USR369 direction: codified the standard lookup order for answering any question (not just build tasks, which D-SEARCH-FIRST/D-LEARN-FIRST already cover) - 1) knowledge (memory-pipeline-api.php), 2) MD files (own gov/ + shared governance), 3) databases (records.db + own data/api.php), 4) internet (web_search/web_fetch/Exa, last resort). Added as its own law in RULES-REG.md right after D-LEARN-FIRST, matching that section format. Broadcast platform-wide (id 79).
