Architecture Change to Workload

[parthshah1]

Summary

This PR delivers two major upgrades — a complete Go rewrite of the stress workload and a dedicated FilWizard container for smart contract deployment — plus a repo cleanup pass to make the codebase ready for external contributors.

---

Changes

1. Stress Engine — Full Go Rewrite (workload/)

The old shell-script + monolithic-Go workload has been replaced with a clean, modular Go stress engine.

Removed:

• workload/main.go — old monolithic driver
• workload/resources/ — all old Go packages (wallets, RPC, compute, consensus, mempool, miner, etc.)
• workload/main/ — all shell driver scripts
• workload/patches/synapse-sdk.patch, workload/entrypoint/setup-synapse.sh

Added (workload/cmd/stress-engine/):

• main.go — flat global state, Antithesis RNG-weighted action deck, multi-node connection management
• consensus_vectors.go — chain reorg and height increase assertions.
• evm_vectors.go — EVM/FVM contract interaction stress
• mempool_vectors.go — mempool spamming and gas-war scenarios
• reorg_vectors.go — deliberate reorg vector execution
• contracts.go — embedded contract bytecodes for on-chain deployment
• helpers.go — shared signing/nonce utilities

Added (workload/cmd/genesis-prep/):

• main.go — pre-funded wallet generation written to stress_keystore.json

Internal client (workload/internal/chain/client.go):

• JSON-RPC client for Lotus + Forest with JWT auth

The engine uses sigs.Sign() + MpoolPush() for local signing (no wallet API dependency), Antithesis SDK for reproducible randomness and liveness/safety assertions, and reads node config from STRESS_* env vars.

---

2. FilWizard — Dedicated Contract Deployment Container (filwizard/)

Contract deployment logic has been extracted from the workload entrypoint into its own container, keeping concerns separate and enabling the workload to start cleanly after contracts are deployed.

• filwizard/Dockerfile — multi-stage build: compiles the FilWizard binary, installs Foundry + abigen, pre-clones and compiles FOC contracts at image-build time for air-gapped operation
• filwizard/entrypoint.sh — orchestrates the full setup sequence: wait for chain → deploy FOC contracts → export contract addresses → generate Curio env → create/fund client wallet → mint USDFC tokens → register Curio SP → add SP to FWSS global whitelist → signal healthy
• filwizard/scripts/register-service-provider.js — ethers.js script: registers a Curio SP with all required PDP capability keys and 5 FIL fee
• filwizard/scripts/warm-add.js — ethers.js script: calls addApprovedProvider() (owner-only) on the FWSS contract
• filwizard/scripts/export-environment.sh — bash+jq script that reads deployments.json and writes a portable .env file

---

4. Repo Cleanup

Deleted:

• docker-compose2.yaml — stale alternate compose (no longer needed)
• workload/stress-engine — accidentally committed 38MB compiled binary

Fixed:

• docker-compose.yaml — corrected image tags (lotus:test → lotus:latest, workload:test → workload:latest); added profiles: ["foc"] to filwizard, curio, and yugabyte so the base protocol stack runs without them (make up) and the full FOC stack opts in (docker compose --profile foc up)
• Dockerfile — removed broken COPY docker-compose2.yaml and invalid COPY ../data; added COPY ./workload /workload
• Makefile — removed cd config && from up/down/logs/restart/cleanup (there is no config/ dir); added -include versions.env
• cleanup.sh — removed unnecessary sudo from rm -rf
• .env — removed 16 dead variable definitions for Lotus 2–4, Miner 2–4, and Forest 1–2 (none of these nodes exist in compose)
• build_push_filwizard.yml — fixed input name mismatch (workload_tag → filwizard_tag)
• run_antithesis_test.yml — added filwizard input parameter; added filwizard:* to all image strings (manual dispatch + all 4 scheduled runs)
• README.md — updated container count (9 base / 12 with --profile foc), removed stale docker exec workload CLI commands and workload/resources/config.json reference, added FilWizard to architecture, updated directory structure

Added:

• versions.env — version pinning file; change LOTUS_COMMIT, FOREST_COMMIT, etc. here and push a PR to test a new client version (will be wired into CI in a follow-up)

---

Test Plan

• make build-workload builds the workload image without errors
• make up starts the protocol stack without errors (no cd config failure)
• docker compose --profile foc up brings all 12 services healthy: drand → lotus → filwizard → curio → workload
• FilWizard container reaches /tmp/healthy and contract addresses appear in /shared/environment.env
• Stress engine connects to all nodes, begins action loop, and logs action names from the weighted deck
• Antithesis assert.Sometimes / assert.Always properties fire correctly during a test run
