…tural match (shipped in sint-protocol PR #178) Illya shipped migrationAttestation as a structural precondition on ConstraintEnvelope at sint-ai/sint-protocol#178: when present, the envelope validates only if continuityVerified === true with all four shape fields populated. This makes entity_continuity a scope-grant gate at the execution boundary, not an advisory signal. Changes: - Moved entity_continuity from proposed_signal_type_alignment to signal_types - Match: structural (PR #178 implements the vocabulary.yaml entity_continuity contract at a composition point APS can rely on) - Field: constraintEnvelope.migrationAttestation with sint_definition citing SBR-002 alignment, 5 validation rules, 8 test cases - Notes cite the mutation_boundary descriptor from pending vocab PR #43, reinforcing the cross-spec convergence on the execution-boundary framing - consent_provenance stays in proposed_signal_type_alignment, upgraded to partial with composition note pointing at policy_bundle.consent_chain + APS delegation chain - Updated last_reviewed to 2026-04-23 and added refresh note Validator: 0 errors on sint.yaml (only pre-existing _test-invalid.yaml errors remain).

Summary
Follow-through on the commitment made in sint-ai/sint-protocol#178 — when pshkv shipped
migrationAttestationas a structural precondition onConstraintEnvelope, thecrosswalk/sint.yamlentry forentity_continuityneeded to move fromproposed_signal_type_alignment(markedno_mapping) to the mainsignal_typessection (markedstructural), because SINT now implements the vocabulary.yamlentity_continuitycontract at a real composition point APS issuers can compose against.Changes
entity_continuitypromoted. Moved fromproposed_signal_type_alignmenttosignal_types. Match:structural. Field:constraintEnvelope.migrationAttestation. Definition cites SBR-002 alignment, 5 validation rules, 8 test cases, forward-compatibility across envelope versions.ConstraintEnvelopeis attached to a delegation, the migration-attestation check becomes a precondition on every action the envelope governs. Notes also reference themutation_boundarydescriptor from pending vocab PR feat(vocab): add measurement_point to entity_continuity descriptor #43 (nutstrut'smeasurement_pointproposal), reinforcing the cross-spec convergence on the execution-boundary framing.consent_provenanceupgraded. Stays inproposed_signal_type_alignmentfor now since vocabulary.yaml hasn't added it canonically yet. Match upgraded frompartialto stillpartial(the validator's allowed set doesn't includeclose_match, which would be more accurate). Notes now point atpolicy_bundle.consent_chain + APS delegation chainas the composition surface, with a v1.1 path via sint-protocol PR #168.last_reviewedbumped to2026-04-23. New refresh note documenting the promotion.Why this is a crosswalk PR and not a vocabulary change
This PR only edits
crosswalk/sint.yaml. It does not propose any change tovocabulary.yaml. Theentity_continuitysignal_type was already canonical (merged via PR #28 on Apr 17). This PR just reflects that SINT now implements it.Validator
Zero errors on
sint.yaml. The 5 errors the validator reports are all in_test-invalid.yaml(intentional negative fixtures) and pre-date this PR.Review checklist (5-check protocol)
ConstraintEnvelopeMigrationAttestationinterface inpackages/core/src/types/protocol.ts, 5 validation rules inpackages/core/src/constraint-language.ts, 8 new test cases inpackages/core/__tests__/constraint-language.test.ts. All verifiable.Cross-refs
