P3-1: Replace envSchema.parse() with safeParse() + default fallback to
avoid module-level crash when env vars are missing.
P3-3: Add fs.existsSync check on ECAPA_TDNN_MODEL_PATH at startup
with warning log when model path is missing.
P3-4: Add Zod strict() mode to env schema to catch typos in env
var names (extra keys now produce validation errors).
P1-6: Confirmed resolved - voiceprint.service.ts already imports
VoiceEnrollment/VoiceAnalysis from @shieldai/db (consolidated package).
- S01 (High): Pre-compile regex patterns in RuleEngine.loadActiveRules() and
cache them; eliminate per-evaluation RegExp construction in rule-engine.ts
and spamshield.service.ts (ReDoS mitigation)
- S02 (High): SMS classifier now accepts optional senderPhoneNumber via
SmsClassificationContext; reputation check uses actual sender instead of
hardcoded 'placeholder'
- S03 (Medium): AlertServer (services/spamshield) now enforces JWT auth,
origin allowlist, and max client limit on WebSocket connections
- S04 (Medium): hashPhoneNumber() uses SHA-256 (crypto.createHash) instead
of reversible hex encoding (Buffer.toString('hex'))
- S05 (Medium): DecisionEngine.evaluate() wraps evaluation in Promise.race
with configurable evaluationTimeout; returns fallback decision on timeout
- S06 (Medium): CarrierFactory.getAllCarriers() is now async and properly
awaits isHealthy() promises instead of returning raw Promise objects

Security findings from April 30 review were claimed fixed but never committed.
Applied all remediations:
HIGH:
- WebhookHandler: fail fast when DARKWATCH_WEBHOOK_SECRET missing instead of defaulting to hardcoded secret
- field-encryption.service: require PII_ENCRYPTION_KEY at startup instead of defaulting
MEDIUM:
- WebhookHandler: make signature required (was optional, accepted unsigned events)
- WebhookHandler: reject unknown event types instead of silently defaulting to SCAN_TRIGGER
- scheduler.routes + webhook.routes: add ownership checks on /:userId endpoints (IDOR)
LOW:
- webhook.routes: generic error responses, full error logged server-side

- Create regex-validation utility with ReDoS detection (nested quantifiers,
overlapping alternations, complexity limits)
- Add @db.VarChar(500) constraint on pattern field in Prisma schema
- Integrate validation in rule-engine at load time and evaluation time

- Add runtime flag evaluation from FLAG_<KEY> environment variables
- Add enableCallAnalysis flag check to analyzeCall() and interceptCall()
- Add enableFeedbackLoop flag check to recordFeedback()
- Add 19 tests for feature flag behavior (checkFeatureFlag, getters, service integration)
- Add vitest config and test script to spamshield package
- Created decision-engine.constants.ts with all scoring weights, thresholds, and behavioral scores
- Updated decision-engine.ts to import and use constants instead of inline values
- All 12 hardcoded values now have named, documented constants
- Pre-existing type errors are unrelated to this change
- Implement CircuitBreaker class with CLOSED/OPEN/HALF_OPEN states
- Configurable failure threshold, success threshold, and timeout
- Fallback behavior when circuit opens (returns neutral 0.5 score)
- State change callbacks for monitoring and logging
- Comprehensive metrics tracking (executions, failures, successes, timestamps)
- Update SpamShieldService to use circuit breakers for both Hiya and Truecaller
- Add parallel API calls with graceful degradation
- Export circuit breaker types and service interfaces
- 32 unit tests covering circuit transitions, fallback, and service integration
