 Open [the existing local preview](http://127.0.0.1:3000). It is already running; no terminal command is needed. The existing dispatch preview serves built `dist`. Current build08620a71 is from integrated43cb1baf. Historical core/mobile QA build6da89895 (an opaque artifact identifier, not a Git SHA) was produced from integrated unstableb1174163, including the cold-feed fix. HTTP200 and byte equality of served and built index were verified; runtime equality for final documentation descendants will be checked before handoff. Dispatch branch is area/dispatch. Final documentation landing SHA is reported in the owner handoff; runtime/build-input equality through QA closurec017069c was verified without rebuilding.

 # Resume brief: 2026-10-20 local review handoff
 
 Read PROGRAM, GOAL, QUALITY, LOCAL-REVIEW and newest RULE-CHANGES. Owner stopping milestone is "Ready for me to review and test locally" (relayed by interpreter). No optional work starts until owner review/confirmed actionable feedback. No push/deploy/spend/real cloud/account/peer/scheduler authority.
