observability/slo-lifecycle overview

Flagship end-to-end SLO practice for the observability specialization: kip recall of prior SLO/alerting memory -> service inventory -> parallel per-service SLI selection + SLO drafting -> cross-service error-budget policy -> adversarial SLO-design gate (EXECUTES budget math + measurement-query validation) -> slo-change-approval policy gate -> instrumentation plan -> collector/pipeline config -> adversarial telemetry gate (EXECUTES the pipeline dry-run/validate) -> telemetry-pipeline-deploy policy gate -> staged pipeline rollout with per-stage verification (release-lifecycle staged-verification pattern, sequential stages) -> alert noise audit -> parallel per-alert-family burn-rate redesign -> adversarial alert-tuning gate (EXECUTES rule validation + burn-rate simulation) -> alert-policy-change policy gate -> staged alert rollout (shadow canary -> paging-enabled full) -> error-budget review cadence -> kip assert of learned thresholds and outcomes.
