ZUMRI Current Backend Status

Phase 4 Completion Update

Completion date: 2026-09-03. Module 03 (product catalogue) is approximately 84%; Module 04 (multi-language content) is approximately 82%. Phase 4 adds 18 catalogue models covering brands, hierarchical localized categories, products/translations/multi-category joins, DECIMAL-price variants, configurable options and attributes, owned media, scheduled localized collections, structured size guides, explicit relations, and moderated reviews.

Public APIs now provide active/public product lists and slug detail, safe search/filter/sort/pagination, locale fallback, categories, brands, current collections, signed media DTOs, price ranges, and approved review summaries. Permission-gated admin APIs cover product lifecycle, variants/options/media/relations, brands, cycle-safe categories, collections, size guides, and review moderation. No inventory quantity, wholesale pricing, promotion, or shopping behavior was introduced.

The mocked regression suite passes 15 suites/78 tests and syntax validation covers 204 JavaScript files. The Phase 4 migration is forward-only and was not executed. Restored-staging migration checks, permission seeding, real MySQL query/concurrency testing, and signed-media volume validation remain required before Phase 5. See Documentation/PHASE_4_CATALOGUE_CONTENT.md and Documentation/API_CATALOGUE.md.

Phase 3 Completion Update

Completion date: 2026-09-03. Module 02 (customer profile/address management) is now approximately 88%; Module 13 (business accounts) is approximately 78%. Customer profile/preferences, structured owned addresses with transactional defaults, secure self-deactivation, business applications, permission-gated transactional approval, immutable partner identity, business profiles/contacts/addresses, domain status, DECIMAL credit configuration, and settlement-term primitives are implemented.

Security impact: all customer resource identity is derived from Phase 1 authentication; mutation schemas are strict; profile media is owner-validated; address/application IDOR is constrained in queries; approval/deactivation revoke sessions after identity-boundary changes; and business financial/review fields are excluded from self-service. Six models were added and two existing models extended. Customer/business and admin APIs are documented in Documentation/API_CUSTOMER_BUSINESS.md.

The complete mocked regression suite passes 12 suites/57 tests, and syntax validation passes 171 JavaScript files. The Phase 3 migration is forward-only and was not executed. Staging must resolve legacy business/profile/address pre-checks, seed/grant permissions, and validate MySQL concurrency plus Redis/S3/SMTP flows before Phase 4. See Documentation/PHASE_3_CUSTOMER_BUSINESS_FOUNDATIONS.md.

Phase 2 Completion Update

Completion date: 2026-09-03. Phase 2 hardens the existing shared-service foundation without adding commerce domains. Module 14 (notifications) is now approximately 72%; Module 19 (file/media) 82%; Module 20 (audit/config/logging) 68%; and Module 21 (background jobs) 78%. The document subsystem is approximately 82%.

Storage now has a reusable S3/S3-compatible boundary, actual-content validation, controlled keys, checksums, owner/status metadata, compensation, and authorization-safe signed URLs. Email is routed through BullMQ with delivery status and final-failure persistence. Notifications have fixed aliases, unique assignment migration, self-only inbox/read operations, announcement support, and preference policy. Queue defaults, idempotent job IDs, Bull Board registration, safe failure handling, stronger append-only activity records, and structured redacted logs are in place. Documents now have ownership, controlled registry validation, persisted generation lifecycle, safe status, and non-destructive signed download.

The full mocked suite contains 10 suites/40 tests and passes; syntax checks cover 153 JavaScript files. The new migration was not executed. Remaining work is staging migration/data pre-checks plus real MySQL, Redis, S3-compatible, SMTP, PDF/browser, retention-volume, and concurrency validation. After those operational checks and permission seeding, it is safe to begin Phase 3. See Documentation/PHASE_2_CROSS_CUTTING_SERVICES.md and Documentation/API_CROSS_CUTTING_SERVICES.md.

Audit date: 2026-09-03
Scope: repository source, configuration, lockfile, existing documentation, safe syntax/test/dependency checks. No database, Redis, S3, email, or other external service was mutated.

1. Executive Summary

This repository is an early modular-monolith foundation, not yet an e-commerce backend. It contains working-shaped user registration/email verification, OTP login, basic profiles, RBAC tables/controllers, notifications, activity logging, S3 upload plumbing, document generation, Redis/BullMQ workers, and one cron. Important pieces are incomplete or broken in integration. The estimated completion against the 25-module ZUMRI target is about 12%.

