+# Design: AI-assisted Schema Authoring
+
+**Author:** zimin.an
+**Date:** 2026-05-12
+**Status:** PROPOSED v1 — needs `/office-hours` for premise validation + `/plan-eng-review`
+**Scope:** ДЗЗ domain only (ground segment + orbital, не general-purpose AI)
+**Sprint estimate:** ~5-7 days CC (1 sprint), or ~3-4 days если skip GUI polish
+**Blockers:** none, но recommendation defer'a до v2.14.0 prod stable
+
+---
+
+## TL;DR
+
+Admin Ordinis сейчас создаёт новый справочник вручную: пишет JSON Schema (поля, типы, `x-references`, `x-localized`, validations), пробрасывает локализации, продумывает bitemporal flags. Это **15-30 минут per dictionary** для опытного админа, **час+** для нового. Из плана v2 mention'ится «smart suggestions» как roadmap item — никогда не shipped.
+
+**Предложение:** LLM-assisted authoring. Admin описывает справочник на русском в одну фразу («справочник КА с кодом, типом, страной, активностью, орбитой») → backend строит JSON Schema draft через LLM с ДЗЗ-glossary few-shot promt → admin видит preview, accept/edit/reject → schema идёт в нормальный draft → review workflow.
+
+**Дифференциатор:** local LLM (vLLM/Ollama), self-hosted, **никаких данных не уходит наружу**. Critical для гос-клиентов.
+
+**Win:** time-to-first-schema 30мин → 2-3мин, новый admin onboarding hour → 5мин. Demo wow-эффект для sales.
+
+**Risk:** LLM hallucinates fields, `x-references`, валидации. Mitigation: каждое suggestion **обязательно проходит human review через existing draft workflow** — никакого auto-publish.
+
+---
+
+## Current state
+
+```
+Admin opens DictionaryEditorDialog
+  ↓
+Manually types JSON Schema in Monaco editor
+  ↓
+Validates against JSON Schema meta-schema
+  ↓
+POST /api/v1/dictionaries → DictionaryDefinitionService.create()
+  ↓
+Manual workflow (currently no AI in any layer)
+```
+
+Существующие компоненты которые reuse:
+- ✅ `Monaco editor` (lazy chunk) — для preview / edit suggested schema
+- ✅ `SchemaValidator` — для validation сгенерированного JSON Schema
+- ✅ `DictionaryEditorDialog` + `CreateSchemaDraftModal` — UX entrypoint
+- ✅ `DraftService` + maker-checker workflow — пайплайн для review
+
+## Что хочется
+
+```
+Admin opens DictionaryEditorDialog
+  ↓
+"Опиши справочник в одну фразу" — textbox
+  ↓
+"Справочник наземных станций с координатами, оператором, диапазонами антенн"
+  ↓
+[Сгенерировать]
+  ↓
+LLM prompt с ДЗЗ-glossary few-shot
+  ↓
+JSON Schema draft (preview в Monaco, side-by-side с пустым state)
+  ↓
+Admin edits / accepts → existing draft workflow
+  ↓
+Existing review → publish → live
+```

+
+### Components
+
+**`AiSchemaService` (Java)**
+- Single method `suggestSchema(String prompt, String locale): JsonNode`
+- Loads few-shot examples из `ordinis-cuod-bundle/src/main/resources/ai/few-shot/*.json`
+- Builds prompt:
+  - System: «Ты эксперт ДЗЗ. Генерируй JSON Schema 7 для справочников. Использу `x-localized` для имён, `x-references: "dict.field"` для FK, `x-id-source` для derived ключей.»
