## Claim Specification

| Field | Value |
|-------|-------|
| Subject | UN General Assembly Resolution 181 (November 29, 1947) |
| Compound operator | AND — both sub-claims must hold |
| SC1 property | Percentage of Mandatory Palestine territory allocated to proposed Jewish state |
| SC1 operator | >= |
| SC1 threshold | 56.0 |
| SC1 operator_note | '56 percent' interpreted as >= 56.0. Actual figure is 56.47%. FALSE only if Jewish state received < 56% of total territory. |
| SC2 property | Jewish population as percentage of total Mandatory Palestine population circa 1947 |
| SC2 operator | < |
| SC2 threshold | 33.0 |
| SC2 operator_note | 'less than 33 percent' interpreted strictly as < 33.0. CAVEAT: No 1947 British census existed; last census was 1931. Evaluated using 1946 British Mandate estimates (608,225 / 1,845,559 = 32.96%). |

## Citation Verification Details

**B1 — Encyclopaedia Britannica**
- Status: `not_found`
- Method: n/a
- Fetch mode: live
- Impact: SC1 (land allocation ≥ 56%) depends on B1. However, B2 (Wikipedia, verified) independently confirms the same 56.47% figure with both the km² value and percentage confirmed via data value verification. SC1 conclusion does not depend solely on B1. *(Impact analysis: author analysis)*

**B2 — Wikipedia: United Nations Partition Plan for Palestine (territorial allocation)**
- Status: `verified`
- Method: full_quote
- Fetch mode: live
- Data values confirmed: jewish_km2_b2 = "15,264" ✓; jewish_pct_b2 = "56.47" ✓

**B3 — Wikipedia: United Nations Partition Plan for Palestine (1946 population)**
- Status: `verified`
- Method: full_quote
- Fetch mode: live
- Data values confirmed: jewish_pop_b3 = "608,225" ✓; total_pop_b3 = "1,845,559" ✓

**B4 — Wikipedia: Demographic history of Palestine region**
- Status: `not_found`
- Method: n/a
- Fetch mode: live
- Impact: B4 is a cross-check source for the Jewish population count (608,225). The primary source B3 is verified and independently establishes SC2. SC2 conclusion does not depend solely on B4. *(Impact analysis: author analysis)*

## Computation Traces

From proof.py inline output (execution trace):

```
B1_pct: Parsed '56.47' -> 56.47
B2_pct: Parsed '56.47' -> 56.47
SC1 land percentage: B1 (Britannica) vs B2 (Wikipedia): 56.47 vs 56.47, diff=0.0, tolerance=0.01 -> AGREE
SC2 Jewish population count: B3 vs B4: 608225 vs 608225, diff=0, tolerance=0 -> AGREE

SC1 — Land allocation: jewish_pct_b1 = 56.47
  compare: 56.47 >= 56.0 = True
SC1 holds (56.47 >= 56.0): True

  jewish_pop / total_pop * 100: jewish_pop / total_pop * 100 = 608225 / 1845559 * 100 = 32.9561
  compare: 32.95613957613926 < 33.0 = True
SC2 holds (32.9561% < 33.0%): True

  compare: 2 == 2 = True
Sub-claims holding: 2/2

## Independent Source Agreement (Rule 6)

| Cross-check | Sources | Values compared | Agreement | Tolerance |
|-------------|---------|-----------------|-----------|-----------|
| SC1 land percentage: B1 vs B2 | Britannica vs Wikipedia (Partition Plan) — different organizations, different pages | 56.47 vs 56.47 | ✓ AGREE | 0.01 absolute |
| SC2 Jewish population count: B3 vs B4 | Wikipedia (Partition Plan) vs Wikipedia (Demographic History) — different Wikipedia articles, different editorial contexts | 608,225 vs 608,225 | ✓ AGREE | 0 absolute |

Note: B2 and B3 use the same Wikipedia article URL but cite different sections (territorial allocation table vs population table) and different data values. Independence for B1/B2 is strong (different organizations). For B3/B4, independence is "independently published Wikipedia articles" — same underlying Wikimedia infrastructure but different editorial contexts. The B4 quote was not verified live, but the cross-check relies on the value matching B3 (both parsed from data_values strings), which they do.

## Adversarial Checks (Rule 5)

**Check 1**: Does the 56% figure change if desert areas are excluded or alternative boundaries are used?
- Searched for: Alternative territorial allocation figures for Resolution 181 using different boundary definitions or excluding the Negev.
- Finding: All authoritative sources cite 56.47% as total territorial allocation including the Negev. Jewish-owned land (~7%) is a distinct figure from territorial allocation.
- Breaks proof: No

**Check 2**: Was Jewish population share at or above 33% by November 1947 due to post-WWII immigration?
- Searched for: Jewish population figures specifically for late 1947. Found UNSCOP used 1946 estimates (32.96%). Some 1947-specific estimates suggest ~630,000 Jews; using 630,000 / 1,900,000 ≈ 33.2%.
- Finding: SC2 is borderline. The official figures used by UNSCOP and encyclopedias (32.96%) support the claim. Some 1947-specific estimates could push slightly above 33%. Most scholarly sources cite "approximately 31-33%."
- Breaks proof: No

**Check 3**: Is there any authoritative source placing Jewish population at 33% or above?
- Searched: Academic and encyclopedia sources. Multiple sources (Britannica, UNSCOP, Wikipedia) cite ~32-33%. Rounding of 32.96% to "33%" in popular summaries does not imply ≥ 33%.
- Finding: No credible source places Jews at significantly above 33% before November 1947.
- Breaks proof: No

**Check 4**: Was there actually a "1947 British census" as stated in the claim?
- Searched: "1947 Palestine census British Mandate." Last formal census was 1931. CJPME Factsheet 007 states "all figures following 1931 are estimates."
- Finding: No 1947 British census existed. The claim contains a factual inaccuracy in attribution. The underlying population percentage (32.96% < 33%) is correct on British Mandate estimates. Inaccuracy noted but does not invalidate SC2 numerically.
- Breaks proof: No

## Extraction Records

| Fact ID | Extracted Value | Found in Quote | Quote Snippet | Extraction Method |
|---------|----------------|----------------|---------------|------------------|
| B1_pct | 56.47 | Yes | "56.47" (data_values string) | parse_number_from_quote with r"([\d.]+)" |
| B2_pct | 56.47 | Yes | "56.47" (data_values string) | parse_number_from_quote with r"([\d.]+)" |
| B3_pop_jewish | 608,225 | Yes | "608,225" (data_values string) | str.replace(",","") then int() |
| B3_pop_total | 1,845,559 | Yes | "1,845,559" (data_values string) | str.replace(",","") then int() |
| B4_pop_jewish | 608,225 | Yes | "608,225" (data_values string) | str.replace(",","") then int() |

All values are programmatically derived from empirical_facts data_values strings — no hand-typed numeric values. Comma-stripped extraction (`str.replace(",", "")`) is used for integer population counts; `parse_number_from_quote` is used for decimal percentages.
