- Added auto-rebasing for stale atom and hashline anchors within ±2 lines, with warning diagnostics. - Removed atom range-locator support and dropped `between` ops, updating docs/tests for `sub` over `set` nudges. - Changed no-op handling to track unchanged hashline edits and emit contextual hints for unchanged ranges. - Expanded Anthropic strict error handling to retry on schema-too-complex and compiled-grammar-too-large errors. - Added anchor-retargeting warning checks and updated edit tests to expect locator and range-locator rejections. - Updated python tool-call fixtures by adding `title` to executed-cell payloads and adjusting related test expectations.
