HappyCodex v1.2.1
HappyCodex v1.2.1 makes native agent spawn context selection explicit.
- Default explicit agent_type, model, or reasoning_effort spawns to a self-contained fork_turns="none" packet.
- Use the smallest positive fork only when a recent raw artifact cannot be faithfully referenced or restated.
- Reserve omitted/"all" for intentional same-agent inheritance.
- Add public-contract coverage for these launch-packet invariants.
Validation: 101 offline tests passed; the focused 11-test routing/firewall suite passed; Skill and plugin validators passed; fresh Exact-final returned GO for ccd14fe.
