Nishi reusable house-by-house soil analysis with deficiency-gated recommendations vs university extension labs and mail-in consumer kits and soil-health labs and in-field sensor platforms -- Aug-2026 field

Overview

The purpose, declared position and evidence coverage of this domain. Source presence and completed acceptance are different measures.

Where we are. MEASURED 2026-08-19: no Nishi soil instrument exists. In tree and measured: the lab-science service facade (lab_dispatch -- grounded chemistry and physics verbs on the shared service base), the GTM channel facade, the product decomposer. The field is mirrored end to end: 15-dollar three-day extension Mehlich-3, mail-in kits, Haney and CASH soil-health panels, and farm-scale reusable spectroscopy handhelds.

Where we need to go. OPERATOR ASK (2026-08-19): soil-science analysis better than the ag colleges, reusable if possible, easy to go house by house, and feedback that allows the upsell. The thesis: do not out-lab the labs -- out-TRUST the incumbents. Reusable instrument at the door, calibration against extension-lab splits (the ag college becomes our referee, not our rival), plain-language honest reports, and a recommendation engine that mechanically refuses unearned upsells.

The unit. 1 u = one measured session-leg (organ plus gate plus live flip), the standing calibration.

Cost to the analysis and report engine: 4 u. SS1 panel definition, SS3 prescription tables, SS4 report emitter, SS5 upsell refusal gate -- all organ work on the labsci base.

Cost to a calibrated field instrument decision: 2 u more plus instrument. SS2 runs the probe buy-vs-build: evaluate a bought handheld against extension splits before any thought of building sensor hardware. 6 u cumulative.

Cost to a route-ready service pilot: 3 u more. SS6 household route plane with consent rows, SS7 pilot gate over a declared street of houses with paired lab splits. 9 u cumulative.

Research bar. MU extension Mehlich-3 package, the price-performance bar is measured on the 2026 extension lab benchmark for a complete fertility panel. Theirs: 15 dollars a sample, about three days [mumehlich]. Ours: our per-house reading must land within the calibration bounds of that panel on paired splits, at the door in minutes -- and the service prices the FEEDBACK, not the chemistry.

Business case

Axis	Position	Figures	Decision
Investment	Organ legs ride the labsci base; the instrument decision is a BUY evaluation first -- farm handhelds exist today [handhelds] and extension splits cost 15 dollars each as ground truth [mumehlich]	estimated 9 u to a route-ready pilot; instrument capital gated on the SS2 accept rule	fund the engine legs now; buy one handheld for evaluation; never build sensor hardware before BUY fails a pre-declared bound
Market	Every house with a lawn is a candidate; the incumbent door-to-door model proves the demand shape at national scale [trugreen]; extension pricing anchors willingness to pay for chemistry [mumehlich] [unhprices] while kits anchor the consumer ceiling [mysoil]	the service prices the standing FEEDBACK relationship, not the assay	sell the season relationship: reading plus report plus only-what-you-need plan, re-measured each visit
Opportunity cost	The labsci facade gains a second grounded domain either way; SS4 and SS5 (honest report, refusal-gated selling) are reusable across every door-to-door service the estate ever runs	the trust machinery is the durable asset even if soil is not the wedge	charge SS4 and SS5 to the service-substrate program
Go to market	House-by-house with the instant reading IS the demo -- the incumbent leads with a sales analysis [trugreen], we lead with a measurement; soil-health literacy is rising on the Haney and CASH vocabulary [haneycmp] [cornellcash]	the honest report is the referral engine	start one street pilot (SS7), publish the calibration record, let the paired-split honesty be the pitch
Buy vs build	Chemistry: BUY (extension labs at 15 dollars are unbeatable reference chemistry [mumehlich]). Instrument: BUY first from the handheld class [handhelds], BUILD only on a failed pre-declared bound. Trust engine: BUILD -- the refusal gate does not exist to buy	the wedge is the trust engine, not the sensor	compose the labs, evaluate the sensors, build the honesty

Evidence profile — what the gaps on this board actually are

Measured by nx_swcompare_evidence, read back by nx_evprofile_lib. Every figure is a count with its denominator — there is deliberately no score, no grade and no percentage anywhere in this band, because a stored scalar is a field a seat can edit and a counted partition is not.

proven able to fail counts the gates that have a RECORDED RED — nx_gate_bite mutated the gate subject, rebuilt it, watched the gate go red, and that record is inside the shared TTL. never bitten is its complement over the same denominator: those gates ran and were green, and nothing has ever shown them able to detect anything, so their green is a statement about this run and not about the gate. green at 0/0 is a separate and much weaker observation — the gate printed GREEN on a zero denominator, so its own tooth counter says it examined nothing. A gate can be green, non-zero, and still never bitten; that is the common case and it is now visible instead of implied.

