Task #13C — WS1/WS6 ancient-arc content build (Ch 2-38) — chunk plan + status

The last piece of Task #13 (whole-arc enrichment). The modern arc (Ch 39-65) got its WS3/WS4 content re-flesh in Task #48; the endgame (66-77) is done; this fills the ancient arc (Ch 2-38) with the WS1 opportunity-hook + WS6 situation content layer. Driver: docs/proposals/aaa_ws1_opportunity_matrix.md (per-chapter inventory) + docs/proposals/AAA_REARCHITECTURE_PROPOSAL.md (WS1/WS6 synthesis).

Discipline (every chunk)

• WEAVE a beat INSIDE the existing node (node count LOCKED, 79); do not add ## sections or rewrite chapters.
• Reveal: all Ch 2-38 are PRE-Ch-38 reveal ceiling — no House/pattern/thesis/Grand-Sage; family at most unnamed unease; no negated who-frame.
• Care (§17.1): each living tradition honored with weight; the high-care nodes (Ch 29 Sámi, Ch 28 slavery/HL_0003, and any sacred content) get the strictest handling.
• §17.14 format; pronoun register per chapter (Ch 2-11 "the child/they", Ch 12+ "she/her"); companion = the healer's child (Ntala).
• Author -> fresh-context adversarial 3-lens re-verify (reveal/care/coherence) -> fix-forward -> gates 10/10 -> commit + tag.

THE WS7 REGISTRY BLOCK (important)

Much of the WS1 inventory routes to two NEW registries that need Josh's WS7 system sign-off: MG_ (Minigame/Contest) and VH_ (Vehicle/Mount). These are NOT yet created (per the standing handoff). So this build authors the spine BEATS (the playable contests, the ownable-vessel debuts, the minigame moments) and NOTES the registry hand-off — it does NOT create MG_/VH_. Registries that EXIST and CAN take rows now: Boss_Encounter (the dragon lineage + bestiary bosses), Cross_Cultural_Link_Graph (door-seeds + L3 lattices), School_Registry (Kalaripayattu, Eleusis, the Mithraic ladder). Any registry edit refreshes docs/fidelity_baseline.json via registry_fidelity.py --emit-baseline in the same commit.

Chunks (ranked by value)

1. 13C-1 — Games & Contests spine (Josh's flagship; the single most-neglected category, NO debut in Ch 2-38). Ch 3 caci (arc's first playable contest), Ch 7 Kalaripayattu (martial school), Ch 22 Naadam (tournament), Ch 23 Olympia+pankration (Olympic origin), Ch 28 the CAPTURE flagship (captured->ludus->fight-out->uprising, HL_0003 high-care). STATUS: DONE (spine/13c-games). All 5 authored + adversarially verified (CH_07/22/23 GO; CH_03/28 GO_WITH_FIXES applied). The playable-contest pillar now DEBUTS: caci is the arc's first fought/scored contest; Kalari a graded martial school; Naadam a tournament; Olympia the pankration + the gladiator->Olympics origin-anchor; Ch 28 the capture->ludus->uprising vulnerability flagship (the enslaved are the allies freed, HL_0003 intact). The MG_/School registry rows are HELD for the WS7 sign-off.

2. 13C-2 — the Thread-2 dragon/serpent bestiary lineage. Ch 15 Apophis, 17 Tiamat + Humbaba, 18 Lotan/Leviathan, 19 Azhi Dahaka (Damavand), 21 longwang (dragon-king), 24 Jormungandr, 25 Illuyanka — staged as real Boss_Encounter rows + spine beats with a shared seven-head/serpent archetype and explicit L3 cross-links (self-assembling "similar-monsters" payoff + pre-populates the Realm-Road dragon lineage). Highest-leverage, lowest-cost span fix. STATUS: DONE (spine/13c-dragons, the Ch 18/19/21/24/25 span — each staged as a real fought/contended encounter; CH_18 Litan kept mimic-only per its §17.1 elevated-care design + flagged D-DRAGON-18). FOLLOW-ON: the Boss_Encounter dragon rows + seven-head-archetype link rows (held with WS7). Ch 15 Apophis + Ch 17 Tiamat/Humbaba deferred (denser/sensitive nodes → fold into 13C-3 or a follow-on).

3. 13C-3 — Realm-Road otherworld door-seeds. Ch 5 Borobudur->Naraka/Meru, 9 Lalibela (descent), 15 Duat (exists), 17 Inanna's seven gates->Kur, 23 Eleusis->Hades, 24 Yggdrasil/Annwn, 26 Nav, 30 Annwn, 33/37 immram (Brendan), 38 Atlantis-Ridge. Pillar-5 Cross_Cultural_Link_Graph rows naming their WS2 slot + a threshold-taste beat (a door SEEN/tasted, not crossed). Near-zero node cost; makes the endgame realms pay off earlier. STATUS: PENDING.

4. 13C-4 — folk-monster / non-dragon bestiary bosses. Ch 2 Ebu Gogo (+ Ch 6 nittaewo era-rhyme), Ch 6 the eighteen Sanni disease-demon gauntlet, Ch 26 Koschei nested-vulnerability boss (+ Baba Yaga), Ch 29 Stallu (the ONE care-clean way to give protected Sapmi real L1 action, folktale-being), Ch 31 Herensuge/Mari/Basajaun, Ch 34 Guayota (sealed fire-demon). Boss_Encounter/folklore rows + beats. STATUS: PENDING.

5. 13C-5 — WS6 era-rhyme situation beats + the vulnerability spine. The 8 ancient->modern pairs (arena->stadium Ch 28<->61 [seeded in 13C-1], piracy Ch 8<->39, caravan Ch 20<->40, Naadam Ch 22<->60, siege Ch 25<->65, trial Ch 23<->49, treasure-race Ch 27<->50, voyage Ch 36<->55) + the capture/vulnerability placements (Ch 33 near-capture SEED, Ch 36 nature's-indifference). Situation beats inside existing nodes. STATUS: PENDING (Ch 28 capture done in 13C-1).

6. 13C-6 — L1.5 daily-life / festival immersion + culture minigames (the "fun is allowed" tone). The felt daily-life layer per chapter (Ch 3 buffalo-feast, Ch 9 buna coffee, Ch 27 feast, Ch 35 batuku/morna+cachupa, Ch 38 Espirito Santo) + the culture minigame moments (Senet Ch 15, Ifa/mancala Ch 12, Go/feng-shui/I-Ching Ch 21, dice Ch 16, fidchell Ch 30, pelota Ch 31). Most route to the WS7 MG_ registry (HELD) — author the felt beats, note the registry. STATUS: PENDING.

After 13C

Task #15 — final whole-arc verification (+ the deferred P8 items: they->she marker, "for the first time" rationing, arrival-sentence variety, Ch 36-37 merge) -> Fable-5 handoff. Plus the WS7 decision batch for Josh (MG_/VH_ registries + the systems).
