Changelog ​

Dated record of material changes — plan closures, architectural shifts, and significant doc-level edits. Each entry links to the now-current pages so this list stays a navigation surface, not a mirror of the docs.

The guide and decisions pages describe the current state. This page describes how we got here. When old design context is useful (a "before/after" diagram, a trade-off that was considered and rejected), it lives in the changelog entry, not in the current-state docs.

Convention: one Markdown file per entry, named YYYY-MM-DD-short-slug.md. Entries listed below newest-first.

  • Silent infrastructure failure made unrepresentable — the bots-leaving-tables mystery was a 16-day unalerted litellm outage; the Dash0 pack proved blind AND unrouted since July (no rule-fired Slack message ever sent); routed pack live on stg+prd with fail-closed parity (check:dash0-rules) + drills, Fly networking doctrine page + check:fly-urls, HAS continuous litellm heartbeat.
