luhmann lint reports false-positive dangling links for piped wiki-link syntax

[ozten]

Component: tools/luhmann/ — luhmann lint subcommand
Severity: Low (cosmetic — no incorrect data, just noise)
Impact: Across a 26-note batch, ~8 false-positive FAILs per note (≈200 total) drowned out any real lint findings. Subagents wasted tool calls verifying
each "dangling" target on disk to confirm it actually existed.

Behavior

The linter treats Obsidian-style aliased wiki-links as dangling when the target file exists.

Example: A note containing:

This relies on [[sanity-perspectives-let-one-dataset-serve-many-query-time-views|perspectives]].

…where notes/sanity-perspectives-let-one-dataset-serve-many-query-time-views.md exists on disk.

Expected: PASS — target file exists.
Actual: FAIL — "dangling wiki-link" reported for the full string sanity-perspectives-let-one-dataset-serve-many-query-time-views|perspectives.

Root cause (hypothesis)

The link-extraction regex appears to capture everything between [[ and ]] and pass that as the lookup key, rather than splitting on | first and using
only the pre-pipe portion as the filename. So [[target|display]] is looked up as target|display.md, which never exists.

Reproduction

1. In any note in the vault, write [[draft-and-published-are-document-properties-not-environment-properties-in-modern-cmses|the per-doc draft model]]
   (target exists).
2. Run luhmann lint .
3. Observe a "dangling wiki-link" FAIL listing the entire target|alias string.

Suggested fix

Where wiki-links are extracted (likely a regex like [[([^\]]+)]]), post-process the capture:

let target = capture.split('|').next().unwrap().trim();

Then resolve notes/{target}.md against the filesystem. The display alias is informational and should be ignored by the linter.

Adjacent observations

• The source: frontmatter field intentionally points to documents in inbox/ (e.g., PDFs), not to .md notes. Lint currently flags these as dangling too.
  Worth either excluding the source: field from link validation or resolving it against inbox/**/* in addition to notes/.
• The aliased-link syntax is used heavily across the existing vault — fixing this single bug likely silences the vast majority of current lint noise.

Pipeline-level workaround (already in place)

Subagents have been instructed to tolerate "dangling" FAILs that match the piped pattern after verifying the target exists. This works but is wasteful —
each subagent re-derives this every run.
