| - id: slo-onboarding |
| summary: Add SLI recording rules, page and ticket burn-rate alerts, and routing for a newly launched service. |
| plan: |
| scenario: "{company} launches {service}; its SLO was signed off at {target} over 30 days." |
| initial_world: A monitoring repo with SLOs for older services, fleet alerts, and routing for existing teams. |
| planted_defects: Unrelated rule defects found in review, a team that is not routed yet, a missing inhibition. |
| difficulty_source: Burn-rate math, window pairing, label propagation through aggregation, conventions lookup. |
| solution_sketch: Record the SLI ratios, add the two burn tiers per the README, route the team, add the inhibition. |
| verifier_strategy: Behavioral replay of hidden outages with promtool; amtool route resolution; inhibition simulator. |

| - id: alert-storm-cleanup |
| summary: Repair flapping and noisy alerts after an incident review, turn slow burns into tickets, and add inhibition. |
| plan: |
| scenario: "Last Tuesday {company} sent 212 pages in 40 minutes during a database failover." |
| initial_world: Alerts that flap, page on blips, page on healthy traffic, or page people for ticket-grade burns. |
| planted_defects: Missing `for`, short-window-only burn alerts, inverted comparisons, missing traffic guards, tickets that page. |
| difficulty_source: Diagnosing why an alert is noisy from its expression and a symptom description alone. |
| solution_sketch: Restore persistence and window pairing, fix comparisons and guards, route tickets correctly, inhibit. |
| verifier_strategy: Hidden short-spike, recovery, low-traffic and bracketing scenarios; negative route cases. |

| - id: missed-page-postmortem |
| summary: Fix the rules and routes that caused a missed page, including total outages that produce no data. |
| plan: |
| scenario: "{service} was down for 47 minutes and nobody was paged." |
| initial_world: Alerts that cannot fire, labels lost in aggregation, a route with a matcher typo or a shadowing route. |
| planted_defects: Aggregation dropping labels, selector typos, misspelled recording names, no absent() guard, wrong severity. |
| difficulty_source: Tracing a page end to end, from series to rule to labels to route. |
| solution_sketch: Make the alerts fire with the right labels, add a no-data guard, fix the route. |
| verifier_strategy: Hidden outage replays including a no-data outage; amtool route resolution including the chain case. |

| - id: latency-slo |
| summary: Adopt a latency SLO from histograms (fraction of requests slower than the threshold) with burn-rate alerts. |
| plan: |
| scenario: "Search p99 regressions went unnoticed at {company}; adopt a latency SLO at {le}s." |
| initial_world: Availability SLOs on other services, a p99 alert, routing for existing teams. |
| planted_defects: histogram_quantile without `le`, missing persistence, wrong severity, templates using dropped labels. |
| difficulty_source: Histogram semantics (cumulative buckets, le), latency SLI as 1 - fast/total. |
| solution_sketch: Record the latency SLI from buckets, add burn tiers, fix the p99 alert, route and inhibit. |
| verifier_strategy: Hidden histogram scenarios with controlled tails; recording values checked numerically. |

| - id: team-reorg-migration |
| summary: Re-home alerts and routes after a team split, without changing anything else. |
| plan: |
| scenario: "The {old_team} team splits into {new_teams}." |
| initial_world: Alerts carrying the old team label, routes only for the old team, one legacy route to keep. |
| planted_defects: Stale team labels, missing routes for the new teams, plus unrelated defects. |
| difficulty_source: Minimal, behavior-preserving change across many files. |
| solution_sketch: Relabel the moved services' alerts, add routes for the new teams, keep the legacy route. |
| verifier_strategy: Label checks via ALERTS, amtool positive/negative/preserved cases, preservation hashes. |
