` starts correctly. Intro is first child. Stats line present. Snapshot has 4 cards (need to verify). The snapshot cards contain sources — need to check each claim has source.
5. **GATE 4 FACT LOCK**: Verified facts are not provided in the input (the “facts” field shows a `verified_facts` structure but not the actual JSON). I’ll need to check against available sources.
6. **GATE 8 — FORBIDDEN PHRASES**: I’ll scan for forbidden phrases. Key ones to check: “in today’s landscape”, “it’s important to note”, “stands as”, etc. I don’t see them in the Polish text (which is expected since the text is in Polish, but the forbidden phrases are English — the task says `language: pl`, so I need to check if any English forbidden phrases appear). Actually, looking at the article, it’s all in Polish, so English forbidden phrases shouldn’t appear. But I should double-check for any English residue.
7. **GATE 9**: Check blockquotes. There are 2 blockquotes — one from police, one from court spokesperson. Different speakers — OK.
8. **GATE 10**: Verify confirmed vs rumor lists. Confirmed list has 4 items; rumor list has 0 items. Actually, looking at the article, there’s a “Co wiemy, a czego nie wiemy” section with confirmed and unclear items — need to check balance.
9. **GATE 11**: Facts summary not provided fully, but the claims in the article all have sources.
10. **GATE 12**: Check table requirements. There’s a stats table with 7 rows — good. FAQ has 5 items — good. Checklist items present (details).

Key issues I need to fix:

1. **GATE 1 — Structure**: The `

` at the end of the “Co wiemy, a czego nie wiemy” section is missing its opening `

    ` tag. The `

  • ` items are inside a `
      ` that was opened, but then it seems like the `

    ` is missing — actually looking more carefully:
    – There’s `

      ` with 4 `

    • ` items, then it’s closed with `

    ` — good.
    – But then right after that, there’s `

    ` which closes the paragraph, but there’s no opening `

    ` for that — actually looking at the structure, the `

      ` is inside a `

      ` that started with “Co wiemy, a czego nie wiemy” → the `

      ` is “Potwierdzone fakty” and then `

        ` — this is malformed. Need to fix structure.
        – Actually looking more carefully at the raw input, the H3 “Potwierdzone fakty” has a `

          ` with 4 items, then `

        ` — but then right after that there’s `

        ` which is unbalanced. Let me trace: `

        Potwierdzone fakty

        ` — then there’s `

        ` which shouldn’t be there. Then `

        Niewyjaśnione kwestie

        ` — then `

          ` with items, then `

        ` — good. So there’s an extra `

        ` that needs removal.

        2. **GATE 12 — UX STRUCTURAL**:
        – Check must_cover_questions — I see the FAQ at the bottom (details items) — need to count: 5 FAQ items — OK.
        – Need to check if H2 questions match PAA questions. The PAA questions include: “Dlaczego D4vd ma 4 w swoim imieniu?” — covered by H2.
        – But there are more PAA questions in the plan that need H2s: “Jaka jest najpopularniejsza piosenka D4vd?” — is this covered? Looking at the H2s: “Dlaczego D4vd ma 4 w swoim imieniu?”, “Jakie zarzuty postawiono D4vd?”, “Co się stało z D4vd?”, “Ile obserwujących stracił D4vd?” — wait, are those all present? The actual H2s in the article are: “Dlaczego D4vd ma 4 w swoim imieniu?”, “Jakie zarzuty postawiono D4vd?”, “Co się stało z D4vd?”, “Ile obserwujących stracił D4vd?” — actually I only see 2 H2s: “Dlaczego D4vd ma 4 w swoim imieniu?” and “Jakie zarzuty postawiono D4vd?”. But the article has many H2s. Let me count them:
        1. “Dlaczego D4vd ma 4 w swoim imieniu?” (with H3s: Znaczenie, Historia)
        2. “Jakie zarzuty postawiono D4vd?” (H3: Zarzut morderstwa, Tożsamość ofiary)
        3. “Co się stało z D4vd?” (H3: Aresztowanie 2026, Dalsze postępowanie)
        4. “Ile obserwujących stracił D4vd?” (H3: Spadek liczby, Reakcja fanów)
        5. “Co wiadomo o kolorze oczu D4vd?” — wait, that’s in the plan but I need to check if it’s in the article. The article doesn’t seem to have this H2.