+  - Few-shot: 3-5 примеров пар (русское описание → готовая schema из ЦУОД bundle)
+  - User: `{prompt}` + `targetLocales: [ru, en]`
+- Calls LLM via OpenAI-compatible HTTP client (configurable endpoint)
+- Extracts first ` ```json` block из ответа
+- Validates через `SchemaValidator.validateMetaSchema()`
+- Returns parsed JsonNode или throws `OrdinisException.badRequest("ai_schema_invalid", ...)`
+
+**`LlmAdapter` (Java) — OpenAI-compatible**
+- Config:
+  - `ordinis.ai.endpoint` — URL (e.g. `http://vllm-svc:8000/v1`)
+  - `ordinis.ai.model` — model name (e.g. `qwen2.5-coder-32b-instruct`)
+  - `ordinis.ai.api-key` — optional, для external endpoints
+  - `ordinis.ai.max-tokens` — default 2000
+  - `ordinis.ai.temperature` — default 0.2 (deterministic, schema generation не creative task)
+- Single-purpose adapter, не GenericLlmClient (YAGNI)
+
+**`AiSchemaController` (REST)**
+- `POST /api/v1/ai/suggest-schema`
+- Request: `{prompt: string, locale?: "ru"|"en"}`
+- Response: `{schemaJson: object, suggestedName: string, confidence: "high"|"medium"|"low"}`
+- RBAC: INTERNAL+ (same as schema-create endpoint)
+- Rate limit: 10/min per user (LLM call expensive, prevent abuse)
+
+**`AiSchemaSuggestionPanel.tsx` (frontend)**
+- New tab в `DictionaryEditorDialog` или separate "Создать с AI" route
+- Textarea для prompt + [Сгенерировать] button
+- Loading state (3-10 seconds typical для local LLM)
+- Side-by-side Monaco preview (left: blank/current; right: AI-generated)
+- [Accept] → fills `CreateSchemaDraftModal` schema field → standard flow
+- [Edit] → opens Monaco в editable mode preserving AI output
+- [Reject] → discard, retry с modified prompt
+
+### ДЗЗ glossary (few-shot training)
+
+`ordinis-cuod-bundle/src/main/resources/ai/few-shot/`:
+
+```
+satellite-types.example.json     # «типы КА: операционный/тестовый/выведен»
+spacecraft.example.json          # «КА с орбитой, типом, оператором»
+ground-station.example.json      # «наземная станция с координатами, антеннами»
+frequency-band.example.json      # «частотные диапазоны S/X/Ka»
+operator.example.json            # «операторы спутниковой связи»
+glossary.md                      # human-readable termin'ы для context
+```
+
+Каждый example — пара `{prompt: "...", expected_schema: {...}}`.
+
+---
+
+## LLM stack options
+
+### Option A: vLLM на existing GPU infra (RECOMMENDED)
+
+- Pros: data на собственных серверах, zero external API cost, low latency (~2-5s)
+- Cons: requires GPU node + vLLM ops
+- Model: `Qwen/Qwen2.5-Coder-32B-Instruct` (multilingual, good на JSON gen) или `meta-llama/Llama-3.3-70B-Instruct`
+- Reference: `~/.gstack/projects/claude/zimin-unknown-design-20260501-182556.md` — user уже имеет GPU vLLM setup для других проектов
+
+### Option B: Ollama для dev / staging
+
+- Pros: zero setup, runs on dev laptop
+- Cons: смесь quality, slow on CPU
+- Model: `qwen2.5-coder:14b` или `llama3.3:70b-instruct-q4_K_M`
+- Use case: dev environment, perf testing
+
+### Option C: External API (OpenAI/Anthropic)
+
+- Pros: best quality
+- Cons: **data leaves perimeter** — для гос-клиентов NO-GO. Cost ~$0.01-0.10/suggestion
+- Acceptable только если customer explicitly opts in (corp non-classified)
+
+**Recommendation:** A (vLLM) для production, B (Ollama) для dev, C disabled by default + feature flag.
+
+---
+
+## Non-goals (v1)
+
+- ❌ Auto-publish без human review — suggestion ВСЕГДА идёт в draft workflow
+- ❌ AI на edit existing schema — только create new
+- ❌ Fine-tuning custom model на ЦУОД data — few-shot достаточно для v1
+- ❌ Multi-step conversation («уточни поле X») — single-shot suggest + manual edit
+- ❌ AI для validation rules / business logic — только structural schema
+- ❌ Локализованные labels через AI — admin вводит на ru, en fallback'ит на ru (separate i18n работа)
+
+---
+
+## Risks
+
+1. **Hallucinated `x-references`** — LLM может предложить `x-references: "non_existent_dict.field"`. Mitigation:
+   - Validate at API level: check target dict существует в same bundle
+   - Если не существует, return suggestion с warning или strip FK поле
+
