CH-TR-204-02 / DRAFT 0.1 / CHEM-P204-01 v0.1

Wrong-spare choice, HOLD and reviewed recovery

Concept training draft — not an approved plant operating SOP

Use only the fictional inert model. A task owner must validate source, revision, mechanics and evidence before any real-equipment lesson. This page does not authorize physical work.

  1. Confirm the task context

    Identify P-204 and the current concept training draft.

    Check Use the same model/version as the configuration review.

    P-204

  2. Locate the expected part

    Select G-204-A as the expected coupling guard identity.

    Check The expected ID is explicit before comparing the spare.

    G-204-A

  3. Inspect the offered spare

    Select G-205-B in the separate tray.

    Check The spare remains separate from the installed guard.

    G-205-B

  4. Compare the two footprints

    Orbit and compare the visible feet and source identities.

    Check The offered spare has a different mounting footprint.

    G-204-A G-205-B

  5. Make the choice visible

    Record that G-205-B is not interchangeable on the supplied concept mounts.

    Check Do not force-fit, snap or silently rename the wrong spare.

    G-205-B

  6. Hold the proposed step

    Keep the selection on HOLD while the mismatch is unresolved.

    Check No successful-fit or completion state is awarded.

    G-205-B

  7. Explain the mismatch

    Name the observed ID and footprint difference in the review record.

    Check The reason is concrete, not a generic error message.

    G-205-B G-204-A

  8. Request qualified review

    Refer the discrepancy to the task/source owner.

    Check A learner cannot self-approve a different physical part.

    P-204

  9. Review the correct training source

    Compare the source-checked G-204-A identity and intended mounts.

    Check Only the reviewed training choice is eligible for recovery.

    G-204-A

  10. Recover the training decision

    Select G-204-A and repeat the configuration review.

    Check The wrong spare remains in its tray; recovery is documented.

    G-204-A G-205-B

  11. Keep independent evidence gaps open

    Check whether receiving line-up evidence is supplied.

    Check Correct spare selection does not resolve missing line evidence.

    L-204-D

  12. Record feedback for the next rehearsal

    Retain the choice, reason, review and recovery in the training record.

    Check The proposed lesson is reviewed before reuse.

    P-204 G-204-A

Assessment

The critical gate is refusing the wrong-footprint spare. Feedback should name the mismatch, explain the HOLD and permit a source-checked retry; no operational release is scored.

Draft for review and future Genesis authoring; not a published Chemicals simulator.
