From 4e54fd62189cfb00e92d356c41e394784d80d42b Mon Sep 17 00:00:00 2001 From: Dave Date: Sun, 30 Aug 2026 08:45:23 +0200 Subject: [PATCH] feat(orders): add quote-match backlog sweep with age-gap reporting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The matcher only runs on orders created from now on. This sweeps the historical backlog plus any order whose lines changed after creation. - sweepUnmatchedOrders in order-quote-link-service.ts walks quote_matching_attempted = false && quote = '' (the codebase's pattern for an empty relation, verified against orders-service.ts usage) in batches, projecting only id (the wider order fields are re-fetched inside suggestQuoteForOrder). - bucketAgeGaps exposes the histogram that lets FUZZY_WINDOW_DAYS be re-tuned from real data instead of the 90-day estimate. - POST /api/v1/orders/quote-match/sweep is the agent-auth surface with maxDuration=300 for the 500-order worst case. Tests cover the filter shape, the field projection (load-bearing — over-projection wastes wire bytes), the no-op on no-match path, the fault tolerance (one row throwing doesn't kill the batch), and all six histogram bucket boundaries including the ≤ N vs < N edges.
