Directory holding one file per active session ID (`~/.jcode/active_pids`).

Advance the `shared-server` channel to `version`, but only when it is currently tracking `stable` (see [`shared_server_tracks_stable`]). Returns `Ok(t

Set alignment on a line only if it doesn't already have one set. This allows markdown rendering to mark code blocks as left-aligned while other conten

Re-segment the trailing `tail_fade_chars` characters into per-character runs with a rising alpha ramp toward the end of the text. This is the streamin

Extract plain text from a TestBackend buffer after rendering.

Get the prompt cache TTL in seconds for a given provider/model pair. This is provider cache-retention policy: it depends only on provider families (a

Canonical lowercase key: trimmed, ASCII-lowercased, `[1m]` stripped. Use this whenever model ids are compared or used as map keys across subsystem bo

Perform BFS cascade retrieval starting from seed memories Starting from embedding search hits (seeds), traverse through the graph via tags and other

Check if background compaction is done and apply it, updating rolling token-estimate state from the provided full message list.

Check all threads in a process group (for cases where a child is the one reading)

Inspect `messages` and, if any `ContentBlock::Image` exceeds the per-image edge limit implied by the total image count, or the per-image base64 byte c

Clear conversation history

Clear all runtime model unavailability markers.

Clear image state (call on app exit to free memory)

In `current` reasoning display mode, reasoning is shown live but collapsed once the assistant commits a message or runs a tool. Strip any reasoning-ma

Number of user prompts hidden before the first visible message because of compacted-history truncation. Used to keep prompt numbers absolute.

Connect to a socket path. Do not unlink the path on connection-refused here. A client-side cleanup can strand a live daemon behind an unlinked Unix s

Create a headless test session.

Debug socket path for testing/introspection Derived from main socket path

Destroy a test session.

Detect if an active session likely crashed (process no longer running) Returns true if status was updated.

Detect a KV/prompt-cache problem that is reliable enough to surface in the UI. This intentionally does **not** warn merely because a cache-hit metric

A prettier label for user-facing messages, e.g. `Cmd+Shift+K`.

Returns a display-safe snapshot that avoids showing pre-reset usage after a window rolled over.

Effective prompt size to use as the denominator for cache-hit ratios. Providers report `input_tokens` differently: - Anthropic/Claude (split accounti

Best-effort current token count using the caller's messages.

Generate embedding for text using the global embedder. Results are cached in an LRU so repeated queries for the same text return instantly.

Ensure context fits before an API call. Starts background compaction if above 80%. If context is critically full (>=95%), also performs an immediate

Generate and set embedding if not already present. Returns true if embedding was generated, false if already exists or failed.

Switch from the summary screen to the per-login checkbox list, with the cursor on the first login row.

Extract text from message content blocks.

Resolver that pretends every path under one of `roots` belongs to that root, mimicking git-root folding without touching disk.

Encode a length-delimited (wire type 2) protobuf field.

Apply a completed auth-driven catalog refresh to an already-open picker. Login/import can finish while `/model` is visible, so merely invalidating its
