 ## Status and scope
 
-This document describes the intended architecture for the rebuilt AI Platform, not a verified description of working code. The root Lead Scoring provider specification is `docs/specs/ai-platform-lead-scoring.md`; it remains `draft/review_ready` pending review. Its ownership boundary is authoritative only after approval. The archived code and documents under `old_repo/` are historical evidence, not the new architecture or implementation.
+This document records boundaries for the approved AI Platform rebuild and app-auth baseline `omni-ai-platform-app-auth` revision 2.

The archived code and documents under `old_repo/` are historical evidence, not the new architecture or implementation.
 
 AI Platform is a provider service: it executes bounded rule scoring and a selected AI profile, maintains scoring-run lifecycle, and exposes result retrieval. DotB-Omni owns customer-configured rules/weights, HITL and customer actions, snapshot construction, user authorization, and CRM writeback. Omni is notified of terminal outcome through an agreed signed HMAC webhook and then calls the authenticated GET endpoint for run details. DotB EMS remains the CRM system of record. There is no customer-facing settings or review UI in this service scope.

 - **Lead Scoring domain:** rule execution, scoring-run state/invariants, and profile semantics. Deterministic scoring rules should be pure functions; run identity and lifecycle belong in an entity/value model where useful.
 - **Lead Scoring application:** admission, idempotency, execution coordination, result retrieval, and notification workflow. Use cases own transaction meaning; infrastructure supplies mechanisms. Its versioned AI profile selects AIHub or OpenAI-compatible for the service and contains model, prompts and timeout; OpenAI-compatible URL is also versioned, while API key stays in server settings. App-provided rules and weights arrive in each run body. Bootstrap constructs the AIHub adapter and an OpenAI-compatible adapter for the URL captured in the run's profile; raw V-Key is forwarded only for AIHub.
 - **Infrastructure:** database mappings/repositories, separate AIHub and OpenAI-compatible HTTP adapters, HMAC signing, and delivery adapters. Provider details stop at these boundaries.
-- **Presentation:** HTTP request/response mapping, tenant-auth dependency at the edge, health/readiness, and API error mapping. Transport schemas do not become domain objects by accident.

 Dependency direction is inward: presentation and infrastructure may depend on application/domain contracts; domain does not depend on frameworks, persistence, network, environment, or application orchestration. Bootstrap is the composition root. Avoid generic base services, empty ports, service locators, and multiple deployment processes unless evidence requires them.

 ## Domain terms
 
-- **Tenant:** customer/account boundary used to scope credentials, idempotency keys, and run access. A run lookup must remain inside its authenticated tenant.
+- **App / installation:** one Omni deployment/environment with a stable `app_id`; one backend API key shared by its accounts. Provider checks active state and the simple Lead Scoring permission, and stores only a verifier. Rotation keeps run ownership. Admin Web uses an independent session; issuance/rotation is operator CLI only.
-- **Tenant key:** service credential used to authenticate a tenant/caller at the provider boundary, subject to final agreed provisioning contract. It is distinct from the raw **V-Key** used for AIHub access. Do not treat the terms as interchangeable.
+- **Account:** Omni workspace identified by `account_id` in the request. Omni owns user/account/EMS authorization; AI Platform does not register accounts. `(app_id, account_id)` distinguishes workspaces across installations.
 - **V-Key:** sensitive AIHub credential material. Target rule: keep raw value in memory only for the active execution attempt; never persist, log, trace, or send it to the browser. Source and exact forwarding protocol are unresolved.
 - **Canonical snapshot:** bounded input assembled by Omni from the lead and permitted evidence. It is an input snapshot, not an AI Platform-owned CRM record.
 - **Scoring configuration:** customer-authored rule/weight and HITL configuration owned by Omni. The provider may consume an immutable version with the request for reproducibility; it does not become the customer configuration authority.
 - **AI profile:** `light`, `medium`, or `heavy` in an Omni request denotes the bounded orchestration mode. Separately, the internal versioned Lead Scoring configuration selects the provider, model, prompt and timeout; each run freezes its version. Provider choice is not an Omni request field. Concrete models and AIHub behavior still require verification.
-- **Scoring run:** one provider execution for one tenant, request UUID, subject, snapshot, configuration version, and AI profile. The server-generated run UUID identifies the persisted run.
+- **Scoring run:** one provider execution for one app/account context, request UUID, subject, snapshot, configuration version, and AI profile. The server-generated run UUID identifies the persisted run.
-- **Request UUID / idempotency identity:** client-provided UUID included in the request body, scoped to a tenant. Same UUID and same canonical body replays the existing run; same UUID and different body conflicts. A new scoring attempt uses a new UUID. Exact fingerprint normalization remains contract work.
+- **Request UUID / idempotency identity:** client-provided UUID included in the request body, scoped to `(app_id, account_id, request_id)`. Same UUID and same canonical body replays the existing run; same UUID and different body conflicts. A new scoring attempt uses a new UUID. Fingerprint normalization uses the HTTP-validated body serialized as sorted-key compact UTF-8 JSON; generated OpenAPI and fixtures define the input contract.
-- **Result GET:** tenant-authenticated read of the authoritative run result. Omni calls it after receiving a signed terminal notification.
+- **Result GET:** app-authenticated read of the authoritative run result. Omni calls it after receiving a signed terminal notification.
 - **HITL (human-in-the-loop):** human review workflow and customer actions owned by Omni. The provider does not authorize end users or own the review interface.
-- **Terminal notification:** provider-to-Omni signed HMAC webhook indicating a run outcome. It is a notification, not the result source of truth; Omni GETs the run. HMAC envelope, replay window, and retry protocol are unresolved.
+- **Terminal notification:** provider-to-Omni signed HMAC webhook carrying app/account/request/run identity and terminal status. Server-side `AI_PLATFORM_APP_WEBHOOKS` chooses each app's destination and secret. The notification is not the result source of truth; Omni GETs the run. Signature/replay and consumer writeback still require cross-service acceptance.
 - **Recovery:** after interruption of the single-process runtime, terminalize work that cannot continue because its volatile task/V-Key was lost. Recovery is not resumption and does not imply automatic re-execution.
-- **Retention:** proposed deletion/redaction of sensitive run material after 90 days. Backup deletion, audit retention, and tenant offboarding behavior need explicit approval.

