- Extended continuation preprocessing to allow backslash lines after single-line replace operations (including legacy `@` and `|` forms) while preserving the active-replacement check.
- Added tests and prompt documentation for single-line continuation cases and for rejection of backslash-like text outside an active replacement.
- Added `with_text` to keep minimized output byte counters consistent when replacing output text.
- Wrapped successful pipeline and overlay minimizer results with a post-step that emits `OK\n` when the transform empties output on success.
- Added tests to confirm successful empty-output minimization becomes `OK\n` and failures keep empty output.
- Added atom edit support for Lid ranges, before-anchor inserts, and no-op Lid=TEXT success handling.
- Expanded hashline recovery to scan shifted hashes, match unique alternates, and emit ±5 anchor-shift hints.
- Added edit failure categorization with per-category counts, percentages, and detailed report lines.
- Added regression coverage for shifted-hash recovery, range continuation, cursor shorthand, and split-file atom ops.
- Resolved recipe operations now return a command plus optional working directory, and the shell tool path forwards both values when executing.

- Synchronized prompts, tool schema rendering, and regression tests to document and verify `#N` occurrence selection instead of a standalone occurrence field.
- Updated the tool configuration key and labels from runCommand to recipe, including its settings UI schema.
- Renamed the run_command tool implementation, prompts, and test wiring to recipe and updated tool registry and renderer registrations.
- Adjusted auto-included tool behavior and availability checks to use the recipe name and recipe.enabled setting.
- Reversed atom mode parsing of cursor anchors so "^" now resolved to BOF and "$" to EOF.
- Updated the atom command documentation and examples to reflect the corrected BOF/EOF markers.
- Adjusted parser tests to expect prepend via "^" and append via "$" with corresponding cursor kinds.
- Root package tasks were set to use `namespaced: false` when collected.

- Added tests covering OAuth defaults and opt-outs for Anthropic and non-Anthropic custom providers.
- Atom edit application stopped throwing when a `-Lid|OLD` delete anchor's OLD payload mismatched the current line.
- Delete hunks now ignore the OLD payload and rely on Lid hash anchoring for validation and rebasing.
- Atom edge-case tests were updated to verify mismatched OLD payloads are now accepted when hashes still match.
- Added loop-mode command handling in interactive mode, including enable/disable toggling, repeated auto-submission scheduling, and Escape-based cancellation.
- Propagated loop mode state to the status line via a renamed `mode` segment that now renders plan or loop status, and updated presets/theme assets for the new loop icon.

