From 2bcc965efbd16328e52cb64d7ea2ea8d09e65945 Mon Sep 17 00:00:00 2001 From: Chris Troutner Date: Fri, 4 Sep 2026 18:59:27 -0700 Subject: [PATCH] Review feed-query-performance: remove dead full-scan methods, harden mutation coverage Remove the full-scan methods the capped-scan optimization replaced (topLevelPostTxids, countTopLevelPosts, countTopLevelPostsByAddr, buildReplyCountMap) and their tests, keeping the backwards-compat wrappers. Add hardening tests to kill 4 mutation survivors (raw scan bound, viewerAddr fallback). Refresh mutation manifests and Gherkin acceptance-mutation stamps.