-AI Platform publishes this provider contract; Omni implements its consumer. `openapi.json` is generated from backend routes. The JSON files under `fixtures/` are examples, not another validation schema. Cross-service acceptance still requires Omni to run them.
+Provider baseline: `omni-ai-platform-app-auth`, revision 2, 2026-09-30. `openapi.json` is generated from backend routes; `fixtures/` contains examples, not a second validation schema. The existing `v2` directory is retained without legacy compatibility. Cross-service acceptance remains pending until Omni verifies the same artifacts.
+
+## Authentication and identity
+
+POST/GET use `Authorization: Bearer <app_api_key>` for one Omni installation/environment. AI Platform resolves a stable `app_id`, requires active state and `lead_scoring` permission. Missing/invalid/inactive/revoked credentials return 401; missing permission returns 403 on both routes. Omni owns user/account/EMS authorization; AI Platform does not register accounts.
+
+POST `/v1/lead-scoring/runs` has exactly `request_id`, `account_id`, `subject_ref`, `snapshot`, `scoring_config`, `ai_profile`. Account ID is a nonblank string of 1–255 characters, preserved unchanged. Subject must match the snapshot EMS lead ID. `Idempotency-Key` represents the body request UUID. Self-supplied app/tenant/callback fields return 422.
+
+Each `scoring_config.rules[]` may include `description`: an optional string of at most 99 Unicode characters. Omitted or null descriptions preserve legacy normalized requests and replay fingerprints. Empty/whitespace descriptions are accepted but omitted from AI context. Nonblank descriptions are stored with the request, included in its fingerprint and sent as supplemental JSON context in the AI scoring pass, not as evidence or instructions. Rule matching, points and weights are unchanged; rule IDs, conditions, points and weights are not sent to AI. The request fixture includes a described rule and a legacy rule without this field.
+
+Deduplication is `(app_id, account_id, request_id)`: 202 and Location for new admission, 200 same canonical body/run, 409 changed body. Summary/detail carry app/account/request/run identity. GET another app's run returns 404. Key rotation preserves ownership/replay. Missing callback configuration blocks new admission with 503 after replay lookup; DB or scheduling unavailability also returns 503.
+
+Generate OpenAPI and serializer-derived summary/detail/signature examples with `make contract`; `uv run --no-sync python scripts/export_contract_fixtures.py --check` rejects fixture drift without modifying artifacts.

+## Credentials and configuration
+
+Operator CLI issues, rotates or revokes keys: `uv run --no-sync ai-platform create-app <app_id>`, `rotate-app-key <app_id>`, `revoke-app-key <app_id>`. Raw key is output only for issuance/rotation and must be transferred securely to Omni backend. Admin Web lists status and revokes access without receiving raw keys. Old tenant provisioning endpoints and provisioning-secret settings are removed.
+
+Omni backend configuration: `LEAD_SCORING_API_URL`, `AI_PLATFORM_APP_ID` (expected identity), `AI_PLATFORM_APP_API_KEY`. Provider configuration: `AI_PLATFORM_APP_WEBHOOKS`, JSON mapping app ID to `{"url":"https://omni.example.invalid/api/v1/internal/lead-scoring/notifications","signing_secret":"<server-secret-at-least-32-characters>"}`. Each app has its own URL/secret. Only development loopback HTTP is allowed; other environments require HTTPS. URL/secret/key never belong in browser-visible configuration. `X-Tenant-VKey` retains its existing name and RAM-only AIHub role.
 
