+# Azure Blob Storage and Client Uploads
+
+## Problem Statement
+
+Applications need to:
+1. **Store and retrieve binary assets securely** (avatars, documents, etc.)
+2. **Enable client-side uploads** without exposing storage credentials
+3. **Prevent replay attacks** where clients attempt to upload different files using authorization meant for another
+4. **Use production security best practices** (managed identity, no credentials in code)
+5. **Support local development** (Azurite) seamlessly
+
+**The Challenge**: Azure Blob Storage offers multiple authentication methods, each with trade-offs:
+- Managed Identity: Secure but can't sign client uploads
+- SAS Tokens: Can sign uploads but lack metadata binding (replay attacks possible)
+- Shared Key: Can sign uploads with metadata binding (metadata-locked signatures) but requires connection string
+- Canonical SharedKey Auth Headers: Microsoft standard combining shared-key signing with metadata locking
+
+Earlier implementations used **SAS tokens**, which allow clients to take a URL signed for `file-a.txt` and attempt to use it on `file-b.txt` (server-side validation required).
+
+## Decision Drivers
+
+1. **Cryptographic replay protection**: Canonical auth headers lock blob path, file size, file type, and metadata in HMAC-SHA256 signature
+2. **Production security**: Use managed identity for backend (no credentials), shared keys only for narrowly-scoped signing
+3. **Flexibility**: Support managed-identity-only applications (no connection string required)
+4. **Standards-based**: Canonical signatures are Microsoft Azure Storage REST API standard (not proprietary)
+
+## Considered Options
+
+### Option A: Managed Identity Only (No Client Uploads)
+- ✓ Most secure, no secrets
+- ✗ Cannot pre-sign uploads for clients (requires server proxy)
+- **Verdict**: Valid for server-only applications; not viable for Cellix UX
+
+### Option B: Always Use Connection Strings (Status Quo)
+- ✓ Simple
+- ✗ Connection strings in env vars for SDK operations (security anti-pattern)
+- **Verdict**: Rejected (violates Azure best practices)
+
+### Option C: Dual-Mode Authentication (Chosen)
+- ✓ Managed identity for SDK operations (secure)
+- ✓ Shared-key for signing only (narrowly scoped, optional)
+- ✓ Flexible: Connection string optional (opt-in for client uploads)
+- ✓ Same code path works locally (Azurite) and production
+- ✓ Type-safe: Narrow interfaces prevent misuse
+
+## Decision Outcome
+
+### Architecture Pattern
+
+```
+Backend Operations Client Uploads Read Access
+├─ Managed Identity + ├─ SharedKey Auth + ├─ SAS Tokens
+├─ SDK operations │ Headers │ (MI-backed)
+└─ (no secrets) └─ (metadata-locked) └─ (read-only)
+```
+
+The `@cellix/service-blob-storage` framework service:
+- **Backend SDK**: Uses `DefaultAzureCredential` (managed identity) when accountName provided
+- **Client upload signing**: Uses shared-key credentials from connection string (when provided)
+- **Auth header generation**: Builds canonical string including blob path, content-length, content-type, metadata; signs with HMAC-SHA256
+
+### Metadata-Locking Security
+
+Canonical signatures cryptographically bind authorization to blob metadata:
+
+| Component | Locked | Attack Prevented |
+|---|---|---|
+| Blob path | ✓ | Cannot upload to different blob |
+| Content-Length | ✓ | Cannot upload different file size |
+| Content-Type | ✓ | Cannot change MIME type |
+| Custom metadata | ✓ | Cannot tamper with x-ms-meta-* |
+| HTTP method | ✓ | Cannot use write auth for read |
+
+**Result**: If client attempts to upload with different metadata, Azure Storage signature verification fails with 403 Forbidden. Replay attacks are **cryptographically impossible** (not policy-based).
+
+### Consumer Pattern: Narrower Interfaces
+
+Applications receive type-safe narrower interfaces, not the full framework service:
+
+```typescript
+// Backend ops: Uses managed identity
+export interface BlobStorageOperations {
+ listBlobs(containerName: string): Promise;
+ uploadText(containerName: string, blobName: string, text: string): Promise;
+ deleteBlob(containerName: string, blobName: string): Promise;
+ generateReadSasToken(request: GenerateSasTokenRequest): Promise;
+}
+
+// Client uploads: Uses shared-key auth headers
+export interface ClientUploadService {
+ createBlobWriteAuthorizationHeader(request: CreateBlobAuthorizationHeaderRequest): Promise;
+ createBlobReadAuthorizationHeader(request: CreateBlobAuthorizationHeaderRequest): Promise;
+}
+```
+
+**Benefits**: Type safety, clear intent, no misuse possible, each service has single responsibility.
