ORCA fuses ISRO, INCOIS, DGLL and NOAA feeds into go/no-go guidance for Indian fishermen. The reasoning layer can be probabilistic; the safety policy cannot — every hard constraint is deterministic Python, so a refusal is reproducible and traceable to the data that caused it.
Causa answers the only hard question during an outage: which failure is the cause and which are downstream victims. It reconstructs the incident as dependency graphs, ranks the root-cause service with a confidence score and a plain-language why, then gates remediation behind a human and a canary.
welp diagnoses your last failed command from context the shell already had — exit code, toolchain state, config on disk. Rules, not guesses: no model call, no network, and small enough that the hook never makes your prompt feel slow.
