PostHog master-20261022-b904ac8-CE-ubuntu24.04-r3 build trail
How ReadyStack built readystack/posthog:master-20261022-b904ac8-CE-ubuntu24.04-r3 and its build kit, copied record by record: why the release exists, every chain, drive and stage it went through, the model work, the review rounds, the defects, the checks that verified it and when it was published. Each line names the record it comes from in brackets; a record that does not exist for this release says so.