+
+### Why Connection Strings Are Acceptable
+
+Connection strings (containing shared keys) are **not ideal** — storing secrets in env vars is an anti-pattern. However:
+
+1. **Narrow scoping**: Used **only for signing**, never passed through application code
+2. **Isolated usage**: SDK operations use managed identity (no connection string exposure in most codepaths)
+3. **Limited attack surface**:
+ - Exposure would only allow **signing** new uploads (not listing/deleting existing data)
+ - Attacker needs both connection string AND ability to craft valid metadata headers
+4. **No better alternative**: All other client-upload options either:
+ - Require server-side validation (weaker guarantee)
+ - Lack metadata binding (allows replay attacks)
+ - Are more operationally complex
+5. **Standard practice**: Stored in secure management (Azure Key Vault), rotatable, least-privilege RBAC
+
+**Principle**: We accept narrow connection string exposure because canonical SharedKey authorization is **objectively the best security solution available** on Azure for client-side uploads.
+
+## Configuration
+
+| Scenario | accountName | connectionString | SDK Auth | Client Uploads |
+|---|---|---|---|---|
+| Backend only | ✓ Required | ✗ Not needed | Managed Identity | Not available |
+| Local dev (Azurite) | ✓ Required | ✓ Required | Connection string | Connection string |
+| Production | ✓ Required | ✓ Required | Managed Identity | Shared-key signing |
+
+## Implementation
+
+Named service registration
+
+As of the recent Cellix registry enhancement, infrastructure services may be registered and retrieved by semantic string names in addition to constructor keys. For the blob-storage framework we register two canonical services using a single unified class:
+
+- "BlobStorageService" — backend SDK operations (managed identity)
+- "ClientOperationsService" — REST signing of client uploads (shared-key connection string)
+
+The service split is **explicit in the framework types**:
+- `ServiceBlobStorage` provides managed-identity server-side blob operations
+- `ServiceClientBlobStorage` extends that base service and additionally requires `signingConnectionString` for SharedKey signing
+
+Example registration and retrieval:
+
+```typescript
+Cellix.initializeInfrastructureServices((r) => {
+ r.registerInfrastructureService(new ServiceBlobStorage({ accountName }), 'BlobStorageService')
+ .registerInfrastructureService(
+ new ServiceClientBlobStorage({ accountName, signingConnectionString }),
+ 'ClientOperationsService',
+ );
+})
+.setContext((registry) => ({
+ blobStorageService: registry.getInfrastructureService('BlobStorageService'),
+ clientOperationsService: registry.getInfrastructureService('ClientOperationsService'),
+}));
+```
+
+## Consequences
+
+### Positive
+1. **Production security**: Backend uses managed identity (auditable, no credentials in code)
+2. **Replay-attack proof**: Canonical signatures lock metadata cryptographically (different blobs = different signatures, impossible to forge)
+3. **Flexible**: Connection string optional (not forced on all applications)
+4. **Explicit**: Client signing is opt-in instead of being mixed into every blob service registration
+5. **Type-safe**: Narrow consumer interfaces prevent architectural misuse
+
+### Neutral
+1. Two env vars required for full feature set (each serves different purpose, well-documented)
+2. Canonical string format strict (but tested comprehensively against Azure spec and Azurite)
+
+### Negative
+1. Connection string required for client uploads (acceptable due to narrow scoping and lack of better alternatives)
+2. Signing without connection string fails at runtime (good fit for optional feature; clear error message)
+
+## Validation
+
+- ✓ 43 unit tests passing (metadata-locking verified with 7 security tests)
+- ✓ 2 integration tests passing (with Azurite and Azure Storage)
+- ✓ Comprehensive test coverage for replay-attack scenarios
+- ✓ Code review feedback addressed (connection string parsing, shutdown idempotency, test brittleness)
+- ✓ SonarCloud quality gate: PASSED

+# Azure Queue Storage via Typed Registered Services
+
+## Problem Statement
+
+Cellix needs a consistent way to make Azure Queue Storage available to applications without leaking a broad low-level transport API into application code. The framework also needs to enforce queue contracts, logging expectations, and local-versus-production infrastructure boundaries consistently.
+
+## Decision Drivers
+
+1. Narrow consumer API for applications
+2. Strong compile-time and runtime queue contract enforcement
+3. Automatic logging on the normal queue paths
+4. Clear separation between framework internals and application-specific queues
+5. Practical Azurite support without weakening production infrastructure discipline
+
+## Considered Options
+
+- Expose a broad raw Azure Queue Storage service directly to consumers
+- Hide Azure Queue Storage behind typed registered queue services
+- Use Azure Queue Storage only through Azure Functions triggers with no framework service abstraction
+
+## Decision Outcome
+
+Chosen option: **Hide Azure Queue Storage behind typed registered queue services**, because it best aligns with the Cellix service model and gives applications a narrow, typed, intention-revealing API.
