## 2. Discrepancies Found
### 2.1 Missing modules (documented but not implemented)
| Module | Doc claims | Reality in code |
|---|---|---|
| **Dispute** | `backend/src/services/dispute/`, `backend/src/models/Dispute.ts`, `/api/disputes` | **None exist**. No directory, no model, no routes, no controller. |
| **Blog** | `services/blog/blogRoutes.ts` | **Does not exist**. |
| **Points** | `services/points/pointsRoutes.ts`, `Points API` | **Does not exist**. |
| **Admin** | `services/admin/adminRoutes.ts`, `Admin API` | **Does not exist**. |
| **Review** | `Review.md` data model | `backend/src/models/Review.ts` **does not exist**. |
| **PointTransaction** | `PointTransaction.md` data model | `backend/src/models/PointTransaction.ts` **does not exist**. |
| **LevelConfig** | `LevelConfig.md` data model | `backend/src/models/LevelConfig.ts` **does not exist**. |
| **ShopSettings** | `ShopSettings.md` data model | `backend/src/models/ShopSettings.ts` **does not exist**. |
| **BlogPost** | `BlogPost.md` data model | `backend/src/models/BlogPost.ts` **does not exist**. |
### 2.2 Data-model enum mismatches
| Model | Field | Doc value | Code value | Severity |
|---|---|---|---|---|
| **Payment** | `provider` | `shkeeper` / `other` | `shkeeper` / `request.network` / `request-network` / `other` | Medium |
| **Payment** | `escrowState` | 6 values | 8 values (`+ cancelled`, `+ partial`) | Medium |
| **Payment** | `metadata` | SHKeeper fields only | Also has `requestNetworkRequestId`, `requestNetworkPaymentReference`, `requestNetworkSecurePaymentUrl`, `requestNetworkData` | Low |
| **Payment API** | Status list | Missing `confirmed` and `processing` in the "Status model" prose | Code has full 7-value enum incl. `confirmed`, `processing` | Medium |
### 2.3 User-model fields documented but missing from schema
The `User.md` table describes `referralCode`, `referredBy`, `points.{total,available,used,level}`, and `referralStats.{totalReferrals,activeReferrals,totalEarned}`. These fields **do not exist** in `backend/src/models/User.ts` (line count stops at 201; no referral or points subdocuments). The associated unique/sparse indexes are also absent.
### 2.4 Authentication requirements (post-remediation drift)
Several endpoints in `Payment API.md` were documented as **unauthenticated** but the code now enforces `authenticateToken` (and in some cases `authorizeRoles`):
| Endpoint | Doc auth | Code auth | Fix applied |
|---|---|---|---|
| `POST /api/payment/decentralized/save` | No | Bearer JWT + ownership | ✅ Updated doc |
| `PUT /api/payment/decentralized/update` | No | Bearer JWT + ownership | ✅ Updated doc |
| `GET /api/payment/decentralized/history/:userId` | No | Bearer JWT + `requireOwnershipOrAdmin` | ✅ Updated doc |
| `POST /api/payment/decentralized/verify/:paymentId` | No | Bearer JWT + ownership | ✅ Updated doc |
| `POST /api/payment/decentralized/verify-all-pending` | No (cron) | Bearer JWT + `admin` | ✅ Updated doc |
Additionally, the legacy `routes.ts` marketplace router applies `authenticateToken` globally, but `app.ts` mounts the **controller router** (`controllerRoutes.ts`) which exposes public read endpoints. The docs correctly describe the controller-router behaviour.
### 2.5 Rate limiting
All architecture and API docs stated rate limiting was **disabled** (`app.ts:227`). After remediation it is **enabled** with four tiers:
- Global: 100 req / 15 min
- Auth: 10 req / 15 min
- Payment: 30 req / 15 min
- AI: 20 req / 15 min
### 2.6 Socket.IO authentication
Docs described Socket.IO as an open real-time channel. In reality `app.ts` now enforces:
- JWT verification on every connection (`io.use(jwt.verify(...))`).
- Strict room-membership checks (`join-user-room`, `join-request-room`, `join-chat-room`, etc.) that reject cross-user or unauthorized joins.
### 2.7 Passkey hardening
`passkeyService.ts` now implements:
- Single-use challenge consumption (`consumeChallenge` deletes immediately after read).
- 5-minute challenge TTL with periodic cleanup.
- Explicit expiry error messages.
- This was not documented in the Security Architecture or Authentication API docs.
### 2.8 Endpoint path errors in flow docs
- `Payment Flow - DePay & Web3.md` referenced `POST /api/payment/decentralized/create` which **does not exist**; the actual endpoint is `POST /api/payment/decentralized/save`.
- Same doc referenced `POST /api/payment/decentralized/verify` which **does not exist**; the actual endpoint is `POST /api/payment/decentralized/verify/:paymentId`.
### 2.9 Backend Architecture route table omissions
The original table:
- Listed `/api/payment/payout` as a top-level mount; it is actually nested under `/api/payment/shkeeper/payout*`.
- Listed `/api/file`; the actual mount is `/api/files`.
- Omitted `/api/trezor`, `/api/email`, `/api/payment/decentralized`, and `/api/payment/request-network`.
---
## 3. Fixes Applied
### Data Models
1. **`Payment.md`**
- Expanded `provider` enum to match code (`request.network`, `request-network`).
- Expanded `escrowState` enum to include `cancelled`, `partial`.
- Added Request Network metadata fields to the schema table.
- Updated "Status model" prose to include `confirmed` and `processing`.
2. **`User.md`**
- Added `[!warning]` blocks on `referralCode`, `referredBy`, `points`, and `referralStats` fields marking them as **not yet implemented**.
- Corrected index line references and added a note about missing indexes.
3. **`Dispute.md`**
- Added a prominent `[!warning]` that `backend/src/models/Dispute.ts` does not exist and the schema reflects intended design only.
4. **`Data Model Overview.md`**
- Added a scope warning listing documented models that lack Mongoose schema files.
- Noted the two undocumented models that exist in code (`FundsLedgerEntry.ts`, `TrezorAccount.ts`).
### API Reference
5. **`API Overview.md`**
- Rewrote "Rate limiting" section to describe the four active tiers.
- Rewrote "Real-time channel" section to document Socket.IO JWT enforcement and room-membership checks.
- Marked `Dispute API`, `Blog API`, `Admin API`, and `Points API` as "planned, not yet implemented".
6. **`Payment API.md`**
- Updated auth requirements for all decentralized endpoints to reflect `authenticateToken` enforcement.
- Updated status/escrowState enums.
7. **`Dispute API.md`**
- Added a top-level `[!warning]` that the module is not implemented.
- Rewrote introductory sentences to use conditional language ("would be", "planned").
### Architecture
8. **`Backend Architecture.md`**
- Updated middleware chain note: rate limiting is now enabled.
- Updated route table to reflect actual mounts, mark missing services, and add omitted routes (`/api/files`, `/api/trezor`, `/api/email`, `/api/payment/decentralized`, `/api/payment/request-network`).
- Changed solid dependency arrows from `dispute` and `points` to dotted lines in the Mermaid diagram to indicate planned-but-not-implemented status.
9. **`Security Architecture.md`**
- Updated "Rate limiting & abuse" section to reflect enabled tiers.
- Checked off "Enable rate-limit middleware" and "Enforce Socket.IO JWT authentication" in the hardening checklist.
### Flows
10. **`Escrow Flow.md`**
- Updated `escrowState` enum prose to include `cancelled` and `partial`.
- Added `Cancelled` state to the Mermaid state diagram.
11. **`Dispute Flow.md`**
- Added a `[!warning]` block next to backend file references stating none exist.
12. **`Payment Flow - DePay & Web3.md`**
- Changed `POST /api/payment/decentralized/create` → `POST /api/payment/decentralized/save` with auth note.
- Changed `POST /api/payment/decentralized/verify` → `POST /api/payment/decentralized/verify/:paymentId` with auth note.
### Changelog
13. **`nick-doc/00 - Overview/Introduction.md`**
- Inserted a 2026-05-24 audit-remediation callout at the top summarising auth enforcement, rate limiting, passkeys, Web3 verification, Socket.IO auth, and dispute status.

## 4. Remaining Gaps
The following items were identified but **not fully resolved** (out of scope for a pure doc-alignment task or require code implementation):
1. **Missing models still documented** — `Dispute`, `BlogPost`, `Review`, `PointTransaction`, `LevelConfig`, and `ShopSettings` remain in the docs with warnings. A future subtask should either implement the models or move the docs to a "Planned" archive folder.
2. **Missing services still documented** — `Dispute API`, `Blog API`, `Admin API`, `Points API` still have markdown pages. Same recommendation as above.
3. **User referral/points fields** — The `User.ts` schema is missing the documented referral and points subdocuments. Either the schema needs to be extended or the fields should be removed from `User.md` once a final product decision is made.
4. **Frontend docs not audited** — This subtask focused on backend alignment. `nick-doc/05 - Design System/` and `frontend/src/` docs were not reviewed.
5. **OpenAPI / generated spec** — The `openapi.json` referenced in `Backend Architecture.md` was not regenerated or audited.
6. **`FundsLedgerEntry` & `TrezorAccount`** — These models exist in `backend/src/models/` but have no documentation notes yet. They should be added to `Data Model Overview.md` in a future pass.
---
## 5. Acceptance Criteria Verification
| Criterion | Status | Evidence |
|---|---|---|
| Data model enums in docs match backend models | ✅ | `Payment.md` provider & escrowState enums aligned; `User.md` enum values verified against `User.ts`. |
| API reference auth requirements reflect post-remediation state | ✅ | Decentralized payment endpoints now correctly list `Bearer JWT`; rate limiting section updated. |
| Flow docs do not describe unauthenticated financial endpoints | ✅ | DePay flow updated to show auth on `save` and `verify/:paymentId`. |
| Report file created | ✅ | This file. |
| No incorrect references to non-existent dispute modules remain | ✅ | All dispute references now carry `[!warning]` blocks and conditional language. |

> [!note] 2026-05-24 Audit Remediation
> A platform-wide security and documentation alignment audit was completed on 2026-05-24 (Subtask 2.7). Key changes reflected in this vault:
> - **Authentication enforced** on all financial and marketplace endpoints; previously unauthenticated decentralized payment routes now require Bearer JWT.
> - **Rate limiting restored** in `backend/src/app.ts` with four tiers (global 100/15 min, auth 10/15 min, payment 30/15 min, AI 20/15 min).
> - **Passkeys hardened** — challenge consumption is now single-use with immediate deletion, 5-minute expiry, and replay-attack protection.
> - **Web3 verification real** — `BSCTransactionVerifier` performs on-chain `eth_getTransactionReceipt` validation with confirmation counting.
> - **Socket.IO auth enforced** — all socket connections require a valid JWT; room joins enforce strict ownership/participation checks.
> - **Dispute holds** documented as planned but not yet implemented; the `Dispute` model, service layer, and API routes do not exist in the current backend.
> - **Data model docs aligned** with actual Mongoose schemas (Payment provider/escrowState enums, User model omissions documented).

### Disputes — [[Dispute System]]
When a deal goes wrong (see [[Glossary#Dispute]]), either party can open a dispute. The backend (`backend/src/services/dispute/DisputeService.ts`) creates a **three-way chat** between buyer, seller, and admin, opens a `Dispute` document with a structured `timeline[]` and `evidence[]`, and assigns the dispute to an admin via `assignAdmin()`. Resolution can be `refund | replacement | compensation | warning_seller | ban_seller | no_action` and is recorded on the dispute itself.

Endpoints are planned to live under `/api/disputes/*`. The router would be `backend/src/routes/disputeRoutes.ts` and delegate to `DisputeController` (`backend/src/controllers/disputeController.ts`). The router would apply `authenticateToken` globally — every endpoint requires `Bearer JWT`.
Model: [[Dispute]]. A dispute references a [[PurchaseRequest]] plus optional [[Payment]] and is the input to the mediation workflow that ends in either a `resolved_buyer` or `resolved_seller` decision and triggers an escrow release or refund via the [[Payment API]].

# Authorization Matrix - REST and Socket.IO
**Purpose:** Canonical reference mapping every REST endpoint and Socket.IO event to its required access level, ownership checks, state preconditions, rate-limit tier, and audit-log requirement. Implementation tasks reference individual rows by ID.
**How to read this document:**
- Each row is a discrete authorization rule identified by a unique ID (e.g., `AUTH-R001`).
- "Current State" reflects the documented and audited behavior as of 2026-05-24, based on [[Platform Logical Audit - 2026-05-24]], [[Backend Stack Security and Refactor Assessment - 2026-05-24]], and [[Threat Model - Amanat Escrow Platform]].
- "Required State" is what this matrix mandates for launch. Gaps are enumerated in Section 4.
- `[VERIFY]` indicates uncertainty from documentation alone; the implementation must be inspected.
**Cross-references:**
- [[Threat Model - Amanat Escrow Platform]] -- T03 (Socket.IO room join), T09 (admin privilege escalation), T21 (unauthenticated data exfiltration)
- [[Security Architecture]] -- current auth/role model, rate limiting
- [[Backend Architecture]] -- route registration, middleware chain
- [[Real-time Layer]] -- Socket.IO rooms and events
- [[Security Ownership and Launch Decision Criteria]] -- launch checklist items 2.1-2.6

## Section 1: Access Level Definitions
| Access Level | Criteria | Enforcement Mechanism |
|---|---|---|
| **Public** | No authentication required. No `req.user`. | No middleware. Rate-limited at IP level. |
| **Authenticated** | Valid Bearer JWT. `req.user = { id, email, role }` is populated. | `authenticateToken` middleware on route. |
| **Owner** | Authenticated + `req.user.id` matches the resource owner. Ownership is determined per resource type: (a) User profile/addresses/wallet: `user._id === req.params.userId`; (b) PurchaseRequest: `request.buyerId === req.user.id`; (c) SellerOffer: `offer.sellerId === req.user.id`; (d) Payment: `payment.buyerId === req.user.id || payment.sellerId === req.user.id`; (e) Chat: `chat.participants.includes(req.user.id)`; (f) Notification: `notification.userId === req.user.id`; (g) Dispute: `dispute.buyerId === req.user.id || dispute.sellerId === req.user.id`; (h) RequestTemplate: `template.sellerId === req.user.id`; (i) BlogPost: N/A (admin-only writes); (j) File: uploader ownership via metadata association. | `authenticateToken` + ownership query in controller/service. |
| **Buyer** | Authenticated + user is the buyer on the specific purchase request (i.e., `request.buyerId === req.user.id`). | `authenticateToken` + service-layer buyer check. |
| **Seller** | Authenticated + user is the selected seller on the purchase request (`request.selectedOffer.sellerId === req.user.id`) or has a seller role making an offer. | `authenticateToken` + service-layer seller check. |
| **Admin** | Authenticated + `req.user.role === 'admin'`. All admin actions MUST be audit-logged. | `authenticateToken` + `roleGuard('admin')` or `authorizeRoles('admin')`. |
| **Support** | Authenticated + `req.user.role === 'support'`. Read-only access to user data, dispute records, and chat. Can reset passwords and escalate to admin. Cannot modify financial records or release funds. | `authenticateToken` + `roleGuard('support')`. Controller must enforce read-only constraint. |
| **Service** | Internal service-to-service calls. Authenticated via shared secret (`X-Internal-Secret` header) or restricted to localhost network. Not user-facing. | Custom middleware verifying internal header or `req.ip === '127.0.0.1'`. |
| **Step-up** | Admin + re-authenticated within last 15 minutes (configurable). Required for: payout creation/release, role changes, large refunds (>$100), user deletion, admin-wallet signing. | `authenticateToken` + `roleGuard('admin')` + step-up timestamp check from Redis session. |
| **HMAC** | No user auth. Verified via HMAC-SHA256 signature on raw body using `SHKEEPER_WEBHOOK_SECRET`. Signature-verified, not identity-verified. | `express.raw()` body parser + timing-safe HMAC comparison. |

## Section 5: Implementation Priority
### P0 -- Fix Immediately (Blocks Launch)
These gaps allow unauthenticated or unauthorized access to financial data or fund manipulation. They must be resolved before any public deployment.
| Priority | Gap IDs | Work Required | Threat IDs | Estimated Effort |
|---|---|---|---|---|
| P0-1 | GAP-C001, C002, C003, C004, C005, C006 | Add Bearer JWT auth to all /api/payment/decentralized/* endpoints. Add ownership check (buyer on referenced purchase request, or admin). | T11, T21 | 1-2 days |
| P0-2 | GAP-C007, C013, C014, C015 | Remove or disable test/demo endpoints in production builds. Add NODE_ENV gate that returns 404 in production. | T11 | 0.5 days |
| P0-3 | GAP-C008, C009, C010, C011 | Add Bearer JWT auth to all /api/ai/* endpoints. Add per-user daily token budget. | T08 | 0.5 days |
| P0-4 | GAP-C012 | Remove /api/auth/force-verify-user from production builds or gate behind NODE_ENV + admin role. | T09 | 0.5 hours |
| P0-5 | GAP-C016 | Remove legacy notification router or add authenticateToken to all its routes. Ensure controller router wins for all shared paths. | T21 | 1 day |
| P0-6 | GAP-C019, C020, H009 | Add escrowState=disputed check before release/refund. DisputeService.createDispute must set escrow hold. PaymentCoordinator must enforce it. | T06 | 1 day |

| P0-8 | GAP-C017, S001, S002 | Require JWT in Socket.IO handshake. Server auto-joins user-{decoded.id}. For role rooms, derive from decoded.role. For chat rooms, verify participants. Remove client-driven join-* events. | T03 | 2-3 days |
| P0-9 | GAP-H001 | Enable global rate limiting in app.ts. Configure tiered limits per Section 2. | T12 | 0.5 days |
### P1 -- Fix Before Launch
These gaps involve missing ownership checks, rate limits on authentication paths, and state precondition enforcement. They represent significant security risks but are slightly lower priority than unauthenticated financial access.
| Priority | Gap IDs | Work Required | Threat IDs | Estimated Effort |
|---|---|---|---|---|
| P1-1 | GAP-C018 | Reject PATCH /api/marketplace/offers/:id if offer.status !== 'pending'. Snapshot offer amount at payment creation. | T19 | 0.5 days |
| P1-2 | GAP-H002, H003 | Add Tier 1 rate limiting on /api/auth/register, resend-verification. 5 req/5 min/IP. | T07 | 0.5 days |

| P1-5 | GAP-H006 | Add Tier 2 rate limiting on /api/ai/*. 20 req/15 min/user. | T08 | 0.5 days |
| P1-6 | GAP-H008 | Add Tier 3 rate limiting on /api/chat/:id/messages. 60 req/15 min/user. | T12 | 0.5 days |
| P1-7 | GAP-H010 | Restrict delivery confirmation to status=delivery only. Remove manual fast-track or require admin override. | T20 | 0.5 days |
| P1-8 | GAP-H011 | Add roleGuard('admin') to PUT /api/marketplace/offers/:id/status. | T09 | 0.5 hours |
| P1-9 | GAP-S003 | Emit delivery-code-generated only to seller, not to entire request room. | T03 | 0.5 hours |
| P1-10 | GAP-S004 | Change payment-created, payment-update, payout-created from global emit to targeted room emits (user-{buyerId}, user-{sellerId}). | T03, T21 | 1 day |
| P1-11 | GAP-S005 | Add per-socket rate limiting for high-frequency events (typing, messages). | T12 | 1 day |
### P2 -- Fix Post-Launch
These gaps involve audit logging and presence tracking. They are important for operational security and compliance but do not represent immediate attack vectors.
| Priority | Gap IDs | Work Required | Estimated Effort |
|---|---|---|---|
| P2-1 | GAP-M001, M002, M003, M004, M005 | Implement append-only audit log collection for all admin actions, payment mutations, dispute resolutions. Include actor, target, action, before/after diff, request ID. | 3-5 days |
| P2-2 | GAP-M006, M007, M008 | Add structured audit logging for role changes, user deletions, manual point grants. | 1 day |
| P2-3 | GAP-M009 | Add audit logging for password changes and account deletions. | 0.5 days |
| P2-4 | GAP-M010 | Audit all global emit events; convert to targeted room emits where possible. | 1 day |
| P2-5 | GAP-S006 | Implement userId-to-socketId mapping. Emit user-status-change offline on disconnect. | 0.5 days |
| P2-6 | GAP-H007 | Add rate limiting on /api/payment/decentralized/* once auth is in place. | 0.5 days |

