feat: Initial commit - Task Reporter incident response system

Complete implementation of the production line incident response system (生產線異常即時反應系統) including:

Backend (FastAPI):
- User authentication with AD integration and session management
- Chat room management (create, list, update, members, roles)
- Real-time messaging via WebSocket (typing indicators, reactions)
- File storage with MinIO (upload, download, image preview)

Frontend (React + Vite):
- Authentication flow with token management
- Room list with filtering, search, and pagination
- Real-time chat interface with WebSocket
- File upload with drag-and-drop and image preview
- Member management and room settings
- Breadcrumb navigation
- 53 unit tests (Vitest)

Specifications:
- authentication: AD auth, sessions, JWT tokens
- chat-room: rooms, members, templates
- realtime-messaging: WebSocket, messages, reactions
- file-storage: MinIO integration, file management
- frontend-core: React SPA structure

description: Implement an approved OpenSpec change and keep tasks in sync.
category: OpenSpec
tags: [openspec, apply]
---
<!-- OPENSPEC:START -->
**Guardrails**
- Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.
- Keep changes tightly scoped to the requested outcome.
- Refer to `openspec/AGENTS.md` (located inside the `openspec/` directory—run `ls openspec` or `openspec update` if you don't see it) if you need additional OpenSpec conventions or clarifications.
**Steps**
Track these steps as TODOs and complete them one by one.
1. Read `changes/<id>/proposal.md`, `design.md` (if present), and `tasks.md` to confirm scope and acceptance criteria.
2. Work through tasks sequentially, keeping edits minimal and focused on the requested change.
3. Confirm completion before updating statuses—make sure every item in `tasks.md` is finished.
4. Update the checklist after all work is done so each task is marked `- [x]` and reflects reality.
5. Reference `openspec list` or `openspec show <item>` when additional context is required.
**Reference**
- Use `openspec show <id> --json --deltas-only` if you need additional context from the proposal while implementing.

name: OpenSpec: Archive
description: Archive a deployed OpenSpec change and update specs.
category: OpenSpec
tags: [openspec, archive]
---
<!-- OPENSPEC:START -->
**Guardrails**
- Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.
- Keep changes tightly scoped to the requested outcome.
- Refer to `openspec/AGENTS.md` (located inside the `openspec/` directory—run `ls openspec` or `openspec update` if you don't see it) if you need additional OpenSpec conventions or clarifications.
**Steps**
1. Determine the change ID to archive:
- If this prompt already includes a specific change ID (for example inside a `<ChangeId>` block populated by slash-command arguments), use that value after trimming whitespace.
- If the conversation references a change loosely (for example by title or summary), run `openspec list` to surface likely IDs, share the relevant candidates, and confirm which one the user intends.
- Otherwise, review the conversation, run `openspec list`, and ask the user which change to archive; wait for a confirmed change ID before proceeding.
- If you still cannot identify a single change ID, stop and tell the user you cannot archive anything yet.
2. Validate the change ID by running `openspec list` (or `openspec show <id>`) and stop if the change is missing, already archived, or otherwise not ready to archive.
3. Run `openspec archive <id> --yes` so the CLI moves the change and applies spec updates without prompts (use `--skip-specs` only for tooling-only work).
4. Review the command output to confirm the target specs were updated and the change landed in `changes/archive/`.
5. Validate with `openspec validate --strict` and inspect with `openspec show <id>` if anything looks off.
**Reference**
- Use `openspec list` to confirm change IDs before archiving.
- Inspect refreshed specs with `openspec list --specs` and address any validation issues before handing off.