+
+### What This Means
+
+- Azure Queue Storage is exposed through **application-specific typed services**
+- Application packages define concrete queues; the framework package stays queue-agnostic
+- Application consumers use only the generated typed queue methods for the queues registered by their application
+- Raw queue transport operations remain framework-internal
+- Queue validation and queue logging are enforced by the framework on the normal typed send and receive paths
+
+### Boundary Decision
+
+#### Public to application consumers
+
+- Queue-definition authoring helpers
+- Queue registration
+- Typed send, receive, and peek methods for registered queues
+
+#### Internal to the framework
+
+- Raw Azure Queue Storage transport operations
+- Method binding and naming mechanics
+- Logging enforcement mechanics
+- Local provisioning mechanics
+
+### Environment Decision
+
+Cellix distinguishes between local development convenience and production ownership:
+
+- Local/Azurite workflows may provision known queue-related resources during startup
+- Production environments are expected to provision queues and related storage resources explicitly through infrastructure-as-code
+
+This avoids turning normal runtime queue or logging operations into hidden infrastructure mutation.
+
+## Consequences
+
+### Positive
+
+1. Applications get a narrow and intention-revealing queue API
+2. Queue payload contracts are explicit and consistently enforced
+3. Logging becomes a framework guarantee on typed queue paths
+4. The framework remains reusable across multiple application packages
+5. Local development remains practical without redefining production standards
+
+### Neutral
+
+1. Queue usage is opinionated around a registration pattern instead of ad hoc transport access
+2. Application queue definitions follow framework-provided conventions
+
+### Negative
+
+1. The framework must maintain the typed registered-service abstraction over Azure Queue Storage
+2. Consumers who need to bypass the typed queue model would require explicit framework changes
+
+## Validation
+
+Compliance with this decision is validated through:
+
+- public contract tests in `@cellix/service-queue-storage`
+- downstream package build and typecheck validation
+- alignment between framework package docs and developer guidance in the docs site
+
+## Pros and Cons of the Options
+
+### Expose a broad raw Azure Queue Storage service directly to consumers
+
+- Good, because it is simple to expose
+- Good, because it mirrors the Azure SDK closely
+- Bad, because it leaks framework internals into application code
+- Bad, because it weakens consistency around validation and logging
+- Bad, because it creates multiple competing usage styles
+
+### Hide Azure Queue Storage behind typed registered queue services
+
+- Good, because it gives applications a narrow and typed service contract
+- Good, because it centralizes framework policies for validation and logging
+- Good, because it keeps application queue definitions outside the framework package
+- Neutral, because it introduces a registration pattern
+- Bad, because it adds abstraction over the raw SDK
+
+### Use Azure Queue Storage only through Azure Functions triggers with no framework service abstraction
+
+- Good, because it follows an Azure-native trigger model
+- Good, because it can simplify some event-driven integrations
+- Bad, because it does not fit the Cellix application-service consumption model
+- Bad, because it makes typed queue APIs less consistent across applications
+- Bad, because it pushes queue policy into host-specific trigger implementations
+
+## More Information
+
+This decision complements:
+
+- [0011 Bicep](/docs/decisions/0011-bicep.md)
+- [0014 Azure Infrastructure Deployments](/docs/decisions/0014-azure-infrastructure-deployments.md)
+- [0032 Azure Blob Storage with Managed Identity & Client Uploads](/docs/decisions/0032-azure-blob-storage-client-uploads.md)
+
+Detailed developer and agent guidance belongs in the queue-storage technical overview and framework package docs rather than in this ADR.

+
+# Queue Storage Overview
+
+The `@cellix/service-queue-storage` framework package provides a typed way to use Azure Queue Storage in Cellix applications.
+
+## What It Solves
+
+Applications need to:
+
+1. Send and receive queue messages without exposing a broad raw queue transport API
+2. Define queue payload contracts clearly and validate them consistently
+3. Log queue traffic automatically on the normal application paths
+4. Support local Azurite development without redefining production infrastructure expectations
+5. Keep application-specific queue definitions out of the framework package
+
+## Architecture Pattern
+
+Cellix uses a **registered typed service** model for queues:
+
+```text
+Application Queue Definitions
+ ↓
+ registerQueues()
+ ↓
+ Application-Specific Queue Service
+ ↓
+ Typed send / receive / peek methods
+```
+
+The important boundary is:
+
+- applications define queues and use typed queue methods
+- the framework owns the raw Azure Queue Storage transport, validation, and logging enforcement
+
+## Core Capabilities
+
+### Typed Queue Definitions
+
+Applications define queue contracts explicitly, including:
+
+- queue name
+- payload schema
+- optional logging tags and metadata
+
+### Typed Queue Services
+
+Applications consume only the queue methods generated for their registered queues, not generic low-level queue methods.