No original development-plan day is fully complete. Day 1 is approximately 55%: Express, Sequelize/MySQL, Redis/BullMQ, a Dockerfile, and a health route exist, but Swagger, robust health checks, Node 22 alignment, production bootstrap/error handling, Compose/Nginx, migrations, and tests do not. Day 2 is approximately 38%; Day 3 approximately 18%; notification/job/file/document/audit foundations from later days were built early.

The code still carries prior-project terminology (Oceanic Titan, oceanic-db, Oceanic demo URL) and role names that conflict with the actual user ENUM. Future work should preserve usable primitives, but first complete and secure foundation/authentication.

Status terms: COMPLETE = end-to-end implementation is credible from source; PARTIAL = meaningful code exists but requirements/integration are incomplete; STUB = structure only; MISSING = no implementation; BROKEN = known source/integration defect.

2. Current Architecture

• server.js loads .env, imports app.js, and listens on 0.0.0.0:${PORT|3070}.
• app.js authenticates Sequelize and calls unrestricted sequelize.sync() in an unawaited startup IIFE, then starts cron jobs. The HTTP listener starts independently, so requests can arrive before database readiness, and DB failure does not stop the process.
• Middleware order is cookie parser, CORS, JSON parser, Morgan, /health, /api, static documentation, then Bull Board. There is no URL-encoded parser, request ID, Helmet, compression, rate limiting, global 404 handler, or global error handler.
• API base path is /api (not versioned). Routes delegate mostly directly to Sequelize-backed controllers; there is only a permission service and activity service.
• Redis connections are created at module import. One shared client is used by queues/workers, while password reset and S3 utilities create additional clients.
• Workers are a separate npm run worker process. The server does not start them. Activity, log, and document consumers exist.
• Cron runs in every API process after DB sync; there is no distributed lock, so multi-instance deployments duplicate scheduling.
• Sequelize models are registered centrally and their associate functions are invoked. No migrations are present.
• Environment keys exist locally; .env is ignored/untracked. .env.sample is tracked. No actual secret values are reproduced here.

Bootstrap and operational findings

Concern	Status	Evidence / impact
Express start and base path	Partial	server.js, app.js; /api and /health
JSON / cookies / CORS / logging	Partial	JSON, cookies, single-origin credentialed CORS, Morgan dev; no body-size configuration or URL-encoded parser
Security middleware	Missing	No Helmet or API rate limiter
404/global errors	Missing	Errors depend on individual controllers; unmatched routes use Express defaults
Database readiness	Broken	Listener is not gated on authenticate/sync; failure is logged only
Redis readiness	Partial	Event logging exists; health endpoint never checks Redis
BullMQ/workers	Partial	Separate process required and undocumented operationally; retries only on document jobs
Cron initialization	Partial	Starts after DB sync, once per server process, with no leader lock
Health check	Broken	Sends response before asynchronous DB authentication completes and hardcodes mail/Redis as OK
Graceful shutdown	Missing	No SIGTERM/SIGINT cleanup for server, Sequelize, Redis, workers, or cron
Process errors	Missing	No unhandledRejection/uncaughtException policy

3. Existing Infrastructure

Component	Status	Files	Notes
Express API	Partial	server.js, app.js, app/routes/*	Express 5; no versioning/global errors/security middleware
MySQL/Sequelize	Partial	app/config/db.config.js, app/models/index.js	Pool configured; runtime sync(), no migrations
Redis	Partial	redis.config.js, redisClient.js	Functional client pattern; excessive clients, no shutdown/readiness
BullMQ	Partial	app/queues/*, app/workers/*	Three queues and matching consumers; only document jobs have attempts/backoff/retention
Bull Board	Broken/unsafe	bullBoard.config.js, app.js	Only activity queue shown; /admin/queues has no authentication
Cron	Partial	cron/*	Transactional notification deletion; no distributed lock or retention-age policy
Email	Partial	mail.config.js, mail.util.js, templates	SMTP/template sender exists; verifies on import, sends inline, no queue/retry/escaping
S3 storage	Broken	s3.config.js, s3Upload.utill.js	S3 client is entirely commented out, so s3.send fails
Uploads	Broken	upload middleware/controller/model	MIME/size checks exist; account guard is incompatible; no magic-byte validation/cleanup/ownership
Documents	Partial/broken	document controller, logic, templates, queue/worker	PDF/Excel framework is substantive; S3 breaks completion; access is overly broad and role guards mismatch
Notifications	Partial	notification models/controller/cron	In-app records only; no assignment API/service, email/FCM/preferences/delivery tracking
Activity/audit	Partial	activity service/model/queue/worker/controller	Async append-only-shaped records; no actor/IP/change metadata, integrity/retention, or broad coverage
Logging	Partial	console utility/log queue/worker	Local daily files; may receive sensitive payloads; no rotation/structured sink
API docs	Partial	Documentation/*, docs routes	Handwritten Markdown/HTML, not Swagger/OpenAPI; docs auth is forgeable
Tests	Missing	package script only	Jest finds zero tests; Supertest is not installed
Docker	Partial	Dockerfile	Uses Node 20 instead of target Node 22; API image only; no healthcheck/non-root user
Nginx/Compose/CI/CD	Missing	none	No reverse proxy, service orchestration, or pipeline files
Payments/FCM/OpenAI	Missing	none	No dependencies, config, models, or consumers

