Struct NudgeCounterState 

struct NudgeCounterState {
    registration_nonce: u64,
    block_id: String,
    count: u32,
    last_nudge_at_ms: u64,
}

Per-target-agent consecutive-nudge tracking for the Warden Supervisor guardrail. Keyed on the target agent’s lowercased name in Handler::nudge_counters.

Fields

registration_nonce: u64

The target’s AgentRegistration::registration_nonce as of the last nudge — a respawn (new nonce) resets the counter, since “consecutive” only makes sense within one continuous run. Real nonces are ≥ 1 (persistent-controller spawns only — persistent::next_registration_ nonce); PTY/shell and HTTP-register paths always register with 0 (“not recorded”), so nonce alone can’t detect a respawn for them — block_id below covers that case instead.

block_id: String

The target’s block id as of the last nudge. A PTY/shell-registered agent that’s closed and relaunched gets a fresh block id (a new pane), which nonce (always 0 for these paths) can’t see — comparing block_id catches that respawn case reagent flagged as a P1 gap (nonce-only reset never fires for PTY agents). Doesn’t help detect a respawn that reuses the same pane/block id (e.g. a one-shot SubprocessController that re-registers every turn in-place) — that case still relies on NUDGE_COOLDOWN_RESET_MS alone, same as before.