+
+### Automatic Logging
+
+When logging is enabled, typed send and receive paths automatically persist queue message logs using the configured blob logger.
+
+### Local Development Support
+
+Azurite workflows may use startup-time provisioning for known queue resources, while production environments are expected to provision infrastructure explicitly.
+
+## Consumer Model
+
+The intended usage is:
+
+1. Define queues in an application package
+2. Register them once
+3. Extend the generated queue `Service`
+4. Use only the typed queue methods exposed by that application service
+
+This keeps application code focused on business queues rather than Azure transport mechanics.
+
+## Logging Model
+
+Queue logging is treated as a framework concern on the normal typed paths:
+
+- outbound messages are logged automatically when sent
+- inbound messages are logged automatically when received
+- queue definitions may contribute custom tags and metadata
+- the framework guarantees standard fields such as direction and queue name
+
+## Infrastructure Model
+
+Cellix distinguishes between local convenience and production ownership:
+
+- local development may provision known queue-related resources during startup
+- production environments should provision queues and logging storage explicitly through infrastructure-as-code

+# `@cellix/service-blob-storage`
+
+Framework Azure Blob Storage services for Cellix applications.
+
+`@cellix/service-blob-storage` exports two framework classes:
+
+- `ServiceBlobStorage`
+ - managed-identity-backed server-side blob operations only
+- `ServiceClientBlobStorage`
+ - the same server-side blob operations plus SharedKey signing for direct client uploads and downloads
+
+Use this package when application code should depend on a Cellix-owned blob abstraction instead of raw Azure SDK clients.
+
+Choose `ServiceBlobStorage` when you only need backend blob I/O.
+Choose `ServiceClientBlobStorage` when the same application also needs to sign direct client upload or download requests.
+
+## Service split
+
+`ServiceBlobStorage` is intentionally narrow:
+
+- requires `accountName`
+- optionally accepts a `TokenCredential`
+- does not accept any connection string configuration
+- provides `uploadText()`, `listBlobs()`, and `deleteBlob()`
+
+`ServiceClientBlobStorage` extends `ServiceBlobStorage`:
+
+- still uses managed identity for the Azure Blob client
+- additionally requires `signingConnectionString`
+- provides `generateReadSasToken()`
+- provides `createBlobWriteAuthorizationHeader()`
+- provides `createBlobReadAuthorizationHeader()`
+
+## Usage
+
+```ts
+import { ServiceBlobStorage, ServiceClientBlobStorage } from '@cellix/service-blob-storage';
+
+const blobStorage = new ServiceBlobStorage({
+ accountName: process.env.AZURE_STORAGE_ACCOUNT_NAME!,
+});
+
+const clientBlobStorage = new ServiceClientBlobStorage({
+ accountName: process.env.AZURE_STORAGE_ACCOUNT_NAME!,
+ signingConnectionString: process.env.AZURE_STORAGE_CONNECTION_STRING!,
+});
+
+await blobStorage.startUp();
+await clientBlobStorage.startUp();
+```
+
+Server-side blob operations:
+
+```ts
+await blobStorage.uploadText({
+ containerName: 'member-assets',
+ blobName: 'avatars/member-123.json',
+ text: '{"id":"member-123"}',
+});
+```
+
+Direct client-signing flow:
+
+```ts
+const auth = await clientBlobStorage.createBlobWriteAuthorizationHeader({
+ containerName: 'member-assets',
+ blobName: 'avatars/member-123.png',
+ contentLength: 1024,
+ contentType: 'image/png',
+});
+```
+
+## Public exports
+
+Import from the package root only:
+
+- `ServiceBlobStorage`
+- `type ServiceBlobStorageOptions`
+- `ServiceClientBlobStorage`
+- `type ServiceClientBlobStorageOptions`
+- `type BlobStorage`
+- `type ClientBlobStorage`
+- `type BlobAddress`
+- `type UploadTextBlobRequest`
+- `type ListBlobsRequest`
+- `type BlobListItem`
+- `type CreateBlobSasUrlRequest`
+- `type CreateBlobAuthorizationHeaderRequest`
+- `type BlobUploadAuthorizationHeader`
+
+## Notes
+
+- Call `startUp()` before using any blob operations.
+- Call `shutDown()` during teardown; it is idempotent.
+- Shared-key signing is isolated to `ServiceClientBlobStorage`.
+- The managed-identity base service no longer supports connection-string bootstrap behavior.
