 # Changelog
 
+## 2025-11-25 - 2.1.1 - fix(oci)
+Preserve raw manifest bytes for digest calculation and handle string/JSON manifest bodies in OCI registry
+
+- Preserve the exact bytes of the manifest payload when computing the sha256 digest to comply with the OCI spec and avoid mismatches caused by re-serialization.
+- Accept string request bodies (converted using UTF-8) and treat already-parsed JSON objects by re-serializing as a fallback.
+- Keep existing content-type fallback logic while ensuring accurate digest calculation prior to storing manifests.
+
+## 2025-11-25 - 2.1.0 - feat(oci)
+Support configurable OCI token realm/service and centralize unauthorized responses
+
+- SmartRegistry now forwards optional ociTokens (realm and service) from auth configuration to OciRegistry when OCI is enabled
+- OciRegistry constructor accepts an optional ociTokens parameter and stores it for use in auth headers
+- Replaced repeated construction of WWW-Authenticate headers with createUnauthorizedResponse and createUnauthorizedHeadResponse helpers that use configured realm/service
+- Behavior is backwards-compatible: when ociTokens are not configured the registry falls back to the previous defaults (realm: <basePath>/v2/token, service: "registry")
+
+## 2025-11-25 - 2.0.0 - BREAKING CHANGE(pypi,rubygems)
+Revise PyPI and RubyGems handling: normalize error payloads, fix .gem parsing/packing, adjust PyPI JSON API and tests, and export smartarchive plugin
+
+- Rename error payload property from 'message' to 'error' in PyPI and RubyGems interfaces and responses; error responses are now returned as JSON objects (body: { error: ... }) instead of Buffer(JSON.stringify(...)).
+- RubyGems: treat .gem files as plain tar archives (not gzipped). Use metadata.gz and data.tar.gz correctly, switch packing helper to pack plain tar, and use zlib deflate for .rz gemspec data.
+- RubyGems registry: add legacy Marshal specs endpoint (specs.4.8.gz) and adjust versions handler invocation to accept request context.
+- PyPI: adopt PEP 691 style (files is an array of file objects) in tests and metadata; include requires_python in test package metadata; update JSON API path matching to the package-level '/{package}/json' style used by the handler.
+- Fix HTML escaping expectations in tests (requires_python values are HTML-escaped in attributes, e.g. '&gt;=3.8').
+- Export smartarchive from plugins to enable archive helpers in core modules and helpers.
+- Update tests and internal code to match the new error shape and API/format behaviour.
+
+## 2025-11-25 - 1.9.0 - feat(auth)
+Implement HMAC-SHA256 OCI JWTs; enhance PyPI & RubyGems uploads and normalize responses
+
+- AuthManager: create and validate OCI JWTs signed with HMAC-SHA256 (header.payload.signature). Signature verification, exp/nbf checks and payload decoding implemented.
+- PyPI: improved Simple API handling (PEP-691 JSON responses returned as objects), Simple HTML responses updated, upload handling enhanced to support nested/flat multipart fields, verify hashes (sha256/md5/blake2b), store files and return 201 on success.
+- RubyGems: upload flow now attempts to extract gem metadata from the .gem binary when name/version are not provided, improved validation, and upload returns 201. Added extractGemMetadata helper.
+- OCI: centralized 401 response creation (including proper WWW-Authenticate header) and HEAD behavior fixed to return no body per HTTP spec.
+- SmartRegistry: use nullish coalescing for protocol basePath defaults to avoid falsy-value bugs when basePath is an empty string.
+- Tests and helpers: test expectations adjusted (Content-Type startsWith check for HTML, PEP-691 projects is an array), test helper switched to smartarchive for packaging.
+- Package.json: added devDependency @push.rocks/smartarchive and updated dev deps.
+- Various response normalization: avoid unnecessary Buffer.from() for already-serialized objects/strings and standardize status codes for create/upload endpoints (201).
+
+## 2025-11-24 - 1.8.0 - feat(smarts3)
+Add local smarts3 testing support and documentation
+
+- Added @push.rocks/smarts3 ^5.1.0 to devDependencies to enable a local S3-compatible test server.
+- Updated README with a new "Testing with smarts3" section including a Quick Start example and integration test commands.
+- Documented benefits and CI-friendly usage for running registry integration tests locally without cloud credentials.
