Operational signal catalog
Bounded observability signals for payment operations: webhook recency, checkpoint lag, exception depth, drift, provider latency, payout backlog.
01
Purpose
Use this catalog when designing observability for crypto payment operations. Signals are qualitative patterns—you define thresholds, dashboards, and alerts internally.
02
Signal definitions
Each signal maps to incident classes and playbooks via /incidents routing.
Six core operational signals (bounded definitions).
| Signal | Measures | Investigate when | Typical owner |
|---|---|---|---|
| Webhook recency | Time since last verified webhook processed | Grows while activity continues; post-deploy spikes | Integration / SRE |
| Checkpoint lag | Time between lifecycle checkpoints | Stalls exceed rail/policy expectations | Payment operations |
| Exception queue depth | Open taxonomy-owned exceptions | Monotonic growth; aging beyond internal targets | Operations / finance |
| Reconciliation drift | Persistent three-plane mismatch | Repeat matcher failures for same payment_id | Finance reconciliation |
| Provider latency | API latency/errors at integration boundary | Timeouts block status reads; retry storms | Integration engineering |
| Payout review backlog | Withdrawals awaiting treasury review | Growth during settlement incidents; eligibility failures | Treasury / finance |

Signal → action
Degrading signals do not imply a single root cause. Classify incident class, then route: /incidents for the matrix, payment incident triage when unclear.
- Retries are normal. Webhook delivery is at-least-once. Design consumers to tolerate duplicates and out-of-order arrivals where possible.
- Asynchronous by design. Payers, chains, and your servers operate on different clocks. UI and finance should not assume synchronous finality.
- Eventual consistency. API reads, webhooks, and portal views may briefly diverge during transitions. Reconciliation jobs exist to converge truth.
