## Sections Implemented

- Section 0: 3 EventTypes ✓
- Section 1: OrderManager with `dataclasses.replace` and 5 rejection reasons ✓
- Section 2: EventTypes added ✓
- Section 3: OrdersConfig + SystemConfig wiring ✓
- Section 4: finalize.py wiring (public `runtime.order_manager`) ✓
- Section 5: Proactive context injection at `proactive.py:1370` ✓
- Section 6: REST endpoints `/api/orders` and `/api/orders/post/{post_id}` ✓

## Test Results

`pytest tests/test_ad440_chain_of_command_delegation.py -v -n 0` → 16 passed in 0.41s.

## Engineering Principles Compliance

- ✓ Demeter: `runtime.order_manager` public (sets Wave 5 precedent)
- ✓ `dataclasses.replace` for frozen-dataclass state transitions
- ✓ Type annotations on all public methods
- ✓ Pydantic config with `Field(ge=..., le=...)` validators
- ✓ `requires_consensus=True` not used — order issuance is advisory not destructive
- ✓ Subordinate-side capabilities retain their own consensus rules

## DECISIONS.md Entry

Recorded three architectural decisions: (1) orthogonality with `cmd_order` Captain directives, (2) in-memory storage with TTL over disk persistence, (3) no consensus gating on order issuance itself. Plus the cross-cutting **Wave 5 public-attribute wiring precedent** that AD-455 / AD-468 / AD-439 mirror.
