Trade Presence Briefs — Slice Half CH_08 to CH_13 (Swahili Coast → South Africa)

CANON SUBORDINATION — this document is PROPOSAL-TIER: it serves canon and never outranks it.
The canon: the CVD · the T1 foundation docs · the T0 registries (registries/) · the spine
(docs/spine/CH_*.md) · the region pages (_source/02_Tier_2_Region_Pages/). Authority order:
docs/DOC_MAP.md § 0.
Canon served: T1_Trades_Master [ACTIVE v1.0] · T0_Trade_Registry · T0_Trade_Good ·
T0_Gather_Node_Registry · T0_Recipe · T0_Quest_Seed_Registry · T0_Flora_Registry ·

(swahili_coast, ethiopia, rift_valley, central_africa_congo, west_africa, south_africa).
READ THAT CANON FIRST. If this document disagrees with canon, CANON WINS and this document is
the defect. Nothing here is applied until it is ratified into canon.

Status: PROPOSAL-TIER. Slice trade-presence lane (ledger pipeline B3-adjacent), covering CH_08

through CH_13. **Scope boundary, binding and self-imposed: these are TRADE PRESENCE BRIEFS, not gate

quests.** No quest id is minted, no registry row is written, no gate content is authored. The 120

mastery quest gates (Q_TR1_NEO … Q_TR10_MGS, T1_Trades_Master §5 L156-194) are a banned surface

for this lane; the 119 unauthored gates stay banned behind the B3 exemplar's Josh grade and

docs/proposals/TRADE_GATE_EXEMPLAR_Q_TR6_NEO.md is read-only register reference here.

Router note, per SUBAGENT_CONTRACT clause 2: harness/route.py carries **no work-kind entry for

trade-presence authoring**. The nearest entry, registry, was run

(python harness/route.py registry --chapter CH_08 --region swahili_coast) and its read-order

discipline was followed — the owning T1 doc before any structured claim, then the chapter's own spine

node, then the registries. The canon nodes actually read in full are named in the DERIVATION block.

No gate content is imported and no gate is authored.

NOT DERIVED (authored judgment, and why it had no canon home):

SUBSTRATE (T1_Trades_Master §3.11, and every page's own S14 wording), but has no term for "a craft

the chapter stages in the world without any trade routing it." Four surfaces in this slice half are

in exactly that condition and would otherwise be misfiled either as invented presence or as a false

absence. The class is a reading aid in this document only; it mints nothing.

selection of which cited material becomes a gather node is design judgment with no canon home,

because T0_Gather_Node_Registry has zero rows for these regions and no spine [POPULATE→] line

names it for them. They are firewalled as PROPOSED, carry no ids, and are not applied.

grain: "TRADE_10 Fishing and Navigation roots its ANCIENT home base here… the protagonist's first

returnable coastal rootedness and the first bench that is theirs to come back to." This is the whole

ladder's home base — every later Trade-10 rung hangs off what this coast teaches.

(a) Ambient craft presence, anchored to zones and beats canon already stages

protagonist on the mtepe learning "the plank-stitching and the rigging traverse." The page's

attestation is Ibn Jubayr on vessels at Aydhab, "carvel-built with planks stitched with coconut

fibre through holes bored at intervals near the edges of adjacent planks" (swahili_coast L1180-1182

[SRC_00198, p. 2]). The material chain is complete and gatherable: "palm to fibre to cord to hull —

and the cord is a gatherable, workable, spendable thing" (L207-208).

that gives is a boat that survives ground a rigid one would not… the single best worldview lesson

in the region's trade, and it is literally true." This is T1_Trades_Master §10.5 L307 satisfied

without a monologue — the lesson is in the hull.

Indo-Arabian and two composite, plus a 1.2 m Indo-Arabian shank at Kilwa (L1195-1198); one day's

sailing at roughly 80-100 km with the record's own error terms — wind, current, night sailing,

wreck avoidance, trading time (L1199-1202). The page's design line is the correct trade-mastery

shape: "the reward for mastery is a smaller error bar rather than a bigger number."

usable only at high tide, shallow creeks for small narrow craft, under the record's own port

trade's map legend and is already canon.

hazard zones" (CH_08 L124-126). The Trade-10 curriculum and the chapter's puzzle surface are the

same system.

revetment are the Trade-8 Engineering substrate seeds for this region (echo-seeds; the Trade-8 home

roots elsewhere in the arc)" (swahili_coast L695-697). The chain is walkable end to end: "quarry the

reef, burn the kiln, hammer the kokoto, lay the course, plaster the floor" (L647-648), with four

superimposed lime-kiln phases calibrated 1022-1329 (L644-646 [SRC_00166, p. 13]).

