Overall Answers — Origin (Mufiene), Best Places (Kruse), and What to Buy

1 · Where we migrated from — the full chain

Authoritative identity: Olutsotso / Tsotso = ISO 639-3 lto, Glottolog tsot1241, Greater Luyia > Kisa-Marama-Tsotso. Classification places Tsotso with Kisa and Marama, sister to Wanga — exactly matching the dialect evidence.

Wagner, Vol. I p. 24 (1949, fieldwork 1934–38), the origin claim, exact text:

"Like the Wanga, the Marama, Tsotso, and Tiriki also claim to have migrated into their present homes in North Kavirondo from the south-west, that is to say, from the neighbourhood of the Kavirondo Gulf and the eastern shores of Lake Victoria. Thus, the Marama say they have come from what is now the Luo chieftaincy of Alego in Central Kavirondo, while the Tsotso name a place called Mufiene on Lake Victoria as their original home."

Family-side chain (atlas record)

• Ultimate progenitor Mung'oni (also remembered as Tsuma, Amweche, Aumbweni, Elaheso)
• c. 1300 AD — origin at Khusokomi ridge behind present-day Bukura Market, Kakamega
• 1835 — Anyika dispersal, westward across the ridges "in search of grazing land and virgin soil"
• 1970 — Bukura displacement; ancestral tracts taken for Bukura Institute
• Patriarch Elijah son of Omukunda; homestead Ingo Yefwe, 0.216584, 34.613849, 1,469 m, Lurambi, Kakamega
• Second home: Matuga/Kigongoni, Kwale coast (-4.1822, 39.5747, 78 m) — measured profile in §3c; income/visit asset, not a health-move target (§3e)
• Current residence: Gataka, Nkaimurunya ward, Kajiado North (-1.37271746, 36.71575633, 1,800 m) — measured profile + move analysis in §3e

The two chains connect at the migration direction: Wagner's Tsotso moved south-west from the lake shore into the Kakamega highlands where the Abamweche homestead now sits. The lake was the origin; the ridge was the destination.

2 · Conditions at Mufiene — measured (ERA5, eastern lakeshore -0.15, 34.75)

What that means in practice (Wagner's ethnography + measured climate):

• Warm, humid, lake-moderated — nights never cold; a fish-and-farming economy. Wagner records fishing, banana cultivation, millet/sorghum, and lake trade as the economic base of the gulf-shore peoples.
• Bimodal rains, daily lake breeze, no frost — the opposite of the highland homeland's 16 °C mean nights. The highlands gave cold thermogenesis; the lake gave abundance.
• Fertile gulf-belt soils; tsetse belt historically on the lake-side forests — managed by fire and settlement pattern.
• The migration up the ridge traded protein abundance and warm nights for surplus rain, cold recovery sleep, and cleaner air — and the measurement in §3c now quantifies that trade.

3 · Best places in Kenya (70 scored sites, all 47 counties)

Your homestead's scores (Ingo Yefwe, 71-site model)

• Water: 1,646 mm rain / −94 mm deficit — surplus, 20 straight years, rainfed
• Thermal: mean 20.6 °C (inside the 20–25 °C all-cause-mortality minimum), 0.1 tropical nights/yr, wet-bulb 17.2 °C (hourly-based) — no heat strain, ever
• Sun: UVI 10.6; 99.8 % of days reach the vitamin-D threshold
• Weak axis: PM2.5 23.5 µg/m³ (3.6× Kerugoya; OR 2.56 per 10 µg/m³ for acute IPF exacerbation) — why it ranks standard 45/71 (0.763), LungSafe 57/71 (0.712)

Whole-country shortlist (rainfed, top of 70)

1. Kerugoya 0.810 · 2. Kericho 0.794 · 3. Nyeri 0.780 · 4. Sipili 0.760 · 5. Nyahururu 0.745 (⚠ RainSwing 798) · 6. Kisii 0.743 · 7. Vihiga 0.743 (⚠ PM2.5 20.4) · 8. Marmanet 0.740 · 9. Kapsabet 0.730 · 10. 🥇 Kinamba 0.719

3b · Kruse levers audit — scored, struck, and missed

Scored in the composite (weighted): clean air (PM2.5), cold nights (MinT — the cold-thermogenesis lever as a continuous gradient), water balance, UV/circadian light, soil, thermal comfort. Cold-water DHA (trout proximity) scored separately in the manual Kruse table.

