feat(lenses): Joshua 1-24 lens content, batch 1 of Historical Books (#820, #1783)

[CraigBuckmaster]

Summary

First batch of #1783 (Historical Books). Sets the template for narrative-conquest genre. Joshua 1-24 — 73 lens entries across all 24 chapter files.

This is the I-do tier per the hybrid plan: Joshua sets the reference implementation, then Claude Code drafts Judges through Nehemiah against this pattern with PR-time review.

Per-chapter distribution (73 total)

Density	Chapters	Notes
5 lenses	jos2, jos6, jos24	Rahab / Jericho / Shechem covenant renewal — the three theology peaks
4 lenses	jos1, jos3, jos5, jos7	Commission / Jordan crossing / Commander / Achan
3 lenses	jos4, jos8, jos9, jos10, jos14, jos20, jos22, jos23	Memorials, Ai, Gibeonites, sun-stops, Caleb, refuge cities, altar-of-witness, farewell
2 lenses	jos11, jos12, jos13, jos15, jos16, jos17, jos18, jos19, jos21	Allotment / boundary-list chapters (sparse by design)

Average guidance length: 226 chars (target 250, hard ceiling 280).

Christocentric / typological anchors

• jos2.christo — Rahab anchored on Mt 1:5 (Christ's genealogy) + Heb 11:31
• jos2.typological — scarlet cord prefigures Passover-blood pattern, points to the cross
• jos5.typological — Commander of the LORD's army anchored on Rev 19:11-16 (divine-warrior Christ)
• jos6.christocentric — Jericho walls anchored on Heb 11:30 (faith-action)
• jos7.canonical — Achan pattern anchored on Acts 5:1-11 (Ananias and Sapphira)
• jos11.redemptive — 'the land had rest' anchored on Heb 4:8-9 (greater Joshua brings greater rest)
• jos20.typological — six cities of refuge anchored on Heb 6:18 (Christ as refuge)
• jos21.canonical — 'not one of all the LORD's good promises failed' (v 45) anchored on 2 Cor 1:20 (all promises Yes in Christ)
• jos24.christocentric — 'choose this day' anchored on Mt 6:24 (no one can serve two masters)
• jos24.canonical — two-ways summons threads from Deut 30:19 to 1 Kgs 18:21 to Mt 7:13-14

Plagiarism guards applied

• jos2 Rahab — five lenses each anchor at a distinct point: literary on the three-part confession (vv 9-11); christocentric on the scarlet cord (vv 12-21) → Mt 1:5 / Heb 11:31; typological on the same pledge but reading the Passover-pattern; canonical on the wider NT echo network; mission on vv 8-13's outsider-as-first-convert
• jos6 Jericho — five lenses on different scenes: literary on the seven-day march structure; christocentric on v 20 (Heb 11:30); redemptive on vv 22-25 (Rahab-rescue intact mid-judgment); devotional on vv 1-5's strange instructions; mission on vv 23-25 (Rahab's family woven into Israel)
• jos24 Shechem — five lenses with separate verse anchors: literary on vv 1-13's twentyfold-I divine recital; redemptive on the Abraham-to-conquest arc compressed; christocentric on vv 14-15 → Mt 6:24; canonical on vv 14-15's two-ways thread; devotional on the leader's confession 'as for me and my household'

Joshua-specific structural notes (for downstream batches)

Two findings from the scout that affect Claude Code briefing:

• chapter_id format is josh{N}, not jos{N} — caught at scout time, no failed builds.
• Joshua uses Howard (NAC) + Hess (TOTC) as primary scholar set — NOT Craigie/Tigay (those are Deuteronomy specialists, no panels for them in Joshua chapters). Verified by inventorying section-panel keys across all 24 source chapters before authoring. This swap is reflected in the panel-mix templates.

Tier-2 audit watch list

NT-citation entries warranting review:

• jos1.canonical — Heb 13:5-6 (the headline 'never leave you nor forsake you' citation)
• jos2.christocentric, jos2.canonical — Mt 1:5 / Heb 11:31 / Jas 2:25 Rahab thread
• jos3.typological — baptism-typology (covenant-Reformed reading; flag for tradition-specificity)
• jos5.typological — Rev 19:11-16 divine-warrior reading
• jos6.christocentric — Heb 11:30 (the headline Jericho-faith citation)
• jos7.canonical — Acts 5:1-11 corporate-consequence pattern
• jos11.redemptive — Heb 4:8-9 (the headline 'greater Joshua brings greater rest' citation)
• jos15.canonical — Othniel → Judg 3:9-11 thread
• jos18.canonical — Shiloh → 1 Sam 1-4 → Jer 7:12-14 thread
• jos20.typological — Heb 6:18 refuge-as-Christ reading
• jos21.canonical — 2 Cor 1:20 (the headline promise-keeping citation)
• jos22.canonical — Phinehas continuity Num 25 → Josh 22
• jos24.christocentric — Mt 6:24 two-masters reading
• jos24.canonical — Deut 30:19 → 1 Kgs 18:21 → Mt 7:13-14 two-ways thread

All NT anchors are positions scholars genuinely hold; no fabricated attributions.

Conventions followed

• Scholar set verified by source-chapter inventory: Howard (NAC) + Hess (TOTC) + MacArthur + Calvin + NET
• Panel-mix templates: identical shape to Pentateuch, with craigie/tigay swapped for howard/hess
• Rubric-token discipline maintained — caught one 'structural' (no structure substring) miss at draft-time, fixed before write
• All in-chapter verse refs use explicit v N / vv N-M form within each chapter's max_v
• Banned filler patterns absent
• Drift on app/assets/db-manifest.json and app/assets/explore-images.json dropped before staging

Rollback plan

Adds 24 new files only, modifies no existing content. git revert <merge-commit> returns chapter_lens_content to 661 rows after next DB rebuild.

Hybrid plan handoff

Once this merges, the next steps for #1783:

1. Ruth + Esther (small, theology-dense): I do these
2. Judges through Nehemiah: Claude Code drafts against the pattern set here, I review at PR time

A Claude Code briefing document with precise prompts for each book is being prepared in parallel and will be posted on #1783 shortly.