+
+## 2025-11-23 - 1.7.0 - feat(core)
+Standardize S3 storage config using @tsclass/tsclass IS3Descriptor and wire it into RegistryStorage and plugins exports; update README and package dependencies.
+
+- Add @tsclass/tsclass dependency to package.json to provide a standardized IS3Descriptor for S3 configuration.
+- Export tsclass from ts/plugins.ts so plugin types are available to core modules.
+- Update IStorageConfig to extend plugins.tsclass.storage.IS3Descriptor, consolidating storage configuration typing.
+- Change RegistryStorage.init() to pass the storage config directly as an IS3Descriptor to SmartBucket (bucketName remains part of IStorageConfig).
+- Update README storage section with example config and mention IS3Descriptor integration.
+
+## 2025-11-21 - 1.6.0 - feat(core)
+Add PyPI and RubyGems registries, integrate into SmartRegistry, extend storage and auth
+
+- Introduce PyPI registry implementation with PEP 503 (Simple API) and PEP 691 (JSON API), legacy upload support, content negotiation and HTML/JSON generators (ts/pypi/*).
+- Introduce RubyGems registry implementation with Compact Index support, API v1 endpoints (upload, yank/unyank), versions/names files and helpers (ts/rubygems/*).
+- Wire PyPI and RubyGems into the main orchestrator: SmartRegistry now initializes, exposes and routes requests to pypi and rubygems handlers.
+- Extend RegistryStorage with PyPI and RubyGems storage helpers (metadata, simple index, package files, compact index files, gem files).
+- Extend AuthManager to support PyPI and RubyGems UUID token creation, validation and revocation and include them in unified token validation.
+- Add verification of client-provided hashes during PyPI uploads (SHA256 always calculated and verified; MD5 and Blake2b verified when provided) to prevent corrupted uploads.
+- Export new modules from library entry point (ts/index.ts) and add lightweight rubygems index file export.
+- Add helper utilities for PyPI and RubyGems (name normalization, HTML generation, hash calculations, compact index generation/parsing).
+- Update documentation hints/readme to reflect implementation status and configuration examples for pypi and rubygems.
+
+## 2025-11-21 - 1.5.0 - feat(core)
+Add PyPI and RubyGems protocol support, Cargo token management, and storage helpers
+
+- Extend core protocol types to include 'pypi' and 'rubygems' and add protocol config entries for pypi and rubygems.
+- Add PyPI storage methods for metadata, Simple API HTML/JSON indexes, package files, version listing and deletion in RegistryStorage.
+- Add Cargo-specific storage helpers (index paths, crate storage) and ensure Cargo registry initialization and endpoints are wired into SmartRegistry.
+- Extend AuthManager with Cargo, PyPI and RubyGems token creation, validation and revocation methods; update unified validateToken to check these token types.
+- Update test helpers to create Cargo tokens and return cargoToken from registry setup.
+
+## 2025-11-21 - 1.4.1 - fix(devcontainer)
+Simplify devcontainer configuration and rename container image
+
+- Rename Dev Container name to 'gitzone.universal' and set image to mcr.microsoft.com/devcontainers/universal:4.0.1-noble
+- Remove large inline comments and example 'build'/'features' blocks to simplify the devcontainer.json
+
 ## 2025-11-21 - 1.4.0 - feat(registrystorage)
 Add deleteMavenMetadata to RegistryStorage and update Maven DELETE test to expect 204 No Content

-# Project Readme Hints
+# Project Implementation Notes
 
-This is the initial readme hints file.
+This file contains technical implementation details for PyPI and RubyGems protocols.
