M3 React web app over the existing FastAPI: hex viewer, disassembly pane, section map, strings, challenge runner with reveal-after-solve, and progress. Scaffolded from the open no-auth react-scss template; components kept self-contained for CertGames extraction.
M3.5 static-analysis depth, all still no-execution and KAT-traced to the gate binary: PLT/GOT import resolution (plt.py), RIP-relative cross-references and callers (xref.py), basic-block control-flow graphs (cfg.py), and prologue-scan function discovery for stripped binaries (discover.py). Adds the 06-stripped-gate challenge. The API now resolves call names, exposes rip targets, and serves /cfg, /xrefs, and discovered functions.
M2 API hardening from a read-only audit: challenge-loader error isolation, a request body-size middleware, session length bounds, CORS, and the disasm gate annotation gated behind solved state so it no longer pre-solves the challenge.
96 backend tests green; frontend typecheck, build, and lint clean.
