fixed retained-kernel restart and owner cleanup edge cases during recovery and disposal
tracked async user_python hooks during disposal-sensitive execution paths and hardened startup warmup tracking
strengthened cleanup and kernel lifecycle regressions to remove deadlocks, false positives, and timing flakes
scoped retained-kernel ownership to agent sessions and cleaned it up on session disposal
cleaned up warmed python owners on session startup failure and rejected new direct and tool-based python starts during disposal, including async hook, preflight, and warmup races
- Added parse_error_lines to ChunkTree and threaded parse-error line metadata through tree creation.
- Changed count_parse_errors to return (count, line numbers) and collect recursive parse-error positions.
- Added hashline edit input resolution so computeHashlineDiff accepts loc/content edits and throws on invalid payloads.
- Fixed apply_edits error rendering to fall back to full-tree context when edited chunks have downstream parse errors.
- Added a guard in AgentSession to detect prior user messages and skip eager todo injection after the initial user turn.
- Updated session tests to assert that only the first user message triggers eager todo enforcement while follow-up prompts do not.
- Documented the behavior change in the package changelog under Unreleased.
- Add /rename <title> slash command to set an explicit session name,
updating the session header, terminal tab title, and status line
- Add session_name status segment: displays the session name on the
right side of the status bar with a stable djb2-hash-derived accent
color unique to each name; shown in all presets when a name is set
- Add setSessionName source tracking ('user' vs 'auto'): auto-generated
titles are silently ignored once the user has explicitly set a name,
preventing the async title generation from overwriting a /rename
- Sanitize session names at storage time: strip C0/C1 control characters
(including ANSI ESC) via static #sanitizeName before storing, blocking
escape sequence injection into the TUI, terminal title, and session file
- Extend sanitizeStatusText to cover the full C0/C1 range as
defense-in-depth (superset of the previous \r\n\t-only strip)
- Use stored (sanitized) name for showStatus message and terminal title
in handleRenameCommand, not the raw user input
- Guard terminal title update in auto-title path via titleSource === 'auto'
so a user rename is never overwritten by a late-resolving LLM call
- Reset #titleSource in #newSessionSync so each new session starts fresh
- Thread source parameter through AgentSession.setSessionName wrapper;
extension API and RPC set_session_name treated as 'user' intent

Extension-registered models (via registerProvider) were stored directly in #models, which gets rebuilt from scratch on every refresh() call. The model selector triggers refresh("offline") on open, wiping all extension models from the list.
Store extension models as #runtimeModelOverlays that survive reloadStaticModels() and get merged during both #loadModels() and refreshRuntimeDiscoveries(). Persist extension API keys in a separate map restored after each clear cycle.
