feat(lenses): Exodus 21-30 lens content, batch 3 of Exodus pilot (#820, #1781)

[CraigBuckmaster]

Summary

Batch 3 of the Exodus pilot. Book of the Covenant (ex21–23) + covenant ratification (ex24) + tabernacle instructions (ex25–30). 35 entries across 10 chapters, all 100/100 on lens_quality_scorer after one small fix pass.

The lowest per-chapter density of any batch in the pilot — average 3.5 lenses/chapter — and that's correct. Legal codes and architectural specifications don't need six lenses each; forcing them would dilute. ex24 is the only peak (5 lenses) because covenant ratification is the chapter where law-and-construction become liturgy.

Per-chapter lens distribution

Chapter	Lenses	Notes
ex21 — Servants; injury laws	3	literary, redemptive, canonical
ex22 — Property + vulnerable protection	3	literary, redemptive, canonical
ex23 — Justice + festivals + angel	4	literary, redemptive, typological, canonical
ex24 — Covenant ratification	5	literary, typological, christocentric, redemptive, canonical
ex25 — Ark; mercy seat; lampstand	4	grammatical, typological, christocentric, canonical
ex26 — Coverings; veils	3	literary, typological, christocentric
ex27 — Bronze altar; courtyard	3	literary, typological, redemptive
ex28 — Priestly garments	3	grammatical, typological, christocentric
ex29 — Priestly consecration	4	literary, typological, christocentric, devotional
ex30 — Incense; basin; oil	3	literary, typological, canonical

Total 35 entries, average 3.5 lenses/chapter.

Theological highlights

• ex24 christocentric: v 8's "blood of the covenant" is the formula Christ redeploys verbatim at Mt 26:28 ("this is my blood of the covenant"). The Last Supper deliberately rewrites Sinai into the upper room — same blood-grammar, new mediator.
• ex25 grammatical: kapporet (mercy seat) from root kafar ("to cover, atone") — not throne-cushion but atonement-cover. Cherubim guarding the mercy seat (v 18) recall Gen 3:24's cherubim guarding Eden; Christ as both throne and atonement reopens what Eden's cherubim closed.
• ex25 canonical: v 40's "according to the pattern shown to you on the mountain" → Heb 8:5 ("a copy and shadow of the heavenly things") → Heb 9:24 (Christ entering the heavenly archetype). The tabernacle is reverse-engineered from heaven.
• ex26 typological: the inner veil (vv 31–33) is built to be torn — Mark 15:38 tears it from top to bottom; Heb 10:19–20 names Christ's flesh the new way through. Cherubim woven into the veil match the ark's cherubim — guards on both sides of the boundary.
• ex28 typological: Aaron carries the twelve tribes' names on his shoulders and over his heart (vv 9–12, 29) — high priest physically bears Israel into God's presence. Heb 4:14: Christ as great high priest carries his people the same way.
• ex29 christocentric: blood on ear/thumb/toe (v 20) consecrates hearing, doing, walking — whole-life purification. Heb 7:27: Christ's once-for-all sacrifice abolishes the cycle while fulfilling its meaning.
• ex30 typological: the half-shekel atonement-money is "the same for rich and poor" (v 15) — covenant atonement levels the human field. The pattern points to one ransom, every soul, no scaling.
• ex23 typological: "my angel will go before you" with "my name in him" (vv 20–21) — patristic readers saw the angel of Yahweh as pre-incarnate appearance. Defensible across multiple traditions.

Drafting note — token-swap fixes (lesson surfaced)

Three entries needed a single fix iteration. The pattern:

Entry	Issue
ex25 typological	used "thread" (a canonical token) without a typological token
ex25 canonical	used "pattern" (a typological token) without a canonical token
ex28 typological	lacked any of: type/foreshadow/anticipates/echoes/prefigures

Same root cause as the gen42/43 structural/narrator fix in batch 4 of the Genesis pilot: the rubric must_have_one_of lists are strict substring matches, and the typological/canonical token sets overlap conceptually but are scored disjointly. Drafting under the assumption that "this is clearly a typological entry" doesn't help if the entry uses canonical tokens — the scorer doesn't read the lens label, only the substrings.

Suggested rubric improvement (would be ~5 min): the rubric file already separates these lists; consider adding a small overlap allowance (e.g., "thread" → counts for both) or making each lens's must_have_one_of more distinct. Alternatively, add this to the drafting checklist: "verify each lens entry contains a token from that lens's specific list, not the conceptual neighbour".

Three quick str_replace swaps fixed all three. No content rewrite.

Branch / merge notes

• Branched off master at 70d3f30 (pre-feat(lenses): Exodus 11-20 lens content, batch 2 of Exodus pilot (#820, #1781) #1798).
• Non-overlapping with feat(lenses): Exodus 11-20 lens content, batch 2 of Exodus pilot (#820, #1781) #1798 (different chapter files); merge order flexible.
• Post-merge total: 303 + 35 = 338 lens contents (Genesis 214 + Exodus 124).

Watch list for tier-2 audit

Five entries flagged for editor review:

1. ex23 typological — "patristic readers saw the angel of Yahweh as pre-incarnate appearance" — defensible across Justin/Irenaeus/Calvin but is a classical Reformed reading; some Eastern traditions are more hesitant.
2. ex24 christocentric — Mt 26:28 cited verbatim of v 8 ("blood of the covenant"); the connection is direct lexical citation but reads tightly compressed.
3. ex25 christocentric — Gen 3:24 cherubim → ex 25:18 cherubim → Christ reopens Eden is a defensible patristic-Reformed move but covers a lot of ground in three lines.
4. ex26 typological — "the chapter's veil is built to be torn" is rhetorically strong; sound but interpretive.
5. ex28 christocentric — gold-plate "holy to the LORD" → Christ "bears not flawed worship but the worshippers themselves" is a creative theological move; defensible but worth tier-2 calibration.

Rollback plan

Revert the merge commit. The 10 new chapter files are additive and isolated under content/hermeneutic_lenses/chapters/; no existing content, schema, or app code is touched.

Roadmap

After this lands, batch 4 (ex31–ex40) closes the Exodus pilot. Golden calf, glory, covenant renewal, tabernacle construction. Expected high density on ex32 (calf), ex33 (glory), ex34 (renewal); construction chapters (ex36–39) will be sparse like this batch.

Refs #820. Closes part of #1781.
