V1.1 INITIAL RELEASE NOTE

This first release implements Coverage Object 06 in the canonical sixty-spine
World Coverage Queue. It follows the West African–Sahelian human-geographic
coordinate from planetary and geological substrate through Pleistocene
occupation, Holocene pottery, food production, pastoral and fishing systems,
iron working, Nok material worlds, clustered urbanism, Ghana/Wagadu, Mali,
Songhai, Kanem–Bornu, plural Hausa states, Fulani pastoral and scholarly
networks, Atlantic and trans-Saharan systems, colonial conquest, independence,
regional integration, contemporary conflict, climate stress, digital systems
and observed AI-policy formation at the cut-off.

The parent World clock remains frozen at 28 July 2026. Publications or events
after that instant are outside this release even when they concern earlier
history.

==============================================================================
0. REGIONAL ARCHITECTURAL STATEMENT
==============================================================================

THIS IS NOT THE HISTORY OF ONE TIMELESS “WEST AFRICAN” OR “SAHELIAN
CIVILISATION.”

THIS IS NOT A SUCCESSION LIST IN WHICH NOK “BECOMES” GHANA, GHANA “BECOMES”
MALI, MALI “BECOMES” SONGHAI, OR SONGHAI “BECOMES” MODERN STATES.

THIS IS NOT PERMISSION TO PROJECT COLONIAL OR PRESENT-DAY BORDERS INTO DEEP
TIME.

The coordinate changes through:

ancient craton, basins, rivers, plateaux and changing Lake Chad
-> repeated Pleistocene humid/arid cycles and human occupation
-> hunter-gatherer, fisher and plant-management worlds
-> early pottery, grinding, storage and intensified wild-grain use
-> pastoral, millet, rice, cowpea, yam and mixed food systems
-> iron-production and terracotta-making communities
-> settlement clusters, towns and cities without one required state form
-> riverine, savanna, forest-edge and trans-Saharan exchange
-> Wagadu, Takrur, Mali, Songhai, Kanem–Bornu and many other polities
-> Hausa cities, scholarly networks, pastoral mobility and Fulani states
-> Atlantic commerce, enslavement, firearms and crop transfers
-> nineteenth-century reform, conquest, resistance and colonial rule
-> territorial states, decolonisation and regional institutions
-> urban, mobile-connected, climate-stressed and AI-planning systems

Geographic continuity is not biological, linguistic, ethnic, religious,
material-cultural or political continuity.

ONTOLOGICAL GUARDRAILS

• “West Africa” and “Sahel” are analytical human-geographic coordinates.
They are not actors and have no single lifecycle.

• NOK is an archaeological/material-cultural horizon identified through
pottery, terracotta, settlement, subsistence and metallurgy. It is not
serialized as one ethnicity, language, capital or kingdom.

• GHANA in medieval Arabic sources is a royal title and polity conventionally
called the Ghana Empire; WAGADU is the name carried in Soninke/Mande oral
traditions. Neither is the modern Republic of Ghana.

• KOUMBI SALEH is a major medieval town. Its equation with al-Bakri’s royal
capital is plausible but unproven; the missing royal town and lack of an
identifying inscription remain explicit.

• The often-repeated “Almoravid conquest of Ghana in 1076” lacks unambiguous
contemporary textual or archaeological proof and is not a settled event.

• MALI EMPIRE is not the modern Republic of Mali. Manden oral histories,
Arabic accounts, manuscripts and archaeology remain separately typed.

• SONGHAI language communities, river populations, Gao polities, Sonni and
Askia dynasties, imperial institutions and later Dendi states are not one
timeless entity.

• KANEM and BORNU are related but changing Lake Chad state systems. A moving
centre, dynastic continuity and later political memory do not erase the
populations governed, raided, enslaved or incorporated.

• HAUSA is a language and broad cultural field; Kano, Katsina, Zazzau, Gobir,
Daura, Rano, Biram and other states possess distinct clocks. The surviving
Kano Chronicle is a late-nineteenth-century composition drawing on older
oral and written materials, not a contemporary tenth-century annal.

