Captures the two open questions surfaced by PRD 0011: should bottles and agents stay grouped in one file or split per file, and should the format stay JSON or move to YAML / MD-with-frontmatter.
Recommends per-file MD-with-frontmatter (with agents shaped close to Claude Code's subagent spec so they can drop into ~/.claude/agents/ as a side effect), explicitly flags the PyYAML runtime dependency as a user-decision crossing the project's "low deps by default" line, and leaves several other choices (hidden dotdir vs visible, migration tooling) as open questions.
Companion to docs/prds/0011-cwd-manifest-trust-boundary.md (which solves the trust problem at the resolver layer); this doc explores a structural alternative that would make the boundary self-documenting on disk.