Queue behavior: document-generation has 3 exponential attempts (2s base), completed retention, and retained failures. activity-queue and logQueue have consumers but no explicit retry/backoff/retention/dead-letter policy and are not idempotent. Re-delivery can duplicate activity rows or log lines. Queue event listeners attached to Queue are not a reliable substitute for QueueEvents for all lifecycle events. Worker failures are logged only. Document status is not reconciled on job failure/success.

4. Existing Database Models

All models use timestamps and none uses paranoid. Aside from the unique flags noted below, explicit indexes are absent.

Model / table	Key and important fields	Purpose	Important relations	Status
User / users	PK string id; names, unique email, password, accountType ENUM, accountStatus ENUM, emailVerifiedAt	Identity/account	hasOne Profile; hasMany UserPermission	Partial; no role FK/roleID despite service/controller use, no sessions/tokenVersion/social IDs
Profile / profiles	PK profile_id; unique user_id; theme, notificationsEnabled, image IDs, DOB, phone	Basic preferences/profile	belongsTo User	Partial; no gender/language/address; image IDs lack FKs
UserActivity / UserActivity	integer PK; user/name/description/type/module/date/time	Activity trail	None	Partial; user FK absent, redundant time fields, no indexes
Upload / uploads	integer PK; S3 path/type/size/name/use/uploaded_by	Media metadata	None	Partial; uploader/user and ownership FKs absent
Permission / permission	PK permission_id; name/page/module/action	Permission definition	hasMany role/user grants	Partial
Role / roles	PK role_id; name/description	Named role	hasMany role grants	Partial; User has no role association
RolePermission / rolePermission	PK rp_id; role_id, permission_id	Role grant	belongsTo Role/Permission	Partial; no composite unique constraint
UserPermission / userPermission	integer PK; user_id, permission_id	Direct additive grant	belongsTo User/Permission	Partial; no composite unique; cannot deny/expire grants
Document / Document	PK doc_id; reference_no, doc_type, JSON data, status	Saved business documents	None	Partial; status/type unconstrained, no creator/owner/FKs/indexes
DocumentType / DocumentType	integer PK; nullable name, JSON description	Document registry metadata	None	Partial; name is neither required nor unique
ReferenceNumber / referenceNumbers	PK string; unique sequence_key, integer counter, last value	Atomic sequence generation	None	Reusable; transaction/row locking implemented by utility
Notification / notification	PK string; headline/body, USER/ANNOUNCEMENT ENUM, active/date	In-app notification content	hasMany UserNotification as users	Partial
UserNotification / user_notification	integer PK; user_id, notification_id, isRead	Per-user notification state	belongsTo User; belongsTo Notification	Partial; constraints disabled, no composite unique/index; include alias is inconsistent (controller asks notification, association defines no alias)

Association registration does execute. However, User's roleID is not a declared attribute or FK, notifications deliberately disable FK constraints, activities/uploads/documents have no user association, and join-table uniqueness is not enforced. sequelize.sync() masks the absence of schema migrations and makes production schema evolution unsafe.

5. Existing API Endpoints

All paths below are derived from actual mounting. “Self-or-admin” is not implemented anywhere; parameterized user endpoints generally trust the requested ID after coarse account-type checks.