 ## Terminal notification
 
-When `AI_PLATFORM_WEBHOOK_URL` and `AI_PLATFORM_WEBHOOK_SIGNING_SECRET` are both configured, AI Platform sends `POST` to that one server-side URL with `Content-Type: application/json`. The raw UTF-8 body contains exactly `event_id` (stable across retries), `run_id`, `tenant_id`, `status` (`completed` or `failed`), and `occurred_at` (UTC ISO 8601). It contains no run result, snapshot, tenant key, V-Key, or AI evidence. `occurred_at` is the terminal event time; it is not the send time.
+Webhook contains exactly `event_id`, `app_id`, `account_id`, `request_id`, `run_id`, `status` (`completed`/`failed`), `occurred_at` (UTC ISO 8601). It contains no scores, snapshot or evidence. Event ID/body remain stable across retry; `occurred_at` is terminal event time, not send time.
 
-`X-Webhook-Timestamp` is the UTC ISO 8601 time of **this delivery attempt**. `X-Webhook-Signature` is `sha256=` followed by the lowercase hex HMAC-SHA256 of the UTF-8 bytes `timestamp + "." + raw_request_body`, using the shared signing secret. Verify the signature over the raw body before parsing JSON, compare in constant time, and reject timestamps outside a five-minute window. The sample in `fixtures/webhook-delivery.json` uses the **test-only** secret `test-only-webhook-secret-32-characters-long` and fixes the exact bytes and signature.
+`X-Webhook-Timestamp` is UTC ISO 8601 for this delivery attempt. `X-Webhook-Signature` is `sha256=` plus lowercase hex HMAC-SHA256 over UTF-8 bytes `timestamp + "." + raw_request_body`.

-Omni must deduplicate by `event_id` and handle delivery retries without rescoring. Return any 2xx only after durably accepting the event; AI Platform retries non-2xx or network failures up to five total attempts, then marks the outbox event dead. The receiver uses its tenant key to `GET /v1/lead-scoring/runs/{run_id}`, checks tenant and terminal status, and applies its own latest-run-per-`(tenant, subject)` policy before writing to DotB EMS. The GET response is the result source of truth. Delivery may be repeated after a crash even if Omni previously replied 2xx.
+Omni commits the immutable source request before POST and durably accepts callback before ACK 202; an exact duplicate returns 200, conflicting identity/body returns 409. Dedupe `(app_id,event_id)`, bind run atomically even when callback precedes admission response, GET with app key and compare app/account/request/run/subject to the stored source before EMS writeback. Account authorization, enabled/EMS rechecks and latest-run ordering belong to Omni.
 
-Only enable the integration after Omni verifies this fixture, timestamp/replay handling, duplicate delivery and GET/writeback against its consumer. The webhook URL, signing secret and tenant key belong in server-side configuration; never put them in browser code.
+Provider retries network/non-2xx up to five attempts, then keeps a dead event. `uv run --no-sync ai-platform redeliver-notification <event_id>` retries the same event without rescoring. A crash may repeat a previously ACKed event. Webhook transport rejects redirects. GET is the result source of truth.
+
+## Migration and verification boundary
+
+The unreleased schema is consolidated in `0001_initial`, creating the current app-auth schema directly. Databases with the old local revisions need separate reconciliation or an explicitly approved rebuild; the baseline does not automatically stamp, reset or map legacy data. Provider tests do not prove Omni request persistence, callback receiver or EMS writeback. Run the shared validation checklist on both applications with mock AI/EMS before enabling real integration.