name: OpenSpec: Proposal
description: Scaffold a new OpenSpec change and validate strictly.
category: OpenSpec
tags: [openspec, change]
---
<!-- OPENSPEC:START -->
**Guardrails**
- Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.
- Keep changes tightly scoped to the requested outcome.
- Refer to `openspec/AGENTS.md` (located inside the `openspec/` directory—run `ls openspec` or `openspec update` if you don't see it) if you need additional OpenSpec conventions or clarifications.
- Identify any vague or ambiguous details and ask the necessary follow-up questions before editing files.
**Steps**
1. Review `openspec/project.md`, run `openspec list` and `openspec list --specs`, and inspect related code or docs (e.g., via `rg`/`ls`) to ground the proposal in current behaviour; note any gaps that require clarification.
2. Choose a unique verb-led `change-id` and scaffold `proposal.md`, `tasks.md`, and `design.md` (when needed) under `openspec/changes/<id>/`.
3. Map the change into concrete capabilities or requirements, breaking multi-scope efforts into distinct spec deltas with clear relationships and sequencing.
4. Capture architectural reasoning in `design.md` when the solution spans multiple systems, introduces new patterns, or demands trade-off discussion before committing to specs.
5. Draft spec deltas in `changes/<id>/specs/<capability>/spec.md` (one folder per capability) using `## ADDED|MODIFIED|REMOVED Requirements` with at least one `#### Scenario:` per requirement and cross-reference related capabilities when relevant.
6. Draft `tasks.md` as an ordered list of small, verifiable work items that deliver user-visible progress, include validation (tests, tooling), and highlight dependencies or parallelizable work.
7. Validate with `openspec validate <id> --strict` and resolve every issue before sharing the proposal.
**Reference**
- Use `openspec show <id> --json --deltas-only` or `openspec show <spec> --type spec` to inspect details when validation fails.
- Search existing requirements with `rg -n "Requirement:|Scenario:" openspec/specs` before writing new ones.
- Explore the codebase with `rg <keyword>`, `ls`, or direct file reads so proposals align with current implementation realities.

These instructions are for AI assistants working in this project.
Always open `@/openspec/AGENTS.md` when the request:
- Mentions planning or proposals (words like proposal, spec, change, plan)
- Introduces new capabilities, breaking changes, architecture shifts, or big performance/security work
- Sounds ambiguous and you need the authoritative spec before coding

#
# 1. Start MinIO:
# docker-compose -f docker-compose.minio.yml up -d
#
# 2. Access MinIO Console:
# Open http://localhost:9001 in your browser
# Login: minioadmin / minioadmin
#
# 3. The application will automatically create the bucket on startup
# (configured as 'task-reporter-files' in .env)
#
# 4. Stop MinIO:
# docker-compose -f docker-compose.minio.yml down
#
# 5. Remove all data:
# docker-compose -f docker-compose.minio.yml down -v
#
# ============================================================================
# Production Notes
# ============================================================================
#
# For production deployment:
# - Change MINIO_ROOT_USER and MINIO_ROOT_PASSWORD to secure values
# - Use external volume or persistent storage
# - Configure TLS/HTTPS
# - Set up proper backup policies
# - Consider MinIO distributed mode for high availability

# React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
## React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
## Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
```js
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Remove tseslint.configs.recommended and replace with this
tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
tseslint.configs.stylisticTypeChecked,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
```
You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
```js
// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
```

