session-learnings-reference-tier-is-prime-pruning-candidate

Entries tagged [REFERENCE] in session-learnings.md that are re-discoverable from API docs or first principles in under 2 minutes don’t compound intelligence — they just add bulk. 9 such entries were pruned in this session (API tier endpoints, built-in Claude features, tool documentation facts, disaster recovery derivable from repo READMEs). Prune aggressively; CRITICAL and OPERATIONAL entries that change diagnostic or behavioral patterns should be kept.
