Observability

## 2026-01-29 14:30:00 | Task: PRD-003 | Phase: Research

### Context
I'm researching authentication strategies for the web app. This is critical 
because it affects security architecture and user experience.

### Inner Thoughts
The vision mentions "simple" and "quick to use". Traditional username/password 
might add friction. Considering passwordless options but need to evaluate 
complexity tradeoffs.

### Decision Point
- Considering: Traditional email/password
- Considering: Magic link (passwordless)
- Considering: OAuth only (Google/GitHub)
- **Chosen:** Magic link with OAuth fallback
- **Reason:** Aligns with "simple" goal, reduces password fatigue, 
  OAuth provides familiar alternative

### Current Progress
- [x] Read vision requirements
- [x] Research auth options
- [ ] Prototype magic link flow
- [ ] Evaluate email service options

### Observations
- Magic link requires reliable email delivery
- Need to consider rate limiting to prevent abuse
- Session duration is important for UX

### Next Action
Will research email service providers (Resend, SendGrid) and evaluate 
their free tiers since budget constraint mentioned "no paid APIs".

## 2026-01-29 10:00:00 | Task: PRD-001 | Phase: Starting

### Context
Beginning the project scaffolding PRD. This sets up the foundation for 
the entire project, so I need to be careful about initial decisions.

### Approach
1. First, review the architecture document for tech stack
2. Initialize the project with chosen tools
3. Set up basic structure
4. Configure development environment

### Potential Concerns
- Version compatibility between dependencies
- Getting the directory structure right from the start

## 2026-01-29 10:15:00 | Task: PRD-001 | Phase: Research

### Inner Thoughts
The architecture specifies Rust + Axum. I should verify I'm using the 
latest stable versions. Let me check crates.io...

### Observations
- Axum 0.7.4 is latest (released 2 weeks ago, stable)
- Tokio 1.35 is latest
- Should use workspace structure for future modularity

## 2026-01-29 10:30:00 | Task: PRD-001 | Phase: Implementation

### Decision Point
- Considering: Single crate structure
- Considering: Workspace with multiple crates
- **Chosen:** Workspace structure
- **Reason:** Project will likely grow, easier to refactor now than later

### Progress
- [x] Created Cargo.toml with workspace
- [x] Added main crate
- [ ] Add configuration
- [ ] Add basic error handling

## 2026-01-29 11:00:00 | Task: PRD-001 | Phase: Complete

### Summary
Successfully set up Rust project with Axum 0.7.4, configured workspace,
added basic structure with src/main.rs entry point.

### Key Decisions Made
- Workspace structure for scalability
- Tokio multi-threaded runtime
- Tracing for logging

### Learnings
- Axum 0.7 changed some APIs from 0.6, needed to use new Router syntax

### Files Created
- Cargo.toml
- src/main.rs
- src/lib.rs