# OpenSpec Instructions
Instructions for AI coding assistants using OpenSpec for spec-driven development.
## TL;DR Quick Checklist
- Search existing work: `openspec spec list --long`, `openspec list` (use `rg` only for full-text search)
- Decide scope: new capability vs modify existing capability
- Pick a unique `change-id`: kebab-case, verb-led (`add-`, `update-`, `remove-`, `refactor-`)
- Scaffold: `proposal.md`, `tasks.md`, `design.md` (only if needed), and delta specs per affected capability
- Write deltas: use `## ADDED|MODIFIED|REMOVED|RENAMED Requirements`; include at least one `#### Scenario:` per requirement
- Validate: `openspec validate [change-id] --strict` and fix issues
- Request approval: Do not start implementation until proposal is approved
## Three-Stage Workflow
### Stage 1: Creating Changes
Create proposal when you need to:
- Add features or functionality
- Make breaking changes (API, schema)
- Change architecture or patterns
- Optimize performance (changes behavior)
- Update security patterns
Triggers (examples):
- "Help me create a change proposal"
- "Help me plan a change"
- "Help me create a proposal"
- "I want to create a spec proposal"
- "I want to create a spec"
Loose matching guidance:
- Contains one of: `proposal`, `change`, `spec`
- With one of: `create`, `plan`, `make`, `start`, `help`
Skip proposal for:
- Bug fixes (restore intended behavior)
- Typos, formatting, comments
- Dependency updates (non-breaking)
- Configuration changes
- Tests for existing behavior
**Workflow**
1. Review `openspec/project.md`, `openspec list`, and `openspec list --specs` to understand current context.
2. Choose a unique verb-led `change-id` and scaffold `proposal.md`, `tasks.md`, optional `design.md`, and spec deltas under `openspec/changes/<id>/`.
3. Draft spec deltas using `## ADDED|MODIFIED|REMOVED Requirements` with at least one `#### Scenario:` per requirement.
4. Run `openspec validate <id> --strict` and resolve any issues before sharing the proposal.
### Stage 2: Implementing Changes
Track these steps as TODOs and complete them one by one.
1. **Read proposal.md** - Understand what's being built
2. **Read design.md** (if exists) - Review technical decisions
3. **Read tasks.md** - Get implementation checklist
4. **Implement tasks sequentially** - Complete in order
5. **Confirm completion** - Ensure every item in `tasks.md` is finished before updating statuses
6. **Update checklist** - After all work is done, set every task to `- [x]` so the list reflects reality
7. **Approval gate** - Do not start implementation until the proposal is reviewed and approved
### Stage 3: Archiving Changes
After deployment, create separate PR to:
- Move `changes/[name]/``changes/archive/YYYY-MM-DD-[name]/`
- Update `specs/` if capabilities changed
- Use `openspec archive <change-id> --skip-specs --yes` for tooling-only changes (always pass the change ID explicitly)
- Run `openspec validate --strict` to confirm the archived change passes checks
## Before Any Task
**Context Checklist:**
- [ ] Read relevant specs in `specs/[capability]/spec.md`
- [ ] Check pending changes in `changes/` for conflicts
- [ ] Read `openspec/project.md` for conventions
- [ ] Run `openspec list` to see active changes
- [ ] Run `openspec list --specs` to see existing capabilities
**Before Creating Specs:**
- Always check if capability already exists
- Prefer modifying existing specs over creating duplicates
- Use `openspec show [spec]` to review current state
- If request is ambiguous, ask 12 clarifying questions before scaffolding
### Search Guidance
- Enumerate specs: `openspec spec list --long` (or `--json` for scripts)
- Enumerate changes: `openspec list` (or `openspec change list --json` - deprecated but available)
- Show details:
- Spec: `openspec show <spec-id> --type spec` (use `--json` for filters)
- Change: `openspec show <change-id> --json --deltas-only`
- Full-text search (use ripgrep): `rg -n "Requirement:|Scenario:" openspec/specs`
## Quick Start
### CLI Commands
```bash
# Essential commands
openspec list # List active changes
openspec list --specs # List specifications
openspec show [item] # Display change or spec
openspec validate [item] # Validate changes or specs
openspec archive <change-id> [--yes|-y] # Archive after deployment (add --yes for non-interactive runs)
# Project management
openspec init [path] # Initialize OpenSpec
openspec update [path] # Update instruction files
# Interactive mode
openspec show # Prompts for selection
openspec validate # Bulk validation mode
# Debugging
openspec show [change] --json --deltas-only
openspec validate [change] --strict
```
### Command Flags
- `--json` - Machine-readable output
- `--type change|spec` - Disambiguate items
- `--strict` - Comprehensive validation
- `--no-interactive` - Disable prompts
- `--skip-specs` - Archive without spec updates
- `--yes`/`-y` - Skip confirmation prompts (non-interactive archive)
## Directory Structure
```
openspec/
├── project.md # Project conventions
├── specs/ # Current truth - what IS built
│ └── [capability]/ # Single focused capability
│ ├── spec.md # Requirements and scenarios
│ └── design.md # Technical patterns
├── changes/ # Proposals - what SHOULD change
│ ├── [change-name]/
│ │ ├── proposal.md # Why, what, impact
│ │ ├── tasks.md # Implementation checklist

