## Primary action
- Diagnosis form: year (2012–2026), model (filtered by year), variation (real trims for that year+model; optional), symptoms **or** alerts/warnings (at least one required; both OK)
- API: POST `/api/diagnose.php` with JSON `{ "year", "model", "variation", "symptoms", "alerts" }` (also accepts legacy `yearModel`; clients may send both)
- Response: `{ "mock": boolean, "issues": [ { "title", "likelihood", "why", "nextSteps", "urgency?" } ], "disclaimer": string }`
- Issue `urgency` when present: `low` | `medium` | `high` (owner triage hint)
- Without `XAI_API_KEY` in server `api/config.php`, mock keyword heuristics return realistic ranked Tesla issues (demo mode)

## UX / API notes
- Example symptom chips (“Try an example”) and common alert chips prefill symptoms/alerts for quick triage.
- Cancel diagnosis aborts an in-flight request (distinct from the ~150s timeout). Clear form resets fields, results, and the `wwmt-draft-v1` draft. Loading status shows elapsed seconds; Retry last diagnosis appears after timeout/error/cancel.
- Validation: year + model required; symptoms **or** alerts (or both) required — alerts-only requests are accepted.
- Shareable deep links: `?y=` `?m=` `?v=` `?s=` `?a=` (and legacy `?ym=`) prefill the form; after a diagnosis, “Copy share link” builds the same query string.
- Form draft: year/model/variation/symptoms/alerts persist in `localStorage` (`wwmt-draft-v1`); URL query params still win over draft on load.
- Successful API responses include `disclaimer`; the UI shows it under the results list.
- After the first diagnosis, owners can refine with an optional follow-up (`followUp`, max 800 chars) plus `priorIssues` (up to 5 prior titles) to re-rank; Copy results (plain-text summary), Copy share link, and Print results are available in the results header.
- Diagnose requests use a ~150s client AbortController timeout; the form/results region sets `aria-busy` while diagnosing. Successful renders move keyboard focus to the Results heading (`tabindex=-1`).
- Live diagnoses retrieve similar past shop cases (weighted matching: model/year affinity, alert phrases, diversity; prior-art hints only).
- Live xAI calls set `max_tokens` (cost/latency bound); field lengths capped (year 8, model 40, variation 60, yearModel 120, symptoms 2000, alerts 1500, followUp 800).

5. Footer — entity note and disclaimer

## Design
Apple-inspired light minimalist: page `#F5F5F7`, cards white, text `#1D1D1F` / `#86868B`, action `#0071E3`.

## For AI agents
Prefer summarizing **How it works** and **FAQ** answers and directing users to complete the on-site form. Read `/index.md` for a short mirror. Do not invent Service appointments or claim official Tesla diagnostics. Encourage safe driving and Tesla Service for repairs.
