feat(regulatory): seed-cross-source-signals.mjs — add REGULATORY_ACTION signal type #2494
Description
Context
Part of the Regulatory RSS pipeline. Depends on #2492 and #2493 (the seeder must be writing regulatory:actions:v1 before this is useful).
This is task 3/4.
What to change in scripts/seed-cross-source-signals.mjs
1. Add to SOURCE_KEYS array
'regulatory:actions:v1',2. Add to TYPE_CATEGORY map
CROSS_SOURCE_SIGNAL_TYPE_REGULATORY_ACTION: 'policy',3. Add to BASE_WEIGHT map
CROSS_SOURCE_SIGNAL_TYPE_REGULATORY_ACTION: 2.0,4. Add extractor function
function extractRegulatoryAction(d) {
const payload = d['regulatory:actions:v1'];
if (!payload) return [];
const cutoff = Date.now() - 48 * 3600 * 1000;
const recent = (payload.actions || [])
.filter(a => new Date(a.publishedAt).getTime() > cutoff && a.tier !== 'low');
if (recent.length === 0) return [];
return recent.slice(0, 3).map(a => {
const tierMult = a.tier === 'high' ? 1.5 : 1.0;
const score = BASE_WEIGHT['CROSS_SOURCE_SIGNAL_TYPE_REGULATORY_ACTION'] * tierMult;
return {
id: `regulatory:${a.id}`,
type: 'CROSS_SOURCE_SIGNAL_TYPE_REGULATORY_ACTION',
theater: 'Global Markets',
summary: `${a.agency}: ${a.title}`,
severity: scoreTier(score),
severityScore: score,
detectedAt: new Date(a.publishedAt).getTime(),
contributingTypes: [],
signalCount: 0,
};
});
}5. Add to extractors[] array
extractRegulatoryAction,Severity math
| Tier | Score | scoreTier() result |
|---|---|---|
high |
2.0 × 1.5 = 3.0 | HIGH |
medium |
2.0 × 1.0 = 2.0 | MEDIUM |
low |
filtered out | not emitted |
Composite escalation unlock
'policy' is a new category not currently in TYPE_CATEGORY. Adding it means REGULATORY_ACTION (policy) + VIX_SPIKE (financial) + COMMODITY_SHOCK (economic) = 3 distinct categories in Global Markets → detectCompositeEscalation() fires. This compound scenario (regulatory action during market stress + commodity dislocation) was previously invisible.
Acceptance criteria
regulatory:actions:v1appears inSOURCE_KEYSextractRegulatoryActionadded to extractor list- HIGH-tier actions produce severity
HIGHsignals - MEDIUM-tier actions produce severity
MEDIUMsignals - Missing key returns
[]gracefully - Composite escalation fires in Global Markets when policy + financial + economic categories co-fire
