/plant and /plant/map import Fuel Logs CSVs by exact QR and show each
vehicle's current and previous distinct site with the dates they were
observed.
- plant_site_observations is durable, QR-keyed history. It is never wiped
and a previous site is never manufactured.
- An older or repeated snapshot must not move a vehicle backwards; untimed
conflicting sites on one day are held for review.
- A manual site change shares the same history and the same lock.
- Current/previous metadata and the sticker QR are captured BEFORE the asset
rows are deleted in the seed, so a re-seed cannot wipe them. Explicit
empty values are preserved too: clearing a site is a deliberate manual
observation, not permission to restore an old sheet value.
- Imports change location metadata only. They never touch income, cost or
fuel measurements.
- A new named site is created only for a matched Plant vehicle. Missing
coordinates mean "awaiting a pin", never a headquarters fallback.
Owner-confirmed 2026-11-04: TLB06's QR is 1089, not the old meter reading
4704. lib/plant-site-policy.json holds the confirmed aliases (Equestria
Bastion Job -> Equestria 215, Cosmo City / Lion Park -> Cosmo City); no
other identity is guessed.
Add PocketBase login, first-sign-in password changes, account settings,
and user activation, reactivation and deletion with self-removal guards.
Protect application pages and APIs and keep private pages out of PWA
caches.
Resolve plant locations from site assignments and improve map controls,
profit chart views, navigation and mobile table layouts.
Validation: production build and TypeScript passed; 28 unit tests passed.
Backend access integration tests and mobile verification are documented.
