## VERDICT: **FIX-FIRST**

Two domains — **D7-WORSHIP** and **D6-LEADERSHIP** — carry systematic label-content false positives in their sirah_extract.json layers. The sirah extract is the foundation that feeds quran_layer, pages_trilingual.html, and the atlas. Until the extracts are re-run with accurate thematic targeting, those two domains cannot be presented as coherent. All other domains pass. Details below.

---

## CHECK 1 — VERBATIM SUBSTRING VERIFICATION (10 quotes, 4 domains)

| # | Domain | Work | Label fragment | Corpus match |
|---|--------|------|----------------|-------------|
| 1 | D2-SIRAH | ibn_ishaq | Battle of Badr — يوم بدر صبيحة الجمعة | ✅ PASS |
| 2 | D2-SIRAH | waqidi | Hudaybiyyah — عمرة الحديبية في ذي القعدة سنة ست | ✅ PASS |
| 3 | D4-FAMILY | ibn_hisham | Khadijah RA — تزويج رسول الله صلى الله عليه وسلم خديجة | ✅ PASS |
| 4 | D4-FAMILY | qadi_iyad | Fatimah RA — أطلق المحبة لفاطمة (pos 188194) | ✅ PASS (pos offset ±34 chars, text confirmed verbatim) |
| 5 | D6-LEADERSHIP | ibn_hisham | "Constitution of Madinah" — مر عامدا إلى أخته | ✅ PASS (verbatim, but label wrong — see Check 2) |
| 6 | D7-WORSHIP | ibn_hisham | Tahajjud — فيميون إذا قام من الليل يتهجد | ✅ PASS |
| 7 | D7-WORSHIP | ibn_hisham | "Fasting" mislabeled — أم حكيم البيضاء تبكي أباها | ✅ PASS (verbatim, but label wrong — see Check 2) |
| 8 | D8-LEGACY | ibn_hisham | Farewell Sermon — خطبة الوداع ثم مضى رسول الله | ✅ PASS |
| 9 | D6-LEADERSHIP | tabari | "Constitution" label — كتبها آدم عليه السلام بخطه | ✅ PASS (verbatim, but label wrong — see Check 2) |
| 10 | D5-TEACHING | ibn_hisham | Mus'ab sent to Madinah — إرسال مصعب بن عمير مع وفد العقبة | ✅ PASS |

**Verbatim gate: 10/10 quotes confirmed as substrings of their named corpus texts.**

> Method: `fragment in seerah[work]` for each snippet against the live 00-CORPUS/seerah.json (verified corpus sizes: ibn_hisham 1,425,987 chars · tabari 7,218,965 chars · ibn_kathir 10,441,844 chars · etc.).

---

## CHECK 2 — LABEL-CONTENT ACCURACY (adversarial probe of false positives)

### ❌ D7-WORSHIP: SYSTEMATIC FALSE POSITIVE CLASS — 13/21 rows affected

The extraction searched for keywords (qiyam, tahajjud, sawm, dua, istighfar, etc.) in the seerah corpus and grabbed the surrounding passage wherever the keyword appeared incidentally. Result: passages labeled as describing the Prophet's ﷺ worship practices that are in fact about unrelated subjects.

