Moved the tiny title/memory worker from a Bun Worker thread into a child process spawned via Bun.spawn IPC. The agent CLI gains a hidden --tiny-worker dispatch the parent invokes through process.execPath; the parent SIGKILLs the child on dispose so onnxruntime-node's NAPI finalizer never runs in any address space the agent owns. On Windows that finalizer was segfaulting Bun at shutdown after the tiny title model loaded (issue #1606). Drops the now-dead 'close'/'closed' handshake and the unused parentPort bootstrap, and removes tiny/worker.ts from --compile worker entries in both build scripts plus the regression test that pinned them.
Fixes#1606
- Added tiny-title protocol contracts, including progress-state unions, message payloads, and transport interfaces.
- Added title text utilities to truncate long inputs, wrap `<user-message>` blocks, and normalize generated titles.
- Added tiny-title model registry and helpers with type-safe keys and runtime optional loading via optionalDependencies.
- Added client-side worker orchestration with spawn fallback, request queueing, progress/error routing, and smoke-test APIs.
- Added worker runtime for model resolution, prompt-based inference, lock-based install retries, and close-time cache clear.
- Added usage tips content and rendered one random tip in the welcome component.
- Implemented tip rendering rules to skip narrow boxes, truncate long text, and style output.
- Added tiny-title worker to binary and release entrypoints, including repro test coverage.
- Added tiny-title worker smoke-test execution and shutdown cleanup in the session disposal path.
Listing the coding-agent's own ./src/index.ts as a bun --compile extra entrypoint silently breaks the CLI binary startup. Added a dedicated legacy-pi-coding-agent-shim.ts that re-exports the canonical barrel, registered the shim instead of the package index, and updated the compat resolver to point pi-coding-agent at the shim path.
Added bundled root overrides for legacy pi package imports in compiled binaries and corrected fallback resolution to use canonical @oh-my-pi specifiers.
Fixes#1474
Reviewer caught that the new `legacy-pi-ai-shim.ts` is only referenced
via a computed string path, so Bun's `--compile` static analyzer cannot
trace it into bunfs. The same gap existed for the pre-existing
`typebox.ts` shim — `path.resolve(import.meta.dir, "../typebox.ts")`
collapses to `/$bunfs/typebox.ts` in compiled mode (where
`import.meta.dir` is `/$bunfs/root`), which does not exist in bunfs.
Legacy plugins importing bare `@sinclair/typebox` or `@(scope)/pi-ai`
therefore hit "Cannot find module" in release builds.
- Branch `TYPEBOX_SHIM_PATH` and `LEGACY_PI_AI_SHIM_PATH` on
`isCompiledBinary()`: in compiled mode they point at the
`--root`-relative bunfs entry path with a `.js` extension
(`/$bunfs/root/packages/coding-agent/src/extensibility/<file>.js`);
in dev they keep the `path.resolve(import.meta.dir, "../<file>.ts")`
source path so tests still resolve against the workspace tree.
- List both shims as additional `--compile` entrypoints in
`scripts/build-binary.ts` so Bun actually emits them into bunfs at the
paths the runtime expects.
Verified with a focused `bun build --compile` probe: `Bun.resolveSync`
returns the expected bunfs path for both shims when they are listed as
entries, and fails when they are not. Dev-mode test suite unchanged
(17 pass / 0 fail across the four legacy-pi compat test files).
- Raised the Bun minimum version to >=1.3.14 across package metadata, install scripts, and changelog notes.
- Removed the Photon native image pipeline and added SIXEL-based `sixel` support in pi-natives.
- Migrated coding-agent image handling and resizing to `Bun.Image`, including updated tests and a JPEG quality bump to 80.
- Added HTTP/2 fetch bootstrap with HTTPS-only fallback and updated Bun build flags for autoload suppression/`--keep-names`.
- Replaced `with { type: "file" }` worker imports with `isCompiledBinary()` hybrid: literal string for `--compile` static analysis, `new URL(import.meta.url)` for dev portability.
- Added worker entrypoints as explicit `--compile` args in `build-binary.ts` so Bun emits them into bunfs.
- Added `smokeTestSyncWorker` and `omp --smoke-test` to catch silent worker-load failures in compiled binaries (fixes#1011, #1027).
- Added `isCompiledBinary()` utility to `@oh-my-pi/pi-utils` detecting bunfs path markers.
Standalone Bun binaries on WSL (and any host where the user moves the
binary away from the build-host's checkout) failed to load
pi_natives.<platform>-<arch>*.node. The loader's isCompiledBinary
detection relied on two signals that are both false in shipped binaries:
process.env.PI_COMPILED (bun --define PI_COMPILED=true substitutes the
bare identifier, not property accesses on process.env) and
__filename.includes("$bunfs") (Bun retains the build-host absolute path
in __filename for required CJS modules — only import.meta.url is
rewritten). Detection therefore returned false, embedded-addon
extraction was skipped, and the only candidates probed were the
build-host nativeDir and execDir.
Make embedded-addon presence the authoritative compiled-mode signal
(it is null in the post-build --reset stub, populated when embed:native
ran for the standalone build), eagerly require the manifest, and
extract candidate-path computation into a pure helper covered by a
host-platform-agnostic unit test. Also fix the build-time --define so
process.env.PI_COMPILED is genuinely set at runtime as a defensive
fallback.