Section 9 as substrate without a home base" (L1228). The cloth economy is unusually loaded here:

silk and cotton cloths and turbans, lengths of cloth as the price of an island, and cloth as an

offering to the spirits of a place (L801-804) — "this region's most socially loaded good and the

market should price it that way."

(b) Teacher and mentor figures canon already names

"the dhow captain who teaches the Trade-10 navigation craft and never asks about the cloth wound

over the ears." Register per T1_Trades_Master §8.4 L256-258: this is institutional-individual —

a named master, a fixed bench, an identifiable craft lineage. Standing note carried, not resolved:

CH_08 L323 records the D-CAST ruling (Josh, 2026-07-19) that Binti Hassan is an

invested_sticky ship-keeper joining at Ch 8 and present to Ch 65, and that this spine entry still

carries the superseded recurring-NPC model in four places. **That reconciliation is the director's,

not this lane's** — but it matters to trade presence, because a trade master who becomes a

travelling companion is the only such case in the slice half, and the Trade-10 bench has to remain

returnable whether or not she is aboard.

correct for seed-tier presence and is not a gap to fill.

(c) Material and gather surfaces — and the honest gap

GAP, stated first. T0_Gather_Node_Registry carries zero rows for swahili_coast (24 rows

total, all flores_island / bali / sumatra_java / angkor_khmer). T0_Flora_Registry carries **zero

flora rows** for this region, so a flora_gather node here has no yields_ref target to resolve.

T0_Creature_Roster DOES carry 11 swahili_coast rows, so a fauna- or marine-yield node could

resolve its FK today. This is a registry-population gap, not a substrate gap: the page carries one of

the most complete gather tables in the corpus and it is simply unrowed.

What canon already attests as gatherable (cited, and the strongest gather substrate in this slice

half): four distinct shellfish grounds — "mangrove forest, intertidal sand, seagrass, and rock — four

gathering grounds, each with its own species, one of them a by-product of the lime industry"

(swahili_coast L260-263 [SRC_00196, p. 19]); fish traps "built at the landing place… a placed,

tended, returned-to structure — the shape a Trade-10 gather loop wants rather than a swing-at-a-node

loop" (L264-267); mangrove poles cut for export and coconut fibre for cord and hull stitching

(L1214-1216, L200-208); coral rag and reef limestone quarried and burnt for lime (L764-766).

Blocking condition on the flora-class rows: none of the above is a flora_gather yielding a

T0_Flora_Registry id, precisely because that registry has no swahili_coast rows. The coir line is

the one that would need a flora row minted first, and this lane does not mint it.

(d) Vendor and exchange moments, per the page's own S9

The Swahili Coast is an Indian-Ocean trade civilization and its S9 is correspondingly dense — this is

the only node in the slice half where "commerce as a practice rather than a trade" is a beat in its

own right (CH_08 L27, and CH08_B02 at L108-112, mode trade).

value legible in repair — a riveted blue-and-white plate, a re-cut stoneware bowl base (L812-815);

and a real economic gradient, since import density at inland and rural sites is "almost

insignificant beside a stonetown's" (L815-818). **The same bowl means one thing in the harbour

quarter and another an hour inland** — that is the vendor system's design premise and it is

attested, not invented.

actually cannot sail without, and it is the player's reliable early income" (L805-807).

The page repeats it as a region seed at L1150-1152: "the least glamorous and most reliable early

work on the coast, and the honest way a child earns a bench."

"ritual dues owed three times across the millet cycle and again on hunting and on net and trap

fishing, and permission to use ground obtained through the same channel" (L1232-1234 [SRC_00313,

p. 3]). The page ties the Trade-10 round to ws.community_state_per_region and

ws.identity_hiding_status through it, "with progression never touched."