+title: App auth provider handoff
+description: Bằng chứng kiểm thử AI Platform theo app-auth revision 2 và các bước còn cần nghiệm thu với Omni.
+status: draft
+---
+
+# Bàn giao app auth phía AI Platform
+
+Phần provider đã triển khai theo baseline `omni-ai-platform-app-auth`, revision 2, ngày 2026-09-30. Spec trong repo là `docs/specs/ai-platform-lead-scoring.md`; OpenAPI và fixtures tại `contracts/lead-scoring/v2/` là artifact provider-generated. Trạng thái `review_ready` của spec dành cho nghiệm thu liên dịch vụ, không phủ nhận quyền triển khai đã được phê duyệt.
+
+## Phạm vi hoàn tất
+
+- POST/GET dùng Bearer app key, suy ra app ID ổn định; kiểm tra active và quyền `lead_scoring`. Thiếu/sai/revoked/inactive trả 401, thiếu quyền trả 403; GET run của app khác trả 404.
+- Request có account ID không rỗng, UUID chuẩn và subject khớp snapshot lead. Run/replay unique theo `(app_id, account_id, request_id)`; 202 mới, 200 replay, 409 body khác. PostgreSQL test kiểm tra POST đồng thời chỉ schedule một run.
+- Summary/detail/outbox/webhook dùng app/account/request/run identity. Rotate key giữ ownership/replay và permission. Tenant auth/provisioning runtime, endpoints, UI và env cũ đã thay trực tiếp. Theo quyết định gộp schema chưa phát hành của người dùng, source hiện chỉ còn baseline `0001_initial`.
+- Mapping backend `AI_PLATFORM_APP_WEBHOOKS` định tuyến URL/secret theo app. Thiếu mapping chặn run mới với 503 sau replay lookup. Event/body ổn định qua retry, timestamp gửi mới mỗi attempt, chữ ký HMAC trên raw bytes, không follow redirect. Hết năm attempts giữ dead event; CLI redeliver cùng event, không rescore.
+- CLI cấp/rotate/revoke key; DB chỉ lưu verifier. Admin session/CSRF độc lập; Web chỉ list/revoke, không nhận raw app key. Fixture runner dùng app key server-only; demo seed yêu cầu key đã cấp, không tự provisioning.
+- Generated OpenAPI khai báo Bearer auth và lỗi HTTP. Generator xuất summary/detail/webhook từ serializers; điểm và breakdown của examples được tính bằng scoring hiện tại từ request fixture. Chế độ `--check` phát hiện fixture drift mà không ghi file.
+- Scoring pipeline, giới hạn snapshot, rules-only/hybrid/fallback/failed và RAM-only `X-Tenant-VKey` được giữ trong regression suite. Lỗi validation/DB trên scoring API trả thông báo an toàn, không echo credential hoặc SQL.
+
+## Bằng chứng provider local
+
+Chạy tại root AI Platform, dùng môi trường project-local Python 3.13.14 và PostgreSQL test database `ai_platform_test` cho database tests:
+
+- `uv run --no-sync ruff check src tests scripts migrations`: PASS.
+- `uv run --no-sync ruff format --check src tests scripts migrations`: PASS, 78 files đã đúng format.
+- `uv run --no-sync pyright`: PASS, 0 errors / 0 warnings.
+- `uv run --no-sync lint-imports`: PASS, 3 contracts kept / 0 broken.
+- `make contract`: PASS; sinh OpenAPI và serializer-derived fixtures.
+- `uv run --no-sync python scripts/export_contract_fixtures.py --check`: PASS.
+- `set -a; . ./.env.test; set +a; uv run --no-sync python /tmp/verify_ai_platform_baseline.py`: PASS, 193 passed; 1 cảnh báo deprecation Starlette/httpx đã có. Harness tạm tạo schema mới, chạy Alembic upgrade/check rồi pytest, sau cùng chỉ xóa schema nó tạo và xác nhận public revision không đổi. `make test` trực tiếp trên public schema cũ chưa chạy lại vì public vẫn mang revision đã gộp bỏ; cần xử lý DB local riêng trước.
+- `make check-fast`: PASS, Ruff/format/YAML/TOML/conflict/private-key hooks. Lệnh này chỉ xử lý tracked files; untracked source được kiểm tra bằng các lệnh Ruff/Pyright/pytest và review trực tiếp.
+- `docker compose config --quiet`: PASS.
+- `uv run --no-sync alembic heads`: PASS, `0001_initial` là head duy nhất.
+- `make build`: PASS ở phiên app-auth trước khi gộp migration, tạo `ai-platform-backend:local` và `ai-platform-web:local`. Chưa rebuild Docker images sau gộp; không deploy hoặc chứng minh runtime toàn Compose stack.
+- `git diff --check`: PASS.
+
+Chạy tại `apps/web`:
+
+- `bun run format:check`: PASS.
+- `bun run check`: PASS, 0 errors / 0 warnings; sinh lại types từ OpenAPI.
+- `bun run test`: PASS, 6 files / 16 tests.
+- `bun run build`: PASS. Có thông báo empty chunk và plugin timing; exit 0. Docker Web build cũng pass với artifact/fixture được copy vào build context.
+
+Các tests auth/replay/outbox sử dụng PostgreSQL thật và HTTP AI/webhook giả lập. Chúng không gọi hai backend AI Platform và Omni qua mạng thực tế, không xác minh EMS writeback hoặc AIHub sandbox.
+
+## Migration baseline và database local
+
+Người dùng đã cho phép gộp source migration vì AI Platform chưa phát hành. Source hiện chỉ có `migrations/versions/0001_initial.py`, tạo đủ tám bảng của schema hiện tại. Đã bỏ chuỗi tenant→app cùng guard tests; `tests/test_initial_migration.py` kiểm tra khởi tạo, schema/model drift gồm server defaults và indexes, FK/unique theo app-account-request, unique notification/run và cascade xóa outbox, rồi downgrade/upgrade trong schema tạm.
+
+Đồng bộ metadata ORM với các defaults/index đã có trong DDL: AI profile active=false, run degraded=false và index dispatch outbox. Không đổi ownership, API hoặc hành vi scoring.
+
+Database test hiện hữu vẫn ở `0009_app_auth`; việc dọn đúng 97 legacy audit rows đã được phép diễn ra ở phiên trước và không được lặp lại. Phiên gộp source này không reset/stamp hoặc thay dữ liệu public. Full suite chạy trên schema mới tạm trong `ai_platform_test`; Alembic upgrade/check và 193 tests đều pass, schema tạm đã dọn, public revision giữ nguyên.
+
+Database local có revision cũ cần xử lý riêng trước khi chạy lại backend/migrate/tests trực tiếp. Có thể dùng database mới; việc dựng lại/xóa hoặc stamp database hiện hữu cần kiểm tra schema và xác nhận phạm vi dữ liệu cần giữ/bỏ. Startup vẫn từ chối revision không khớp, không tự migrate. Các migration phát hành sau baseline này được giữ lịch sử như bình thường.
+
+## Review và giới hạn nghiệm thu
+
+Review áp dụng `docs/project_quality.md` cho tracked/untracked changes, gồm HTTP/application/persistence/bootstrap, schema/migrations, env/Compose/CI, serializers/fixtures và Admin Web. Các module lớn hiện hữu như wiring, persistence models và HTTP schemas vẫn giữ boundary hiện tại; không mở rộng thành refactor ngoài phạm vi app auth.
+
+Phần Omni có hồ sơ kiểm thử riêng trong tài liệu phối hợp. Phiên provider không sửa repo Omni và không chạy lại hoặc xác nhận các kết quả consumer đó. Những việc sau còn pending:
+
+1. Omni import đúng artifact provider revision 2 và đối chiếu request/summary/detail/webhook; không coi contract provisional riêng là artifact đã thống nhất.
+2. Chạy hai backend local cùng credential test và AI/EMS giả lập: admission, terminal callback, GET, đối chiếu request nguồn và ghi đúng lead. Kiểm tra early callback, timeout/replay, duplicate/conflict, account authorization và ordering trong flow thực tế.

