From 7afaf007c3d57d660b3ee7f0d782681d47a2f9a8 Mon Sep 17 00:00:00 2001 From: Aaron Stainback Date: Sat, 16 May 2026 08:39:36 -0400 Subject: [PATCH] =?UTF-8?q?shard(tick):=202026-05-16T12:36Z=20=E2=80=94=20?= =?UTF-8?q?pure-git=20tier;=202nd=20multi-Otto=20contamination=20in=203=20?= =?UTF-8?q?ticks?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GraphQL 0/5000 (reset 19min). HEAD bounced from peer's branch back to my PR #3871 branch — 2nd contamination event in 25min. Confirms B-0519 RCA at high rate. Defense pattern stable: git branch --show-current catches at tick start; git switch -c origin/main mitigates. Deferred-PR backlog now: 1221z + 1236z branches awaiting post-reset bundling.
