Diagnosis creates hypotheses and confirmation steps. It does not authorize a repair.
Paste a 17-character VIN and decode to autofill vehicle identity.
Only codes explicitly marked Read from scan tool — verified enter diagnostic ranking, deterministic matching, or automatic DTC-focused retrieval. Typed, customer-reported, and placeholder codes remain in the job audit trail but are excluded from diagnostic evidence.
Translation preserves Customer States and builds technician wording + retrieval keywords for evidence lookup.
Optional mechanic measurements · TAG safety checks
Enter only values you physically measured or service history you verified. Blank fields are omitted — they are never treated as zero. AI/OCR values are not entered here.
TAG: not checked, no measurements entered.
Brain is a read-only mechanic aid. It never advances diagnostic authority.

Authority: READ-ONLY KNOWLEDGE
Explore common confirmed repairs, service-manual references, and published evidence without changing diagnostic state.
Confirmation Tests
Record what you physically measured or observed. Observations can change the diagnosis, but only evidence explicitly classified CONFIRMS and tied to a named fault can unlock VERIFY.
Additional findings are stored as NEUTRAL evidence by default. They can rerank the diagnosis but cannot verify a component fault.
⚠️ Unable to Complete Verification Testing? SKSK can use the symptoms, verified scan-tool DTCs, vehicle data, service information, known patterns, and all persisted evidence to determine the most likely diagnosis. This diagnosis has not been physically verified. It does not authorize a repair and does not unlock Estimate.
Explicit Verification
Current diagnostic candidate — hypothesis only —
Record a test classified CONFIRMS first.
Neutral/supporting/refuting observations never unlock Estimate. VERIFY requires a CONFIRMS test tied to the same named fault.
Verified Estimate
Locked diagnostic truth —
Pricing remains mechanic-owned. The backend consumes the persisted VERIFIED_CASE and cannot be redirected by new symptom text.
Unlocked by verification.
Customer Authorization → Work Order → Final Invoice
A verified estimate is not permission to perform or bill work. Send the persisted verified repair into the Estimate Center for explicit customer authorization. Only authorized scope can enter a Work Order, and only authorized + completed work can become the final invoice.