```
## Creating Change Proposals
### Decision Tree
```
New request?
├─ Bug fix restoring spec behavior? → Fix directly
├─ Typo/format/comment? → Fix directly
├─ New feature/capability? → Create proposal
├─ Breaking change? → Create proposal
├─ Architecture change? → Create proposal
└─ Unclear? → Create proposal (safer)
```
### Proposal Structure
1. **Create directory:** `changes/[change-id]/` (kebab-case, verb-led, unique)
2. **Write proposal.md:**
```markdown
# Change: [Brief description of change]
## Why
[1-2 sentences on problem/opportunity]
## What Changes
- [Bullet list of changes]
- [Mark breaking changes with **BREAKING**]
## Impact
- Affected specs: [list capabilities]
- Affected code: [key files/systems]
```
3. **Create spec deltas:** `specs/[capability]/spec.md`
```markdown
## ADDED Requirements
### Requirement: New Feature
The system SHALL provide...
#### Scenario: Success case
- **WHEN** user performs action
- **THEN** expected result
## MODIFIED Requirements
### Requirement: Existing Feature
[Complete modified requirement]
## REMOVED Requirements
### Requirement: Old Feature
**Reason**: [Why removing]
**Migration**: [How to handle]
```
If multiple capabilities are affected, create multiple delta files under `changes/[change-id]/specs/<capability>/spec.md`—one per capability.
4. **Create tasks.md:**
```markdown
## 1. Implementation
- [ ] 1.1 Create database schema
- [ ] 1.2 Implement API endpoint
- [ ] 1.3 Add frontend component
- [ ] 1.4 Write tests
```
5. **Create design.md when needed:**
Create `design.md` if any of the following apply; otherwise omit it:
- Cross-cutting change (multiple services/modules) or a new architectural pattern
- New external dependency or significant data model changes
- Security, performance, or migration complexity
- Ambiguity that benefits from technical decisions before coding
Minimal `design.md` skeleton:
```markdown
## Context
[Background, constraints, stakeholders]
## Goals / Non-Goals
- Goals: [...]
- Non-Goals: [...]
## Decisions
- Decision: [What and why]
- Alternatives considered: [Options + rationale]
## Risks / Trade-offs
- [Risk] → Mitigation
## Migration Plan
[Steps, rollback]
## Open Questions
- [...]
```
## Spec File Format
### Critical: Scenario Formatting
**CORRECT** (use #### headers):
```markdown
#### Scenario: User login success
- **WHEN** valid credentials provided
- **THEN** return JWT token
```
**WRONG** (don't use bullets or bold):
```markdown
- **Scenario: User login** ❌
**Scenario**: User login ❌
### Scenario: User login ❌
```
Every requirement MUST have at least one scenario.
### Requirement Wording
- Use SHALL/MUST for normative requirements (avoid should/may unless intentionally non-normative)
### Delta Operations
- `## ADDED Requirements` - New capabilities
- `## MODIFIED Requirements` - Changed behavior
- `## REMOVED Requirements` - Deprecated features
- `## RENAMED Requirements` - Name changes
Headers matched with `trim(header)` - whitespace ignored.
#### When to use ADDED vs MODIFIED
- ADDED: Introduces a new capability or sub-capability that can stand alone as a requirement. Prefer ADDED when the change is orthogonal (e.g., adding "Slash Command Configuration") rather than altering the semantics of an existing requirement.
- MODIFIED: Changes the behavior, scope, or acceptance criteria of an existing requirement. Always paste the full, updated requirement content (header + all scenarios). The archiver will replace the entire requirement with what you provide here; partial deltas will drop previous details.
- RENAMED: Use when only the name changes. If you also change behavior, use RENAMED (name) plus MODIFIED (content) referencing the new name.
Common pitfall: Using MODIFIED to add a new concern without including the previous text. This causes loss of detail at archive time. If you arent explicitly changing the existing requirement, add a new requirement under ADDED instead.
Authoring a MODIFIED requirement correctly:
1) Locate the existing requirement in `openspec/specs/<capability>/spec.md`.
2) Copy the entire requirement block (from `### Requirement: ...` through its scenarios).
3) Paste it under `## MODIFIED Requirements` and edit to reflect the new behavior.
4) Ensure the header text matches exactly (whitespace-insensitive) and keep at least one `#### Scenario:`.
Example for RENAMED:
```markdown
## RENAMED Requirements
- FROM: `### Requirement: Login`
