EXD.4:4.3 - Change the part that prevents the next useful move
Choose the repair from the located difficulty.
| What the exchange has revealed | Construct the next contribution |
|---|---|
| A relevant term, label or signal was inaccessible | Make that same contribution accessible and check the affected point if necessary. |
| A relation is absent or cannot be followed | Supply its missing ground or intermediate correspondence, or express the same claims in a usable arrangement. Say enough to preserve the condition that matters. |
| The recipient uses a wrong relation under the same question | Show the specific mismatch, give targeted support and invite the affected inference again when the use warrants it. |
| A condition or the intended question changed | State the revised question and answer it using its own subject basis. Retain the earlier answer at its original scope. |
| A subject claim is disputed or unsupported | Inspect the relevant source or identify what the supplying practice still needs to establish. Qualify or withdraw the unsupported claim. |
| The recipient understands the grounds but disagrees with the choice | Return the preference, trade-off or decision to its owner. |
When assistance is added, preserve what was available before and after it if the later judgement depends on that distinction. Supplying a step and hearing it repeated can establish a supported response in that exchange; it does not establish later independent use.
Either participant may provide a useful repair. Check a correction against the subject basis and incorporate it when warranted. Explainer and recipient are positions in this exchange, not fixed allocations of knowledge.