+
+## Python (PyPI) Protocol Implementation ✅
+
+### PEP 503: Simple Repository API (HTML-based)
+
+**URL Structure:**
+- Root: `/<base>/` - Lists all projects
+- Project: `/<base>/<project>/` - Lists all files for a project
+- All URLs MUST end with `/` (redirect if missing)
+
+**Package Name Normalization:**
+- Lowercase all characters
+- Replace runs of `.`, `-`, `_` with single `-`
+- Implementation: `re.sub(r"[-_.]+", "-", name).lower()`
+
+**HTML Format:**
+- Root: One anchor per project
+- Project: One anchor per file
+- Anchor text must match final filename
+- Anchor href links to download URL
+
+**Hash Fragments:**
+Format: `#<hashname>=<hashvalue>`
+- hashname: lowercase hash function name (recommend `sha256`)
+- hashvalue: hex-encoded digest
+
+**Data Attributes:**
+- `data-gpg-sig`: `true`/`false` for GPG signature presence
+- `data-requires-python`: PEP 345 requirement string (HTML-encode `<` as `&lt;`, `>` as `&gt;`)
+
+### PEP 691: JSON-based Simple API
+
+**Content Types:**
+- `application/vnd.pypi.simple.v1+json` - JSON format
+- `application/vnd.pypi.simple.v1+html` - HTML format
+- `text/html` - Alias for HTML (backwards compat)
+
+**Root Endpoint JSON:**
+```json
+{
+  "meta": {"api-version": "1.0"},
+  "projects": [{"name": "ProjectName"}]
+}
+```
+
+**Project Endpoint JSON:**
+```json
+{
+  "name": "normalized-name",
+  "meta": {"api-version": "1.0"},
+  "files": [
+    {
+      "filename": "package-1.0-py3-none-any.whl",
+      "url": "https://example.com/path/to/file",
+      "hashes": {"sha256": "..."},
+      "requires-python": ">=3.7",
+      "dist-info-metadata": true | {"sha256": "..."},
+      "gpg-sig": true,
+      "yanked": false | "reason string"
+    }
+  ]
+}
+```
+
+**Content Negotiation:**
+- Use `Accept` header for format selection
+- Server responds with `Content-Type` header
+- Support both JSON and HTML formats
+
+### PyPI Upload API (Legacy /legacy/)
+
+**Endpoint:**
+- URL: `https://upload.pypi.org/legacy/`
+- Method: `POST`
+- Content-Type: `multipart/form-data`
+
+**Required Form Fields:**
+- `:action` = `file_upload`
+- `protocol_version` = `1`
+- `content` = Binary file data with filename
+- `filetype` = `bdist_wheel` | `sdist`
+- `pyversion` = Python tag (e.g., `py3`, `py2.py3`) or `source` for sdist
+- `metadata_version` = Metadata standard version
+- `name` = Package name
+- `version` = Version string
+
+**Hash Digest (one required):**
+- `md5_digest`: urlsafe base64 without padding
+- `sha256_digest`: hexadecimal
+- `blake2_256_digest`: hexadecimal
+
+**Optional Fields:**
+- `attestations`: JSON array of attestation objects
+- Any Core Metadata fields (lowercase, hyphens → underscores)
+  - Example: `Description-Content-Type` → `description_content_type`
+
+**Authentication:**
+- Username/password or API token in HTTP Basic Auth
+- API tokens: username = `__token__`, password = token value
+
+**Behavior:**
+- First file uploaded creates the release
+- Multiple files uploaded sequentially for same version
+
+### PEP 694: Upload 2.0 API
+
+**Status:** Draft (not yet required, legacy API still supported)
+- Multi-step workflow with sessions
+- Async upload support with resumption
+- JSON-based API
+- Standard HTTP auth (RFC 7235)
+- Not implementing initially (legacy API sufficient)
+
+---
+
+## Ruby (RubyGems) Protocol Implementation ✅
+
+### Compact Index Format
+
+**Endpoints:**
+- `/versions` - Master list of all gems and versions
+- `/info/<RUBYGEM>` - Detailed info for specific gem
+- `/names` - Simple list of gem names
+
+**Authentication:**
+- UUID tokens similar to NPM pattern
+- API key in `Authorization` header
+- Scope format: `rubygems:gem:{name}:{read|write|yank}`
+
+### `/versions` File Format
+
+**Structure:**
+```
+created_at: 2024-04-01T00:00:05Z
+---
+RUBYGEM [-]VERSION_PLATFORM[,VERSION_PLATFORM,...] MD5
+```
+
+**Details:**
+- Metadata lines before `---` delimiter
+- One line per gem with comma-separated versions
+- `[-]` prefix indicates yanked version
+- `MD5`: Checksum of corresponding `/info/<RUBYGEM>` file
+- Append-only during month, recalculated monthly
+
+### `/info/<RUBYGEM>` File Format
+
+**Structure:**
+```
+---
+VERSION[-PLATFORM] [DEPENDENCY[,DEPENDENCY,...]]|REQUIREMENT[,REQUIREMENT,...]
