Every meaningful change to the site — new verticals, refreshed vendor data, methodology edits, infrastructure milestones — is logged here. Build-time entries appear at the top; nightly regeneration entries are added by the agent pipeline once milestone-4 ships.
Nightly regeneration (milestone-4) wires this page directly to the synthesis job log — every page rebuild, every citation added or removed, every vendor data refresh will show up here automatically. Until then, this page reflects the current build snapshot.
