## TL;DR
Fix this in Notion meeting brief export by acting on the exact message first: check that the target Notion page still exists and that the integration is shared on its parent page, recreate or relink the destination if it was moved or deleted, then retry the export and confirm the prep doc opens for a recipient. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

Notion meeting brief export error "page not found" prep doc failed to share
```

## Use this when
- The operation in Notion meeting brief export fails with this exact message: Notion meeting brief export error "page not found" prep doc failed to share.
- The same failure repeats on retry with unchanged inputs.
- A call, review or send is blocked until this item completes.

## Not for this skill when
- The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
- The operation completes and you only disagree with its output. That is a quality review, not this failure.

## Steps
1. Reproduce the failure with the smallest scope that still shows it in Notion meeting brief export, and copy the full message plus the account, contact or meeting involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: check that the target Notion page still exists and that the integration is shared on its parent page, recreate or relink the destination if it was moved or deleted, then retry the export and confirm the prep doc opens for a recipient. Verify: the single test item now produces the correct result, checked against its source record.
3. Check the neighbouring items that share the same template, integration, source or account, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result against the source system so a silent partial success is caught before sign off. Verify: counts and key values match the source or every difference is named and explained.
5. Rerun the original operation in Notion meeting brief export on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

## Why it happens
Notion exports fail with page not found when the destination was moved, deleted or unshared from the integration, and the export job keeps writing to the recorded page identifier regardless.
