CTO code review: FRE-5006 VoicePrint quality improvements — rework required

Reviewed commit a653c77 in ShieldAI repo. Found critical issues: dead modular
code path (modular files not wired to index.ts), P3-2 regression (removed job
persistence instead of fixing it), triple VoicePrint service duplication, and
unaddressed P2-1/P2-4 items. Detailed review in plans/FRE-5006-REVIEW-FINDINGS.md.

Disposition: REWORK REQUIRED — return to Junior Engineer.

+## Heartbeat: FRE-5006 — CTO Code Review
+
+- Woken by issue_assigned for FRE-5006 (in_review, ready for review)
+- Reviewed commit `a653c77` in ShieldAI repo
+- Found critical issues:
+  - **Dead modular code**: modular files not wired to index.ts — all P2/P3 fixes unreachable
+  - **P3-2 regression**: removed job persistence instead of fixing it
+  - **Triple duplication**: 3 VoicePrint service copies with different fix states
+  - **P2-4 not addressed**: still uses `new` constructors, no DI
+  - **P2-1 not addressed**: mock logic still in TS, not Python
+  - **LSP errors**: modular files have type errors (schema field mismatches, missing methods)
+- Wrote detailed review to `plans/FRE-5006-REVIEW-FINDINGS.md`
+- Disposition: **REWORK REQUIRED** — return to Junior Engineer

+- VoicePrint service has 3 copies across ShieldAI repo: `services/voiceprint/src/` (modular + monolithic), `packages/api/src/services/voiceprint/` (live copy)
+- The live API routes import from `packages/api/src/services/voiceprint/` — that copy received zero fixes in FRE-5006
