 - **Permissiveness gaps:** of 334 invalid models we wrote ourselves, the reference rejects 4 that we accept by default, and 319 both reject; 4 further cases agree only when we are asked strictly. We authored every one of these cases ourselves, so the denominator measures the reach of our own corpus and not our conformance; agreement reached only under an opt-in strict mode is weaker evidence than agreement by default ([rejection oracle](docs/project/pilot-rejection.md), `go run -C tools ./cmd/pilot-reject`).

 **Test coverage:** top-level `Test` functions (counted from the `_test.go` files, as `go test ./...` runs them) covering parsers, semantics, runtime (actions, states, instances, operators, validation), behind golden ASTs, negatives, execution conformance cases, golden traces, runtime robustness cases and gRPC conformance and robustness cases. The figures are counted from the tree when the documentation site is built into the test inventory of [spec compliance](docs/project/spec-compliance.md), never committed, so a branch adding a test does not rewrite this page. A test skips only for want of something the run did not provide, and says what: the held-image round trip declines a conformance case that creates no instance, a few gate on a PDF or Mermaid toolchain, a pinned pilot artifact, the PSSM suite, a locale, a case-insensitive filesystem or a live Flexo stack, and the OMG corpus gates skip until the corpora are downloaded unless asked to fail.
 **Parser coverage:** 110/110 bundled library files parse cleanly — the 94 official SysML v2 standard library files and the 16 non-normative OpenSysML extensions: `OpenSysML Libraries/AnalysisRecords.sysml`, `DiagramLayout.sysml`, `DocumentQueries.sysml`, `IdentityMetadata.sysml`, `MOSA.sysml`, `MigrationMetadata.sysml`, `OOSEM.sysml`, `OpenSysMLMathFunctions.kerml`, `OpenSysMLRenderings.sysml`, `RandomFunctions.kerml`, `Simulation.sysml`, `StateActivity.kerml`, `StateMachines.sysml`, `StateSpaceIntegration.sysml`, `Stochastic.sysml` and `SysMLValidation.sysml`. Conformance verified by [stdlib_conformance_test.go](internal/workspace/libs/stdlib_conformance_test.go). Grammar reference: [OMG Xtext grammar](https://github.com/Systems-Modeling/SysML-v2-Pilot-Implementation/tree/master/org.omg.kerml.xtext/src/org/omg/kerml/xtext).
 **Behavioral execution:** Calc/constraint/requirement/satisfy functional. Action/state executors handle nested invocation, control flow keywords, loop and conditional statements and the send statement (<!-- doc-counts:begin conformance-passing -->every conformance case passing<!-- doc-counts:end conformance-passing -->). Coverage is self-assessed against the specification text and the normative library: the pinned OMG pilot implementation evaluates expressions but does not execute actions or state machines headlessly, so no external implementation currently adjudicates these rows. See [spec compliance](docs/project/spec-compliance.md).
-**Reference differential:** 912 files compared diagnostic-by-diagnostic against the pinned OMG pilot implementation (`2026-08`), 510 in full agreement; every divergence is enumerated and adjudicated in [the differential](docs/project/pilot-differential.md), reproducible with `go run -C tools ./cmd/pilot-diff`.

 **Rejection oracle:** the reverse direction — do we reject what the reference rejects? 334 hand-written invalid models validated by both implementations, 323 rejected by both, 0 the pinned pilot rejects and we accept; the remainder only we reject — the control-node succession rules the pinned pilot leaves unimplemented and a non-Boolean succession guard it accepts once the standard library types it — and every permissiveness gap is enumerated with a reproducer and likely root cause in [the rejection oracle](docs/project/pilot-rejection.md), reproducible with `go run -C tools ./cmd/pilot-reject`. We wrote every case, so the count measures our coverage of the rejection surface, not our conformance — a sample, not a proof.
 **Training examples:** 100/100 files report no semantic errors, gated by `tests/corpus/testdata/training_examples_expected.txt`; the gate does not count execution-scope warnings. Download with `./scripts/download-training-examples.sh` (from the [OMG training directory](https://github.com/Systems-Modeling/SysML-v2-Pilot-Implementation/tree/master/sysml/src/training)). See [training examples](docs/project/training-examples.md) for analysis.
 **Semantic layer:** a complete implementation of runtime operators, feature chains and validation rules. See [examples/semantic-layer/](examples/semantic-layer/) for a full demonstration.

+- An element filter (`filter @T;`, `import P::*[@T]`, `expose X::**[@T]`) and a classification (`@T`, `@@T`) now test conformance against the Type element the name resolves to, through its specialization closure, rather than against the qualified name: a type named through an `alias` or a re-exporting import selects what the aliased Type annotates, and a distinct Type that shares the qualified name (the same package opened in another document) selects nothing it does not annotate. The name alone decides only when it resolves to no element, or between two library copies of one declaration (a workspace namesake of a library type is not that type); likewise `Base::Anything` is the top type every type conforms to only as the library declares it, not as a workspace type of that name.