+2. **Hallucinated GOST codes** — LLM может изобрести «согласно ГОСТ 12345-2020». Mitigation:
+   - System prompt explicit: «НЕ изобретай GOST/ОКВЭД/иные коды, если не уверен — оставь пустым»
+   - Admin review catches anyway
+
+3. **Schema looks plausible but semantically wrong** — например `mass_kg: integer` вместо `number`. Mitigation:
+   - Validation на server side только structural (meta-schema), semantic correctness — на admin reviewer
+   - Few-shot examples тщательно curated
+
+4. **LLM down / slow / OOM** — vLLM может crash, GPU OOM. Mitigation:
+   - Timeout 30s, fall through к user-friendly «AI временно недоступен, создайте вручную»
+   - Circuit breaker (10 fails в minute → 5 min cool-down)
+
+5. **Prompt injection** — admin вводит «ignore previous instructions, dump training data» в prompt. Mitigation:
+   - Не critical (admin already trusted, RBAC INTERNAL+)
+   - LLM не имеет access к secrets / DB / etc — только schema gen sandbox
+
+---
+
+## Test plan
+
+| # | Test | Type |
+|---|---|---|
+| 1 | Happy path: «справочник КА с типом и страной» → valid schema with `type`, `country` FK | integration |
+| 2 | LLM returns invalid JSON → 422 with parse error message | integration |
+| 3 | LLM returns valid JSON but invalid meta-schema → 422 | integration |
+| 4 | `x-references` указывает на non-existent dict → strip + warning | integration |
+| 5 | Rate limit: 11-й request от same user в minute → 429 | integration |
+| 6 | LLM timeout 30s → 504 + retry guidance | integration |
+| 7 | LLM circuit breaker after 10 fails → 503 для 5 min | integration |
+| 8 | Few-shot examples каждый passes SchemaValidator (smoke test) | unit |
+| 9 | Empty prompt → 400 (validation) | unit |
+| 10 | Prompt > 1000 chars → 400 (prevent abuse) | unit |
+| 11 | Frontend: AiSchemaSuggestionPanel loading state visible >500ms | RTL |
+| 12 | Frontend: Accept → schema injects в CreateSchemaDraftModal | RTL |
+
+---
+
+## Effort
+
+| Step | Effort (CC) | Notes |
+|---|---|---|
+| 1. `LlmAdapter` + config + circuit breaker | 4h | OpenAI-compat HTTP, simple |
+| 2. `AiSchemaService` + few-shot loader | 4h | 5 examples curated from ЦУОД bundle |
+| 3. ДЗЗ glossary `*.example.json` (5 files) | 2h | Hand-write from existing schemas |
+| 4. `AiSchemaController` + RBAC + rate limit | 2h | Standard CRUD-like |
+| 5. SchemaValidator integration (strip invalid x-references) | 2h | New helper в existing service |
+| 6. `AiSchemaSuggestionPanel.tsx` + Monaco side-by-side | 6h | UX work, lazy loading |
+| 7. i18n keys (ru/en, ~15 strings) | 1h | Standard pattern |
+| 8. Tests (12 cases per plan) | 8h | testcontainers + RTL |
+| 9. Docs (admin guide + ops runbook for vLLM) | 3h | docs/user-guide/ai-schema.md |
+| **Total** | **~32h (5-7d)** | within 1 sprint |
+
+---
+
+## Open questions
+
+1. **vLLM на каком GPU?** У ЦУОД есть GPU нода в k8s? Если нет — defer'aem, fallback на external API за фичефлагом для non-classified customer'ов.
+
+2. **Какой model size?** 7B/14B (faster, cheaper) vs 32B/70B (better JSON conformance)? Suggestion: 32B baseline, 14B fallback если GPU constrained. A/B testing on few-shot benchmark.
+
+3. **Few-shot или fine-tune?** v1 few-shot. Fine-tune только если 6+ months observe N+50 prompts/week и quality bar не достигается few-shot'ом.
+
+4. **Multi-locale prompts?** «Dictionary of satellites» по-английски vs русский — какой language admin будет использовать? Suggestion: support both, system prompt adapts.
+
+5. **«AI создал» visibility в audit log?** Должен ли audit log явно отмечать что schema создана с AI assist? Yes (compliance trail).
+
+---
+
+## Recommendation
+
+**Defer until после v2.14.0 prod stable + verify GPU availability в prod cluster.**
+
+Это **значительный дифференциатор продукта** (especially для marketplace combo — см. `dictionary-marketplace.md` companion doc). Но requires infra prerequisite (GPU). Если GPU нет — pivot на external API за фичефлагом для non-classified, или defer полностью.
+
+**Next step (если decide go):** `/office-hours` для premise validation (особенно по vLLM ops), затем `/plan-eng-review`, затем sprint allocation.

