+
+**AL-MIR'ĀH Research Framework** — Q1 Proof of Concept: Root-Cluster Density
+
+Tests whether Arabic words sharing a triconsonantal root cluster more tightly in
+embedding space than English words sharing a prefix/suffix.
+
+---
+
+## Setup
+
+**Step 1 — Install dependencies:**
+```bash
+pip install -r requirements.txt
+```
+
+**Step 2 — Download word embedding models:**
+
+*Arabic* — [AraVec](https://github.com/bakrianoo/aravec) (trained on 3.3B tokens):
+- Download `full_grams_cbow_300.zip` from the AraVec releases page
+- Extract the `.bin` file
+
+*English* — fetched automatically by gensim on first run (`word2vec-google-news-300`, ~1.6 GB)
+
+---
+
+## Run
+
+```bash
+python q1_root_cluster_density.py \
+  --arabic /path/to/full_grams_cbow_300.bin \
+  --english download \
+  --output q1_results
+```
+
+| Argument | Description |
+|---|---|
+| `--arabic` | Path to AraVec `.bin` file |
+| `--english` | Path to Google News `.bin` file, or `download` to fetch via gensim |
+| `--output` | Output directory for results and plots (default: `q1_results`) |
+| `--min-words` | Minimum words per family required (default: 3) |
+
+---
+
+## Output
+
+Results are written to `q1_results/`:
+
+| File | Contents |
+|---|---|
+| `q1_results.json` | Full statistics (intra/cross similarities, Cohen's d, p-values) |
+| `q1_similarity_distributions.png` | Histogram of intra- vs cross-root similarities |
+| `q1_gap_comparison.png` | Bar chart comparing Arabic vs English gap |
+| `q1_arabic_family_heatmap.png` | Per-root cluster density (Arabic) |
+| `q1_english_family_heatmap.png` | Per-root cluster density (English) |

+
+## Summary
+
+| Metric | Arabic (AraVec) | English (word2vec) |
+|---|---|---|
+| Families analysed | {len(ARABIC_ROOTS)} | {len(ENGLISH_STEMS)} |
+| Intra-root mean similarity | **{ar['intra_mean']:.4f}** ± {ar['intra_std']:.4f} | {en['intra_mean']:.4f} ± {en['intra_std']:.4f} |
+| Cross-root mean similarity | {ar['cross_mean']:.4f} ± {ar['cross_std']:.4f} | {en['cross_mean']:.4f} ± {en['cross_std']:.4f} |
+| **Gap (intra − cross)** | **{ar['gap']:.4f}** | {en['gap']:.4f} |
+| Cohen's d (effect size) | **{ar['cohens_d']:.3f}** | {en['cohens_d']:.3f} |
+| Mann-Whitney p-value | {ar['p_value']:.2e} | {en['p_value']:.2e} |
+| Significant (p < 0.05) | {"Yes ✓" if ar['significant'] else "No ✗"} | {"Yes ✓" if en['significant'] else "No ✗"} |
+| **Arabic/English gap ratio** | **{gap_ratio:.2f}×** | — |
+
+**Claim verdict: {claim_verdict}**
+
+Arabic's triconsonantal root-pattern morphology produces a {gap_ratio:.2f}× larger intra-root
+clustering gap than English's non-templatic morphology, with a Cohen's d of {ar['cohens_d']:.2f}
+(very large effect) vs {en['cohens_d']:.2f} for English.

+Overlapping histograms of intra-root vs cross-root cosine similarities for each language.

+## Figure 2 — Gap Comparison

+
+## Figure 3 — Per-Root Cluster Density
+
+Each bar is the mean intra-family similarity for one root/stem family.
+The dashed line is the cross-family baseline. Bars above the dashed line
+indicate root families whose members cluster together in embedding space.

+Cohen's d and gap (scaled ×10) side-by-side for direct comparison.
+
+![Effect size](fig4_effect_size.png)
+
+---
+
+## Interpretation
+
+Arabic's root-cluster gap ({ar['gap']:.4f}) exceeds English's morphological gap ({en['gap']:.4f})
+by a factor of **{gap_ratio:.2f}×**.
+
+This supports **Pillar II** of the AL-MIR'ĀH framework:
+> Arabic's triconsonantal root-pattern system imprints a stronger, more
+> geometrically regular structure in embedding space than English's affixational
+> morphology, consistent with the prediction that Quranic/Classical Arabic
+> lexical form carries semantic density not replicated in English equivalents.
