{"content":"Agent Browser Core development journal — c41802a (feat: expose browser library to hosts). Added the read-only AgentBrowserLibrary host API for full retained Library snapshots, bookmarks, MRU browsing history, recent Bots, and recent URIs. Library items now include normalized URI/title/type/scheme, creation and visit timestamps, known visit counts, plus compact owner, proof, and source summaries while deliberately excluding full resolve envelopes and source.raw. Added parent-gated correlated postMessage reads for sandboxed/cross-origin hosts, history-changed and bookmarks-changed events, shared TypeScript types and request constants from both UI package entrypoints, legacy localStorage compatibility, and a detailed downstream integration/privacy guide. Verification completed under Node 22: full npm run verify passed 462/462 tests, package verification passed 5/5, targeted Library/Tab checks passed 33/33, and git diff --check passed. Work remains isolated on codex/browser-library-host-api; no release or production update was performed.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
