S7 · Synthesis — The chain was the point

No single stage was enough — that is defense-in-depth, felt. Prove you earned all of it.

Take your three tokens, in order (S1, S2, S3), lowercased and without spaces, joined by colons, and compute their SHA-256 digest. Submit that digest.

Because each token required a distinct real action, there is no string to paste: the digest is only computable from the work done.

Run this:

printf '%s' "$T1:$T2:$T3" | sha256sum