• FULANI, FULA, FULƁE and PEUL name overlapping language and identity fields.
Pastoral dispersal, town residence, clerical affiliation, reform movements,
jihads and state formation require separate records.

• Islamisation, Arabic literacy, Ajami writing, commercial law, political
allegiance and conquest are distinct and uneven processes.

• Oral tradition is evidence, not an inferior placeholder for text; it is
nevertheless dated, attributed and compared rather than converted silently
into exact event chronology.

• Enslavement and coerced movement are recorded as coercive systems, not
neutral “trade goods.”

  1. GEOGRAPHIC SCOPE, OVERLAPS AND EXCLUSIONS

CORE HUMAN-GEOGRAPHIC COORDINATE

the Senegal, Gambia, Falémé, Niger, Bani, Volta, Komadugu–Yobe and Chari–
Logone river systems;
the Inland Niger Delta and Niger Bend;
the western and central Sahel, Sudanian savannas and forest–savanna mosaic;
the Senegal valley, Senegambia, Manden, Massina, Mossi plateau, Hausaland
and the Lake Chad basin;
present-day Senegal, The Gambia, Mali, Burkina Faso, Niger, northern Guinea,
northern Côte d’Ivoire, northern Ghana, northern Togo and Benin, northern
Nigeria and Chad as geographic aids only.

CONTROLLED OVERLAPS

OBJECT 05 — SAHARA AND MAGHREB
Mauritania, Saharan pastoralism, Awdaghost, Tichitt, Walata/Oualata,
Tuwat, Sijilmasa, Taghaza, caravan carriers, Amazigh/Tuareg communities
and coerced human movement are shared. Sahara–Maghreb detail remains in
Object 05.

OBJECT 07 — WEST AFRICAN FOREST ZONE
Kintampo, Nok’s southern interfaces, Bono, Akan/Asante, Yoruba/Ife, Benin,
Dahomey, Atlantic ports, kola and forest gold enter only where they alter
Sahelian systems. Their full histories retain Object 07.

OBJECT 08 — CENTRAL AFRICA / CONGO BASIN
Cameroon Grassfields, Adamawa, Chadic and Bantu interfaces are connector
problems. Shum Laka is used only for the deep-population caution it supplies.

OBJECT 03 — NILE VALLEY / NORTHEAST AFRICAN CONNECTORS
Wadai, Darfur, eastern Chad, pilgrimage and trans-Saharan routes overlap.

ATLANTIC, ISLAMIC, COLONIAL AND GLOBAL CONNECTORS
long-distance systems enter only with a carrier, direction, interval,
evidence and confidence value.

EXCLUSIONS

Modern nationality is not assigned to precolonial people.
Language families are not dated from archaeological pottery alone.
Present state territory is not legal ownership of all earlier entities.
Future plans are not observed history.

Core primitives:
ENTITY | TIME | SPACE | STATE | EVENT_PROCESS | RELATIONSHIP | PART_WHOLE |
FLOW | LINEAGE | DEPENDENCY | HOST | EVIDENCE

Core invariants:

01 LOCAL TRUTH MUST SURVIVE GLOBAL ALIGNMENT.
02 UNKNOWN MUST REMAIN UNKNOWN.
03 ASSERTION MUST NOT BE MISTAKEN FOR FACT.
04 ENTITY IDENTITY MUST SURVIVE STATE CHANGE.
05 TIME RESOLUTION MUST MATCH EVIDENCE.
06 PHYSICAL LOCATION IS NOT LEGAL OWNERSHIP.
07 EXISTENCE IS NOT OPERATION.
08 INVENTION IS NOT MASS CAPABILITY.
09 PHYSICAL HOST IS NOT LOGICAL IDENTITY.
10 HISTORICAL ANCESTRY IS NOT STRUCTURAL DEPENDENCY ANCESTRY.
11 ONE LABEL MAY HIDE MANY ENTITIES.
12 CIVILISATION REMAINS NESTED INSIDE PLANETARY SUBSTRATE.