TG_0025-27 as above. The elevated-care ivory row and the slave-trade substrate are the two places

where the vendor layer touches the chapter's elevated-care material; CH_08 L234 binds that combat

and depiction routing and it binds the market equally — nothing in the exchange layer prices a

person, and the ledger is legible only as evidence (compare the west_africa treatment at L2393-2396).

CH_09 — Ethiopia · no home · Trade 2 seed, Trade 9 first full exercise

ethiopia.md L983-984 is unambiguous: "Home-base trade content: NONE roots here." L711: "No trade

home base roots in the region; Trade-2 Mining seeds only, toward Ch 19."

(a) Ambient craft presence

"Copying is a profession, the debtera hold the reading-and-writing duties of the larger churches,

the monasteries are the keeping-houses, and the finished books travel" (ethiopia L702-706

[SRC_00254, pp. 103, 46]). Parchment plus the pigments and binders of that economy are named as

"this region's most distinctive worked material and the one the chapter's plot runs on" (L683-685).

cradle — "the first time in the arc that WRITING SOMETHING is the win condition of a fight"

(T0_Boss_Encounter_Registry @ BE_0009_S3; CH_09 L109, L135-138).

the Aksumite stele-raising are the region's engineering set-pieces and the Trade-8 Engineering

substrate seeds (echoes only — Trade 8's ancient home roots at Ch 27)" (ethiopia L620-622); the

material line is highland granite and basalt (L680-681).

then names what IS attested: "What the substrate DOES attest is the eating side rather than the

growing side, and it is enough to build a real gathering-and-consumption layer on" — an enormous

number of fasting days with the two weekly fasts on Wednesday and Friday, Pentateuchal slaughter

and bleeding, and a clean-and-unclean distinction governing what a household will and will not eat

(ethiopia L172-181 [SRC_00254, pp. 126, 114, 116]). CH_09 L76 names the gathering loop as "highland

foraging, the buna coffee-cherry harvest, and gold-adjacent prospecting," and CH09_B01 stages the

three-pour buna ceremony as the chapter's hook (CH_09 L114-118). **No page section routes any of

this to Trade 7**, whose single home is Ch 42 Haiti (T1_Trades_Master §3.7 L79). Classed AMBIENT,

debtera's training, whose curriculum is "sacred poetry, song, dance and rhythmical movement,

Scripture, and the law-book, in Ge'ez and Amharic" (L998-1002 [SRC_00254, p. 103]). "That is the

(c) Material and gather surfaces — and the gap

GAP. Zero T0_Gather_Node_Registry rows for ethiopia; zero T0_Flora_Registry rows. The page

compounds it honestly: "The region-filtered substrate contains NO ethnobotany, NO herbal

pharmacopoeia, and NO agricultural record for these highlands… the Ethiopian highlands are one of the

world's crop-domestication centres and the page says so nowhere, because nothing in the processed

corpus attests it. Phillipson and Pankhurst are the Section-16 acquisitions that close it"

(ethiopia L163-170). So this chapter's gather layer is blocked at the SOURCE tier, not only the

registry tier — a materially different gap from CH_08's.

PROPOSED gather-surface candidates — NOT APPLIED:

Every one of these is a class, not a species: the page mints no cultivar and no medicinal plant "until

the Section-16 acquisitions land" (L185-187), and this table respects that. **No herbal gather

candidate is proposed at all**, because proposing one would be exactly the import the page refuses.

region has been living with for a very long time" (L705-709). A vendor system here that treats

manuscripts as ordinary stock would contradict the chapter.

(e) Quest-seed hooks (READ-ONLY)

CH_09 carries ZERO trade-anchored quest-seed rows — SEED_0040 to SEED_0046 all have empty

(rift_valley L855-861). That routing is the finding — the pigment lane is a Trade-9 feeder, and

read. Named so no lane routes n/um healing into Trade 4.

(c) Material and gather surfaces — and the gap

GAP. Zero T0_Gather_Node_Registry rows for rift_valley; zero T0_Flora_Registry rows; **and

zero T0_Trade_Good rows — the only region in this slice half with none.** That triple-zero is

correct in one direction and a gap in the other: S9 rules "Trade goods, routes, currency, markets:

none at region scale. No trade home base roots here, no market is staged, and the region's economy in

the fiction is what a valley provides directly" (rift_valley L619-621). The trade-good absence is

therefore CANON-CORRECT and should be recorded as a deliberate zero, not filled. The gather

absence is a real gap: the spine names three gathering surfaces and the page says two of them are

buildable now (L866-869).