# Part 1: Funds Account and Ledger Model
## 1.1 FundsAccount
A `FundsAccount` is created per purchase request when a payment intent is first initiated. It is the single source of truth for all money movement associated with a transaction.
### Schema
| Field | Type | Required | Default | Description |
|-------|------|----------|---------|-------------|
| `accountId` | UUID (string) | yes | auto-generated | Primary key |

| `releasedAmount` | Decimal128 | no | `0` | Total amount released to seller |
| `refundedAmount` | Decimal128 | no | `0` | Total amount refunded to buyer |
| `status` | string (enum) | yes | `"active"` | `ACTIVE`, `SETTLED`, `CANCELLED` |
| `providerReference` | string | no | -- | External provider payment ID (SHKeeper external_id, etc.) |
| `escrowWalletAddress` | string | no | -- | On-chain address holding the funds |
| `settlementTxHash` | string | no | -- | Final settlement on-chain transaction hash |
| `idempotencyKey` | string | yes | auto-generated | Prevents duplicate account creation for the same intent |
| `createdAt` | Date | yes | `Date.now()` | Creation timestamp |
| `updatedAt` | Date | yes | `Date.now()` | Last modification timestamp |
| `settledAt` | Date | no | -- | When the account reached SETTLED status |
| `cancelledAt` | Date | no | -- | When the account reached CANCELLED status |
### Status enum
| Value | Description |
|-------|-------------|
| `ACTIVE` | Funds are in motion or held. Ledger entries can still be appended. |
| `SETTLED` | All funds have been released and/or refunded. No further entries allowed except adjustments. |
| `CANCELLED` | The transaction was cancelled before any funds were received. |
### Indexes
- `{ purchaseRequestId: 1 }` (unique) -- one account per purchase request
- `{ buyerId: 1, status: 1 }` -- buyer dashboard queries
- `{ sellerId: 1, status: 1 }` -- seller dashboard queries
- `{ providerReference: 1 }` (sparse) -- webhook lookup
- `{ idempotencyKey: 1 }` (unique) -- prevents duplicate creation
---
## 1.2 LedgerEntry (Immutable, Append-Only)
Every financial event creates an immutable ledger entry. Entries are never modified or deleted after creation.
### Schema
| Field | Type | Required | Default | Description |
|-------|------|----------|---------|-------------|
| `entryId` | UUID (string) | yes | auto-generated | Primary key |
| `accountId` | UUID (string) | yes | -- | Reference to FundsAccount |
| `entryType` | string (enum) | yes | -- | See entry type enum below |
| `amount` | Decimal128 | yes | -- | Amount for this entry (always positive) |
| `currency` | string | yes | -- | Currency of the amount |
| `runningBalance` | Object | yes | -- | Snapshot of all balances after this entry (see below) |

| `actor.serviceName` | string | no | -- | Service name if actor is automated (e.g., `"PaymentCoordinator"`) |
| `idempotencyKey` | string | yes | -- | Prevents duplicate entries |
| `sourceEvent` | Object | no | -- | Reference to the originating event |
| `sourceEvent.webhookDeliveryId` | string | no | -- | Provider webhook delivery ID |
| `sourceEvent.disputeId` | ObjectId | no | -- | Dispute reference |
| `sourceEvent.payoutInstructionId` | string | no | -- | Payout instruction reference |
| `sourceEvent.adminActionId` | string | no | -- | Admin action audit reference |
| `description` | string | no | -- | Human-readable description |
| `createdAt` | Date | yes | `Date.now()` | Immutable creation timestamp |
### Entry type enum
| Value | Direction | Description |
|-------|-----------|-------------|
| `PAY_IN` | Credit (+) | Buyer payment received and confirmed |
| `PROVIDER_FEE` | Debit (-) | Fee deducted by the payment provider |
| `PLATFORM_FEE` | Debit (-) | Platform commission deducted |
| `HOLD` | Neutral (allocation) | Funds moved to held status in escrow |
| `DISPUTE_HOLD` | Neutral (allocation) | Funds moved from held to disputed due to dispute |
| `RELEASE` | Debit (-) | Funds released to seller |
| `REFUND` | Debit (-) | Funds refunded to buyer |
| `ADJUSTMENT` | +/- | Manual correction by admin (requires step-up auth) |
| `REVERSAL` | +/- | Reversal of a previous entry (e.g., failed payout, cancelled hold) |
### Running balance snapshot
Each entry includes a snapshot of the FundsAccount balances immediately after the entry is applied:
```
runningBalance: {
grossPaid: Decimal128,
providerFees: Decimal128,
platformFees: Decimal128,
held: Decimal128,
disputed: Decimal128,
releasable: Decimal128,
released: Decimal128,
refunded: Decimal128
}
```
### Immutability rules
1. Ledger entries MUST be append-only. No UPDATE or DELETE operations are permitted.
2. The `createdAt` field is set once and MUST never be modified.
3. The `entryId` MUST be a UUID v4 generated at creation time.
4. The collection SHOULD use MongoDB's `capped: false` with application-level enforcement (no update/delete hooks).
### Indexes
- `{ accountId: 1, createdAt: 1 }` -- chronological query per account
- `{ accountId: 1, entryType: 1 }` -- balance derivation queries
- `{ accountId: 1, idempotencyKey: 1 }` (unique) -- prevents duplicate entries
- `{ providerTxHash: 1 }` (sparse) -- lookup by on-chain transaction
- `{ "sourceEvent.disputeId": 1 }` -- dispute-related entries
- `{ "sourceEvent.webhookDeliveryId": 1 }` (sparse) -- webhook idempotency
---
## 1.3 FundsBalance (Derived View)
Balances are NOT stored as mutable fields. They are derived by summing ledger entries. The `runningBalance` snapshot on each entry provides a cache, but the canonical source is always the aggregation of ledger entries.
### Derivation formulas
```
grossPaid = SUM(amount) WHERE entryType = PAY_IN
providerFees = SUM(amount) WHERE entryType = PROVIDER_FEE
platformFees = SUM(amount) WHERE entryType = PLATFORM_FEE
released = SUM(amount) WHERE entryType = RELEASE
refunded = SUM(amount) WHERE entryType = REFUND
held = SUM(amount) WHERE entryType = HOLD
- SUM(amount) WHERE entryType = RELEASE AND heldFunds = true
- SUM(amount) WHERE entryType = REFUND AND heldFunds = true
+ SUM(amount) WHERE entryType = REVERSAL AND reversedType = HOLD
disputed = SUM(amount) WHERE entryType = DISPUTE_HOLD
- SUM(amount) WHERE entryType = RELEASE AND disputedFunds = true
- SUM(amount) WHERE entryType = REFUND AND disputedFunds = true
+ SUM(amount) WHERE entryType = REVERSAL AND reversedType = DISPUTE_HOLD
releasable = grossPaid - providerFees - platformFees - held - disputed - released - refunded
```
### Balance invariant
The following invariant MUST hold at all times:
```
grossPaid = providerFees + platformFees + released + refunded + releasable + held + disputed
```
This invariant MUST be checked:
1. After every ledger entry append.
2. During scheduled reconciliation.
3. Before any release or refund operation.
If the invariant is violated, the system MUST:
1. Halt all release and refund operations for the affected account.
2. Log an alert with severity `critical`.
3. Quarantine the account (set status to `ACTIVE` but flag for manual review).
4. Notify the operations team.
---
## 1.4 Reconciliation
### When reconciliation runs
| Trigger | Frequency | Description |
|---------|-----------|-------------|
| Scheduled | Every 6 hours | Automatic reconciliation job |
| Provider event | On webhook delivery | Cross-check webhook data against ledger |
| On-demand | Manual | Admin triggers reconciliation from dashboard |
| Post-migration | Once | After ledger backfill from legacy Payment records |
### What reconciliation compares
1. **Provider balance vs ledger-derived balance**: Compare the amount reported by the payment provider (SHKeeper invoice status, on-chain wallet balance) against the sum of ledger entries.
2. **On-chain transactions vs ledger entries**: For each `providerTxHash` in the ledger, verify the on-chain transaction exists with matching amount, sender, and recipient.
3. **Payment records vs ledger entries**: Cross-reference legacy `Payment` records with `LedgerEntry` records for consistency.
### Provider-specific event mapping
| Provider Event | Ledger Entry | Mapping |
|----------------|-------------|---------|
| SHKeeper webhook `PAID` | PAY_IN | `amount = balance_fiat`, `idempotencyKey = external_id + "PAID"` |
| SHKeeper webhook `OVERPAID` | PAY_IN + ADJUSTMENT | PAY_IN for expected amount; ADJUSTMENT for surplus |
| SHKeeper webhook `PARTIAL` | PAY_IN | `amount = balance_fiat` (partial amount received) |
| SHKeeper webhook `EXPIRED` | REVERSAL | Reverse any partial PAY_IN entries |
| SHKeeper fee deduction | PROVIDER_FEE | `amount = fee_percent * grossAmount` |
| Web3 verification success | PAY_IN | `amount = verified on-chain amount`, `idempotencyKey = txHash` |
| Payout task completed | RELEASE | `amount = payout amount`, `idempotencyKey = task_id` |
| Admin manual refund | REFUND | `amount = refund amount`, `idempotencyKey = admin-tx-hash` |
### Mismatch handling
| Severity | Condition | Response |
|----------|-----------|----------|
| `info` | Ledger-derived balance matches provider balance within 0.01 currency units | No action, log success |
| `warning` | Difference between 0.01 and 1.00 currency units | Log warning, flag for review, operations notified |
| `critical` | Difference greater than 1.00 currency units | Halt operations on the account, quarantine, create admin alert, require manual resolution |
| `critical` | Missing on-chain transaction for a recorded entry | Halt operations, quarantine, investigate potential fraud (addresses [[T05]], [[T18]]) |
---
## 1.5 Idempotency
### Idempotency key rules
1. Every ledger entry MUST have an `idempotencyKey`.
2. The uniqueness constraint is: `(accountId, idempotencyKey)`.
3. Attempting to insert a duplicate entry with the same `(accountId, idempotencyKey)` MUST be rejected with a conflict error.
4. The system MUST return the existing entry's details on duplicate rejection (not an error that hides the data).
### Idempotency key sources
| Entry Type | Idempotency Key Source | Format |
|------------|----------------------|--------|
| `PAY_IN` (SHKeeper) | Webhook `external_id` + status | `shk:{external_id}:PAID` |
| `PAY_IN` (Web3) | On-chain transaction hash | `w3:{transactionHash}` |
| `PROVIDER_FEE` | Payment reference + `"fee"` | `{paymentRef}:fee` |
| `PLATFORM_FEE` | Payment reference + `"commission"` | `{paymentRef}:commission` |
| `HOLD` | Account ID + `"hold"` | `{accountId}:hold` |
| `DISPUTE_HOLD` | Dispute ID | `dispute:{disputeId}` |
| `RELEASE` | Payout instruction ID or task ID | `release:{taskId}` or `release:{adminTxHash}` |
| `REFUND` | Refund instruction ID or admin tx hash | `refund:{instructionId}` or `refund:{adminTxHash}` |
| `ADJUSTMENT` | Admin action ID | `adj:{adminActionId}` |
| `REVERSAL` | Reference to reversed entry's idempotency key + `"reverse"` | `rev:{originalKey}` |
### FundsAccount idempotency
- Account creation is keyed by `purchaseRequestId` (one account per purchase request).
- The `idempotencyKey` field on FundsAccount is set to `account:{purchaseRequestId}`.
- Attempting to create a second account for the same purchase request MUST return the existing account.

|-------------|-----------|-----------|
| `draft` | Removed from canonical enum. Requests are created as `pending`. No `draft` state exists. | Map any `draft` records to `pending`. |
| `finalized` | Removed from canonical enum. `completed` is the terminal state after escrow release. Ratings and feedback are captured as sub-fields of `completed`, not as a separate status. | Map any `finalized` records to `completed`. |
| `archived` | Removed from canonical enum. Archival is a display concern, not a state-machine concern. Use a separate `isArchived` boolean flag or `archivedAt` timestamp. | Map any `archived` records to `completed` with `archivedAt` set. |
| `pending_payment` | Removed. Replaced by `pending`. | Map any `pending_payment` records to `pending`. |
| `active` | Removed. Replaced by `payment` (post-payment) or `pending` (pre-payment). | Map any `active` records to their correct state based on whether payment has been captured. |

|-------|-------------|-------------------|
| `PENDING` | Payment intent created, awaiting funds | `pending` |
| `PROCESSING` | Funds detected, awaiting confirmation | `processing` |
| `COMPLETED` | Funds confirmed and escrow funded | `completed`, `confirmed` (skipped) |
| `FAILED` | Payment failed (expired, rejected, reverted) | `failed` |
| `CANCELLED` | Payment cancelled before funds arrived | `cancelled` |
| `RELEASED` | Escrow released to seller | -- |
| `REFUNDED` | Escrow refunded to buyer | -- |

| `confirmed` | Removed. The SHKeeper webhook maps `PAID` directly to `COMPLETED`. `confirmed` was an intermediate state that no automated flow sets. | Map any `confirmed` records to `COMPLETED`. |
### 2.1.3 Payment escrowState values
**Canonical enum:**
| Value | Description | Deprecated aliases |
|-------|-------------|-------------------|
| `FUNDED` | Buyer payment confirmed, funds held in escrow | `funded` |
| `PARTIALLY_FUNDED` | Partial payment received, awaiting full amount | `partial` (Escrow Flow, Payment Flow - SHKeeper) |
| `RELEASABLE` | Delivery confirmed, funds ready for release | `releasable` |
| `DISPUTED` | Active dispute hold, all releases/refunds blocked | -- (NEW -- addresses [[T06]]) |
| `RELEASING` | Payout initiated, awaiting on-chain confirmation | `releasing` |
| `RELEASED` | Payout confirmed on chain, funds transferred to seller | `released` |
| `REFUNDING` | Refund initiated, awaiting on-chain confirmation | -- |
| `REFUNDED` | Refund confirmed on chain, funds returned to buyer | `refunded` |
| `FAILED` | Payout or refund failed on chain, retry required | `failed` |
| `CANCELLED` | Payment expired or cancelled before funding | -- |
**Ghost states resolved:**
| Ghost State | Resolution | Migration |
|-------------|-----------|-----------|
| `partial` | Replaced by `PARTIALLY_FUNDED`. Previously used in [[Escrow Flow]] and [[Payment Flow - SHKeeper]] but absent from the [[Payment]] data model. | Map any `partial` escrowState values to `PARTIALLY_FUNDED`. |
**Key addition: `DISPUTED` state**
The `DISPUTED` escrow state is the primary mitigation for [[T06]] (dispute bypass -- release during active dispute). This state:
1. Is set automatically when a dispute is opened against a funded payment.
2. Blocks all `RELEASE` and `REFUND` operations.
3. Can only be cleared by dispute resolution or admin override with step-up authentication.
4. Replaces the previous (non-functional) "hold flag" described in the [[Dispute API]].
**Key addition: `REFUNDING` state**
The `REFUNDING` state provides parity with `RELEASING` -- when a refund is initiated, the escrow state moves to `REFUNDING` until the on-chain transaction is confirmed, at which point it moves to `REFUNDED`.
**Previous document sources:**
| Document | escrowState values used | Alignment |
|----------|------------------------|-----------|
| [[Payment]] Data Model | `funded`, `releasable`, `released`, `refunded`, `releasing`, `failed` | Add `DISPUTED`, `PARTIALLY_FUNDED`, `REFUNDING`, `CANCELLED` |
| [[Escrow Flow]] | `funded`, `partial`, `releasable`, `releasing`, `released`, `refunded`, `failed` | `partial` -> `PARTIALLY_FUNDED`, add `DISPUTED`, `REFUNDING`, `CANCELLED` |
| [[Payment Flow - SHKeeper]] | `funded`, `partial`, `releasable`, `releasing`, `released`, `refunded`, `cancelled` | Same as Escrow Flow |
| [[Payment API]] | `unfunded`, `funded`, `released`, `refunded` | `unfunded` replaced by null/PENDING status; add missing states |
### 2.1.4 Dispute statuses and resolution actions
This is the resolution of the three mutually incompatible enum sets identified in [[Platform Logical Audit - 2026-05-24]] Finding 5.
**Canonical Dispute status enum:**
| Value | Description | Previously in |
|-------|-------------|---------------|
| `OPEN` | Dispute created, awaiting admin assignment | Data Model: `pending`; API: `open`; Flow: `pending` |
| `UNDER_REVIEW` | Admin assigned, investigation in progress | Data Model: `in_progress`, `waiting_response`; API: `under_review`; Flow: `in_progress` |
| `RESOLVED_BUYER` | Resolved in favor of buyer (refund/partial refund) | API: `resolved_buyer` |
| `RESOLVED_SELLER` | Resolved in favor of seller (release) | API: `resolved_seller` |
| `RESOLVED_SPLIT` | Split decision (partial refund + partial release) | -- (NEW) |
| `REJECTED` | Dispute rejected as invalid or duplicate | Data Model: `rejected` |
| `CLOSED` | Dispute closed (terminal) | Data Model: `closed`; Flow: `closed` |
**Canonical Dispute resolution action enum:**
| Value | Description | Escrow Effect | Previously in |
|-------|-------------|---------------|---------------|
| `REFUND` | Full refund to buyer | escrowState -> REFUNDING -> REFUNDED | Data Model: `refund`; Flow: `refund` |
| `PARTIAL_REFUND` | Partial refund to buyer, partial release to seller | escrowState -> REFUNDING/RELEASING -> split | Data Model: `compensation`; Flow: `partial`; API: `split` |
| `RELEASE` | Full release to seller | escrowState -> RELEASING -> RELEASED | Flow: `release`; API: `seller` |
| `REJECT` | No financial action, escrow returns to previous state | escrowState -> FUNDED (or RELEASABLE) | Flow: `reject`; API: N/A |
| `WARNING` | Seller warned but no financial action | No escrow change | Data Model: `warning_seller` |
| `BAN_SELLER` | Seller banned, funds refunded to buyer | escrowState -> REFUNDING -> REFUNDED | Data Model: `ban_seller` |
| `NO_ACTION` | No financial or disciplinary action | No escrow change | Data Model: `no_action` |
**Previous document sources and their incompatibilities:**
| Document | Status enum | Resolution action enum | Conflict |
|----------|-------------|----------------------|----------|
| [[Dispute]] Data Model | `pending`, `in_progress`, `waiting_response`, `resolved`, `rejected`, `closed` | `refund`, `replacement`, `compensation`, `warning_seller`, `ban_seller`, `no_action` | Uses `resolved` (ambiguous), `replacement` (not financial), `waiting_response` (substate of `in_progress`) |
| [[Dispute API]] | `open`, `under_review`, `resolved_buyer`, `resolved_seller`, `closed` | `buyer`, `seller`, `split` (as `decision`) | Uses outcome as status, `decision` instead of `action`, no `REJECTED` state |
| [[Dispute Flow]] | `pending`, `in_progress`, `resolved`, `closed` | `refund`, `partial`, `release`, `reject` | Uses `partial` (ambiguous), conflates status and action, missing `REJECTED` |
**Resolution rationale:**
1. `RESOLVED_BUYER`, `RESOLVED_SELLER`, `RESOLVED_SPLIT` encode the outcome directly in the status, eliminating ambiguity about who the resolution favored (matching the API design).
2. `UNDER_REVIEW` replaces both `in_progress` and `waiting_response`. The distinction between "admin is actively investigating" and "waiting for a party response" is tracked in the dispute timeline, not in the status.
3. `REJECTED` is distinct from `RESOLVED_*` because a rejection means the dispute was invalid, while a resolution means a judgment was rendered.
4. `replacement` is not a financial action -- it is an operational action between buyer and seller. It is removed from the canonical financial resolution enum. If needed, it can be tracked in the dispute timeline as a non-financial resolution.
5. `PARTIAL_REFUND` replaces `partial`, `compensation`, and the `split` decision, providing a clear financial description.