West Africa–Sahel implementation:

• a stone-tool assemblage is not a named people;
• a crop’s domestication region is not a single inventor community;
• pottery or terracotta is not a language family;
• iron working does not itself prove state centralisation;
• a merchant quarter is not the whole city;
• royal tradition, dynastic list and excavated sequence retain distinct clocks;
• a pilgrimage displays connections but does not begin them;
• a jihad may create institutions while also producing war, enslavement and
coerced incorporation;
• colonial boundaries are imposed political geometries, not recovered ancient
borders;
• national AI strategy is a policy state, not demonstrated universal capability.

==============================================================================
3B. CIVILISATION CAT SCAN V1.1 BINDING

The chronology can be traversed in ten modes:

MODE 01 — LONGITUDINAL
Follow one entity, function, place or dependency through time.

MODE 02 — CROSS-SECTIONAL
Cut one W-band across this and other regional spines.

MODE 03 — STRUCTURAL
Read entities, part-whole relations, functions, institutions and flows.

MODE 04 — DEPENDENCY/HOST
Identify what carries food, water, memory, power, exchange and computation.

MODE 05 — PRESSURE FIELD
Test climate, disease, coercion, ecology, inequality and external shocks.

MODE 06 — OUROBOROS/FEEDBACK
Locate reinforcing or balancing loops and their excluded costs.

MODE 07 — GENOME/PHENOTYPE
Separate persistent operating rules from visible implementations.

MODE 08 — CONNECTOR/TRANSMISSION
Follow evidenced people, genes, livestock, crops, metals, goods, beliefs,
scripts, institutions, force, capital, energy, data or technology.

MODE 09 — SIMULATION/COUNTERFACTUAL
Change an explicit dependency or pressure without rewriting observed history.

MODE 10 — PORTABILITY/FISSION
Ask which functions can move, which substrates remain indispensable and
where a daughter system would become structurally independent.

No single lifecycle score is assigned to the whole coordinate.

==============================================================================
3C. GENOME, PRESSURE FIELD AND OUROBOROS V1.1 BINDING

CIVILISATIONAL GENOME stores recurrent operating rules, not biological genes:

seasonal mobility and transhumance;
river-flood adaptation and floodplain cultivation;
millet, sorghum, rice, cowpea, yam and mixed food portfolios;
iron, leather, cloth, pottery and specialised craft transmission;
kinship, household, age-grade, lineage and village coordination;
market, caravan, river and diaspora brokerage;
royal redistribution, tribute, taxation and provincial delegation;
scholarly, clerical, manuscript, oral and Ajami memory;
military capture, enslavement and labour extraction;
colonial cash-crop, rail, tax and forced-labour systems;
postcolonial centralisation, military rule and regional integration;
mobile money, platform, satellite, cable, cloud and AI-policy dependence.

PRESSURE_FIELD[] may include:

monsoon shift | aridification | drought | flood | locust | crop disease |
livestock disease | epidemic | food price | taxation | tribute |
forced labour | enslavement | war | raid | occupation | border closure |
displacement | unemployment | debt | mining rent | legitimacy |
information control | climate heating | infrastructure failure

Candidate OUROBOROS[] structures for evidence testing:

rainfall–pasture–mobility–conflict/negotiation;
floodplain surplus–market density–craft specialisation–urban demand;
caravan protection–tax revenue–military capacity–route control;
cavalry/firearms–capture–enslaved labour–state expansion;
colonial tax–cash crop/forced labour–resistance–repression;
drought–herd/crop loss–migration–resource pressure;
insecurity–military spending–civilian harm–recruitment/legitimacy loss;
extraction rent–centralisation–weak diversification–rent dependence;
mobile access–market coordination–data capture–platform dependence.

These are hypotheses until instantiated by evidence.

==============================================================================
3D. PORTABLE CIVILISATION, SIMULATION AND FISSION V1.1 BINDING

PORTABILITY LEVELS

P0 place-bound
P1 knowledge-portable
P2 institution-portable
P3 infrastructure-portable
P4 materially closed and reproducible
P5 independently self-maintaining

Pastoral knowledge, merchant diasporas, oral epics, manuscripts, legal schools,
craft guilds, languages, currencies and digital services demonstrate partial
portability. They do not demonstrate closed ecological reproduction.

