node_exporter flag tour with safe defaults
Recording rules vs alerts philosophy
Label naming workshop
Cardinality disaster on purpose
Recording rule for SLI starter kit
Dashboard critique rubric
Handoff doc for overnight teams

Outcomes you can show a lead

Explain cardinality tradeoffs to developers
Pick exporters that survive reboot storms
