Reapplied so the P0 fixes it carries are restored. The defects the readiness review found in it are fixed in the commits that follow; this commit alone is NOT shippable.

/**
|
|
* A stand-in for an agent's transcript, recorded by the host rather than by the app.
|
|
*
|
|
* The STA-3077 report's second failure is "a coding agent was resumed twice into
|
|
* one transcript". Driving a real coding agent inside the Docker OpenSSH fixture
|
|
* is not possible — no agent binary ships in the image and no provider session
|
|
* exists to resume — so the observable is moved to the thing that actually goes
|
|
* wrong: a second shell launching for a pane that already has one. Every shell
|
|
* the relay starts for a pane appends one line here, keyed by pane, so "resumed
|
|
* twice" reads as two lines for one pane key and needs no app-side reporting to
|
|
* be believed.
|
|
*
|
|
* The hook is installed before the first pane exists, and each test asserts the
|
|
* first launch was recorded before asserting no second one was — a hook that
|
|
* silently failed to fire would otherwise make every clause pass vacuously.
