+五十七、2026-06-16 继续执行记录：project release gate execution manifest SDK API
+
+本批继续按“每批必须产出可调用 API、可验证 workflow、可执行 gate、或真实 UI/browser 能力”
+推进，选择 `text15.txt` 下一步建议中的 machine-readable release gate execution manifest/artifact。
+
+本批新增实质能力：
+
+- 新增 SDK API：`createProjectReleaseGateExecutionManifest()`；
+- 该 API 复用 release gate manifest，按 gate 输出每个 gate 的 `command`、`expectedOutput`、
+  `observedOutput`、`evidence`、`passed/unknown` 状态、缺失 gate ID 与 pass/unknown 计数；
+- `createProjectReleaseReadinessReport()` 现在嵌入 `gateExecutionManifest`，让外部 CI/browser
+  dashboard 可直接展示 release gate 执行证据，而不需要解析 shell 脚本；
+- `createProjectReleaseReadinessArtifactValidation()` 现在要求 ready artifact 包含
+  `gateExecutionManifest`，并暴露 `gateExecutionManifestReady`；
+- workflow overview release artifact validation summary/render rows 增加
+  `gate-execution-manifest` evidence 行；
+- 更新 `tests/fixtures/project-release-readiness-ready.json`，使 browser artifact URL workflow 使用
+  新 schema；
+- 更新 SDK README 与 `docs/project-release-handoff.md`，说明 execution manifest、artifact validation
+  evidence chain 与外部 CI/browser dashboard 用法。
+
+本批新增/更新可执行验证：
+
+```bash
+wasm-port/tests/sdk/node/verify_project_release_gate_manifest.sh
+wasm-port/tests/sdk/node/verify_sdk_surface.sh
+wasm-port/tests/docs/node/verify_project_release_handoff_docs.sh

+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_ini_panel_browser.sh
+wasm-port/tests/host/verify_project_release_gate.sh
+```
+
+关键通过输出：
+
+```text

+sdk_surface_node_smoke=ok
+project_release_handoff_docs_node_smoke=ok

+browser_ini_shell_integration_workflow_smoke=ok
+project_release_readiness_artifact_node_smoke=ok
+project_release_gate=ok
+```
+
+本批仍保持 LinuxCNC 语义边界：
+
+- 未修改 vendored LinuxCNC 源码；
+- 未在 JS/browser 中实现 G-code、tool、parameter、planner、kinematics、remap 或 canonical motion
+  语义；
+- 新增内容只属于 release gate evidence packaging、SDK/API surface、browser/UI artifact validation
+  render rows、docs 和测试 gate；
+- blocked runtime families 仍不 promotion。
