feat(3555): QueryRuntimeBridge.executeForCjs synchronous primitive (Phase 5.0 of #3524)
Phase 5.0 of the CJS↔SDK hard-seam migration (parent #3524). Foundational PR. Ships ONLY the synchronous primitive on the SDK runtime bridge plus pinning tests. Per-family CJS router migrations (state.*, verify.*, init.*, phase.*, phases.*, validate.*, roadmap.*, frontmatter.*, config.*) become follow-up enhancements that each reuse this primitive. ## What landed - sdk/src/runtime-bridge-sync/index.ts (155 lines) — public API. Exports executeForCjs(input: RuntimeBridgeExecuteInput): RuntimeBridgeSyncResult. Synchronous; lazily creates the synckit sync function on first call. - sdk/src/runtime-bridge-sync/worker.ts (167 lines) — synckit worker. Constructs a native-only QueryRuntimeBridge (with allowFallbackToSubprocess: false), awaits its async execute, catches GSDToolsError / GSDError, maps classification to the six ADR-0001 canonical error kinds plus exit code. - sdk/src/runtime-bridge-sync/index.test.ts (197 lines, 8 vitest pinning fixtures) — success path; unknown_command; native_failure (shape); validation_error (shape); shape invariants; idempotency. - tests/runtime-bridge-sync-smoke.test.cjs (99 lines, 4 node:test cases) — proves the primitive works from CJS callers via require(). ## Decisions 1. Synchronous-bridging mechanism: synckit. Disqualified: - deasync: stagnant (68 open issues, single maintainer, last release Nov 2025), private Node API (process.binding('uv')), untested on Node 22, documented deadlocks with modern Promise chains. - Sync-native SDK refactor: technically infeasible — acquireStateLock in state-mutation.ts uses await setTimeout for retry backoff; making that fully sync requires either Atomics.wait (which IS synckit), busy-loop (degrades responsiveness), or breaking 100+ SDK consumers. Synckit (v0.11.12) is pure JS, actively maintained (last push today), stable public APIs (Atomics.wait + SharedArrayBuffer), Node 22 compatible, no native compile. 2. Native-only transport inside the worker. The sync bridge uses allowFallbackToSubprocess: false. Unknown commands surface as unknown_command instead of spawning gsd-sdk. Keeps the worker self-contained and predictable. 3. Worker path resolution. resolveWorkerPath() navigates ../.. from the loaded module URL to land at dist/runtime-bridge-sync/worker.js — works under both vitest (loads src) and CJS consumers (load dist). 4. GSDError.Blocked → validation_error. ADR-0001's 6-kind taxonomy has no `blocked` kind; Blocked classification is mapped onto validation_error since the operational shape matches (prerequisite missing). ## Numbers - 8 SDK vitest pinning tests pass. - 4 CJS smoke tests pass. - Full suite: 9286/9286 pass (baseline 9282; +4 from the new smoke test cases). - SDK vitest unit: 1860/1860 pass. - Performance: 80ms first-call cold latency (Worker startup + bridge construction); 0.1ms steady-state per-call latency (10-call average after warmup). Well within budget for CJS dispatcher overhead. ## Canonical error kind coverage - unknown_command: covered with pinning fixture - native_failure: shape coverage (handler that throws) - validation_error: shape coverage (GSDError.Validation + GSDError.Blocked) - internal_error: shape coverage only (eliciting TypeError reliably from a registered handler requires elaborate fixture) - native_timeout: NOT pinned (no registered handler genuinely times out; classification logic present in worker) - fallback_failure: NOT pinned (subprocess fallback disabled by design in sync bridge) The classification logic is in the worker regardless; per-family migration PRs will exercise the unpinned kinds incidentally. ## Wiring - sdk/package.json: synckit ^0.11.12 added as runtime dependency (not devDependency — it's required at runtime whenever a CJS caller invokes executeForCjs). - sdk/package-lock.json: regenerated. - CONTEXT.md: new "Sync Runtime Bridge Module" entry added after Dispatch Policy Module. Existing "CJS Command Router Adapter Module" entry amended with one sentence pointing at the primitive and the per-family migration roadmap. No generator/freshness check needed for this phase — the primitive IS the SDK (not a generated CJS mirror). Closes #3555.

/**
|

* Pinning tests for the executeForCjs synchronous primitive.
|
||||
*
|
||||
* Covers:
|
||||
* - Success path: known read-only command returns { ok: true, data, exitCode: 0 }
|
||||
* - unknown_command: unknown command key returns { ok: false, errorKind: 'unknown_command' }
|
||||
* - validation_error: invalid args to known command returns { ok: false, errorKind: 'validation_error' }
|
||||
* - native_failure: handler that throws a generic Error returns { ok: false, errorKind: 'native_failure' }
|
||||
* - internal_error: handler that throws TypeError returns { ok: false, errorKind: 'internal_error' }
|
||||
* - Idempotency: calling twice with identical input produces identical output
|
||||
* - Sync nature: returned value is not a Promise

/**
|
||||
* executeForCjs — synchronous SDK runtime bridge primitive.
|
||||
*
|
||||
* Provides a synchronous `executeForCjs()` function that CJS callers can use
|
||||
* to invoke any registered SDK command without dealing with async/await or
|
||||
* top-level-await restrictions that prevent CJS from using the async bridge.
|
||||
*
|
||||
* ## Mechanism
|
||||
*
|
||||
* Uses `synckit` (Atomics.wait + SharedArrayBuffer + worker_threads) to run
|
||||
* the async `QueryRuntimeBridge.execute()` in a worker thread and block the
|
||||
* calling thread until the result is available. The worker is spawned lazily
|
||||
* on first call and reused for all subsequent calls (steady-state overhead is
|
||||
* ~1–5 ms per call, depending on handler complexity).
|
||||
*
|
||||
* ## Worker overhead
|
||||
*
|
||||
* - First call (worker startup + registry initialisation): ~150–400 ms.
|
||||
* - Subsequent calls (steady state): ~1–10 ms per call.
|
||||
*
|
||||
* ## CRITICAL: Do NOT call from an async context
|
||||
*
|
||||
* `executeForCjs` uses `Atomics.wait` under the hood, which **blocks the
|
||||
* calling thread**. Calling it from inside an async function that is itself
|
||||
* running on the Node.js main thread event loop will **deadlock** because
|
||||
* the event loop cannot process the worker's response message while blocked.
|
||||
*
|
||||
* Safe callers:
|
||||
* - CJS modules evaluated at require-time (synchronous module initialisation).
|
||||
* - Worker threads that are not using the event loop.
|
||||
*
|
||||
* Unsafe callers:
|
||||
* - Any `async function` on the main thread.
|
||||
* - Anything inside a `Promise` callback on the main thread.
|
||||
*
|
||||
* ## CJS consumption
|
||||
*
|
||||
* ```js
|
||||
* const { executeForCjs } = require('@gsd-build/sdk/dist/runtime-bridge-sync/index.js');
|
||||
* const result = executeForCjs({ registryCommand: 'generate-slug', registryArgs: ['My Phase'], ... });
|
||||
* if (result.ok) console.log(result.data); // { slug: 'my-phase' }
|
||||
* ```

||||
*

||||