Deliberately NOT proposed: the arrow-poison botanical. The page rules it out in terms — "its

content is an acquisition rather than a page section. Nothing is authored: no species, no preparation,

no application, no effect" (L849-852), and "the third waits on the acquisition, and the page does not

fill it with a plausible substitute" (L868-869). Proposing a candidate row for it would be exactly the

plausible substitute the page refuses. Toolstone is proposed as a class only, since "no

sourcing-geology claim — which outcrops supplied which toolstone, over what distances — is authored

here, because the corpus attests none" (L610-612).

(d) Vendor and exchange moments

None, and that is canon. rift_valley L619-622: no market is staged, no currency, no routes at

region scale, and "Blacksmithing and metallurgy are absent from every stratum this chapter plays."

Any vendor built here would contradict the page. The chapter's economy in play is direct provision —

what a valley gives — and the trade layer's only exchange is teaching, which the page frames as

relationship rather than purchase.

Ju|'hoansi de-flattening and to the protected-community staging in CH_10 L204.

CH_11 — Central Africa, Congo Basin · no home · the Trade-1 community-substrate node

central_africa_congo.md L1452-1453: "Home-base trade content: none roots here. Ch 11 is a substrate

chapter for two trades whose homes sit elsewhere in the arc, and the page states that plainly rather

than inventing a home."

Structural note that governs this whole brief. T1_Trades_Master §8.4 L258 names the Mbuti

net-hunting protocol as the canonical community-substrate trade-master exemplar for Trade 1, and

§11 L311 binds Trade-1 depiction discipline "at Ch 11 Ituri Mbuti substrate per CVD §14.3."

CH_11's own net-hunt beat (CH11_B02, L109-113) is where "vril [is felt] for the first time not as a

substance to be gathered but as the living field between beings." **So the Trade-1 ladder's

community-substrate half is anchored at CH_11 and its institutional home base one chapter later at

CH_12.** That two-node shape is canon and is the most important trade fact in this half of the slice.

a hunter reads the whole living net of the forest, a documented body of applied ecological

substrate whose home base is Ch 7 South India (the Ch 11 to Ch 40 plant-knowledge continuity

bridge, not a new home base)" (CH_11 L67). The page's Book-of-Trades entries are held at exactly the

strength the record supports: "medicinal — the twelve barks and the medicinal washes above, cited to

Fang practice and never transferred to the Mbuti or Baka; ritual — myan, abomenzan, and the eboga

bush; food — wild fruit trees kept near the village (asas, nzina, and tom), forest mushrooms, nuts,

berries, honey…; toxic — nothing attested on this shelf, recorded as an absence rather than filled"

(central_africa_congo L200-206).

eboga item is gatherable, craftable, purchasable, or consumable by the player-character at any tier,

it is not a herbalism recipe, and the Trade-4 unlock path in this region does not run through it.

What the player may do with it is carry and prepare what the elders ask for at the vigil"

(L212-215). Any Trade-4 presence here that touched iboga would be a hard-line breach.

cross-node symmetry: the Trade-10 home rooted at CH_08 is a sea-and-monsoon craft; CH_11's is a

river-and-net craft, and the page keeps them distinct rather than generalising one onto the other.

(b) Teachers canon names

keeps the Baka and Mbuti material strictly separate (L73-82).

(L292-297).

(c) Material and gather surfaces — and the gap

GAP. Zero T0_Gather_Node_Registry rows for central_africa_congo; zero T0_Flora_Registry

rows. Both are pure registry gaps here — the page carries a real gather list with a real property law

attached (L1483-1486), which makes this the second-strongest unrowed gather substrate in the slice

half after CH_08.

The honesty note that must ride with any proposal: the honeyguide mutualism itself "returns nothing

on a region-filtered probe… So no honeyguide behaviour, call, or protocol is authored here, and the

Trade-1 seed stays at the level the spine states" (L292-296). The honey gather is attested; the

guiding-bird protocol is not.

acquisition" (L1458) and are cited to Fang practice specifically, never transferable to the Mbuti or

Baka (L201-202).

