 | `ILicenseVerificationService` | backend-phase-15 | eNamad / MoH establishment-permit — manual approve | _tbd_ | Real registry/API | 🔴 |
 | `IPaymentCaptureSimulator` | backend-phase-9 | The **temporary conversion trigger** standing in for b10's real card capture. `MockPaymentCaptureSimulator` (`Baya.Infrastructure.CrossCutting/Seams/`) returns a deterministic *succeeded* capture (a fake `gateway_reference` + a configurable `psp_fee_amount`) so `ConvertRequestToBookingCommand` is exercisable now; a config switch forces a *failed* capture (→ no booking is created). **This is the trigger, not a parallel money path** — registered singleton in `AddCrossCuttingSeams` | `Seams:PaymentCapture:ForceFailure` (default `false`), `Seams:PaymentCapture:PspFeeAmount` (default unset) | In b10: 1) build the real card capture (`payment_transactions`, PSP/IPG client, webhook verify); 2) on a real `payment_transactions.succeeded`, call `ConvertRequestToBooking` **directly** (the same conversion command that computes the three-amount split + generates sessions) instead of this seam; 3) remove the `IPaymentCaptureSimulator` registration + `MockPaymentCaptureSimulator`; the conversion/idempotency logic is unchanged | 🟡 |
 | `INurseSearch` | backend-phase-7 | The search-service seam (read side). **The MVP impl `SqlNurseSearch` (`Persistence/Services/Search/`) is REAL, not a mock** — it reads the maintained `nurse_search_index WHERE is_searchable=1`, applies the category/city/district (NULL=whole-city)/gender/price filters + rating sort + pagination, projected & `AsNoTracking`. Registered by `AddPersistenceServices`, config-selected. Only the DEFERRED Elasticsearch backend is unbuilt | `Search:Backend` (default `sql`; any other value throws until Elastic ships) | 1) add an Elasticsearch client package (`Elastic.Clients.Elasticsearch`) to `Directory.Packages.props`; 2) define the index mapping (the `NurseSearchResultDto` fields + `is_searchable`); 3) implement `ElasticNurseSearch : INurseSearch` (same filters/sort/paging) reading the ES index; 4) build the feeder that consumes the `ISearchIndexMaintainer` change events via an **outbox/CDC** stream into ES (see the next row); 5) point `Search:Backend=elastic` in config — **callers unchanged**; 6) keep the SQL index as the projection/fallback + the reconciliation source (`RebuildAsync`); 7) test filter/sort/paging parity vs `SqlNurseSearch` | 🟢 SQL real; Elastic 🟡 |
+| `IPaymentProvider` | backend-phase-10 | Card PSP acquirer — `MockPaymentProvider` (`Baya.Infrastructure.CrossCutting/Seams/`), **no external call**: `InitPaymentAsync` → a deterministic `gatewayReferenceCode` (`mock-ref-{requestId}-{key}`) + a fake redirect URL; `VerifyAsync` → instant `Succeeded` echoing the expected amount (the server-side re-check); `RefundAsync` → always `Succeeded` (for b11 to call). Registered singleton in `AddCrossCuttingSeams` | none today; real client needs merchant id + terminal/IBAN registration + sandbox flag from `payment_gateways.config_json` (encrypted), not appsettings | 1) pick ZarinPal/Sadad/Vandar/Jibit as an acquirer-with-تسهیم, add its client package to `Directory.Packages.props`; 2) implement `InitPaymentAsync` (open the IPG session, return the Shaparak-routed redirect + reference), `VerifyAsync` (the mandatory server-side `verify` re-check of amount + reference — **never trust the callback alone**), `RefundAsync`; 3) read merchant id/terminal from the encrypted `payment_gateways.config_json`; 4) a config-driven `IProviderRegistry`/factory selects the concrete provider per gateway so a cut-off provider swaps without code change; 5) persist the full gateway response into `gateway_response_json`; 6) swap the registration (config-selected) — handlers unchanged | 🟡 |