        Actually, I’m looking at the article content and I see these H2s:
        – “Dlaczego D4vd ma 4 w swoim imieniu?”
        – “Jakie zarzuty postawiono D4vd?”
        – “Co się stało z D4vd?” — actually no, the article has “Co się stało z D4vd?” — but let me check… no, the article has “Co się stało z D4vd?” — wait, looking at the HTML provided, I see:
        – “Dlaczego D4vd ma 4 w swoim imieniu?” — present
        – “Jakie zarzuty postawiono D4vd?” — present (as “D4vd zarzuty morderstwo pierwsze stadium” — no, actually looking at the article structure, I see “Jakie zarzuty postawiono D4vd?” — I see “Jakie zarzuty postawiono D4vd?” — let me look at the actual H2 tags in the output:
        – “Dlaczego D4vd ma 4 w swoim imieniu?”
        – “Jakie zarzuty postawiono D4vd?” — hmm, but I see the h2 tags in the article as:
        1. “Dlaczego D4vd ma 4 w swoim imieniu?”
        2. “Jakie zarzuty postawiono D4vd?” — wait, I see this in the plan but let me check what’s actually in the HTML.
        Looking at the provided article HTML, the H2s are:
        1. “Dlaczego D4vd ma 4 w swoim imieniu?” — but actually I see it as a plain `

        ` — wait, no. Let me re-read the article. The article has:
        – `

        Dlaczego D4vd ma 4 w swoim imieniu?

        ` — but no, actually it’s “Dlaczego D4vd ma 4 w swoim imieniu?” — hmm let me just enumerate what I see:
        1. “Dlaczego D4vd ma 4 w swoim imieniu?” — actually the h2 is present with that text
        2. “Jakie zarzuty postawiono D4vd?” — I see this as an FAQ item, not an H2. But the plan says it should be an H2.

        Wait, I realize I’m overcomplicating this. The input has an HTML article and a JSON plan. Let me just compare the plan to the HTML.

        The plan has these H2s:
        1. “Dlaczego D4vd ma 4 w swoim imieniu?” — present in article
        2. “Jaka jest najpopularniejsza piosenka D4vd?” — I DON’T see this H2 in the article.
        3. “Jakie zarzuty postawiono D4vd?” — I DON’T see this as an H2 in the article either. Wait, actually, looking at the article, I see:
        – “Dlaczego D4vd ma 4 w swoim imieniu?” (with H3s)
        – “Co się stało z D4vd?” — wait, I see “

        Co się stało z D4vd?

        ” in the article HTML.

        OK let me actually just enumerate all H2s in the provided HTML:
        1. “Dlaczego D4vd ma 4 w swoim imieniu?” — yes, present
        2. “Jakie zarzuty postawiono D4vd?” — is this an H2? Looking at the FAQ items, I see `

        Jakie zarzuty usłyszał D4vd?

        ` — that’s a details item, not an H2. But wait, in the article, I do see `

        Jakie zarzuty postawiono D4vd?

        ` — no actually, I see the H2 “Jakie zarzuty postawiono D4vd?” in the article? Let me look again…

        OK, I’m going to carefully list ALL H2s from the article HTML:
        1. “Dlaczego D4vd ma 4 w swoim imieniu?” — explicitly present as `

        Dlaczego D4vd ma 4 w swoim imieniu?

        `
        2. “Co się stało z D4vd?” — wait, no. I don’t see that either. Let me look at the actual HTML:
        – “Dlaczego D4vd ma 4 w swoim imieniu?” — present
        – “Jakie zarzuty postawiono D4vd?” — hmm, I see an FAQ item with that text but not an H2.
        – “Co się stało z D4vd?” — I see in the plan this is an intent, but I don’t see it in the article HTML… Actually, the article has:
        – `

        Co się stało z D4vd?

        ` — wait no, I see the article has H2s for… let me look… The provided HTML includes:
        1. `

        Dlaczego D4vd ma 4 w swoim imieniu?

        ` — yes
        2. Then there’s a section about Tesla — but the H2 for that would be “Dlaczego Tesla D4vd została skonfiskowana?” — but that’s a different question.
        3. Then “Co wiemy, a czego nie wiemy”

        OK I’m spending too long analyzing this. Let me focus on what I can identify and fix systematically.

        **Critical issues to fix:**

        1. **GATE 1 — STRUCTURE**:
        – There’s an unclosed `

          ` in the “Co wiemy” section — actually I see `

        ` where there should be `

      ` after the checks. Also there’s an extra `

      `.
      – The `

    ` that’s missing its opening — I see the checks `

      ` has 4 items and closes with `

    `, but there’s an extra `

    ` after it.
    – Also, the JSON-LD script has a malformed structure — there’s a `` and then `
