## Claim Specification

*Source: proof.py JSON summary*

| Field | Value |
|-------|-------|
| Subject | 2005 Israeli disengagement from Gaza and its aftermath |
| Sub-claim SC1 | All Israeli civilian settlements in Gaza removed in 2005 |
| SC1 operator | ≥ 2 confirming sources |
| SC1 operator_note | A single remaining settlement would disprove this sub-claim |
| Sub-claim SC2 | All Israeli military outposts/installations in Gaza removed in 2005 |
| SC2 operator | ≥ 1 confirming source |
| SC2 operator_note | Airspace/naval control retention noted but does not contradict ground outpost removal |
| Sub-claim SC3 | Hamas won the January 2006 Palestinian parliamentary elections |
| SC3 operator | ≥ 2 confirming sources |
| SC3 operator_note | "Winning" = parliamentary majority (≥67 of 132 seats) |
| Sub-claim SC4 | Hamas achieved complete takeover of Gaza territory in 2007 |
| SC4 operator | ≥ 2 confirming sources |
| SC4 operator_note | All PA institutions in Gaza seized; West Bank rival PA does not negate Gaza control |

## Independent Source Agreement (Rule 6)

*Source: proof.py JSON summary*

| Sub-claim | Sources Checked | Confirming | Agreement |
|-----------|----------------|------------|-----------|
| SC1 (settlements removed) | 2 (B1 Wikipedia, B2 Britannica) | 2/2 | Yes |
| SC3 (Hamas Jan 2006 win) | 2 (B4 Wikipedia, B5 GlobalSecurity) | 2/2 | Yes |
| SC4 (Hamas 2007 takeover) | 2 (B6 Wikipedia, B7 ECF) | 2/2 | Yes |

SC2 uses a single source (B3, ADL). Independence for SC2 is limited; however, B1 (Wikipedia) additionally describes the IDF withdrawal of forces on September 12, 2005, providing corroborating context. *Source: author analysis*

---

## Adversarial Checks (Rule 5)

*Source: proof.py JSON summary*

**Check 1: Did any settlement or installation remain after the 2005 disengagement?**
- Search: "Israeli settlement remained Gaza after disengagement 2005" and "Gaza military base retained Israel 2005 exception"
- Finding: No civilian settlement or ground military installation remained. All 21 settlements were dismantled; IDF ground forces withdrew fully by September 12, 2005. Israel retained aerial and naval control (airspace, coastline), which the UN and human rights bodies argue constitutes continued occupation, but no ground outposts remained on Gaza soil.
- Breaks proof: No

**Check 2: Did Hamas win a parliamentary majority, or only a plurality?**
- Search: Verified seat count: 74 of 132 seats; majority threshold = 67 seats. 74 > 67, confirmed by Wikipedia and GlobalSecurity.
- Finding: Hamas won 74 of 132 seats (56.1%), a clear majority enabling government formation without coalition partners.
- Breaks proof: No

**Check 3: Was the Hamas 2007 Gaza takeover truly "complete"?**
- Search: "Hamas 2007 Gaza takeover incomplete Fatah retained area" and Battle of Gaza (2007) article.
- Finding: Hamas seized all PA government institutions in Gaza by June 15, 2007. Abbas established a rival West Bank government, but no part of Gaza territory remained under PA/Fatah control. ECF: "complete victory"; Wikipedia: "completed taking control."
- Breaks proof: No

**Check 4: Does "resulted in" require strict causal proof?**
- Search: "Hamas 2006 election win causes disengagement Fatah corruption" — reviewed policy and academic sources.
- Finding: Causation is debated (co-causes include Fatah corruption, Hamas's social network). The temporal sequence is uncontested. The proof interprets "resulted in" as verified sequence with widely recognized causal context; strict causal proof is noted as beyond scope.
- Breaks proof: No

|---------|--------|------|------|------|
| B1 | wikipedia.org | reference | 3 | Established reference source |
| B2 | britannica.com | reference | 3 | Established reference source |
| B3 | adl.org | unknown | 2 | Unclassified domain — verify source authority manually. ADL is an established civil rights organization; its factual backgrounders on the Israeli-Palestinian conflict are widely cited. |
| B4 | wikipedia.org | reference | 3 | Established reference source |
| B5 | globalsecurity.org | unknown | 2 | Unclassified domain — verify source authority manually. GlobalSecurity.org is a widely used defense/security reference database. |

| B7 | org.il | unknown | 2 | Unclassified domain — verify source authority manually. ECF (Economic Cooperation Foundation) is an Israeli policy research body; its event summaries are factual references. |

Note: 3 citations (B3, B5, B7) are from tier-2 sources. The core factual claims from each are corroborated by tier-3 reference sources: SC2 is corroborated by the general Wikipedia disengagement article; SC3's Hamas win is corroborated by Wikipedia (B4); SC4's Hamas takeover is corroborated by Wikipedia (B6). *Source: author analysis*

All 7 keywords were found in their respective quotes. Normalization note: B4's citation required aggressive normalization at the URL-fetch level (fragment match), but the keyword "25 January 2006" was found directly in the stored quote string without normalization.