- TO: `### Requirement: User Authentication`
```
## Troubleshooting
### Common Errors
**"Change must have at least one delta"**
- Check `changes/[name]/specs/` exists with .md files
- Verify files have operation prefixes (## ADDED Requirements)
**"Requirement must have at least one scenario"**
- Check scenarios use `#### Scenario:` format (4 hashtags)
- Don't use bullet points or bold for scenario headers
**Silent scenario parsing failures**
- Exact format required: `#### Scenario: Name`
- Debug with: `openspec show [change] --json --deltas-only`
### Validation Tips
```bash
# Always use strict mode for comprehensive checks
openspec validate [change] --strict
# Debug delta parsing
openspec show [change] --json | jq '.deltas'
# Check specific requirement
openspec show [spec] --json -r 1
```
## Happy Path Script
```bash
# 1) Explore current state
openspec spec list --long
openspec list
# Optional full-text search:
# rg -n "Requirement:|Scenario:" openspec/specs
# rg -n "^#|Requirement:" openspec/changes
# 2) Choose change id and scaffold
CHANGE=add-two-factor-auth
mkdir -p openspec/changes/$CHANGE/{specs/auth}
printf "## Why\n...\n\n## What Changes\n- ...\n\n## Impact\n- ...\n" > openspec/changes/$CHANGE/proposal.md
printf "## 1. Implementation\n- [ ] 1.1 ...\n" > openspec/changes/$CHANGE/tasks.md
# 3) Add deltas (example)
cat > openspec/changes/$CHANGE/specs/auth/spec.md << 'EOF'
## ADDED Requirements
### Requirement: Two-Factor Authentication
Users MUST provide a second factor during login.
#### Scenario: OTP required
- **WHEN** valid credentials are provided
- **THEN** an OTP challenge is required
EOF
# 4) Validate
openspec validate $CHANGE --strict
```
## Multi-Capability Example
```
openspec/changes/add-2fa-notify/
├── proposal.md
├── tasks.md
└── specs/
├── auth/
│ └── spec.md # ADDED: Two-Factor Authentication
└── notifications/
└── spec.md # ADDED: OTP email notification
```
auth/spec.md
```markdown
## ADDED Requirements
### Requirement: Two-Factor Authentication
...
```
notifications/spec.md
```markdown
## ADDED Requirements
### Requirement: OTP Email Notification
...
```
## Best Practices
### Simplicity First
- Default to <100 lines of new code
- Single-file implementations until proven insufficient
- Avoid frameworks without clear justification
- Choose boring, proven patterns
### Complexity Triggers
Only add complexity with:
- Performance data showing current solution too slow
- Concrete scale requirements (>1000 users, >100MB data)
- Multiple proven use cases requiring abstraction
### Clear References
- Use `file.ts:42` format for code locations
- Reference specs as `specs/auth/spec.md`
- Link related changes and PRs
### Capability Naming
- Use verb-noun: `user-auth`, `payment-capture`
- Single purpose per capability
- 10-minute understandability rule
- Split if description needs "AND"
### Change ID Naming
- Use kebab-case, short and descriptive: `add-two-factor-auth`
- Prefer verb-led prefixes: `add-`, `update-`, `remove-`, `refactor-`
- Ensure uniqueness; if taken, append `-2`, `-3`, etc.
## Tool Selection Guide
| Task | Tool | Why |
|------|------|-----|
| Find files by pattern | Glob | Fast pattern matching |
| Search code content | Grep | Optimized regex search |
| Read specific files | Read | Direct file access |
| Explore unknown scope | Task | Multi-step investigation |
## Error Recovery
### Change Conflicts
1. Run `openspec list` to see active changes
2. Check for overlapping specs
3. Coordinate with change owners
4. Consider combining proposals
### Validation Failures
1. Run with `--strict` flag
2. Check JSON output for details
3. Verify spec file format
4. Ensure scenarios properly formatted
### Missing Context
1. Read project.md first
2. Check related specs
3. Review recent archives
4. Ask for clarification
## Quick Reference
### Stage Indicators
- `changes/` - Proposed, not yet built
- `specs/` - Built and deployed
- `archive/` - Completed changes
### File Purposes
- `proposal.md` - Why and what
- `tasks.md` - Implementation steps
- `design.md` - Technical decisions
- `spec.md` - Requirements and behavior
### CLI Essentials
```bash
openspec list # What's in progress?
openspec show [item] # View details
openspec validate --strict # Is it correct?
openspec archive <change-id> [--yes|-y] # Mark complete (add --yes for automation)
```
Remember: Specs are truth. Changes are proposals. Keep them in sync.

