- new chapter 7, "Storage modes: durable and resident", covering what master gains with the databasev2 cherry-pick: durable: false for a RAM-only table, resident: keys for a table that outgrows RAM - states the parts a reader would otherwise hit as surprises: a keys-resident table is REFUSED at startup without WO_DATA, an update appends a delta rather than rewriting the row, and the chain is bounded at 16 links so a hot row does not degrade reads or replay - quotes the measured 2.55x smaller resident set, not an estimate - actors/deps/serving shift to ord 8/9/10; seeding is ord-driven so an existing WO_DATA keeps its rows and only a fresh boot reseeds - home card says a table can be RAM-only or outgrow RAM - two gate legs pin the new chapter; site-accept 23 checks, 0 failures Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> (cherry picked from commit 3b503c0db50aa737dd06ef6d17151c654a42c59b)
