# KNOWLEDGE — Finance [06]

## Bootstrap Deploy Pattern
- write-api is at yttcom.net/write-api (root — not backend/)
- Bootstrap path requires dirname(dirname(__DIR__)) to reach public_html from backend/tmp/
- Large files (50KB+): use Python urllib — curl hits arg length limits
- system DB data-api add_decision + add_session return empty silently — use direct bootstrap SQLite writes

## Transfer Protocol
- Transfers auto-mark SEEN on first pickup — capture content immediately
- If missed: bootstrap PHP querying transfers/transfers.db SELECT * WHERE id=N
- Finance-jurisdiction transfers (Daily Life expenses) must be opened and read at pickup — not just held by subject line

## Community Inbox Deliver
- Must use POST (not GET) for deliver action

## DB Logging
- Trip expenses: log as event (trip summary) + items (line entries) in 60-sys.db
- Daily expenses: log as items with date/amount/card/merchant in detail field
- Items use action=add_item with subject/detail/status fields

## Grocery Price Tracker
- Deployed at backend/ed/grocery/Grocery_PriceTracker.html
- 4 trips / 158 records carried from v1.5

## Transfer Codes
- Community inbox / [api]: system code 06
- Transfers API: decade code 60
