+# mwrap category and ONNX Runtime SDK implementation
+
+The new mwrap category is flat under pkgs/mwrap. Existing clients scan one category level and the publishing script copies pkgs unchanged; no staging conversion or mcpp engine change is required. Consumers live under tests/mwrap and participate in the same selection/shard/timing entry points as existing examples.
+
+compat.onnxruntime owns the official MIT-licensed 1.25.1 CPU SDK, including exact platform checksums. The module wrapper remains in mcpplibs/onnxruntime-m and exposes upstream Ort/C names. The provider supports Linux glibc x86_64, macOS arm64 and Windows x86_64 MSVC ABI. Unsupported architectures/libcs fail explicitly. Linux runtime closure declares gcc-runtime and glibc; it never farms libc or an ELF loader from the host.
+
+Local checks: strict descriptor parse, cross-package references, duplicate/platform version lint and shard inclusion passed. Isolated SDK installation and real inference/header coexistence passed with LLVM 23.1.3; GCC 16.1.0 also passed, followed by actual template creation/build/inference. Native wrapper CI pins SDK provider commit 3067e52abc0165b453ea3acac4022895ebf7d9bc.
+
+The formal English/Chinese mwrap specification records upstream[.N] versions, modules versus API namespaces, macros, optional features and executable quickstart templates. The package skill links this common specification. Autoupdate is not enabled for the SDK yet: updating it requires changing archive directory names, API inventory and ABI verification, rather than only replacing a URL version.
+
+Checkpoint state: SDK provider and category infrastructure first. The opencv/onnxruntime wrapper descriptors must be added only after immutable source archives and checksums are verified and install/template consumers execute through this index. No placeholder published versions, release tags or merges are performed here.
+
+CI caught a semantic difference in migrating root [indices] to [workspace.indices]: the latter merges namespace entries into members, registering the same physical index twice for non-compat members and triggering xlings ambiguity. Keep the existing root [indices] replacement semantics deliberately; this is supported compatibility behavior in the pinned client. No engine patch or per-member mass rewrite is needed. Reproduction: graphics side-effects job 120643941884 failed before installing any graphics package.
+
+The real wrapper archive de3a0a9 was downloaded twice and pinned as SHA256 24d4bc26d2f426e3643f21d289d92e7a23b3ba54524a099a1079c1c490915251. Its CPU inference and public SDK helper consumer passed through index installation. Testing the wrapper and compat SDK together confirmed both namespace-routing constraints on the current client; tests/prepare_mwrap_indices.py now provides unchanged namespace-scoped test views, while check_installed_template.py independently tests the complete unchanged published layout with no source pre-seeding or dependency rewriting.
+
+The unchanged full-index installed-template flow passed in a fresh home: real wrapper/SDK archives and LLVM were installed, mcpp new rendered the default inference project, and its original dependency resolved and ran Identity inference. The updater audit now implements the documented immutable-commit exception rather than demanding a fake release template. All 14 updater adapter tests and the full real audit passed (85 automatic declarations, one manual snapshot), retaining historical-byte guards. Candidate selection/preparation also recognizes tests/mwrap and fully qualified dependency keys.
+
+Cross-platform CI correction: namespace-view metadata is explicitly decoded as UTF-8 on Windows. The ecosystem Vulkan check also exposed two header/runtime adapter anchors defaulting to static while reachable from several shared images; their providers now default to shared form, with explicit packaging revision 1 on current entries and unchanged source URLs/hashes. The consumer can still choose linkage. Llama Vulkan CI pins this candidate index commit rather than requiring the PR to merge first.
+
+## Existing-wrapper template archive checkpoint
+
+- All six -m repositories now use concise root READMEs (normally <=100 lines per language), with detailed usage under docs/. The bilingual mwrap spec and authoring skill record the shared structure and the local aggregate resource limit.
+- Added immutable candidate versions for FFmpeg 8.1.2.1, ImGui 1.92.8.1 and gRPC/runtime-plugin-rule 1.83.0.1. Published older version blocks are unchanged. Existing package/module identities remain compatible. ImGui and gRPC now declare tag-based automatic update URLs; coupled gRPC manifests are still version-checked by source CI.
