Phase 2: the mapping and sync core.
- ColumbiaCatalogMapper (pure/static, unit-tested): maps an API product to a
PowderCatalogItem. Derives manufacturer (PPG/KP Pigments/Columbia) from
taxonomy+SKU; flags additives into the Powder Additives category; takes base
price from the top-level price with variant fallback; captures variation /
tiered pricing as JSON; parses the free-text cure schedule into all curves
(three degree glyphs, @/at, multi-curve in order, partial-cure -> none) with
the first as the primary temp/time; strips HTML descriptions; joins color
groups; normalizes chemistry; flags clear-coat powders.
- PowderCatalogUpsertService (IPowderCatalogUpsertService): single upsert path
matching on (VendorName, SKU). Copies only feed-sourced fields and leaves
enrichment fields (specific gravity, coverage, transfer efficiency, finish)
untouched so syncs never wipe lazily-enriched TDS/AI data.
- ColumbiaCatalogSyncService (IColumbiaCatalogSyncService): pulls the full
catalog, maps + de-dupes, upserts, then reconciles discontinuations ONLY on a
complete pull (a partial pull throws and aborts before the sweep). Reactivates
reappearing items; records last-synced/last-result platform settings.
- 25 mapper unit tests covering the cure parser, manufacturer derivation,
simple/variable pricing, chemistry, color, and HTML cases from real records.
Full suite green (261 passed).