 # Lead Scoring v2
 
-Đặc tả này thay thế hành vi Pilot trong `old_repo/`. API còn phải được DotB-Omni kiểm tra bằng vài fixture chung trước khi coi là hợp đồng tích hợp đã phát hành. Các quyết định dưới đây đã được chốt trong kế hoạch rebuild; các giới hạn hạ tầng/AIHub chưa xác minh được ghi riêng ở cuối.
+Thiết kế app auth được người dùng cho phép triển khai theo baseline chung `omni-ai-platform-app-auth`, revision 2, ngày 2026-09-30. Đặc tả này ghi lại phần provider trong repo; generated OpenAPI và các fixture tại `contracts/lead-scoring/v2/` xác định wire shape. Tên thư mục `v2` chỉ là vị trí artifact hiện có, không tạo yêu cầu tương thích tenant auth cũ. Nghiệm thu liên dịch vụ với Omni/AIHub vẫn cần bằng chứng riêng.
 
 ## Sở hữu
 
-- DotB-Omni tạo snapshot, định nghĩa rules/points và rule/AI weights, score bands, HITL/review/override, quyền người dùng và hành động CRM. Omni gửi tenant key và V-Key từ backend của mình, không từ browser.
+- DotB-Omni quản lý users/accounts, quyền EMS, connection, enabled/config, snapshot, rules/points, weights, score bands, HITL/review/override và CRM writeback. Omni gửi app key và V-Key từ backend, không từ browser.
-- AI Platform xác thực tenant, thực thi rules của Omni, gọi nhà cung cấp AI đã chọn khi cần, tính rule_score/ai_score/final_score, lưu run và gửi thông báo kết thúc. Lead Scoring mặc định dùng AIHub; quản trị nội bộ có thể kích hoạt một AI profile có phiên bản chọn AIHub hoặc OpenAI-compatible cho toàn service. Omni không chọn provider trong từng request. Admin Web nội bộ chỉ quản lý AI profile và xem/chạy fixtures; không quản lý customer rules/review.
+- AI Platform xác thực installation bằng app key, kiểm tra active và quyền `lead_scoring`, thực thi scoring, lưu run và thông báo kết thúc. Không đăng ký account hoặc xác thực user/credential EMS.
-- DotB EMS là nguồn sự thật CRM. Omni nhận webhook terminal rồi GET chi tiết run trước khi ghi EMS. Webhook không chứa snapshot, V-Key hay AI evidence.
+- AI profile nội bộ có phiên bản chọn AIHub hoặc OpenAI-compatible cho service; Omni không chọn provider từng request. Admin Web chỉ quản lý AI profile, xem/chạy fixtures và xem/thu hồi app access; không quản lý nghiệp vụ khách hàng hoặc hiển thị raw app key.
+- DotB EMS là nguồn sự thật CRM. Webhook chỉ thông báo; Omni GET chi tiết, đối chiếu identity/lead/request nguồn trước khi ghi EMS.
 
