 `isSupportedIniPanelShellSessionHandoffPackage()`，为 package 增加 versioned schema 与 focused
 compatibility predicate，便于外部 shell 在消费 package 前做单点兼容性检查；仍保持只读，不新增
 控制按钮，不解析 G-code。
+
+八、2026-06-15 继续执行记录：INI panel shell handoff package schema gate
+
+本轮按“第一原则：加快实质性推进”继续推进 browser/UI workflow，为 shell handoff package
+新增 versioned schema 与 focused compatibility predicate，让外部 shell 能在消费 package 前做
+单点 shape 兼容性检查。
+
+完成内容：
+
+- `ui-shell.js` 新增 `createIniPanelShellSessionHandoffPackageSchema()`；
+- package schema 输出：
+  - `apiName: "ini-panel-shell-session-handoff-package"`；
+  - `packageVersion: 1`；
+  - `fields`；
+  - `manifestFields`；
+- `ui-shell.js` 新增 `isSupportedIniPanelShellSessionHandoffPackage()`；
+- predicate 检查：
+  - package 对象存在；
+  - `apiName` 匹配；
+  - `packageVersion` 匹配；
+  - package 顶层 required fields 存在；
+  - `manifests` 对象存在；
+  - manifest required fields 存在；
+- `createIniPanelShellViewModel()` 新增：
+  - `shellSessionHandoffPackageSchema`；
+  - `createShellSessionHandoffPackageSchema`；
+  - `isSupportedShellSessionHandoffPackage`；
+- `createIniPanelLaunchApiManifest().methods` 新增：
+  - `getShellSessionHandoffPackageSchema`；
+  - `isSupportedShellSessionHandoffPackage`；
+- `launch.html` 的 `window.linuxCncIniPanelLaunchApi` 新增真实 browser 入口：
+  - `getShellSessionHandoffPackageSchema()`；
+  - `isSupportedShellSessionHandoffPackage()`；
+- `ini_panel_launch_smoke.html` 校验真实 launch iframe：
+  - package schema version 为 1；
+  - 当前 package 可支持；
+  - 错误 package version 被拒绝；
+- `ini_panel_shell_integration_workflow_smoke.html` 校验外部 shell workflow 能读取
+  package schema，并用 predicate 确认 package 可支持；
+- `verify_ini_panel_shell_integration_manifest.mjs` 覆盖：
+  - package schema 完整 shape；
+  - valid package 支持；
+  - 错误 version、错误 apiName、缺 package 字段、缺 manifest 字段、null 被拒绝；
+- `verify_ini_panel_ui_shell.mjs` 覆盖 shell view-model 的 package schema 和 predicate；
+- `verify_ini_panel_launch_api_manifest.mjs`、`verify_ini_panel_entry_docs.mjs` 与
+  `docs/panel-entry.md` 同步记录和校验新 helper/API；
+- 未新增控制按钮；
+- 未执行 action-plan；
+- 未解析 G-code；
+- 未解释 canonical events；
+- 未新增 JS CNC 语义；
+- 未改变 OPFS/session persistence、LinuxCNC interpreter、tool、parameter、planner 或
+  LinuxCNC-owned runtime semantics。
+
+验证已通过：
+

+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_sim_configs_inventory_wasm.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+关键输出：
+
+```text
+ini_panel_shell_integration_manifest_node_smoke=ok
+ini_panel_launch_api_manifest_node_smoke=ok
+ini_panel_ui_shell_node_smoke=ok
+ini_panel_entry_docs_node_smoke=ok

+sim_configs_wasm_node_inventory_skipped=131
+sim_configs_wasm_node_inventory_unexpected_fail=0
+host_wasm_opfs_browser_smokes=ok
+```
+
+下一步建议：
+
+继续推进 browser/UI workflow 与文档化可执行工作流。下一批建议新增一个只读
+`createIniPanelShellSessionHandoffPackageReport()` 或等价 helper，把 package schema support、
+missing package fields、missing manifest fields、version/apiName mismatch 和 checklist blocking
+reasons 合并成 display-ready report，便于外部 shell 在拒绝 package 时显示原因；仍保持只读，
+不新增控制按钮，不解析 G-code。
