- Added a dedicated @oh-my-pi/hashline package with parser, patcher, filesystem, snapshots, and release metadata.
- Migrated coding-agent hashline and stream entrypoints to @oh-my-pi/hashline and removed old hashline module exports.
- Changed multi-section hashline execution to validate section hashes and flush diagnostics only at the final commit.
- Added session fileSnapshotStore support and rewired edit/read/search/write tools to use it instead of fileReadCache.
- Added `unfoldUntilLines`/`unfoldLimitLines` options to progressively reveal nested elidable spans breadth-first instead of collapsing everything behind the outermost elision.
- Added `minTotalLines` setting to skip summarization for short files, returning verbatim content instead.
- Added `:` selector support to `search` paths for constraining matches to specific line ranges.

- Assigned read/write/exec `approval` and approval-detail prompts across built-in, custom, extension, and MCP tools.
- Replaced per-line hash anchors with file-level hash validation in hashline format, changing anchor syntax from LINE+HASH to bare LINE numbers.
- Simplified hashline line separator from pipe (|) to colon (:) and replaced replace operator (->) with colon, added delete operator (!) for explicit line deletion.
- Implemented file-read snapshot caching with multi-snapshot ring buffer per path and file-hash-based recovery to detect and recover from stale edits.
- Refactored hashline grammar, parser, and execution to support file-level hash binding, anchor-scoped validation, and structural bracket warnings for delete operations.
- Updated documentation and test fixtures to reflect new hashline syntax with file hashes, colon separators, and delete operator throughout.
Adds a focused redaction utility that targets well-known token shapes
(AWS, GitHub PATs/tokens, Slack, OpenAI-style sk-, JWT) plus a
key/value heuristic for env-style lines whose key contains SECRET /
TOKEN / PASSWORD / API_KEY / PRIVATE_KEY, plus Bearer/Basic Authorization
header values. Replacements are tagged `#REDACTED:<hint>#` so callers
can tell why each value was scrubbed.
Wired into read, search and ssh tool outputs. Each call site appends a
`[redacted N secret-like values]` footer when at least one value was
scrubbed so the model knows the output was modified.
Gated behind a new `tools.redactSecrets` boolean setting (default true).
Sandboxed tests that intentionally surface secret-shaped fixtures can
disable it via Settings.isolated({ "tools.redactSecrets": false }).
The read renderer was emitting `LINE+HASH|content` for lines whose
content had been column-truncated for display, but `computeLineHash`
is content-only and recomputes against the disk line. The model copied
the displayed anchor, edit rejected it as mismatched, even though the
underlying file had not changed.
formatTextWithMode now accepts an optional truncatedLines set; in
hashLines mode those lines emit as `LINE|content` (no hash) so the
verifier never tries to recompute against truncated text. Multi-range
and single-range read paths both populate the set when truncateLine
flips wasTruncated.
The ignoreResultLimits flag now gates only the byte-budget tail-truncate,
never the explicit line window. Reads of internal URLs (skill, local,
memory) with a line range previously returned the tail of the file
instead of the requested window for files larger than the byte budget.

- Updated AI provider adapters and MCP/agent builders to convert tool params through `toolWireSchema()`.
- Reworked schema validation from AJV to Zod-safe parsing with `fromTypeBox`, `toolWireSchema`, and meta schema checks.
- Added stripOutputNotice to output-meta to remove appended truncation notices when output metadata is available.
- Updated bash, eval, browser, read, and ssh renderers to strip the notice before display so the styled warning line is not duplicated.
- Left fallback behavior unchanged so outputs without a notice continue through unchanged.
- Updated shell minimizer line truncation to append `...[+N]` with the count of dropped Unicode scalars when truncation occurs.
- Updated read summary rendering to track `elidedLines`, include them in tool details, and append a recovery footer for `:raw` or line-range access whenever elided spans are present.
- Updated read-tool prompts/docs/tests to cover the new elision-footers and recovery guidance.