At the cut-off the coordinate’s interacting state systems remain H1 —
EARTH-DEPENDENT CIVILISATION, crosswalking to PLANETARY_DEPENDENT. Food,
water, health, settlement and energy remain biosphere- and human-host-dependent;
telecommunications, finance, satellite navigation, cloud services and AI add
planetary infrastructure dependencies.

Simulation and fission outputs must be labelled MODELLED, HYPOTHETICAL or
UNKNOWN. No forecast is serialized as observed chronology.

==============================================================================
4. COMPRESSED REGIONAL SPINE
==============================================================================

deep time West African Craton, sedimentary basins, plateaux, river
systems and Lake Chad create the changing substrate.
Pleistocene discontinuously preserved stone-tool records show repeated
human occupation; the record is sparse, not an empty region.
62–25 ka Tiémassas preserves repeated Middle Stone Age coastal
occupations; other regions maintain distinct tool traditions.
16.3–11.7 ka Iho Eleru burial documents late-Pleistocene/early-Holocene
human diversity without proving a surviving archaic species.
before 9400 BCE Ounjougou pottery appears among hunter-gatherer/forager
systems during early-Holocene ecological change.
8000–3000 BCE fishing, gathering, pottery, mobility, herding and plant
management recombine across rivers, savannas and lake basins.
c.2500 BCE on pearl millet domestication and dispersal support increasingly
diverse food systems; rice, cowpea, yam and other crops have
separate, partly unresolved histories.
c.2200–400 BCE Tichitt-tradition settlements grow and contract as aridity
shifts; no automatic direct line to Wagadu is asserted.
c.1500 BCE–
early CE Nok material horizons include farming, terracotta and later
iron working; they do not form a demonstrated single kingdom.
first millennium
BCE–CE iron production expands unevenly; Jenné-jeno, Daima, Kissi
and other sites show plural settlement and craft trajectories.
c.250 BCE–
1400 CE Jenné-jeno and the Inland Niger Delta demonstrate clustered
urbanism without requiring palace-centred government.
c.700–1200 Gao, Tadmekka, Awdaghost, Takrur and Wagadu connect river,
savanna and Saharan systems through trade, Islam and politics.
c.1000–1400 Kanem and later Bornu develop around Lake Chad; Hausa cities
consolidate on distinct clocks.
c.1230s–1600s Mali grows through Manden coalitions, gold and river routes;
Songhai later builds an empire centred on Gao and Niger fleets.
1591 Saadian forces defeat Songhai at Tondibi; Arma/Pashalik and
Dendi successors continue rather than an empty “collapse.”
1500s–1800s Hausa, Bornu, Mossi, Jolof, Segu and many other systems trade,
fight, farm, produce and transmit knowledge.
1720s–1903 Fulani-led reform movements and states form in Futa Jallon,
Futa Toro, Sokoto, Adamawa, Massina and elsewhere, with
institution-building, warfare, enslavement and resistance.
1800s–1914 Atlantic and Saharan pressures intensify; African states and
coalitions resist French, British and German conquest.
1914–1945 conscription, forced labour, cash crops, wars, rail and
anticolonial resistance reshape colonial territories.
1945–1965 parties, unions, veterans and mass movements accelerate
decolonisation; territorial states become independent.
1960s–1990s nation-building, coups, civil wars, drought, ECOWAS and
structural adjustment transform state and household systems.
2000–2014 mobile connectivity expands while Boko Haram and Sahel wars
generate new military, humanitarian and border systems.
2014–2020 Ebola, climate extremes, urban protest, insurgency and
democratic transitions coexist with digital growth.
2020–2025 COVID-19 and coups alter institutions; AES forms and Mali,
Burkina Faso and Niger leave ECOWAS.
1 Jan–28 Jul
2026 conflict, displacement and food insecurity remain severe;
ECOWAS and AES coexist; national AI strategies move from
planning toward uneven implementation.

field system | storage | cuisine | market.

