# Session Start Checklist

`README.md` is the front door.

After reading `README.md`, use this checklist to start work.

## Required

1. Review `OPEN_THREADS.md`
2. Review `CONSTRAINTS.md`

## Read If Relevant

3. Review `PROJECT_CONTEXT.md` if current platform state or routing model matters
4. Review `INFRASTRUCTURE.md` if VM, IP, or host context matters
5. Review `UPSTREAMS.md` if other repos or external dependencies matter

## Deep Recovery Only

Use these only if the live working set is not enough:

- `SESSION_LOG/`
- `Session_Summaries/`
- `SCRATCH/`

## Final Check Before Working

- Confirm no drift between portal, API, and agent assumptions
- Confirm file model assumptions are accurate
- Confirm upload transport is using raw piping
- Never assume speculative features are implemented
