The fill level was one figure for the whole trip, and a trip does not have one. A motorway rapid charger is worth about 80 % because the last fifth costs as long again; the charger at the hotel is worth all of it because the car stands there all night. Between those two the difference is a whole leg, and a single setting has to be wrong about one of them. So the badge on a refuelling stop is now the way in: it shows what that stop will actually fill to, its own figure or the traveller's, and opens a panel of the six answers people actually give. Under them it says what the choice buys in kilometres, because 80 % is an abstraction and "about 290 km from here" is the thing being decided. Picking the figure a stop already has hands it back to the setting, the same gesture the kind picker uses to un-pick a kind. The value lives in places.fill_percent, beside stop_type, because it is a property of the stop rather than of the person. Null means "follow the setting", which is every stop that predates the column and every stop nobody has an opinion about, so nothing changes for a trip that never touches it. Two pieces of shared machinery came out of it rather than being copied. The popover chrome — measure before showing, flip when the window is short, close on an outside click, Escape or a scroll — is one component now, used by the kind picker and this one. So is the assembly of the range from seven settings, which the routes hook and the rail both need and which would have drifted the first time a field was added.
@trek/shared
Single source of truth for TREK's API contracts, expressed as Zod schemas and consumed by both the server (request validation + inferred DTO types) and the client (typed requests/responses).
This package is part of the incremental NestJS + React 19 migration (see the "Brownfield Rewrite" board). It is intentionally dormant until modules start importing it — adding it changes nothing for users.
Rules
- One folder per domain:
src/<domain>/<domain>.schema.ts(+.spec.ts). - Domain-agnostic building blocks live in
src/common/. - A route is only considered migrated once its contract lives here.
- Schemas are the source of truth; server DTOs and client types are inferred from them
(
z.infer<typeof schema>), never hand-duplicated.
Consumption (dev)
Both apps resolve @trek/shared to this package's TypeScript source:
- Server (
tsx): viapathsinserver/tsconfig.json. - Client (
vite): viaresolve.aliasinclient/vite.config.ts(+pathsfor the type-checker).
Production packaging (Docker / workspace wiring) is introduced in card F2, when the server first depends on this package at runtime. Until then prod builds are untouched.

The canonical error envelope is finalised in card F5 (it must match TREK's current Express error responses byte-for-byte), so it is deliberately not invented in F1.