+| `ISettlementSplitProvider` | backend-phase-10 | تسهیم settlement-sharing — `MockSettlementSplitProvider` (`.../Seams/`) records the split intent and returns `Settled` for any legs whose sum is positive; the platform never moves money. Registered singleton in `AddCrossCuttingSeams` | none today; real client needs each beneficiary's registered SHEBA + split-by-ratio config | 1) pick the acquirer's تسهیم API, implement `RegisterSplitAsync(bookingId, legs)` to register the split-by-ratio to each beneficiary's **registered IBAN** (nurse payout + platform commission), honouring the ~100,000 IRR min-amount caveat; 2) resolve each nurse's SHEBA from `nurse_bank_accounts` (the b3 `matched_national_id` gate) and the platform SHEBA from config; 3) `GetSplitStatusAsync` polls the provider; the provider credits IBANs directly — the ledger only mirrors it; 4) swap the registration (config-selected) | 🟡 |
+| `IWebhookVerifier` | backend-phase-10 | PSP callback signature verify — `MockWebhookVerifier` (`.../Seams/`) treats the signature as valid unless the body carries `Seams:Payments:InvalidSignatureMarker`, and extracts `external_event_id`/`event_type`/`gateway_reference_code` from a small JSON body (so tests can replay duplicates + exercise the invalid-signature path). Registered singleton in `AddCrossCuttingSeams` | `Seams:Payments:InvalidSignatureMarker` (default `INVALID_SIGNATURE`) | 1) implement the per-provider HMAC/signature scheme (verify the raw body against the provider's signing key from the gateway config); 2) where a provider offers no signature, fall back to the mandatory server-side `verify` re-check (amount + reference) via `IPaymentProvider.VerifyAsync`; 3) parse the real provider event shape into `WebhookVerification`; 4) swap the registration (config-selected) — the `HandlePaymentWebhook` upsert-first/no-op-on-duplicate ordering is unchanged | 🟡 |
+| `IDistributedLock` | backend-phase-10 | Money-path mutex — `InProcessDistributedLock` (`.../Seams/`): a per-key `SemaphoreSlim` so the capture path runs the same acquire/release shape it will with real Redis, **within one process only**. **Not** a cross-instance correctness guarantee — the DB uniques/state-machine are the authoritative backstop. Registered singleton in `AddCrossCuttingSeams` | none today; real client needs a Redis connection string | 1) add `StackExchange.Redis` to `Directory.Packages.props`; 2) implement `AcquireAsync(key)` with a lease/expiry (RedLock-style SET NX PX + a token-checked release), key convention `booking:{id}:payment`; 3) bind `Seams:Payments:Redis` (or reuse the `ICacheService` Redis swap); 4) swap the registration (config-selected) — handlers unchanged, and correctness still rests on the DB uniques if Redis is down/expired | 🟡 |
 | `ISearchIndexMaintainer` (the "`ISearchIndexWriter`" event shape) | backend-phase-7 | The index-maintenance seam (write side). **The inline SQL path is REAL** — `SearchIndexMaintainer` (`Persistence/Services/Search/`) re-derives `nurse_search_index` from source and **stages** it inside the owning source write's unit of work (single `CommitAsync`), invoked from the b3/b4/b5/b6 handlers (`ReindexVariantAsync`/`ReindexNurseAsync`/`FanOutServiceAreaAsync`/`RemoveServiceAreaRowsAsync`/`RebuildAsync`). Only the **outbox/queue routing** for an async Elastic feeder is deferred — the seam is shaped so the same change events can later be emitted to an outbox instead of an inline upsert | _none_ | 1) introduce an `outbox` table + a SaveChanges interceptor that captures each maintainer change as an event row in the same transaction; 2) a background feeder (Hangfire/Quartz or a hosted service) reads the outbox and applies to `ElasticNurseSearch`; 3) keep the inline SQL upsert as the projection/fallback so `RebuildAsync` stays the reconciliation path; 4) test that an outbox replay converges to the same rows as the inline path | 🟡 outbox deferred (inline real) |
