Maps payload into provider models.

Slice `text` to its first `units` graphemes. Memoized across reveal ticks: * streaming blocks grow only by appending and the reveal target advances

* Find a model by provider and ID.

* Replace the in-memory buffer with the given text. Used when an upstream * minimizer rewrites the captured output after the raw bytes have already

Execute one cell. Caller invokes once per cell and aggregates results.

Check if a blob exists.

* Parse `input` into a {@link Patch}. `options.cwd` resolves absolute * paths inside headers to cwd-relative form; `options.path` provides a * fal

* Append one newline-terminated line. File and memory storage perform the * write synchronously in-body; indexed backends queue in call order. *

* Create an isolated instance for testing. * Does not affect the global singleton.

* Optional handler for keyboard input when component has focus

* Create a TaskTool instance with async agent discovery.

* Append a message as a child of the current leaf, then advance the leaf. * CompactionSummaryMessage / BranchSummaryMessage are rejected here — they

Close the transport

* Render the component to an array of physical rows at the given width. * The result is component-owned and `readonly` to the caller; an unchanged

* Read a section's target file, parse the section, validate the snapshot * tag (with recovery), and apply the edits in memory. Returns a * {@link

Dispose of any resources (e.g., LSP connection)

* Create an in-memory keybindings manager without file persistence.

* Execute a shell command and return stdout/stderr/code. * Supports timeout and abort signal.

Commits in `base..head`, oldest first.

Set the text content

Resolve the process `exited` promise and close stdout.

Snapshot every registered entry in insertion (id) order.

Force a redraw after async edits to the composer (live segment/preview inserts).

Schedule a repaint of the transcript.

Wipe all persisted state for this backend (slash `/memory clear`).

Get the current text content

Wait for the agent to finish streaming

* Returns the element at the specified index without removing it. * Supports negative indices (e.g., `-1` for the last element). * * @param inde
