This page is a HexDocs-packaged pointer for the Nyquist-style 41–44 posture grid. It does not duplicate the full table.
Canonical source
The authoritative matrix (all rows, ref: block, reopen triggers, and links to phase VERIFICATION / VALIDATION paths) lives in the repository at:
.planning/nyquist-phases-41-44-matrix.md on GitHub.
That path is not part of the Hex package tarball; clone the repo or use the link above. If anything here or in MAINTAINING.md disagrees with that file, the .planning/ matrix wins (see MAINTAINING.md § Nyquist policy).
