Audience: agent · Diátaxis: reference · Kind: contract
Census of DFM case and check files. Not behave proof and not a CAD canonical write.
Index: workspace source map. Domain coverage stays on engineering domains.
dfm-check-case/1.0: attested STEP target, object build volume, declared Z-min filter,
measured verdicts. Distinct from documentary printability-check-case/1.0
Attests a DFM STEP as canonical design.write-geometry@1 output. Production STEP is
the cad-asset-<capture>-target-<n>-<stepDigest> (or PartDefinition
…-definition-…) child of geometry-<capture>; isolated CAD is refused
Closed MRTR grammars for industrialize.seal-dfm-case@1 and
industrialize.run-dfm-checks@1
Provider-free dfm-case-capture/1.0 seal envelope
Measured dfm-check-capture/1.0: three mcp-dfm tools, Z-min trace, recomputed
evaluations on reread
Provider-free seal of one signed DFM case; attests the STEP via
attestCanonicalWriteGeometryStep; never calls mcp-dfm
Trusted measured run: three tools with expected_step_sha256, declared Z-min filter,
named publishable failures. Not observe-printability
Three-state WAL dispatched → capture-recorded → completed for measured DFM; a
dispatched record without capture is not retried