POST	/api/profile/req-reset-password	No	None	Partial/unsafe logging	Enumeration-resistant response; raw reset token is logged
POST	/api/profile/reset-password	No	None	Partial	Hashed one-use Redis token; new password is not policy-validated
POST	/api/profile/change-password	Yes	legacy account types	Broken/partial	Effectively admin-only; no new-password validation/session revocation

PATCH	/api/notification/user/:userId/notification/:notificationId/read	Yes	legacy account types	Broken/IDOR	No ownership; effectively admin-only
ALL	/admin/queues/*	No	None	Unsafe	Bull Board exposed; only activity queue registered
GET	/Documentation/*	No	Blocks .md only	Partial	Static HTML documentation is public

Defined but unreachable permission routes

app/routes/permission.routes.js defines 18 endpoints under the intended permission router (permission CRUD/bulk; role CRUD and grants; user grants CRUD/bulk), but app/routes/index.js imports permissionRoutes and never calls router.use(...). Therefore none has an actual URL and all are BROKEN/unreachable. If mounted as /permission, their paths would be /, /bulk, /:permissionId, /roles, /roles/:roleId, /roles/:roleId/permissions, /roles/permissions/bulk, /users/:userId/permissions, /users/permissions, /users/permissions/bulk, and /users/permissions/:upId with the methods declared in that file. Read endpoints require authentication; mutations require accountType exactly admin. Controllers are substantial CRUD logic, but integration, uniqueness, cache invalidation, validation, and transactions are inconsistent.

9. Technical Debt

CRITICAL

• Restore a valid S3 client before any upload/document endpoint can work.
• Align authorization vocabulary and enforce ownership; current legacy guards, IDORs, and accountType mutation enable denial of access or privilege escalation.
• Remove raw OTP/reset-token and decoded-auth logging; rotate any credentials if operational logs captured them.
• Replace production sequelize.sync() with migrations and gate server readiness on required services.
• Implement a real access/refresh session model with rotation, revocation, account-status enforcement, and secure logout.

HIGH

• Mount and repair permission routes; add User-role linkage and grant uniqueness/cache invalidation.
• Add validation schemas and centralized error handling; prevent arbitrary field updates.
• Protect Bull Board and documentation sessions.
• Fix notification association alias and user ownership checks.
• Add rate limits for login, OTP, verification, reset, docs login, and general API traffic.
• Add tests for auth/authorization, transactions, uploads/jobs, and failure paths.
• Fix transaction leaks on early returns in user update/delete.

MEDIUM

• Standardize response/error formats and status codes; stop returning internal error messages/stack traces.
• Consolidate Redis connections and add lifecycle/readiness handling.
• Make jobs idempotent and add retry/backoff/retention/dead-letter/alert policies.
• Move email to a job and add retry/delivery tracking and safe template escaping.
• Add pagination/indexes to activity, notification, document, and user queries.
• Remove legacy Oceanic naming and reconcile API versioning.

LOW

• Correct mojibake in source/log messages, inconsistent singular/plural table names, and *.utill.js spelling.
• Remove unused imports/constants and dead/commented code.
• Split giant permission controller and move business logic into services after behavior is tested.

10. Security Findings

• No tracked .env was detected. .env.sample is tracked. Potential secret-bearing configuration exists in local .env; values were not inspected/reproduced. If this file has ever been shared or committed elsewhere, rotate credentials.
• JWT falls back to a public placeholder secret if configuration is missing. There is no issuer/audience/session ID/tokenVersion or refresh-token revocation.
• Login OTP uses Math.random, process memory, and no attempt/rate limit; it fails across instances/restarts and is logged in plaintext.
• Password reset token is logged in plaintext. Reset/change paths do not validate the new password policy or revoke existing access tokens.
• Login does not reject pending, suspended, or deactivated accounts.
• User update allows coarse-authorized callers to target arbitrary IDs and set accountType, a privilege-escalation and IDOR risk. Many profile/notification/document endpoints have the same ownership defect.
• Bull Board is public. Docs protection is an unsigned client cookie equal to true; credentials are brute-forceable without rate limiting.
• CORS is a single credentialed origin and cookie flags are reasonable for cross-site production, but CSRF protection/origin validation is absent for cookie-authenticated mutations.
• Multer limits size and declared MIME, but image wildcard acceptance lacks content sniffing, image decompression safeguards, antivirus scanning, extension normalization policy, and object lifecycle cleanup.
• S3 PutObject sets no ACL (good default if bucket blocks public access), but actual bucket policy/encryption cannot be verified. Signed URLs are cached; authorization is checked only before URL issuance and ownership is not checked.
• Controllers expose error.message; job status exposes stack traces. Production Sequelize logging is inverted to true, which can leak query data.
• Request validation is handwritten and sparse; mass assignment exists in user update. Sequelize query values are generally parameterized, so no direct raw-SQL injection was found.
• Foreign-key constraints are disabled for notification joins; missing uniqueness and transactions create races/duplicates in grants and notifications.
• No Helmet, API rate limiting, CSRF strategy, audit integrity, session revocation, or centralized security error policy exists.