(d) Vendor and exchange moments — the arc's clearest non-market economy

This is the design-load-bearing S9 in the slice half and the page states the constraint outright:

in marriage transactions and the ceremonial payments that follow, and the economy was essentially

non-market: markets established in the colonial period never flourished, and the market at one

village was defunct six years after its founding, with the household unit within the village family

virtually self-sufficient" (L1000-1005 [SRC_00179, p. 149]).

"usually by barter or, in the Cameroons, by a form of ceremonial exchange called bilaba"

(L996-998).

TG_0034 iron_spear_point — the last with the registry's own note that it is "currency shaped as a

weapon… a trade good AND an exchange form, and the row is deliberately on the goods side because

bikuela, not iron, is the ceremonial currency."

copal the coast sells to the European trader are the same commodities the Free State quota system

industrialized inland" (L1010-1013). A vendor layer here should let the player see that seam, not

smooth it.

The learning register — the finding worth carrying forward

"Knowledge here is not purchased, unlocked by dialogue tree, or granted for a favour… this region's

trade unlock is PARTICIPATION: the player who takes a place in the work is taught, and the player who

asks to be taught is not answered in the way they expect. That is a mechanic, a care posture, and an

accurate rendering of the record all at once" (L1472-1481). This is the community-substrate register

of §8.4 rendered as a mechanic, and it is the single most transferable trade design in the slice half.

rubber, not ore, and is apparatus not trade); no alchemical tradition; no foodway craft routed to

Trade 7; and the region's script row BAKA_MBUTI_FOREST_SIGN is explicitly "a pre-writing

oral-not-script substrate deliberately outside the Thread-17 script run" (CH_11 L254), so it is

language substrate and not a Trade-9 surface.

as AMBIENT rather than SEED for that reason.

CH_12 — West Africa · TRADE_01 ancient home · FULL DEPTH

The law. T0_Trade_Registry @ TRADE_01: `ancient_home_chapter Ch_12 · ancient_home_region

W_Africa · home_base_upgrade_ceiling field_infrastructure · compound_membership none_field`.

T1_Trades_Master §3.1 L55 pins it; §7.1 L226 gives the infrastructure shape — "trade master NPCs at

home base chapters, regional familiar populations… and field mechanics for cross-species

coordination." west_africa.md L3211-3216 states it at page grain: "Trade 1 takes its ANCIENT home

base here, at ouidah_python_temple, under Priestess Senami (CHAR_0089), at beat CH12_B05 and scene

SC_CH12_temple_serpents_fed. It is the first trade home the arc roots in a sacred site rather than a

workshop."

The region's own substrate, which is what the depth law asks for. The page grounds the home in

the region's documented human-animal practice, not in a generic. The grounding line is the covenant:

"it was human beings who broke the ancient covenant at Ile-Ife, leading to the separation of humans

from the rest of creation… animals here are not a bestiary, they are a broken relationship. TRADE_01

Animal Communication takes its ancient home base at Ouidah because the region is where the tradition

itself says the talking stopped, and the trade is the beginning of an apology rather than a power"

(west_africa L462-468 [SRC_00168, p. 28]). **That is the trade's thesis and it is attested, not

authored.** Substrate is thick here; no thin-substrate finding is owed for CH_12.

(a) Ambient craft presence

— Ghenu, his mother, his sister Gudjo, the dangbe killed in ignorance, the monkey Zinhu who

identified the wrong, the two chickens at the serpent's grave, the small house built over the burial

place from which the worship of Dangbe descends (L3218-3226 [SRC_00252, pp. 241-242]) — with the

ethnographer's own correction adopted wholesale: the dangbe holds its place "because it is the

tohwiyo of the powerful royal sib of the old Kingdom of Peda, which accounts for the many rites

early travellers observed but did not explain" (L3226-3230).

the animal setting the pace"; the temple is protected terrain where "no combat verb resolves…, no

guardian-python record is cited for the Ibibio and explicitly not transferred to the Fon.

