fix: Whoopsy! band re-learns after a lasting shift (v0.13.2) - #31

Conversation
The band froze while values broke it, so a level shift that stayed never resolved: mean and bounds stayed flat and hits grew without end until someone reset by hand. The engine now keeps the latest outliers and, after WhoopsyRelearn (5) times the longer of window and consecutive results outside the band, takes them as the new window. The incident resolves and the band follows the new level. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Problem
The Whoopsy! band is frozen while values break it. A lasting level shift therefore never became the new normal: mean and bounds stayed flat,
hitsgrew without end and the incident never resolved (seen on the Homepage HTTP check: 60/60 results outside, mean fixed at 82.29, hits 82).Fix
The state keeps the latest outliers. After
5 × max(window, consecutive)results in a row outside the band, they replace the window,hitsresets and the incident resolves. Shorter incidents alert as before. No schema change; existingcheck_staterows work.Tests