11. Broken / Suspicious Implementations

• app/config/s3.config.js: the entire client/export is commented; every S3 caller receives {}.
• app/routes/index.js: imports permissionRoutes but never mounts it.
• app/utils/documentJob.util.js: requires nonexistent ../queues/pdf.queue; currently appears orphaned.
• app/services/permission.service.js#getEffectivePermissions: queries user.roleID, which is not a User model attribute; role grants cannot reliably apply.
• app/routes/{user,profile,document,notification}.routes.js: guards use management, team_head, user, or staff, none of which is in the User ENUM. Valid manager, customer, business_customer, rider, support_agent, and superadmin are largely excluded.
• user.controller#createNewUser: calls logActivity({user: req.user}) on a public route, causing a post-commit exception after the account has been created; client may receive 500 and retry.
• user.controller#updateUser: accepts accountType and undeclared role/department fields; does not update email despite destructuring it; opens transaction before lookups and does not roll back early 404 responses.
• user.controller#deleteUser: early 404 does not roll back; hard delete may conflict with Profile because cascade is unspecified.
• profile.controller#getProfileAvatar/getProfileBackgroundImage: assumes upload exists, uses wrong profile.userId response property, lacks ownership, and reaches broken S3.
• upload.controller#getFileUrl: empty catch block can leave requests hanging.
• notification.controller#getUserNotifications: requests association alias notification, but belongsTo defines no alias; likely Sequelize eager-loading error.
• notification.controller: USER notifications are created but never assigned to users through an endpoint/service.
• app.js#/health: asynchronous DB result races with response; reports N/A/hardcoded OK rather than real readiness.
• app.js bootstrap: server listens before DB boot finishes; DB errors are swallowed; each instance starts cron.
• app/middleware/permission.middleware.js: unused hasPermission; admin bypass only recognizes admin, not superadmin; wildcard logic differs between helper and actual check.
• docsSession.middleware.js: trusts an unsigned, client-set boolean cookie.
• document.controller#getSavedDocuments: exclude is not nested under attributes, so JSON data may still be fetched; filter is in POST body despite message saying query parameter.
• document.controller#downloadDocument: destructive read deletes the object after delivery and lacks job/user ownership.
• app/logic/documents/registry.js: catches module load failure but still registers undefined functions, deferring failure to runtime.
• consoleLog.utill.js and auth/reset utilities: log pipelines may persist secrets and full error objects.
• Production DB logging is enabled while non-production logging is disabled, likely inverted.

Orphaned or unused-looking code includes documentJob.util.js, notification.utill.js (empty), logic/documents/engine/pdf.engine.js (generation uses pdfGenerator.js), several Excel/id/vendor/calendar/basis utilities not referenced by mounted features, Assets in upload controller (unregistered), imported PERMISSIONS/checkPermission in routes where checks are absent/commented, and unused dependencies likely including pdfmake and nodeman. nodemon is incorrectly a production dependency. Static analysis cannot prove every dynamic/template use; confirm before removal.

12. Reusable Existing Components

• Sequelize model registry/association convention can be extended after migrations replace runtime sync.
• User/Profile registration transaction, bcrypt utility, hashed one-use email verification token, and hashed password-reset-token concepts are sound foundations once error/logging/session issues are fixed.
• Cookie-or-Bearer authentication middleware structure is reusable after it loads current user/session/status and applies token claims.
• Permission, role, role-grant, and user-grant models/controllers/service are worth repairing rather than rebuilding; add role linkage, constraints, mounting, validation, and cache invalidation.
• Shared Redis factory/client and permission/user cache helpers can be consolidated and retained.
• Activity queue/service/worker is a useful async audit foundation; extend its schema and coverage.
• BullMQ worker entry pattern and document queue retry/backoff settings are reusable; standardize them across queues.
• Upload metadata model, Multer memory-storage limits, S3 key generation, and presigned URL caching are reusable after the S3 client and authorization/content validation are fixed.
• Document registry, PDF/Excel generators, templates, queue/worker, Document/DocumentType models, and atomic reference-number generator are substantive reusable subsystems. They are auxiliary business-document infrastructure, not order/payment replacements.
• Notification/UserNotification models, read-state concept, announcement query, and transactional cleanup cron can be repaired and extended for channel delivery.
• Email transport/template system and existing verification/reset/welcome templates can be moved behind an email queue.

