Ticket 051: Subactor Delegation Envelope Conformance and Closed-Loop Self-Healing E2E

ID: ticket-051
Owner: unresolved:human
Status: PLAN
Workflow state: PUBLICATION
Created: 2026-08-27
Receipt: Implemented Subactor delegation envelope validator and closed-loop self-healing simulation with CLI subcommands and example suite; 67/67 pytest tests passing and GOV-PASS.

Implement Subactor Delegation Envelope conformance validation and closed-loop self-healing verification:

Implement src/data2dsl_subactor.py with SubactorDelegationEnvelope parser/validator (ROLE, GOAL, SCOPE, ACCEPTANCE, AUTHORITY, LIMITS, REPORT) supporting text and JSON formats per wellmanifest/how-to-use-subactor.
Add deterministic conformance error codes (COMM-ENVELOPE-001, COMM-ROLE-001, COMM-AUTH-001, POA-GRANT-001).
Implement closed-loop self-healing execution pipeline (simulate_self_healing_cycle) simulating DETECT -> PLAN -> EXECUTE -> VERIFY -> HEAL with immutable SHA-256 evidence.
Expose CLI subcommands validate-envelope and simulate-healing in src/data2dsl_cli.py.
Add comprehensive unit and E2E tests in tests/test_subactor_envelope.py and tests/test_self_healing_e2e.py.
Add structured example suite in examples/06-closed-loop-self-healing/.
Verify all tests pass and governance check passes (GOV-PASS).

AC-01: SubactorDelegationEnvelope parses and validates both plain-text and JSON delegation envelopes with standard error codes.
AC-02: simulate_self_healing_cycle runs end-to-end detection, remediation intent generation, synthetic repair, and verification resulting in SATISFIED.
AC-03: CLI subcommands validate-envelope and simulate-healing execute with JSON outputs and exit codes.
AC-04: Full pytest test suite passes (67 tests, 100%).
AC-05: Deterministic governance gate passes (GOV-PASS).