**Confirmed false positives** (corpus text read at stated pos):

| Row | Work | Label | Actual content at pos | Verdict |
|-----|------|-------|----------------------|---------|
| 2 | ibn_hisham pos 145305 | "Fasting of Muhammad ﷺ" | Lament poem by Umm Hakim al-Bayda' bint Abd al-Muttalib for her father | ❌ FALSE POSITIVE |
| 3 | ibn_hisham pos 249846 | "Fasting of Muhammad ﷺ" | Pre-Islamic battle of Bu'ath; death of Suwayd ibn Samit | ❌ FALSE POSITIVE |
| 5 | qadi_iyad pos 18731 | "Qunut supplication by Muhammad ﷺ" | Quranic verses on disbelief ("juhd"); no qunut anywhere | ❌ FALSE POSITIVE |
| 7 | ibn_sad pos 25872 | "Seeking forgiveness (istighfar) by Muhammad ﷺ" | Descendants of Seth seeking forgiveness for Adam ʿalayhi as-salam; no mention of Muhammad ﷺ | ❌ FALSE POSITIVE |
| 8 | ibn_sad pos 28811 | "Fasting of Muhammad ﷺ" | Noah's Flood — the ark, the waters, Makkah protected | ❌ FALSE POSITIVE |
| 10 | ibn_kathir pos 9140 | "Fasting of Muhammad ﷺ" | Creation of the Pen (Qalam); hadith on destiny | ❌ FALSE POSITIVE |
| 11 | ibn_kathir pos 11468 | "Seeking forgiveness by Muhammad ﷺ" | Angels bearing the throne seeking forgiveness for believers; يستغفرون in isnad context | ❌ FALSE POSITIVE |
| 13 | tabari pos 30461 | "Fasting of Muhammad ﷺ" | Creation of the Pen (Qalam) narrative | ❌ FALSE POSITIVE |
| 14 | tabari pos 31149 | "Fasting of Muhammad ﷺ" | Pen creation; hadith chain Zayd-Ubadah | ❌ FALSE POSITIVE |
| 15 | tabari pos 63159 | "Fasting observed by Muhammad ﷺ" | Night/day sequence in creation; صام يومها is incidental mention | ❌ MARGINAL (sawm present but passage is cosmological, not about the Prophet ﷺ) |
| 16 | waqidi pos 12429 | "Fasting of Muhammad ﷺ" | Hamza's first sea expedition guarding the Qurayshi caravan | ❌ FALSE POSITIVE |
| 20 | ibn_sayyid pos 112495 | "Qunut supplication by Muhammad ﷺ" | Narrator chain and Quss ibn Sa'idah anecdote | ❌ FALSE POSITIVE |
| 21 | ibn_sayyid pos 115220 | "Qunut supplication by Muhammad ﷺ" | Second Quss ibn Sa'idah anecdote; hāṭif voice | ❌ FALSE POSITIVE |

**Genuinely matching rows (8/21):** rows 1 (Tahajjud/ibn_hisham), 4 (Qunut-ish/qadi_iyad Night Vigil), 6 (istighfar/ibn_sad-Abu Talib conversion moment), 9 (du'a/ibn_kathir — clouds hadith), 12 (du'a/ibn_kathir), 17 (Fasting/waqidi — "خرج رسول الله فصام يوما أو يومين"), 18 (du'a/waqidi — Abu Sufyan battlefield), 19 (fasting/ibn_sayyid — Matan ibn's conversion with du'a).

**Impact**: The quran_layer_dataset.json and pages_trilingual.html for D7-WORSHIP inherit all 13 false-positive entries — a student reading this domain sees "Fasting of Muhammad ﷺ" sections that contain Noah's flood and pre-Islamic poetry.

---

### ❌ D6-LEADERSHIP: SYSTEMATIC FALSE POSITIVE CLASS — 6/17 rows affected

Same root cause: keyword match (صحيفة, عهد, حكم, سلم, شور, مشاور) triggered on incidental appearances.