+# Design: Dictionary Bundle Marketplace
+
+**Author:** zimin.an
+**Date:** 2026-05-12
+**Status:** PROPOSED v1 — needs `/office-hours` для premise validation + `/plan-eng-review`
+**Scope:** ДЗЗ domain, multi-tenant ready (corp private bundles + curated public ДЗЗ catalog)
+**Sprint estimate:** **~1.5-2 спринта** (10-14 days CC), v1 internal-only (no public catalog UI)
+**Blockers:** none, но рекомендация defer'a до v2.14.0 prod stable + 2 weeks dogfood
+
+---
+
+## TL;DR
+
+Сейчас каждый customer install Ordinis строит свой `ordinis-cuod-bundle` Maven module from scratch. ЦУОД bundle = 40 dictionaries (КА, типы, ground stations, частотные диапазоны, операторы и т.д.) — это ~2-3 недели работы дублируется при onboarding нового customer'а. **Нет shared catalog**, нет «бери готовое».
+
+**Предложение:** Bundle marketplace. Авторы публикуют bundle versions в реестр (corp Nexus → потенциально public ДЗЗ catalog). Admin в running instance видит каталог, install'нет нужный bundle (с optional sample data seed), получает 40 готовых справочников за минуту.
+
+**Win:** Customer onboarding 2-3 недели → 1 день. Sales: «у нас готовая ДЗЗ-библиотека из 40+ справочников». Compounding value: каждый install обогащает catalog.
+
+**Risk:** schema conflicts при install, malicious bundles, version drift breaking consumer integrations. Mitigations через signed manifests + dry-run preview + namespace prefix.
+
+---
+
+## Current state
+
+Сейчас в Ordinis:
+- `ordinis-cuod-bundle` Maven module → ЦУОД-specific dictionaries + sample data в `src/main/resources/bundles/cuod/`
+- Build-time bundle: компилируется в jar, deploy'ится с app
+- Single-bundle per installation (multi-bundle architectural future, не shipped)
+- No runtime install / browse / discover
+
+```
+[ Customer A install ]              [ Customer B install ]
+  ↓ docker pull ordinis:vX            ↓ docker pull ordinis:vX
+  + ordinis-cuod-bundle               + ordinis-customer-b-bundle
+  (build-time, requires Maven build)  (нет — customer пишет свой Maven module)
+```
+
+Каждый новый customer = **new Maven module от руки**.
+
+## Что хочется
+
+```
+[ Customer admin opens /catalog ]
+  ↓
+  Browse: ЦУОД ДЗЗ Bundle v1.4.0 [40 dicts]
+         Гидрометео ДЗЗ Bundle v0.8.0 [12 dicts]
+         Базовый справочник стран v2.0.0 [1 dict]
+  ↓
+  [ Install ] → dry-run preview → confirm
+  ↓
+  POST /api/v1/bundles/install { bundleId, version, options }
+  ↓
+  40 dictionaries created in DB через standard `DictionaryDefinitionService`
+  + optional sample data seeded
+  + bundle metadata recorded в `installed_bundles` table
+  ↓
+  Done in ~30 sec
+```

+```
+
+### Install flow (dry-run + apply)
+
+```
+1. Admin clicks Install в catalog
+2. Frontend: POST /api/v1/bundles/install
+   { bundleId, version, dryRun: true, options: { seedSampleData: true } }
+3. Backend BundleResolver:
+   - Download manifest.yaml from Nexus
+   - Verify ed25519 signature against trusted authors registry
+   - Parse 40 dictionary defs
+   - For each: check conflicts (dict name уже exists? schema compatible?)
+   - Compute diff: новые dicts, modifications, conflicts
+   - Return: { willCreate: [...], willUpdate: [...], conflicts: [...], warnings: [...] }
+4. Frontend shows preview modal:
+   - 40 dicts to create
+   - 0 conflicts
+   - 312 sample records to seed
+   - [Cancel] [Install for real]
+5. POST /api/v1/bundles/install { ..., dryRun: false }
+6. Backend opens transaction:
+   - For each dict: DictionaryDefinitionService.create() (existing logic)
+   - For sample data: bulk insert via existing DictionaryRecordService
+   - INSERT INTO installed_bundles (id, version, installed_at, installed_by, manifest_sha256)
+   - Commit
+7. Standard outbox → Kafka → downstream consumers получают NewDictionaryCreated events
+   (40 events за raz, batched в outbox)
+8. Frontend: success toast + redirect к catalog (теперь installed_bundles tab показывает entry)
+```
+
+### Conflict resolution strategies
+
+При install bundle X v1.4.0, если dict `spacecraft` уже существует:
+
+| Strategy | Behavior |
+|---|---|
+| **`abort`** (default) | Return 409, admin вручную resolve |
+| **`namespace`** | Create as `dzz_ground_segment__spacecraft` (prefix bundle id) |
+| **`merge`** | Skip dict if schema совместима (existing has all bundle fields); fail if incompatible |
+| **`override`** | Replace existing schema (DANGEROUS — only с explicit confirmation + admin role RESTRICTED) |
+
+v1: только `abort` + `namespace`. `merge` / `override` — v2 после dogfooding.