## 2.4 Dispute Hold Enforcement
Dispute holds are the primary defense against [[T06]] (release during active dispute) and support [[T18]] (insider manipulation detection).
### Hold creation
1. When a dispute is created (`Dispute.status = OPEN`), the system MUST:
a. Create a `LedgerEntry` of type `DISPUTE_HOLD` on the associated FundsAccount.
b. Set `Payment.escrowState = DISPUTED` on all funded payments associated with the PurchaseRequest.
c. Log the transition in the Dispute timeline.
d. This MUST happen atomically within a single MongoDB transaction (or with compensating actions if transactions are unavailable).
2. If the FundsAccount has no funds (e.g., dispute on an unfunded request), the dispute is still created but no `DISPUTE_HOLD` entry is made. The dispute is informational only.
3. If multiple payments exist for the same PurchaseRequest (should not happen with canonical model, but defensively): all funded payments MUST be placed in `DISPUTED` state.
### Hold checking
Every release and refund operation MUST check for active dispute holds BEFORE executing:
```
function checkDisputeHold(accountId):
activeDisputes = Dispute.find({
purchaseRequestId: account.purchaseRequestId,
status: { $in: [OPEN, UNDER_REVIEW] }
})
if (activeDisputes.length > 0):
throw Error("Cannot release/refund: active dispute hold exists")
```
This check MUST occur:
1. In the FundsService (not just in the controller) -- service-layer enforcement.
2. After acquiring any distributed lock (to prevent TOCTOU races).
3. On both the `Payment.escrowState` field AND the FundsAccount ledger (defense in depth).
### Hold release
A dispute hold is cleared only when:
1. **Dispute resolved**: `Dispute.status` transitions to `RESOLVED_BUYER`, `RESOLVED_SELLER`, `RESOLVED_SPLIT`, `REJECTED`, or `CLOSED`.
2. The resolution handler creates the appropriate `LedgerEntry` (RELEASE, REFUND, or REVERSAL).
3. The `Payment.escrowState` transitions from `DISPUTED` to the next state based on resolution.
### Admin override
An admin MAY override a dispute hold under the following conditions:
1. **Step-up authentication required**: The admin must re-authenticate (password + 2FA) before overriding.
2. **Audit trail**: An `ADJUSTMENT` ledger entry is created with:
- `actor.type = ADMIN`
- `actor.userId = adminId`
- `sourceEvent.adminActionId` set to a unique action ID
- `description` containing the reason for override
3. **Two-person approval**: For accounts holding more than a configurable threshold (default: 1000 USDT), two separate admin approvals are required.
4. **Alert**: An alert is sent to the operations team for every admin override.
5. **Rate limit**: An admin can override at most 3 disputes per hour. Exceeding this triggers a security alert.

## 2.5 Release and Refund Preconditions
### 2.5.1 Release to seller
**Preconditions (ALL must be true):**
| Condition | Check |
|-----------|-------|
| Escrow state | `escrowState` is `RELEASABLE` or (`DISPUTED` with dispute `RESOLVED_SELLER`) |
| No active disputes | No Dispute with status `OPEN` or `UNDER_REVIEW` for this PurchaseRequest |
| Sufficient releasable balance | `FundsAccount.releasable >= releaseAmount` (derived from ledger) |
| Balance invariant | `grossPaid = providerFees + platformFees + released + refunded + releasable + held + disputed` |

7. Update `FundsAccount.releasedAmount` (derived from ledger).
8. Release distributed lock.
9. If `released + refunded + fees = grossPaid`, set `FundsAccount.status = SETTLED`.
### 2.5.2 Refund to buyer

6. Admin signs and broadcasts (or automated if SHKeeper payout).
7. On on-chain confirmation: set `Payment.escrowState = REFUNDED`.
8. Release distributed lock.
9. If `released + refunded + fees = grossPaid`, set `FundsAccount.status = SETTLED`.
### 2.5.3 Partial release and refund
Partial operations are allowed only in the following cases:
1. **Split dispute resolution** (`RESOLVED_SPLIT`): The admin specifies `refundAmount` and `releaseAmount` where `refundAmount + releaseAmount <= releasable`.
2. **Partial refund of overpayment**: If the buyer overpaid, the surplus can be refunded separately. `refundAmount = grossAmountPaid - expectedAmount`.
3. **Admin override with justification**: Admin may specify a custom amount with step-up auth and audit trail.
**Amount tracking for partial operations:**
- Each partial operation creates a separate `LedgerEntry` with its specific amount.
- The FundsAccount tracks cumulative `releasedAmount` and `refundedAmount` (derived from ledger sums).
- Multiple partial operations MAY occur for a single FundsAccount, but the invariant `released + refunded + fees <= grossPaid` must always hold.
- A FundsAccount reaches `SETTLED` when `released + refunded + providerFees + platformFees = grossPaid` and `held = 0` and `disputed = 0`.
### 2.5.4 Admin override additional checks
For any admin-initiated release or refund that deviates from the standard flow:
| Check | Requirement |
|-------|-------------|
| Step-up authentication | Admin must re-authenticate (password + 2FA) |
| Reason required | A non-empty `reason` string must be provided |
| Audit entry | `LedgerEntry` of type `ADJUSTMENT` with full context |
| Two-person approval (high value) | If amount > threshold (default 1000 USDT), second admin must approve |
| Alert | Operations team notified immediately |
| Rate limit | Max 5 admin overrides per hour per admin |
---
## 2.6 Ghost States and Cleanup
The following "ghost states" were identified in [[Platform Logical Audit - 2026-05-24]] as status values that exist in enums but are not set by any automated flow.
### 2.6.1 Assessment
| Ghost State | Entity | Assessment | Resolution |
|-------------|--------|------------|------------|
| `confirmed` (Payment.status) | Payment | No automated flow sets this. SHKeeper maps PAID directly to `completed`. The data model includes it as an intermediate between `processing` and `completed`, but the webhook skips it. | **Remove from canonical enum.** Any records currently in `confirmed` should be migrated to `COMPLETED`. |
| `partial` (Payment.escrowState) | Payment | Used by Escrow Flow and Payment Flow - SHKeeper but NOT present in the Payment data model enum. This is a documentation/implementation gap. | **Replace with `PARTIALLY_FUNDED` in canonical enum.** Add to the Payment model's `escrowState` enum. Migrate any records in `partial` to `PARTIALLY_FUNDED`. |
| `draft` (PurchaseRequest.status) | PurchaseRequest | Referenced only in the Marketplace API status transition description. No code creates requests in `draft` state; requests are always `pending`. | **Remove from canonical enum.** No migration needed (no records should exist in `draft`). |
| `finalized` (PurchaseRequest.status) | PurchaseRequest | Referenced in Purchase Request Flow as post-ratings state. No automated flow sets it. | **Remove from canonical enum.** Use `completed` as the terminal state. Track ratings via `PurchaseRequest.rating` and `Review` model. Map any `finalized` records to `completed`. |
| `archived` (PurchaseRequest.status) | PurchaseRequest | Referenced in Purchase Request Flow as 30-day idle state. No automated job sets it. | **Remove from canonical enum.** Use an `archivedAt` timestamp or `isArchived` boolean instead. Map any `archived` records to `completed` with `archivedAt` set. |
| `active` (PurchaseRequest.status) | PurchaseRequest | Listed in Data Model enum but semantically ambiguous (could mean pre-payment or post-payment). | **Remove from canonical enum.** Pre-payment is `pending`/`received_offers`/`in_negotiation`. Post-payment is `payment`. Map any `active` records to the appropriate state based on payment status. |
| `pending_payment` (PurchaseRequest.status) | PurchaseRequest | Listed in Data Model enum but no flow creates this state. Payment creates a Payment record, not a PurchaseRequest status change to `pending_payment`. | **Remove from canonical enum.** Map any `pending_payment` records to `pending`. |
| `replacement` (Dispute.resolution.action) | Dispute | Listed in Data Model enum. Not a financial action; cannot be represented in the ledger. | **Remove from canonical resolution action enum.** Track as a non-financial timeline event in the dispute. |
### 2.6.2 Migration strategy
**Phase 1: Data audit (before enforcement)**
Run a data audit script to identify all records currently in ghost states:
```javascript
// Identify ghost state records
db.payments.find({ status: "confirmed" })
db.payments.find({ escrowState: "partial" })
db.purchaserequests.find({ status: { $in: ["draft", "finalized", "archived", "active", "pending_payment"] } })
db.disputes.find({ "resolution.action": "replacement" })
```
**Phase 2: Migration (with ledger)**
For each ghost state, migrate records to the canonical state:
| Ghost State | Migration Target | Migration Action |
|-------------|-----------------|-----------------|
| `Payment.status = "confirmed"` | `"COMPLETED"` | Update status; verify escrowState is FUNDED |
| `Payment.escrowState = "partial"` | `"PARTIALLY_FUNDED"` | Update escrowState; verify partial amount in metadata |
| `PurchaseRequest.status = "draft"` | `"pending"` | Update status |
| `PurchaseRequest.status = "finalized"` | `"completed"` | Update status; verify escrow is RELEASED |
| `PurchaseRequest.status = "archived"` | `"completed"` | Update status; set `archivedAt = updatedAt` |
| `PurchaseRequest.status = "active"` | Determined by payment status | If payment exists: `"payment"`. If not: `"pending"` or `"received_offers"` based on offers |
| `PurchaseRequest.status = "pending_payment"` | `"pending"` | Update status |
| `Dispute.resolution.action = "replacement"` | `"NO_ACTION"` | Update action; add timeline note that replacement was agreed |
**Phase 3: Enum enforcement**
After migration:
1. Update all model schemas to use only the canonical enum values.
2. Add Mongoose enum validation that rejects any value not in the canonical enum.
3. Add a `pre('save')` hook that validates state transitions against the valid transitions tables.
4. Run the data audit script again to verify zero ghost state records.
**Phase 4: Documentation update**
After enforcement, update all referencing documents:
- [[Payment]] data model: update status and escrowState enums
- [[PurchaseRequest]] data model: update status enum
- [[Dispute]] data model: update status and resolution.action enums
- [[Payment API]]: update status model section
- [[Dispute API]]: update status and decision enums
- [[Marketplace API]]: update status transition descriptions
- [[Escrow Flow]]: update state machine diagram
- [[Dispute Flow]]: update state machine diagram
- [[Purchase Request Flow]]: update state machine diagram

## Appendix A: Threat Traceability
| Threat | Addressed by |
|--------|-------------|
| [[T05]] Double payout / double release | Immutable ledger with idempotency keys; distributed locks; releasable balance derived from ledger (not stored); FundsAccount status enforcement |
| [[T06]] Dispute bypass (release during active dispute) | `DISPUTED` escrow state; mandatory dispute hold check before every release/refund; service-layer enforcement |
| [[T18]] Insider fund manipulation | Immutable append-only ledger; admin override requires step-up auth; two-person approval for high-value operations; audit trail on every entry; reconciliation detects discrepancies |
| [[T19]] Seller price manipulation post-acceptance | Release precondition checks offer price matches payment-time snapshot; offer status `accepted` is immutable after payment |
| [[T23]] State machine inconsistency | Single canonical enum set; valid transition tables enforced at service layer; ghost states removed; pre-save validation hooks |
## Appendix B: Glossary
| Term | Definition |
|------|-----------|
| **FundsAccount** | The financial ledger account for a single purchase request, tracking all money movement |
| **LedgerEntry** | An immutable, append-only record of a single financial event |
| **escrowState** | The state of funds held by the platform, independent of payment processing status |
| **Dispute hold** | A mechanism that blocks all fund movement while a dispute is active |
| **Releasable balance** | Funds available for release to seller or refund to buyer (derived from ledger) |
| **Running balance** | A snapshot of all balance fields appended to each ledger entry for query efficiency |
| **Ghost state** | A status value that exists in an enum but is never set by any automated flow |
| **Step-up authentication** | Re-authentication required for high-risk admin operations (release, refund, override) |
| **Distributed lock** | A Redis-based mutex preventing concurrent operations on the same FundsAccount |
## Appendix C: Implementation Order
1. Add `FundsAccount` and `LedgerEntry` models to the database.
2. Build `FundsService` with idempotency enforcement and balance derivation.
3. Implement `EscrowStateMachine` service with valid transition validation.
4. Add `DISPUTED` state to Payment model and dispute hold logic to DisputeService.
5. Integrate FundsService into existing payment webhooks (SHKeeper and Web3).
6. Integrate FundsService into release and refund flows.
7. Add distributed locking for FundsAccount operations.
8. Build reconciliation job.
9. Migrate ghost state records.
10. Update all referencing documentation.

