Review CORE-000698/CORE-000704 expected results for paired PDVALMIN/PDVALMAX rules

[Y-Fukiya]

Summary

The Open Rules fixtures for CORE-000698 and CORE-000704 appear to have
paired expected-result inconsistencies. In a downstream structural comparison,
these cases are best treated as oracle/data reconciliation items rather than
native engine conformance evidence.

This is not a request to encode downstream compatibility behavior. The request
is to review whether the committed results/results.csv files match the rule
text and fixture data for the paired PDVAL minimum/maximum rules.

Observed cases

Rule	Case	Official issues	Candidate structural issues	Missing	Extra	Fingerprint
CORE-000698	negative/01	36	24	12	0	2d5714b09294d070
CORE-000698	negative/02	12	20	12	20	2c236ef4c8de4acf
CORE-000698	positive/01	0	4	0	4	ecb12e8d0d2f66e4
CORE-000704	negative/01	36	24	12	0	4580e16d2c187249
CORE-000704	negative/02	20	12	20	12	c76bfbc834a1849b
CORE-000704	positive/01	0	4	0	4	1b77302593f00a70

Review request

• Confirm whether the expected results for CORE-000698 should reference
  PDVALMIN or PDVALMAX fixture rows.
• Confirm whether the expected results for CORE-000704 should reference
  PDVALMAX or PDVALMIN fixture rows.
• Confirm whether the positive fixtures should intentionally produce issues.

Until reconciled, downstream oracle harnesses should probably keep these cases
out of supported accuracy to avoid treating a fixture/oracle discrepancy as an
engine pass or fail.

@Y-Fukiya we are in the process of reviewing the results currently but it is a large lift as we work through batches of rules. Thank you for making this, and #67 #68 #69
