+// Free-tier recycle gate (Option B from FREE-TIER-RECYCLE-2026-05-12.md)
+//
+// The "wedge" of instanode is: an agent's very first POST /db/new (or any
+// /{service}/new) succeeds with zero auth and returns real credentials in
+// seconds. We MUST preserve that. The abuse surface this gate closes is the
+// *second* POST from the same fingerprint after the previous free-tier
+// resource expired — without this gate, that path returns a fresh 24h
+// anonymous resource forever, indefinitely. With this gate, the second
+// (recycle) POST is required to claim with email first; the user then falls
+// into the existing `free` tier in plans.yaml.
+//
+// Mechanics:
+//   - When an anonymous provision succeeds we SET recycle_seen:<fp> with a
+//     30-day TTL. (Set-after-success preserves the wedge — the first
+//     anonymous POST has no key, so it can never be gated.)
+//   - On every subsequent anonymous POST we read recycle_seen:<fp>. If it
+//     exists AND no active anonymous resource is present for the
+//     fingerprint, we return 402 free_tier_recycle_requires_claim with a
+//     claim URL. The customer claims with email and gets a JWT; the JWT
+//     bypasses the gate entirely (auth path skips this check).
+//   - 30 days is intentional: long enough that a recycler coming back
+//     "next week" is still gated, short enough that an accidental
+//     fingerprint hit (e.g. someone moved offices) decays on its own.
+//
+// Note: the spec lists worker/internal/jobs/expire.go as the trigger, but
+// setting the key on PROVISION instead of EXPIRY has identical semantics
+// (the key only matters when (a) it exists and (b) no active resource is
+// present — both conditions are reached the moment a previously-provisioned
+// anonymous resource ages out) and keeps the gate fully inside the api
+// module without cross-module coordination. This is the api-side
+// implementation of Option B.