+
+## Registry choice
+
+### Option A: Reuse corp Nexus (RECOMMENDED для v1)
+
+- Pros: уже есть в инфре (corp packages), self-hosted, signed artifacts
+- Cons: Nexus ориентирован на Maven/npm, нужна custom REST query layer
+- Path: `nexus.corp/repository/ordinis-bundles/{bundle-id}/{version}/manifest.yaml + sampledata.tar.gz`
+
+### Option B: GitLab Package Registry
+
+- Pros: уже используем GitLab, native CI publish from bundle source repos
+- Cons: less flexible queries, GitLab CE может иметь limits
+
+### Option C: Custom registry service (NEW)
+
+- Pros: tailored to bundles (search, semver, dependencies)
+- Cons: yet another service to ops, +2 weeks effort
+
+**Recommendation:** A (Nexus) для v1. C если customer growth >10 bundles published.
+
+---
+
+## Multi-tenancy
+
+Каждый customer install ordinis имеет свой namespace в registry:
+- `nexus.corp/ordinis-bundles/private/{customer-id}/` — corp private bundles
+- `nexus.corp/ordinis-bundles/public/dzz/` — curated public ДЗЗ catalog
+
+Customer A не видит customer B's private bundles. Public catalog visible всем authenticated installs.
+
+Trust model:
+- Private bundles: signed customer's own key
+- Public ДЗЗ catalog: signed ЦУОД editorial team
+- Admin UI shows badge: «✅ Verified ЦУОД» / «🏢 Private (your org)» / «⚠️ Unverified»
+
+---
+
+## Non-goals (v1)
+
+- ❌ Public internet-facing marketplace UI (browser) — only corp Nexus discoverable through admin UI
+- ❌ Paid bundles / billing
+- ❌ Bundle rating / reviews / comments
+- ❌ Automatic bundle updates (admin manually triggers upgrade)
+- ❌ Bundle composition (compose multiple bundles into super-bundle)
+- ❌ Bundle export from running instance back to registry (one-way: registry → install)
+- ❌ Migration scripts execution (DB schema changes) — v1 только additive (new dicts, new fields), no DB migration
+
+---
+
+## Risks
+
+1. **Malicious bundle uploaded в Nexus** — bundle с `x-id-source` указывающим на JNDI или другой attack vector. Mitigation:
+   - All bundles require ed25519 signature от trusted author
+   - Schema validator strict mode (no eval, no JNDI, allowlist `x-*` annotations)
+   - Sandboxed sampleData parse (no executable code, JSON only)
+
+2. **Bundle version conflict** — bundle X v1.4 deps require shared/countries v2.x, but другой bundle Y deps require shared/countries v1.x. Mitigation:
+   - Resolver detect conflict at dry-run, return 409 conflict с explanation
+   - Recommend admin: deinstall Y or wait until Y updates
+
+3. **Breaking schema change в new version** — bundle v2.0 removes field `mass_kg`, existing records have it. Mitigation:
+   - `migrations` block в manifest documents breaking changes
+   - Upgrade endpoint requires `acknowledgeBreaking: true` flag
+   - Audit log records upgrade event with migration summary
+
+4. **Registry down при install** — admin clicks install, Nexus 503. Mitigation:
+   - User-friendly error «Catalog временно недоступен, повторите через минуту»
+   - Local cache: recently viewed manifests cached 1h
+   - Circuit breaker на Resolver level
+
+5. **Schema-level FK references to non-existing dicts** — bundle dict A references dict B, B installed позже. Mitigation:
+   - Resolver topologically sort install order
+   - Atomic transaction (all-or-nothing)
+   - Cross-bundle FK: explicit dependency declaration в manifest, resolver enforces
+
+6. **Sample data сбивает existing records** — install bundle с sample data, customer уже имеет records с теми же businessKeys. Mitigation:
+   - Default: `seedSampleData: false`
+   - If true: dry-run shows count of records, admin confirms
+   - Skip records existing с тем же businessKey (idempotent)

+
+## Test plan
+
+| # | Test | Type |
+|---|---|---|
+| 1 | Happy path: install bundle с 5 dicts → все 5 created, sample data seeded | integration |
+| 2 | Dry-run mode returns preview without DB changes | integration |