**Confirmed false positives:**

| Row | Work | Label | Actual content at pos | Verdict |
|-----|------|-------|----------------------|---------|
| 1 | ibn_hisham pos 312986 | "Constitution of Madinah — ibn Hisham records the foundational document" | Umar's conversion: Khabbab found reading Surah Ta-Ha with Umar's sister | ❌ FALSE POSITIVE |
| 5 | tabari pos 162330 | "Constitution of Madinah — al-Tabari on the covenant Muhammad SAW wrote" | Abu Dhirr's conversation with the Prophet ﷺ about prayer and the number of prophets | ❌ FALSE POSITIVE |
| 6 | tabari pos 268809 | "Covenant with tribal leaders — al-Tabari on Muhammad SAW binding agreements" | Ibrahim ʿalayhi as-salam's childhood hidden in a cellar; Nimrod story | ❌ FALSE POSITIVE |
| 7 | tabari pos 92842 | "Prophetic judgment — al-Tabari on Muhammad SAW issuing a ruling" | Iblis stirring war among the jinn for 2,000 years; creation of Adam | ❌ FALSE POSITIVE |
| 15 | ibn_kathir pos 39860 | "Peace treaty narrative — Ibn Kathir on how Muhammad SAW conducted treaty diplomacy" | Description of oceans, rivers, and Bahr al-Masjur (the sealed sea) | ❌ FALSE POSITIVE |
| 16 | ibn_kathir pos 387935 | "Consultation before battle — Ibn Kathir on Muhammad SAW soliciting counsel" | Ibrahim ʿalayhi as-salam in the seventh heaven; prophetic covenants in the Quran | ❌ FALSE POSITIVE |

**Genuinely matching rows (11/17):** rows 2–4 (Treaty terms ibn_hisham; Judicial ruling waqidi; Treaty conclusion waqidi), 8 (Treaty of Hudaybiyyah / ibn_sad), 9–10 (Counsel in governance; Written covenant / ibn_sad), 11–14 (baladhuri entries on covenants and arbitration), 17 (Judgment narrative / ibn_kathir — clouds hadith with Prophet ﷺ present, borderline but defensible).

---

### ⚠️ D4-FAMILY: ONE FALSE POSITIVE — WRONG KHADIJAH

| Row | Work | Label | Actual content | Verdict |
|-----|------|-------|----------------|---------|
| 16 | tabari pos 933730 | "Al-Tabari on Khadijah RA, the mother of the children of the Prophet Muhammad ﷺ" | Story of al-Muttalib entering the house of **خديجة بنت سعيد بن سهم** (Khadijah bint Sa'id ibn Sahm) — a different historical woman entirely; this passage records the naming of Abd al-Muttalib | ❌ FALSE POSITIVE — wrong Khadijah |

**Impact**: Mild — one out of 20 D4-FAMILY rows misidentifies a Khadijah. The other 19 rows pass label review.

---

## CHECK 3 — TRILINGUAL PAGES RENDER REAL AYAT

✅ **PASS** — D7-WORSHIP pages_trilingual.html verified (HTML read):
- Arabic: sealed Uthmani text `قُمِ ٱلَّيْلَ إِلَّا قَلِيلًا` (73:2) — present and correct.
- English: Sahih International — "Arise [to pray] the night, except for a little -" ✅
- Urdu: Junagarhi v1.1.3 — رات (کے وقت نماز) میں کھڑے ہوجاؤ مگر کم ✅
- All three renderings are verbatim from named editions.

**Caveat**: All 21 sirah entries in D7 are assigned to 73:2 (domain central verse). This works correctly for genuinely worship-related entries but amplifies the false-positive problem: passages about Noah's flood and tribal battles are shown under 73:2 as if they are worship passages.

---

## CHECK 4 — HADITH DATASETS VERBATIM (5 IDs verified)

| ID | Corpus lookup | Status |
|----|--------------|--------|
| sunni-abudawud-427 | abudawud/427 — present | ✅ PASS |
| sunni-abudawud-499 | abudawud/499 — present | ✅ PASS |
| sunni-bukhari-3472 | bukhari/3472 — present | ✅ PASS |
| sunni-abudawud-2764 | abudawud/2764 — present | ✅ PASS |
| sunni-ibnmajah-1330 | ibnmajah/1330 — present | ✅ PASS |

> Method: `hc['hadith'][coll][num]` — correct corpus path confirmed for all 5.

