agent/redact.py snapshots _REDACT_ENABLED from HERMES_REDACT_SECRETS at
module-import time. hermes_cli/main.py calls setup_logging() early, which
transitively imports agent.redact — BEFORE any config bridge has run. So
users who set 'security.redact_secrets: false' in config.yaml (instead of
HERMES_REDACT_SECRETS=false in .env) had the toggle silently ignored in
both 'hermes chat' and 'hermes gateway run'.
Bridge config.yaml -> env var in hermes_cli/main.py BEFORE setup_logging.
.env still wins (only set env when unset) — config.yaml is the fallback.
Regression tests in tests/hermes_cli/test_redact_config_bridge.py spawn
fresh subprocesses to verify:
- redact_secrets: false in config.yaml disables redaction
- default (key absent) leaves redaction enabled
- .env HERMES_REDACT_SECRETS=true overrides config.yaml