replaces smoking it out"; meet CR_0086/CR_0087 pangolins as a non-combat encounter "whose only

cooperative rotation — the whole forge converts one member's iron, he sells and keeps the proceeds,

then works for the others until his turn returns [SRC_00252, p. 119] — "a crafting-queue mechanic

with a social cost, documented rather than designed." Plus the Ile-Ife lost-wax bench (model,

invest, burn out, pour, break out, finish) taught by Olabisi (CHAR_0093), and the Fon asen bench

map and the shrine map are the same map (Olosa of the lagoon, Olokun of the sea) [SRC_00270]; and

the trap line is "a row of stakes set across a river with a basket fastened to each… checked from a

worker who sold his loom's product without authorisation drawing "loud objection and a fine," with

appliqué pattern ownership "jealously observed" [SRC_00252, pp. 74-75, 119]. **"Enforced authorship

the §8.4 sense, carried by the tradition rather than by an NPC.

(c) Material and gather surfaces — and the gap

GAP. Zero T0_Gather_Node_Registry rows for west_africa; zero T0_Flora_Registry rows. The

page nonetheless supplies the most literally-specified gather list in the slice half, because the

Care binding read in full, per the mandate. The page renders at ELEVATED and states the register

as a registry reading rather than a mood (L46-56): four distinct classes of living community stand on

this ground at once; two of the page's largest sources carry nineteenth-century race-science in their

editorial apparatus; and "the chapter's antagonist is an industrial machine for erasing exactly these

peoples' record — so the difference between weight and harm is decided line by line." The naming

discipline is the operative one: "where a source attests a thing only by description, this page

carries it descriptively and takes a Section-16 acquisition entry rather than supplying an unattested

vernacular word" (L27-31). **Every trade surface below obeys that: no vernacular plant name is minted,

and nothing here routes combat, extraction or acquisition through the /Xam, ǂKhomani, Gǀwi, Griqua,

amaZulu, Shona or Cape freed-slave communities** (CH_13 L226).

The chapter's arc coherence check, which the mandate asks for explicitly: CH_13's spine centre of

gravity is the evidence-journal (CH13_B01, HL_0070) and the §5.5 embedding fork (FORK_CH13_A), whose

corrosive branch is "learn how the extraction works, and file the method away" (CH_13 L187). The page

routes Trade 2 to exactly that: "the moral content is that the player learns how it works, which is

exactly what the corrosive direction files away" (south_africa L766-768). **The Trade-2 presence at

CH_13 is therefore not decoration — it is the mechanical body of the chapter's integrity fork.** That

is the coherence the care tier demands, and it is already canon.

(a) Ambient craft presence

Witwatersrand and Kimberley workings deepen the extraction substrate ahead of the Ch 14 seed and the

Ch 19 home. The substrate this region contributes is the industrial one — reef, pipe, stamp,

compound" (south_africa L765-768; CH_13 L259, L283). Note the ladder shape: CH_13 industrial

substrate → Ch 14 Nubia tier-seed → Ch 19 Persia home (T1_Trades_Master §3.2 L59).

this region and it is a good one, because it is a gathering item whose use is a procedure rather than

a stat: gathered on the fynbos and kloof slopes, it is thrown to calm, rubbed to settle, and burned

to clear. That is a three-verb consumable grounded in the tradition's own record rather than a potion

invented for a slot" (L234-238; S14 L769-770). This is the cleanest single trade artefact in the

slice half.

authorship theme rendered as a craft.

(c) Material and gather surfaces — and the gap

GAP. Zero T0_Gather_Node_Registry rows for south_africa; zero T0_Flora_Registry rows. The

page's own honest gap compounds it: "The corpus holds no ethnobotanical study of this region, so

beyond those three the page carries the flora by description and by ecological class and mints no

vernacular plant names at all" (L239-243).

Deliberately NOT proposed: any vernacular-named plant beyond the three the archive itself names

(buchu, tsamma, and the descriptively-attested ǃkuerriten-ǃkuerriten at L231-233), per the naming

discipline at L239-243. And no Witwatersrand or Kimberley yield of any kind — S9 rules it: the

reef and the pipe are "the reason the mine exists rather than as loot" (L586-587), and TG_0043's own

note reads "the Witwatersrand reef is deliberately NOT a good and NOT a drop." A gather node on the

reef would invert the chapter.

