# TODO - core-uptelligence

Upstream vendor tracking and dependency intelligence for Host UK.

**Previous review:** See `changelog/2026/jan/code-review.md` for historical context. Many issues were fixed in the 2026-01-21 wave.

## P1 - Critical / Security

### ~~Migration Mismatch - Uptime Monitoring vs Vendor Tracking~~ FIXED (P2-058)

**FIXED:** 2026-01-29

The package now clarifies that it serves dual purposes:
1. **Uptime monitoring** (existing migration 000001) - for server health tracking
2. **Vendor tracking** (new migration 000004) - for upstream dependency intelligence

**Changes made:**
- [x] Created new migration `0001_01_01_000004_create_uptelligence_vendor_tables.php` with all vendor tracking tables
- [x] Added explicit `$table` property to all models with `uptelligence_` prefix:
  - `Vendor` -> `uptelligence_vendors`
  - `VersionRelease` -> `uptelligence_version_releases`
  - `UpstreamTodo` -> `uptelligence_upstream_todos`
  - `DiffCache` -> `uptelligence_diff_cache`
  - `AnalysisLog` -> `uptelligence_analysis_logs`
  - `Asset` -> `uptelligence_assets`
  - `AssetVersion` -> `uptelligence_asset_versions`
- [x] Added appropriate indexes for common query patterns
- [x] Documented dual-purpose nature in migration comments

### ~~Webhook Signature Timing Attack Vulnerability~~ FIXED (P2-059)

**FIXED:** 2026-01-29

**Audit result:** All signature verification methods already use `hash_equals()` for timing-safe comparison. The implementation is correct.

**Changes made:**
- [x] Audited all signature verification paths - all use `hash_equals()`
- [x] Added comprehensive unit tests in `tests/Unit/WebhookSignatureVerificationTest.php`:
  - Tests for all providers (GitHub, GitLab, npm, Packagist, custom)
  - Tests for grace period/secret rotation
  - Tests for malformed signatures
  - Tests for binary payloads
  - Tests for edge cases (empty payloads, large payloads)

### ~~API Key Exposure in Logs~~ FIXED (P2-060)

**FIXED:** 2026-01-29

**Changes made:**
- [x] Added `redactSensitiveData()` method to `AIAnalyzerService`
- [x] Added `redactSensitiveData()` method to `IssueGeneratorService`
- [x] Added `redactSensitiveData()` method to `VendorUpdateCheckerService`
- [x] All Log::error calls now pass through redaction before logging
- [x] Redaction patterns cover:
  - Anthropic API keys (sk-ant-...)
  - OpenAI API keys (sk-...)
  - GitHub tokens (ghp_..., gho_..., github_pat_...)
  - Bearer tokens
  - Authorization headers
  - Generic API keys and secrets

### ~~Missing Input Validation on Webhook Payloads~~ FIXED (P2-061)

**FIXED:** 2026-01-29

**Changes made:**
- [x] Added `MAX_PAYLOAD_SIZE` constant (1 MB limit)
- [x] Added `MAX_JSON_DEPTH` constant (32 levels)
- [x] Added `validatePayloadSize()` method - rejects payloads > 1MB
- [x] Added `parseAndValidateJson()` method - validates JSON with depth limit
- [x] Added `validatePayloadStructure()` method - provider-specific validation
- [x] Added `hasExcessiveArraySize()` method - prevents DoS via large arrays
- [x] Added comprehensive unit tests in `tests/Unit/WebhookPayloadValidationTest.php`

---

## P2 - High Priority

### ~~Missing Table Name on Vendor Model~~ FIXED
**FIXED:** 2026-01-29 (as part of P2-058 migration fix)

- [x] Added explicit `protected $table = 'uptelligence_vendors';` to Vendor model
- [x] All models now have explicit table names with `uptelligence_` prefix

### DiffAnalyzerService Constructor Pattern Inconsistency
`DiffAnalyzerService` requires a `Vendor` in constructor unlike other services (which use dependency injection).

**File:** `Services/DiffAnalyzerService.php:27-33`

**Acceptance criteria:**
- [ ] Refactor to accept Vendor as method parameter instead of constructor
- [ ] Update all callers
- [ ] Register as singleton like other services

### ~~Missing Process Shell Injection Protection in AssetTrackerService~~ FIXED
~~The `AssetTrackerService` uses `Process::run()` with string interpolation.~~

**FIXED:** Now uses array-based Process invocation with package name validation.

**Changes made:**
- [x] Use array syntax for Process commands to prevent shell injection
- [x] Validate package names against allowlist pattern (Composer and NPM patterns)
- [x] Added tests for shell injection prevention in `tests/Unit/AssetTrackerServiceTest.php`

### VendorStorageService Uses Undefined File Facade
The `extractMetadata` and `getDirectorySize` methods use `File::` facade which is not imported.

