Add Sethian Genesis (ch01 §8) + "older than the churches" antiquity (ch02)

From input/part1-sethian-genesis-research.md (compiled research).

ch01 — new §8 "The Garden Retold" (Sethian Genesis adopted as family belief):
- documented Sethian inversion (serpent = Instructor, fruit = liberation;
  Apocryphon of John / Hypostasis of the Archons / On the Origin of the World)
- belief: serpent = Sophia finishing the rescue of §4; fruit = the spark/gnosis;
  the Demiurge brands knowledge "forbidden" to guard his worship and the power
  it feeds him (ties to §6). Eden = how we first woke up, not how we fell.
- §9 (Seth): "gnosis first descended on Seth"
- §6 (Archons): Sethian texts tie the Archons to the Enoch fallen angels —
  grounds the §5 fallen-angels reading
- §11 Key Texts: add the Apocalypse of Adam
- renumbered: Garden §8, Seth §9, Salvation/steps-of-return §10, Key Texts §11;
  all cross-refs updated (ch01 footer, Part V, CLAUDE, GLOSSARY, OUTLINE)

ch02 — new section "How Old Is This, Really? — Older Than the Churches":
Sethianism/Gnosticism is pre-Christian / at least as old (Scholem; heterodox-
Jewish roots), with honest source-tension (Turner's 2nd-c. crystallization;
Irenaeus/Pseudo-Tertullian) and the late-Coptic-copies caveat. Not a daughter
of the church.

GLOSSARY: add "the serpent (of Eden)" and "the forbidden fruit / the apple."
Rename research input to the partN-topic convention.

+# Sethianism and Gnostic Texts: Synthesized Academic Overview
+
+---
+
+## 1. Historical Origins and Chronology
+
+Sethianism emerged as one of the principal currents of Gnosticism during the 2nd and 3rd centuries AD, alongside movements such as Valentinianism and Basilidianism [1]. Its exact origins remain disputed, though both sources agree on a broadly pre-Christian Judaic foundation strongly inflected by Platonic thought [1][2]. Source [2] goes further, suggesting the movement may be "probably older than the first Christian churches," a claim echoed by scholars such as Gershom Scholem, who argued that Jewish Gnosticism predates its Christian counterpart [2]. Source [1], drawing on John D. Turner, locates origins more cautiously in the 2nd century AD as a fusion of distinct Hellenistic Judaic philosophies influenced by Christianity and Middle Platonism [1]. The two sources are therefore in mild tension here: [2] implies greater antiquity, while [1] emphasizes a specifically 2nd-century crystallization.
+
+According to [1], the movement underwent **six distinct developmental phases**, beginning with two originally separate groups—the Barbeloites and the Sethites—that fused into a Christianized Sethianism by the mid-2nd century, before gradually distancing itself from Christian orthodoxy and eventually fragmenting into various sectarian groups by the 4th century. The earliest external attestation comes from **Irenaeus and Pseudo-Tertullian** in the 2nd century, where Sethians are mentioned alongside the Ophites [1].
+
+---
+
+## 2. Core Theology and Cosmology
+
+Both sources converge on the central theological architecture of Sethianism, though [2] provides more granular mythological detail.
+
+### 2.1 The Transcendent God and Emanations
+Sethian theology posits a **transcendent, hidden, unknowable God** entirely beyond ordinary description [1][2]. From this ultimate divinity emanate paired male and female divine beings called **aeons**, which together with the hidden God constitute the **Pleroma**—the fullness of the spiritual universe [2]. A notable figure within this emanatory structure is the **Barbelo**, described as a co-actor in the emanations and common throughout Sethianism [2].
+
+### 2.2 The Demiurge and the Material World
+A critical rupture in the emanatory order occurs when **Sophia** produces an unauthorized emanation, resulting in the appearance of **Yaldabaoth**, a false god or demiurge who steals divine power and proceeds to create the material world [2]. Yaldabaoth in turn generates **archons**—petty rulers who help craft the physical world—and some Sethian texts identify these archons with the fallen angels of the Enoch tradition [2]. This cosmological framework is fundamentally **dualistic**, opposing a transcendent spiritual reality against a corrupt material creation [1][2].
+
+### 2.3 Adam, Eve, and the Reinterpretation of Genesis
+Sethian theology involves a radical reinterpretation of Genesis [1]. The demiurge creates Adam and Eve, but the divine power stolen from Sophia is secretly transferred into Adam and later accessed through the eating of the forbidden fruit [2]. Crucially, the **serpent in Eden is cast as heroic and salvific** rather than adversarial; eating the fruit represents humanity's first act of liberation from the oppressive archonic powers [2]. This inversion of orthodox biblical narrative is characteristic of Sethian exegesis.
+
+### 2.4 Seth and Gnosis
+Central to the movement's identity is the veneration of **Seth**, the third son of Adam and Eve, who is portrayed as a divine incarnation [2]. Sethian theology holds that **gnosis first descended upon Seth** and was transmitted through him [1]. The movement derives its name directly from this veneration [2].
+
+---
+
+## 3. Primary Texts and Their Preservation
+
+Both sources identify an overlapping, though not identical, corpus of key texts. The **Apocryphon of John** is cited by both as foundational, containing the most famous expression of the Sethian cosmogonic myth [1][2]. Source [2] additionally lists the **Apocalypse of Adam** and the **Gospel of Judas** among Sethian texts, and notes Sethianism's influence on gnostic Christian gospels more broadly.
+
+Regarding physical preservation, [1] notes that most surviving Sethian texts exist only in **Coptic translation of Greek originals**, largely recovered from the **4th-century Nag Hammadi library**. This is a significant methodological caveat for any scholarly engagement with these texts: the manuscripts are late copies, and researchers are working at a remove from the original compositions.
+
+---
+
+## 4. Influence and Legacy
+
+Source [2] traces Sethianism's broader influence across several directions. Within antiquity, Sethian ideas are said to have shaped later Gnostic systems including the **Thomasines, Basilideans, and Valentinians** [2]. In modernity, [2] notes the emergence of **neo-Sethian movements**, such as the 19th-century **Knights of Seth**, which attempted to resurrect medieval Gnostic and dualistic Christian ideas—though this claim receives no corroboration from [1] and should be treated with caution pending further specialist sources.
+
+---
+
+## 5. Gaps and Caveats
+
+- Both sources are encyclopedic overviews rather than focused scholarly analyses; deeper engagement with primary scholarship (e.g., Turner's work cited in [1], or Scholem cited in [2]) is warranted.
+- The two sources diverge modestly on the question of chronological origins, with [2] implying pre-Christian antiquity and [1] emphasizing a 2nd-century synthesis.
+- The claim about the Gospel of Judas as a Sethian text [2] is noted but not elaborated upon and would benefit from specialist verification.
+- The late date and translated nature of surviving manuscripts [1] introduces textual uncertainty that any academic treatment must acknowledge.
