No answer is sometimes the correct answer.

Use the reason you are blocked to choose the next evidence-gathering step. These paths do not guess a substitute model, infer a protocol from shape, or turn missing documentation into a compatibility verdict.

Recovery / Exact model is absent

Exact model is absent

The current device catalog does not contain the exact model or regional variant you need.

Next check: Search the device directory once by exact model text. If it is absent, keep the model outside the worksheet rather than substituting a similar product. Use the manufacturer manual or support page as the next primary-source target.

Recovery / Connector is still unknown

Connector is still unknown

The physical form or markings are not yet specific enough for a reliable record match.

Next check: Use connector discovery or guided identification. Keep orientation, outline and visible markings separate. If several candidates remain, do not let shape choose protocol or power behavior.

Recovery / Task is outside a desk

Task is outside a desk

The job crosses stages or does not fit a single specialized worksheet.

Next check: Return to Start and choose the closest task, or use the serial planner to represent each physical stage. Leave unsupported behavior unknown instead of forcing it into a nearby workflow.

Return to Start →

Recovery / Primary evidence is missing

Primary evidence is missing

A relevant record exists, but the exact model, range, allocation or source detail needed for the conclusion is not documented.

Next check: Open the evidence/source trail and record the missing fact as a gap. Do not complete bounds, maxima, sharing behavior or regional scope from a similar model.

Recovery / Behavior is intentionally excluded

Behavior is intentionally excluded

The application deliberately does not perform live hardware detection, automatic negotiation, repair diagnosis or hidden compatibility scoring.

Next check: Use the tool to organize documented facts and visible observations, then stop where physical testing, owner-approved guidance or a qualified technical review is required.

What recovery never does

It never substitutes a nearby model, invents a missing source value, carries private notes into another desk, diagnoses hardware, or treats an absent catalog entry as proof that a device lacks a feature.