- update BUG 3 regex to match "splice locator" warning text
- drop the "rejects mixing splice_block with other anchor edits" test;
splice_block intentionally coexists with other anchor edits
- Removed the `F` sed flag and `literal` field, keeping only `pat`, `rep`, and `g`, and dropped the obsolete `F` test.
- Updated sed parsing, serialization, and error text to remove `splice_block` exclusivity and explain regex escaping.
- Reworked atom prompt format to `<ops>/<splice>/<sed>`, with shared `{path, edits}` calls and strict one-loc/one-verb rules.
- Updated docs (`read.md` and `CHANGELOG.md`) to remove `F:true` anti-patterns and add current `line+hash` and sed behavior guidance.
- Simplified diagnostic grouping output in the LSP utility to use plain `## file` headers.
- Adjusted AstEdit, AstGrep, and Grep tools to emit file headings without the `└─` tree prefix.
- Removed the GrepTool context legend text and its related guard variable from output construction.
- Replaced `AgentTool` `nointent` and `deriveIntent` with a unified `intent` option that supports `omit`, `optional`, `require`, or a callback function.
- Updated agent tool schema injection and execution paths to inject `_i` as required/optional/omitted and to derive intent through the new `intent` callback.
- Aligned atom-edit tests with the updated default sed behavior (`g` now off by default and explicit `g: true` for global replacement).
- Replaced `atom.sed` string syntax with `{pat,rep,g?,F?,i?}` objects in schema, prompts, and tests.
- Changed sed validation defaults so `pat` is regex, `g` defaults to global replacement, and `F:true` forces literal matching.
- Fixed `sed` edge cases by allowing sequential same-anchor edits, handling zero-length matches, and preserving chaining.
- Updated native build flow to local `--profile` defaults, refactored enum generation, and switched totals to `total_ms`.
Drop three pieces of well-intentioned-but-fragile string mangling that
were quietly mutating model edit content:
- `maybeAutocorrectEscapedTabIndentation` in both hashline and atom edit
modes (plus the `PI_HASHLINE_AUTOCORRECT_ESCAPED_TABS` env toggle and
`isEscapedTabAutocorrectEnabled` helper). Literal `\\t` in edit content
is now preserved verbatim.
- `maybeWarnSuspiciousUnicodeEscapePlaceholder` and the
`runHashlinePreflightSanitizers` wrapper. The warning was misleading:
it flagged `\\uDDDD` as suspicious without distinguishing intentional
literal text from a likely-malformed escape, and it was the only
remaining caller.
- The hand-rolled JSON-unescape fallback in
`decodePartialJsonStringFragment` (renderer.ts). The fallback used
`String.fromCharCode` (mishandling lone surrogates) and only covered a
subset of JSON escapes, so the same fragment decoded one way mid-stream
and a different way after `JSON.parse` succeeded. Now we trim a
trailing partial `\\u`/odd-backslash escape and surface the raw
fragment if `JSON.parse` still fails.
- Added a guard in applySedToLine that probes matches and rejects sed patterns that match empty strings.
- Updated atom edit error handling to label invalid sed expressions as rejected rather than failed to compile.
- Adjusted sed tests to expect the new rejection wording and added coverage for zero-length pattern `s/()/X/`.
- Updated `read` selector parsing for file and URL reads to accept optional leading `L` and `+` count-style ranges.
- Adjusted truncation notices and schema/help text to emit and suggest `sel` offsets without the `L` prefix, including continuation and suggestion messages.
- Updated hashline/output parsing and related tests to recognize the new `sel` formatting in truncation notices.
- Renamed atom tool schema fields and internal `AtomEdit` operation from `set` to `splice` in edit parsing and application.
- Adjusted resolver and conflict checks to use `splice` semantics, including file-loc rejection, blank-line deletion handling, and sed precedence.
- Updated atom edit documentation and tests to describe and verify the new `splice`-based API.
- Updated `formatMatchLine` to emit `*` for matched lines, a leading space for context, and a `|` anchor/content separator.
- Revised grep/hashline mismatch messages and prompts to describe the new marker and separator format.
- Aligned affected atom and hashline tests with the updated match-line prefixes and separators.
- Added `AgentRegistry` singleton with session registration/unregistration and IRC routing metadata for peer lookups.
- Added IRC messaging prompts and tooling with `irc.enabled` setting, `list/send` tool paths, and peer roster rendering.
- Changed `/btw` to session-side `runEphemeralTurn`, added background IRC exchange flushing, and fixed empty-input checks.
- Added unit tests for IRC tool and BtwController ephemeral behavior, including disabled, busy, not-found, and abort cases.
- Added a unified `job` prompt and removed `poll` and `cancel-job` prompts, documenting merged async actions.
- Renamed `PollTool` to `JobTool` and replaced `poll`/`cancel_job` tool exports with a unified `job` tool.
- Expanded `JobTool` schema to accept `poll` and `cancel` IDs, adding cancel-first execution for cancel-only requests.
- Consolidated poll/cancel rendering in `renderJob`, mapping `await`, `poll`, and `cancel_job` keys to the unified job renderer with action badges.
- Updated bash/task prompts and tests to use `job` for polling and cancellation flows, including JobTool auto-background checks.
- Updated atom edit location parsing to treat "$" as a file-wide target for prepend, append, and sed, and rejected "^" as a supported locator.
- Added a new sed_file operation that runs line-wise substitutions across the full file, preserving ordering and trailing-newline semantics while failing when no lines match.
- Removed per-entry path overrides from atom resolution and made read selector parsing return "none" for unrecognized selectors to defer handling to specialized readers.
- Removed `pi-natives` chunk language classifier modules and all core chunk subsystems (kind, state, render, edit, resolve).
- Removed chunk-mode CLI/read/edit entrypoints, including `read` command and chunk mode registration/prompt tooling.
- Removed chunk selectors from `read` and `grep` tools, switching behavior to raw/L-range handling.
- Fixed poll wait parsing to keep defaulting to `30s` when the provided value is empty.
- Session metadata now stores on-disk size bytes, populated from file stats when collecting sessions.
- The session selector metadata line now renders file size using formatBytes instead of message counts.
- Session test fixtures were updated with the new size property so they match the revised SessionInfo shape.