**Additional check — Arabic text verbatim** for D7-WORSHIP `sunni-abudawud-765`:
The Arabic text in the layer ("حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ...") is **NOT FOUND** in any of the 7 corpus collections (abudawud, ibnmajah, bukhari, malik, muslim, nasai, tirmidhi). The text corresponds to a real and known Aisha hadith about the Prophet's ﷺ qiyam al-layl but the corpus edition does not contain this transmitter chain at this position. This is an edition/numbering discrepancy — the Arabic is authentic but unverifiable against the held corpus.

**Verdict**: 5/5 ID lookups pass; 1 Arabic text body in D7 unverifiable against held corpus (edition mismatch, not fabricated text).

---

## CHECK 5 — CLASSICAL DATASETS TRACE TO REAL CONSENSUS FILES (17:1 DISCIPLINE)

✅ **PASS** — D2-SIRAH classical_layer_dataset.json explicitly states:
```json
"adopted_from": "D2-SIRAH-CHRONOLOGY (window C4C wrote its own directory); central verse 17:1"
```
The file lives in `D2-SIRAH-CHRONOLOGY/` and the D2-SIRAH domain classical layer imports it. This is correct: the classical layer was written by the window that owns that directory, not pulled from a shared default. Verse 17:1 (the Isra verse — سُبْحَانَ الَّذِي أَسْرَى بِعَبْدِهِ) is appropriate as the central verse for the Sirah chronology domain.

**D1-NAMES-TITLES** classical layer: central verse 33:45 (يَا أَيُّهَا النَّبِيُّ إِنَّا أَرْسَلْنَاكَ شَاهِدًا) — appropriate ✅. Attesting counts sourced from 25 editions ✅.

**D7-WORSHIP** classical layer: central verse 73:2 — appropriate ✅. Agreement extracted from 23 editions ✅.

No window is borrowing another domain's classical layer without declaration.

---

## CHECK 6 — SHAMAIL LAYER (934 ROWS) CLASS SANITY

✅ **PASS** — shamail_layer.json _meta verified:

| Bucket | Count |
|--------|-------|
| manner | 647 |
| speech | 49 |
| dress | 116 |
| appearance | 122 |
| **Total kept** | **934** |
| pointers (not-shamail) | 389 |
| Partition sum asserted in-build | 1,239 (tier-1) + 1,430 (tier-2) ✅ |

**Class sanity**: The distribution is coherent for a Shamail corpus. Manner (647/934 = 69%) dominates — consistent with Tirmidhi's Shama'il, which primarily records behavioral/interaction descriptions. Dress (116) and appearance (122) are appropriately sized secondary classes. Speech (49) is the smallest, which aligns with the fact that extended verbal traditions are captured in hadith/sirah layers.

The build method correctly distinguishes "kept" (directly describes the Prophet ﷺ) from "pointer" (points to sirah content) and "other" (describes companions/events). No row with whom_unstated=0 or ghost_id=0 — the partition is clean.

---

## CHECK 7 — ATLAS COUNT RECONCILIATION

✅ **PASS** — atlas.json C4 summary verified against domain files:

| Metric | Atlas claims | Verified count | Match |
|--------|-------------|----------------|-------|
| D2-SIRAH passages | 25 | 25 (sirah_extract row_count=25 confirmed in _meta) | ✅ |
| D4-FAMILY passages | 20 | 20 (row_count confirmed) | ✅ |
| D5-TEACHING passages | 25 | 25 (row_count=25 in _meta) | ✅ |
| D6-LEADERSHIP passages | 17 | 17 (rows counted) | ✅ |
| D7-WORSHIP passages | 21 | 21 (passage_count=21 in _meta) | ✅ |
| D8-LEGACY passages | 25 | 25 (rows counted) | ✅ |
| Total sirah passages | 133 | 25+20+25+17+21+25 = 133 | ✅ |
| Shamail total | 934 | 934 (tier-1 337 + tier-2 597, sums in-build) | ✅ |
| Classical layers | 8 | 8 (D1–D9, D2 uses CHRONOLOGY sub-dir) | ✅ |
| Distinct works | 10 | 10 (all seerah.json keys confirmed in _meta) | ✅ |

---

## CHECK 8 — ADAB: PROPHET ﷺ HONORED IN EVERY AUTHORED LINE

✅ **PASS (with one minor metadata note)** —

In all domain sirah_extract.json files, every authored label uses the full honorific "Muhammad ﷺ" or "the Prophet Muhammad ﷺ". Corpus-text quotes are carried verbatim and retain classical Arabic honorifics (صلى الله عليه وسلم throughout). Allah ﷻ is correctly written with exaltation in all authored fields.

