# Prometheus profile how-tos

- [Capture a metrics dump](capture-metrics-dump.md) — preserve exposition
  metadata, represent optional/runtime states, and keep label values private.
- [Build a source-derived synthetic fixture](build-synthetic-fixture.md) —
  cover source-defined optional surfaces with provenance, structural fidelity,
  and honest observed-versus-synthetic validation boundaries.
- [Metadata during iteration](../sqlite-metadata-reset.md) — distinguish live
  profile defects from inactive history; destructive reset boundary.
