- Remove 3 unused exported constants (TRIM_MESSAGES_TO, MAX_TERMINAL_COLS, MAX_TERMINAL_ROWS)
- Consolidate 8 direct util imports into barrel imports (./utils/index.js)
- Extract magic number 8191 to FILE_PEEK_BYTES constant in buffer-limits.ts
- Add explanatory comments to 9 undocumented .catch(() => {}) handlers

/**
|
||
* @fileoverview Core PTY session wrapper for Claude CLI interactions.
|
||
*
|
||
* Manages a PTY (pseudo-terminal) process running Claude CLI or OpenCode CLI.
|
||
* Three operation modes:
|
||
* 1. **One-shot** (`runPrompt`): Single prompt → JSON response
|
||
* 2. **Interactive** (`startInteractive`): Persistent interactive session
|
||
* 3. **Shell** (`startShell`): Plain bash shell for debugging
|
||
*
|
||
* Optionally wraps in a tmux session for persistence across disconnects.
|
||
* Tracks tokens, costs, background tasks, and auto-compact/clear.
|
||
*
|
||
* Key exports:
|
||
* - `Session` class — main entity, extends EventEmitter
|
||
* - `ClaudeMessage` interface — parsed JSON messages from Claude output
|
||
* - `SessionEvents` interface — typed event map
|
||
*
|
||
* Key methods: `runPrompt()`, `startInteractive()`, `startShell()`,
|
||
* `writeViaMux()`, `toState()`, `stop()`, `resize()`, `isIdle()`,
|
||
* `setAutoCompact()`, `findTaskDescriptionNear()`, `getTerminalBuffer()`
|
||
*
|
||
* @dependencies session-cli-builder (args/env), session-auto-ops (auto-compact/clear),
|
||
* ralph-tracker (todo/completion parsing), bash-tool-parser (tool invocation tracking),
|
||
* task-tracker (background tasks), mux-interface (tmux abstraction)
|
||
* @consumedby session-manager, web/server, respawn-controller
|
||
* @emits session:terminal, session:idle, session:working, session:completion, session:exit
|
||
*
|
||
* @module session
