From ad4d19392fbbdf6340c69a4bbeece371411828ed Mon Sep 17 00:00:00 2001 From: dborup Date: Wed, 14 Oct 2026 14:23:54 +0200 Subject: [PATCH 1/2] feat(compare): reference-to-many observer comparison over the full window (#122) Relates to #122 Server: GET /api/analytics/observer-comparison computes exact packet overlap between one reference observer and up to 40 compared observers, from a single indexed scan over observations.timestamp (not a browser sample, not transmissions.first_seen). Direction is matched case-insensitively to RX only; TX and unknown/NULL never count. Bounded, cached (30s, #430-style ceiling + reject-before-work) and singleflighted. Frontend: compare.js gains a "One vs. many" mode alongside the existing two-observer workflow (unchanged), with a sortable comparison table, drill-down into the pairwise view, deep-linkable state, and a remembered reference observer.
