non-exact patch matches warn and prefix/substring matches must preserve the discarded suffix; multi-entry edits stop at first failure and report applied vs not; ast-edit and file-mention snapshots use canonical realpath keys and re-record post-apply; notebook marker-shaped lines escaped on render; fuzzy matcher pre-normalizes once per seek; streaming preview caches text+tree per tick.
- Added tree-sitter `enclosing_block_boundaries` API with line range models.
- Added N-API `enclosingBlockBoundaries` bridge and exported JS declarations.
- Replaced matching-bracket context resolution with source-aware block context in read and diff flows.
- Passed source path through diff/read generators to surface native block boundary previews.
- Replaced all StringEnum(...) usages with z.enum([...]) across tools, examples, and tests.
- Removed StringEnum re-export from @oh-my-pi/pi-coding-agent public API.
- Condensed verbose tool parameter descriptions to minimal lowercase phrases.
- Renamed AuthCredentialStore to SqliteAuthCredentialStore at usage sites.
- Added canonical `pi.zod` schema API exports and removed TypeBox package exports/imports.
- Migrated Tool schema typing from TypeBox to shared `TSchema`/Zod flow with legacy TypeBox compatibility.
- Updated AI provider adapters and MCP/agent builders to convert tool params through `toolWireSchema()`.
- Reworked schema validation from AJV to Zod-safe parsing with `fromTypeBox`, `toolWireSchema`, and meta schema checks.
- EditTool now carries oldText/newText in per-file results for patch, replace, and multi-file aggregation paths
- Renderer updated to display diff content for all edit modes
- Enables downstream consumers (ACP event mapper, TUI) to render accurate diffs
- Added `.ipynb` detection and editable-cell conversion utilities, including merge/serialize helpers in `edit/notebook`.
- Rerouted hashline, patch, and replace edit flows, plus read/write paths, through notebook-aware helpers before persistence.
- Removed the dedicated `notebook` tool, its schema flags, renderer, and built-in registration/settings checks.
- Updated notebook read behavior, docs, and tests so `.ipynb` reads return editable `# %%` cells and edits reserialize to JSON.
- Required top-level `path` in edit requests, removed per-entry `path` fields, and updated docs/tests to match.
- Updated patch/hashline/atom streaming preview generation to return a single request-level path diff preview.
- Changed edit execution to route patch/replace/atom/hashline through single-path handlers sharing `path`.
- Added `scripts/analyze-edit-formats` Go CLI with reports to audit edit-tool usage from session JSONL logs.
- Added tracking of the last successful non-error yield tool call when a yield execution ends.
- Cleared the tracked yield ID and skipped post-turn maintenance when appropriate, including when the last assistant message was a successful yield.
- Standardized unchanged-result error messages in atom and replace edit modes.
- 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.
- Standardized missing-file read errors and now return `File not found: <path>` for absent edit targets.
- Centralized AI provider, usage, and OAuth helpers into shared modules to remove duplicated logic.
- Migrated OAuth/API-key login flows to shared factory helpers and removed inline prompt/token-exchange code.
- Reused shared tools and formatter utilities for discovery, stream tails, LSP batching, and source formatting.
- Consolidated repeated test helpers and fixtures into shared modules, replacing inline helper duplicates.
- Added multi-file edit payload support by requiring per-entry `edits` arrays across patch, hashline, replace, and chunk modes.
- Changed edit schemas and validators to move `path` (and `sel`->`path`) and op data into each edit entry.
- Changed edit execution flow to parse `file:selector` paths, run single-entry executors per file, and return grouped per-file results.
- Updated chunk diff rendering and test expectations to emit consistent anchor gutters with spaced pipes and `^` head-line markers.
- Reorganized edit tool from `patch/` to `edit/` directory with dedicated mode subdirectories (chunk, patch, hashline, replace).
- Replaced line-scoped edit operations with substring-based `find` parameter and added `replace_body` operation for preserving signatures.
- Added chunk focus modes (Expanded, Collapsed, Container) and focused rendering to display only touched chunks and adjacent siblings.
- Implemented notebook (ipynb) language support with virtual source conversion and cell-based chunk parsing.
- Enhanced chunk edit error messages with consistent checksum mismatch reporting and improved chunk selector auto-resolution.
- Extracted edit mode implementations into separate modules with improved helper functions and LSP integration for diagnostics.