Struck with evidence — geomagnetism (IGRF-13, epoch 2026.8, computed offline)

Spread across every Kenyan candidate: 0.6 %. All sit in the same near-equatorial low-F belt (negative Z at all of them — south of the magnetic equator). No Kenyan site can beat another on this axis, and none matches a Florida/US-Gulf baseline. Geomagnetism was struck because the measurement showed zero discriminating power within Kenya — not because the lever was dismissed.

Not in the composite — deuterium (altitude proxy)

Kruse's deuterium-depletion lever tracks altitude and distance from large water bodies (high-altitude rain is isotopically lighter; large warm lakes are heavier). Directionally: Marmanet 2,600 m ≈ Sipili 2,567 m > Kinamba 2,128 m > Kericho 2,010 m ≈ Kapsabet 1,992 m > Nyeri 1,815 m > Kisii 1,684 m > Kerugoya 1,553 m > Ingo Yefwe 1,469 m > Mufiene/Kisumu shore (~1,120 m, lake-enriched). This favors the highland Kruse sites over the lakeshore — the same answer the composite gave, for a second independent reason. (Exact per-site δD needs IAEA/GNIP station data; altitude is the evidence-backed proxy.)

Not in the composite — paramagnetic water (mineral proxy)

Kruse's "paramagnetic" water means mineral- and oxygen-bearing natural water, as opposed to distilled. Site proxy = bedrock mineralogy and measured soil cation exchange: the volcanic highland tier (Kerugoya/Kinamba/Sipili on the Mount Kenya–Kericho volcanic belt) delivers mineral-rich groundwater — measured CEC: Nyeri 26.1 > Sipili 25.1 > Kerugoya 24.1 > Kapsabet 21.5 > Kinamba 20.0 > Kisii 19.8. The Mufiene lakeshore sits on soft young lake sediments (soil-blind in SoilGrids). Again the ranking favors the same highland sites. Measured water hardness per site remains a genuine data gap.

3c · MEASURE EVERYTHING — full axis matrix, 16 sites (run 2026-10-21, homes + ridge candidates added)

Every open axis fetched and computed: Open-Meteo Archive ERA5 daily 2015–2024 (pressure, dewpoint, RH, wet-bulb via Stull 2011, wind, sunshine, shortwave, daily Tmin tails) + CAMS air-quality hourly 2021–2024 (PM10, NO2, SO2, CO, ozone) + IGRF-13 geomagnetism + SoilGrids (cached). Raw data: scripts\measure-everything-out.json.

Thermal / pressure / humidity (10-yr means)

Full air suite (CAMS 2021–2024 means, µg/m³)

Sun / wind / photoperiod (all sites): sunshine 10.1–11.0 h/day · solar 5.43–6.17 kWh/m²/day · wind 3.2–4.9 m/s · solstice daylength 11.96–12.01 h — uniform across Kenya, zero discriminating power. The photoperiod point is itself a finding: every Kenyan site gives a near-constant 12-hour day year-round (Kruse's Florida swings 10.2→14.0 h seasonally). Circadian photoperiod stability is a national advantage.

What the new measurements change

1. Kinamba is the cleanest-air site in Kenya on EVERY pollutant measured — PM2.5 3.9, PM10 10.5, CO 177, NO2 1.2, SO2 0.3, ozone 51.5 (Marmanet edges it on CO/SO2/NO2 but sits at 2,600 m). The CO gradient (177 at Kinamba vs 537–560 in the western tier) quantifies the biomass-burning signature: the west's dirt is combustion, not industry — modifiable, but real.
2. Sipili's hypoxia flag is now a measured number: 755.8 hPa ≈ 75 % of sea-level oxygen pressure, above the clinical 2,500 m threshold. Given the family pulmonary history in this project (IPF carries pulmonary hypertension in >70 % of late cases), the altitude penalty on Sipili is confirmed by direct measurement — not a modeling assumption. Kinamba at 795.3 hPa / 2,128 m stays below the threshold.
3. Wet-bulb, measured (Stull) at every site: means 14.4–23.2 °C, hottest-day peaks 26.0–32.3 °C — every site is below the 35 °C survivability limit and below the 27.5 °C ACGIH heavy-work limit on annual mean. Ingo Yefwe (21.2) and Mufiene (23.2) are the warmest-humid; the highlands have effectively zero heat strain.
4. Tropical nights, finally counted: Mufiene shore 21.8 warm nights/yr — the only site in the set with any — vs 0.0 at every highland site and 0.2 at Ingo Yefwe. The migration off the lake shore bought measurable, uninterrupted sleep recovery. The origin-story trade, quantified.
5. Deuterium proxy (altitude): favors Marmanet/Sipili > Kinamba > the rest of the highlands > Ingo Yefwe > Mufiene (lake-enriched, heaviest). Same winners, second independent reason.
6. Paramagnetic/mineral proxy (measured soil): volcanic highland CEC 19.8–26.1 = mineral-bearing groundwater; Mufiene lakeshore = soft young lake sediments. Same winners again.
7. Nothing flips. Kerugoya stays physical #1 (surplus −174 mm in the 2015–2024 window, PM2.5 6.5); Kinamba stays Kruse #1 and got stronger (cleanest on all six pollutants); Sipili stays the cold challenger with its hypoxia penalty now measured.

