CLAUDE.md gains the five undocumented subsystems (env-branches ladder +
EnvSyncEngine, Telegram bridge, possibilities matrix, collision map,
PR labeler) and their flags; docs/map and the pr-creation workflow now
describe head/prod ladder resolution instead of single default_branch;
CHANGELOG's [Unreleased] covers all sixteen merged PRs plus this
hardening basket.
