From cbb87faab02c2a3856a6829c41eac9465de915b6 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Fri, 16 Oct 2026 23:14:18 +0300 Subject: [PATCH 42/45] fix(schedule): ensure unique creation timestamps for cron jobs Job creation time doubles as the identity for runs written against a job, so a job removed and registered again within the same millisecond could collide with its predecessor. Insertion now waits for a fresh millisecond before writing, and collection setup only declares the primitives the store actually uses.
