Live-DB test (TEST_DATABASE_URL-gated) for the Phase 3 Slice 6
endpoint covering:
1. Missing both event_type_id + concept_id → ErrInvalidInput.
2. Malformed trigger_date → ErrInvalidInput.
3. Unknown event_type_id → ErrInvalidInput.
4. event_type_id only → parity proxy against
EventDeadlineService.Calculate (Slice-3 legacy delegate). Both
code paths share the unified backend post-Slice-4 so the
returned rule-name multiset must be identical. Selects the
test fixture live: ANY event_type with a non-empty
trigger_event_id bridge to active deadline_rules.
5. concept_id only → returns rules linked by concept_id FK.
Picks the concept with the most rules so we exercise the
ordering path (proceeding_type_id NULLS LAST,
sequence_order). Spot-checks each rule's RuleID parses as UUID.
6. event_type_id + concept_id together → UNION dedupe. Today's
corpus has the two paths on disjoint rule sets so the
additive-count assertion holds; if a future seed links a
concept to a Pipeline-C rule, the dedupe branch fires and the
test logs (not fails) the count divergence for review.
7. Perspective filter — locates a concept with both claimant and
defendant rules (skips gracefully when the corpus lacks one)
and asserts the defendant-perspective response omits every
claimant-party rule.
Build clean, full local test suite green; this test skips when
TEST_DATABASE_URL is unset.