 ## Admission và idempotency
 
-`POST /v1/lead-scoring/runs` nhận `Authorization: Bearer <tenant_key>`, `Idempotency-Key: <UUID>` và `X-Tenant-VKey` tùy chọn. Body chứa `request_id` cùng UUID, `subject_ref`, snapshot, app-defined scoring configuration (`version`, rules/points, `rule_weight`, `ai_weight`) và AI profile. Tenant được suy ra từ key xác thực, không từ body. `GET /v1/lead-scoring/runs/{run_id}` chỉ trả dữ liệu của tenant đó.
+`POST /v1/lead-scoring/runs` nhận `Authorization: Bearer <app_api_key>`, `Idempotency-Key: <UUID>` và `X-Tenant-VKey` tùy chọn. App ID được suy ra từ key, không từ body. Body có đúng `request_id`, `account_id`, `subject_ref`, `snapshot`, `scoring_config`, `ai_profile`.
 
-- Fingerprint SHA-256 của canonical **body Omni**; không bao gồm tenant key, V-Key hoặc AI profile do server chọn. Lookup `(tenant, request_id)` trước khi chọn profile. Cùng key/body trả run cũ mà không schedule AI; cùng key/body khác trả 409. PostgreSQL unique constraint giải quyết concurrent requests; retry admission đã commit nhưng mất response dùng cùng UUID/body.
+- `request_id` là UUID chuẩn lowercase có dấu gạch ngang; header phải biểu diễn cùng UUID. `account_id` là chuỗi 1–255 ký tự không chỉ whitespace, giữ nguyên case/whitespace, Omni dùng `account.id.to_s`. Provider không kiểm tra account tồn tại ở Omni. `subject_ref` phải khớp `snapshot.lead_profile.ems_lead_id`. Field dư gồm app/tenant/callback bị từ chối 422.
-- Run mới đóng băng AI profile đang active (gồm provider và model), INSERT + COMMIT trước khi schedule và trả 202; `Location` trỏ đến GET. Nếu không schedule được, run thành failed và response phản ánh trạng thái thực, không để pending giả. Chấm lại hoặc thử profile mới dùng UUID mới. Không reuse UUID quá 90 ngày: run và fingerprint bị xóa, không có tombstone.
+- Thiếu/sai/revoked key hoặc inactive app trả 401; app hợp lệ thiếu quyền Lead Scoring trả 403, cả POST và GET. GET run thuộc app khác hoặc không tồn tại trả 404. Omni sở hữu account/user isolation trong app của mình.
-- Validate chặt loại rule/operator/value, tổng weights bằng 1, score/points và dữ liệu snapshot; đầu vào sai trả 422. Snapshot tối đa 10 conversations, 50 messages, 20.000 ký tự nội dung và 90 ngày evidence; giữ thứ tự deterministic. Kích thước toàn body có hard cap. Không hard-code rule giáo dục hay category/action/review state.
+- Fingerprint SHA-256 của canonical body sau HTTP validation, không chứa secret headers. Lookup `(app_id, account_id, request_id)` trước khi chọn AI profile hoặc kiểm tra webhook availability. Cùng identity/body trả 200 cùng run hiện tại, không schedule lại; body khác trả 409. PostgreSQL unique constraint và transaction giải quyết POST đồng thời. Account/app khác được dùng cùng request UUID.
+- Run mới đóng băng profile đang active, INSERT + COMMIT trước schedule, trả 202 và `Location`. Thiếu mapping callback trả 503 trước INSERT; replay vẫn hoạt động khi mapping bị gỡ. DB unavailable hoặc scheduling failure trả 503; scheduling failure terminalize run thay vì để pending giả. Omni retry cùng UUID/body vì timeout/503 có thể xảy ra sau commit.
+- Summary/detail có app/account/request/run identity, không tenant ID. Chấm lại hoặc dùng profile mới cần UUID mới. Không reuse UUID quá retention 90 ngày: run và fingerprint bị xóa, không có tombstone.
+- Giữ rule/operator/value validation, tổng weights bằng 1, score/points và snapshot limits: 10 conversations, 50 messages, 20.000 ký tự nội dung, 90 ngày evidence, snapshot 100KB và hard cap toàn body. Không hard-code category/action/review state.
+- Mỗi `scoring_config.rules[]` có `description` tùy chọn, chuỗi tối đa 99 ký tự Unicode. Thiếu hoặc `null` giữ wire body chuẩn hóa cũ để bảo toàn fingerprint/replay; chuỗi rỗng hoặc chỉ whitespace được nhận nhưng không thêm vào AI context. Mô tả có nội dung được lưu cùng request và tham gia fingerprint, nên đổi mô tả với cùng identity trả 409. Mô tả không thay đổi điều kiện khớp, points hoặc breakdown của bộ chấm quy tắc.
 