+- CPU/headless workspace consumers live in tests/mwrap/{ffmpeg-cpu,imgui-headless,grpc-cpu}/tests, so mcpp test executes their behavior checks rather than merely building an application. Windows gRPC explicitly remains unavailable with the declared OpenSSL provider.
+- Each candidate's full-commit archive was downloaded twice with identical SHA256. Updated the unpublished ORT/llama candidates to include the reviewed README revisions. Archive references at this checkpoint:
+
+- onnxruntime-m: `576c780bfcbd792c7f4194942c90324f183a48aa`, SHA256 `3654811f65b98ade75b5e46fe59a0c4479d815aa7fa9aceff9f9cc3fffd8ddc1`.
+- llama.cpp-m: `5028a1aa4f741db4dbd86d6ebd1928ef21027147`, SHA256 `9b21c35c17e801ceee1165960eefbf7280ad50e14aaf3ea5603fbf2c4ab911de`.

+
+Local evidence: OpenCV LLVM/GCC all-module strict tests each pass fourteen binaries; the GCC ORT adapter fix also passes actual CPU-profile inference. FFmpeg's managed-NASM default template strictly builds and decodes three generated frames. The full index audit covers 90 automatic declarations plus one manual snapshot and preserves all historical version blocks; fourteen updater regressions and changed-descriptor all-platform grammar/name/syntax checks pass.
+
+The new complete-index ImGui archive/template check is running in a fresh MCPP_HOME. Final fresh-archive checks for changed source revisions, the new workspace test entries and native CI are not yet complete. gRPC's cold installed-template check has its own Linux/macOS jobs with a 210-minute limit; it does not consume a workspace shard's existing 90-minute allowance. No release readiness is inferred from source CI or archive checksums alone.
+
+Local heavy commands run serially in mwrap-tests.slice with CPUQuota=1600%, MemoryHigh=28 GiB, MemoryMax=32 GiB, TasksMax=512, taskset 0-15 and MCPP_JOBS=6 on this 32-logical-CPU/62-GiB host. Check current available resources and disk before each check; retain at least 6 GiB free during builds. No engine change, merge or tag is included.
+
+## Candidate scanner and host-tool consumer correction
+
+The b22a9a8 candidate scan stopped with `no candidate consumer: grpc:grpc-plugin`. Added a dedicated grpc-tools consumer for the indexed plugin and grpcgen host module; it resolves both exact 1.83.0.1 archives through separate unchanged namespace views, builds the host binary and verifies its path plus the rule's generation metadata. This is host-tool build/availability coverage, including planned native Windows checks, not a Windows runtime/codegen support claim. Actual service generation/RPC remains covered by the default gRPC templates on supported Linux/macOS targets.
+
+The scanner now finds normal and build dependencies inside target tables, and prefers dedicated tests/mwrap consumers over older platform-gated examples. Two regressions cover these boundaries, including build-dependency version replacement. All sixteen updater tests pass; an actual full candidate-matrix reproduction produces 23 build/run jobs and selects grpc-cpu, grpc-tools, imgui-headless, ffmpeg-cpu and llamacpp-cpu as intended. The full audit still preserves historical versions and reports 90 automatic descriptors plus one manual snapshot.
+
+Local strict actual index tests now pass all four new members: ffmpeg-cpu (real 16x16 frame), imgui-headless (positive draw vertices), grpc-cpu (status/credentials) and grpc-tools (built host plugin plus imported rule). A fresh complete-index ImGui archive/default-template installation also passes with positive draw data and no display. These results supplement the source/template CI; all new native matrix jobs remain required before release readiness.
+
+## Complete-index fixture, seven-wrapper and OpenCV archive checkpoint
+
+The ba9a72e native candidate jobs exposed two real test-fixture problems: preparing only the namespace under test hid coupled unpublished plugin/rule versions, and registering full candidate views through multiple project aliases caused ambiguous candidates in fresh CI. The new prepare_builtin_index.py installs the complete unchanged pkgs/index.toml layout into one isolated test home's built-in index. Updater candidate preparation uses it for all namespaces; grpc-tools uses an empty member [indices] table to override the legacy workspace redirect. Publication layout remains unchanged, with no staging/path conversion or engine change.
