Phase 25 Plan 05: File Scope Promotion Summary

PATCH /files/:fileId/promote endpoint and ChatFileCard promote button with FolderUp icon wired to chatApi.promoteFile

Performance

• Duration: ~8 min
• Started: 2026-04-01T23:56:00Z
• Completed: 2026-04-01T23:59:00Z
• Tasks: 2
• Files modified: 4 + REQUIREMENTS.md

Accomplishments

• Added promoteToProject(fileId, projectId) method to chatFileService — updates projectId column via Drizzle ORM
• Added PATCH /files/:fileId/promote Express route before generic PATCH /files/:fileId to prevent shadowing
• Added promoteFile(fileId, projectId) to chatApi in ui/src/api/chat.ts with ChatFile return type
• Added promote button to ChatFileCard with FolderUp icon, optional projectId and onPromoted props, and loading state
• Marked FILE-12 Complete in REQUIREMENTS.md (checkbox + traceability table)

Task Commits

Each task was committed atomically:

1. Task 1: Add promoteToProject service method and API endpoint - c435655f (feat)
2. Task 2: Add promote button to ChatFileCard and API client method - 4c5deb4c (feat)
3. REQUIREMENTS.md update - 9a911040 (feat, in main repo)

Files Created/Modified

• server/src/services/chat-files.ts - Added promoteToProject(fileId, projectId) method
• server/src/routes/chat-files.ts - Added PATCH /files/:fileId/promote route before generic PATCH route
• ui/src/api/chat.ts - Added ChatFile import and promoteFile(fileId, projectId) method to chatApi
• ui/src/components/ChatFileCard.tsx - Added projectId?, onPromoted? props, promoting state, FolderUp button
• .planning/REQUIREMENTS.md - FILE-12 marked [x] and Complete in traceability table

Decisions Made

• Registered /files/:fileId/promote BEFORE /files/:fileId in Express router to prevent the generic catch-all from capturing promote requests
• promoteToProject returns null (not throws) when no rows returned, so the route can send an explicit 404
• Promote button only renders when all three conditions are true: file.projectId === null, projectId prop provided, onPromoted prop provided — clean opt-in pattern for callers

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

Known Stubs

None — promoteFile calls the real API endpoint. ChatFileCard renders the button conditionally based on real file.projectId field.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• FILE-12 is complete: chat-scoped files can be promoted to project scope via UI
• Callers of ChatFileCard (e.g. ChatFilePreview, ChatMessage) can now pass projectId and onPromoted to enable the promote affordance contextually
• No blockers for subsequent plans

Self-Check: PASSED

All files verified present. Commits c435655f and 4c5deb4c confirmed in git log.
