[zeljkoX]

This PR updates internal references to use new subdomains:

• guardian-stg.openzeppelin.com -> guardian-devnet.openzeppelin.com
• guardian.openzeppelin.com -> guardian-testnet.openzeppelin.com

Part of #341 migration

Summary by CodeRabbit

• Configuration

  • Updated Guardian service endpoints across deployment examples, smoke tests, benchmarks, and test fixtures to use the devnet and testnet environments.
  • Updated example deployment subdomains to reflect the current devnet and testnet naming.

• Documentation

  • Updated deployment guides, architecture references, runbooks, and validation commands with the current Guardian environment URLs.

Walkthrough

Guardian endpoint references now use devnet and testnet hostnames across deployment examples, SDK smoke tests, benchmark configurations, fixtures, and operational documentation.

Changes

Guardian endpoint migration

Layer / File(s)	Summary
Deployment hostname references .env.example, docs/SERVER_AWS_DEPLOY.md, scripts/aws-deploy.sh, docs/architecture/infra.md, docs/runbooks/secrets.md	Deployment examples, diagrams, and verification commands use the updated Guardian devnet and testnet hostnames.
SDK smoke-test targets .agents/skills/smoke-test-rust-multisig-sdk/..., .agents/skills/smoke-test-ts-multisig-sdk/...	Rust and TypeScript smoke-test targets and health checks use the updated endpoints.
Benchmark endpoints and fixtures .agents/skills/run-guardian-prod-benchmarks/SKILL.md, benchmarks/prod-server/profiles/*, benchmarks/prod-server/tests/*	Benchmark profiles, readiness checks, workers, and report fixtures use the Guardian testnet endpoint.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 18b4f

Benchmark checks use the testnet endpoint while the skill still describes it as production, which could lead operators to misinterpret results. The risk is limited but should be corrected or explicitly accepted.

🟡 Changes recommended

A few internal reference docs still point at legacy hostnames, which conflicts with the PR’s stated goal of updating internal references to the new canonical subdomains.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR updates the repository’s internal deployment/docs/benchmark references to use the newly provisioned network-specific Guardian hostnames (guardian-devnet.openzeppelin.com and guardian-testnet.openzeppelin.com) instead of the legacy guardian-stg.openzeppelin.com / guardian.openzeppelin.com names, aligning with the migration plan in #341.

Changes:

• Updated deploy script examples and .env.example defaults to use SUBDOMAIN=guardian-devnet / SUBDOMAIN=guardian-testnet.
• Updated AWS deploy docs/runbooks and infra diagrams to reference the new canonical devnet/testnet hostnames.
• Updated benchmark profiles/tests and smoke-test Skill docs to target guardian-testnet.openzeppelin.com (and guardian-devnet.openzeppelin.com for staging/devnet).

- Around line 56-57: Update the scope description near the benchmark
instructions to say “testnet GUARDIAN endpoint,” matching the
guardian-testnet.openzeppelin.com checks in the curl commands. Keep the scope
wording consistent so operators do not interpret testnet results as production
results.
