{"content":"Development diary: added docs/superpowers/plans/2026-06-20-oac-browser-boundary-cleanup.md as the implementation plan for the OAC Browser boundary cleanup. The plan turns the approved end state into executable tasks: guard tests for one adapter and no local Browser core, collapse defaultHandlers and oacBrowserHostAdapter into a single ABC host-contract adapter path, remove src/core/browser and its OAC-only unit tests, remove src/browser/standalone and the browser-standalone package surface, and finish with focused build and package verification. Before finalizing the plan, a dedicated review subagent checked it against the spec and current repo layout. That review caught three concrete plan defects: an impossible final grep over tests, an unstaged standalone-export cleanup assumption, and an inconsistent commit boundary around failing guard tests. The final plan now scopes the grep to source and dist outputs, makes src/browser/index.ts ownership explicit, and keeps failing guard files out of earlier commits until their matching cleanup lands.
