### Purpose and Functionality of SHHH

SHHH serves as a secrets sentinel that monitors communication logs to detect and redact sensitive information such as API keys, tokens, and passwords. Its primary purpose is to protect sensitive data from disclosure during logging or communication processes, ensuring that such information remains confidential and secure.

SHHH observes communication logs in real-time and enforces security policies by either disallowing the transmission of sensitive information or redacting it when necessary. This helps prevent accidental leaks of confidential data across the system, maintaining the integrity and security of communication channels within the infrastructure.

**Scope & Policy.** SHHH runs **inline** with channel logging and broker ingest, applying rules that deny or redact suspicious tokens (API keys, JWTs, passwords) **before** persistence or fan-out. This keeps cross-scope comms clean while preserving the audit trail.

# Interface Points

- **COOEE hooks:** redact at publish and at log-ingest.
    
- **WHOOSH channels:** enforce secret scrubbing across planning/implementation/review/testing streams.

## TODO

- Leader-only mode: Implement SHHH as privileged/elevated code paths under the CHORUS leader (similar to SLURP), protected by elections logic.
- Hooks: Add interceptors at COOEE publish/log-ingest and WHOOSH channels to detect/redact sensitive data.
- Rules: Provide detection/redaction rulesets with unit and integration tests; profile performance and false positives.
- Audit: Implement role-aware scrubbing policies and exception workflows with audit logs.