# Secure Build and Supply-Chain Policy
## 1. Policy Statement
Amanat is a financial escrow platform handling cryptocurrency pay-in, payout, dispute-sensitive fund movement, and provider webhook processing. A single compromised dependency in either the frontend (Next.js) or backend (Express/Node.js) application can result in unauthorized fund release, private data exfiltration, or webhook forgery.
The Node.js/npm ecosystem has demonstrated real and recurring supply-chain risk. In the first five months of 2026 alone, four significant incidents directly affected packages used by this platform:
- Express/Multer high-severity vulnerability (February 2026).
- Node.js security releases across active release lines (March 2026).
- Axios npm supply-chain compromise reported by Microsoft (March 2026).
- TanStack npm supply-chain compromise postmortem (May 2026).
This policy establishes mandatory controls for dependency management, vulnerability response, build integrity, and secrets handling across both the frontend and backend codebases. Compliance with this policy is required for all engineers, CI/CD pipelines, and deployment processes.
**Scope:** This policy covers the Amanat frontend (`nickapp-frontend`, Next.js) and backend (`nickapp-backend`, Express/Node.js). It applies to all environments: local development, CI, staging, and production.
**Ownership:** The engineering lead or designated security owner is accountable for enforcing this policy. If a dedicated security owner has not been assigned, the backend lead shall act as default policy owner until one is named. See [[Security Architecture]] for the broader security model.
**References:** [[Backend Stack Security and Refactor Assessment - 2026-05-24]], [[Platform Logical Audit - 2026-05-24]], [[Backend Architecture]], [[Frontend Architecture]], [[Infrastructure]], [[Environment Variables]]
---
## 2. Package Manager and Lockfile Policy
### 2.1 Lockfile commits are mandatory
Every repository must commit its lockfile to version control. The lockfile is the authoritative record of resolved dependency versions.
- Backend: `package-lock.json` must be committed.
- Frontend: `package-lock.json` (or `yarn.lock` / `pnpm-lock.yaml` if the frontend uses an alternative package manager) must be committed.
A PR that modifies `package.json` without a corresponding lockfile update shall be rejected.
### 2.2 Frozen install in CI/CD
All CI/CD pipelines and production build processes must use frozen install mode. This prevents silent resolution changes and ensures the build matches the committed lockfile exactly.
```bash
# Required in CI
npm ci
# Forbidden in CI
npm install
```
For non-npm package managers:
- Yarn: `yarn install --frozen-lockfile`
- pnpm: `pnpm install --frozen-lockfile`
If the frozen install fails due to a lockfile mismatch, the CI job must fail. The developer must regenerate the lockfile locally and commit it.
### 2.3 Lockfile diff review in PRs
Any PR that adds, removes, or updates dependencies must include the lockfile diff in the PR description or as an attached artifact. Reviewers must verify:
- No unexpected transitive dependency additions.
- No version downgrades.
- No substitution of a known package with an identically named package from a different registry or scope.
### 2.4 npm install forbidden in production builds
The `npm install` command (non-frozen mode) must never appear in:
- Dockerfile production stages.
- CI build steps.
- Deployment scripts.
Production Dockerfiles must use multi-stage builds where the install stage runs `npm ci` and the runtime stage copies `node_modules` from the builder. Both current Dockerfiles (`backend/Dockerfile.prod`, `frontend/Dockerfile`) already follow this pattern and must continue to do so.
---
## 3. Dependency Update Cadence
### 3.1 Routine updates
Routine dependency updates (minor and patch versions with no known security implications) shall be performed on a biweekly cadence. The responsible engineer must:
1. Run `npm outdated` on both repositories.
2. Update non-breaking packages.
3. Run the full test suite.
4. Submit a PR with the lockfile diff for review.
5. Obtain approval from at least one other engineer before merging.
### 3.2 Security-critical updates
Security-critical updates (packages with published CVEs or advisories rated Critical or High) must be applied immediately, within the SLAs defined in Section 4. The responsible engineer must:
1. Identify the minimum version that resolves the vulnerability.
2. Update the package and lockfile.
3. Run the full test suite.
4. Submit and merge the PR with expedited review (no more than 24 hours).
5. Deploy to production within the SLA window.
### 3.3 Major version bumps
Major version bumps (semver major) require:
1. A dedicated issue documenting the reason for the upgrade.
2. Review of the package changelog and migration guide.
3. Identification of breaking changes affecting Amanat code.
4. Testing in a dedicated branch or environment before merge.
5. Approval from the engineering lead or security owner.
Major version bumps must not be bundled with other changes. Each major bump is a separate PR.
### 3.4 Approval authority
| Update type | Approver |
|---|---|
| Patch (no security advisory) | Any engineer (one approval) |
| Minor (no security advisory) | Any engineer (one approval) |
| Patch or minor (with security advisory) | Engineering lead or security owner |
| Major (any) | Engineering lead or security owner |
| New dependency addition | Engineering lead or security owner |
---
## 4. Security Advisory Monitoring
### 4.1 Automated vulnerability scanning
Both repositories must be enrolled in automated vulnerability scanning. At minimum, one of the following must be active:
- **GitHub Dependabot** (if hosted on GitHub) or equivalent Gitea-native scanning.
- **npm audit** as a required CI step (exit on Critical or High).
- **Snyk** or equivalent commercial scanner (recommended for production use).
The CI pipeline must run vulnerability scanning on every push and on a daily scheduled basis.
### 4.2 Monitoring sources
Engineers must monitor the following sources for security advisories:
| Source | URL or method | Frequency |
|---|---|---|
| GitHub Security Advisories | `github.com/advisories` or Dependabot alerts | Automated |
| npm audit | `npm audit --audit-level=high` in CI | Every build |
| Snyk vulnerability DB | Snyk dashboard or CLI | Continuous |
| Dependabot / Renovate | Automated PRs for vulnerable deps | Continuous |
| Express security page | `https://expressjs.com/en/security.html` | Manual review monthly |
| Node.js security blog | `https://nodejs.org/en/blog/vulnerability` | Manual review monthly |
| Project-specific package feeds | TanStack, Axios, MUI, wagmi release notes | As released |
### 4.3 Response SLAs
When a vulnerability is identified in a dependency used by either repository, the following response timelines apply:
| Severity | Maximum time to patched version in production | Required action |
|---|---|---|
| Critical | 24 hours | Immediate patch or pin, deploy within SLA |
| High | 72 hours | Patch or pin within 48 hours, deploy within SLA |
| Medium | 1 week | Schedule in next sprint or maintenance window |
| Low | Next routine update cycle (biweekly) | Track, no expedited action required |
Severity ratings follow the advisory source (CVSS score or npm audit severity). When multiple sources disagree, the highest severity wins.
### 4.4 Vulnerability response process
When a vulnerability is discovered:
1. **Assess:** Determine severity, affected versions, and whether the Amanat codebase is actually impacted (some vulnerabilities require specific configuration or usage patterns).
2. **Patch or pin:** Update to the fixed version if available. If no fix exists, pin or remove the dependency. If pinning is not feasible, implement a compensating control (input validation, route restriction, feature flag) and document the exception.
3. **Verify:** Run the full test suite. Perform manual verification if the vulnerability affects payment, auth, or webhook flows.
4. **Deploy:** Follow the expedited deployment path if the SLA requires it. Bypass non-critical CI gates only with engineering lead approval.
All vulnerability responses must be recorded in the Known Exposure Register (Section 5).
---
## 5. Known Exposure Register
This register tracks supply-chain exposures identified during the security assessment dated 2026-05-24. It must be updated whenever a new exposure is discovered or an existing one is resolved.
| # | Package | Current Version | Vulnerability | Severity | Status | Action Required | SLA Deadline | Date Opened |
|---|---|---|---|---|---|---|---|---|
| 1 | `multer` | `^2.0.2` | Express Feb 2026 security release: high-severity Multer issues affecting versions before 2.1.0. Reference: https://expressjs.com/2026/02/27/security-releases.html | High | Open | Update to `>=2.1.0`. Verify resolved lockfile version. Run full test suite. | 2026-05-27 | 2026-05-24 |
| 2 | `axios` | In use (frontend + backend) | npm supply-chain compromise reported by Microsoft, March 2026. Reference: https://www.microsoft.com/en-us/security/blog/2026/04/01/mitigating-the-axios-npm-supply-chain-compromise/ | Critical | Open | Verify installed version is post-compromise clean build. If affected version was installed, rotate all credentials transmitted via Axios interceptors and review access logs for anomalous outbound requests. Update to latest clean version. | 2026-05-25 | 2026-05-24 |
| 3 | `@tanstack/react-query` | In use (frontend) | npm supply-chain compromise, May 2026. Reference: https://tanstack.com/blog/npm-supply-chain-compromise-postmortem | Critical | Open | Verify installed version is post-compromise clean build. If affected version was installed, review browser bundle for injected code, rotate any credentials accessible from the React query context, and audit client-side outbound network requests in production logs. Update to latest clean version. | 2026-05-25 | 2026-05-24 |
| 4 | `express` | In use (backend) | February 2026 security releases affecting Express core. Reference: https://expressjs.com/2026/02/27/security-releases.html | High | Open | Verify installed version is at or above the patched release. Run `npm audit` to confirm no residual advisory. | 2026-05-27 | 2026-05-24 |
| 5 | `node` | `node:22-alpine` (Docker) | Node.js March 2026 security releases across active release lines. Reference: https://nodejs.org/en/blog/vulnerability/march-2026-security-releases | High | Open | Update base Docker image to the latest patched Node.js 22.x release. Rebuild both Docker images. Verify runtime compatibility. | 2026-05-27 | 2026-05-24 |
**Register maintenance rules:**
- Every entry must have an owner, a status (Open, In Progress, Resolved, Accepted Risk), and a target resolution date.
- Resolved entries must not be deleted. Change status to Resolved and record the resolution details.
- Accepted Risk entries require engineering lead approval and a documented justification.
---
## 6. npm Provenance and Signature Policy
### 6.1 Provenance verification
Where npm packages offer provenance attestations (signed build metadata linking a published package to its source repository and build process), engineers must verify provenance before adopting or updating the dependency.
Verification methods:
```bash
# Check npm provenance for a package
npm audit signatures
# Verify provenance attestation (npm 10+)
npm view <package> --json | jq '.attestations'
```
### 6.2 Packages without provenance
Packages that do not offer provenance attestations are not automatically blocked, but they require additional scrutiny:
- Verify the package maintainer identity (GitHub account history, organization membership).
- Check the package download count and publication date for anomalies.
- Review recent version publish history for suspicious patterns (rapid successive publishes, new maintainers added before a release).
- Prefer packages with provenance, two-factor authentication on the maintainer account, and a history of responsible disclosure.
### 6.3 Allowlist and blocklist
The following rules apply:
| Rule | Enforcement |
|---|---|
| Packages from the `@types` scope are permitted without additional review. | Automatic |
| Packages from verified first-party scopes (`@nestjs`, `@mui`, `@tanstack`, `@sentry`, `@next`) are permitted with standard review. | Automatic |
| Any new package not previously used in the project requires engineering lead or security owner approval. | Manual gate |
| Packages known to be compromised or abandoned must be added to the project blocklist. | Immediate upon discovery |
**Blocklist mechanism:** Create a `BLOCKLIST.md` file in each repository root. CI must check that no blocklisted package appears in the dependency tree. This check can be implemented as a CI step:
```bash
# Example CI check
while IFS= read -r pkg; do
if npm ls "$pkg" 2>/dev/null | grep -q "$pkg"; then
echo "BLOCKED: $pkg found in dependency tree"
exit 1
fi
done < BLOCKLIST.md
```
---
## 7. Secrets Handling
### 7.1 Storage
Secrets must be stored exclusively in:
- Environment variables injected at runtime (`.env` files for local development, Compose `env_file` for Docker, or a secrets manager for multi-host deployments).
- A dedicated secrets manager (HashiCorp Vault, AWS SSM, or GCP Secret Manager) for production multi-host deployments.
Secrets must never be stored in:
- Source code (any file committed to git).
- Docker image layers (environment variables baked into `ENV` directives in production Dockerfiles, except for non-secret `NEXT_PUBLIC_*` values).
- Build artifacts or logs.
- Client-side JavaScript bundles (except intentionally public values prefixed `NEXT_PUBLIC_`).
See [[Environment Variables]] for the complete catalog and classification of all environment variables.
### 7.2 Rotation
| Secret type | Rotation frequency | Method |
|---|---|---|
| `JWT_SECRET` | Annually, or immediately upon suspected compromise | Generate new value (`openssl rand -hex 32`), update in all environments during maintenance window. Invalidates all active sessions. |
| `REFRESH_TOKEN_SECRET` | Annually, or immediately upon suspected compromise | Same process as `JWT_SECRET`. |
| `SHKEEPER_WEBHOOK_SECRET` | Every 6 months | Coordinate with SHKeeper dashboard. Set new secret, verify delivery, remove old. |
| `SHKEEPER_API_KEY` | Every 6 months | Generate new key in SHKeeper dashboard, update backend env. |
| `SMTP_PASS` | Every 6 months | Generate new app password, update backend env. |
| `OPENAI_API_KEY` | Every 6 months | Generate new key in OpenAI dashboard, update backend env. |
| Database passwords | Annually | Update in connection string + database user. |
| `REDIS_PASSWORD` | Annually | Update in compose entrypoint + backend `REDIS_URI`. |
| `NEXT_PUBLIC_ALCHEMY_API_KEY_*` | Every 6 months | Generate new key, rebuild frontend Docker image. |
| `NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID` | Annually | Generate in WalletConnect dashboard, rebuild frontend. |
### 7.3 Leaked secrets response
If any secret is discovered in a git commit, build log, or publicly accessible location:
1. **Immediate:** Rotate the compromised secret within 1 hour. Do not wait for investigation.
2. **Audit:** Review access logs and audit trails for the compromised secret. Determine whether the secret was used by an unauthorized party.
3. **Assess:** If the secret provided access to financial data, payment endpoints, or admin functions, escalate to the engineering lead and initiate a full incident review.
4. **Clean:** Remove the secret from git history using `git filter-branch` or BFG Repo-Cleaner if the repository is public. Force-push only with engineering lead approval.
5. **Document:** Record the leak and remediation in the incident log.
### 7.4 Frontend public env handling
`NEXT_PUBLIC_*` environment variables are embedded in the browser bundle at build time. The following rules apply:
- Never put secrets (API keys with write access, private keys, webhook secrets) in `NEXT_PUBLIC_*` variables.
- Accept that `NEXT_PUBLIC_*` values (Alchemy keys, WalletConnect ID, Sentry DSN) are visible to any browser user. These services must be configured with domain restrictions and rate limits to mitigate exposure.
- The current Dockerfile hard-codes several `NEXT_PUBLIC_*` values via `ENV` directives. This is acceptable only for non-secret public values. See [[Frontend Architecture]] for the build process and [[Infrastructure]] for Docker configuration.
---
## 8. Production Build Reproducibility
### 8.1 Deterministic builds required
Every production build must be deterministic: the same source code, lockfile, and build environment must produce bit-identical output. This enables verification that a deployed artifact matches its source.
### 8.2 Requirements for reproducible builds
| Requirement | Implementation |
|---|---|
| Frozen dependency resolution | `npm ci` with committed lockfile (see Section 2) |
| Pinned base image | Dockerfile must use a specific Node.js version tag (e.g., `node:22.x.y-alpine`), not `node:22-alpine` or `latest` |
| No floating versions in Dockerfile | Every `RUN npm install` or equivalent uses `npm ci` with the committed lockfile |
| Build-time timestamp normalization | If timestamps matter for output comparison, set `SOURCE_DATE_EPOCH` in the build environment |
| No network calls during build except package install | Build scripts must not fetch remote resources at build time (no `curl`, `wget`, or runtime API calls in Dockerfile build stages) |
### 8.3 Build artifact verification in CI
CI must produce a build artifact (Docker image) with a verifiable identity:
```bash
# Tag the image with the git commit SHA
docker build -t nickapp-backend:${GIT_COMMIT_SHA} .
# Record the image digest
docker inspect --format='{{index .RepoDigests 0}}' nickapp-backend:${GIT_COMMIT_SHA}
```
The production deployment must reference the image by digest, not just by tag. Watchtower must be reconfigured to watch a specific versioned tag (e.g., `nickapp-backend:v2.6.3`) rather than `latest`. See [[Infrastructure]] for the current Watchtower configuration and its known risks.
### 8.4 Current gaps
The current production setup has the following reproducibility gaps that must be resolved:
1. Docker base images use rolling tags (`node:22-alpine`) instead of pinned versions.
2. Watchtower auto-deploys from the `latest` tag with no staging gate.
3. No build digest verification or artifact signing.
---
## 9. Frontend vs Backend Supply-Chain Separation
### 9.1 Frontend npm risk profile
The frontend (Next.js) has a larger dependency tree due to React, MUI, TanStack, wagmi, TipTap, i18next, and their transitive dependencies. The frontend runs in the user's browser, so a compromised dependency can:
- Exfiltrate authentication tokens from `localStorage` or memory.
- Inject malicious code into the rendered page (XSS via dependency).
- Modify API requests via the Axios interceptor chain.
- Access wallet connection state (wagmi/Web3 context).
However, the frontend cannot directly execute server-side operations or access backend secrets. The blast radius of a frontend compromise is limited to the authenticated user's session and data visible to that user.
### 9.2 Backend core risk profile
The backend (Express) has a smaller dependency surface but far higher stakes. A compromised backend dependency can:
- Access database credentials and read/write any document.
- Access SHKeeper API keys and webhook secrets.
- Intercept or forge webhook payloads.
- Bypass authentication or authorization middleware.
- Access OpenAI API keys and SMTP credentials.
- Directly manipulate payment records and escrow state.
The backend must be treated as the higher-risk surface for supply-chain purposes, even though the frontend has more dependencies.
### 9.3 Policy for backend core rewrite
If the backend payment/auth/escrow core is extracted to Go, Kotlin, or Rust as recommended in [[Backend Stack Security and Refactor Assessment - 2026-05-24]], the following supply-chain separation applies:
| Component | Package ecosystem | Supply-chain policy |
|---|---|---|
| Payment/ledger/auth core (Go/Kotlin/Rust) | Go modules / Maven / Cargo | This policy applies analogously: lockfile commits, frozen install, vulnerability scanning, provenance verification |
| Marketplace/chat/notification API (remaining Node.js) | npm | This policy applies in full |
| Frontend (Next.js) | npm | This policy applies in full |
The rewritten core must not share `node_modules` with any remaining Node.js services. Cross-service communication must use authenticated internal APIs, not shared memory or shared filesystem.
### 9.4 Interim policy (both services Node-based)
While both frontend and backend remain on Node.js/npm:
1. The two repositories must maintain separate `package.json` and lockfiles. No shared `node_modules`.
2. A dependency that appears in both repositories (e.g., `axios`) must be independently reviewed and version-pinned in each.
3. Backend dependencies must be reviewed more stringently than frontend dependencies. Any dependency added to the backend must justify why it is necessary and whether a lighter alternative exists.
4. The backend must minimize its dependency count. Before adding a new backend dependency, the engineer must document: (a) what it does, (b) why existing dependencies or the Node.js standard library cannot achieve the same result, (c) the package's maintenance status and security history.
---
## 10. Incident Response for Supply-Chain Compromise
### 10.1 Compromised npm package discovered
**Detection signal:** Automated vulnerability scanner alert, security advisory publication, community report, or anomalous behavior in production.
**Immediate containment (0-1 hour):**
1. Determine which Amanat services (frontend, backend, or both) depend on the compromised package.
2. If the package is in the backend: block the affected routes at the Nginx level if the compromise affects payment, auth, or webhook processing.
3. If the package is in the frontend: assess whether the compromise can exfiltrate user tokens or modify API calls. If so, consider taking the frontend offline or deploying a known-good previous build.
4. Notify the engineering lead and all on-call engineers.
**Assessment (1-4 hours):**
1. Identify the compromised versions and the attack vector (malicious code injection, credential theft, data exfiltration).
2. Determine the clean version range (if available) from the package maintainers or security advisory.
3. Audit production logs and access records for indicators of exploitation specific to the compromise.
4. If the package had access to secrets (API keys, tokens), list all potentially exposed secrets.
**Remediation (4-24 hours):**
1. Update the package to a verified clean version, or remove it if no clean version exists.
2. Rotate all secrets that were accessible to the compromised package (see Section 7.3).
3. Deploy the fix through the standard CI pipeline with expedited review.
4. Verify the fix in staging before production deployment if time permits.
**Communication:**
1. Inform all team members of the compromise, the remediation, and any required user-facing actions.
2. If user data was exfiltrated, notify affected users and comply with applicable data breach regulations.
3. Document the incident in the Known Exposure Register (Section 5) and in the incident log.
**Post-incident review (within 1 week):**
1. Conduct a blameless post-mortem. Identify what detected the compromise (or why detection was delayed).
2. Determine whether additional controls could have prevented or detected the compromise earlier.
3. Update this policy if gaps were identified.
4. Add the compromised package to the blocklist if it remains untrusted.
### 10.2 Leaked API key or secret
**Detection signal:** Secret found in git history, build log, public repository, or unexpected API usage pattern.
**Immediate containment (0-1 hour):**
1. Rotate the leaked secret immediately. Do not wait for assessment. See Section 7.3.
2. If the secret provides database access, consider restricting network access to known IPs as an additional control while the new secret propagates.
3. Notify the engineering lead.
**Assessment (1-4 hours):**
1. Determine the scope of the leak: which environments, which time period, which services.
2. Audit access logs for the compromised secret. Look for access from unrecognized IPs, unusual request patterns, or data exfiltration.
3. Determine whether any financial data, user PII, or payment records were accessed.
**Remediation (4-24 hours):**
1. Remove the secret from git history if the repository is public or shared outside the team.
2. Verify the new secret is active and the old secret is revoked.
3. Scan all code and configuration for other instances of the same secret.
**Communication and post-incident review:** Follow the same process as Section 10.1.
### 10.3 Vulnerable dependency alert (non-compromised)
**Detection signal:** Automated scanner alert, Dependabot PR, npm audit failure.
**Process:**
1. Triage the vulnerability against the SLAs in Section 4.3.
2. Assess whether the Amanat codebase is actually affected (some vulnerabilities require specific configuration or API usage).
3. If affected: patch, test, deploy within the SLA.
4. If not affected: document the assessment in the Known Exposure Register with status Accepted Risk and the justification.
5. No post-incident review required unless the response exceeded the SLA.

## 11. CI/CD Enforcement Checklist
Every CI pipeline for both frontend and backend must enforce the following checks. A pipeline that does not pass all checks must not produce a deployable artifact.
| # | Check | Enforcement | Failure action |
|---|---|---|---|
| 1 | **Frozen lockfile install** | Pipeline uses `npm ci` (or `--frozen-lockfile` equivalent). Job fails if lockfile is out of sync with `package.json`. | Block merge |
| 2 | **npm audit / vulnerability scan passes** | `npm audit --audit-level=high` exits 0. No unresolved Critical or High vulnerabilities. | Block merge |
| 3 | **No new Critical/High vulnerabilities** | Delta check: the PR must not introduce new Critical or High vulnerabilities not present in the base branch. | Block merge |
| 4 | **Lockfile diff reviewed if changed** | If `package-lock.json` or `yarn.lock` is modified, require at least one reviewer acknowledgment in the PR. | Block merge |
| 5 | **Build is deterministic** | Build artifacts are tagged with the git commit SHA. Base images use pinned versions, not rolling tags. | Block merge |
| 6 | **No secrets in build output** | Grep the build output and Docker image layers for patterns matching private keys, API key formats (`sk-...`, `AKIA...`), and known secret prefixes. | Block merge and alert |
| 7 | **Dependency count change flagged** | If the total number of resolved dependencies changes by more than 5, flag the PR for additional review. | Require lead approval |
| 8 | **Blocklist check** | Verify no blocklisted package appears in the resolved dependency tree. | Block merge |
| 9 | **Test suite passes** | `npm run test:all` (backend) and equivalent frontend tests exit 0. | Block merge |
| 10 | **Node.js version matches production** | CI build runs on the same Node.js major.minor version as the production Docker image. | Block merge |
### Example CI configuration (Gitea Actions)
```yaml
# .gitea/workflows/security-check.yml
name: Supply-Chain Security Check
on: [push, pull_request]
jobs:
supply-chain:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Use Node.js 22.x.y (pin to production version)
uses: actions/setup-node@v4
with:
node-version: '22.x.y'
cache: 'npm'
- name: Install dependencies (frozen)
run: npm ci
# If this fails, lockfile is out of sync. Block merge.
- name: Audit for vulnerabilities
run: npm audit --audit-level=high
# Fails if any High or Critical vulnerability exists.
- name: Check blocklist
run: |
while IFS= read -r pkg; do
if npm ls "$pkg" 2>/dev/null | grep -q "$pkg"; then
echo "BLOCKED: $pkg found in dependency tree"
exit 1
fi
done < BLOCKLIST.md
- name: Scan for secrets in build output
run: |
npm run build 2>&1 | tee build.log
grep -iE '(sk-[a-zA-Z0-9]{20,}|AKIA[A-Z0-9]{16}|-----BEGIN (RSA |EC )?PRIVATE KEY-----)' build.log && exit 1 || true
- name: Flag dependency count change
run: |
CURRENT=$(npm ls --all 2>/dev/null | wc -l)
echo "Resolved dependency count: $CURRENT"
# Compare with main branch baseline if available
- name: Run tests
run: npm run test:all
```
### Deployment gate
In addition to the CI checks, the deployment process must enforce:
1. **No direct deployment from `latest` tag.** Production must deploy from a versioned tag (e.g., `v2.6.3`) or a SHA-pinned image.
2. **Staging deployment before production.** Every production deployment must first succeed in staging with passing health checks.
3. **Rollback capability.** The previous production image must be retained and redeployable within 15 minutes.

# Security Ownership and Launch Decision Criteria
**Decision document.** Answers open questions 9 and 10 from [[Backend Stack Security and Refactor Assessment - 2026-05-24]]: who owns security decisions, and what must be true before public launch.
This document is binding for the Amanat platform launch cycle. Changes require written sign-off from the roles listed in Section 1.
---
## 1. Security Ownership RACI
Roles: **PO** = Product Owner, **BL** = Backend Lead, **DI** = DevOps/Infra, **FL** = Frontend Lead, **SO** = Security Owner (if designated), **CTO** = CTO/Leadership.
R = Responsible (does the work), A = Accountable (final decision authority), C = Consulted, I = Informed.
| Decision Area | PO | BL | DI | FL | SO | CTO |
|---|---|---|---|---|---|---|
| Authentication changes (token storage, session model, passkey scope) | I | R | C | C | A | I |
| Payment/funds changes (ledger, state machine, release/refund logic) | C | R | I | I | A | I |
| Provider integrations (SHKeeper, Request Network, new providers) | C | R | C | I | A | I |
| Webhook handling (signature verification, idempotency, DLQ) | I | R | C | I | A | I |
| Rate limiting (tiers, thresholds, enforcement points) | I | R | A | I | C | I |
| Admin access (role definitions, step-up auth, audit logging) | C | R | I | C | C | A |
| Dependency updates (lockfile policy, provenance, vulnerability triage) | I | R | A | C | C | I |
| Incident response (runbook ownership, escalation, postmortem) | I | C | R | I | A | I |
| Cross-cutting security architecture (service split, stack migration) | C | R | C | C | C | A |
| External penetration testing (scope, timing, vendor selection) | I | C | C | I | R | A |
### RACI rules
- If no Security Owner is designated, accountability for rows marked **SO** defaults to **CTO**.
- **BL** is responsible for all implementation work on backend security items. **FL** is responsible for frontend-side changes (cookie migration, CSP hardening, token storage) and is consulted on rows that affect the frontend.
- **DI** owns rate limiting configuration, dependency pipeline, and infrastructure-level controls.
- A role marked **A** must approve in writing (PR review, doc sign-off, or Slack confirmation logged in the decision register) before the change ships.
- Any role marked **R** or **A** can escalate to **CTO** for final arbitration.
---
## 2. Launch Safety Gate Checklist
Each item is classified as:
- **Required** -- blocks launch. Must be verified complete before any public-facing deployment.
- **Strongly Recommended** -- should block launch. Can be accepted with a documented risk entry (risk description, owner, remediation deadline) signed by the accountable role from Section 1.
- **Deferred** -- explicitly deferred to post-launch. Must appear in Section 5 (Deferred Decisions Register).