LONGITUDINAL PATH:
western Sahel domestication
-> Tilemsi/Tichitt
-> Kintampo/Nok and wider dispersal
-> urban provisioning
-> colonial and national dryland agriculture
-> climate-adapted breeding and food security.

FALSE CLAIM TO AVOID:
one crop does not identify one people or polity.

SCAN WASA.CAT.L03 — NOK

ENTITY:
archaeological horizon, not kingdom or ethnicity.

OBSERVED:
pottery from c.1500 BCE; dispersed settlements; pearl millet; terracotta
principally first millennium BCE; iron from approximately 700–500 BCE;
diagnostic horizon ends around the Common Era.

UNKNOWN:
language, self-name, political titles, capital, exact ritual meanings and
descendants of particular communities.

HERITAGE PRESSURE:
looting severs object from context and destroys graph edges.

SCAN WASA.CAT.L04 — WAGADU

EVIDENCE CHANNELS:
Arabic external texts | Soninke/Mande oral tradition | archaeology |
environmental and route reconstruction.

FUNCTIONS:
agricultural base, court, tribute, customs, cavalry, market protection and diplomacy.

DISALLOWED MERGES:
ancient Ghana != modern Ghana;

Manden coalitions and victory traditions, not one exact founding decree.

DEPENDENCIES:
gold, crops, river, cavalry, provincial alliance, merchant and caravan.

INFORMATION HOSTS:
epic performance, Arabic geography/travel, manuscript and archaeology.

MUSA 1324:
high-visibility connector that reveals, rather than creates, the network.

FISSION:
imperial contraction leaves Manden polities, lineages, cities and trade.

SCAN WASA.CAT.L06 — SONGHAI

ENTITY SEPARATION:
Songhay-speaking populations | early Gao polities | Sonni Empire |
Askia administration | Arma/Pashalik | Dendi successors.

CAPABILITIES:
Niger fleet, cavalry, taxation, provincial delegation, markets and scholarship.

FRACTURE:
succession conflict plus Saadian expedition and firearms at Tondibi.

NON-EXTINCTION:
loss of imperial centre is not disappearance of people, cities or knowledge.

SCAN WASA.CAT.L07 — KANEM–BORNU

HOST MOVEMENT:
Kanem/Njimi -> court displacement -> Bornu/Ngazargamu -> al-Kanemi centres.

PERSISTENCE:
mai/shehu authority, Lake Chad food base, cavalry, caravan and Islamic diplomacy.

STATE CHANGE:
Duguwa traditions -> Sayfawa/Sefuwa -> al-Kanemi; Rabih interruption;
colonial emirates retain limited titles.

PRESSURES:
lake ecology, Bulala conflict, succession, Sokoto jihad, route change,
colonial partition and modern insurgency.

SCAN WASA.CAT.L08 — HAUSA STATES

ENTITY SEPARATION:
Hausa language/culture | each city | each dynasty | merchant diaspora |
later Sokoto emirate.

SOURCE CONTROL:
Kano Chronicle combines oral and written material in a late-nineteenth-
century composition; early dates remain attributed.

FUNCTIONS:

SCAN WASA.CAT.L10 — COLONIAL EXTRACTION

HOSTS:
army, appointed chief, tax, forced labour, rail, road, port, cash crop,
school, map, census, currency and archive.

FEEDBACK:
tax -> labour/crop compulsion -> resistance/migration -> repression ->
greater administrative reach.

FISSION:
independence ends imperial sovereignty but inherits borders, corridors,
armies, legal forms, language hierarchies and commodity dependencies.

SCAN WASA.CAT.L11 — ECOWAS TO ECOWAS–AES

1975 GENOME:
economic integration and collective self-reliance.

LATER PHENOTYPE:
free movement, court, election diplomacy and military intervention.

