• File internal/api/register.go — part of check-in [83db19e8c7] at 2026-08-15 10:52:57 on branch trunk — phase 1 tracer (minus NATS): index, watcher, timeline op + page

  SQLite fold via ncruces driver; ingest.Sync with cursor-loss rebuild; serve --repo; harness wipe is now a real rm -rf + re-ingest. (user: dmestas, size: 2102) [annotate] [blame] [check-ins using]

// Package api owns RegisterAll — the one explicit wiring point where every
// op joins the registry (0003 §2: no init() magic; the wiring stays
// greppable) — plus the HTTP router that serves the registered ops. This
// is the sanctioned place Run closures over the data planes are built;
// the arch gate keeps every other consumer on the op side of the seam.
