## TL;DR
Recode the loss reason from the reason the customer stated on the final call (quoted in the notes), mapping it to the closest CRM picklist value, because the recorded reason was inferred by the summarizer from deal history instead of taken from the closing conversation and it names the wrong cause. Start with the final call transcript for the customers own stated reason for the loss, work on one affected call, record, or run first, and prove the fix there before running the full set. Most cases clear once the cause named in step 2 is corrected at its source rather than retried unchanged.

## Use this when
- You see this exact message or symptom: how to fix call summary error loss reason coded wrong from final call fails
- One run, record, call, or object is affected and you can name it
- A retry without changing anything reproduces the same result

## Not for this skill when
- The system fails with a different message and none of the signals here appear
- Nothing has failed yet and you are doing first time setup or general planning
- Every service from this vendor is down for all users, which is a vendor outage to wait out first

## Steps
1. Reproduce the failure once using the final call transcript for the customers own stated reason for the loss, and record the time, the workspace or account, and the one item it names. Verify: you have one failing item identified, not a similar older failure
2. Inspect the customers stated reason with timestamp, the picklist value written, and earlier deal notes the inference may have come from. Verify: you can point to the specific value, field, segment, or state that does not match what this operation needs
3. Apply the fix at that source: Recode the loss reason from the reason the customer stated on the final call (quoted in the notes), mapping it to the closest CRM picklist value, because the recorded reason was inferred by the summarizer from deal history instead of taken from the closing conversation and it names the wrong cause. Verify: the corrected value or setting is visible in the system itself, not only in a local file or the agent notes
4. Re-run the original operation on the single affected item first. Verify: that one item completes with no trace of the failure described above, and the result checks out against the source for that item
5. Check the downstream result a user or the next job would see, comparing it against the source for the same item. Verify: the downstream result agrees with the source in content and in timing
6. Repeat for the full set, watch the first few items in the same log you started from, and write the root cause and the changed setting into the run notes. Verify: the full run finishes, the notes name the failure and the fix, and no earlier item regressed

## Variant phrasings
### how to fix call summary error loss reason coded wrong from final call fails
The subject-first phrasing of the same failure. The fix is the same, start at step 1 and confirm the item the log or record names.
### Tool-first phrasing of this failure
The phrasing searchers use once they know which system raised it. It is the same underlying problem, not a separate bug.
### Why does this keep happening after a retry
The repeat-occurrence phrasing. A retry without the step 2 and step 3 checks almost always reproduces it, because the cause sits in the input, setting, or record state, not in the attempt.

## Why it happens
Loss reasons get guessed from stage history, no decision, no budget, when the final call often states a specific cause like a build versus buy decision. A guessed reason poisons win loss analysis for every future deal.
