Pins the production cold recovery key (rec-v1) in the SEPARATE recovery keyring, enabling identity-based node recovery to be verified offline. Private half lives only in Cloud KMS (key ring
pilot-recovery/recovery-authority, Ed25519, non-exportable), with signing locked to the sole custodian — distinct from the badge issuer key, preserving the two-key separation (a badge-key compromise can't forge a recovery).EGQ7…); still ldflags-overridable for rotation.Tests
TestPinnedRecoveryGoldenVector: a realgcloud kms asymmetric-signsignature over a canonical recovery statement verifies against the pin (baked-in vector, no KMS at test time).TestRecoveryKeyPinned: rec-v1 present, non-zero, and DISTINCT from the badge issuer key.go test -race ./...green (15 pkgs); gofmt clean. Replaces the obsolete placeholder test.
