- Added edit streaming fallback data to the edit render context and used it when no finalized patch text was available.
- Implemented hashline fallback rendering that strips envelope syntax, sanitizes text, and truncates output to a fixed number of lines with a streaming indicator.
- Updated tool execution to populate the fallback preview from the active edit strategy and added a renderer test for hashline envelope input while the diff is not yet computable.
- Added compact Lark grammar processing and applied it to OpenAI custom-format tools before conversion.
- Reworked atom mode into `---PATH` compact commands with new grammar, parser, and rm/mv file operations.
- Updated `hline`/`href`/`hrefr` helper behavior and hashline mismatch guidance using shared anchor state.
- Standardized path formatting with `formatPathRelativeToCwd` across LSP, prompts, and edit/search/write tools.
- Added benchmark run-path handling, including `.gitignore` runs mapping, absolute reports, and safer snapshot output.
- Added tests for compact grammar payloads, atom parsing/execution, renderer streaming, and path-list outputs.
- Added helper utilities in the edit renderer to parse partial JSON fragments and extract the `path` field.
- Used the extracted path as a fallback when resolving the edit target file, enabling partial streamed edit calls to show the path.
- Built and stored the render context before call rendering, and added a test covering partial JSON edit path rendering.
