Complete passkey recovery transaction

 # Changelog
 
+## v0.1.0-preview.13 — 2026-09-03
+
+- Complete the password-plus-recovery-code flow with a short-lived restricted
+  grant bound into a replacement-passkey ceremony. Completion atomically
+  consumes the grant, stores the verified passkey, replaces every recovery
+  code, revokes any intervening sessions and ceremonies, and records both
+  audits without issuing a normal session.
+- Keep failed completion retryable until grant expiry: a duplicate credential
+  or other transaction failure rolls back grant consumption and recovery-code
+  replacement, while a mismatched WebAuthn binding consumes only the affected
+  ceremony.
+
+## v0.1.0-preview.12 — 2026-09-03
+
+- Add a root-local bootstrap transaction that creates the first passkey-only
+  application owner, non-personal organization, active membership, direct
+  owner binding, one-time enrollment digest, and secret-free audit records
+  atomically.
+- Fail closed and roll back the entire bootstrap when the application has not
+  seeded the configured owner role. The raw enrollment token is returned only
+  after commit and never enters repository state or audit records.
+
+## v0.1.0-preview.11 — 2026-09-03
+
+- Add expected-user completion for authenticated self-service passkey
+  enrollment. A mismatched ceremony is consumed and fails before credential
+  persistence, closing an authorization seam found while dogfooding Gamertan's
+  account security page.

 ## v0.1.0-preview.10 — 2026-09-03

+Administrator-assisted `authwebauthn.Recover` is deliberately host-local and

+and pending ceremonies, replaces prior enrollment tokens, appends a

+ceremony. The final passkey cannot be removed remotely.
+
+An account may separately expose self-service password-plus-recovery-code
+recovery through `authrecovery`. `Begin` verifies the password, consumes one
+printable code, revokes sessions, and returns a short-lived grant—not a normal
+session. Keep that grant in a narrowly scoped, Secure, HttpOnly, SameSite cookie
+and never place it in a URL. `BeginPasskey` binds its digest into the WebAuthn
+ceremony. `FinishPasskey` atomically consumes the grant, stores the verified
+replacement passkey, replaces the entire recovery-code set, revokes any
+sessions or ceremonies created during recovery, and returns the new plaintext
+codes exactly once. It does not issue a session; return the user to normal
+login after displaying and saving the new codes.
+
+A failed storage commit leaves the restricted grant available for a fresh
+ceremony until expiry. A binding mismatch consumes the mismatched ceremony.
+Applications must use generic failure responses and the same credential-attempt
+rate limiting as login.
 
 Before enabling production mutations, applications should require at least two
 independent passkeys and complete a local recovery drill.