13. Recommended Next Development Phase

Continue with a Foundation, security, and authentication completion phase before starting catalogue work.

First make startup deterministic and production-safe: Node 22 alignment, validated environment configuration, migrations, real readiness/liveness checks, global 404/errors, Helmet/rate limits, protected operations dashboards, graceful shutdown, and a test harness. Then complete identity: Redis-backed cryptographic OTP with limits, account-status checks, access/refresh sessions with rotation/revocation, secure logout/reset, validation, ownership rules, and a repaired/mounted role-permission system. Repair S3 only as part of restoring already-promised profile/media/document behavior.

After that baseline passes integration tests, finish customer/business profile and address primitives, reusing User/Profile, auth middleware, Redis, permission service, upload system, activity logger, email templates, queues, and reference-number utility. Only then begin catalogue/product models.

14. Recommended Updated Roadmap

11. Phase 10 — Support/AI/recommendations: Help content, tickets/SLA, advisor escalation, AI assistant, recommendation events/services.
12. Phase 11 — Analytics and production QA: Dashboards, security testing, load/integration/e2e tests, observability, Nginx/Compose/deployment/runbooks.

15. Do Not Rebuild List

Preserve and extend these concepts/files after adding tests: centralized Sequelize registration; User/Profile base tables; bcrypt helper; Redis connection/cache helpers; email verification/password-reset token hashing; auth middleware extraction of cookie/Bearer tokens; RBAC model/controller foundation; activity queue/service/worker; document registry/generators/templates/queue/worker; reference-number sequencing; Upload metadata/Multer limits/S3 utility interface; Notification/UserNotification read-state model; cleanup cron transaction; mail templates/transport interface; Docker Chromium setup for Puppeteer.

Verification and Dependency Audit

• node --check passed for every repository JavaScript file.
• npm test -- --runInBand failed because Jest found 0 tests.
• npm ls --depth=0 completed without reporting missing installed top-level packages.
• npm audit --omit=dev reported 28 production dependency vulnerabilities: 19 high, 8 moderate, 1 low, 0 critical. Dependency upgrades were intentionally not performed.
• Broken local import scan found active-looking documentJob.util.js -> ../queues/pdf.queue; the commented future email.worker reference is not an active defect.
• Targeted dependency observations: Supertest, Swagger/OpenAPI tooling, Helmet, rate limiting, FCM, payment SDKs, and OpenAI SDK are missing. nodemon should be dev-only; nodeman and pdfmake appear unused. Confirm with runtime coverage before removal.

Phase 0 Completion Update

Date: 2026-09-03 Revised Day 1 completion: approximately 92%.

Phase 0 stabilized the existing foundation without adding commerce modules. Node/Docker now target Node 22; Zod validates required startup configuration and feature-gated mail/S3 configuration; unsafe JWT secret fallbacks are removed. Express construction is independent from listening, and server.js waits for successful MySQL authentication and Redis connectivity before accepting traffic. Runtime sequelize.sync() was removed and Sequelize CLI plus a non-destructive current-model baseline migration were added.

New /health/live and /health/ready routes provide real liveness/readiness behavior, while /health remains a liveness compatibility alias. Request IDs, Helmet, explicit body limits, general and sensitive rate limits, centralized 404/error handling, safer production request logging, configurable cron startup, and API/worker graceful shutdown are now present. Bull Board requires an authenticated admin or superadmin and displays all three existing queues. The existing router is available on both /api and /api/v1.

Deployment additions include a hardened Node 22/Chromium/non-root Dockerfile with healthcheck, API/worker/MySQL/Redis Compose configuration, an Nginx reverse-proxy example, and a Gitea Actions CI baseline. Jest/Supertest tests now cover environment validation, liveness/readiness, errors/404, protected routes, Bull Board denial, and request correlation. The first test run exposed incompatible ESM-only uuid@13; it was safely pinned to CommonJS-compatible v11. nodemon moved to devDependencies.

