# Implementation Plan: File Storage Management & UI
|
|
|
|
**Branch**: `014-file-storage-ui` | **Date**: 2026-01-24 | **Spec**: [specs/014-file-storage-ui/spec.md](../014-file-storage-ui/spec.md)
|
|
**Input**: Feature specification from `specs/014-file-storage-ui/spec.md`
|
|
|
|
## Summary
|
|
|
|
This feature implements a managed file storage system for dashboard backups and exported repositories. It introduces a configurable storage root (defaulting to outside the workspace) and a Web UI to list, upload, download, and delete files. The system enforces a structured layout with `backups/` and `repositories/` subdirectories to keep artifacts organized, while allowing flexible configuration of directory structures and filename patterns.
|
|
|
|
## Technical Context
|
|
|
|
**Language/Version**: Python 3.9+ (Backend), Node.js 18+ (Frontend)
|
|
**Primary Dependencies**: FastAPI (Backend), SvelteKit (Frontend)
|
|
**Storage**: Local Filesystem (for artifacts), Config (for storage path)
|
|
**Testing**: pytest (Backend), vitest/playwright (Frontend - implied)
|
|
**Target Platform**: Linux server
|
|
**Project Type**: Web application
|
|
**Performance Goals**: File list load < 1s for 100 files, supports 50MB+ uploads
|
|
**Constraints**: Must prevent path traversal, must not pollute git repo
|
|
**Scale/Scope**: ~2-3 backend endpoints, 1-2 frontend pages/components
|
|
|
|
## Constitution Check
|
|
|
|
*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
|
|
|
|
- **I. Semantic Protocol Compliance**:
|
|
- **Status**: PASSED
|
|
- **Check**: Will use `[DEF]` anchors and `@RELATION` tags.
|
|
- **Check**: Will follow File Structure Standard.
|
|
|
|
- **II. Causal Validity (Contracts First)**:
|
|
- **Status**: PASSED
|
|
- **Check**: Contracts will be defined in `specs/014-file-storage-ui/contracts/` before implementation.
|
|
|
|
- **III. Immutability of Architecture**:
|
|
- **Status**: PASSED
|
|
- **Check**: No changes to immutable architectural constraints expected.
|
|
|
|
- **IV. Design by Contract (DbC)**:
|
|
- **Status**: PASSED
|
|
- **Check**: Functions will define `@PRE` and `@POST` conditions.
|
|
|
|
- **V. Belief State Logging**:
|
|
- **Status**: PASSED
|
|
- **Check**: Will use standard logging patterns.
|
|
|
|
- **VI. Fractal Complexity Limit**:
|
|
- **Status**: PASSED
|
|
- **Check**: Feature scope is small, unlikely to exceed complexity limits.
|
|
|
|
- **VII. Everything is a Plugin**:
|
|
- **Status**: PASSED
|
|
- **Check**: New functionality will be implemented as a `StoragePlugin` (or similar) inheriting from `PluginBase`.
