How It Works

PBS modules hook into 7 stages — `entrypoint` through `auction-response` — each with richer data. `device-enrichment` hooks early, injecting signals before bidders. Stages fire in declaration, not registration order. See {11} for enrichment, {13} for filtering.

Field Notes

  • Hook method typo = silent no-op; zero error logging
  • `Init` fires once at startup; `Entrypoint` per-request
  • Rejection silently ignored at last 2 stages (by design)
