Две publicInstrument функции поддерживают одинаковую detail allowlist и nested brand.logoName policy. Текущего drift нет; один instruments boundary owner требует двух правок при изменении fields.
Expected Behavior
Одна stateless module-local projection обслуживает online и saved/enrichment callers без объединения execution models.
Evidence

Affected: catalog-discovery.service.ts:499–531; catalog-enrichment.service.ts:646–678.
Scope
In scope
Одна pure projection у existing instruments owner, два local imports.

## Problem

## Expected Behavior
Одна stateless module-local projection обслуживает online и saved/enrichment callers без объединения execution models.
## Evidence
Audit date `2026-10-11`; [03](https://git.personal.ksv741.ru/WealthLedger/main/src/commit/d07fbfabb1295780952a554185989d2d5b5c8349/audits/2026-10-11/reports/03-duplication-and-reusability-report.md). IDs DRY-002, TA-F15. Revision `0ad84ff4f0b4712abc7e69dc299856f14af6eadd`; Confidence High; Verification status static.
Affected: [catalog-discovery.service.ts:499–531](https://git.personal.ksv741.ru/WealthLedger/backend/src/commit/0ad84ff4f0b4712abc7e69dc299856f14af6eadd/src/modules/investments/instruments/application/catalog-discovery.service.ts#L499-L531); catalog-enrichment.service.ts:646–678.
## Scope
### In scope
Одна pure projection у existing instruments owner, два local imports.
### Out of scope
Nest mapper provider, generic/cross-repo mapper, whole catalog/enrichment merger, удаление privacy allowlist.
## Proposed Approach
Reuse одинаковые types/semantics; skinny discovery stored shape имеет другую роль и не включается.
## Acceptance Criteria
- [ ] Обе paths дают одинаковую approved share/bond projection при unknown/optional/null fields.
- [ ] Extra private fields и extra brand properties отсутствуют; UID guard/fetchedAt/CAS прежние.
- [ ] Нет нового DI/module/public API слоя; declaration одна.
## Verification
Existing instrument selection/whitelist HTTP/source cases, локальный semantic review; minimal targeted projection check только для observable trust boundary. Backend final gates.
## Dependencies
Нет; legacy producer deletion не требует сохранять его ради DRY.
## Traceability