PRESSURE:

15B. PRESSURE-FIELD MATRIX

TICHITT AGROPASTORAL SYSTEM
pressure: aridification
available moves: mobility, settlement contraction, crop/herd mix, river shift
lock-in: stone settlement and stored surplus
excluded cost: unequal access and displacement

INLAND NIGER CITY CLUSTER
pressure: flood variability and exchange interruption
available moves: settlement specialisation, seasonal mobility, food portfolio
lock-in: dense floodplain dependence
excluded cost: occupational and status inequality

WAGADU/MALI/SONGHAI IMPERIAL SYSTEMS
pressure: route shift, succession, frontier war and revenue loss
available moves: alliance, provincial delegation, route capture, taxation
lock-in: cavalry, court and long-distance revenue
excluded cost: tribute, warfare and enslavement

KANEM–BORNU
pressure: lake ecology, enemy displacement and caravan competition
available moves: move court, recover routes, federate, diplomatic trade
lock-in: cavalry and trans-Saharan supply
excluded cost: raiding and coerced labour

SOKOTO CALIPHATE
pressure: legitimacy, frontier war and provincial autonomy
available moves: scholarship, emirate delegation, ribat, tax and mediation
lock-in: cavalry/agrarian and enslaved-labour systems
excluded cost: capture, servitude and local dispossession

COLONIAL STATE
pressure: revenue target, war demand and resistance
available moves: tax, forced labour, appointed chief, rail and repression
lock-in: export corridor and racial/legal hierarchy
excluded cost: death, land/labour loss and structural dependency

CONTEMPORARY CENTRAL SAHEL
pressure: insurgency, displacement, food prices, climate and legitimacy
available moves: military partnership, decentralisation, negotiation,
social protection, regional coordination or repression
lock-in: weak fiscal base, commodity dependence and militarisation
excluded cost: civilian harm, closed politics and service loss

CONTEMPORARY COASTAL–SAHEL SYSTEM
pressure: urban jobs, debt, flood/heat, insecurity spillover and platform change
available moves: integration, infrastructure, diversification, education
and accountable digital/AI policy
lock-in: import energy/food, external finance/cloud and informal employment

15C. PORTABILITY/FISSION TEST

KNOWLEDGE-PORTABLE:
route memory, livestock care, seed selection, iron recipe, oral epic,
jurisprudence, Ajami, commercial practice, administrative procedure and software.

INSTITUTION-PORTABLE:
scholarly circle, merchant diaspora, pastoral access council, emirate,
party, payment service and AI research group if human/legal hosts exist.

PLACE-BOUND:
river flood, lake ecology, aquifer, ore body, farmland, dam, city fabric,
burial ground and heritage site.

NOT CLOSED:
no state or city can reproduce food, water, energy, advanced hardware,
population and biosphere independently of Earth and global supply systems.

FISSION RULE:
a renamed, conquered, independent or seceded state is not automatically
functionally independent; dependencies and local continuities must be tested.

15D. LIVE SUBSYSTEM STATE AT THE FROZEN CUT-OFF

SNAPSHOT INSTANT:
23:59 Asia/Singapore, 28 July 2026.

CAPABILITY:
STAGE 3 overall, with selected STAGE 4 network capabilities. Mobile money,
satellite observation, cloud services and AI-policy work do not make food,
energy, compute, security or institutional capacity uniformly planetary.

LIFECYCLE:
no single regional lifecycle. Urban and digital systems are in TAKEOFF or
CLIMB; several regional institutions are TRANSFORMING; conflict-affected
local systems range from DESCENT to partial RECOVERY.

BASEFLOOR:
FOOD ADEQUATE to CRITICAL, spatially unequal
WATER ADEQUATE to STRESSED
ENERGY STRESSED and highly unequal
SHELTER ADEQUATE to FRACTURED where displacement is severe
HEALTH ADEQUATE to STRESSED
SECURITY ADEQUATE to CRITICAL
ENVIRONMENT STRESSED
SOCIAL_STABILITY ADEQUATE to FRACTURED
KNOWLEDGE_CONTINUITY ADEQUATE to STRESSED in conflict zones
INFRASTRUCTURE ADEQUATE to STRESSED

CONTROL GEOMETRY:
HYBRID: constitutional states, military governments, local authorities,
customary and religious institutions, ECOWAS, AES, firms, platforms,
armed organisations and international actors exercise overlapping power.

