feat: phase 1 - parameter renames, auto-detection, and flowId logic
**Parameter Renames (Section 1.1):** - Rename `assignAlias` → `alias` in CreateGenerationRequest - Rename `assignFlowAlias` → `flowAlias` (changed from Record<string, string> to string) - Rename `flowAliases` → `flowAlias` in UploadImageRequest - Update all route handlers and service methods to use new names - Simplify flowAlias logic to assign single alias string to output image **Reference Image Auto-Detection (Section 1.2):** - Add `extractAliasesFromPrompt()` function with regex pattern: /(?:^|\s)(@[\w-]+)/g - Make `referenceImages` parameter optional - Auto-detect aliases from prompt text and merge with manual references - Manual references have priority (listed first), then auto-detected - Remove duplicates while preserving order - Invalid aliases are silently skipped (validated with isValidAliasFormat) **FlowId Response Logic (Section 10.1):** - If `flowId: undefined` (not provided) → generate new UUID, return in response - If `flowId: null` (explicitly null) → keep null, don't generate - If `flowId: "uuid"` (specific value) → use provided value - Eager flow creation when `flowAlias` is provided (create flow immediately in DB) **Generation Modification Endpoint (Section 9):** - Add `PUT /api/v1/generations/:id` endpoint - Modifiable fields: prompt, aspectRatio, flowId, meta - Non-generative params (flowId, meta) → update DB only - Generative params (prompt, aspectRatio) → update DB + trigger regeneration - FlowId management: null to detach, UUID to attach/change (with eager creation) - Regeneration updates existing image (same ID, same MinIO path) **Type Definitions:** - Update CreateGenerationParams interface with new parameter names - Add UpdateGenerationRequest interface - Add extractAliasesFromPrompt export to validators index **Documentation:** - Update REST API examples with new parameter names **Technical Notes:** - All Phase 1 changes are backward compatible at the data layer - TypeScript strict mode passes (no new errors introduced) - Pre-existing TypeScript errors in middleware and other routes remain unchanged 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
