Two conflicts, both from the 2026-10-19 vault compaction on main:
* frontmatter description — main shortened it to satisfy OKF DESC
(max 120 chars); this branch's longer wording would have failed the
seam. Kept main's shape and folded the new §9 in by naming
step-shape attribution instead of profiler attribution.
* the Related bullet for [[vLLM Porting and Compile Triage]] — that
page was destroyed on main, so the link is dropped rather than
resurrected; this branch's [[frank-archon]] row is kept.
Index rows regenerated with scripts/gen-vault-index.py.
