# Noise-based rule demotion — the pruning counterpart of evidence-based

> promotion. Disables mined flywheel:* rules that fire on decisions without ever being relevant (high noise ratio over a minimum sample)…

promotion. Disables mined `flywheel:*` rules that fire on decisions
without ever being relevant (high noise ratio over a minimum sample);
curated policy is flagged for an operator but never auto-disabled.

**Required scope:** `write`

### Request body

`DemoteNoisyRequest`

<ParamField body="dry_run" type="boolean">
  Preview only: report what WOULD be demoted without disabling anything.
</ParamField>

<ParamField body="min_noise_ratio" type="number (double)">
  Minimum noise ratio to qualify (default 0.9) — mostly noise.
</ParamField>

<ParamField body="min_sample" type="integer">
  Minimum total observations (cited + noise) before a rule is eligible (default 10) — never demote on thin evidence.
</ParamField>

<ParamField body="window_secs" type="integer (int64)">
  Analytics window in seconds (default 7d, cap 30d).
</ParamField>

### Response

`DemoteNoisyResponse`

<ResponseField name="demoted" type="DemotedRule[]" required>
  Mined `flywheel:*` rules disabled (reversible; re-enable via PATCH).

  <Expandable title="DemotedRule">
    <ResponseField name="noise_count" type="integer" required />

    <ResponseField name="noise_ratio" type="number (double)" required />

    <ResponseField name="rule" type="string" required />

    <ResponseField name="rule_id" type="string" required />
  </Expandable>
</ResponseField>

<ResponseField name="dry_run" type="boolean" required />

<ResponseField name="evaluated" type="integer" required>
  Rules that met the threshold (auto + curated).
</ResponseField>

<ResponseField name="flagged_curated" type="DemotionCandidate[]" required>
  Curated/user rules that met the noise threshold but were NOT touched — an operator must review these; the system never auto-disables policy.

  <Expandable title="DemotionCandidate">
    <ResponseField name="auto_demotable" type="boolean" required>
      True for mined `flywheel:*` rules (safe to auto-disable); false for curated/user policy (flagged for an operator, never auto-disabled).
    </ResponseField>

    <ResponseField name="cited_count" type="integer" required />

    <ResponseField name="noise_count" type="integer" required />

    <ResponseField name="noise_ratio" type="number (double)" required>
      `noise / (cited + noise)` at selection time.
    </ResponseField>

    <ResponseField name="rule" type="string" required />
  </Expandable>
</ResponseField>