+
+A fresh standalone strict plugin/rule consumer passed in 201.08 seconds and its lock proves both exact 1.83.0.1 identities. A separate fresh actual workspace grpc-tools invocation passed its host-binary behavior in 184.46 seconds; workspace lock verification proves both identities too. The existing workspace-root [indices] deprecation remains a documented baseline, so the actual workspace command follows CI's non-strict mode; standalone candidate consumers stay strict. The first workspace diagnostic harness looked for a member lock instead of the root lock after the successful test; postprocessing was corrected and the root lock was independently verified. The grpc-cpu consumer now includes the standard string header explicitly after GCC CI exposed missing string comparison declarations. All seventeen updater regressions pass.
+
+The organization audit includes seven -m repositories: Godot was omitted from the initial six-repository inventory. Godot 10.0.0-rc1.1 is now indexed with a standalone math behavior consumer and an actual installed-template CI check. Its source head 40f72d5 has Linux/macOS/Windows CI green, including the explicit one-symbol Windows extension export check; actual loading by a Godot process remains separate scope. All seven root READMEs are 42–52 lines per language, with details under docs/.
+
+Added the new canonical mcpplibs.mwrap.opencv@5.0.0.1 descriptor under pkgs/mwrap and its tests/mwrap/opencv-cpu consumer. The first immutable 52f4c8f archive passed a real strict installed image/scalar consumer in 67.22 seconds: exact grayscale pixels, PNG/JPEG roundtrips, saturation/rounding and generic min/max/makePtr. The actual default image template also installed and built strictly in a fresh home. Its release packaging audit then correctly failed because the old source manifest deployed no OpenCV license tree. Source checkpoint 5da7fc8 now explicitly deploys all fourteen retained wrapper/upstream license/copyright files with original paths. The installed-template helper checks each byte and executes the relocated application with a clean HOME/runtime environment, verifies its 64x64 PNG and, on Linux, confirms loader dependencies stay inside the bundle. The fixed archive/deployment rerun is in progress and is a native CI gate; no release readiness is claimed yet.
+
+The gRPC native source workflow completed its advanced program but failed a stale unscoped generated-source assertion. New source 0d11b22 checks common/types.pb.cc beside the real mock output, finds the actual generation graph by its edge rather than filesystem order, and removes the expired pre-cache-fix local-cache workaround. A local LLVM advanced generation/RPC rerun passed in 3m40s and all generated outputs/edge metadata were checked; latest native source CI is running.
+
+Each candidate below was downloaded twice with matching SHA256. Existing published archive versions are unchanged. The full audit reports 91 automatic declarations and two reviewed immutable snapshots; the five current new/updated archive descriptors pass resolver grammar and name/namespace/mirror/version checks. No merge, tag or release has been performed.

+## Refresh ordering and final archive evidence
+
+On 815c647, updater candidate jobs for FFmpeg/llama failed because the workflow prepared the candidate and then ran mcpp index update, replacing it with the published snapshot. This is a fixture ordering bug, not missing package support. An actual pinned-client reproduction installed the candidate first, refreshed, and then correctly failed to resolve 8.1.2.1 against the published 8.1.2 entry. Preparing the complete candidate after refresh restored real archive/template lookup. The workflow now reapplies the fixture after registry setup/index refresh; no engine or low-level registry configuration changes are needed. All seventeen updater regressions still pass.
+
+The final OpenCV 5da7fc8 archive passed strict GCC 16.1.0 image/scalar consumption in a new home (152.96 seconds). Its actual fresh default template built strictly, packed in release/self-contained mode and ran after relocation with clean HOME/runtime paths. All fourteen wrapper/upstream notices matched their installed source bytes; the relocated application generated a valid 64x64 PNG and the Linux loader resolved every file-backed dependency within the bundle. The previous 52f4c8f package was independently shown to lack that license tree, so the new deployment gate detects the real packaging regression.
+
+The final Godot 40f72d5 archive/default math template also passed strict fresh-home LLVM build and execution (3m29s build); it printed vector length five and cross product (0,0,1). Source native CI was already green on all three targets. Current OpenCV/gRPC/index native heads remain under validation. No merge, tag or release is included.