 ## Kết quả và lỗi
 
 - `ai_weight=0`: `rules_only`, `degraded=false`, `ai_score=null`, không gọi AIHub và không cần V-Key.
-- `ai_weight>0` nhưng thiếu V-Key khi profile chọn AIHub, hoặc nhà cung cấp đã chọn lỗi: `rules_only_fallback`, `degraded=true`, `ai_score/ai_confidence=null`, `final_score=rule_score`, `error_code` đã chuẩn hóa. Không tự AI retry.
+- `ai_weight>0` thiếu V-Key với AIHub hoặc provider lỗi: `rules_only_fallback`, `degraded=true`, `ai_score/ai_confidence=null`, `final_score=rule_score`, mã lỗi chuẩn hóa. Không tự AI retry.
-- AI thành công: `hybrid`, `degraded=false`, `final_score=clamp(round(rule_score*rule_weight + ai_score*ai_weight), 0, 100)`; trả breakdown, reasoning/evidence/confidence được giới hạn. Cùng raw signals có thể ảnh hưởng cả rules lẫn AI; không gửi app rules/points vào AI prompt để hạn chế chấm hai lần.
+- AI thành công: `hybrid`, `degraded=false`, `final_score=clamp(round(rule_score*rule_weight + ai_score*ai_weight), 0, 100)`; breakdown/reasoning/evidence/confidence có giới hạn. Chỉ gửi các `description` có nội dung làm ngữ cảnh bổ sung ở bước chấm AI cho cả AIHub và OpenAI-compatible; không gửi rule IDs, điều kiện, points hoặc weights. Mô tả được đóng gói như dữ liệu JSON, không phải chỉ dẫn hệ thống hay bằng chứng về khách hàng; snapshot và evidence vẫn là căn cứ chấm điểm.
-- Bug/code/DB failure thành `failed`, không giả là AI fallback. AI profile gồm provider, versioned model, prompts và timeout/token limits, không sở hữu app rules hoặc weights. Profile cũ mặc định AIHub; đổi provider cần phiên bản mới, ghi audit actor/version/provider cùng transaction, không ghi secret. Medium two-pass là mặc định; Light/Heavy chỉ bổ sung khi có nhu cầu và được xác minh với nhà cung cấp.
+- Bug/code/DB failure thành `failed`, không giả là AI fallback. Đổi profile/provider cần version mới và audit trong cùng transaction. Medium two-pass là mặc định khi dùng AI; Light/Heavy cần nhu cầu và xác minh riêng.
 
-## Key, session và delivery
+## Credential và runtime
 
-- Platform có một active tenant key/tenant dùng chung cho LS và feature sau này: provisioner secret server-side cấp qua `POST /v1/platform/tenant-keys`, raw trả một lần, DB chỉ có verifier/digest; cấp trùng 409. Nếu response mất sau commit, admin CLI rotate cũ/thay mới atomically; không tự rotate khi POST bị replay.
+- Một app ID ổn định và một key cho mỗi Omni installation/environment, dùng chung các account. DB chỉ lưu SHA-256 verifier, active và quyền Lead Scoring. Rotate giữ app ID, GET/replay run cũ và permission; key cũ hết hiệu lực. Không tenant provisioning endpoint/secret, account registration hoặc dual auth.
-- `X-Tenant-VKey` chỉ giữ trong RAM của current scoring task và forward `Authorization: Bearer` tới AIHub khi profile chọn AIHub. OpenAI-compatible dùng URL được lưu theo phiên bản profile; API key tùy chọn vẫn cấu hình ở server và chỉ được gửi tới URL đã cấu hình cho key đó, không tự gửi sang URL mới nhập ở Web. HTTP chỉ cho loopback khi development, ngoài development yêu cầu HTTPS. Chưa xác nhận quản lý key cho các URL production khác nhau. Không persist/log/trace/error/browser bất kỳ raw secret nào. V-Key không phải platform authentication. Admin session độc lập, password hash, CSRF cho mutation, cookie bảo vệ, logout/expiry và audit thay đổi config/key không kèm secrets.
+- Vận hành dùng CLI `create-app`, `rotate-app-key`, `revoke-app-key`; raw key chỉ trả ở thao tác CLI cấp/rotate. Admin session độc lập, password hash, CSRF mutation, cookie bảo vệ, logout/expiry và audit không chứa secret. Web chỉ list/revoke app access.
-- Một backend process + asyncio tasks. Startup trước readiness terminalize pending/running cũ thành `failed/worker_interrupted`; task exception cũng terminalize. V-Key không durable nên không resume AI sau crash; caller muốn làm lại dùng UUID mới.
+- `X-Tenant-VKey` giữ tên hiện tại vì là giao tiếp provider AI riêng; chỉ giữ trong RAM current task, forward Bearer tới AIHub. OpenAI-compatible dùng URL versioned trong profile, server API key chỉ gửi tới URL được cấu hình cho key đó. HTTP chỉ cho loopback development, production yêu cầu HTTPS. Không persist/log/trace/error/browser raw secret.
-- Terminal transition và PostgreSQL outbox event commit cùng transaction. Dispatcher gửi HMAC-signed webhook tới một Omni URL cố định với event ID/timestamp, bounded retry và dead-letter. Omni xác minh chữ ký/chống replay/dedupe, GET chi tiết và áp dụng writeback theo run mới nhất của `(tenant, subject)`; delivery replay không chấm AI lại. Không broker, dynamic subscription, polling scheduler tại Omni.
+- Một backend process với asyncio tasks. Startup đọc migration head, không tự migrate; terminalize pending/running bị mất thành `failed/worker_interrupted`. Không resume V-Key hoặc tự chấm lại sau crash.
+- Schema chưa phát hành được gộp thành một migration `0001_initial`, tạo thẳng app auth hiện tại; không giữ chuỗi chuyển đổi tenant cũ. Database local mang revision cũ cần xử lý riêng trước khi chạy lại, không tự stamp/reset hoặc xóa dữ liệu. Sau lần phát hành đầu tiên, giữ lịch sử migration đã phát hành.
+
+## Terminal delivery
+
+- Terminal transition và outbox commit cùng transaction. `AI_PLATFORM_APP_WEBHOOKS` là JSON mapping `app_id → {"url":"...","signing_secret":"..."}`; secret tối thiểu 32 ký tự, HTTPS hoặc development loopback HTTP, không credentials/query/fragment trong URL. Không request callback hoặc subscription framework.
+- Webhook tới endpoint Omni `/api/v1/internal/lead-scoring/notifications`, body đúng `event_id`, `app_id`, `account_id`, `request_id`, `run_id`, `status`, `occurred_at`. Identity lấy từ run đã lưu; không điểm/snapshot/evidence/secret. Event/body bất biến qua retry; timestamp header mới cho từng attempt.
+- HMAC-SHA256 trên byte UTF-8 `timestamp + "." + raw_body`, header `X-Webhook-Signature: sha256=<lowercase hex>`, `X-Webhook-Timestamp` ISO UTC. Omni xác minh raw bytes, constant-time, ±5 phút, giới hạn body 8192 bytes rồi parse/schema.
+- Omni lưu event trước ACK 202, duplicate đúng body trả 200, dedupe `(app_id,event_id)`, identity/conflicting duplicate trả 409. App/request nguồn không khớp trả 404. Omni GET bằng app key và đối chiếu app/account/request/run/lead trước writeback. Callback sớm tra được request nguồn đã commit trước POST.
+- Provider retry non-2xx/network tối đa 5 attempts rồi dead. `redeliver-notification <event_id>` đặt lại delivery của cùng event, không tạo run hoặc rescore. Không follow redirect khi gửi webhook.
 
