CH-TR-204-02 / DRAFT 0.1
Wrong-spare choice, HOLD and reviewed recovery
Concept training draft — not an approved plant operating SOP
Model CHEM-P204-01 v0.1

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.

01. Confirm the task context
Action: Identify P-204 and the current concept training draft.
Check: Use the same model/version as the configuration review.
Components: P-204

02. Locate the expected part
Action: Select G-204-A as the expected coupling guard identity.
Check: The expected ID is explicit before comparing the spare.
Components: G-204-A

03. Inspect the offered spare
Action: Select G-205-B in the separate tray.
Check: The spare remains separate from the installed guard.
Components: G-205-B

04. Compare the two footprints
Action: Orbit and compare the visible feet and source identities.
Check: The offered spare has a different mounting footprint.
Components: G-204-A, G-205-B

05. Make the choice visible
Action: 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.
Components: G-205-B

06. Hold the proposed step
Action: Keep the selection on HOLD while the mismatch is unresolved.
Check: No successful-fit or completion state is awarded.
Components: G-205-B

07. Explain the mismatch
Action: Name the observed ID and footprint difference in the review record.
Check: The reason is concrete, not a generic error message.
Components: G-205-B, G-204-A

08. Request qualified review
Action: Refer the discrepancy to the task/source owner.
Check: A learner cannot self-approve a different physical part.
Components: P-204

09. Review the correct training source
Action: Compare the source-checked G-204-A identity and intended mounts.
Check: Only the reviewed training choice is eligible for recovery.
Components: G-204-A

10. Recover the training decision
Action: Select G-204-A and repeat the configuration review.
Check: The wrong spare remains in its tray; recovery is documented.
Components: G-204-A, G-205-B

11. Keep independent evidence gaps open
Action: Check whether receiving line-up evidence is supplied.
Check: Correct spare selection does not resolve missing line evidence.
Components: L-204-D

12. Record feedback for the next rehearsal
Action: Retain the choice, reason, review and recovery in the training record.
Check: The proposed lesson is reviewed before reuse.
Components: 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.
