Anti-FAMM Shadow Adversary

Purpose

Anti-FAMM is the adversarial dual of FAMM. FAMM records residuals, scars, torsion, failed routes, and coarsening agents. Anti-FAMM asks where FAMM failed to see the scar, over-scarred a valid route, or allowed a witness packet to pass while the invariant actually failed.

Anti-FAMM = the shadow map of FAMM blind spots.

Nullspace attack

Let \Pi(X) be the current FAMM witness projection and T(X) the dangerous target behavior: vorticity stretching, invariant failure, pair-address aliasing, closure instability, proof drift, or hidden residual.

Anti-FAMM searches for:

\eta\in\ker D\Pi_X

such that:

DT_X[\eta]\ne0

Meaning: the perturbation is invisible to the witness packet, but it changes the dangerous thing.

Shadow objective

\mathcal A_{\mathrm{FAMM}}(X)
=
\sup_{\eta\in\ker D\Pi_X,\;\|\eta\|\le1}
\|DT_X[\eta]\|

If \mathcal A_{\mathrm{FAMM}}(X)>\Theta_A, the witness packet is incomplete.

Classification attacks

False pass: FAMM says PASS, Anti-FAMM finds hidden residual or invariant failure.
False scar: FAMM says SCAR, Anti-FAMM finds the route was lawful under a missing witness.

Stack placement

candidate witness packet
→ FAMM classification
→ Anti-FAMM nullspace / shadow attack
→ Warden decision
→ promote / reopen / scar / coarsen / reject

Project sentence

Anti-FAMM is the shadow adversary for FAMM: it searches for perturbations invisible to the witness packet but active in the dangerous target behavior, forcing the Warden to reject, scar, coarsen, or upgrade incomplete routes before promotion.