 ## Privacy và nghiệm thu
 
-- Scheduled retention xóa run, snapshot, fingerprint, evidence và outbox liên quan sau 90 ngày; test xóa thật. Không lưu thông tin nhạy cảm trong payload webhook/log. Chính sách xóa tenant/offboarding và vòng đời backup phải chốt trước production; xóa DB không có nghĩa xóa ngay backup.
+- Retention xóa run/snapshot/fingerprint/evidence và outbox liên quan sau 90 ngày. App/account offboarding và backup lifecycle phải chốt trước production; DB deletion không chứng minh backup đã xóa.
-- Fixture chung tối thiểu: admission/replay và 409, rules-only/hybrid/fallback, failed run, webhook HMAC và Omni GET/writeback. Generated OpenAPI là nguồn schema; không lặp lại bộ schema cho từng projection không có consumer.
+- Omni lưu request nguồn bất biến trước HTTP, retry cùng UUID/body, bind run atomically, giữ account/subject ordering namespace `lead-scoring`, recheck enabled/EMS trước writeback. Đây là trách nhiệm consumer cần nghiệm thu ở Omni, không được suy ra từ tests provider.
-- Cần xác minh bằng sandbox AIHub về endpoint, strict structured output, model, timeout, quota và lỗi; Omni phải xác nhận fixture, signature/replay và writeback. Hosting, TLS, secret injection, backup/restore và alert destination chốt theo nơi deploy. Chưa khẳng định production-ready khi các điều đó chưa được kiểm chứng.
+- Nghiệm thu: app auth/permission, cross-app GET, account/app replay isolation, concurrent POST, rotation, callback availability, HMAC và redelivery, rules-only/hybrid/fallback/failed regression, migration khởi tạo/schema/constraints/lifecycle, secret safety và Web checks. Một test liên ứng dụng với AI/EMS giả lập vẫn bắt buộc trước kết luận integration chạy đúng.
+- AIHub sandbox protocol/model/timeout/quota và production hosting/TLS/secret injection/backup/alerts chưa được xác minh. Không tuyên bố production-ready từ local checks.

 - AIHub: V-Key supplied per request in RAM, Bearer forwarding, medium bounded two-pass when AI is required. Lead Scoring's versioned AI profile defaults to AIHub and may select a separate OpenAI-compatible adapter; its URL is stored with the version and its model comes from the profile. The optional server-side API key is sent only to the URL configured for that key; changing the URL in Admin Web does not forward that key. Only development permits loopback HTTP; production URLs require HTTPS. Actual provider protocol/model/timeout and quotas require sandbox verification; no server-wide tenant V-Key.