3d · EZ water, magnetism, earthing, water chemistry — remaining Kruse-adjacent levers

1. Exclusion Zone (fourth-phase) water — Pollack. EZ forms where water meets hydrophilic surfaces under light (IR-driven). Site-level inputs are solar energy and flowing natural water. Measured solar is near-uniform: 5.43–6.17 kWh/m²/day (±7 %), 10.1–11.0 sunshine h/day at all 12 sites — zero discriminating power. Flowing fresh water exists at every highland candidate (Kinamba: Burguret forest streams; Sipili: Ewaso Ng'iro headwaters; Kerugoya: Thuchi/Nyamindi; Ingo Yefwe: eight atlas-named rivers, Lusumu largest); Mufiene's shore had the lake itself. Verdict: EZ is a household lever (spring/flowing source water, light exposure, avoid drinking distilled or demineralized-RO water), not a site-selection lever in Kenya.

2. Magnetism — total field uniform, but the "magnetic pin" geometry does discriminate. Two metrics, two answers. Total field F: 33,558–33,763 nT across all Kenyan candidates (0.6 % spread) — cannot select between them; struck from the composite correctly. Inclination / horizontal share (Kruse's magnetic-pin criterion): this does vary. The project's own analysis (Kruse's Magnetic Pin Criteria Applied to Kenya and Africa, Gerald Shikunyi Kombo, 2026-10-19, ppigrf) found the winners — now independently verified with the offline IGRF-13 model (agreement ≤0.5°):

But the livability filters disqualify both pin winners as residences: Bale/Sanetti sits at 3,000–4,400 m — far above the clinical 2,500 m hypoxia threshold that matters doubly with the family IPF/PH history (§3c measured Sipili's penalty at only 2,567 m); Marsabit is a national park (no residence inside), an arid-zone water island ~530–570 km from Nairobi with 120 km of 4WD murram, medically remote. The pin sites are expedition destinations, not homesteads — the doc supplies the logistics (Lake Paradise campsite, Bale Mountain Lodge with scam-report caveat). Its science verdict matches this project's: field geometry is real; flux-pinning, cloud-dielectric and health-effect claims are not supported — "Earth's field differs by only a few microtesla between places… far below a fridge magnet." Two independent analyses also converged on the same real hazard: rift groundwater fluoride (doc: "use treated water"; §3d item 4: test before drilling). Net: Kinamba remains the best Kruse-compatible place to LIVE — pin geometry equal to Mt Kenya (−19.35°, H 0.944), rift-shoulder basalt geology (partial pin criterion), plus the levers that are evidence-backed: coldest habitable nights, cleanest air on all six pollutants, farm-raised trout DHA (the doc's Kenyan DHA alternative is omena/dagaa from Lake Victoria — which the Mufiene shore also had). Crustal-anomaly point values remain an open gap (WDMAM has no free point-query; the doc did not retrieve Marsabit's either).

3. Earthing/grounding — measured proxy (soil conductivity). Conductivity scales with clay, organic matter, moisture:

All six within 12 clay-% — weak gradient; Nyahururu/Vihiga/Marmanet/Ingo Yefwe/Mufiene soil-blind (SoilGrids down for those cells). Kerugoya's #1 physical rank gains a minor independent confirmation.

4. Water chemistry — fluoride: the one NEW real caveat, and it lands on the Rift-side sites. Geogenic fluoride enrichment in Kenya Rift volcanic aquifers is documented in the peer-reviewed literature: Naivasha catchment study (Science of the Total Environment, 2016), 32-borehole Nakuru County survey (Environmental Earth Sciences, 2018), Kenya Rift shallow-aquifer hydrochemistry (Ecotoxicology & Environmental Safety, 2021) — volcanic formations drive groundwater fluoride far above the WHO 1.5 mg/L limit in rift-floor and rift-shoulder aquifers.