MOTION VECTOR:
TRANSFORMING, ADAPTING and FRAGMENTING at the same time, depending on
subsystem and place.

HABITAT DEPENDENCE:
PLANETARY_DEPENDENT. Every polity remains dependent on Earth systems and
interregional food, energy, finance, logistics, communications and compute.

==============================================================================
17. EVIDENCE, ATTRIBUTION AND REVISION PROTOCOL
==============================================================================

EVIDENCE RULES

  1. A source proves only the claim and interval it supports.
  2. Ancient event, excavation, measurement, publication and heritage-
    inscription dates are different time objects.
  3. “Earliest” means earliest defensible evidence in this version and remains
    reviewable.
  4. A stone-tool assemblage cannot identify its maker’s ethnicity or language.
  5. Ancient DNA describes sampled people and modelled relationships; it does
    not independently name a culture, language or civilisation.
  6. Crop domestication, first preserved grain and mass dietary importance
    retain separate dates.
  7. Furnace, slag, iron object and proposed metallurgical invention are
    separate evidence claims.
  8. Nok, Kintampo, Tichitt and archaeological “traditions” remain material-
    cultural classifications unless independent evidence supports more.
  9. Oral tradition is attributed to performer/community, collection and
    transmission context; current wording is not silently back-dated.
  10. Medieval Arabic texts retain author, date, source distance and genre.
    External labels are not assumed to be local self-names.
  11. The Kano Chronicle and Timbuktu chronicles are source objects with their
    own composition histories.
  12. A modern state is not the successor-owner of every earlier polity in its
    present territory.
  13. Imperial “extent” distinguishes claim, raid, tribute, alliance, appointed
    official and sustained operational control.
  14. Enslavement, forced labour, conscription and displacement remain typed
    coercive flows.
  15. Colonial archives document administrative action and viewpoint, not a
    neutral total description of colonised people.
  16. Election, casualty, displacement, food-security and economic counts store
    release date and revision state.
  17. Government, armed-group, court, NGO and news claims remain attributed
    until independently corroborated.
  18. Strategy, target, scenario and forecast are not observed future events.

CONTROVERSY STATES

OPEN
legitimate competing interpretations with no decisive evidence.

BOUNDED
core fact secure; date, mechanism, scale or interpretation debated.

RESOLVED_FOR_VERSION
sufficient evidence for current serialization, still reviewable.

• Koumbi Saleh as Ghana’s capital: OPEN;
• Almoravid conquest of Ghana in 1076: REJECTED as settled fact;
• exact Kirina date/place and verbatim medieval Manden Charter: BOUNDED;
• early Kano ruler dates and Bayajidda event-history: OPEN;
• Amina’s exact reign and campaigns: OPEN;
• early Kanem chronology and girgam historicity: BOUNDED;
• exact current armed-group territorial control: live and date-sensitive.

REVISION TRIGGERS

• new secure radiometric dates or excavated contexts;
• ancient DNA with ethical provenance and adequate comparative sampling;
• archaeobotanical reassessment of crop status;
• new manuscript stemma, edition or oral-history documentation;
• revised casualty/displacement/food-security datasets;
• constitutional, treaty, membership or territorial-control change;
• verified national AI implementation data;
• any event after the cut-off requires a new version, not silent insertion.

MACHINE CHECKS

PASS chronology identifiers are unique and contiguous.
PASS every chronology record contains class, date status, zoom and entity type.
PASS every chronology record contains time, W-band and place.
PASS every chronology record contains entity and event/condition projections.
PASS every chronology record contains domain, evidence, confidence and sources.
PASS every cited WASA.S key resolves to one source-register definition.
PASS no source-register definition is orphaned.
PASS record class, date status, evidence and entity values use declared vocabularies.
PASS graph, connector and crosswalk identifiers are unique.
PASS the final observed event surface does not pass the frozen cut-off.
PASS plans and forecasts are typed separately from observations.
PASS disputed propositions retain explicit epistemic status.

INTEROPERABILITY

EMPTY known empty array or relationship set.
