Summary

  • replace both obsolete per-series-file descriptions of Prometheus storage
  • describe the in-memory head and WAL separately from persisted block directories
  • link to the maintained on-disk layout documentation

Testing

  • focused assertions for removal of the stale claims and presence of the current layout terms
  • git diff --check

Site lint/build could not start locally because dependencies were absent and npm registry resolution was blocked; this draft relies on hosted CI for those gates.

Closes #1031.

The published figure trailed the live GitHub search by two merged PRs:
prometheus/docs#3053 (substantive) and hashgraph-online/awesome-ai-plugins#148
(listing), both merged 2026-08-26 into repos new to the set, so the repository
figure moves as well. Split is now 23 substantive / 12 accepted listings,
derived per-PR rather than incremented.
