List the global public feed of peg state-transition alerts (all assets)

Consumer-facing calibration label, provisional | calibrated — the self-describing form of monitoring_only, in the SAME vocabulary the dispatcher puts on the webhook canonical event. provisional ⇔ monitoring_only=true.

Class-aware peg state. Mirrors the engine PegState enum and the peg_state Postgres enum. Used for state, from_state, and to_state fields across the API.

The state is CLASS-AWARE: an LST reading a −1.4% discount (normal unstaking spread) is PEGGED, while a fiat stable at far less would be DRIFT. Trust this value directly rather than imposing a naive discount cut.

True for a released monitoring_only (beta) asset — its calibration is provisional, so this alert should be read as experimental. Always present so public-ledger consumers can label beta rows.

Class-aware peg state. Mirrors the engine PegState enum and the peg_state Postgres enum. Used for state, from_state, and to_state fields across the API.

Signed discount (spread) captured at detection, as a rust_decimal string. Lets the /events feed show each transition's spread magnitude without a second per-row lookup. None for older rows where the alerts.discount column is NULL — the client falls back to the asset's live spread, so the field is additive (omitted, never null).

null until the dispatcher delivers this alert to its first fan-out target (Telegram or a webhook subscriber); stamped once at least one delivery succeeds. Stays null when the alert matched no subscriber — nothing was delivered — so a null here means "not delivered", NOT "delivery failed". Distinct from detected_at (when the engine saw the transition) and from on-chain commit (a separate evidence path).