---
## Implementation Details
### File Structure
```

├── __init__.py # Public API exports
├── models.py # UserSession SQLAlchemy model
├── schemas.py # Pydantic request/response schemas
├── router.py # Login/Logout API endpoints

```
### Database Schema
Table: `user_sessions`
- Primary key: `id` (INTEGER)
- Indexed: `internal_token` (UNIQUE), `id`
- Fields: username, display_name, internal_token, ad_token, encrypted_password, ad_token_expires_at, refresh_attempt_count, last_activity, created_at
### API Endpoints
- **POST /api/auth/login**: Authenticate with AD and create session
- **POST /api/auth/logout**: Delete session (requires Authorization header)
### Security Features
- **Encryption**: Fernet (AES-256) symmetric encryption for passwords
- **Token Separation**: Internal UUID tokens separate from AD tokens
- **Auto-Refresh**: Proactive token refresh 5 minutes before expiry
- **Retry Limit**: Max 3 consecutive auto-refresh failures before forced logout
- **Inactivity Timeout**: 72-hour (3-day) inactivity invalidation
### Configuration
Environment variables in `.env`:
```env
DATABASE_URL=sqlite:///./task_reporter.db
FERNET_KEY=lcLwCxME5_b-hvfetyya1pNSivGIVtmpehA896wfqog=
AD_API_URL=https://pj-auth-api.vercel.app/api/auth/login
SESSION_INACTIVITY_DAYS=3
TOKEN_REFRESH_THRESHOLD_MINUTES=5
MAX_REFRESH_ATTEMPTS=3
```
---
## Manual Verification
Successfully tested with actual AD credentials:
- **Username**: ymirliu@panjit.com.tw
- **Password**: 4RFV5tgb6yhn
- **Response**: `{"token": "<uuid>", "display_name": "ymirliu 劉念萱"}`
Verified behaviors:
- Login creates session with encrypted password
- Logout deletes session
- Invalid credentials return 401
- Token can be used for authenticated requests
---
## Integration Guide
Other modules can use authentication via dependency injection:
```python
from fastapi import APIRouter, Depends
from app.modules.auth import get_current_user
router = APIRouter()
@router.get("/protected-endpoint")
async def my_endpoint(current_user: dict = Depends(get_current_user)):
username = current_user["username"]
display_name = current_user["display_name"]
return {"message": f"Hello, {display_name}!"}
```
---
## Known Issues & Future Improvements
### Development Environment
- Currently using SQLite (suitable for development)
- Production deployment should migrate to PostgreSQL
### Deprecation Warnings
- `datetime.utcnow()` is deprecated in Python 3.12+
- Should migrate to `datetime.now(datetime.UTC)` in future refactor
### AuthMiddleware
- Currently commented out in `app/main.py` for testing convenience
- Should be enabled when implementing protected routes in Phase 2
---
## Next Steps
Per `Tasks.md` Phase 2:
1. Enable AuthMiddleware in main.py
2. Implement WebSocket endpoints for real-time messaging
3. Add MinIO integration for file uploads
4. Create chat room management APIs
**Recommendation**: Create next OpenSpec change proposal for one of:
- `add-chat-room-management` (聊天室 CRUD)
- `add-realtime-messaging` (WebSocket 即時通訊)
- `add-file-upload` (MinIO 檔案儲存)
