policy: remove incorrect MANDATORY_SCRIPT_VERIFY_FLAGS comment
The claim that failing mandatory script checks may trigger a DoS ban
is incorrect; Bitcoin Core does not automatically ban peers for
violating any of these flag checks.
What changed, and why it matters
This commit only removes a misleading comment in the source code. It does not change any actual code behavior. The old comment incorrectly stated that failing certain script checks could cause a peer to be banned from the network. The commit corrects that documentation-only mistake. There is no security vulnerability being fixed here.
No action needed. This is a non-functional documentation cleanup.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change deletes two lines from a comment in src/policy/policy.h. The removed text claimed that MANDATORY_SCRIPT_VERIFY_FLAGS failures ‘may trigger a DoS ban’ and directed readers to CheckInputScripts(). The commit message explicitly states this claim is incorrect and that Bitcoin Core does not auto-ban peers for these flag checks. No logic, constants, or behavior are modified.
