Theological highlights

• ex32 substitutionary mediation — Moses's "blot me out" (v 32) drafted as the typological/christocentric anchor, with the canonical entry tracing the calf episode's later-canonical echoes (Deut 9, Neh 9, Ps 106, Acts 7, 1 Cor 10) rather than restating the themes panel.
• ex33 panim chain — grammatical lens anchored on the Hebrew (panim, panai, achor); typological angle uses John 1:18's "no one has seen God except the Son" to read Moses's partial sight as Sinai-shadow → Bethlehem-disclosure.
• ex34 vv 6-7 formula — themes already cites Ps 86, Jonah 4, Joel 2; the canonical entry deliberately uses the unmentioned echoes (Num 14:18, Neh 9:17, Pss 103:8 / 145:8) to avoid restatement. The typological entry works the veil-on/veil-off pattern (vv 33-35 → 2 Cor 3) on a different lexical handle from the themes' "shining face" framing.
• ex37 kapporet → hilasterion → Christ — anchors the Hebrew/LXX/Pauline chain through Rom 3:25.
• ex40 capstone redemptive arc — Eden-cast-out inverted into Yahweh-moves-into-camp; christocentric lens uses John 1:14's eskenosen root to land the tabernacle imagery in incarnation.

Plagiarism guards applied

• ex32: themes lists "blot me out" — typological entry uses the phrase but reframes around "substitutionary pattern" / "greater Mediator" / "cut off for the people he loves"; christocentric entry pivots to "names blotted from one book are written in the Lamb's", which themes does not touch.
• ex33: themes lists v 11's "face to face" and v 18's "show me your glory" — grammatical entry shifts to the Hebrew lexical chain (panim / panai / achor), and the christocentric entry anchors v 14's "my Presence will go with you" as the Immanuel seed rather than restating the glory-request narrative.
• ex34: themes already lists the cross-canonical echoes (Ps 86:15, Jonah 4:2, Joel 2:13) — canonical entry uses Num 14:18 / Neh 9:17 / Pss 103:8 / 145:8 instead. Themes mentions 2 Cor 3 with the shining face — typological entry pivots to the veil-on/veil-off pattern of vv 33-35 instead.
• ex40: themes calls out "tabernacle erected" / "glory cloud fills" — christocentric entry brings the Greek eskenosen root from John 1:14 into focus, redemptive entry frames the Eden-inversion arc, neither of which themes covers.

Lens-token discipline

Every entry verified against the lens-specific must_have_one_of list in _tools/lens_rubrics.json:

• typological entries use type / pattern / prefigures / anticipates / shadow (never "thread")
• canonical entries use echoes / throughout Scripture / thread / canon (never "pattern")
• christocentric entries name Christ / Jesus explicitly (no oblique "the Messiah" without follow-up)
• grammatical entries cite the Hebrew lexeme (elohim, chesed v'emet, panim, kapporet)

Tier-2 audit watch list

These entries make explicit cross-canonical or LXX claims that a tier-2 audit may want to spot-check:

• ex32 / canonical — five-canon citation chain (Deut 9:8-21, Neh 9:18, Ps 106:19-23, Acts 7:39-43, 1 Cor 10:7)
• ex33 / canonical — Pss 27:8 / 42:2 / 63:2 → Mt 5:8 → 1 Jn 3:2 face-of-God thread
• ex34 / canonical — Num 14:18, Neh 9:17, Pss 103:8 / 145:8 attribute-formula echoes
• ex34 / christocentric — chesed v'emet → John 1:14 "grace and truth" Hebrew-pair claim
• ex37 / christocentric — kapporet → LXX hilasterion → Rom 3:25 chain
• ex40 / christocentric — John 1:14 eskenosen lexical claim
• ex40 / canonical — Num 9:15-23 / 1 Kgs 8:10-11 / Ezek 10 + 43 / John 1:14 / Rev 21:3 cloud-fire thread

Pilot summary (after merge)

• Genesis pilot: 50 chapters, 214 entries (per Epic Epic: Hermeneutic Lenses Content #820 history)
• Exodus pilot: 40 chapters, 124 entries (90 from prior batches + 39 from this PR — total in DB after merge: 377 with both pilots combined)

After this merges, the Exodus pilot is complete. Issue #1781 can be closed.

Out of scope

• No content/exodus/* changes
• No app code changes
• No db-manifest.json / explore-images.json drift (reverted)
• No new scholar entries (ex34 / ex40 typological work uses existing Calvin / MacArthur scholars on Exodus)
