Track anonymous website and download events

[yaacovcorcos]

Summary

• add privacy-preserving first-party tracking for page views and outbound links
• route installer clicks through validated ScientFactory redirects and record click or resolution failure events
• store the four whitelisted event types in Cloudflare D1 without cookies, IPs, fingerprints, referrers, or persistent visitor IDs
• add an operator report command, migration, privacy disclosure, and endpoint coverage

Validation

• bun run check
• local Cloudflare Pages function flow verified
• all four installer links resolve to same-site tracked endpoints
• local and preview hosts confirmed not to write production events

Deployment impact

• D1 database scientfactory-downloads and migration 0001_event_tracking.sql are already applied.
• Production uses the DOWNLOAD_DB binding from wrangler.jsonc.
• A tracking database failure is fail-open and never blocks a valid installer redirect.
• download_failed means ScientFactory could not resolve or start the redirect; it does not claim to observe a later GitHub transfer failure.
