* Initial plan
* Add adaptive reconciliation, concrete remediation steps, and xxHash32 JS fallback
- auto.ts: final reconciliation pass before halting on loop detection
(runs skipExecuteTask to write blocker artifacts and advance pipeline)
- auto.ts: adaptive retry on prevCount>=2: write stub summary when still
missing after two agent sessions, so the agent has a recovery context
- auto.ts: buildLoopRemediationSteps() helper with concrete manual steps
when automatic reconciliation cannot resolve the unit
- xxhash/index.ts: pure-JS xxHash32 fallback when native addon does not
export xxHash32 (prevents 'native.xxHash32 is not a function' crash)
- idle-recovery.test.ts: tests for buildLoopRemediationSteps and loop-recovery
path in skipExecuteTask
Co-authored-by: glittercowboy <186001655+glittercowboy@users.noreply.github.com>
* Address code review feedback
- xxhash/index.ts: extract accumulate() helper to remove duplicate lane
processing lines in the 16-byte loop
- auto.ts: replace magic number 2 with named constant STUB_RECOVERY_THRESHOLD
- idle-recovery.test.ts: add comment explaining the 3 (== MAX_UNIT_DISPATCHES)
used in the loop-recovery test
Co-authored-by: glittercowboy <186001655+glittercowboy@users.noreply.github.com>
* Address PR review: verify post-state, fix stub wording, fix checkbox syntax, add fallback test
- auto.ts (MAX branch): check verifyExpectedArtifact() after skipExecuteTask()
before advancing; annotate both conditions explaining what each validates
- auto.ts (self-repair branch): guard advance with verifyExpectedArtifact() so
regex mismatches in the slice plan don't silently re-dispatch
- auto.ts (stub-recovery): write stub summary directly with "PARTIAL RECOVERY"
wording instead of using skipExecuteTask (which would claim "exhausted N attempts")
- auto.ts (remediation): fix checkbox example to "- [x] **${tid}:" (no trailing **)
- xxhash/index.ts: export xxHash32Fallback so CI can test JS path independently
- native/src/index.ts: re-export xxHash32Fallback
- xxhash.test.mjs: add "xxHash32Fallback (pure-JS path)" describe block that
validates the JS implementation against the reference on all test cases

* feat: add native Rust output truncation module
Line-boundary-aware truncation for tool outputs (bash, grep, file reads),
replacing JS byte-counting with native Rust via napi-rs. Supports head,
tail, and both modes. Counts by UTF-8 bytes, respects line boundaries,
uses memchr for fast newline scanning.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: remove unsafe blocks and fix truncation message byte counts
Replace unsafe from_utf8_unchecked with safe from_utf8().expect() —
the invariant (splitting at newline boundaries) is sound but the perf
difference is negligible, so no reason to use unsafe.
Fix truncateOutput messages that reported the byte budget as "bytes
truncated" instead of the actual number of bytes removed.

* feat: replace pure-JS xxHash32 with native Rust implementation via napi
The hashline edit tool calls xxHash32 on every line of every file read/edit.
Moving this to a native Rust implementation (xxhash-rust crate) eliminates
JS overhead for this hot path. Hash output is identical -- verified by tests
comparing native vs JS reference across 11 input vectors including empty
strings, short/long inputs, unicode, and seeded variants.

Replaces the multi-pass JS pipeline (TextDecoder → stripAnsi → sanitizeBinaryOutput)
in bash-executor.ts with a single native Rust call that handles UTF-8 decoding,
ANSI stripping, binary sanitization, and CR removal in one pass.
Key features:
- StreamState tracks incomplete UTF-8 and ANSI sequences across chunk boundaries
- Standalone stripAnsiNative() and sanitizeBinaryOutputNative() for use elsewhere
- Comprehensive test coverage for split multibyte, split ANSI, binary data

* feat: add native Rust streaming JSON parser for LLM tool call argument parsing
Replaces the JS partial-json library with a Rust implementation exposed via napi-rs.
The parser handles incomplete JSON from streaming deltas by closing unclosed strings,
objects, arrays, removing trailing commas, and completing truncated literals.

* fix: handle truncated numbers and remove dead partial-json dependency
Adds truncated number recovery (e.g. `{"key": 12`, `{"key": 3.`, `{"key": 1e`)
to the Rust streaming JSON parser, and removes the now-unused `partial-json`
npm dependency from pi-ai.