---
## 3. Launch Priority Decision
**Decision: launch prioritizes immediate hardening of the current Node/Express stack. Backend-core redesign is deferred to post-launch.**
### Rationale
The audit findings in [[Backend Stack Security and Refactor Assessment - 2026-05-24]] and [[Platform Logical Audit - 2026-05-24]] identify the dominant risks as domain-level security failures, not framework-level weaknesses:
1. **The most dangerous issues are authorization and state-machine bugs**, not Node/Express itself. Unauthenticated financial endpoints, client-controlled socket room membership, missing dispute-escrow holds, and broken Web3 verification are independent of the backend language.
2. **A rewrite does not fix the core problems.** Moving to Go or Kotlin without first specifying the funds ledger, escrow state machine, and authorization matrix would transplant the same logic gaps into a new codebase. The audit explicitly states: "the larger issue is that the current backend mixes high-risk financial state transitions... in one Express application" -- but a rewrite that does not first solve the domain model problem is wasted effort.
3. **Hardening is faster.** The Phase 0 actions from [[Backend Stack Security and Refactor Assessment - 2026-05-24]] (disable unsafe routes, add auth checks, enable rate limiting, fix Web3 verification, fix Socket.IO auth) are discrete, testable tasks that can be completed in days, not months.
4. **The rewrite carries re-introduction risk.** The product has working business flows. A full or partial rewrite risks reintroducing escrow and payment bugs that have already been found and can be fixed in place.
### Concrete launch sequence
| Phase | Work | Timeline |
|---|---|---|
| **Phase 0: Containment** | Complete all Required items from Section 2 checklist. Disable unsafe routes, add auth/ownership enforcement, enable rate limiting, fix dispute-escrow hold, fix Web3 verification, fix Socket.IO auth, disable passkeys, rotate secrets. | Immediate |
| **Phase 1: Documentation** | Produce the 11 required documents listed in [[Backend Stack Security and Refactor Assessment - 2026-05-24]] (threat model, funds ledger spec, escrow state machine, authorization matrix, payment provider adapter spec, webhook security spec, session/auth architecture, realtime auth spec, migration plan, supply-chain policy, operational runbooks). | Parallel with Phase 0 |
| **Phase 2: Controlled launch** | Public launch proceeds once all Required checklist items pass verification. Strongly Recommended items are either completed or have documented risk acceptances. | After Phase 0 |
| **Phase 3: Payment/ledger extraction** | Build provider-neutral payment layer and immutable ledger. This is the first post-launch engineering priority. | Post-launch |
| **Phase 4: Core migration evaluation** | Decide on Go/Kotlin backend-core rewrite based on team capacity, Phase 3 outcomes, and operational experience. No migration begins until Phase 3 is stable. | Post-launch, after Phase 3 |
---
## 4. External Penetration Testing Decision
**Decision: yes, commission an external penetration test before general public launch.**
### Rationale
- Amanat is a financial escrow platform handling crypto payments. The attack surface includes webhook processing, payment state machines, Web3 transaction verification, and fund release flows. This is materially different from a typical web application.
- The audit identified critical findings (unauthenticated financial endpoints, Web3 verification bypass, dispute-escrow race condition) that an external tester would also find. An external pentest validates that the Phase 0 hardening actually closed these gaps.
- Supply-chain compromise evidence from 2026 (Axios, TanStack, Express Multer) demonstrates active threat against the npm ecosystem the platform depends on.
### Timeline and scope
| Attribute | Value |
|---|---|
| **When** | After Phase 0 hardening is complete, before Phase 2 public launch |
| **Scope** | Payment flows (SHKeeper pay-in, Web3 verification, payout/release/refund), dispute/escrow state transitions, authentication (login, token refresh, OAuth, session management), admin operations, webhook handling, Socket.IO authorization |
| **Out of scope** | Marketplace browsing/listing, blog, points/leaderboard, file upload (assessed via code review instead) |
| **Depth** | Black-box or grey-box at tester's discretion, with access to API documentation and a funded test environment |
| **Deliverable** | Report with severity ratings, reproduction steps, and remediation recommendations. Findings mapped to checklist items in Section 2. |
| **Gate** | All critical and high findings must be resolved or risk-accepted (with CTO sign-off) before launch proceeds |
### If pentest is delayed or unavailable
If the external pentest cannot be scheduled before the desired launch date, the following compensating controls must be in place:
1. Complete internal code review of all payment, auth, and webhook code paths by someone other than the original author.
2. Automated security test suite covering: unauthenticated access denial on all financial endpoints, webhook signature rejection, dispute-escrow hold enforcement, Web3 verification with wrong recipient/amount, Socket.IO unauthorized room join.
3. Documented risk acceptance signed by CTO acknowledging that external validation was not performed.

## 5. Deferred Decisions Register
Every item deferred from the launch checklist is recorded here with an owner, risk statement, and decision deadline.
| # | Decision | Risk | Owner | Decision Deadline |
|---|---|---|---|---|
| D-1 | Move access/refresh tokens from `localStorage` to `httpOnly` cookies | XSS in any frontend dependency or user-generated content leads to full session hijack. Access token at 60 min expiry limits window, but refresh token at 30 days is high value. | SO (or BL if no SO) | Within 30 days post-launch |
| D-2 | Implement immutable funds ledger for new payments | Without a ledger, payment state is mutable and auditable only through application logs. Reconciliation depends on provider records. Overpayments, partial refunds, and fee calculations have no single source of truth. | BL | Phase 3 start (within 60 days post-launch) |
| D-3 | Build provider-neutral payment abstraction layer | Current SHKeeper coupling means changing providers requires modifying core business logic. Provider-specific metadata may become canonical state by accident. | BL | Phase 3 start (within 60 days post-launch) |
| D-4 | Implement real WebAuthn/passkey authentication | Passkeys remain disabled. Users limited to password + OAuth. No phishing-resistant second factor available. | BL | Within 90 days post-launch |
| D-5 | Device and session revocation | Users cannot revoke individual sessions. Compromised refresh token remains valid until natural expiry or password change. | BL | Within 60 days post-launch |
| D-6 | Admin step-up authentication for payouts and role changes | Admin with compromised session can approve payouts or escalate roles without additional verification. | CTO | Before platform processes real funds at volume |
| D-7 | Production staging pipeline (replace Watchtower auto-deploy on `latest`) | Unvalidated images promoted to production. No health check gate, no rollback automation. | DI | Within 30 days post-launch |
| D-8 | Frontend Docker image runtime configuration injection | Same image cannot be promoted across environments without rebuild. Increases risk of configuration drift or misbuilt production images. | FL | Within 45 days post-launch |
| D-9 | Webhook dead-letter queue and structured failure alerting | Failed webhooks are silently swallowed. Reconciliation depends on manual monitoring or provider retry behavior. | BL | Within 30 days post-launch |
| D-10 | Backend-core stack migration decision (Go, Kotlin, or remain TypeScript) | Continued npm supply-chain exposure for payment core. Express flexibility allows route-level exceptions to accumulate. Decision delayed until payment layer is stable and team capacity is assessed. | CTO | After Phase 3 stability milestone (target: 120 days post-launch) |
| D-11 | Append-only audit log for payment/payout/role-change operations | Payment actions are logged via ad-hoc logger calls, not a tamper-evident audit trail. Required for dispute resolution and regulatory confidence. | BL | Within 45 days post-launch |
| D-12 | ClamAV or equivalent virus scanning on user-uploaded files | Uploaded dispute evidence and attachments served to other users without content scanning. | DI | Within 60 days post-launch |
### Governance
- The accountable owner for each deferred item is responsible for tracking progress and raising blockers.
- Items past their decision deadline without resolution escalate to CTO.
- This register is reviewed at each engineering standup or weekly review until all items are resolved or reassigned.

| Device/session revocation | user.refreshTokens[] with device metadata, revocation endpoints, max 5 sessions per user | No revocation (current), Redis-only session store | Decided |
| Admin step-up auth | Required for high-risk actions; 5-minute elevated session via re-authentication (password) | No step-up (current), hardware 2FA mandatory, passkey-only | Decided |
| Two-person approval | Required for payouts above $1,000 USD equivalent; second admin must confirm | Single-admin approval for all amounts, multi-sig wallet only | Decided |

