R6: forgery detection flips under an external anchor

The same coherent full-DB forgery: internal audit OPEN_UNDETECTED, external anchor audit OPEN_DETECTED; prefix truncation: undetected without a trusted head, detected with one.

Research status: STABLE the current conclusions are relatively stable
Evidence level: E2 Controlled experiment
Result: POSITIVE
Data basis: DETERMINISTIC RUNTIME A deterministic scenario executed in a real runtime; the code and procedure are listed, and the numbers are what they are.

Observed result

metrics

forgery_internal: OPEN_UNDETECTED
forgery_external: OPEN_DETECTED
truncation_without_head: OPEN_UNDETECTED
truncation_with_head: OPEN_DETECTED

Interpretation

interpretation: Detection, not prevention; and only under the stated key and head trust assumptions.

Limitations

limitations: Not a Certificate Transparency or Rekor implementation; a smaller signed hash chain with an optional head receipt.
