Phase 3 Slice 4 test coverage. Adds:
- TestEvalConditionExpr (20 sub-cases): AND/OR/NOT compositions,
single-flag leaf, nested AND-of-OR-and-NOT, empty-args
vacuous-truth semantics, NULL-expr → legacy condition_flag
fallback (preserves the AND-of-flags behaviour for any
pre-Slice-2-style row), malformed JSON / unknown op / malformed
NOT all defensive-true (rule still renders).
- TestWireFlagsFromPriority (6 sub-cases): exhaustive enum +
safe-default for unknown values. Matches the reverse of the
Slice 2 mig 083 backfill mapping.
- TestApplyDuration_Matrix (7 sub-cases): 4 units × multiple
timings × calendar/holiday rollover. Includes the
Thu+1d-over-Tag-der-Arbeit edge that exercises the
weekend+holiday cascade.
Test file housekeeping:
- Drops TestIsCourtDeterminedRule (the function it tested no
longer exists; equivalence is preserved by mig 082's WHERE
predicate and verified by the Slice 2 backfill integrity test).
- Drops the unused models import that becomes orphaned.
- Renames the EventDeadlineService.applyDuration / addWorkingDays
method-receiver tests to call the package-level functions
directly. Same test names + expected dates; only the helper
signature shifted.
- Parity test still calls the same applyDuration body, now via
the unified helper.
Full test suite green locally (live DB tests skip when
TEST_DATABASE_URL is unset, as ever).
