Architect drift review over 0ad8fc6..e4fb64d: the C12 amendment's words
match the shipped behaviour exactly (identity from the authored document,
run/mc closed-guards untouched, bound = overridable default; every
point-binding reload goes through the reopened probe). One medium item
fixed here: the unknown-axis test's rationale comment still described the
retired 'fully bound; nothing to sweep' refusal. Noted as low-priority
debt, unchanged: the four override-derivation helpers across the wrapped/
raw coordinate systems are candidates for consolidation when the next
family boundary appears.