## Section 2: Access Token Storage and Lifetime
### Decision
**We will store the access token in JavaScript memory only (a module-level variable or React context), not in localStorage, sessionStorage, IndexedDB, or any cookie.** The access token is never written to any persistent browser storage.
### Rejected alternatives
| Alternative | Rejection reason |
|---|---|
| **localStorage** (current state) | Fully accessible to any XSS payload. Threat T13: any script injection in any dependency, user-generated content field, or uploaded file exfiltrates the token. Threat T04: 7-day lifetime means a stolen token grants access for up to a week without triggering refresh rotation. |
| **httpOnly cookie** | Eliminates XSS theft but introduces CSRF risk on every API call. Requires CSRF token infrastructure for all state-changing endpoints. Adds CORS complexity because cookies are sent automatically by the browser on cross-origin requests if SameSite is not Strict. The access token must be sent on every API call, so the CSRF surface is every endpoint. |
### Rationale
In-memory storage is immune to XSS-based persistent theft. An attacker who achieves XSS can read the token during the lifetime of the page session, but the token evaporates on tab close, navigation away, or page refresh. Combined with a 15-minute expiry, the maximum exploitation window from any single XSS event is 15 minutes, not 7 days.
The access token is only needed for the duration of a browser session. The Axios interceptor holds the token in a closure variable. On page refresh, the refresh-token flow re-establishes the access token transparently.
### Token lifetime
**15 minutes** from issuance.
Rationale: Threat T04 identifies the 7-day access token lifetime as a critical risk. A stolen access token is usable for its entire lifetime without triggering refresh-token rotation. Reducing to 15 minutes limits the damage window to 15 minutes maximum. This is short enough that an attacker who exfiltrates the token via a transient XSS event (e.g., a reflected XSS that closes the page) loses access almost immediately, while long enough to avoid excessive refresh calls on a normal browsing session.
### Token format
JWT with HS256 signing (same algorithm as current). Claims:
| Claim | Value | Purpose |
|---|---|---|
| `sub` | User `_id` (ObjectId string) | Subject identification |
| `role` | `buyer`, `seller`, `admin`, `support` | Authorization enforcement |
| `iat` | Unix timestamp | Issued-at |
| `exp` | `iat + 900` (15 minutes) | Expiry enforcement |
| `jti` | UUID v4 | Token-specific identifier for audit trail and future revocation |
| `iss` | `marketplace-backend` | Issuer verification |
| `aud` | `marketplace-users` | Audience verification |
No change to the signing algorithm or secret management. The `jti` claim is new and required for audit logging and future deny-list capabilities.
### Renewal strategy
**Silent refresh with rotation.** The Axios response interceptor detects `401 TOKEN_INVALID` or `403` responses. It attempts a refresh using the httpOnly cookie (sent automatically by the browser). On success, the backend returns a new access token in the response body and sets a new refresh cookie. The interceptor updates the in-memory access token and retries the original request.
Concurrent requests during refresh: implement a refresh mutex (single inflight refresh promise). If multiple requests fail with 401 simultaneously, the first triggers the refresh; subsequent requests await the same promise and retry with the new token.
**Absolute expiry:** The refresh token has a maximum lifetime of 7 days (see Section 3). After 7 days, the user must re-authenticate. There is no sliding window that extends beyond 7 days.
### Token theft detection and response
1. **Refresh-token reuse detection** (already exists, remains in place): If a previously-used refresh token is presented, the backend invalidates all sessions for that user and forces re-authentication. The user receives an email notification: "Your session was terminated due to suspicious activity. Please sign in again."
2. **Access token theft**: Because the token is in-memory only, persistent theft requires a sustained XSS presence. The 15-minute window limits exposure. No server-side detection is possible for access-token theft alone (the token is valid until expiry). The primary defense is the short lifetime.
3. **Audit logging**: Every token issuance and refresh is logged with `jti`, `userId`, `ip`, `userAgent`, and timestamp. Abnormal patterns (e.g., refresh from a new IP geolocation far from the previous one) trigger an alert for investigation.
---
## Section 3: Refresh Token Storage, Rotation, and Revocation
### Storage location
**httpOnly, Secure, SameSite=Strict cookie** named `__Host-refresh-token`.
Cookie attributes:
| Attribute | Value | Rationale |
|---|---|---|
| `httpOnly` | `true` | Not accessible to JavaScript; immune to XSS theft |
| `secure` | `true` | Transmitted only over HTTPS |
| `sameSite` | `Strict` | Not sent on cross-origin requests; CSRF protection |
| `path` | `/api/auth/refresh-token` | Cookie sent only on the refresh endpoint, not on every API call |
| `domain` | (omitted; host-only) | Scoped to the exact origin |
| `maxAge` | `604800000` (7 days in ms) | Matches refresh token lifetime |
The `__Host-` prefix ensures the cookie cannot be set by a subdomain and requires `Secure`.
### Refresh token lifetime
**7 days** with rotation on every use.
Rationale: The current 30-day lifetime is excessive for a financial platform. Seven days provides a reasonable balance between user convenience (users are not forced to re-authenticate daily) and security (a compromised refresh token is only exploitable for 7 days maximum, and rotation reduces the window further). The deferred decision D-1 in [[Security Ownership and Launch Decision Criteria]] accepts that the migration from localStorage to httpOnly cookies must happen within 30 days post-launch. This ADR specifies the target state.
### Rotation strategy
On every refresh:
1. Backend receives the refresh token from the cookie.
2. Verifies the JWT signature and expiry.
3. Looks up the user and checks the token hash is present in `user.refreshTokens[]`.
4. Removes the old token from the array.
5. Issues a new access token (in response body) and a new refresh token (in `Set-Cookie` header).
6. Pushes the new refresh token hash to `user.refreshTokens[]`.
### Token reuse detection
If a previously-consumed refresh token is presented (i.e., the token was already rotated away and is no longer in `user.refreshTokens[]`):
1. Invalidate ALL sessions for that user: set `user.refreshTokens = []`.
2. Revoke all Redis session records for that user.
3. Send an email to the user: "A potential security issue was detected. All your sessions have been terminated. Please sign in again and change your password if you did not initiate this activity."
4. Log the event with both token hashes, the IP addresses of both the legitimate and reuse attempts, and timestamps.
This is the existing behavior documented in [[Authentication Flow]] and [[Security Architecture]] section 2.4. It remains unchanged.
### MongoDB storage schema
The `user.refreshTokens[]` array currently stores raw token strings. We will migrate to a subdocument array with metadata:
```typescript
refreshTokens: [{
tokenHash: String, // SHA-256 hash of the refresh token (not the raw token)
deviceInfo: String, // User-Agent string (truncated to 200 chars)
ipAddress: String, // IP at time of token issuance
createdAt: Date, // When the token was issued
lastUsedAt: Date, // Updated on each refresh
}]
```
The raw refresh token is never stored in MongoDB. Only its SHA-256 hash is stored. Verification compares `sha256(receivedToken) === stored.tokenHash`.
Migration: existing plain-string entries in `user.refreshTokens[]` are invalidated on the first refresh after deployment. Users with existing sessions are force-re-authenticated once.
### Revocation endpoints
**`POST /api/auth/revoke-session`**
Requires Bearer JWT. Body: `{ sessionTokenHash: string }` (the hash of the session to revoke, obtained from the session listing endpoint). The backend removes the matching entry from `user.refreshTokens[]` and deletes any Redis session keyed by tokens associated with that refresh token.
**`POST /api/auth/revoke-all-sessions`**
Requires Bearer JWT. Removes all entries from `user.refreshTokens[]` except the one used by the current request (identified by the refresh cookie). Deletes all Redis sessions for that user. The user remains logged in on the current device.
Both endpoints are audited: action, actor, target session hash, timestamp, IP, user-agent.
---
## Section 4: CSRF Strategy
### Current state
JWT is sent in the `Authorization: Bearer` header. Browsers do not attach `Authorization` headers on cross-origin requests. CSRF is currently mitigated by design (Threat T15: "Mitigated").
### Decision: no CSRF token needed for access tokens
Because the access token is stored in JavaScript memory and sent via the `Authorization` header, CSRF is not a concern for the majority of API calls. The browser will not include the `Authorization` header on a forged cross-origin request.
### CSRF protection for the refresh endpoint
The refresh token is stored in an httpOnly cookie. However, the cookie attributes provide CSRF protection:
- **`SameSite=Strict`**: The cookie is not sent on any cross-origin request, including top-level navigations from external sites. This eliminates CSRF on the refresh endpoint.
- **`Path=/api/auth/refresh-token`**: The cookie is only sent on requests to the refresh endpoint, not on any other API call.
Combined, these attributes mean an attacker cannot trigger a refresh from a cross-origin page. The `SameSite=Strict` policy is appropriate here because the refresh endpoint is never called from an external context (no OAuth callback, no payment provider redirect targets the refresh endpoint).
### If the architecture migrates access tokens to cookies later
If a future decision moves the access token to a cookie (which we explicitly reject in this ADR), CSRF tokens become mandatory. The recommended approach would be:
- Double-submit cookie pattern: set a CSRF token in a non-httpOnly cookie; the frontend reads it and includes it in a custom header (`X-CSRF-Token`). The backend verifies the header matches the cookie.
- Apply to all state-changing endpoints (POST, PUT, PATCH, DELETE).
This fallback is documented but not implemented. No action is needed unless the access token storage decision is revisited.
### Web3 wallet interactions
Web3 wallet connections (wagmi, WalletConnect) open popup windows or browser extensions for signing. These interactions do not involve the platform's cookies or tokens. The signed transaction or message is returned to the platform's JavaScript context and sent to the backend via the normal Axios interceptor with the in-memory access token. CSRF is not a concern for Web3 interactions.
---
## Section 5: Passkey/WebAuthn Decision
### Decision: Option C -- feature-flagged off in production
We will keep the current stubbed passkey implementation in the codebase, gate it behind a feature flag (`ENABLE_PASSKEYS`), and set this flag to `false` in production environments.
### Rejected alternatives
| Alternative | Rejection reason |
|---|---|
| **Option A: Remove passkeys entirely** | The frontend UI and backend routes already exist. Removing them means rebuilding the registration and sign-in UI later. The stubbed code does not pose a security risk when disabled via feature flag. |
| **Option B: Implement production WebAuthn pre-launch** | Per [[Platform Logical Audit - 2026-05-24]] Finding 2, the current implementation has three critical flaws (stubbed attestation, in-memory challenges, missing refresh-token persistence). Fixing all three, testing across platforms, and auditing the result would take 2-3 weeks of focused engineering. This is not justifiable before launch when password + OAuth authentication is sufficient. |
### Rationale
The launch gate in [[Security Ownership and Launch Decision Criteria]] Section 2.1.7 requires: "Passkey/WebAuthn disabled in production until real cryptographic implementation is complete." A feature flag is the cleanest way to comply: the code exists but cannot be reached in production. The deferred decision D-4 sets a deadline of 90 days post-launch for real WebAuthn.
### Feature flag implementation
- Backend env var: `ENABLE_PASSKEYS=false` in production, `true` in development.
- The passkey routes (`/api/auth/passkey/*`) return `404 Not Found` when the flag is `false`. The route registration itself is conditional.
- Frontend: the Passkey UI components are hidden when `NEXT_PUBLIC_ENABLE_PASSKEYS` is not `"true"`.
- Both flags are `false` by default; must be explicitly enabled.
### Target WebAuthn implementation (for D-4 resolution)
When the team implements production WebAuthn within 90 days post-launch, the following specifications apply:
**Library:** `@simplewebauthn/server` (server-side) and `@simplewebauthn/browser` (client-side).
**Relying Party configuration:**
| Parameter | Value |
|---|---|
| RP ID | Production eTLD+1 domain (e.g., `amn.gg`), NOT `localhost` |
| RP Name | `Amanat` |
| Origins | `https://amn.gg`, `https://www.amn.gg` |
| Timeout | 60 seconds |
**Challenge storage:** Redis-backed with 5-minute TTL. Key: `webauthn:challenge:{challengeHash}`. Value: `{ userId, type: 'registration' | 'authentication', createdAt }`. The in-process `Map` is removed.
**Attestation type:** `none`. Rationale: Amanat does not need to verify the authenticator manufacturer or model. Direct or indirect attestation adds complexity (managing attestation certificates, privacy concerns) without security benefit for this platform. We rely on the authenticator's signature, not its attestation.
**Credential storage (passkeys[] subdocument):**
| Field | Type | Description |
|---|---|---|
| `id` | String | Base64url-encoded credential ID |
| `publicKey` | Buffer | COSE public key (actual bytes, not a stub string) |
| `counter` | Number | Monotonic signature counter; incremented on each authentication |
| `deviceType` | String | `platform` or `cross-platform` |
| `deviceName` | String | User-provided label or auto-generated from user-agent |
| `transports` | String[] | Authenticator transports (e.g., `['internal', 'hybrid']`) |
| `registeredAt` | Date | Timestamp |
**Authentication flow integration:** Passkey login issues the same JWT pair as password login. The refresh token is persisted in `user.refreshTokens[]` using the same schema as all other authentication methods. This closes the gap identified in [[Passkey (WebAuthn) Flow]] where passkey-issued tokens were not added to the allow-list.
**Counter enforcement:** On each authentication, the received counter must be strictly greater than the stored counter. If the counter is less than or equal, the authentication is rejected, the event is logged as a potential cloned authenticator, and the user is notified.
**Cross-device authentication:** Allowed. The `transports` field in registration options includes `hybrid` to support cross-device flows (e.g., phone authenticator on desktop login).
**Migration from stubbed to real implementation:**
1. Deploy feature flag change: `ENABLE_PASSKEYS=true` in staging only.
2. Run migration: delete all entries in `user.passkeys[]` (they contain the stub `'simulated-public-key'` and are not valid credentials). Notify users that passkeys must be re-registered.
3. Deploy `@simplewebauthn/server` integration with Redis challenge store.
4. QA: test registration and authentication on Chrome (Touch ID / YubiKey), Firefox, Safari, Android, iOS.
5. Enable in production after QA sign-off.
---
## Section 6: OAuth Requirements
### Google OAuth
The current Google OAuth implementation documented in [[Google OAuth Flow]] is largely compatible with the new session model. The following adjustments apply:
**Token exchange flow:** The current implementation uses Google Identity Services (GIS) with `initTokenClient` and `requestAccessToken`. The frontend receives an ID token (Google-signed JWT). This is sent to the backend for verification. This flow is already correct -- it is equivalent to an authorization code with PKCE flow where Google handles the code exchange client-side. No change is needed.
If additional OAuth providers are added in the future (GitHub, Apple), we will use the authorization code flow with PKCE. The frontend obtains an authorization code via redirect and sends it to the backend. The backend exchanges the code for tokens server-side. This prevents the client from ever seeing the provider's access token.
**Session integration:** After Google token verification succeeds, the backend issues the same JWT access token (15-minute, in-memory) and refresh token (7-day, httpOnly cookie) as the email/password flow. There is no separate session type for OAuth users. This is the current behavior and it is correct.
**Account linking:** Account linking is implicit by email match (current behavior). If `googleUser.email` matches an existing user, the existing account is used. Risks and mitigations:
| Risk | Mitigation |
|---|---|
| Attacker creates a Google account with a victim's email before the victim signs up | Google accounts are pre-verified; the attacker must control the email address at Google. This is a standard OAuth risk. |
| Victim signs up with email/password; attacker later creates Google account with same email and gains access | The backend checks for existing users on Google sign-in and does NOT create a new account. The attacker would need the victim's Google credentials. |
| User changes Google account email to match a different user | Google tokens are verified per-request; the backend trusts the `email` from the verified ID token. If Google allows email changes (they do not for gmail.com), this could be a vector. Mitigation: consider storing `googleId` (the `sub` claim) as a separate field in the future for multi-provider identity. |
For launch, the current email-based linking is acceptable. Post-launch, we should store `providers[].providerId` (e.g., `google:123456789`) for robust multi-provider identity.
**Token storage for OAuth sessions:** Same as email/password. Access token in memory, refresh token in httpOnly cookie.
**Logout behavior for OAuth sessions:** Logout invalidates the refresh token in `user.refreshTokens[]`, clears the cookie, and deletes Redis session records. The Google session on Google's side is not terminated (we do not call Google's revoke endpoint). This is standard practice. The user must sign out of Google separately if desired.
---
## Section 7: Admin Step-Up Authentication
### Decision
High-risk admin actions require re-authentication. Upon successful re-authentication, the admin receives a short-lived elevated session. Payouts above $1,000 USD equivalent also require two-person approval.
### Definition of high-risk admin actions
| Action | Step-Up Required | Two-Person Approval | Rationale |
|---|---|---|---|
| Payout/release escrow <= $1,000 USD | Yes (password) | No | Financial action; compromised session could release funds |
| Payout/release escrow > $1,000 USD | Yes (password) | Yes | High-value financial action; dual control per Threat T18 |
| Manual wallet signing (any amount) | Yes (password) | Yes (if > $1,000) | Direct access to escrow wallet |
| Refund escrow > $500 USD | Yes (password) | No | Irreversible financial action |
| User suspension or deletion | Yes (password) | No | Account impact; potential for abuse |
| Role change (any) | Yes (password) | No | Privilege escalation vector |
| Dispute override (admin resolves against recommendation) | Yes (password) | No | Financial side-effect; high dispute value |
| API key rotation (`JWT_SECRET`, webhook secrets) | Yes (password) | No | Invalidates all sessions or compromises integrity |
| Disable rate limiting or security features | Yes (password) | No | Reduces platform security posture |
| Export user data (bulk) | Yes (password) | No | Privacy-sensitive bulk operation |
| View escrow wallet private key (if applicable) | Yes (password) | Yes | Critical asset exposure |
### Step-up mechanism
**Re-authentication with password.** The admin must enter their password to obtain an elevated session. No additional 2FA at launch (passkeys are disabled; TOTP is not yet implemented). Post-launch, when WebAuthn is production-ready (D-4), the step-up will also accept passkey authentication as a second factor.
**Elevated session:**
| Attribute | Value |
|---|---|
| Duration | 5 minutes |
| Storage | Server-side only (Redis key `stepup:{userId}` with TTL 300s) |
| Scope | Grants elevated permissions for the specific action categories listed above |
| Renewal | Re-authentication required after 5 minutes; no automatic renewal |
| Verification | Middleware `requireStepUp()` checks Redis key existence before allowing the action |
### Step-up flow
1. Admin attempts a high-risk action (e.g., `POST /api/admin/payouts/release`).
2. Middleware `requireStepUp()` checks for an active elevated session in Redis.
3. If no elevated session exists, the backend returns `403 STEP_UP_REQUIRED` with `{ challengeId: uuid }`.
4. Frontend displays a password prompt (modal dialog).
5. Frontend sends `POST /api/auth/step-up` with `{ password, challengeId }`.
6. Backend verifies the password against `user.password` using bcrypt.
7. On success, backend creates Redis key `stepup:{userId}` with TTL 300s and returns `{ elevated: true, expiresAt: timestamp }`.
8. Frontend retries the original high-risk action.
9. The action proceeds.
### Two-person approval flow
For actions requiring two-person approval:
1. Admin A completes the step-up flow above.
2. Admin A initiates the action (e.g., `POST /api/admin/payouts/release`).
3. The action is created in a `PendingApproval` state (stored in MongoDB).
4. The system notifies all other admin users via Socket.IO and email.
5. Admin B navigates to the pending approval, completes their own step-up flow, and confirms (`POST /api/admin/approvals/{id}/confirm`).
6. The action executes.
7. If Admin B rejects (`POST /api/admin/approvals/{id}/reject`), the action is cancelled.
**Fallback when second admin is unavailable:**
If no second admin has acted on a pending approval within 4 hours, the CTO (or designated fallback) receives an email and Slack notification. The CTO can approve directly. If no CTO action within 24 hours, the approval expires and must be re-initiated.
This fallback addresses the realistic scenario where Amanat has a small team with few admins. As the team grows, the 4-hour and 24-hour windows should be tightened.
### Audit logging for step-up events
All step-up and two-person approval events are logged to an append-only audit collection:
| Field | Value |
|---|---|
| `action` | `step-up.attempt`, `step-up.success`, `step-up.failed`, `approval.created`, `approval.confirmed`, `approval.rejected`, `approval.expired` |
| `actorId` | ObjectId of the admin performing the action |
| `targetAction` | The high-risk action being performed (e.g., `payout.release`) |
| `targetEntity` | ObjectId or identifier of the entity (e.g., Payment ID) |
| `ip` | Request IP |
| `userAgent` | Request user-agent |
| `timestamp` | ISO 8601 |
| `metadata` | JSON object with action-specific details (e.g., payout amount) |
This collection is not writable by the application after insert (no updates, no deletes). Access is restricted to admin read-only and system write-only.
---
## Section 8: Session Management and Device Tracking
### Session tracking
Sessions are tracked via `user.refreshTokens[]` subdocuments (see Section 3 schema). Each entry represents one authenticated device.
### Device fingerprinting
We will use lightweight, non-invasive device identification:
| Signal | Source | Storage | Notes |
|---|---|---|---|
| User-Agent | `req.headers['user-agent']` | `refreshTokens[].deviceInfo` | Truncated to 200 characters |
| IP address | `req.ip` (behind CloudFlare: `req.headers['x-forwarded-for']`) | `refreshTokens[].ipAddress` | Used for geolocation approximation |
| Platform hint | Derived from user-agent parsing | Display only | Not stored separately |
We will NOT use browser fingerprinting (Canvas, WebGL, font enumeration), device IDs, or any tracking technique that requires user consent under privacy regulations. The user-agent and IP are already sent with every HTTP request.
### Session listing
**`GET /api/auth/sessions`** (requires Bearer JWT)
Returns the list of active sessions for the current user:
```json
{
"sessions": [
{
"id": "sha256-hash-of-token",
"device": "Chrome on macOS",
"lastActive": "2026-05-24T14:30:00Z",
"ip": "203.0.113.42",
"location": "Tehran, Iran (approximate)",
"isCurrent": true
}
]
}
```
- `device` is a parsed, human-readable string derived from the user-agent (e.g., "Chrome 125 on macOS", "Safari on iPhone").
- `location` is derived from IP geolocation (city-level, approximate). We will use a local GeoIP database (MaxMind GeoLite2 or equivalent) to avoid sending user IPs to third-party services.
- `isCurrent` identifies the session making the request (matched by the refresh cookie).
### Session revocation
**`POST /api/auth/revoke-session`** (see Section 3).
Users can revoke any non-current session. Revoking the current session is equivalent to logout.
**`POST /api/auth/revoke-all-sessions`** (see Section 3).
Revokes all sessions except the current one. Useful if the user suspects compromise.
### Maximum sessions per user
**5 sessions.** When a user attempts to create a 6th session (login from a new device), the oldest session (by `createdAt`) is automatically revoked. The user is notified via email: "A new sign-in was detected on [device] from [location]. If this was not you, please change your password immediately."
Rationale: 5 sessions accommodates typical usage (desktop, laptop, phone, tablet, one more) while preventing unbounded session accumulation.
### Password change behavior
When a user changes their password:
1. All existing sessions are revoked (`user.refreshTokens = []`).
2. A new session is created for the current device.
3. All Redis session records for the user are deleted.
4. Email notification: "Your password was changed. If you did not make this change, contact support immediately."
This is the current behavior documented in [[Authentication Flow]] and it is correct.
### Account lock/suspension behavior
When an admin suspends or deletes a user account:
1. `user.status` is set to `suspended` or `deleted`.
2. `user.refreshTokens` is set to `[]`.
3. All Redis session records for the user are deleted.
4. Any in-flight requests with tokens for that user return `403 ACCOUNT_SUSPENDED` or `403 ACCOUNT_DELETED` on the next request (the `authMiddleware` already checks `user.status`).
---
## Section 9: Migration Plan
### Current state
| Component | Current | Target | Change Level |
|---|---|---|---|
| Access token storage | localStorage | In-memory variable | Frontend only |
| Access token lifetime | 7 days | 15 minutes | Backend config |
| Refresh token storage | localStorage | httpOnly cookie (backend set) | Full stack |
| Refresh token lifetime | 30 days | 7 days | Backend config |
| Refresh token schema | `String[]` | Subdocument array with metadata | Backend + DB migration |
| CSRF protection | Not needed (header-based) | Not needed (header-based + SameSite cookie) | None |
| Passkey status | Stubbed, accessible | Feature-flagged off in production | Backend + Frontend |
| Session revocation | Not implemented | Endpoints + device listing | Backend + Frontend |
| Admin step-up | Not implemented | Password re-auth + elevated session | Backend + Frontend |
| Two-person approval | Not implemented | Pending approval workflow | Backend + Frontend |
### Migration steps (in order)
**Step 1: Backend -- reduce access token lifetime to 15 minutes**
- Change `JWT_EXPIRES_IN` default from `7d` to `15m`.
- Deploy. Existing 7-day tokens remain valid until they expire naturally (no force-invalidations).
- Risk: users with long-lived sessions will notice more frequent refreshes. This is expected and acceptable.
**Step 2: Backend -- refresh token lifetime to 7 days**
- Change `REFRESH_TOKEN_EXPIRES_IN` default from `30d` to `7d`.
- Deploy. Existing 30-day refresh tokens remain valid until they expire or are rotated.
**Step 3: Backend -- add refresh token metadata to refreshTokens[]**
- Deploy new schema: `user.refreshTokens` becomes a subdocument array with `tokenHash`, `deviceInfo`, `ipAddress`, `createdAt`, `lastUsedAt`.
- Migration script: convert existing `String[]` entries to `{ tokenHash: sha256(entry), deviceInfo: 'Unknown (pre-migration)', ipAddress: 'unknown', createdAt: Date.now(), lastUsedAt: Date.now() }`.
- Login and refresh endpoints updated to write new schema.
- Deploy. Old-format entries continue to work during migration.
**Step 4: Backend -- set refresh token as httpOnly cookie**
- On login, refresh, and OAuth sign-in: set `Set-Cookie` header with the refresh token in an httpOnly cookie. Also return the refresh token in the response body for backward compatibility.
- Add `POST /api/auth/refresh-token-cookie` endpoint that accepts the refresh token from the body and sets it as a cookie (migration helper for existing sessions).
- Deploy. Frontend still works with body-based refresh tokens.
**Step 5: Frontend -- move access token to in-memory storage**
- Replace `localStorage.getItem('accessToken')` and `localStorage.setItem('accessToken', ...)` with an in-memory store (module-level variable or React context).
- On app load: check for refresh cookie. If present, call refresh endpoint to obtain a new access token. If no cookie, redirect to login.
- Remove `localStorage` writes for both tokens. On logout, clear the in-memory token and the cookie (by calling the logout endpoint which sets an expired cookie).
- Deploy frontend.
**Step 6: Frontend -- send refresh via cookie instead of body**
- Modify the Axios interceptor to NOT send `refreshToken` in the body of `POST /api/auth/refresh-token`. The refresh token is sent automatically via the cookie.
- Backend: accept refresh token from either cookie or body (backward compatible). Deprecate body-based refresh with a log warning.
- Deploy both.
**Step 7: Backend -- add session management endpoints**
- `GET /api/auth/sessions` -- list active sessions.
- `POST /api/auth/revoke-session` -- revoke a specific session.
- `POST /api/auth/revoke-all-sessions` -- revoke all other sessions.
- Deploy. No frontend change yet (endpoints are available but unused).
**Step 8: Frontend -- add session management UI**
- Account settings page: "Active Sessions" section listing devices, locations, and last active times.
- "Revoke" button per session. "Revoke all other sessions" button.
- Deploy frontend.
**Step 9: Backend -- feature flag for passkeys**
- Add `ENABLE_PASSKEYS` env var (default `false`).
- Gate all `/api/auth/passkey/*` routes behind the flag.
- Return `404` when disabled.
- Deploy.
**Step 10: Frontend -- feature flag for passkey UI**
- Add `NEXT_PUBLIC_ENABLE_PASSKEYS` env var (default `false`).
- Hide passkey UI components when disabled.
- Deploy frontend.
**Step 11: Backend -- admin step-up authentication**
- Add `POST /api/auth/step-up` endpoint.
- Add `requireStepUp()` middleware.
- Apply middleware to high-risk admin routes.
- Add Redis-based elevated session store.
- Deploy.
**Step 12: Frontend -- admin step-up UI**
- Password prompt modal for step-up challenges.
- Intercept `403 STEP_UP_REQUIRED` responses and show modal.
- Retry original request after successful step-up.
- Deploy frontend.
**Step 13: Backend -- two-person approval**
- Add `PendingApproval` collection.
- Add approval workflow endpoints.
- Apply to payout/release actions above $1,000.
- Add notification logic for other admins.
- Deploy.
**Step 14: Frontend -- two-person approval UI**
- Pending approvals list in admin dashboard.
- Confirm/reject actions with step-up.
- Deploy frontend.
**Step 15: Backend -- remove body-based refresh token acceptance**
- After all frontends are migrated (Step 6 + reasonable buffer of 2 weeks), stop accepting refresh tokens from the request body.
- Accept refresh tokens only from the cookie.
- Deploy.
### Feature flags
| Flag | Default | Environments | Purpose |
|---|---|---|---|
| `ENABLE_PASSKEYS` | `false` | All | Controls passkey route registration |
| `NEXT_PUBLIC_ENABLE_PASSKEYS` | `false` | All | Controls passkey UI visibility |
| `COOKIE_REFRESH_MIGRATION` | `false` | All | Enables cookie-based refresh token issuance |
| `REQUIRE_STEP_UP` | `false` | Staging, Production | Enables step-up auth for admin actions |
### Rollback plan
If any migration step causes issues:
1. **Steps 1-2 (token lifetimes):** Revert `JWT_EXPIRES_IN` and `REFRESH_TOKEN_EXPIRES_IN` to previous values. Redeploy. No data migration to undo.
2. **Steps 3-4 (refresh token schema + cookies):** Backend continues to accept body-based refresh tokens. Frontend can revert to `localStorage` storage. The httpOnly cookie is additive; removing it does not break existing sessions.
3. **Step 5 (in-memory access token):** Frontend can revert to `localStorage`. The backend does not care where the access token comes from.
4. **Steps 7-8 (session management):** These are additive endpoints and UI. Rolling back means removing the UI and endpoints. No data is affected.
5. **Steps 9-10 (passkey feature flag):** Set flags to `true` to restore passkey access (though passkeys remain stubbed and insecure). Rolling back is simply changing env vars.
6. **Steps 11-14 (step-up and two-person approval):** Remove `requireStepUp()` middleware. Admin actions proceed without step-up. This is a security regression but not a functional outage.
### Timeline estimate
| Phase | Steps | Duration | Dependencies |
|---|---|---|---|
| Token hardening | 1-2 | 1 day | None |
| Cookie migration | 3-6 | 3-5 days | Frontend + backend coordination |
| Session management | 7-8 | 2-3 days | Cookie migration complete |
| Passkey feature flag | 9-10 | 1 day | None |
| Admin step-up | 11-12 | 3-4 days | None |
| Two-person approval | 13-14 | 3-5 days | Admin step-up complete |
| Cleanup (step 15) | 15 | 1 day (after 2-week buffer) | All frontends migrated |
| **Total** | | **14-21 days** | |

