**Phase Goal:** Sync recipient and shipment data from GitHub and Shopify with reliable periodic polling.
**Verified:** 2026-02-27T23:02:12Z
**Status:** passed

## Goal Achievement

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Recipients import from GitHub project source | VERIFIED | `project_client` + `github_ingest` tests |
| 2 | Invalid/incomplete mappings are skipped with warnings | VERIFIED | `github_ingest_mapping_skips_invalid_rows_and_emits_warnings` |
| 3 | Recipient-Shopify linkage supports URL-first and fallback behavior | VERIFIED | `shopify_linker_prefers_profile_url_match_then_fallback` |
| 4 | No-match recipients are preserved with nullable Shopify fields | VERIFIED | `shopify_sync_tests_preserve_recipients_with_no_shopify_match` |
| 5 | Shipment state is normalized from fulfillment + tracking data | VERIFIED | `shopify_sync_tests_normalize_shipment_truth_from_fulfillment_and_tracking` |
| 6 | Scheduler runs adaptive interval with bounded backoff | VERIFIED | `scheduler_backoff_grows_delay_with_caps`, `scheduler_tests_adapts_interval...` |
| 7 | Stale warning triggers only after 12-hour threshold | VERIFIED | `sync_status_policy_only_marks_stale_after_12_hours` |
| 8 | Merge applies provider precedence deterministically | VERIFIED | `merge_precedence_prefers_github_identity_and_shopify_shipment` |
| 9 | Partial and conflicting data is surfaced via discrepancy metadata | VERIFIED | `merge_pipeline_tests_store_conflicts_and_expose_discrepancy...` |
| 10 | Manual overrides are preserved across merge cycles | VERIFIED | `merge_conflicts_and_overrides_preserve_manual_value` |
| 11 | Phase test suite passes end-to-end | VERIFIED | `cargo test -p service -- --nocapture` |
