Canonical record of the /plan-tune v1 design: typed question registry,
per-question explicit preferences, inline tune: feedback with user-origin
gate, dual-track profile (declared + inferred separately), and plain-English
inspection skill. Captures every decision with pros/cons, what's deferred to
v2 with explicit acceptance criteria, and what was rejected entirely.
Codex review drove a substantial scope rollback from the initial CEO
EXPANSION plan. 15+ legitimate findings (substrate claim was false without
a typed registry; E4/E6/clamp logical contradiction; profile poisoning
attack surface; LANDED preamble side effect; implementation order) shaped
the final shape.
