- Removed `pi-natives` chunk language classifier modules and all core chunk subsystems (kind, state, render, edit, resolve).
- Removed chunk-mode CLI/read/edit entrypoints, including `read` command and chunk mode registration/prompt tooling.
- Removed chunk selectors from `read` and `grep` tools, switching behavior to raw/L-range handling.
- Fixed poll wait parsing to keep defaulting to `30s` when the provided value is empty.
- Extended optional git metadata checks to treat ENFILE and EMFILE like missing paths.
- Updated sync and async helper functions to return null for those filesystem errors instead of throwing.
- Documented the status-line branch-rendering fallback for ENFILE/EMFILE failures in the changelog.
- Enabled Biome VCS settings and expanded fix scripts with new `fix:all` and `fix:tools:all` commands.
- Updated `fix:ts` and `fix:tools` to separate changed-only checks from full-run formatting and generation tasks.
- Simplified edit-benchmark variant parsing by removing hardcoded validation logic, and removed deprecated flags from `run-rs-task.ts`.
- Added raw read output propagation so read/archive commands bypass anchors, line numbers, and chunk formatting.
- Fixed atom/hashline editing by tightening hashline prefixes and applying grouped anchor edits in stable order.
- Hardened chunk parsing and path handling by using `bigram_end` checks and resolving edit paths via shared `args.path` fallback.
- Updated path-related behavior for chunk, replace, patch, and hashline previews to honor optional edit paths.
- Removed mode-level param validators and replaced them with runtime handling, then removed obsolete validation tests.
- Added `atom` edit mode to `EditTool` with single-point hashline-style dispatch and `executeAtomSingle`.
- Added `AtomToolEdit`/`AtomParams` schema and `atom` prompt docs to require one op per edit entry.
- Changed `EditTool` entry processing to inherit per-entry `path` from a top-level request `path` fallback.
- Added top-level `path` defaults to patch and replace schemas and now reject missing entry paths.
- Added an `atom` streaming strategy and registered it in `EDIT_MODE_STRATEGIES` for live mode support.
- Enabled hashline read anchors for `atom` mode via `file-display-mode.ts` path-display logic.
- Added `atom` unit tests covering schema checks, anchor conflicts, and hash mismatch diagnostics.
- Added built-in model entries for gpt-5.5 and gpt-image-2, including updated context windows, token limits, and pricing.
- Updated generated-model policy application to set or clear applyPatchToolType based on inferred GPT-5 freeform rules.

- Added tests for GPT-5 freeform policy inference and Spark edit-mode default, variant, and strict-mode behavior.
Slots a new "apply_patch" variant alongside the existing edit modes
(replace, patch, hashline, chunk, vim). The mode accepts a single input
string containing a Codex *** Begin Patch / *** End Patch envelope,
parses it with a new lenient parser (heredoc-tolerant), and fans each
file-op out to the existing executePatchSingle so LSP writethrough,
plan-mode guards, fs-cache invalidation and diagnostics are shared
with the patch mode.
Exposes both tool shapes from the spec: the JSON function-tool variant
(§1.2, {input: string}) and the OpenAI custom-tool / Lark-grammar
"freeform" variant (§1.1, raw patch string). The edit tool advertises
a Lark grammar via customFormat and a wire name via customWireName;
openai-responses emits it as a grammar-constrained custom tool when a
model opts in with applyPatchToolType: "freeform" in models.json.
custom_tool_call / custom_tool_call_output are plumbed end-to-end
through the shared responses code (emission, streaming, history
replay), and the agent-loop dispatcher matches tool calls by either
name or customWireName so returned calls route correctly.
Also threads preview/diff rendering for apply_patch through the TUI
(tool-execution + edit renderer) so streaming patches show per-file
diffs like the other edit modes.
Default edit mode is unchanged (hashline); opt in via edit.mode or
PI_EDIT_VARIANT=apply_patch.
- Updated todo start handling to set the requested task to in_progress while demoting all other in_progress tasks to pending.
- Added task note rendering in summary output by prefixing each note line with "Note:".
- Set GIT_OPTIONAL_LOCKS to 0 in git execution options and added tests for out-of-order start jumps and note summaries.
ollama-chat was missing from buildNamedToolChoice, causing forced tool
calls (e.g. eager todo enforcement, submit-result) to be skipped for
Ollama Cloud models. Ollama supports tool_choice: "required" but not
named function forcing, so it maps to "required" alongside the
Google APIs.
- Removed the standalone vim tool and normalized built-in/requested tooling to edit.
- Updated session and SDK tool activation to dedupe lowercase names and track edit state via the edit key.
- Added vim-mode argument detection and delegated edit rendering/execution into Vim handlers under edit.
- Updated Vim step handling to auto-reorder numeric-positioned commands, including cc/C/S/s/i/I/A cases.
- Renamed prompt/changelog text and test expectations to reflect edit-only tool naming and usage.
- Added `vim` as a supported edit mode and resolved mode-specific active tool names.
- Migrated chunk-edit requests from legacy `op`/`content` to `path` plus `write`, `replace`, and `insert`.
- Replaced chunk-edit internals with `put`/`replace`/`delete` operations and ID-based selection.
- Updated chunk prompts/output docs to document ID-based selectors and `write: null` deletions.
- Switched chunk and grep render output to `@`/dash-style anchors and updated file-count behavior for multi-file edits.
- Updated multi-file result rendering with distinct file counting and pending-file progress indicator.
- Refreshed chunk-mode and chunk-tree tests for the new contract and anchor style.
- Propagated session title source through terminal-title update calls so auto and user names are handled consistently across controllers.
- Suppressed auto-generated names in status-line segments and completion messages by falling back to cwd-based titles.
- Updated title formatter tests to verify auto-generated and user-specified session titles produce different terminal labels.
- Added `/rename <title>` slash command to set explicit session names and update header/tab titles.
- Added `session_name` status segment with hash-derived accent color for session titles.
- Fixed shell execution failure sanitization to preserve all `execResult` fields after redacting stderr.
- Fixed tool execution completion output to pass original `toolResult` text instead of sanitized `content`.
- 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
