From c4e8190656bab753307f9aef861a9915ec85e4fa Mon Sep 17 00:00:00 2001 From: Erik Date: Wed, 24 Jun 2026 09:38:10 +0200 Subject: [PATCH] =?UTF-8?q?feat(go-services):=20tracker-go=20=E2=80=94=20c?= =?UTF-8?q?omplete=20the=20Phase=201=20read=20API?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the rest of the read-side endpoints to the Go tracker, all parity-checked against the live Python service: - DB reads: /stats/{c}, /portals, /spawns/heatmap, /server-health, /character-stats/{c} (stats_data JSONB merged to top level), /combat-stats[/{c}], /inventories, /inventory/{c}/search. - 5-minute totals cache + /total-rares, /total-kills. - Ingest-only state returned as Python's empty/default shapes (/quest-status, /vital-sharing/peers, /equipment-cantrip-state/{c}); /issues (flat file), /me (401 until cookie verification lands). - Streaming reverse proxy to inventory-service (/inventory/{c}, /inventory-characters, /search/*, /sets/list, /inv/{path...} incl. the SSE suitbuilder stream). - compare/compare_endpoints.py: structural parity for all read endpoints + exact-match check for /character-stats and /combat-stats on OFFLINE chars (online chars legitimately differ — Python serves a richer live overlay that Phase-1 Go lacks until ingest). Verified live: 14/14 endpoints structural-match, 8/8 rich offline chars exact-match on /character-stats.
