Spend alerts before surprises

Unexpected token bills usually come from retries, loops, or a quiet batch job. Treat spend like uptime.

Defaults that work

• Daily soft alert at 60% of budget
• Hard page at 90% with a named owner on rotation
• Stop-the-line: disable non-critical batch jobs above 95%

Owner note

Publish the alert channel and the “who replies after hours” roster in the same vault entry as the thresholds.
