19/**
20 * One per repository: its agent tasks. A task is a goal a person gives one of
21 * their agents. Each run of it starts a fresh sandbox as the agent, installs
22 * the runtime, runs it with the person's model access through the model proxy,
23 * pushes the work to the task's branch as the agent and opens a pull request.
24 *
25 * Runs advance in the alarm, a step at a time: boot → install → agent → finish.
26 * Nothing here checks who may do what: the Worker does (agentic/tasks.ts),
27 * and `boot` re-checks the person and the agent before every run.
28 *
29 * A pull request's agent reviews (agentic/review.ts) are a task of kind
30 * `review`, one per pull request, and each review is a run of it: the sandbox
31 * is read-only, and instead of pushing, `finish` posts the findings as a review
32 * and completes the Agent review check run.
33 *
34 * A person's project coordinator (agentic/coordinator.ts) is a task of kind
35 * `coordinator`, one per person, and each post it handles is a run of it: the
36 * sandbox is read-only, and `finish` validates the actions block in its final
37 * message and applies it as that person (reply, start tasks, message or stop
38 * their tasks, rewrite the memory). Tasks it starts carry a token budget.

2121 * A run's finish. The agent's clone is the agent's: anything in it (hooks, config, filters) is its to set, so it
2122 * is only touched in a jail with no network and no credential, which commits what's left and writes a bundle of
2123 * the new commits. Outside, the sandbox's checkout (which has the credential) takes the bundle's objects as data
2124 * and pushes them, with no hooks and no fsmonitor: the sandbox's own git credential (the agent's, through branch
2125 * protection and push protection) does the push.
