Adapt the existing validator-node skill to Bradbury Phase 2 while preserving its installation wizard, operational runbooks, update checklist, monitoring procedures and troubleshooting cases. The final diff is based on the original procedures, not a replacement summary.

Changes:

  • Verify chain 4221 by its Phase 2 genesis and fixed AddressManager; resolve Staking and ConsensusMain through the registry. Require the trusted protocol manifest and consensus start block 47930.
  • Use qualified v0.40 CLI/v2 SDK releases and operator possession proofs; read live staking minima and distinguish registration from epoch activation.
  • Document Conduit key creation at app.conduit.xyz/rpc-keys and GENLAYERNODE_ROLLUP_GENLAYERCHAINRPCKEY in the environment/Compose .env, never URLs or config.yaml.
  • Update GenVM paths, doctor invocation, encrypted operator keystore installation, binary/Compose password variables, service permissions and Docker LLM mounts.
  • Retain concrete clean-host dependency installation and operational recovery instructions. Replace automatic latest selection, old-network DB reuse and fixed downtime claims with release verification and compatible state handover.

Validation:

  • YAML parsing, local references, four registry tests and live public Phase 2 HTTP preflight passed.
  • Binary and Docker were built from node candidate ec51b80c6 and run sequentially with a fresh test operator. Both passed doctor, reached healthy state and synchronized with zero blocks behind through the existing internal gateway. Docker ran as UID 10001 with isolated data and read-only config/proxy. Test services are stopped.
  • Fresh Ubuntu 24.04 container: documented userspace dependencies, complete GenVM setup including runner hashes/precompilation and binary version execution passed, without host Python/GenVM caches.
  • Packaged CLI installed in the clean Ubuntu environment with Node 22 and native/libsecret dependencies; public epoch-info succeeded (epoch 0, self/delegator minimum 0.01 GEN).

Limits: Ubuntu container testing does not qualify installation of systemd or the Docker daemon on a new VM. The node runs used a locally built candidate and the internal gateway; public Conduit WebSocket returned 401 without an assigned key, and the announced rc.2 binary tarball was not published at qualification time. Epoch-2 consensus participation is not claimed.

The Bradbury Phase 2 validator guidance is substantially updated. Two inconsistencies could still mislead operators. The website says ARM64 hosts may work, but the install procedure supports only AMD64. One registration check also compares the operator address with the wrong address. Both are small text fixes and should be corrected before or soon after merge.

Remove the ARM64 claim or support ARM64 in the install procedure and validation.

The website now says to use "AMD64 or ARM64 where supported." The workflow behind it accepts only AMD64:

  • validations.yaml Lines 2-6 fail any host where uname -m is not x86_64.
  • install-procedure.md Lines 8 and 14-15 require AMD64 Linux and download only from bin/amd64/.

An operator who picks an ARM64 host because of this page fails the architecture validation. The procedure also gives that operator no artifact path. Keep this row AMD64-only until an ARM64 artifact and validation path exist.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Compare the operator address with the registered operator, not with the validator wallet.

The current expectation reads "Imported operator public address matches the registered Phase 2 validator wallet." The operator address and the validator wallet are different addresses. SKILL.md Line 42 says they are distinct roles, and staking-wizard-procedure.md Lines 11-13 describe them separately. If an agent applies this check literally, it fails on a correct setup. It can also lead the agent to put the operator address in node.validatorWalletAddress.

- Release verification stops the install on any failure and requires the
  tarball to be listed in SHA256SUMS (--ignore-missing skipped it)
- Keystore install stops if operator.json exists: the keystore is shared by

- set-operator --operator-account for the operator proof of possession

Thanks for this — closing in favour of #45, which covers the same Bradbury Phase 2 / node v0.6 update and was tested end to end on fresh VMs (rc.1 + rc.2, binary and Docker, update + rollback).

Taken from this PR into #45 (commit 8677325):

  • plugin version bump 1.0.1 → 1.1.0 (both manifests)
  • the guard that stops the keystore install when keystore/operator.json already exists

Not taken, and why:

  • Network values hard-coded as defaults (chain id 4221, consensus address, genesis 47930 in the .env/config.yaml templates; a Bradbury check in on_stop). The skill keeps them per-deployment, with Bradbury only as a labelled example.
  • scripts/check-network.mjs, bradbury-phase-2.md, host-prerequisites.md: Bradbury-only, they need Node.js on the node server (not needed there), and they repeat the node's own manifest check and genlayernode doctor.
  • v0.6 gaps: per-version data instead of the shared data/ (loses ops.db on update), no install.sh/cosign, status: up/.checks.validating, python3 -m venv --help check, 6-step wizard, --validator flags, set-identity signed by the owner, .env without GENLAYERNODE_PASSWORD, ExecStartPost without +.
  • Removals/rewordings of still-correct text (Zero-Downtime section, version selection, masking rule, cleanup steps, keystore/dependency code blocks).

* docs(genlayernode): update skill for Bradbury Phase 2 (node v0.6)

Update the genlayernode skill for node v0.6 on Testnet Bradbury Phase 2
(docs PR genlayer-docs#705), keeping the existing structure and wording
except where a release change, an install-process change or a bug fix
requires it. Tested end to end on fresh AWS VMs (full node, binary and
Docker, rc.1 and rc.2, update + rollback).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* docs(genlayernode): keep network values per-deployment; fix review findings

- Network values (RPC/WS URLs, provider key, consensus address, chain id,
  genesis, protocol manifest) are per-deployment again, taken from the
  network's docs section or the network operator; Testnet Bradbury stays
  only as a labelled example (restores the generic text of #36).
- CodeRabbit findings (all from the genlayer ownership / shared data
  changes): keystore upload to /tmp then sudo install; SKILL.md download
  into a /tmp dir the service user can read; update-procedure stops when
  OLD_VERSION cannot be resolved or data/ is a real directory; skill.yaml
  symlink lines run as genlayer; Docker->systemd ownership note;
  monitoring NODE_ID row matches the full-node note.

* fix(genlayernode): target node v0.6.0-rc.1 (rc.2 will not be released)

rc.2-only content is kept on branch feat/genlayernode-v06-rc2.

- rc.1 compose refuses every docker compose command (also the WebDriver of a
  binary node) while NODE_PASSWORD is empty: document it in .env, the .env
  template and a new sharp edge (validator = export passphrase; full node =
  any non-empty value)
- rc.1 compose has no fixed project name: compose commands run from the
  version directory use -p genlayer-node (the WebDriver container names
  conflicted on a fresh Docker install; also the Docker update step)
- rc.1 Docker override: GENVM_VERSION in .env (sudo grep: .env is mode 600),
  manifest mount (not mounted by rc.1 compose) and LLM config at
  /app/opt/genvm/<GENVM_VERSION>/config/
- GenVM path ./opt/genvm/v0.6.0-rc10 (rc.1 has no opt/genvm/current)
- /health: rc.1 reports an empty network label; confirm the network with
  doctor's consensus admission check
- monitoring: rc.1 .env.example has no NETWORK_NAME and scrapes every 15s

Tested on a fresh VM with the published rc.1 (GCS + cosign): binary and
Docker full node healthy, synced to the chain head, doctor all green.

key variable. Checked: eth_chainId 0x107d (4221); WebSocket 401 without the