+```
+
+**Dependency Format:**
+```
+GEM:CONSTRAINT[&CONSTRAINT]
+```
+- Examples: `actionmailer:= 2.2.2`, `parser:>= 3.2.2.3`
+- Operators: `=`, `>`, `<`, `>=`, `<=`, `~>`, `!=`
+- Multiple constraints: `unicode-display_width:< 3.0&>= 2.4.0`
+
+**Requirement Format:**
+```
+checksum:SHA256_HEX
+ruby:CONSTRAINT
+rubygems:CONSTRAINT
+```
+
+**Platform:**
+- Default platform is `ruby`
+- Non-default platforms: `VERSION-PLATFORM` (e.g., `3.2.1-arm64-darwin`)
+
+**Yanked Gems:**
+- Listed with `-` prefix in `/versions`
+- Excluded entirely from `/info/<RUBYGEM>` file
+
+### `/names` File Format
+
+```
+---
+gemname1
+gemname2
+gemname3
+```
+
+### HTTP Range Support
+
+**Headers:**
+- `Range: bytes=#{start}-`: Request from byte position
+- `If-None-Match`: ETag conditional request
+- `Repr-Digest`: SHA256 checksum in response
+
+**Caching Strategy:**
+1. Store file with last byte position
+2. Request range from last position
+3. Append response to existing file
+4. Verify SHA256 against `Repr-Digest`
+
+### RubyGems Upload/Management API
+
+**Upload Gem:**
+- `POST /api/v1/gems`
+- Binary `.gem` file in request body
+- `Authorization` header with API key
+
+**Yank Version:**
+- `DELETE /api/v1/gems/yank`
+- Parameters: `gem_name`, `version`
+
+**Unyank Version:**
+- `PUT /api/v1/gems/unyank`
+- Parameters: `gem_name`, `version`
+
+**Version Metadata:**
+- `GET /api/v1/versions/<gem>.json`
+- Returns JSON array of versions
+
+**Dependencies:**
+- `GET /api/v1/dependencies?gems=<comma-list>`
+- Returns dependency information for resolution
+
+---
+
+## Implementation Details
+
+### Completed Protocols
+- ✅ OCI Distribution Spec v1.1
+- ✅ NPM Registry API
+- ✅ Maven Repository
+- ✅ Cargo/crates.io Registry
+- ✅ Composer/Packagist
+- ✅ PyPI (Python Package Index) - PEP 503/691
+- ✅ RubyGems - Compact Index
+
+### Storage Paths
+
+**PyPI:**
+```
+pypi/
+├── simple/                          # PEP 503 HTML files
+│   ├── index.html                  # All packages list
+│   └── {package}/index.html        # Package versions list
+├── packages/
+│   └── {package}/{filename}        # .whl and .tar.gz files
+└── metadata/
+    └── {package}/metadata.json     # Package metadata
+```
+
+**RubyGems:**
+```
+rubygems/
+├── versions                         # Master versions file
+├── info/{gemname}                   # Per-gem info files
+├── names                            # All gem names
+└── gems/{gemname}-{version}.gem    # .gem files
+```
+
+### Authentication Pattern
+
+Both protocols should follow the existing UUID token pattern used by NPM, Maven, Cargo, Composer:
+
+```typescript
+// AuthManager additions
+createPypiToken(userId: string, readonly: boolean): string
+validatePypiToken(token: string): ITokenInfo | null
+revokePypiToken(token: string): boolean
+
+createRubyGemsToken(userId: string, readonly: boolean): string
+validateRubyGemsToken(token: string): ITokenInfo | null
+revokeRubyGemsToken(token: string): boolean
+```
+
+### Scope Format
+
+```
+pypi:package:{name}:{read|write}
+rubygems:gem:{name}:{read|write|yank}
+```
+
+### Common Patterns
+
+1. **Package name normalization** - Critical for PyPI
+2. **Checksum calculation** - SHA256 for both protocols
+3. **Append-only files** - RubyGems compact index
+4. **Content negotiation** - PyPI JSON vs HTML
+5. **Multipart upload parsing** - PyPI file uploads
+6. **Binary file handling** - Both protocols (.whl, .tar.gz, .gem)
+
+---
+
+## Key Differences from Existing Protocols
+
+**PyPI vs NPM:**
+- PyPI uses Simple API (HTML) + JSON API
+- PyPI requires package name normalization
+- PyPI uses multipart form data for uploads (not JSON)
+- PyPI supports multiple file types per release (wheel + sdist)
+
