An owner-capable `pty.openClient` had two ways to fail that looked like something else. If the relay still held an owner record but the request carried no matching resume proof, admission fell through to a *subscriber* grant — a success-shaped response the client cannot use, which it then rejected with "did not grant an authenticated PTY session owner". And if the relay no longer held the record the client named, admission threw a stale-recovery error, which the client answered by deleting its own recovery row and reopening: two round trips, and the deletion took the `clientInstanceId` with it. Admission now returns an explicit outcome. Every `session-owner` grant carries `resumed`, so a client learns in one round trip whether its checkpoints survived. A resume proof for a record the relay has forgotten is not an error — it mints a fresh claim with `resumed: false`. A held claim produces one of two coded refusals instead of a subscriber grant: `PTY_CONSUMER_OWNER_HELD_ATTACHED_ERROR` is blocked and exits retry at once, `PTY_CONSUMER_OWNER_HELD_DISCONNECTED_ERROR` is transient and retried under its own bounded budget, separate from the publication-pending one so a settling publication cannot spend it. Nothing here destroys state on suspicion. A refusal mutates no checkpoint, owner, migration, or persisted recovery state, and `resumed: false` voids only the checkpoints taken under the lease the relay just replaced — the recovery row and `clientInstanceId` survive, guarded so a losing attempt cannot void a winner's. Shortening a disconnected incumbent's grace to a 250ms floor is gated on positive proof: that record reaches 'disconnected' only from an observed transport close, expiring it transfers admission rather than stopping any remote PTY, and the incumbent's own matching proof still wins outright because it never reaches that branch. A duplicate `pty.openClient` on one connection is now rejected even when identical. Two responses settle their publications independently, so one shared admission cannot make one response's rollback and the other's commit atomic; recovery from an RPC timeout opens a new connection instead. An attached-holder refusal is converted to a typed `SshOwnerAdmissionBlockedError` and routed through the existing terminal relay-error callback rather than transport reconnect classification — the relay answered and refused on purpose, so redeploy backoff would spend its whole budget on a link that is working. Verified by mutation: reverting each behavior turns a named test red — vacant-resume grant (1), held-owner refusals (5), grace clamp (1), duplicate rejection (2), `resumed` validation (4), refusal-triggered row deletion (1), the losing-attempt guard (1), attached-holder retry (2), the split retry budgets (1), and the blocked-error routing (1). Negative tests assert live sessions survive: a resumed claim keeps its checkpoints, the incumbent reclaims its lease during the shortened floor, a newer owner's record is untouched by a stale attempt, and a blocked refusal removes no recovery state.