And the ochre node carries a care condition that must ride with it: TG_0038's registry note reads

"the Thread-22 sacred-stone weight sits on a GATHERING item rather than on a treasure… so this good is

gathered, ground, stored and used, and is never loot." The gather node is the correct home for the

Thread-22 weight; a drop table is not.

economic argument, and it closes the loop opened by TG_0023 at CH_08** — the same gold, in the same

Indian-Ocean network, seen from the producing end.

Six rows — the densest trade-good coverage in the slice half.

CH13_B08 stages the §5.5 embedding at cape_colony_port through Maria Booysen's mission-interpreter

introductions (CH_13 L143-147), and the fork's care note binds: the embedding "routes near the

colonial apparatus, never through the /Xam, Griqua, amaZulu, or freed-slave communities, who are the

victims of the extraction and never cast as perpetrators" (CH_13 L189). A vendor system at the port

must not make the freed-slave community a shopfront.

Findings for the director

F1 — The slice half carries BOTH of the arc's non-compound field trades' ancient homes.

T1_Trades_Master §7 L222 names exactly two trades that "operate outside the compound architecture…

through relational and field mechanics" — Trade 1 and Trade 10 — and both root their ancient homes in

this half (CH_08 and CH_12; T0_Trade_Registry home_base_upgrade_ceiling field_infrastructure on

TRADE_01). Consequence for the build: neither home base is a workshop, so the first two returnable

"benches" the player earns in the whole game are a boat and a temple. west_africa.md L3212-3213

already says it — "the first trade home the arc roots in a sacred site rather than a workshop." The

compound architecture (§6) does not appear anywhere in CH_08-13, and no lane should expect it to.

F2 — The Trade-1 ladder is a TWO-NODE shape, and only one node is rowed as its home. §8.4 L258

makes the Mbuti net-hunting protocol the canonical community-substrate exemplar for Trade 1 and §11

L311 binds the discipline "at Ch 11 Ituri Mbuti substrate," while the home base is CH_12. The

community-substrate half therefore lands one chapter *before* the institutional home. SEED_0058's own

title already names the shape ("a partnership that arrives one chapter before its home"). This is

coherent, not a defect — but it means a Trade-1 build that starts at CH_12 will miss the register

§8.4 says the trade is anchored by.

F3 — GATHER: zero rows across all six regions, and the flora registry blocks the fix.

T0_Gather_Node_Registry has 24 rows covering only flores_island / bali / sumatra_java / angkor_khmer.

T0_Flora_Registry likewise covers only those four, so **a flora_gather row for any of these six

regions has no yields_ref target to resolve today** — the flora registry must be extended before the

gather registry can be. T0_Creature_Roster DOES cover all six (7-20 rows each), so fauna- and

marine-yield nodes could resolve their FK now. Recommended order if the director takes this up: flora

rows first for the four regions with the strongest cited plant substrate (swahili_coast, west_africa,

central_africa_congo, south_africa), then gather nodes. Two regions must NOT be force-filled:

ethiopia (the corpus attests no ethnobotany at all — ethiopia L163-170) and rift_valley (the

arrow-poison botanical "waits on the acquisition, and the page does not fill it with a plausible

substitute" — rift_valley L868-869).

F4 — RECIPE: zero rows for all six regions. T0_Recipe has 16 rows; region_availability is

populated on exactly one (south_india) and chapter_gate_min runs CH_07 ×3 and CH_27 ×1. The whole

African arc has no recipe coverage. Two named craft artefacts in this slice half are recipe-shaped and

fully cited today and would be the honest first rows if the recipe seat wants them: **buchu's three

verbs** (thrown to calm, rubbed to settle, burned to clear — south_africa L234-238) and the

Swahili coir-and-stitch hull chain (palm → fibre → cord → hull — swahili_coast L200-208,

L1180-1187). Neither is minted here.

F5 — TRADE_GOOD: rift_valley's zero is CANON-CORRECT and should be recorded as a deliberate zero.

Five of six regions carry rows (swahili_coast 5, ethiopia 3, central_africa_congo 4, west_africa 3,

south_africa 6); rift_valley has none, and rift_valley.md L619-622 rules it: "Trade goods, routes,

currency, markets: none at region scale… Blacksmithing and metallurgy are absent from every stratum

this chapter plays." Recommend the registry seat annotate the zero rather than leave it looking like

an unfinished region.

