From dfe050e8d4e15686870821dad5da86153e201a5d Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Fri, 31 Jul 2026 19:03:08 -0700 Subject: [PATCH] FN-8640: add FNXC stamp anomaly advisory Add a non-blocking census for implausible future-dated FNXC stamps. - Classify tolerated future stamps by timezone plausibility and report notable anomalies. - Add injectable gate seams and coverage for advisory, report, baseline, and discovery behavior. - Document the advisory and preserve read-only check-mode baseline handling.
