pytest -q command is used to run a behavioral matrix test suite. The suite includes tests for different scenarios, such as trivial, units, nested, and other combinations.

5. Command-Line Interface:

   • The script provides a command-line interface with various subcommands such as plan, queue, install, and pytest. The --files
