`[[page|Label]]` is Obsidian syntax, not OKF. `kb-lint` resolves it Obsidian-style — by filename, anywhere in the bundle — so it has never tripped the link gate, while every other consumer of the bundle (an OKF renderer, a Gitea wiki export, `grep` for reachability) sees bracketed text where a link should be. That is how two generated pages ended up with no inbound link at all and nobody noticed: the my-first link census of the bundle reported them as orphans because their only inbound edges were wikilinks. Mechanical conversion, 52 links across 17 pages, each resolved against the same page set `kb-lint` uses: an explicit `|Label` is kept verbatim, an unlabelled link takes the target's frontmatter `title`. Targets are emitted bundle-absolute (`/tools/niri/tips.md`), the form the spec recommends and the form 99 existing links in this bundle already use. Two links were `[[index]]`, which resolves by filename to 21 pages — the ambiguity that filename-resolution invites. Both meant their own directory's index, so both are now written out in full: `/tools/gitea/index.md`, `/tools/niri/index.md`. The linter still tolerates wikilinks; whether it should reject them outright is an open question on #64, because that would replace the two tests pinning today's tolerance. Refs #64
