In this commit, we check in the artifacts of the first evolution
campaign. The champions directory holds the three GEPA-evolved routers,
all validated on sealed test sets and out-of-distribution corpora
against both the lnd production stack and the hand-written seed:
hb1 (hard-regime specialist), hb2 (superseded OOD sibling), and mx_c3
(the generalist with the best combined average). All are exploit-clean
and independently rediscovered a bimodal liquidity prior with per-edge
liquidity bounds in place of time-decayed penalties.
The lab directory is the running notebook: dated experiment writeups
(exp-001 through exp-007) covering the parameter-tuning null result, the
seed-beats-lnd baseline, the simulator integrity audit, the breakthrough
run, and the follow-up that produced the generalist, plus an ideas
backlog with the engineering learnings.
