What changed and why

Three places where an EV plan read as more certain than it is:

• Straight-line distances. When the routing engine gives no road matrix (getMatrix fails or isn't offered), integrations/routing/ev-plan.ts falls back to greatCircleMatrix and only logged it. The plan now carries a straight-line-distances warning, and the card shows an info note: "Road distances between charging stops were unavailable, so this plan uses straight-line estimates. Charge times and arrival charge may differ."
• Member and roaming rates. When no ad-hoc tariff prices a session, the planner costs the cheapest tariff of another type, such as a profile, member or roaming rate. That price was shown as if anyone could pay it. SessionCost now reports the costed tariff's tariffType. Stops costed on a stated non-ad-hoc type carry contractTariff: true, and the card adds "member or roaming rate" beside the price. Ad-hoc and untyped tariffs are unchanged.
• Availability time. The card showed "3 of 6 available" without a time, although availability.updatedAt was already sent. It now reads "3 of 6 available as of 10:00", in the browser's locale and time zone. Without updatedAt, the old text stays.

The new response fields are optional. /directions/ev declares no response schema, so they are not dropped and the OpenAPI document is unchanged. Text is in English and German.

Verification

• New tests:

  • planner: tariffType is passed through for profile, ad-hoc and untyped tariffs;
  • adapter: the warning appears on matrix failure and not when the matrix answers; contractTariff is set for a profile tariff and absent for ad-hoc and untyped tariffs;
  • card: the availability time, the contract label and the straight-line note.

  Against the old code, the six tests for new behaviour fail; the rest pass.

• vitest run on the three affected test files: 90 passed.

• tsc --noEmit: passes for packages/core, packages/ev-charge-planner, apps/web (main and integrations configs) and apps/api (integrations config).

• Biome on the changed files and pnpm check-translations: pass (0 errors).

• scripts/check-release-information.mjs with this description: passes.

Not performed: screenshots or a browser check of the card; the maintainer asked to skip them. The full test suite is left to CI.

Release and upgrade impact

No package release: built with pnpm build from main and from this branch, @openmapx/extension-cli's dist output (cli.js plus two chunks) is identical once content-hashed chunk names and absolute module-path comments are normalized.
