“We have a README.”— Olivier, Warehouse
- Reason:
- Mainly because the documentation describes a button that no longer exists. Started as Suppliers_FIXED_final_FINAL.xlsx with a script attached.
- Built by:
- Olivier, a recruiter
- Build time:
- 5 evenings
- Built with:
- Claude Code on the production branch
- Database:
- Firestore because the prototype needed to ship by Friday
- Authentication:
- the intern has production access
- Deployment:
- automatically restarted by a cron job because nobody fixed the memory leak
- Responsible:
- a Teams channel with 9 active members
- Documentation:
- a spreadsheet cell containing "ask Thomas"
- Security situation:
- security is handled by keeping the URL secret
- Future disaster:
- It will cause IT to ask "what server?".