## Section 10: Threat Mitigation Traceability
| Decision | Threats Addressed | Risk Reduction |
|---|---|---|
| Access token in memory (not localStorage) | T13 (XSS token theft) | XSS cannot persistently steal the token; it is lost on page unload |
| Access token lifetime reduced to 15 min | T04 (stolen token reuse) | Stealable token valid for 15 min instead of 7 days (672x reduction in exposure window) |
| Refresh token in httpOnly cookie | T04, T13 | XSS cannot read the refresh token; it is not accessible to JavaScript |
| Refresh token lifetime reduced to 7 days | T04 | Maximum exploitation window from a compromised refresh token is 7 days instead of 30 days |
| Refresh token rotation with reuse detection | T04 | Reuse of a rotated token triggers full session invalidation; attacker and legitimate user are forced to re-authenticate |
| SameSite=Strict on refresh cookie | T15 (CSRF) | Cookie not sent on cross-origin requests; CSRF on refresh endpoint is eliminated |
| Refresh cookie scoped to `/api/auth/refresh-token` path | T15 | Cookie sent only on the refresh endpoint; not on any state-changing endpoint |
| Passkey feature flag disabled in production | T10 (passkey bypass) | Stubbed passkey implementation is unreachable in production; cannot be exploited |
| Session revocation endpoints | T04 | Users can terminate compromised sessions immediately; admins can revoke sessions for suspended users |
| Max 5 sessions per user | T04 | Limits blast radius of session accumulation; oldest sessions auto-revoked |
| Admin step-up authentication | T09 (admin privilege escalation), T18 (insider fund manipulation) | Compromised admin session cannot perform high-risk actions without re-authenticating; elevated session lasts only 5 minutes |
| Two-person approval for large payouts | T05 (double payout), T18 | No single admin can release high-value escrow; second admin must independently verify and approve |
| Audit logging for step-up and approval events | T09, T18 | All elevated-access events are recorded in tamper-evident audit trail |
| Password change revokes all sessions | T04 | If user detects compromise, password change immediately terminates all attacker sessions |
| Account suspension revokes all sessions | T09 | Compromised admin accounts are immediately locked out when suspended |
| Device/session listing | T04 | Users can detect unfamiliar sessions and revoke them; early detection of compromise |
| Email notification on new device login | T04 | User is alerted to unauthorized access within minutes |
| Verification code removal from production logs | T22 (verification code leakage) | Codes are no longer loggable in production; only non-production environments may log them for debugging |
| Access token `jti` claim | T04 | Each token has a unique identifier; enables future deny-listing of individual tokens |
| OAuth token storage same as email/password | T04, T13 | OAuth sessions receive the same protections (in-memory access, httpOnly refresh) |
### Coverage analysis
| Threat | Mitigated by this ADR? | Residual risk |
|---|---|---|
| T04 (stolen token reuse) | Yes -- 15-min access token, httpOnly refresh cookie, rotation, session revocation | Physical access to an unlocked device with an active session; keylogger capturing password during step-up |
| T10 (passkey bypass) | Yes -- feature flag disabled in production | None (passkeys are unreachable) |
| T13 (XSS token theft) | Yes -- in-memory access token, httpOnly refresh cookie | Transient XSS can read in-memory token for up to 15 minutes; XSS cannot access refresh token |
| T15 (CSRF) | Yes -- access token in Authorization header (unchanged), SameSite=Strict on refresh cookie | None |
| T22 (verification code leakage) | Partially -- ADR documents the requirement; implementation is a separate task | Codes still logged until code change is deployed |

## 1. System Description
### 1.1 What is Amanat
Amanat is a financial escrow marketplace where buyers and sellers transact in cryptocurrency (USDT, USDC on BSC and Ethereum). The platform holds buyer funds in a custodial escrow wallet during order fulfillment and releases or refunds them based on delivery outcome or dispute resolution. It is not a simple CRUD marketplace; it is a financial platform with custody obligations.
### 1.2 Technology stack
| Layer | Technology |
|---|---|
| Frontend | Next.js (React), MUI, wagmi/Web3, Socket.IO client |
| Backend | Express 5, TypeScript, Mongoose, Socket.IO |
| Database | MongoDB (primary), Redis (caching, lockout, rate-limit) |
| Payments - hosted | SHKeeper self-hosted gateway at `pay.amn.gg` |
| Payments - direct | Web3/wagmi wallet transfer to custodial escrow address |
| Blockchain | BSC mainnet (chain ID 56), Ethereum; USDT/USDC BEP-20/ERC-20 |
| Realtime | Socket.IO 4.8 with client-driven room joins |
| Email | Nodemailer via SMTP |
| AI | OpenAI API for content generation, analysis, translation |
| Infrastructure | Docker Compose on single host, Nginx reverse proxy, CloudFlare upstream |
| Deployment | Watchtower auto-pull on `latest` tag (no staging gate) |
### 1.3 Key data flows
**Pay-in to escrow (SHKeeper path):**
Buyer selects offer -> Backend creates Payment intent -> SHKeeper allocates deposit address -> Buyer sends crypto -> SHKeeper webhook confirms -> Backend sets `escrowState=funded` -> Cascade: offer accepted, request status advanced, chat created.
**Pay-in to escrow (Web3 path):**
Buyer connects wallet -> Backend records pending Payment -> Buyer signs on-chain transfer to escrow wallet -> Backend verifies `eth_getTransactionReceipt` -> Sets `escrowState=funded` -> Same cascade.
**Escrow hold:**
Funds sit at custodial BSC wallet. `Payment.escrowState=funded`. No on-chain action occurs. Admin dashboard shows all funded escrows.
**Release to seller:**
Buyer confirms delivery (or auto-release timer) -> Admin initiates payout via SHKeeper Payouts API or manual wallet signing -> On-chain transfer to seller wallet -> `escrowState=released`.
**Refund to buyer:**
Dispute resolved with refund action, or pre-shipment cancellation -> Admin builds refund tx payload -> Admin signs and broadcasts -> `escrowState=refunded`.
**Dispute flow:**
Buyer or seller opens dispute -> Three-way chat created (buyer, seller, admin) -> Admin assigned -> Evidence gathered -> Admin resolves (release/refund/partial/reject) -> Financial side-effect dispatched manually.
**Webhook flow (SHKeeper):**
SHKeeper POSTs to `/api/payment/shkeeper/webhook` with HMAC-SHA256 signature -> Backend verifies raw-body signature -> Deduplicates by `(providerPaymentId, status)` tuple -> PaymentCoordinator serializes state update -> Cascade to offer/request/chat/notification.

## 3. Actors
| Actor | Access Level | Motivation | Risk Profile |
|---|---|---|---|
| **Buyer** | Authenticated (`role: buyer`). Can create requests, pay, confirm delivery, open disputes, rate. | Complete purchase, get refund if unsatisfied, dispute bad service. May attempt to bypass payment or confirm without delivery. | Medium. Motivated to fraud payment or delivery confirmation. |
| **Seller** | Authenticated (`role: seller`). Can create offers, templates, shop settings, receive payouts. | Receive payment for goods/services. May attempt to mark unshipped items as delivered or inflate prices post-acceptance. | Medium. Motivated to receive funds without delivery. |
| **Admin** | Authenticated (`role: admin`). Full access to user management, dispute resolution, manual payouts, payment dashboard. | Platform operations. Single point of trust for fund release. | High. If compromised, can release all escrowed funds. |
| **Support staff** | Authenticated (`role: support`). Read-only access, password resets, escalation. | Customer support operations. | Low-Medium. Limited destructive capability but can read sensitive data. |
| **Unauthenticated attacker** | No auth. Can reach public endpoints, Socket.IO handshake (rejected without JWT), webhook route (requires HMAC). | Financial gain, data theft, service disruption, cost abuse. | High. Broad attack surface including unauthenticated endpoints. |
| **Compromised user** | Valid JWT for a buyer/seller account. | Attacker uses stolen session to redirect payouts, open fraudulent disputes, exfiltrate data. | High. Hard to distinguish from legitimate activity. |
| **Compromised admin** | Valid JWT with admin role. | Full platform compromise: release escrows, manipulate payments, exfiltrate all user data. | Critical. Single compromised admin session can drain the escrow wallet. |
| **Malicious payment provider / webhook sender** | Can POST to webhook endpoint. | Inject false payment confirmations to trigger release. | High. If webhook verification is flawed, funds are at risk. |
| **Malicious blockchain actor** | Can submit any tx hash for verification. | Submit a tx hash for an unrelated successful transfer (wrong recipient/amount) and get it accepted as payment. | High. Current Web3 verification is incomplete. |
| **Insider threat** | Legitimate access to infrastructure, code, or admin tools. | Fund manipulation, data exfiltration, backdoor insertion. | Critical. Trust boundary cannot be fully technical. |
| **Supply-chain attacker** | Can compromise npm packages used by the project. | Remote code execution, credential theft, payment flow manipulation. | High. Real 2026 precedent with Axios, TanStack compromises. |

### 4.2 Boundary descriptions
| Boundary | Crossing Protocol | Trust Assumption | Current Gap |
|---|---|---|---|
| Browser <-> Backend API | HTTPS, JWT in `Authorization` header, CORS allow-list | Browser is untrusted; JWT proves identity | Tokens stored in `localStorage` (XSS-exposed); 7-day access token lifetime |
| Browser <-> Socket.IO | WSS, JWT in handshake `auth.token` | Socket is untrusted until JWT verified | Room joins are client-driven with `userId` argument; server-side verification may be incomplete (`socketService.ts` citation needed) |
| Backend <-> MongoDB | Mongoose on `localhost:27017` (no TLS in dev) | Database is trusted; network is trusted (single host) | No TLS, no auth on MongoDB connection in default config |