+**RubyGems vs Cargo:**
+- RubyGems uses compact index (append-only text files)
+- RubyGems uses checksums in index files (not just filenames)
+- RubyGems has HTTP Range support for incremental updates
+- RubyGems uses MD5 for index checksums, SHA256 for .gem files
+
+---
+
+## Testing Requirements
+
+### PyPI Tests Must Cover:
+- Package upload (wheel and sdist)
+- Package name normalization
+- Simple API HTML generation (PEP 503)
+- JSON API responses (PEP 691)
+- Content negotiation
+- Hash calculation and verification
+- Authentication (tokens)
+- Multi-file releases
+- Yanked packages
+
+### RubyGems Tests Must Cover:
+- Gem upload
+- Compact index generation
+- `/versions` file updates (append-only)
+- `/info/<gem>` file generation
+- `/names` file generation
+- Checksum calculations (MD5 and SHA256)
+- Platform-specific gems
+- Yanking/unyanking
+- HTTP Range requests
+- Authentication (API keys)
+
+---
+
+## Security Considerations
+
+1. **Package name validation** - Prevent path traversal
+2. **File size limits** - Prevent DoS via large uploads
+3. **Content-Type validation** - Verify file types
+4. **Checksum verification** - Ensure file integrity
+5. **Token scope enforcement** - Read vs write permissions
+6. **HTML escaping** - Prevent XSS in generated HTML
+7. **Metadata sanitization** - Clean user-provided strings
+8. **Rate limiting** - Consider upload frequency limits
+
+---
+

+    enabled: true,
+    basePath: '/rubygems',
+  },
+  auth: {
+    pypiTokens: { enabled: true },
+    rubygemsTokens: { enabled: true },
+  }
+}
+```

+## 🧪 Testing with smarts3
+
+smartregistry works seamlessly with [@push.rocks/smarts3](https://code.foss.global/push.rocks/smarts3), a local S3-compatible server for testing. This allows you to test the registry without needing cloud credentials or external services.
+
+### Quick Start with smarts3
+
+```typescript
+import { Smarts3 } from '@push.rocks/smarts3';
+import { SmartRegistry } from '@push.rocks/smartregistry';
+
+// Start local S3 server
+const s3Server = await Smarts3.createAndStart({
+  server: { port: 3456 },
+  storage: { cleanSlate: true },
+});
+
+// Manually create IS3Descriptor matching smarts3 configuration
+// Note: smarts3 v5.1.0 doesn't properly expose getS3Descriptor() yet
+const s3Descriptor = {
+  endpoint: 'localhost',
+  port: 3456,
+  accessKey: 'test',
+  accessSecret: 'test',
+  useSsl: false,
+  region: 'us-east-1',
+};
+
+// Create registry with smarts3 configuration
+const registry = new SmartRegistry({
+  storage: {
+    ...s3Descriptor,
+    bucketName: 'my-test-registry',
+  },
+  auth: {
+    jwtSecret: 'test-secret',
+    tokenStore: 'memory',
+    npmTokens: { enabled: true },
+    ociTokens: {
+      enabled: true,
+      realm: 'https://auth.example.com/token',
+      service: 'my-registry',
+    },
+  },
+  npm: { enabled: true, basePath: '/npm' },
+  oci: { enabled: true, basePath: '/oci' },
+  pypi: { enabled: true, basePath: '/pypi' },
+  cargo: { enabled: true, basePath: '/cargo' },
+});
+
+await registry.init();
+
+// Use registry...
+// Your tests here
+
+// Cleanup
+await s3Server.stop();
+```
+
+### Benefits of Testing with smarts3
+
+- ✅ **Zero Setup** - No cloud credentials or external services needed
+- ✅ **Fast** - Local filesystem storage, no network latency
+- ✅ **Isolated** - Clean slate per test run, no shared state
+- ✅ **CI/CD Ready** - Works in automated pipelines without configuration
+- ✅ **Full Compatibility** - Implements S3 API, works with IS3Descriptor
+
+### Running Integration Tests
+
+```bash
+# Run smarts3 integration test
+pnpm exec tstest test/test.integration.smarts3.node.ts --verbose
+
+# Run all tests (includes smarts3)
+pnpm test
+```
