Struct ResilienceConfig 

pub struct ResilienceConfig {
    pub on_upstream_error: FailMode,
    pub on_internal_error: FailMode,
    pub on_config_error: FailMode,
    pub on_parser_limit: FailMode,
    pub upstream_timeout_ms: u64,
}

Explicit, per-scenario failure policy. No single global boolean: each kind of trouble has its own correct posture (see the defaults’ rationale in §9).

Fields

on_upstream_error: FailMode

Origin unreachable / timeout. fail_closed → 502, fail_open → 503 (retryable). NB: fail_open here does NOT mean “let traffic through” (there is no origin to reach) — only which 5xx is returned.

on_internal_error: FailMode

Module panic / regex blow-up. fail_open → skip the module and continue (a WAF bug must not take down the site); fail_closed → synthetic block.

on_config_error: FailMode

Invalid config detected at runtime (hot reload, Pillar 3). fail_open → keep last-good config; fail_closed → refuse serving until valid.

on_parser_limit: FailMode

Normalization failed (limits exceeded / malformed input). fail_closed → 400; fail_open → forward UNINSPECTED (logged loudly).

upstream_timeout_ms: u64

Hard cap on the upstream round-trip so a stalled origin cannot pin the worker. Must be >= 1 (validated).