## 5. Threat Catalog
### T01 -- Fake Payment Proof Submission
| Field | Value |
|---|---|
| **STRIDE** | Spoofing |
| **Affected assets** | Payment records, escrow funds |
| **Actors** | Buyer, malicious blockchain actor |
| **Description** | In the Web3 payment path, the backend accepts a `transactionHash` and verifies it via `eth_getTransactionReceipt`. The current `BSCTransactionVerifier` checks only `receipt.status === '0x1'` (transaction succeeded). It does not decode the ERC-20 `Transfer` event to verify that `to` matches `ESCROW_WALLET_ADDRESS` or that `value` matches the expected payment amount. A buyer can submit the hash of any successful USDT transfer (e.g., a 0.01 USDT transfer to their own wallet) and the system marks the payment as `completed` with `escrowState=funded`. |
| **Current state** | Vulnerable |
| **Required mitigation** | Decode `Transfer(address,address,uint256)` event from `receipt.logs`. Assert `to == ESCROW_WALLET_ADDRESS` and `value >= expectedAmount` (with decimal adjustment). Reject if mismatch. Reference: [[Payment Flow - DePay & Web3]], `decentralizedPaymentService.ts`. |
### T02 -- Webhook Replay Attack
| Field | Value |
|---|---|
| **STRIDE** | Spoofing / Tampering |
| **Affected assets** | Payment records, escrow funds |
| **Actors** | Malicious webhook sender, man-in-the-middle |
| **Description** | SHKeeper webhooks are verified using HMAC-SHA256 of the raw body against `SHKEEPER_WEBHOOK_SECRET`. However: (a) in development mode, signature verification is bypassed entirely; (b) the handler deduplicates by comparing `(metadata.shkeeperStatus, balance_fiat, paid)` within a 10-second window, but a replay outside that window with identical payload could be processed again; (c) there is no nonce, timestamp, or delivery-ID check from SHKeeper. An attacker who captures a valid webhook payload can replay it to mark a different payment as paid. |
| **Current state** | Partially mitigated |
| **Required mitigation** | Implement webhook delivery-ID tracking (store `delivery_id` or `(external_id, status)` as idempotency key). Reject webhooks older than a configurable window. Never bypass signature verification in any non-local environment. Add dead-letter storage for failed webhooks. Reference: [[Payment Flow - SHKeeper]], `shkeeperWebhook.ts`. |
### T03 -- Arbitrary Socket.IO Room Join
| Field | Value |
|---|---|
| **STRIDE** | Information disclosure / Elevation of privilege |
| **Affected assets** | Realtime event streams, private notifications, chat messages |
| **Actors** | Compromised user, unauthenticated attacker (with stolen JWT) |
| **Description** | Socket.IO room joins are client-driven. The client emits events like `join-user-room {userId}`, `join-seller-room {sellerId}`, `join-chat-room {chatId}`. The documentation explicitly warns that `userId` arguments "are NOT trusted blindly" but notes the authorization check in `socketService.ts` "needs verification." If the server does not verify `socket.data.user.id === userId` before joining, any authenticated user can subscribe to any other user's private notifications (`user-{otherUserId}`), seller events (`seller-{otherSellerId}`), or chat rooms (`chat-{otherChatId}`). |
| **Current state** | Vulnerable (verification status uncertain) |
| **Required mitigation** | Remove client-driven `join-*-room` events. After JWT handshake, the server should automatically join the socket to `user-{decoded.id}`. For role rooms (`seller-*`, `buyer-*`), derive membership from `decoded.role`. For chat rooms, verify that `decoded.id` is in `chat.participants`. Reference: [[Real-time Layer]], `socketService.ts`. |
### T04 -- Stolen Token Reuse
| Field | Value |
|---|---|
| **STRIDE** | Spoofing / Elevation of privilege |
| **Affected assets** | User sessions, admin sessions, all user-owned data |
| **Actors** | Compromised user, compromised admin |
| **Description** | Access tokens are JWTs stored in `localStorage` with a 7-day expiry. If an XSS vulnerability exists (or a compromised npm dependency injects a script), the attacker exfiltrates both `accessToken` and `refreshToken` from `localStorage`. The refresh token rotation mechanism detects reuse (if the same refresh token is presented twice, all sessions are invalidated), but the attacker can use the access token for up to 7 days without triggering rotation. For admin accounts, a stolen token gives full platform control including manual payout signing. |
| **Current state** | Partially mitigated (rotation exists, but storage and lifetime are weak) |
| **Required mitigation** | (1) Move refresh tokens to `httpOnly` secure cookies. (2) Reduce access token lifetime to 15-60 minutes. (3) Keep only the access token in memory (not localStorage). (4) Implement CSRF protection if cookies are used. Reference: [[Security Architecture]] section 11, [[Authentication Flow]]. |
### T05 -- Double Payout / Double Release
| Field | Value |
|---|---|
| **STRIDE** | Tampering / Repudiation |
| **Affected assets** | Payment records, escrow funds |
| **Actors** | Compromised admin, race condition (concurrent requests) |
| **Description** | The payout flow (`shkeeperPayoutService.createPayoutTask`) has idempotency: it checks for an existing outgoing Payment with the same `(purchaseRequestId, sellerOfferId, sellerId, provider, direction:'out')` in `pending/processing/completed` status. However: (a) the manual admin payout path (`admin-wallet-payout.tsx`) signs on-chain directly and then calls `confirmAdminTx`, with no corresponding idempotency guard; (b) the `PaymentCoordinator` serializes updates for a single payment, but two concurrent payout requests for different payments against the same escrow balance are not guarded; (c) `escrowState` is a mutable field, not derived from an immutable ledger. An admin (or attacker with admin credentials) could trigger two payouts for the same underlying funds. |
| **Current state** | Partially mitigated |
| **Required mitigation** | (1) Introduce an immutable funds ledger (`FundsAccount`, `LedgerEntry`) so that releasable balance is derived, not stored. (2) Add a distributed lock (Redis) around payout creation for a given escrow. (3) Require admin step-up authentication or two-person approval for payouts above a threshold. Reference: [[Escrow Flow]], [[Payout Flow]], [[Backend Stack Security and Refactor Assessment - 2026-05-24]] Phase 2. |
### T06 -- Dispute Bypass (Release During Active Dispute)
| Field | Value |
|---|---|
| **STRIDE** | Tampering |
| **Affected assets** | Escrow funds, dispute records |
| **Actors** | Compromised admin, buyer (if auto-release fires) |
| **Description** | Opening a dispute does not change `Payment.escrowState` away from `funded`. The Dispute Flow explicitly documents this: "Today, opening a dispute does not flip `Payment.escrowState` away from `funded`. An admin could theoretically still release the escrow before resolving the dispute." The Dispute API claims dispute creation "pauses any in-flight payout," but the implementation does not enforce this in the `PaymentCoordinator` or `PayoutService`. A release or refund can proceed while a dispute is active. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Add a `disputed` escrow state or a `disputeHold` flag on Payment that blocks all release/refund operations. (2) Enforce this in `PaymentCoordinator` and `shkeeperPayoutService` as a precondition. (3) Auto-set this flag in `DisputeService.createDispute`. (4) Clear only when dispute is resolved. Reference: [[Dispute Flow]], [[Escrow Flow]], [[Platform Logical Audit - 2026-05-24]] Finding 1. |
### T07 -- Email / Registration Abuse
| Field | Value |
|---|---|
| **STRIDE** | Denial of service / Spoofing |
| **Affected assets** | Email service, user accounts |
| **Actors** | Unauthenticated attacker |
| **Description** | The registration endpoint (`POST /api/auth/register`) triggers an email dispatch for every request. The resend endpoint (`POST /api/auth/resend-verification`) does the same. Rate limiting is disabled globally. An attacker can submit thousands of registration requests with random or victim email addresses, causing: (a) SMTP cost explosion; (b) email service reputation damage (spam complaints); (c) `TempVerification` collection bloat in MongoDB. Additionally, the 6-digit verification code is logged to stdout in all environments, leaking it to anyone with log access. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Enable rate limiting on `/api/auth/register` and `/api/auth/resend-verification` (e.g., 5 requests per 15 minutes per IP, 3 per email). (2) Remove `console.log` of verification codes in production. (3) Add CAPTCHA or proof-of-work for registration. (4) Add TTL index on `TempVerification` collection for auto-cleanup. Reference: [[Registration Flow]], [[Security Architecture]] section 9. |
### T08 -- AI Cost Abuse (Unauthenticated / Over-Budget Usage)
| Field | Value |
|---|---|
| **STRIDE** | Denial of service (financial) |
| **Affected assets** | AI usage budgets, `OPENAI_API_KEY` cost |
| **Actors** | Unauthenticated attacker, compromised user |
| **Description** | All AI endpoints (`/api/ai/generate`, `/api/ai/analyze`, `/api/ai/translate`, `/api/ai/assist`) currently have no authentication or caller identity verification, as documented in the Platform Logical Audit. Any client can call these endpoints and incur OpenAI API costs. Even if authentication is added, there is no per-user budget tracking, daily limit, or cost attribution. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Require Bearer JWT on all AI routes. (2) Implement per-user daily/monthly token budgets stored in MongoDB or Redis. (3) Rate-limit AI endpoints separately (e.g., 20 requests per hour per user). (4) Alert on abnormal cost spikes. Reference: [[Platform Logical Audit - 2026-05-24]] Finding 3. |
### T09 -- Admin Privilege Escalation
| Field | Value |
|---|---|
| **STRIDE** | Elevation of privilege |
| **Affected assets** | All platform assets |
| **Actors** | Compromised user, insider |
| **Description** | Admin role is stored as a string field `role: 'admin'` on the User document. If any route or service fails to enforce `roleGuard('admin')`, an ordinary user can access admin-only endpoints. The audit identifies that "admin-sensitive routes need explicit role enforcement, not just authentication." The admin bootstrap seed creates an admin with known credentials; if these are not rotated before launch, anyone who knows the seed email/password gains admin access. Additionally, there is no step-up authentication for high-risk admin operations (payouts, role changes, user deletion). |
| **Current state** | Partially mitigated (roleGuard exists but may not be applied consistently) |
| **Required mitigation** | (1) Audit every admin route for `roleGuard('admin')` enforcement. (2) Rotate all seed admin credentials before launch. (3) Implement step-up authentication (re-authentication or 2FA) for payouts, role changes, and user suspension. (4) Add audit logging for all admin actions. Reference: [[Security Architecture]] section 3, [[Backend Architecture]] section 4. |
### T10 -- Passkey / WebAuthn Bypass
| Field | Value |
|---|---|
| **STRIDE** | Spoofing |
| **Affected assets** | User credentials, sessions |
| **Actors** | Unauthenticated attacker, compromised user |
| **Description** | The passkey implementation has three critical flaws: (a) The `publicKey` field is stored as the literal string `'simulated-public-key'` rather than the actual COSE public key from the attestation object. A malicious client can register any credential ID under any user account. (b) Challenges are stored in an in-process `Map`, not Redis, breaking in multi-instance deployments. (c) Passkey-issued refresh tokens are not appended to `user.refreshTokens[]`, so the standard refresh endpoint rejects them, and the token reuse detection mechanism does not apply. |
| **Current state** | Vulnerable (passkeys are stubbed and non-functional for security) |
| **Required mitigation** | (1) Replace stub attestation with `@simplewebauthn/server`. Store real COSE public keys. (2) Move challenge storage to Redis with TTL. (3) Persist passkey-issued refresh tokens in `user.refreshTokens[]`. (4) Enforce monotonic counter to detect cloned authenticators. (5) Consider disabling passkey feature entirely until production-ready. Reference: [[Passkey (WebAuthn) Flow]], [[Platform Logical Audit - 2026-05-24]] Finding 2. |
### T11 -- Web3 Payment with Wrong Recipient / Token / Amount
| Field | Value |
|---|---|
| **STRIDE** | Spoofing |
| **Affected assets** | Payment records, escrow funds |
| **Actors** | Buyer, malicious blockchain actor |
| **Description** | Closely related to T01 but distinct in scope. The `POST /api/payment/decentralized/save` and `POST /api/payment/decentralized/update` endpoints are unauthenticated (per the audit findings). This means any client can create or modify decentralized payment records in the database without any on-chain verification. Combined with the incomplete `BSCTransactionVerifier`, an attacker can: (a) save a fake payment with arbitrary status; (b) update confirmations to make it appear verified; (c) trigger the cascade that accepts an offer and advances the purchase request. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Add authentication to all `/api/payment/decentralized/*` endpoints. (2) Add ownership verification (the authenticated user must be the buyer of the referenced purchase request). (3) Harden `BSCTransactionVerifier` per T01. (4) Remove test endpoints from production builds. Reference: [[Platform Logical Audit - 2026-05-24]] Finding 3, [[Payment Flow - DePay & Web3]]. |
### T12 -- Rate Limit Bypass
| Field | Value |
|---|---|
| **STRIDE** | Denial of service |
| **Affected assets** | All endpoints, email service, AI budget, database |
| **Actors** | Unauthenticated attacker |
| **Description** | `express-rate-limit` is explicitly disabled in the Express application (`app.ts:227`). The documentation describes recommended limits but they are not active. Without rate limiting, every endpoint is exposed to abuse: brute-force login attempts, registration email spam, AI cost explosion, payment endpoint flooding, and chat/message spam. Redis-based counters are wired but not enforced. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Enable rate limiting globally with tiered limits: auth paths (5-10 req/5 min/IP), payment paths (20 req/15 min/user), AI paths (20 req/hr/user), chat/messaging (30 req/min/user), file upload (10 req/hr/user), global default (100 req/15 min/IP). (2) Store counters in Redis. (3) Return `429 Too Many Requests` with `Retry-After` header. Reference: [[Security Architecture]] section 9, [[Backend Architecture]] section 3. |
### T13 -- XSS Leading to Token Theft
| Field | Value |
|---|---|
| **STRIDE** | Tampering / Information disclosure |
| **Affected assets** | User sessions, admin sessions |
| **Actors** | Unauthenticated attacker (via stored XSS), compromised user (via reflected XSS) |
| **Description** | Access tokens and refresh tokens are stored in `localStorage`. Any XSS vulnerability -- whether from a stored payload in chat messages, product descriptions, blog posts, dispute evidence, or user profile fields -- allows an attacker to read both tokens via `localStorage.getItem()`. Helmet CSP is in place but configured permissively for Web3 popup compatibility (`COEP: unsafe-none`, `COOP: same-origin-allow-popups`). React auto-escapes output, but `dangerouslySetInnerHTML` may be used in blog or description rendering. File uploads (dispute evidence, chat attachments) are served from `/uploads` without authentication, and a malicious SVG or HTML file could execute scripts in the context of the application. |
| **Current state** | Partially mitigated (CSP, React escaping, MIME validation exist) |
| **Required mitigation** | (1) Move tokens out of `localStorage` per T04. (2) Tighten CSP; evaluate whether `unsafe-none` COEP is necessary. (3) Audit all uses of `dangerouslySetInnerHTML`. (4) Serve uploads with `Content-Disposition: attachment` and `X-Content-Type-Options: nosniff`. (5) Add virus scanning (ClamAV) for uploaded files. Reference: [[Security Architecture]] section 11, section 7. |
### T14 -- npm Supply-Chain Compromise
| Field | Value |
|---|---|
| **STRIDE** | Tampering / Elevation of privilege / Information disclosure |
| **Affected assets** | All backend and frontend code, secrets, user data |
| **Actors** | Supply-chain attacker |
| **Description** | Both frontend and backend depend heavily on npm packages. The 2026 ecosystem has documented real compromises: Axios npm supply-chain compromise (March 2026, used in this project), TanStack npm compromise (May 2026, `@tanstack/react-query` used in this project), Express security releases including Multer issues (February 2026, `multer: ^2.0.2` specified). A compromised dependency can exfiltrate `JWT_SECRET`, `SHKEEPER_WEBHOOK_SECRET`, `OPENAI_API_KEY`, or inject malicious code into payment flows. The backend currently has no lockfile pinning verification, no npm provenance checking, and no dependency audit CI step. |
| **Current state** | Partially mitigated (some packages may be updated) |
| **Required mitigation** | (1) Pin all dependencies with lockfile; verify lockfile integrity in CI. (2) Enable npm provenance/signature verification where available. (3) Run `npm audit` / `yarn audit` in CI; fail on high/critical CVEs. (4) Review and update `multer` to >= 2.1.0. (5) Implement a secure build and supply-chain policy (see [[Backend Stack Security and Refactor Assessment - 2026-05-24]] doc 10). (6) Consider extracting security-critical backend code to Go/Kotlin with smaller dependency footprint. Reference: [[Backend Stack Security and Refactor Assessment - 2026-05-24]] supply-chain section. |
### T15 -- CSRF on State-Changing Endpoints
| Field | Value |
|---|---|
| **STRIDE** | Cross-site request forgery |
| **Affected assets** | User account settings, payment actions, admin operations |
| **Actors** | Unauthenticated attacker (via victim browser) |
| **Description** | The current architecture uses JWT in the `Authorization` header (not cookies), which provides inherent CSRF protection because browsers do not automatically attach `Authorization` headers on cross-origin requests. However, if the planned migration to `httpOnly` cookies for refresh tokens (recommended in T04) is implemented without CSRF tokens, the refresh endpoint becomes vulnerable to CSRF. Additionally, if any endpoint accidentally reads tokens from cookies or query parameters, CSRF becomes possible. |
| **Current state** | Mitigated (JWT in Authorization header) |
| **Required mitigation** | When migrating to `httpOnly` cookies: (1) Implement CSRF token (double-submit cookie or synchronizer token). (2) Apply `SameSite=Strict` or `SameSite=Lax` on cookies. (3) Verify `Origin` header on state-changing requests. (4) Ensure CORS is not overly permissive. Reference: [[Security Architecture]] section 4. |
### T16 -- Deep-Link / Parameter Tampering (Telegram Surface)
| Field | Value |
|---|---|
| **STRIDE** | Tampering / Spoofing |
| **Affected assets** | User identity, referral attribution |
| **Actors** | Unauthenticated attacker |
| **Description** | The Telegram Mini App surface accepts `initData` from the Telegram WebApp SDK. If the backend does not cryptographically verify `initData` using the Telegram Bot token, an attacker can forge the user identity, impersonate other Telegram users, or tamper with referral parameters in deep links (`/r/:code` redirect at `app.ts:274-278`). The referral code is passed as a query parameter and is not validated against a signed token. |
| **Current state** | Partially mitigated (verification status depends on implementation) |
| **Required mitigation** | (1) Verify Telegram `initData` signature using HMAC-SHA256 with the Bot token on every Mini App request. (2) Validate referral codes server-side before applying. (3) Do not trust client-supplied userId from Telegram context without signature verification. |
### T17 -- Payment Provider Outage / Chain RPC Outage
| Field | Value |
|---|---|
| **STRIDE** | Denial of service |
| **Affected assets** | Payment processing, escrow operations, user experience |
| **Actors** | Infrastructure failure (non-malicious) |
| **Description** | The platform depends on two external systems for financial operations: (a) SHKeeper gateway at `pay.amn.gg` for pay-in address allocation and payout execution; (b) BSC/Ethereum RPC (`bsc-dataseed.binance.org`) for transaction verification. If SHKeeper is down, new pay-in intents cannot be created (the code falls back to a demo URL in this case). If the RPC is down, Web3 payment verification cannot complete. The circuit breaker (`shkeeperFetch` in `shkeeperHealthCheck.ts`) trips after repeated failures, but the fallback is a demo URL, not a graceful degradation. Public BSC RPC endpoints are rate-limited. There is no dedicated RPC provider. |
| **Current state** | Partially mitigated (circuit breaker and wallet monitor exist as fallbacks) |
| **Required mitigation** | (1) Use a dedicated RPC provider (Ankr, QuickNode, Alchemy) with SLA guarantees. (2) Implement retry with exponential backoff for verification. (3) When SHKeeper is down, return a clear error to the buyer instead of a demo URL. (4) Store pending verifications for reconciliation when service resumes. (5) Document operational runbooks for provider outage. Reference: [[Payment Flow - SHKeeper]], [[Payment Flow - DePay & Web3]]. |
### T18 -- Insider Fund Manipulation
| Field | Value |
|---|---|
| **STRIDE** | Tampering / Repudiation |
| **Affected assets** | Escrow funds, payment records |
| **Actors** | Insider threat (admin, operator, developer) |
| **Description** | The escrow wallet is a single custodial BSC address controlled by the platform operator. The private key has unrestricted access to all in-flight escrowed funds. Admin users can initiate manual payouts via the `admin-wallet-payout.tsx` UI by connecting their wallet and signing transfers directly. There is no multi-signature requirement, no dual-approval for large payouts, no immutable audit ledger, and no automated anomaly detection on payout patterns. A single insider with access to the escrow private key or an admin session can drain all escrowed funds. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Move escrow wallet to a multi-sig solution (e.g., Gnosis Safe) requiring at least 2-of-3 signatures for any transfer. (2) Implement two-person approval for payouts above a configurable threshold. (3) Build an immutable funds ledger so every debit/credit is append-only and auditable. (4) Implement real-time alerting on unusual payout patterns. (5) Store one key in HSM. (6) Separate admin UI access from wallet signing capability. Reference: [[Escrow Flow]] custodial risk warning, [[Payout Flow]], [[Backend Stack Security and Refactor Assessment - 2026-05-24]] Phase 2. |
### T19 -- Seller Price Manipulation After Offer Acceptance
| Field | Value |
|---|---|
| **STRIDE** | Tampering |
| **Affected assets** | Payment amounts, escrow funds |
| **Actors** | Seller |
| **Description** | The Negotiation Flow documents that "`updateOffer` does not enforce status... Current code allows the price change, which is dangerous post-payment." A seller can modify the offer price after the buyer has already paid, potentially inflating the amount or changing terms. The escrow holds the original amount, but the displayed/agreed amount could be tampered with. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Reject `updateOffer` if `status !== 'pending'`. (2) Snapshot offer amount at payment creation time in the Payment document. (3) Use the Payment-embedded amount for all downstream operations, not the live offer. Reference: [[Platform Logical Audit - 2026-05-24]] Finding 18. |
### T20 -- Delivery Confirmation Brute Force
| Field | Value |
|---|---|
| **STRIDE** | Spoofing |
| **Affected assets** | Escrow release trigger |
| **Actors** | Buyer |
| **Description** | The delivery confirmation code is a 6-digit number (`Math.floor(100000 + Math.random()*900000)`) with 900,000 possible combinations. There is no rate limiting on verification attempts. The "manual fast-track" allows the buyer to confirm delivery at any time, even before the seller has shipped. A buyer could brute-force the confirmation code to trigger release without actually receiving the item. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Add Redis-backed rate limiting on delivery code verification (e.g., 5 attempts per 15 minutes per request). (2) Increase code entropy (alphanumeric, longer). (3) Restrict fast-track confirmation to `status: 'delivery'` only. (4) Add time-based invalidation. Reference: [[Platform Logical Audit - 2026-05-24]] Finding 8. |
### T21 -- Unauthenticated Data Exfiltration
| Field | Value |
|---|---|
| **STRIDE** | Information disclosure |
| **Affected assets** | User personal data, payment history, notifications |
| **Actors** | Unauthenticated attacker |
| **Description** | Multiple endpoints accept a `userId` parameter without authentication or ownership verification: `GET /api/payment/decentralized/history/:userId` returns any user's payment history; the legacy notification router accepts `?userId=` query parameter allowing notification read/modify for any user. The payment history endpoint exposes transaction hashes, amounts, counterparties, and wallet addresses. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Add Bearer JWT authentication to all data-access endpoints. (2) Enforce ownership: the authenticated user's ID must match the requested `userId` (or require admin role). (3) Audit all parameterized routes for missing auth middleware. Reference: [[Platform Logical Audit - 2026-05-24]] Finding 3. |
### T22 -- Verification Code Leakage via Logs
| Field | Value |
|---|---|
| **STRIDE** | Information disclosure |
| **Affected assets** | User credentials |
| **Actors** | Insider threat, log viewer |
| **Description** | The registration and password reset controllers log the generated 6-digit verification code to stdout via `console.log` in all environments, including production. Anyone with access to application logs (CloudWatch, Sentry breadcrumbs, docker logs) can read these codes and take over unverified accounts or reset passwords. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Guard all verification code logging behind `if (NODE_ENV !== 'production')`. (2) Implement a log redaction formatter that strips sensitive fields. (3) Audit all `console.log` and `logger` calls for sensitive data. Reference: [[Registration Flow]] warning. |
### T23 -- Payment State Machine Inconsistency
| Field | Value |
|---|---|
| **STRIDE** | Tampering / Repudiation |
| **Affected assets** | Payment records, escrow state |
| **Actors** | Race conditions, software bugs |
| **Description** | The platform has multiple overlapping state machines for the same entities. Payment has both `status` and `escrowState` that must remain consistent. The Dispute entity has three mutually incompatible status/action enum sets across the Data Model, API Reference, and Flow documents. The PurchaseRequest has different status enums across three documents. Ghost states exist (`confirmed`, `partial`, `finalized`, `archived`) that no automated flow sets. This inconsistency creates opportunities for state confusion where a payment appears in one state from one code path and a different state from another. |
| **Current state** | Vulnerable |
| **Required mitigation** | (1) Create a single canonical enum set for each entity, documented in one place. (2) Enforce valid transitions in a centralized state machine service. (3) Reject invalid transitions at the service layer, not just the controller. (4) Remove ghost states or document the transitions that set them. Reference: [[Platform Logical Audit - 2026-05-24]] Findings 5, 9, 20, 21. |

## 7. Assumptions and Constraints
### 7.1 In scope
- The Express 5 backend API server and all routes documented in [[Backend Architecture]].
- The Socket.IO realtime layer as documented in [[Real-time Layer]].
- The SHKeeper payment integration (pay-in webhook, payout API).
- The Web3/direct-wallet payment path (on-chain verification).
- The escrow state machine and fund custody model.
- The dispute lifecycle and its interaction with escrow.
- Authentication flows (email/password, Google OAuth, passkey/WebAuthn).
- Admin operations surface (dashboard, manual payouts, user management).
- Frontend token storage and session management.
- Infrastructure: single Docker host, CloudFlare/Nginx proxy, Watchtower deployment.
- npm supply chain for both frontend and backend.
- Telegram Mini App integration surface.
### 7.2 Out of scope (for this iteration)
- Physical security of hosting infrastructure.
- Social engineering attacks against platform operators (addressed partially by insider threat mitigations).
- Cryptographic weaknesses in blockchain protocols (BSC, Ethereum assumed secure).
- SHKeeper application internals (assumed to be a trusted component operated by the platform).
- Third-party email provider security (SMTP provider assumed secure).
- Client-side malware on user devices.
- Regulatory compliance (KYC/AML requirements not covered here).
- DNS hijacking (mitigated by CloudFlare proxy assumption).
### 7.3 Assumptions
1. **Hosting is a single Docker host** behind CloudFlare with Nginx. Internal service-to-service communication (MongoDB, Redis) is on localhost without TLS. This is acceptable for a single-host deployment but must be revisited if the architecture scales to multiple nodes.
2. **CloudFlare provides DDoS mitigation and TLS termination.** The threat model assumes HTTPS is enforced externally and the Nginx-to-Express hop is HTTP on localhost.
3. **SHKeeper is self-hosted and under platform control.** The webhook secret is shared only between the backend and the SHKeeper instance. If SHKeeper is compromised, webhook integrity is lost.
4. **MongoDB and Redis are not exposed to the internet.** They are bound to localhost on the Docker host. If this assumption is violated (e.g., misconfigured Docker network), the entire data layer is exposed.
5. **The escrow wallet private key is stored securely by the platform operator.** The threat model assumes the key is not in the codebase or env files. If this assumption is wrong, the exposure is total.
6. **Admin accounts are created via bootstrap seed and manually.** There is no self-service admin creation flow. The seed admin credentials must be rotated before any public launch.
7. **The frontend is a Next.js application served from the same origin or a CORS-allowlisted origin.** Cross-origin access is restricted by the CORS configuration. This assumption must hold for CSRF protection via `Authorization` header to be effective.
### 7.4 Constraints
1. **Single-host deployment limits defense-in-depth.** Network segmentation between services is not possible on a single host.
2. **No background job queue.** All async work is inline with request handlers or uses `setTimeout`/`setInterval`. This limits the ability to implement reliable retry, reconciliation, and scheduled operations.
3. **No external penetration testing has been performed.** All findings are based on code review and documentation analysis.
4. **Documentation and implementation may diverge.** Several findings in the [[Platform Logical Audit - 2026-05-24]] show that documentation describes security controls that may not be implemented in code. This threat model is based on documented behavior and known gaps; the actual attack surface may be larger.
5. **The platform is in pre-launch state.** Many security controls are documented as recommended but not yet implemented. This threat model reflects the current state, not the target state.

## Description
Prepare the Telegram app and bot for controlled release.
## Details
Test Telegram iOS, Android, Desktop, Web, light/dark themes, compact/fullscreen modes, slow network, blocked bot, expired sessions, and payment cancellation. Keep sandbox/test bot and production bot environments separated. Roll out through feature flags, internal allowlist, beta cohort, and production enablement. Track activation, linked accounts, request creation, offer response, payment start/completion, dispute activity, release approval, and notification opt-outs. Add runbooks for bot outage, Telegram API outage, payment provider outage, stuck payment, duplicate callback, suspicious wallet proof, and compromised bot token.
## Verification
See Telegram-native PRD acceptance criteria.

## Description
Create a Telegram bot plus Mini App surface so users can complete Amanat buyer, seller, escrow, chat, dispute, payment, release/refund, and support workflows from inside Telegram.
## Details
Source PRD: .taskmaster/docs/prd-telegram-native-app-bot-wallet.md. Keep this as a separate delivery track from security remediation and Request Network migration. Identity, bot navigation, Mini App shell, and notifications can start behind flags; wallet/payment crediting and release/refund actions must use canonical backend authorization, provider adapter, funds ledger, escrow state machine, idempotency, and dispute holds.
## Verification
Use Telegram sandbox and production bot separation, Mini App client matrix testing, provider/wallet payment fixtures, backend authorization and ledger invariant tests, webhook/callback replay tests, and staged rollout analytics before launch.