• In the fluoride-risk belt (rift volcanics): Nyahururu, Sipili, Marmanet (Mau escarpment), Kinamba/Burguret corridor (eastern rift shoulder), Naivasha.
• Outside it (non-rift western highlands / lake basin): Kerugoya, Kericho, Kisii, Vihiga, Kapsabet, Ingo Yefwe, Mufiene shore.

Mitigation is cheap and the sites already have it: 1,100–2,000 mm/yr rainfall makes rainwater harvesting the primary drinking source (fluoride-free by definition); any borehole must be fluoride-tested before use. Kinamba survives as Kruse #1 — its trout is farm-raised on controlled water, and 1,117 mm/yr supports full rainwater catchment — but "don't drill before testing" is now a standing instruction for the rift-side shortlist.

5. Negative air ions — proxy only, weak literature. Ion counts rise near moving water, waterfalls and forest: Marmanet (Mau cloud forest), Kinamba (forest margin), Kericho (1,979 mm rain), Ingo Yefwe (~10 km from Kakamega Forest). Health evidence weak; no ranking impact.

6. Schumann resonance / telluric currents. Global ~7.83 Hz fundamental; local variation is not site-selectable and carries no health evidence base. Not scored, not actionable.

3e · Moving from Gataka (the Canopy residence) — measured profile & best alternatives

Exactly where you are: -1.37271746, 36.71575633 — Gataka, Nkaimurunya ward, Kajiado North, Kajiado County; 1,800 m; FAIBA fibre with public IP; ~3–5 km from Kiserian livestock market/slaughterhouse, ~7–8 km from Karen premium buyers, ~25–30 km from Nairobi CBD, Ngong Hills wind farm ~9 km west. Full profile: MASTER-EVERYTHING-GATAKA.md.

Your home, measured (10-yr ERA5 + CAMS 2021–24, same battery as §3c)

Model rank: 43/71, score 0.766 — already above Ingo Yefwe (0.763). Water (0.30 sub-score) is the single big drag; air-NO2 and comfort are the small ones.

Best alternatives if you move (best-for-you model, your own evidence weights)

Near-Nairobi alternatives (≤70 km, same model — 13 metro sites ranked; Gataka is #8)

Full Nairobi-metro list (all 13 model sites ≤70 km, complete axes)

Note on metro water: no site within 70 km of Nairobi has a surplus — Tigoni/Limuru/Thika halve the deficit (449–478 vs 856 mm) but a true surplus still requires the central-highlands move (Kerugoya −202, Nyahururu −467).

Your precise location — the river and the forest (OpenStreetMap, 31 named features)

What this changes: the two nearest named water/green features in the metro are effectively yours — Kandisi at 0.8 km and Oloolua Forest at 1.7 km. The 856 mm deficit is a rainfall fact, but the Mbagathi riparian zone + fractured-volcanic aquifer mean water access at Gataka is better than the deficit number alone suggests, and the forest edge partly offsets the Ngong Rd NO2 plume. Tigoni/Thika still win on rainfall and traffic air — but your plot has the best green-water interface in the metro.

The residence that actually beats Gataka — Limuru ridge, measured head-to-head

Verdict: Limuru ridge is the residence that beats this plot — it wins the two axes Gataka loses (water 4.4×, traffic air by location), keeps and improves the elite cold nights (5.0 °C), adds +64 % soil carbon, upgrades the forest class from dry to wet Afromontane, and sits upstream of your own river. It costs you 457 m of altitude (no hypoxia at 783.5 hPa), 2.6 °C of warmth, and ~55 min on the goat run.

Deeper-forest variant: Kijabe/Gatamaiyu forest edge (-1.01, 36.66, ~2,380 m) — coldest nights of all 16 sites (coldest-5 % = 7.3 °C, wet-bulb 14.8), but soil data blind and altitude creeps toward the 2,500 m ceiling. Choose Limuru ridge proper for the residence.

Tigoni remains the top model score (0.833) and is ~10 km closer to Kiserian — the pick if the goat business must stay weekly; Limuru ridge is the pick if water and forest class matter more.