Rename all platform packages from @gsd/engine-* to @gsd-build/engine-*
to match the npm org. Remove the darwin-arm64 binary from git and
native/addon from files — production binaries come exclusively from
CI-published platform packages.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add the esbuild/swc pattern for distributing platform-specific native
binaries via npm optional dependencies. Each supported platform gets its
own @gsd/engine-{platform} package containing just the .node binary.
- 5 platform package stubs (darwin-arm64, darwin-x64, linux-x64-gnu,
linux-arm64-gnu, win32-x64-msvc) with os/cpu filters
- Rewritten native loader: tries npm package first, then local build
- Version sync script keeps platform packages in lock-step with root
- GitHub Actions workflow for cross-platform build + publish on tag push

The native .node binary was excluded from npm pack due to native/.gitignore
ignoring addon/. Add native/.npmignore (overrides .gitignore for npm) and
include native/addon in the files whitelist. Also improve the error message
in the native loader to list supported platforms and link to issues.

Implements a Rust napi-rs module that parses YAML-like frontmatter,
markdown sections, and roadmap structures from .gsd/ files. Provides
parseFrontmatter, extractSection, extractAllSections, batchParseGsdFiles,
and parseRoadmapFile functions exposed via @gsd/native. The JS parsers
in files.ts fall back transparently when the native module is unavailable.

Move the edit tool's hot-path diffing operations from JS to native Rust:
- `normalizeForFuzzyMatch`: single-pass Unicode normalization (smart quotes,
dashes, special spaces, trailing whitespace)
- `fuzzyFindText`: exact-then-fuzzy substring search with UTF-16 index
conversion for JS compatibility
- `generateDiff`: unified diff generation using the `similar` crate
(Myers' algorithm with optimizations)
The Rust module at `native/crates/engine/src/diff.rs` exposes three napi
functions. The TypeScript wrapper at `packages/native/src/diff/` follows
the existing module pattern. `edit-diff.ts` now delegates to native
implementations while keeping line-ending handling and file I/O in JS.
18 tests covering normalization, fuzzy matching (including UTF-16 index
correctness with emoji/surrogate pairs), and diff generation.

@gsd/native shipped raw .ts files in node_modules, which Node.js
refuses to import (ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING on
Node 22/24, ERR_UNKNOWN_FILE_EXTENSION on Node 20). Add tsc build
step, point exports at dist/, and add to bundleDependencies.
Closes#248

TTSR's checkDelta() runs O(rules x conditions) regex evaluations per
streaming token — the hottest path in GSD. This adds a Rust native
module that compiles all condition patterns into a single RegexSet,
testing them in one DFA pass instead of sequential JS RegExp iteration.
The TtsrManager transparently uses the native engine when available and
falls back to the existing JS regex loop when it is not.

Cross-platform clipboard access (text read/write, image read) via the
arboard Rust crate. No external tools (pbcopy, xclip, etc.) required.
Ported from Oh My Pi's clipboard module with adaptations for GSD's
architecture (direct AsyncTask instead of task::blocking wrapper).

grammars. Exposes `astGrep` (search) and `astEdit` (rewrite) as N-API functions
with TypeScript wrappers.
Key changes:
- New `gsd-ast` crate with language definitions, glob utilities, and ast-grep core
- Replaces fs_cache/task dependencies with `ignore` crate for file walking

Port glob, glob_util, and fs_cache modules from Oh My Pi's pi-natives crate,
adapted for napi-rs v2. Provides gitignore-respecting filesystem discovery
with a TTL-based scan cache, mtime sorting, file-type filtering, and
node_modules exclusion.

* feat: scaffold Rust native engine with grep module (napi-rs)
Adds a Rust N-API addon architecture inspired by Oh My Pi's pi-natives.
The grep module wraps ripgrep's core crates (grep-regex, grep-searcher,
grep-matcher) and exposes `search()` and `grep()` to Node.js via napi-rs.
Includes:
- Cargo workspace at native/ with engine (cdylib) and grep (lib) crates
- Build script (native/scripts/build.js) producing platform-tagged .node files
- TypeScript wrapper package (@gsd/native) with types and loader
- 6 Rust unit tests + 9 Node.js integration tests (all passing)
