Use this section when Chirp needs to prove the server-rendered UI is wired correctly before users see it: route contracts, htmx targets, OOB regions, Suspense blocks, SSE payloads, and debug tooling.
Debugging Swaps
chirp check, DevTools, debug headers, and swap failure modes
Diagnose broken htmx, OOB, Suspense, SSE, and boosted navigation updates.
Route Directory Contract
Reserved files, route metadata, sections, and shell contracts
Understand whatapp.check()validates for filesystem routes and app shells.
OOB Registry
Fail-loud region validation
Register shell regions and catch missing OOB blocks before users see empty swaps.
