- First unit tests for Pax8SyncService, mocking postgresClient.query and
pax8-company-matcher's matchPax8Companies (following
pax8-company-matcher.test.ts's mocking discipline)
- Asserts INSERT INTO pax8_orders / pax8_order_items with companyId bound
into pax8_company_id and amountDue into line_total
- Asserts resolveCostColumns' default (CONFIRM) mapping for both observed
item types (subscription, one-time) per 12-02-SUMMARY.md
- Asserts child-then-parent tombstone ordering (pax8_order_items before
pax8_orders)
- Asserts fullSync's entities include 'orders' and 'company_matches'
No TDD gate — plan is autonomous without a plan-level `type: tdd`
frontmatter; the implementation already existed from Tasks 1-2, so this
follows the same single-commit test-addition pattern established by
12-02-SUMMARY.md's Task 2.