+- For local emulator scenarios, `ServiceClientBlobStorage` may use its required `signingConnectionString` to target Azurite while preserving the base service's managed-identity-only contract.

+# Cellix TDD Summary
+
+Package: `@cellix/service-blob-storage`
+
+Package path: `packages/cellix/service-blob-storage`
+
+Summary path: `packages/cellix/service-blob-storage/cellix-tdd-summary.md`
+
+## Package framing
+
+`@cellix/service-blob-storage` is an existing framework infrastructure package for Azure Blob Storage. This task is a public-contract refactor and API-surface reduction: the base service now covers only managed-identity-backed server-side blob operations, while client-signing behavior moves to a dedicated subclass.
+
+Intended consumers remain application-specific adapter packages such as `@ocom/service-blob-storage`, plus bootstrap code that registers framework services in a Cellix application.
+
+## Consumer usage exploration
+
+The key downstream consumer split is:
+
+```ts
+const blobStorage = new ServiceBlobStorage({
+ accountName: process.env.AZURE_STORAGE_ACCOUNT_NAME!,
+});
+
+const clientBlobStorage = new ServiceClientBlobStorage({
+ accountName: process.env.AZURE_STORAGE_ACCOUNT_NAME!,
+ signingConnectionString: process.env.AZURE_STORAGE_CONNECTION_STRING!,
+});
+```
+
+Consumer goals that shaped the contract:
+
+- backend blob operations should depend only on managed identity plus account name
+- client upload/download signing should be explicitly opt-in and isolated
+- application adapters should expose narrow views instead of the full framework class
+
+Failure and edge cases that shaped the contract:
+
+- `ServiceBlobStorage` must reject connection-string-style configuration at compile time
+- `ServiceClientBlobStorage` must require `signingConnectionString`
+- access before startup should still fail clearly
+- upload/list/delete behavior must remain stable on the base service
+
+## Contract gate summary
+
+Proposed public exports:
+
+- `ServiceBlobStorage`: managed-identity-only framework service for server-side blob operations
+- `ServiceClientBlobStorage`: framework subclass that adds SharedKey signing and read SAS creation
+- `BlobStorage`: base contract for upload/list/delete operations
+- `ClientBlobStorage`: extended contract for signing-capable flows
+- `BlobAddress`, `UploadTextBlobRequest`, `ListBlobsRequest`, `BlobListItem`, `CreateBlobSasUrlRequest`, `CreateBlobAuthorizationHeaderRequest`, `BlobUploadAuthorizationHeader`, `ServiceBlobStorageOptions`, `ServiceClientBlobStorageOptions`: public request/response/config contracts needed by consumers
+
+Primary success-path snippet:
+
+```ts
+const auth = await clientBlobStorage.createBlobWriteAuthorizationHeader({
+ containerName: 'member-assets',
+ blobName: 'avatars/member-123.png',
+ contentLength: 102400,
+ contentType: 'image/png',
+});
+```
+
+Human review was warranted conceptually because this is a breaking public-contract change with downstream dependents. The user explicitly requested the split and the dependent updates in the same task, so implementation proceeded with the break handled end-to-end in-repo.
+
+## Public contract
+
+Consumers should rely on these observable behaviors:
+
+- `ServiceBlobStorage.startUp()` creates a managed-identity Blob service client from `accountName`
+- `ServiceBlobStorage` exposes `uploadText()`, `listBlobs()`, and `deleteBlob()` only
+- `ServiceClientBlobStorage.startUp()` starts the same managed-identity blob client and separately enables SharedKey signing from `signingConnectionString`
+- `ServiceClientBlobStorage.generateReadSasToken()` returns a read-scoped SAS query string for a specific blob
+- `ServiceClientBlobStorage.createBlobWriteAuthorizationHeader()` returns signed write-request headers for direct client uploads
+- `ServiceClientBlobStorage.createBlobReadAuthorizationHeader()` returns signed read-request headers for direct client downloads
+
+These must remain internal:
+
+- raw Azure SDK client construction details
+- connection-string parsing mechanics
+- `StorageSharedKeyCredential` handling
+- any application-specific container naming or blob-path conventions
+
+## Test plan
+
+Public-contract tests are written through the package root entrypoint in `packages/cellix/service-blob-storage/tests/index.test.ts`.
+
+Grouped by export:
+
+- `ServiceBlobStorage`
+ - starts managed-identity blob access from the account blob endpoint
+ - uploads text with optional headers, metadata, and tags
+ - lists names and URLs with prefix filtering
+ - deletes by container and blob name
+ - guards lifecycle misuse before startup
+- `ServiceClientBlobStorage`
+ - generates read SAS tokens
+ - creates write/read authorization headers
+ - keeps the blob client on the managed-identity endpoint
+- constructor type contract
+ - `ServiceBlobStorage` rejects `signingConnectionString`
+ - `ServiceClientBlobStorage` requires `signingConnectionString`
+
+Duplicate narrower coverage was avoided by testing the public methods directly rather than re-testing internal helper parsing in isolation. The only narrower contract check added beyond runtime behavior is the constructor type-surface assertion because the new requirement is explicitly compile-time.
