CLAUDE.md was doing two jobs: durable repo conventions, and a ~500-line
phase-by-phase status narrative that duplicates the per-phase runbooks
and goes stale the moment a phase ships.
Keep mission, constraints, pinned stack, conventions, and "when in doubt"
in CLAUDE.md (572 -> 78 lines). Move the phase record verbatim to
docs/status.md, prefaced with a summary table and the known verification
gaps. Content is byte-identical; nothing was reworded or dropped.
Link both directions, and point the README's status section at the new
file.
