Partitions Plan B's remaining phases (3-8) across three cycle-2 streams
once cycle-1 Stream A and Stream B's bundled Phase 1+2 PR have merged.
Stream A picks up Phase 3 (prompt_or_flag + builder compression),
Stream B owns Phases 4/5/6 (after_manifest_change, ParamsFile, batched
purge), Stream C owns Phases 7/8 (parser migration to relicario-core +
WASM exports). Plan C (extension restructure) is not in cycle 2.
Each kickoff bakes in cycle-1 lessons: prefer single-line relay body
content, avoid the f-string footgun in Python inbox-monitor scripts,
narration discipline (IN-PROGRESS updates at meaningful in-flight
moments, not just phase boundaries). The PM prompt also captures
cycle-1 outcomes (commits/PRs landed, the 17 pre-existing extension
test failures pattern, DEV-B's option-(b) git_run choice) so the new
PM picks up cold without relay history.