+
+## Changes made
+
+- Split `ServiceBlobStorage` into a managed-identity-only base class and a new `ServiceClientBlobStorage` subclass
+- Narrowed `ServiceBlobStorageOptions` to `accountName` plus optional `credential`
+- Added `ServiceClientBlobStorageOptions`
+- Split the public interfaces into `BlobStorage` and `ClientBlobStorage`
+- Removed connection-string bootstrap behavior from the base service
+- Updated `@ocom/service-blob-storage` to re-export both framework classes and keep narrow backend/client contracts
+- Updated `apps/api` bootstrap to register `ServiceBlobStorage` for backend operations and `ServiceClientBlobStorage` for client signing
+- Updated `@ocom/context-spec` descriptions to match the split registration
+
+## Documentation updates
+
+- Updated `packages/cellix/service-blob-storage/README.md`
+- Updated `packages/cellix/service-blob-storage/manifest.md`
+- Added/updated TSDoc on `ServiceBlobStorage`, `ServiceClientBlobStorage`, and their option types
+- Updated `packages/ocom/service-blob-storage/readme.md`
+- Updated this `cellix-tdd-summary.md` to reflect the new public contract
+
+## Release hardening notes
+
+- Semver impact: breaking. `ServiceBlobStorage` no longer accepts `signingConnectionString` and no longer exposes the client-signing methods.
+- Export-surface review: the root package export is intentionally limited to `ServiceBlobStorage`, `ServiceClientBlobStorage`, and the public request/response/config contracts; connection-string parsing helpers and signer internals remain private.
+- Downstream impact handled in-repo:
+ - `@ocom/service-blob-storage`
+ - `@ocom/context-spec`
+ - `apps/api`
+- Remaining release risk: `ServiceClientBlobStorage` now owns the emulator path as well as SharedKey signing. That keeps all tests passing, but it means local-emulator compatibility is intentionally scoped to the client-signing subclass rather than the managed-identity base class.
+
+## Validation performed
+
+Validated and re-ran the framework package build/test loop plus the directly affected downstream adapter and API bootstrap packages after the contract split.
+
+- Package build command:
+ `pnpm --filter @cellix/service-blob-storage build` - passed
+- Package existing test command:
+ `pnpm --filter @cellix/service-blob-storage test` - passed
+- Package integration test command:
+ `pnpm --filter @cellix/service-blob-storage test:integration` - passed
+- Additional dependent verification:

+# @cellix/service-blob-storage Manifest
+
+## Purpose
+
+`@cellix/service-blob-storage` provides reusable Azure Blob Storage infrastructure services for Cellix applications. It centralizes Azure SDK usage, lifecycle management, server-side blob operations, and optional client-signing behavior behind a small framework-owned contract.
+
+## Scope
+
+- Managed-identity startup and shutdown for server-side Azure Blob access
+- General blob operations that are stable and reusable across applications
+- Shared-key read SAS token creation and blob-scoped authorization header creation through a dedicated client-signing service
+- Container/blob addressing and request typing that stays framework-level rather than app-specific
+
+## Non-goals
+
+- Application-specific container naming rules or blob path conventions
+- GraphQL-specific response models or transport DTOs
+- Exposing raw Azure SDK clients or credentials to application code
+- Encoding OwnerCommunity-specific permissions or workflows into the framework package
+- Supporting connection-string bootstrap on the base service
+
+## Public API shape
+
+- The supported public API is the package root import: `@cellix/service-blob-storage`
+- Public exports are limited to two service classes plus framework-level request and response contracts needed by consumers and adapters
+- Azure SDK implementation details stay internal even though the package depends on `@azure/storage-blob`
+- Public request/response types are exported from the package root. Import types from the package entrypoint rather than internal file paths.
