Decisive result: **removing `sane_lists` does NOT fix it** — Python-Markdown (even by default) does not allow a list to interrupt a paragraph. So Option A is out entirely. The blank-line preprocessor (Option B) is the way. Also good news: sane_lists' mixing protection is valuable (without it, "1. c" after "- b" merges into one ugly list) — so keep sane_lists and add the preprocessor. Let me now implement `_allow_list_interruption` in research_data.py and wire it into render_markdown. Then verify: 1. Phase 2 / 5B sections render as <ul>. 2. Fenced code blocks unaffected. 3. A sanity check on a couple of other docs (e.g., a journal page) that rendering still looks right. 4. Restart server, healthcheck all routes. Implementation details: - Track fenced state with ``` / ~~~ toggles. - Insert "" before a list-marker line iff not in fence, prev line is non-blank, and prev is not itself a list/heading/table/blockquote/fence line. - Also handle Setext heading underline edge: prev line "=" or "---"? "---" would be an hr; a list after --- renders fine anyway, and inserting a blank between --- and a list is harmless. But careful: if prev is "---" it could be a setext H2 underline making the PREVIOUS text a heading — inserting a blank after it is still harmless (heading already formed). OK. Edge: what about prev being a thematic break "***"? Harmless as above. One more edge: HTML blocks (lines starting with "<")? Archive is plain md; if prev is "<div..." — inserting blank is harmless for markdown parsing (html block continues). Fine, keep guards as planned. Write the code: ```python # ------------------------------------------------------------ markdown _MATH_RE = ... _LIST_ITEM_RE = re.compile(r"^\s*([-*+] |\d+\. )") _BLOCK_START_RE = re.compile(r"^\s*(#|\||>|[-*+] |\d+\. )") def _restore_interrupted_lists(text): """Insert a blank line before a list item that directly follows a paragraph line. python-markdown (with or without sane_lists) never lets a list interrupt a paragraph: a ``- item`` line hard-wrapped right after a text line renders as literal paragraph text. The archive writes such lists (e.g. NGUYEN.md Phase 2 / 5B checklists after their note paragraphs). This pass adds the missing blank line so the list parses as a list; visible text is unchanged. Fenced code blocks are skipped. """ out, prev, in_fence = [], "", False for line in text.splitlines(): stripped = line.lstrip() if stripped.startswith(("```", "~~~")): in_fence = not in_fence elif (not in_fence and _LIST_ITEM_RE.match(line) and prev.strip() and not _BLOCK_START_RE.match(prev)): out.append("") out.append(line) prev = line return "\n".join(out) ``` Wait — the fence toggle: if the fence line itself should also count... the elif means fence lines never trigger insertion (fine) and also a fence line used as `prev` — next line inside fence: in_fence True so skip. When fence closes (``` line), in_fence toggles False; the NEXT line after closing fence: prev = "```" line → `_BLOCK_START_RE` doesn't match backticks... then a list after a closing fence would get a blank inserted — harmless (lists after fenced blocks parse fine anyway... actually do they? A list right after a fenced code block: fenced code is a block; list after it without blank line — I believe python-markdown handles that fine. Inserting a blank is a no-op then). But wait, should "```" be in _BLOCK_START_RE to prevent unnecessary blank insertions? Harmless either way — a blank line after a closing fence changes nothing. Keep simple, but add fence marker to _BLOCK_START_RE for cleanliness? It uses startswith tuple for fences... _BLOCK_START_RE is regex; add |`{3}|~{3} — meh. Simpler: in the loop, when the fence toggle triggers, we could `continue`-style handle. The current structure: fence line goes through `out.append(line); prev = line`. If prev is "```" and current line is "- item", we'd insert a blank between closing fence and list — harmless no-op. Accept. Hmm, one more: `stripped.startswith(("```", "~~~"))` — an indented fence (up to 3 spaces) is also a fence in markdown; lstrip handles that. A fence indented 4+ spaces is a code block line, not a fence — edge case, ignore (archive uses unindented fences). Apply in render_markdown before math stash: ```python protected = _MATH_RE.sub(stash, _restore_interrupted_lists(text)) ``` Then rebuild + test the NGUYEN.md Phase 2/5B sections + spot-check a journal page and D-054 (19 hits) for sanity. Also confirm verbatim-ness: rendered visible text identical (just <ul> structure). Also update the roadmap? No — render_markdown is shared; roadmap uses it. Done. Also should I log this in RH-WEBSITE.md §7 "Done" list? The file says improvement backlog with Done entries dated. This is a bug fix, but noting it in §7 Done seems consistent with how the website doc tracks changes ("2026-08-19: healthcheck...; dashboard data-freshness line..."). I'll add a Done line for 2026-08-22 including the git_log fix + this fix. RH-WEBSITE.md is one of the two paths website work may touch. Good. Then restart + healthcheck.
Decisive: **removing `sane_lists` does nothing** — Python-Markdown never lets a list interrupt a paragraph (and `sane_lists` is worth keeping: without it, mixed `-`/`1.` lists merge into one broken list). So the fix is a targeted preprocessor in `render_markdown` that inserts the missing blank line before a list that directly follows paragraph text — visible text unchanged, only block structure repaired, fenced code blocks skipped.
