Detect Weber effect (enterohepatic recycling analog) — reporting rate spike following a regulatory action (label change, DHPC, safety communication). A label change that generates new reports creates a feedback loop where Excrete feeds back into Absorb.

## Agent metadata

- `idempotent`: true
- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
- `cost_tokens_estimate`: unknown

## Input schema

- `pre_action_rate` *number* (required) — Reports per quarter before regulatory action
- `post_action_rate` *number* (required) — Reports per quarter after regulatory action
- `action_type` *string* — Type of regulatory action: label_change, dhpc, dear_doctor, withdrawal, rems
- `quarters_since_action` *number* — Number of quarters since the regulatory action
