docs(adr-0004): explain why resource caps are open-time, not per-scan#69
Merged
Conversation
Add a "Why open-time, not per-scan" subsection: structural bombs (giant mmap, million-entry segment table, depth/child-count explosion) detonate during open() before a ScanOptions exists, so scan-time caps run after the damage. Enforce each cap at the earliest point the resource is consumed. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
