Establishes automated CI/CD workflows and bidirectional event communication across the Time Machines ecosystem repositories.

Workflows

CI (ci.yml)

• Trivy security scanning with SARIF upload
• Dependency review on PRs
• Agda build validation
• Markdown linting
• Dispatches web3ai-updated events to AI-Time-Machines and Time-Machines-Builders- on main branch success

Dependency Management (dependency-updates.yml)

• Weekly scheduled dependency updates
• Auto-detects package manager (npm/cargo)
• Creates labeled PRs automatically

Release Automation (release.yml)

• Triggers on version tags (v*)
• Generates changelog from commits
• Creates GitHub releases

Event Handler (repository-dispatch.yml)

• Receives events from ecosystem repositories: ai-time-machines-updated, time-machines-builders-updated, gatsby-blog-updated, transparency-logic-updated
• Creates issues on handler failures

Config Sync (cross-repo-sync.yml)

• Manual workflow for comparing configurations across repositories
• Generates sync analysis artifacts

Security

All workflows use explicit least-privilege permissions:

• CI: contents: read, security-events: write, pull-requests: read
• Dependency updates: contents: write, pull-requests: write
• Release: contents: write
• Event handler: contents: read, issues: write
• Config sync: contents: read

Repository Interconnection

Enable cross-repo notifications by adding REPO_ACCESS_TOKEN secret (Personal Access Token with repo scope). Without it, workflows run but skip notifications via continue-on-error: true.

Communication flow:

Web3AI (main push success)
  ├─> AI-Time-Machines (web3ai-updated)
  └─> Time-Machines-Builders- (web3ai-updated)
        └─> Can dispatch back to Web3AI
