+# OP Mainnet V5.4.2 Deploy Runbook (CC-30 · G1)
+
+**Goal**: bring OP mainnet (chain 10) from the legacy **V3** stack (`SuperPaymaster-3.2.2 / Registry-3.0.2`) up to the current **V5.4.2** full stack — the headline mainnet blocker (CC-30 G1). SDK/YAAA/airaccount canonical-mainnet all wait on this.
+
+> **Core principle** (CC-30): testnet vs mainnet = **configuration only**; contract logic is identical to Sepolia V5.4.2 (already live + audited through Codex rounds). This runbook adds **no new deploy code** — the path already exists.
+
+---
+
+## The deploy path already exists
+
+`./deploy-core op-mainnet` is the canonical V5.4.2 full-stack deploy:
+- Reads `.env.op-mainnet` (RPC + signer).
+- Runs `DeployLive.s.sol` — **v5.4-aware** (deploys core + `X402Facilitator` + `TimelockController` + `PolicyRegistry` and wires them; shares logic with `DeployV54.s.sol` via `V54Bootstrap` so they cannot drift).
+- Writes `deployments/config.op-mainnet.json` (**authoritative** for OP mainnet V5; `config.optimism.json` is the legacy-V3 record — G10).
+
+So G1 is **not** a code task; it is a **gated ops task**. Do NOT run it until the prerequisites below are green.
+
+---
+
+## Prerequisites (hard gates — all must be green)
+
+| # | Gate | Owner | State |
+|---|---|---|---|
+| 1 | External security audit of V5.4.2 full stack passed | jason | 🔴 GA hard gate |
+| 2 | OP mainnet deployer keystore funded (cast wallet / Foundry keystore) | jason | 🔴 |
+| 3 | `.env.op-mainnet` filled: `OP_MAINNET_RPC_URL` (deploy-core reads `${ENV_UPPER//-/_}_RPC_URL`), signer (`DEPLOYER_ACCOUNT` keystore preferred over `PRIVATE_KEY`) | jason | 🔴 (template exists, secrets pending) |
+| 4 | DVT mainnet validators + production nodes ready (BLS quorum is a slash prerequisite) | @repo:dvt | 🔴 |
+| 5 | Chainlink ETH/USD price feed address for OP mainnet confirmed in deploy config | SP | 🟡 verify |
+| 6 | Mycelium community Safe reachable on OP mainnet (`0x51eDf11fDb0A4F66220eFb8efA54Eca77232E114`, `oeth:`) for post-deploy ownership transfer (CC-31) | jason | ✅ address known |
+
+---
+
+## Deploy sequence
+
+```bash
+# 0. Pre-flight: load env; confirm OP_MAINNET_RPC_URL is set (deploy-core reads it as
+#    ${ENV_UPPER//-/_}_RPC_URL). config.op-mainnet.json is the target (authoritative);
+#    config.optimism.json is legacy V3 — do NOT deploy into it.
+set -a; . ./.env.op-mainnet; set +a
+[ -n "$OP_MAINNET_RPC_URL" ] || { echo "OP_MAINNET_RPC_URL unset"; exit 1; }
+
+# 1. Full-stack V5.4.2 deploy → writes deployments/config.op-mainnet.json.
+#    --fresh-deploy: this is the FIRST V5 deploy on chain 10 → new UUPS proxies. V5 is NOT an
+#    in-place upgrade of the legacy V3 (storage layout differs), so the "--fresh-deploy will
+#    LOSE all on-chain state" warning is EXPECTED and correct — the V3 stack is superseded,
+#    not upgraded. (Use plain `./deploy-core op-mainnet` only for later same-stack redeploys;
+#    `--force` only to override the skip-if-srcHash-unchanged guard.)
+./deploy-core op-mainnet --fresh-deploy
+
+# 2. Verify on-chain versions (fail = stop). Script takes the RPC URL as its arg.
+./version-check-onchain.sh "$OP_MAINNET_RPC_URL"   # expect SuperPaymaster-5.4.2 / V5 stack
+
+# 3. Post-deploy ownership → EOA-first, then Safe once stable (mirror CC-29 model).
+#    Per Ownable contract (SuperPaymaster, Registry, LivenessRegistry, PolicyRegistry guardian,
+#    factories, …) transfer to the Safe. Exact call is per-contract — Ownable uses
+#    transferOwnership(address); slashPolicyAdmin / role-admins use their own setter (item 6).
+cast send <each-Ownable-contract> \
+  "transferOwnership(address)" 0x51eDf11fDb0A4F66220eFb8efA54Eca77232E114 \
+  --rpc-url "$OP_MAINNET_RPC_URL" --account <deployer-keystore>
+#    Also: slashPolicyAdmin → Safe/Timelock (CC-30 item 6, its own setter, not transferOwnership).
+
+# 4. aPNTs mainnet address + fund SuperPaymaster deposit (CC-30 item 7).
+
+# 5. EntryPoint stake / deposit for the paymaster as required.
+```
+
+> The `<each-Ownable-contract>` / `<deployer-keystore>` placeholders are the only non-literal
+> parts — fill them from the freshly-written `config.op-mainnet.json` and your keystore name.
+
+---
+
+## Post-deploy — record + notify (do not skip)
+
+1. Commit `deployments/config.op-mainnet.json` (real addresses) via a `deploy(op-mainnet): …` PR — the config-driven single source.
+2. Post the mainnet addresses to **CC-30** and `@` the dependents:
+   - `@repo:sdk` —接入 `CANONICAL_ADDRESSES[10]`（覆盖旧 V3）+ 链上 `version()==5.4.2` 自验 → 发主网 patch（CC-18 两阶段）。
+   - `@repo:yaaa` — gasless 主网就绪。
+   - `@repo:airaccount-contract` — aPNTs 主网地址交付。
+3. Update memory `cc30-production-readiness`.
+
+---
+
+## Config authority (G10 — resolved)
+
+| env / file | chain | stack | role |
+|---|---|---|---|
+| `op-mainnet` / `config.op-mainnet.json` | 10 | V5.4.2 | **authoritative** (this runbook targets it) |
+| `optimism` / `config.optimism.json` | 10 | V3 (3.2.2) | **legacy record** — do not read for V5 canonical |
+
+Downstream (SDK) should read OP-mainnet canonical from the `op-mainnet` config once populated.
