Understanding

The user authorized only a compatibility decision. The target is the current subactor/twin contract at an immutable revision, not a proposal disguised as implemented behavior. The decision must distinguish structural protobuf fit from the stronger semantics actually enforced by the validator and tests.

Execution plan

1. Pin the current clean subactor/twin revision.
2. Inspect Observation and EvidenceRef in the protobuf contract.
3. Trace their normative invariants through the standard, reference profile, validator implementation and tests.
4. Map the implemented contract to data2dsl requirements and select exactly one verdict.
5. Publish one decision document and run governance validation.

Actual changes

• Initialized the bounded ticket and recorded SESSION_EXECUTION_AUTHORIZATION from the request to execute this work.
• Pinned the clean subactor/twin checkout at a3a8b759dc87bc4398f86bf8df25a16f1309314e.
• Inspected and recorded immutable evidence for the protobuf contract, normative standard, generic profile, validator, tests and maturity markers.
• Published ADR-001 with the single verdict EXTEND, field-by-field gaps, the required additive boundary and explicit prohibitions for data2dsl.
• Ran the external Twin test suite and the local governance gate. No product code, dependency or external repository was modified.
• Verified GitHub PR 2 was merged into the default branch and closed the completed ticket through a governance-only update.

Blockers

• None inside the recorded intent; proceed without a second confirmation.
• New authority remains required for destructive action, secret access, new external coordination, material objective expansion and trusted merge.