+
+## Core concepts
+
+- `ServiceBlobStorage` is a Cellix infrastructure service implementing `ServiceBase`
+- `ServiceBlobStorage` is managed-identity-only for server-side blob operations
+- `ServiceClientBlobStorage` extends `ServiceBlobStorage` and adds SharedKey signing through `signingConnectionString`
+- `ServiceClientBlobStorage` may also use that required signing connection string to target local emulator endpoints such as Azurite
+- Consumers interact with framework-defined operations such as text upload, blob deletion, blob listing, read SAS token creation, and authorization-header creation
+- Application packages should expose narrower scoped interfaces before surfacing either service through `ApiContext`
+
+## Package boundaries
+
+- This package owns Azure Blob SDK integration and client construction
+- This package owns reusable direct-upload signing behavior because it is storage-implementation-specific rather than app-specific
+- This package does not own application context exposure, container naming policies, or handler wiring
+- Downstream packages such as `@ocom/service-blob-storage` should define narrowed contracts for application code, not reimplement blob-signing behavior
+
+## Dependencies / relationships
+
+- Depends on `@cellix/api-services-spec` for Cellix infrastructure lifecycle conventions
+- Depends on `@azure/storage-blob` for Blob Storage client and SAS support
+- Intended to be wrapped by application-specific infrastructure adapter packages
+
+## Testing strategy
+
+- Validate observable behavior through the package root entrypoint only
+- Keep public-contract coverage in `tests/` so it mirrors the consumer-facing package surface
+- Mock the Azure Blob SDK so tests do not require live Azure resources
+- Cover the managed-identity base service and the client-signing subclass separately through public methods
+
+## Documentation obligations
+
+- Keep `README.md` consumer-facing and focused on the exported service contract
+- Keep TSDoc aligned with the public request and response types and both service classes
+- Update this manifest when the public surface or package boundary changes
+
+## Release-readiness standards
+
+- Public exports stay intentionally small and documented
+- Azure SDK clients and credentials do not leak through the public contract
+- Managed-identity blob operations and SharedKey signing are covered by package-scoped contract tests, including Azurite integration for the client-signing service
+- Shared-key signing remains isolated to `ServiceClientBlobStorage`

+# @cellix/service-queue-storage
+
+Type-safe Azure Queue Storage helpers for CellixJS. This package provides a small framework for defining typed queue contracts (JSON Schema), wiring producers and consumers via a typed registry, and returning registered queue services that expose only lifecycle methods plus the typed queue operations for that application. It also includes an optional `BlobQueueMessageLogger` for persisting queue payloads to blob storage.
+
+## Installation
+
+pnpm add @cellix/service-queue-storage
+
+## Quick start
+
+```typescript
+import { defineQueue, registerQueues } from '@cellix/service-queue-storage'
+
+// 1. Define your queues (typically in @ocom/service-queue-storage)
+const myQueueDef = defineQueue<{ id: string }>()(({ $payload }) => ({
+ queueName: 'my-queue',
+ schema: { type: 'object', properties: { id: { type: 'string' } }, required: ['id'] },
+ loggingTags: { source: 'my-service', messageId: $payload.id }
+}))
+
+// 2. Register queues — returns typed stubs and a bound Service base class
+const queueRegistry = registerQueues({
+ outbound: { myQueue: myQueueDef },
+ inbound: {}
+})
+
+// 3. Extend the Service base class in your application-specific package
+class MyServiceQueueStorage extends queueRegistry.Service {
+ constructor(options: { connectionString: string }) {
+ super({ connectionString: options.connectionString })
+ }
+}
+
+// 4. Create an instance and use it — queue methods are available immediately
+const svc = new MyServiceQueueStorage({ connectionString: 'UseDevelopmentStorage=true' })
+await svc.startUp()
+await svc.sendMessageToMyQueueQueue({ id: '123' })
+```
+
+## API reference
+
+- `registerQueues`: factory that accepts `outbound`/`inbound` queue maps and returns:
+ - `producer` — typed stub object (used for TypeScript type inference in consumer packages)
+ - `consumer` — typed stub object (used for TypeScript type inference in consumer packages)
+ - `Service` — a class with lifecycle methods, opt-in logging controls, and all typed queue methods wired in the constructor. Extend this class to create an application-specific queue service.
+- `defineQueue`: preferred helper for authoring typed queue definitions with `$payload.` support and no local setup boilerplate
+- `RegisteredQueueService`: public type for an application-specific queue service returned from `registerQueues()`
+- `QueueServiceLifecycle`: lifecycle contract implemented by registered queue services
+- `QueueServiceLogging`: enables or disables queue logging after construction
+- `QueueDefinition`: type describing `queueName` and message JSON Schema.
+- `QueueStorageConfig`: configuration type for constructing registered queue services.
+- `QueueMessage`: type for received queue messages (id, payload, dequeueCount, optional popReceipt).
+- `BlobQueueMessageLogger`: optional helper to persist queue payloads to blob storage.
