Latest non-empty assistant text added at or after `start_index`.

Create the sandboxed Claude project dir under `$JCODE_HOME/external/...`.

Build a session with many short user/assistant turns so the preview overflows a small viewport (used to exercise the preview scrollbar + sticky header

Longest message prefix length `k` such that `base.message_boundaries[..k]` hashes match the first `k` messages of `messages`. Returns `0` when nothing

Try to fix common LLM mistakes in batch tool_calls: - Parameters placed at the same level as "tool" instead of nested under "parameters" - "name" used

Open a file/URL with the system opener, unless suppressed. Every TUI-initiated `open::that_detached` must go through here: it honors NO_BROWSER/JCODE

Record an intentional harness-side cache invalidation. Call this from the code that performs a prompt-affecting change, at the moment it happens. `de

Record a permission decision by directly manipulating the queue/history JSON files. Used by the IMAP reply poller which doesn't have access to the liv

Snapshot the active-pid registry + streaming markers into the picker.

Register a factory for an externally-implemented provider runtime. Call this from the binary's composition root before any provider selection runs. R

Record an image payload so [`materialize_visible`] can decode it on demand. Skipped entirely for images that are already materialized: their decoded

Drop a session's background-tool signal registration.

Render the inline swarm gallery for `members` into `width`-bounded lines. `max_height` is the total height budget for the band (including the header)

Render the swarm dock: a narrow, vertical agent list sized for the info-widget margins (~20-38 inner columns). Layout (all lines bounded to `width`,

Render the inline todo-list card (`role == "todos"`). New payloads contain both todo items and goal assessments; the legacy item-array shape remains s

Resolve a channel/launcher binary path to the file that actually runs. Release archives install a tiny `jcode` wrapper script alongside the real `jco

Write the jcode auth file (multi-account format).

Scroll the preview up by `amount` lines. Returns whether the offset moved.

Record a terminal focus-state change (from crossterm FocusGained/FocusLost). Returns true when a redraw is warranted (focus regained, so we repaint at

Record an exact, freshly computed count as the trusted value.

Set the value of an element (background typing into a field).

Begin the onboarding simulator at the first screen.

Provider-agnostic streaming idle timeout: max seconds to wait between streamed chunks/events before treating the connection as dead. Resolved from `[p

Map swarm plan items into the todo-widget model so the persistent info widget renders live plan state (this is the durable surface backing the transie

Tier 1 score for a path, 0..=100. Penalize keystrokes, decisions, and extra screens; reward reaching a ready state. The weights are deliberately simpl

Tier 3 score for one screen, 0..=100. Reading load dominates; consistency and an escape hatch are smaller bonuses.

Show the session todo list as an inline card in the chat transcript, or dismiss it when the card is already the trailing message.

Update launcher path to point at the current channel binary.
