- 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.

- Added `atom` unit tests covering schema checks, anchor conflicts, and hash mismatch diagnostics.
- Aligned hashline and chunk token handling to `HASHLINE_BIGRAMS` in `computeLineHash` and parsing regexes.
- Removed hashline file-level `move`/`delete` options from schemas and execution so edits are in-place updates only.
- Hardened hashline prefix parsing to reject non-bigram IDs, preventing false stripping of `#` comment lines.
- Updated `read()`/prompt wording so raw reads skip prefixes and examples now show anchors like `123#th`.
- Updated hashline chunk tests for new `HASHLINE_BIGRAMS` IDs and replaced stale hash constants.
- Prevented template compile failures from `}}}` sequences by normalizing closing braces before `handlebars.compile`.
- Updated Unreleased `CHANGELOG.md` to describe current hashline/edit/path behavior changes.
- Standardized tool prompt example formatting by replacing `<example>` blocks with unified `<examples>` sections.
- Add explicit validation rejecting write:"" with the expected error message in normalizeChunkEditOperations.
- Update spark context-promotion tests (it_1, it_2, concurrent it_5) to expect promotion to gpt-5.5 (the new chain target on openai-codex), since spark variants now promote to gpt-5.5 rather than the base codex model.
- Removed `read: true` from chunk edit schema and validation logic, including mixed read/write checks and read-only execution paths.
- Updated chunk edit normalization to treat chunk operations as mutating and removed unused read-result handling.
- Updated prompts and changelog guidance to require `open` for inspection and document that chunk edits use only `write`, `insert`, or `delete`.
- Added markdown `Row` chunk support by introducing `ChunkKind::Row`, mapping it to tag `"row"`, and emitting row chunks for table rows.
- Updated Go chunk parsing to support method signatures (`func (recv) Name`), prefer method parsing in signatures, and adjust root rules to classify package/import chunks correctly.
- Changed chunk-edit behavior to add read-only `read:true`, replace `write:null` deletes with explicit `delete`, and require one explicit action per entry.
- Added safer chunk-edit execution with region matching, replacement reindentation, table-row append handling, and stricter warnings/errors for boundary and invalid operations.
- Fixed chunk edits to reject invalid `^`/`~` operations on code-leaf chunks.
- Fixed multiline replacement behavior to preserve literal insertion text and adjust multiline match starts.
- Fixed unsupported-region handling to warn, fall back to whole-chunk edits, and clear invalid region targets.
- Documented chunk-edit behavior for raw whitespace, parser boundaries, `sel="?"` refresh, markdown spacing, and streaming headers.
- Updated open-chunk prompt docs to describe URL handling, document/image extraction, and directory/archive traversal.
- Expanded selector behavior documentation for full-file, chunk, line-range, and raw reads, including the one-line `L20-L20` format.
- Updated the generic open prompt table to clarify `L50` shorthand as a range-to-EOF read and add single-line range support.
- 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.
- Canonicalized file and CLI defaults from `read` to `open` across tool registration and prompts.
- Added `resolveToolAlias()` and applied alias-normalized tool selection so legacy `read` maps to `open`.
- Updated runtime, UI, and export layers to treat `open` as first-class while preserving `read` compatibility.
- Renamed read prompt docs to `open.md`/`open-chunk.md` and refreshed system guidance to recommend `open`.
- Updated tool-related tests and expectations from `read` to `open` (including test fixtures and aliases).
- Updated the LSP prompt to require symbol-aware operations to use `lsp` when a language server is available.
- Added explicit warnings against cross-file text-based renames, recommending `lsp` rename and code actions for server-known fixes.
- Updated `chunkReadPathSeparatorIndex` to detect URL schemes and split at the final selector colon only after the URL path.
- Added tests for `parseChunkEditPath` and `parseChunkReadPath` covering local plan URLs with selectors and scheme-only URLs.
- Updated browser tool guidance to prefer `read` for static web content and use browser automation only when JavaScript, authentication, or interaction is required.
- Expanded the `read` tool documentation to include broader document and URL formats and to call out reader-mode text extraction.
- Strengthened instructions by requiring `read` for file/directory/archive/URL reads and discouraging browser/puppeteer for static web content.
- Updated minimizer mode selection so `Compound`, `Piped`, and `Unsupported` plans now skip minimization.
- Removed `MarkedCommands` mode and marker-stripping paths from shell minimizer and buffering flow.
- Updated minimizer tests and changelog to document compound/piped commands bypassing minimization.
- Deleted marker metadata and helper infrastructure (`markers.rs` types/helpers) and related imports.
- Parallelized `collectSessionsFromFiles` via strided workers sized by file count and CPU parallelism, reducing large-list latency.
- Read only a fixed 1024-byte prefix per session file in `collectSessionFromFile`, avoiding full-file scans.
- Added partial-prefix fallbacks to extract session title and first user message when JSONL parsing is incomplete.
- Added cached retrieval of all sessions in AcpAgent with a 60s TTL, in-flight deduplication, and cache invalidation when creating a session.

- Added `onMinimizedSave` and `saveBashOriginalArtifact` to persist full bash-original output artifacts.
- Expanded public exports and marker hooks so external command launch metadata can be controlled by consumers.

When the Codex Responses API synthesizes an answer without emitting
url_citation annotations, previously-empty sources made cited results
look ungrounded. Add:
- tool_choice: { type: "web_search" } so Codex must call the tool
- markdown-link + bare-URL extraction from the answer as a fallback
that only runs when no structured citations were returned
The model-resolution path is unchanged; getBundledModels already
returns a usable Codex catalog on main.
Closes#724