Scenario verdicts

• If you must stay near Nairobi → Limuru ridge (the measured Gataka-beater: 4.4× better water, colder nights, +64 % soil carbon, upstream of your own river — see head-to-head above) or Tigoni (top metro model score 0.833, ~10 km closer to Kiserian). Thika if water/air/comfort + town services beat market proximity; Kiserian (4 km) fixes air only.
• Farming/water-first move → Kerugoya. Biggest single-axis upgrade available: a genuine 20-yr surplus where Gataka has an 856 mm deficit.
• Maximum Kruse-lever move → Kinamba (or Naro Moru for town + highway). Preserves your elite cold nights, doubles air cleanliness to WHO AQG, adds trout DHA. Standing caveat: harvest rainwater, fluoride-test before drilling.
• Thermal-comfort move → Embu. Only top-8 site inside the 20–25 °C mortality optimum.
• Stay and fix (highest-return option if the goat business + fibre income stay central): Gataka's weaknesses are purchasable — roof rainwater catchment (942 mm × roof area) or a tested borehole closes the water gap; 50 m+ setback from Ngong Road plus a dense vegetation screen cuts the NO2/SO2 traffic plume. You keep MinT 6.4 °C, measured good soil, UV 9.4 and a 0.766 score without leaving a 3–5 km supply chain and a 7 km premium market.
• Coast home (Kigongoni/Matuga) is not a move target: 365/365 tropical nights, wet-bulb 26.3 °C (highest of all 14 sites), sandy low-fertility soil, +189–529 mm deficit. Measured virtues: cleanest CO in the entire set (135 µg/m³ — sea breeze) and PM2.5 7.7. Keep it as the income/visit asset, not the residence.
• Elsewhere great (outside Kenya, from the Magnetic Pin doc): Bale/Sanetti tops Africa on pin geometry but is disqualified as residence by 3,000–4,400 m altitude + family IPF/PH history. Marsabit tops Kenya on pin geometry but is a park/arid/remote. Visit both; live nowhere above 2,500 m.

4 · What to buy — purchases and where to look

Everything Olutsotso-specific that exists for free is already in C:\Users\HP\Downloads\Olutsootso (5 Dalgish papers, all official PDFs verified). This is the complete gap list:

Action order: file the ILL request for #1 first (free, 1–3 weeks typical turnaround) → then free map-archive browsing (#3) for Mufiene → only then spend on #2 if Wagner Vol. II matters for land tenure.

5 · Camps & lodges — the visit list (verified 2026-10-21)

Booking rails: KWS accommodation via reservations.kws.go.ke, park entry via kwspay.ecitizen.go.ke (official). Non-resident fees conflict across KWS pages (Marsabit shows $22 and $40) — confirm on eCitizen before travel.

5a · Magnetic-pin sites (expeditions)

Mt Marsabit — Kenya pin #1 (I −13.1°, H 0.974, IGRF-13 verified):

Access: 530–570 km from Nairobi; ~120 km murram — 4WD in the dry season. Town hotels flagged for poor hygiene/unsafe wiring (Ebisa, Jirime, Victorian) — avoid.

Bale Mountains / Sanetti — Africa pin #1 (I −1.2°, H 1.000, verified):

Hazards: 3,000–4,400 m altitude (clinical threshold 2,500 m — acclimatize; family IPF/PH history makes Sanetti a visit, never a stay), guides/scouts required on the plateau, check Oromia security advice, ~400 km from Addis.

Chyulu Hills — Kenya pin #2 (I −25.0°, H 0.906, verified): Campi ya Kanzi — Maasai-owned Kuku Group Ranch between Amboseli and Tsavo West; carbon-negative, 100 % solar since 1996, cloud-forest hikes, Kilimanjaro views; the flagship stay for this pin. Plus KWS public campsites in the park (check kwspay.ecitizen.go.ke).

Mt Kenya — pin #4 (I −19.3°, H 0.944, verified; coldest camps in Kenya): circuit camps Met Station (3,050 m, ranger post, water) · Old Moses (3,300 m, hut dorms + camping, first night on Sirimon) · Mackinders Camp (4,200–4,300 m, Teleki Valley, Sirimon–Naro Moru route) · Shipton's (north side) · Austrian Hut / Point Lenana (summit band). All KWS — reservations.kws.go.ke; fees on a 24-hour conservation cycle, resident vs non-resident.

5b · Kruse-lever getaways within the liveable zone

• Kinamba / Nanyuki belt (Kruse #1 site): Trout Lodge and the Burguret fly-fishing water (DHA lever at the source); Il Ngwesi Eco-Lodge — Laikipiak Maasai community-owned, UNDP Equator Initiative Award 2002, Ecotourism Kenya bronze, neighbours Lewa/Borana/Lekurruki; profits fund community schools, cattle dips, water.
• Aberdare cold belt (Limuru/Kinangop/Aberdares cold-exposure note): The Ark, Treetops, Sable Lodge, plus KWS bandas, self-catering cottages and high-altitude campsites (aberdarepark.org).
• Nyahururu/Kinangop plateau: coldest drivable highlands from Nairobi (Sipili's 4.7 °C MinT country) — day-trip cold exposure without the 2,500 m penalty.

