+# Project release handoff
+
+This is the short project-level handoff for the current LinuxCNC WASM/browser
+port scope. It points a new maintainer to the supported workflow surfaces, the
+required release gates, and the boundaries that must remain blocked until real
+LinuxCNC-owned runtime proof exists.
+
+## Start here
+
+Use these documents as the current handoff set:
+
+- `README.md` for the workspace layout and release validation commands.
+- `docs/panel-entry.md` for browser/UI entry points and shell handoff helpers.
+- `runtime/sdk/README.md` for stable SDK imports from `runtime/sdk/src/index.js`.
+- `docs/opfs-session-persistence.md` for OPFS/session persistence scope.
+- `docs/sim-configs-coverage-handoff.md` for sim-config inventory status.
+- `docs/host-runtime-boundary-handoff.md` for blocked runtime families.
+- `docs/source-reuse-map.md` and `docs/drift-report.md` for LinuxCNC source
+  reuse and non-drift rules.
+- `../PROJECT_COMPLETION_TRACKER.md` for project-level acceptance tracking.
+
+Old turn logs `text1.txt` through `text13.txt` are historical context. Current
+continuation records are in `../text14.txt`.
+
+## Supported current workflows
+
+- INI panel launch, edit/run page, read-only control page, workflow overview,
+  and external shell handoff are exposed from `runtime/ui/ini-panel/`.
+- External shells should use the read-only helpers documented in
+  `docs/panel-entry.md`, including workflow overview embedding mount DOM
+  contract/readiness/renderer/wrapper helpers.
+- SDK callers should import stable helpers from `runtime/sdk/src/index.js`.
+- OPFS/session persistence is host-side storage glue. Parameter and tool-table
+  behavior still comes from the LinuxCNC-backed interpreter SDK calls.
+- Sim-config inventory promotion remains evidence-driven and must keep
+  `unexpected_fail=0`.
+
+## Required release gates
+
+Run these before claiming the current scope is release-ready:
+
+```bash
+git diff --check
+wasm-port/tools/verify_vendor_sync.sh
+wasm-port/tools/verify_no_standalone_cnc_semantics.sh
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_interp_wasm.sh
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_sim_configs_inventory_wasm.sh
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_ini_panel_browser.sh
+wasm-port/tests/ui/node/verify_ui_node_smokes.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+The host aggregate gate includes SDK, OPFS, docs, UI Node, WASM Node, and
+browser smoke coverage. A passing aggregate ends with:
+
+```text
+host_wasm_opfs_browser_smokes=ok
+```
+
+## Expected baseline outputs
+
+The current sim-config inventory release baseline is:
+
+```text
+sim_configs_wasm_node_inventory_executed=28
+sim_configs_wasm_node_inventory_passed=28
+sim_configs_wasm_node_inventory_skipped=131
+sim_configs_wasm_node_inventory_unexpected_fail=0
+```
+
+The expected docs and SDK smoke outputs include:
+
+```text
+project_release_handoff_docs_node_smoke=ok
+opfs_session_docs_node_smoke=ok
+sim_configs_coverage_docs_node_smoke=ok
+host_runtime_boundary_docs_node_smoke=ok
+sdk_surface_node_smoke=ok
+```
+
+The expected browser INI panel smoke outputs include:
+
+```text
+browser_ini_opfs_smoke=ok
+browser_ini_control_page_smoke=ok
+browser_ini_launch_smoke=ok
+browser_ini_workflow_overview_smoke=ok
+browser_ini_shell_integration_workflow_smoke=ok
+```
+
+## Blocked runtime families
+
+These runtime families remain blocked:
+
+- `L4-USER-M-PROCESS`
+- `L4-TOOL-DB`
+- `L4-PYTHON-REMAP`
+
+Do not promote them from skipped/blocked state without LinuxCNC-owned native
+runtime proof followed by Node/WASM and browser/host validation. The opt-in
+runtime probes are documented in `docs/host-runtime-boundary-handoff.md`; they
+must not be run on hosts that do not provide the required LinuxCNC runtime.
+
+## Acceptance checklist
+
+- `git diff --check` passes.
+- Vendor sync and standalone CNC semantic guards pass.
+- Interpreter WASM Node smoke passes.
+- Sim-config inventory has `unexpected_fail=0`.
+- UI Node smoke passes.
+- Browser INI panel smoke passes.
+- Host aggregate smoke passes.
+- SDK exports match `runtime/sdk/README.md`.
+- `docs/panel-entry.md` documents the external shell workflow surface.
+- OPFS/session, sim-config coverage, host/runtime boundary, source reuse, and
+  drift docs all point to the current validation gates.
+- Blocked runtime families remain documented and are not falsely promoted.
+
+## Next maintainer rule
+
+Add new CNC behavior only by reusing vendored LinuxCNC source or a documented
+runtime-edge adapter. JavaScript may stage files, mount UI state, manage OPFS,
+load WASM modules, and call C ABI functions; it must not implement G-code,
+tool, parameter, planner, kinematics, remap, or canonical motion semantics.
