Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- Caddy's filter.ip_mask log filter module (caddy.logging.encoders.filter.ip_mask) masks IPv4 and IPv6 addresses according to configured CIDR subnet masks, supporting plain IP strings, host:port pairs, and comma-separated IP lists.
- The filter.ip_mask module is registered in the Caddy module registry under ID caddy.logging.encoders.filter.ip_mask and instantiates as *logging.IPMaskFilter implementing zapcore log field filtering with caddy.Provisioner.
- When integrated into Caddy's FilterEncoder under caddy.logging.encoders.filter, configuring a field with the ip_mask filter applies CIDR-based subnet masking to target IP log fields before JSON encoding.
