Subject: [PATCH] hygiene(_patterns.md): add line-leading list-marker confusion
 finding
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Promote the 'CommonMark MD032 — line-leading + / - parsed as
list marker' pattern to a named recurring-findings class in
_patterns.md after 5 instances in a single tick (2026-04-25):

- #377: '+ manifest files' continuation line
- #280: '+ provenance-aware scoring' continuation
- #195: '+ Kenji (Architect)' owner-list continuation
- #235: '+ git history' (Amara verbatim ferry)
- #219: '- [link]' (Amara verbatim ferry)

Document the two-branch fix decision tree:

- Author-controlled prose → reflow inline (replace '+'-separator
  with comma, extend prior line, etc).
- Verbatim ferry / courier content (Otto-227) → add to
  markdownlint ignore list (precedent: docs/aurora/** in #469,
  docs/amara-full-conversation/**).

Composes with Class A inline-code-span line-wrap (same shape:
line-wrap hits a CommonMark special character at line start).
Pre-commit-lint candidate noted for the doc-lint suite from
#465.

 **Future doc-lint candidate**: claim-vs-list cardinality check.
 
+### Line-leading list-marker confusion (CommonMark MD032)
+
+Observed on: #377 (`+ manifest files` continuation), #280
+(`+ provenance-aware scoring` continuation), #195 (`+ Kenji
+(Architect)` owner-list continuation), #235 + #219 (Amara
+verbatim ferry content with `+ git history` / `- [link]`
+continuation lines). 5 instances in one tick (2026-04-25).
+
+Pattern: line wrap in multi-line prose / inline-bold spans /
+multi-author lists hits a CommonMark special character (`+`,
+`-`, `*`, `1.`) at line start. Markdownlint MD032 sees the
+wrap-line as a list-item start and complains about missing
+blank-line separators. The author intent is paragraph
+continuation; the parser sees a new list.
+
+Decision tree:
+
+- **Author-controlled prose** (#377, #280, #195) — reflow
+  inline by extending the prior line, switching to
+  comma-separator (`A + B + C` → `A, B, C`), or replacing
+  `+` with `plus`. Fix the rendering, preserve the meaning.
+- **Verbatim ferry / courier content** (#235, #219) — Otto-227
+  forbids editing the verbatim text. Add the surface to the
+  markdownlint ignore list (precedent: `docs/aurora/**`,
+  `docs/amara-full-conversation/**`). Config-PR fix unblocks
+  every downstream PR touching the same surface in one shot.
+
+**Pre-commit-lint candidate**: regex check for line-leading
+`+ ` / `- ` / `* ` inside non-list contexts (paragraph
+continuation lines without preceding blank). Compose with
+the existing Class A inline-code-span line-wrap check; same
+shape (line-wrap hits a CommonMark special).
