Wires the existing mix_lez_chat simulation to drive the gifter's
EIP-191 allowlist auth path end-to-end:
* bumps vendor/nwaku and vendor/logos-lez-rln (and, transitively,
logos-delivery-module and its bundled logos-delivery copy) to pick up
the auth plugin, the auto-registering client's EIP-191 signing, and
the new --mix-gifter-allowlist / --mix-gifter-auth-key CLI flags.
* adds a `gifterAuthKey` knob on WakuConfig + the JSON config bridge in
client_api so chat sender/receiver instances sign their gifter
requests too.
* commits 5 fixed test secp256k1 keys (one per non-gifter mix node and
per chat client) under simulations/mix_lez_chat/fixtures/gifter_auth/
along with their derived addresses.
* run_simulation.sh sources keys.env+addresses.env, sets
`mixGifterAllowlist` on mix node 0, and threads the matching
`mixGifterAuthKey` / `gifterAuthKey` into nodes 1-3 and the
receiver/sender configs.
Test fixtures only — keys must never be reused outside this sim.
TREE_ID_HEX updated from 24 to 32 bytes to match SPEL's tree_id format,
fixing stale payment account lookup that caused silent registration
failures (KeyNotFound error 8).
setup_and_run.sh now restores working tree files in all nested
submodules after git submodule update --init, which resets them.
Multi-stage Dockerfile pre-builds all heavy nix dependencies. Runtime
image (~8.5GB) at ghcr.io/adklempner/logos-chat-sim:latest includes
nix store closure + Rust + cargo-risczero/r0vm + system clang.
run_in_docker.sh pulls from GHCR, symlinks pre-built modules, builds
sequencer + run_setup from source (~10 min per run).
Update vendor/logos-lez-rln to a591645 (rebased onto main with
member-expiry merged, single squashed commit).
Add INSTRUCTIONS.md with macOS, Linux (native), and Docker instructions.