**Minor flag**: `D2-SIRAH-CHRONOLOGY/classical_layer_dataset.json` and `D2-SIRAH/classical_layer_dataset.json` both use the character **"ß"** (German Eszett) in their `_meta.adab` field and within authored label strings (e.g., "The Prophet ß was born..."). This is a character-rendering substitution in the author's system that produced the files. The character "ß" is not the ﷺ glyph. This affects:
- All 12 `CL-XX` label strings in the classical_layer_dataset.json for D2-SIRAH
- The `_meta.adab` description string

The display-facing content (pages_trilingual.html, education_pack.json) in D2-SIRAH does not appear to carry this issue — the "ß" is confined to the classical layer JSON _meta and label authored text. **FIX recommended**: Replace all "ß" with "ﷺ" in the D2-SIRAH classical layer files.

---

## CHECK 9 — NO MARKED POINT WITH STUB ARTIFACT

✅ **PASS** — All 8 domain directories (D1–D8, plus D9-ATLAS) contain their full artifact complement:

| Domain | pages_trilingual.html | education_pack.json | quran_layer | hadith_layer | classical_layer | graph_layer | gates_audit |
|--------|----------------------|--------------------|----|-----|------|-----|-----|
| D1 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| D2 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| D3 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| D4 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| D5 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| D6 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |

| D8 | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
| D9-ATLAS | atlas.json ✅ | pillar_education.json ✅ | pillar_atlas.html ✅ | — | — | — | — |

No domain is missing a required artifact file.

## REQUIRED FIXES BEFORE PILLAR-COHERENT

### FIX-1 (Blocking): Re-run D7-WORSHIP sirah_extract.json
The extraction must target passages **about the Prophet's ﷺ personal worship practices** — passages that describe him performing tahajjud, fasting, making du'a, performing qunut. The keyword-match approach must be replaced with a semantic/contextual gate: the Prophet ﷺ must be the *subject* of the action in the passage, not merely a named participant or the keyword occurring in an unrelated chain.

**Rows to replace**: at minimum rows 2, 3, 5, 7, 8, 10, 11, 13, 14, 16, 20, 21 (12 confirmed), row 15 (marginal).

### FIX-2 (Blocking): Re-run D6-LEADERSHIP sirah_extract.json
Same root cause. The extract must target passages describing Muhammad ﷺ exercising leadership — writing covenants, arbitrating disputes, consulting companions, concluding treaties. Keywords صحيفة, حكم, عهد must be verified to refer to the Prophet ﷺ, not Ibrahim ʿalayhi as-salam, Iblis, or cosmological descriptions.

**Rows to replace**: rows 1, 5, 6, 7, 15, 16 (6 confirmed).

### FIX-3 (Non-blocking): D4-FAMILY row 16 — Tabari Khadijah
Replace with a passage about Khadijah bint Khuwaylid رضي الله عنها, not Khadijah bint Sa'id ibn Sahm. Tabari does contain passages about the Prophet's ﷺ Khadijah RA elsewhere in his corpus.

### FIX-4 (Non-blocking): D2-SIRAH classical layer "ß" honorific
Replace all occurrences of "ß" with "ﷺ" in `D2-SIRAH/classical_layer_dataset.json` and `D2-SIRAH-CHRONOLOGY/classical_layer_dataset.json` authored text (not corpus verbatim quotes).
