- Added annotation row detection to reject under-filled one-sided echoes on single-line replacement ranges.
- Raised default snapshot store path capacity from 30 to 256 to prevent early tags from aging out in wide sessions.
- Added comprehensive test suites verifying boundary repair for single-line annotations and snapshot LRU retention.
- Recover dangling range separators in hunk headers as single-line ranges instead of rejecting them.
- Ensure strict rejection is maintained when a dangling separator is followed by invalid tokens.
- Added `splitAddressableFileLines` to strip terminal newlines from line addressability without removing genuine blank lines.
- Updated coding-agent read tool context parsing to use addressable file lines.
- Prevented `formatNumberedLines` from appending a synthetic empty line when encountering a terminal newline.
- Added tests to ensure trailing newlines do not generate addressable blank lines.
- Added a post-apply syntax advisory warning when an edit breaks parsing on files that previously parsed cleanly.
- Implemented Rust-specific single-quote lexing in `computeDelimiterBalance` to correctly handle lifetimes and character literals.
- Added test suites covering rust lifetime delimiter counting and the post-apply parse advisory behavior.
- Refactored and condensed numerous system prompts, agent instructions, and tool documentation files across packages.
- Streamlined workflow rules, formatting constraints, and execution guidelines for improved clarity and brevity.
- Updated discovery rules, recommendation criteria, and syntax standards in prompt templates.
- Gate closer-spare boundary repairs on tree-sitter parse validation to prevent incorrect rewrites on unrecognized languages or pathless edits.
- Add a warning when a `+` body row matches a valid hunk header format to flag accidental literal text insertion.
- Add a tree-sitter syntax probe and parser veto to prevent syntax-unaware boundary repairs.
- Reject span pastes from empty named registers instead of deleting ranges.
- Reject duplicate top-level snapshot row line numbers during parsing.
- Export new syntax module symbols and add associated tests and changelog updates.
PUT ... @name with no matching capture no longer fails the patch: it
pastes nothing (a span target is still removed, i.e. it degrades to a
cut) and surfaces a warning naming the available registers. Anonymous
empty/ambiguous pastes still error. validateClipboardSequence now only
guards anonymous sequencing; applyEdits threads clipboard warnings into
ApplyResult.warnings.
- Implemented in-house, zero-dependency utility modules in `pi-utils` covering DOM manipulation, markdown parsing, templating, browser automation helpers, and terminal buffers.
- Migrated packages across the repository to consume the new internal utilities and `omptype` schema validators instead of external dependencies.
- Removed multiple external runtime and development dependencies including Zod, Marked, LRU cache, Turndown, and Puppeteer browser packages.
- Update Lark grammar to support the unified put, cut, move, and remove operations.
- Update documentation and prompts to reflect canonical inclusive range separators and named register rules.
- Replaced legacy `SWAP`, `INS`, and `PASTE` commands with unified `PUT` and `CUT` hunks across parser, grammar, tokenizer, and test suites.
- Added support for named registers and span paste operations in clipboard and block execution logic.
- Implemented indentation repair and enhanced gap locator formatting for improved patch resilience.
- Updated documentation, system prompts, and session analysis scripts to reflect the new syntax and header shapes.