5c · Ancestral circuit (roots + the Mufiene question)

• Kakamega Forest (~10 km from Ingo Yefwe): Rondo Retreat Centre (south side, supports forest conservation), Udo's Bandas & Campsite (KWS, self-catering, budget, forest heart), Buyangu Hill viewpoint (KWS gate fees). Kenya's last rainforest remnant — the negative-ion/forest axis made walkable.
• The pilgrimage: Bukura Market → Khusokomi ridge (GPS-verified 225 m from the homestead, 8 m higher) → Ingo Yefwe. Combine with elder interviews: Mufiene's location, the Vamwende ↔ Abamweche/Mwende rain-magic hypothesis, Tier 3a word meanings.
• Lake Victoria / Kavirondo Gulf (Mufiene search): base Kisumu or Homa Bay; omena/dagaa landings for the DHA-from-the-lake angle; ask Luo/Luhya elders on the gulf shore about a vanished Tsotso place-name.

6 · Precise playbook — move, visit, buy, elders

Fees: [V] = official KWS Conservation Fee card Oct 2025 (scripts\kws-fees-2025.pdf, fetched 2026-10-31 from kws.go.ke) · [P] = reasoned/typical, confirm before travel · [U] = unverified. Coordinates: OpenStreetMap lookups 2026-10-31 (scripts\trip-coordinates.json).

6a · Official KWS entry fees (per adult/day, EAC citizen KSh — non-resident USD) [V]

6b · MOVE — precise target: Limuru–Kijabe ridge

Target zone: the B3 Limuru–Kijabe road corridor between Limuru town (-1.1108, 36.6431) and Kijabe; measured ridge point -1.1022, 36.6475 (deficit +122 mm, MinT 5.0, SOC 3.76 %). Three scouting corridors:

Scouting day (from Gataka, ~45 km, ~1 h): matatu ~KSh 250–400 total [P] or drive (~KSh 1,000–1,500 fuel). Do, in order: Kiambu county planning office zonation → registered surveyor beacon check → ArdhiSasa/green-card title search → FAIBA/Safaricom fibre at the exact plot → borehole survey quote → Gatamaiyu/Kijabe forest-edge walk.

6b-2 · Buying in ACRES — where is best

One-buy verdicts: best value acres = Burguret (a 5-acre forest-edge parcel for the price of a Limuru 50×100). Best farming acres = Kerugoya eastern belt. Best acres within reach of Nairobi and the goat business = Kijabe/Lari. Buying at all three beats any single large purchase: Burguret for the Kruse levers + land bank, Kerugoya for food/water, Kijabe for the residence — total ≈ KSh 4–8 M for ~7 acres across the three best zones.

6c · VISIT — the Mufiene elders trip (base Kisumu)

Get there: Madaraka Express Nairobi→Kisumu ~KSh 1,000 economy / ~1,500 business, ~5 h [P — metrail.co.ke unreachable today]; bus KSh 1,800–2,500 [P]. Local: Kisumu→Homa Bay ~KSh 500–800 [P]; Kisumu→Kakamega ~KSh 700–1,200 [P]. 5–7 day budget ≈ KSh 15,000–30,000 staying family at Ingo Yefwe (free).

The ask script for elders (all sites): "Is there a name like Mufiene (Mu-jiene, Mu-fye-ne) for an old lakeside place? Which clan left the gulf for Kakamega around 1800–1850? Do you know Anyika?" Record audio (consent first), note exact pronunciation, cross-match OLUTSOOTSO-LEXICON.md Tier 1/3a.

6d · WHAT TO DO — every other place in one line

6e · BLIND soils — status

SoilGrids (rest.isric.org) returned 503 all day 2026-10-31 — Nairobi CBD, Ngong town, Ongata Rongai, Machakos (+16 sites) remain soil-blind; scripts\fill-gaps.ps1 is re-runnable the moment the service recovers. Impact on rankings: negligible — blind metro sites share Gataka's red-volcanic belt (measured SOC 2.29 %, CEC 24.0), soil carries 10 % weight, and their 812–955 mm deficits cannot be out-scored by soil. Tigoni/Limuru (SOC 3.75–3.76 %) keep the win either way.