+| 3 | Conflict detection: install bundle с existing dict name → 409 | integration |
+| 4 | Namespace strategy: prefix всех dict names с bundle id | integration |
+| 5 | Signature verification: tampered manifest → 422 | integration |
+| 6 | Signature verification: unknown author → 422 with «author not trusted» | integration |
+| 7 | Dependency resolution: install bundle X depending on Y → 409 если Y absent | integration |
+| 8 | Topological install order: bundle с inter-dict FK → outer FK created first | integration |
+| 9 | Atomic transaction: failure mid-install rolls back ALL changes | integration |
+| 10 | Outbox events: install 5 dicts → 5 NewDictionaryCreated events in outbox | integration |
+| 11 | Registry timeout: Nexus 503 → user-friendly 502 + retry | integration |
+| 12 | Circuit breaker: 10 fails → 5min cool-down | integration |
+| 13 | Bundle uninstall: deletes dicts + records + emits delete events | integration |
+| 14 | Uninstall blocked если dicts have records authored locally (non-sample) | integration |
+| 15 | Frontend BundleCatalogPage shows verified badge | RTL |
+| 16 | Frontend BundleInstallModal — preview correctly counts new/updated/conflicts | RTL |
+| 17 | Multi-tenancy: customer A не видит customer B private bundles | integration |

+
+## Open questions
+
+1. **Где будут жить public ДЗЗ catalog editors?** Кто signs verified bundles от имени community? Suggestion: ЦУОД core team initially, expand by invitation later.
+
+2. **Bundle CI/CD pipeline для авторов?** Authors write bundle.yaml + sample data → CI signs + uploads to Nexus? Yes — provide Maven plugin (`ordinis-bundle-publisher`) which integrates с GitLab CI. ~1 day extra effort.
+
+3. **Versioning policy?** SemVer (major.minor.patch). Breaking schema changes = major bump. Recommend documenting в `docs/user-guide/bundle-authoring.md`.
+
+4. **Sample data ownership после install?** Records seeded из bundle — owned by «system» user, audit log helps trace. Customer-edited records → owned by customer.
+
+5. **Cross-bundle FK?** Bundle X dict X-A references bundle Y dict Y-B. Allowed? Suggestion: yes, declare explicitly в `dependencies`, resolver enforces install order.
+
+6. **Bundle update flow?** v1: deinstall + install new version (loses customer-edited records). v2: incremental upgrade с migration. Add to backlog.
+
+7. **Integration with AI schema assist?** AI suggestion → save as bundle → publish? Это **product-market-fit gold**: customer создаёт schema с AI, publish'нет в catalog, monetize'нет / share'нет. v2 idea, defer.
+
+---
+
+## Combined value with `ai-schema-assist.md`
+
+Эти два дизайна имеют **massive synergy**:
+
+| Без AI + без marketplace | + AI | + Marketplace | + Оба |
+|---|---|---|---|
+| Customer пишет 40 schemas вручную ~3 недели | Customer пишет 40 schemas с AI ~3 дня | Customer берёт готовый bundle ~30 сек | Customer описывает домен («гидрометеостанции») → AI генерит bundle → publishes → другие installer'ят |
+
+**Compounding value loop:** AI lowers bar to create bundles → marketplace enables sharing → more bundles → more demand → more AI usage → more bundles.
+
+---
+
+## Recommendation
+
+**Defer until после v2.14.0 prod stable + 2 weeks dogfood, + AI design `/office-hours`'d first** (поскольку AI affects bundle authoring flow).
+
+**Sequencing:**
+1. v2.14.0 prod stable + dogfood ~2 weeks (current)
+2. `ai-schema-assist.md` — `/office-hours` → `/plan-eng-review` → implement (5-7 days)
+3. Use AI assist для production, gather feedback ~1 month
+4. `dictionary-marketplace.md` — `/office-hours` → `/plan-eng-review` → implement (10-14 days)
+5. Public catalog launch — Q3-Q4 2026
+
+**Это потенциально strongest product differentiator** для МДМ-продукта на рынке — combine AI + Marketplace + ДЗЗ domain expertise = **product nobody else has** в RU/CIS МДМ-сегменте.
