# SD2026 — San Diego Trip
# Special project: Travel[95] running combined Daily+Finance mode for this trip
# Created: 07/25/26 | Corrected to yttcom.net Drive account: 07/25/26 | Two-location backup added: 07/25/26

## Trip Info
- Length: 4 days (07/25/26 - 07/28/26)
- Mode: Travel[95] tracks BOTH daily-activity-style log AND finance-style expenses for this trip
- At close: Daily Log data transfers to Daily [05], Expense data transfers to Finance [06]

## SAVE LOCATIONS — both required every session
1. Google Drive (ikre84i@yttcom.net) — systems/95-travel/SanDiego-072526-072826/
   - Live editable copies, David enters data directly here during the trip
   - Daily Log spreadsheet: https://docs.google.com/spreadsheets/d/1UROALptkHLXCU_HPXKlIZBHJE1aVNsGdPv3s8qKebc0/edit
   - Expenses spreadsheet: https://docs.google.com/spreadsheets/d/1UBo_9nfJigqlCyBgn6A2JJxbC-YXrj0PsPH-758EyGU/edit
   - Trip Notes doc: https://docs.google.com/document/d/1FO80Fd_or1whVqD1Xk3luvxON6ft6ej8Swu7T1yttX0/edit

2. Server backup — systems/95-travel/backup/SD2026/ (yttcom.net)
   - Export snapshot of the two live sheets as CSV, written here every session per D107 rotation
   - CURRENT/PREVIOUS pattern: on next export, move existing CURRENT -> PREVIOUS -> trash, write new CURRENT
   - First backup taken 07/25/26 06:56 PT

## HOW TO REPEAT THIS BACKUP (every Travel session during the trip)
1. Google Drive: download_file_content on both sheet IDs, exportMimeType=text/csv
2. Rotate existing backup: PREVIOUS -> trash, CURRENT -> PREVIOUS (per D107)
3. Write fresh CURRENT via file_write_web.php to systems/95-travel/backup/SD2026/
4. Do this at minimum once per session; more often if a lot of data was entered that session

## Transfer Plan (at trip close)
1. Pull rows from Daily Log sheet -> format as Daily[05] events -> transfer to Daily[05] inbound
2. Pull rows from Expenses sheet -> format as Finance[06] expense entries -> transfer to Finance[06] inbound
3. Trip Notes doc stays as permanent trip record, does not transfer, referenced from Travel's own knowledge/legacy files
4. Mark trip CLOSED (not pending) only if all expenses reconciled and no outstanding balances
