[lequangsang01]

Closes #7766

RTC wallet: RTCfe13452d122263caf633ab1876bd9631133b68b1

Changes

• Fixed KeyError crash at line 433 by replacing evidence["profile"]["multiplier"] with client.multiplier
• The evidence dict returned from submit_attestation() does not contain a multiplier key in profile

Testing

• All tests pass

This PR makes the exact same single-line change as the already-open PR #7767 — both modify vintage_miner/vintage_miner_client.py line 433 from evidence['profile']['multiplier'] to client.multiplier.

The diff is byte-for-byte identical to PR #7767:

-            print(f"Multiplier: {evidence['profile']['multiplier']}x")
+            print(f"Multiplier: {client.multiplier}x")

Merging both will either produce a merge conflict (if the branch is not rebased after #7767 merges) or result in a no-op second merge. There should only be one PR for this fix.

Recommendation: Close this PR in favor of #7767 (or vice versa), or add the issue reference (Closes #7766) to PR #7767's description if that PR was filed without it — then close this one. The fix itself (client.multiplier instead of evidence['profile']['multiplier']) is correct; it just needs to land via one PR, not two.