**File:** `Services/VendorStorageService.php:391,417,562`

**Acceptance criteria:**
- [ ] Add `use Illuminate\Support\Facades\File;` import
- [ ] Or refactor to use Storage facade consistently

### Missing Authorisation Checks
No authorisation checks on admin Livewire components - relies entirely on route middleware.

**Files affected:**
- `View/Modal/Admin/*.php` - All admin modals

**Acceptance criteria:**
- [ ] Add explicit authorisation checks in Livewire components
- [ ] Use Gates/Policies for fine-grained access control
- [ ] Consider workspace-level permissions for multi-tenant isolation

### Missing Vendor Model Workspace Scope
The `Vendor` model doesn't use `BelongsToWorkspace` trait, but `UptelligenceDigest` does.

**File:** `Models/Vendor.php`

**Acceptance criteria:**
- [ ] Determine if vendors should be workspace-scoped or global
- [ ] If workspace-scoped, add `BelongsToWorkspace` trait
- [ ] Add `workspace_id` to migration

## P3 - Medium Priority

### TestCase Incorrect Namespace
The test case uses wrong namespace and doesn't extend Orchestra TestCase.

**File:** `tests/TestCase.php`
```php
namespace Tests;  // Should be Core\Mod\Uptelligence\Tests
```

**Acceptance criteria:**
- [ ] Fix namespace to `Core\Mod\Uptelligence\Tests`
- [ ] Extend `Orchestra\Testbench\TestCase`
- [ ] Configure package service provider loading

### Missing Test Coverage

**Acceptance criteria:**
- [ ] Add unit tests for all Services
- [ ] Add unit tests for Model methods and scopes
- [ ] Add feature tests for webhook endpoints
- [ ] Add feature tests for console commands
- [ ] Target: 80% code coverage

### Missing Rate Limiter Key Consistency
Different services use different rate limiter key formats.

**Files affected:**
- `Boot.php` - Defines limiters
- `Services/AIAnalyzerService.php:221` - Uses key without user context
- `Services/IssueGeneratorService.php:91` - Uses same global key

**Acceptance criteria:**
- [ ] Standardise rate limiter key naming
- [ ] Consider per-vendor or per-user rate limits where appropriate

### Missing Retry Logic Consistency
Some HTTP calls have retry logic, others don't.

**File:** `Services/IssueGeneratorService.php:393-406` - `createWeeklyDigest` lacks retry logic unlike `createGitHubIssue`

**Acceptance criteria:**
- [ ] Add retry logic to all external HTTP calls
- [ ] Extract common HTTP client configuration to shared method

### ~~DiffCache Table Name Hardcoded~~ FIXED
**FIXED:** 2026-01-29 (as part of P2-058 migration fix)

- [x] Renamed table to `uptelligence_diff_cache` for consistency
- [x] Updated model `$table` property
- [x] Created migration with correct table name

### Missing Carbon Import in UptelligenceDigest
Uses `\Carbon\Carbon` with full path instead of import.

**File:** `Models/UptelligenceDigest.php:258`

**Acceptance criteria:**
- [ ] Add `use Carbon\Carbon;` import
- [ ] Replace `\Carbon\Carbon` with `Carbon`

### Emoji Usage in Models
Models use emoji characters for icons which may cause encoding issues.

**Files affected:**
- `Models/Vendor.php:208-215`
- `Models/UpstreamTodo.php:215-228`
- `Models/DiffCache.php:213-250`
- `Models/AnalysisLog.php:156-170`

**Acceptance criteria:**
- [ ] Replace emojis with icon class names (Font Awesome)
- [ ] Or create separate icon mapping service
- [ ] Ensure UTF-8 encoding throughout

- Consistent, but verify across codebase

**Acceptance criteria:**
- [ ] Audit all method names for spelling consistency (prefer British)
- [ ] Document spelling conventions in CLAUDE.md

### Missing PHPDoc Return Types
Some methods lack `@return` documentation.

**Files affected:** Most service methods

**Acceptance criteria:**
