+# ITC-WP-0018 — EmissionCadenceDeclaration Semantic Contract
+
+## Goal
+
+Adopt the King’s Guard handover as the ecosystem-wide, versioned semantic
+contract for declaring expected stream emission, while leaving NetKingdom
+security obligations in the importing NetKingdom profile.
+
+## T01 — Review ownership and assimilate the handover
+
+```task
+id: ITC-WP-0018-T01
+status: done
+priority: high
+state_hub_task_id: "b6cba288-1edf-557c-b692-cd24058fb9d6"
+```
+
+Preserve the handed-over draft, compare its concepts with the existing
+Observability and Governance models, and record the authorized `adapt`
+disposition from `GH-DEC-2026-004`.
+
+## T02 — Publish the generic contract and validation schema
+
+```task
+id: ITC-WP-0018-T02
+status: done
+priority: high
+state_hub_task_id: "cca8a6e6-03fe-50a1-9f0d-84cbc8b92cac"
+```
+
+Publish the generic forms, fields, validation semantics, compatibility rules,
+and a non-authoritative worked example. Do not encode the NetKingdom rule that
+rare load-bearing classes require heartbeat plus reconciliation.
+
+## T03 — Register, retrieve, validate, and announce
+
+```task
+id: ITC-WP-0018-T03
+status: done
+priority: high
+state_hub_task_id: "9df9fd50-26e0-531e-a0a2-9f92eed5f2b3"
+```
+
+Register the artifact and schema, regenerate retrieval assets, run the full
+validation and test suite, and notify the handing-over and deciding repositories.
+
+## Acceptance
+
+- InfoTechCanon is the sole owner of `EmissionCadenceDeclaration` semantics.
+- The schema validates both generic forms and rejects incomplete form payloads.
+- NetKingdom-specific evidence classes and MUST/SHOULD policy are not defined here.
+- The artifact is discoverable through the CLI/JSON/API retrieval surfaces.
+- Generated assets, validation, tests, work records, and State Hub agree.
+
+## Result
+
+Completed 2026-09-04 in canon 0.7.0. The handed-over draft was adapted into the
+generic standard and schema, the security-profile boundary was preserved, the
+worked example and structural validation were published, and all retrieval
+assets were regenerated. `make validate` reports 0 errors and 0 warnings;
+`make test` passes 29 tests.