F6 — Possible quest-seed anchor mismatch at SEED_0050 (CH_10). The row is

trade_anchor TRADE_04 and its title carries two lanes: "a pharmacopoeia taught standing next to its

keeper, and the pigment that travels out of this valley." The page routes the pigment lane

explicitly to Trade 9, not Trade 4 — "Pigment-craft is not one of the ten rowed trades and this page

mints no eleventh… the substrate's honest consumer is Trade 9 Inscription" (rift_valley L855-858).

Flagged only; the quest-seeds seat owns the row and this lane did not touch it.

F7 — CH_09 has ZERO trade-anchored quest seeds, and it is the arc's first full Trade-9 exercise.

SEED_0040 through SEED_0046 all carry empty trade_anchor, yet ethiopia.md L990-996 calls the

region "the arc's first FULL exercise of the trade and its most important pre-home node," with three

inscription surfaces stacking and BE_0009_S3 being "the first time in the arc that WRITING SOMETHING

is the win condition of a fight." SEED_0040 is that content, unanchored. This is the largest

trade/quest-seed mismatch in the slice half.

**F8 — Two AMBIENT surfaces are large enough that the director may want them routed, and neither is

this lane's to route. (i) CH_09's foodway layer** — the page states outright that the attested

"eating side" is "enough to build a real gathering-and-consumption layer on" (ethiopia L172-181), and

the buna three-pour ceremony is the chapter's hook beat, yet Trade 7 is single-home at Ch 42 Haiti

(§3.7 L79) so nothing routes it. (ii) CH_13's Great Zimbabwe dry-stone — the chapter's named

engineering set-piece (CH_13 L73) with no Trade-8 routing, and correctly so, since the monument rows

are hard_blocked and verbless. Both are recorded as AMBIENT rather than asserted as presence.

**F9 — The goldweight metrology is spine canon with a positively-controlled zero on the shelf, and it

touches a trade surface.** west_africa.md L2229-2240 records the search: goldweight, goldweights,

gold weight, gold dust, abrammuo, mrammuo, brass weight, brass weights — "zero chunks on all eight

across all thirty-four sources," with a clean control, and no Garrard volume on the shelf. CH_12 L167

carries the same declaration in the spine beat. Consequence for this lane: the **goldweight assay

stock** gather candidate in the CH_12 table is proposed as a *material* only; **no weight vocabulary,

no weight-shape set and no metrology content is proposed**, and none should be authored until Garrard

lands. TG_0035's own note says the same.

**F10 — The D-CAST reconciliation touches the only trade master in the slice half who becomes a

companion.** CH_08 L323 records that the ratified D-CAST ruling makes Nakhoda Binti Hassan an

invested_sticky ship-keeper present Ch 8→65, while the CH_08 entry still carries the pre-ruling

recurring-NPC model in four places, and that the ratified card ties the signing to the ship acquired

on this coast while the spine holds the mtepe strictly opt-in and non-gating. **The trade-side

constraint that falls out of it, stated so the reconciliation pass does not have to re-derive it: the

Trade-10 bench must remain returnable whether or not Binti Hassan is aboard and whether or not the

hull is ever owned** — otherwise the arc's first returnable trade home becomes gated on a companion

and a vehicle, which contradicts CH_08 L268 and T1_Trades_Master §10.5 L307. Not applied; a finding.

F11 — Care conditions that must ride with any downstream trade application in this slice half.

(i) HL_0007 at CH_11: no eboga item is gatherable, craftable, purchasable or consumable at any

tier, and "the Trade-4 unlock path in this region does not run through it"

(central_africa_congo L212-215). (ii) CH_12's Atlantic layer: nothing in a vendor system prices a

person or gives the trade a market entry (west_africa L2392-2396). (iii) CH_13's reef: the

Witwatersrand is "the reason the mine exists rather than as loot" and is neither a good nor a drop

(south_africa L586-587; TG_0043 note). (iv) CH_13's ochre: the Thread-22 weight sits on a

*gathering* item and never on loot (TG_0038 note). (v) CH_12's temple: no combat verb resolves

inside ouidah_python_temple and no quest state can make it a battleground (west_africa L3240-3242) —

which includes any trade-driven state.