+
+## Blob logging
+
+Logging can be enabled either in the constructor config or later through the registered service instance:
+
+```typescript
+const logger = new BlobQueueMessageLogger(blobStorage, 'queue-logs')
+const svc = new MyServiceQueueStorage({ connectionString: 'UseDevelopmentStorage=true' })
+await svc.startUp()
+svc.enableLogging(logger, { enabled: true, container: 'queue-logs' })
+```
+
+When logging is enabled, the package writes one blob per message:
+
+- Blob names are prefixed by queue direction: `inbound/` or `outbound/`
+- Blob filenames use the message timestamp in ISO UTC form, for example `2026-05-27T15:14:30.000Z.json`
+- Blob content is the message payload JSON itself, not a wrapper envelope
+- Blob tags always include `queueName`
+- Queue definitions can add custom tags and metadata, including values resolved from the message payload at runtime
+- The preferred syntax is `defineQueue()(({ $payload }) => ({ ... }))`, then use `$payload.` inside the definition callback
+- The equivalent explicit form `{ payloadField: 'communityId' }` is also supported for advanced/manual cases
+- `defineQueue()` ensures `$payload.` is checked against the keys of `MyPayload` without separate payload helper setup
+
+## Auto-provisioning
+
+When a registered queue service is started with a connection string pointing at Azurite or when `NODE_ENV=development`, it will attempt to create queues listed in the `provisionQueues` option. This is intended for local development only.

+# Package Manifest: @cellix/service-queue-storage
+
+## Purpose
+
+Type-safe Azure Queue Storage service for CellixJS — provides consistent message delivery with JSON Schema validation (Ajv), blob storage logging, and auto-provisioning in development environments.
+
+## Scope
+
+This package provides:
+- Outbound queue send operations with per-queue JSON Schema validation and encoding
+- Inbound queue receive and peek operations for consumers (dequeue and visibility)
+- Auto-provisioning of queues when running against Azurite or when NODE_ENV=development
+- Optional message logging to blob storage via a pluggable logger interface
+
+## Non-goals
+
+- Azure Functions trigger adapters (this package does not implement Function triggers)
+- Message routing, topic fanout, or cross-service message bus functionality
+- Full dead-letter queue lifecycle management
+
+## Public API shape
+
+Public exports:
+- `defineQueue()` — preferred queue-definition helper that injects a typed `$payload` proxy into a callback
+- `registerQueues({ outbound, inbound })` — factory that returns a typed registry with `producer` stubs, `consumer` stubs, and a `Service` base class
+- `RegisteredQueueService` — public type for lifecycle plus typed queue methods produced by `registerQueues`
+- `QueueServiceLifecycle` — lifecycle contract implemented by registered queue services
+- `QueueServiceLogging` — opt-in logging contract for enabling or disabling logging after construction
+- `QueueDefinition` — type describing queue name and message JSON Schema
+- `QueueStorageConfig` — configuration type for constructing registered queue services
+- `QueueMessage` — type for received queue messages
+- `BlobQueueMessageLogger` — optional helper that writes queue payloads to blob storage under `inbound/` or `outbound/` prefixes and automatically tags each blob with `queueName`
+
+## Core concepts
+
+- `QueueDefinition`: describes a queue's logical name, the JSON Schema for messages, and optional logging tags and metadata.
+- `defineQueue`: preferred authoring helper for queue definitions because it provides a typed `$payload` proxy without per-file setup noise.
+- `registerQueues`: accepts maps of outbound and inbound `QueueDefinition` objects and returns a typed registry. The registry exposes a `Service` class with lifecycle methods, opt-in logging controls, and typed queue methods already wired in the constructor — no separate bind step is required.
+- `Service` class pattern: consumer packages extend `registry.Service` to create an application-specific queue storage service. The queue bindings (producer methods, consumer methods) are applied automatically during construction via `Object.assign`. AJV validators are compiled once at `registerQueues()` call time and reused across instances.
+
+## Package boundaries
+
+This package is framework-level infrastructure. It must not contain application-specific queue names or schemas — those belong in consumer packages such as `@ocom/service-queue-storage`.
+
+## Dependencies / relationships
+
+- Depends on `@cellix/service-blob-storage` (or a blob-like adapter) for message envelope persistence when logging is enabled.
+- Consumed by `@ocom/service-queue-storage` which provides concrete queue definitions and wiring.
+
+## Testing strategy
+
+- Public behaviors are verified via vitest-cucumber feature files that run through the consumer-facing `registerQueues` factory and registered queue service class.
+- Tests must import only from the package entrypoint (the barrel) to encourage stable public contracts.
+
+## Documentation obligations
+
+- Public exports must include TSDoc with `@param`, `@returns`, and `@example` where relevant.
+- `manifest.md` and `README.md` must remain aligned with actual exported surface and usage examples.
+
+## Release-readiness standards
+
+- Internal-only exports must not be published; the barrel should be reviewed for inadvertent leakage.
+- This package is currently maintained for internal monorepo consumption and is considered pre-release. Any change to the export surface should be evaluated for semver impact and consumer compatibility.
