## Goal Reduce failed payments caused by gateway timeouts by 20%. ## Why it matters Customers whose payment times out at the gateway see "payment could not be completed, please retry" and often give up. Support-ticket themes in Lengo's memory point to timeouts as the main cause of failed payments. (All data in this project is synthetic.) ## How we will measure it | | | |---|---| | Goal metric | failure_rate | | Direction | decrease | | Target | 20% | | Guardrails that must not get worse | defaults from lengo.yml: http_5xx_rate, p95_latency_ms | ## Autonomy Preset from lengo.yml (Hands-off). ## Constraints No changes to the ledger, no new dependencies. --- _LengoAI picks this up because of the `lengo` label. Live smoke test, Run 1 profile._

    Gate a single back-off-with-jitter retry that carries an idempotency key behind goal_0001_gateway_retry, to cut failure_rate by 20% without repeating the 5xx retry storm from M-0002.

    Wired goal_0001_gateway_retry in release.py: flag on gives one back-off-with-jitter retry carrying an idempotency key; flag off is unchanged. Tests cover both flag states.

    Blocked: core-tests failed because a stale protected-path test asserts the default release wires nothing. A critical certifi vulnerability sits in protected lockfiles. policy-check, the build and the container scan did not run, so there is no image digest. The flag guard, both-state tests, size limits and secret scan are fine. No fix was committed.
