Document blue/green deploy runbook for deploy.ts switch-green and rollback

[mikewheeleer]

Description

There is no operator runbook for the blue/green flow driven by src/deploy.ts and the npm run deploy:* scripts. Document the switch-green, rollback, and status procedures including health gating and the router on port 3000.

Requirements and context

• Document deploy:switch-green, deploy:rollback, deploy:status, and the blue (3001)/green (3002)/router (3000) topology.
• Include health-gate behavior, auto-rollback thresholds, and how to interpret deploy:status.
• Cross-reference health.ts readiness and shutdown.ts drain timing.
• Acceptance: runbook validated against actual command output; reviewed by an operator.

Suggested execution

• Fork the repo and create a branch:
  • git checkout -b docs/blue-green-runbook
• Implement changes:
  • docs/deploy.md
  • Tests: src/deploy.test.ts
  • Docs: docs/deploy.md
  • Include TSDoc/NatSpec-style doc comments
  • Validate security assumptions (input validation, auth, signature verification, secret redaction, idempotency)

Test and commit

• Run tests: npm test (coverage: npm run test:ci)
• Cover edge cases
• Include test output and security notes in the PR

Example commit message

docs(deploy): add blue/green operator runbook

Guidelines

• Minimum 95% line coverage on new/changed code
• No secrets in repo; use .env + deployment secrets only
• Clear documentation
• Timeframe: 96 hours from assignment