Remaining foundation-adjacent work is intentionally deferred: production database baseline verification, distributed cron locking, full queue policy/idempotency, stronger documentation sessions, permission-router/role integration, and the Phase 1 authentication/ownership/security issues. The original audit above remains the historical baseline; statements such as “missing tests/Helmet/migrations” are superseded by this update and Documentation/PHASE_0_FOUNDATION_STABILIZATION.md.

Phase 1 Completion Update

Date: 2026-09-03 Authentication completion: approximately 91%. Revised Day 2 completion: approximately 90%.

Phase 1 replaced process-memory OTP and refresh sessions with Redis hash-only login challenges and durable MySQL auth-session families. OTP now uses crypto.randomInt, challenge UUIDs, TTL, atomic verification, bounded attempts, and no plaintext logging. Refresh tokens are opaque random values stored only by SHA-256 hash; row-locked transaction rotation detects replay and revokes the family. Access JWTs are short-lived, issuer/audience/algorithm constrained, and bound to sub, live session ID, and User token version. Middleware enforces current account state and session revocation.

New auth_sessions, user_identities, and user_roles models/tables support devices, Remember Me, Google/Apple stable subjects, and configurable roles. The User security migration adds token version/last login, expands canonical account types, and adds RBAC unique indexes. Permission routes are mounted behind SUPER_ADMIN, permission resolution now uses UserRole, and cache invalidation covers assignments/grants. Customer self-service update is allowlisted and ID-based mutation is privileged, closing the audited identity IDOR/mass-assignment path.

Auth endpoints now cover customer registration, verification/resend, password-to-OTP challenge, OTP completion, refresh rotation, current/all-device logout, forgot/reset/change password, Google, Apple, /me, and shared admin/rider compatibility flows. Both /api and /api/v1 remain. Security-focused unit/integration tests were added without real providers/email/database/Redis.

Remaining identity work is operational: validate/deduplicate deployed RBAC data before migration, run staging MySQL/Redis concurrency tests, seed initial privileged assignments securely, configure provider audiences/mail, and design manual privileged OAuth linking and email change if required. Module 01 is now approximately 91%; migration/staging validation prevents claiming 100% production completion.

Phase 5 Completion Update

Date: 2026-09-03. Inventory/reservation foundations, business pricing, promotions/coupons, and localized scheduled banners are implemented behind new permissions and a forward-only migration. Phase 5 adds 13 models, secured administration routes, public availability/banner projections, audit calls, a bounded expiry reconciliation cron, and Phase 6 pricing/reservation service boundaries. Module 05 is 85%, Module 07 is 78%, and Module 13 is 75%. Inventory is 90%, reservations 90%, business pricing 82%, promotions/coupons 78%, and banners 82%. Automated verification: 18 suites and 89 tests passed; syntax passed for 232 JavaScript files. Migration was not executed. Staging must precheck legacy stock/pricing/promotion/banner data, apply the migration, seed permissions/default warehouse, and test genuine MySQL locking plus cron behavior before Phase 6 production use.

Phase 6 Completion Update

Date: 2026-09-03. Module 06 is 91%, Module 08 is 84%, and Module 07 is revised to 86%. Authenticated cart is 92%, wishlist 92%, shipping 86%, checkout 88%, and reservation integration 90%. Nine models, a forward-only migration, owner-scoped shopping APIs, permission-protected shipping administration, server-authoritative totals, atomic inventory reservation composition, idempotent checkout creation, and bounded expiry/cancellation release are implemented. Verification passes 20 suites/95 tests and 258 JavaScript syntax checks. The migration was not executed. Before Phase 7, staging must precheck legacy shopping/shipping tables and address/currency compatibility, seed shipping configuration/permissions, apply migrations, and validate real multi-connection InnoDB concurrency plus multi-instance expiry behavior.

Phase 7 Completion Update

Date: 2026-09-09. Module 09 is 86%, Module 10 is 76%, and Module 13 is revised to 82%. Orders are 90%, payments 78%, invoices 72%, refunds 68%, returns 82%, coupon redemption 80%, and verified-purchase reviews 90%. Eleven commerce models, a forward-only migration, transactional checkout conversion, owner/admin APIs, explicit state machines, verified/idempotent webhook processing, payment-time inventory consumption, invoice sequencing, itemized refund validation, RMA handling, and return-only restocking were added. Migration and real provider/MySQL/document-worker validation remain staging requirements. Module 16 AI Customer Support Chatbot is intentionally excluded from this backend and planned as a separate service.