partition: grounded + unsupported = 6 vs present 6 · named + unnamed + withheld = 8 vs open 8 · both reconcile

liar-kill conj=GPqN · first failing conjunct: quorum

graded document: BUILDROOT tree, 6637 bytes · gates map: NONE · stamped 36d 23h ago · STALE against the shared TTL of 604800s — this is evidence about a build nobody can vouch for now · source ../knowledge/status/evstamp_soilscience.verdict

Gap class	What it is, and the work it names
CLAIM-ONLY	No declared gate ran for this board, so every capability mark here rests on a symbol existing in source and on nothing executing. The remedy is to WRITE a `.gates` map naming gates that already run — authoring, not research.
STALE	This profile is older than the shared TTL, or its clock ran backwards. It is reported as unusable rather than as fresh, because being wrong in the direction of refusing is the safe direction.

This band reports the referee counts. The per-axis worklist rows — which axis is unsupported, which watch is ready to flip, which gap is unnamed — are printed by nx_swcompare_evidence soilscience itself and are not carried on the stamp, so this page names the classes and the producer names the rows. That split is stated rather than hidden: a count without a worklist is not actionable, and this band is honest about which half of that it is.

Production map

Follow the dependencies, declared acceptance criteria and recorded priorities. Inspect source binding before treating a rank as executable work.

Ranking source binding: PLAN_MATRIX_BOUND_ONLY. Recorded priorities require current acceptance evidence and resource checks before execution.

Ranking matches the captured plan and matrix only. Latest execution outcome, research freshness, accepted delivery and investment return are unverified.

Recorded priority estimates

Order from nx_compare_rank (nx_dr_ocm: (deficit + cost-of-delay + option + enables) x sponsor x self-sufficiency x momentum / cost). FINISH rows are rungs whose symbol is present but whose organ is short of full adoption: listed before new work by this heuristic. Priority is not measured delivery cost or execution readiness.

Ladder verdict. NOT DECLARED. This board names no dated best-in-class or frontier target and no rung roles (sotatarget and rungrole rows on its plan); the ranker labels it NO-LADDER until it does, and until then its rungs climb toward a target nobody has written down. Bars read NO-BAR against the current month 2026-10.

Rung dossiers — every record that bears on a rung, in one place

Joined by symbol, never typed. Each dossier is assembled on every publish from the rows this board already carries: the plan's rung row, the matrix row that carries its contract symbol (its status re-measured by the one symbol ruler), the gate the organ declares and the verdict the evidence referee recorded on its last run, the reference marks in the rung text, the design rows that name the rung and the work log filed against it. The capability matrix links each cell to its dossier and each dossier links back to its cell and forward to the rungs it stands on; a dependency naming no rung on this plan is written as UNRESOLVED rather than linked. Absences are named: NO-MATRIX-ROW, NO-GATE-DECLARED, UNRECORDED.

Gate verdicts: UNSTAMPED — no per-gate verdict artifact is published for this domain yet (nx_swcompare_evidence soilscience writes it beside its stamp); every gate below reads UNRECORDED until it runs.

Gate declarations: knowledge/organ_gate.conf read from this working directory (1 rows) and from the estate root (196 rows); rows in both counted once: 0; declarations read: 197. Every declaration in either copy counts, so a stub beside the publisher can never hide the root.

Capability comparisons

Compare the field, search individual capabilities and open their source and adoption evidence. Documented presence does not establish comparative quality.

Position map — centrality and distinctiveness

The four-quadrant map the field uses for brand strategy (Dawar and Bagga, HBR June 2015), re-derived from this matrix on every publish. Centrality is the share of the category's feature mass a player covers, each feature weighted by how many hold it; distinctiveness is the average lead over each rival on the rows the player holds; breadth is the depth-weighted share of the whole matrix (the bubble); depth is how deeply the rows held are held; momentum is the day-over-day move off the spine (green rising, red falling, grey until day two); the dashed path runs first day → previous day → today. Dividers are the category means. Axes are fitted to the field of play, so read the tick numerals, not the frame. Rival marks are documented presence, so a rival's position reads the record, never its quality. The picture grades its own readability below; the table beside it is the same data for a screen reader or a second method.

Rows. 14 feature rows mapped of 14 matrix rows; 0 substrate rows (kernels, bounds and instruments the plan's rungrole marks substrate) are the estate's scaffolding, not category features, and stay off the map

Views. 2D cut: centrality, distinctiveness · 3D cube: centrality, distinctiveness, breadth · axes registered: centrality, distinctiveness, breadth, depth, momentum · a board picks its own in knowledge/compare/soilscience.cdmap (cut|x|y, cube|x|y|z); absent = the HBR defaults

bubble area = breadth · ring = momentum (green rising, red falling, grey until day two) · dashed = category means · axes fitted to the field of play: centrality 100–800, distinctiveness 100–800 of 0–1000 permil (the full range put every player in one corner)
readability of the 2D cut, self-graded by the layout ruler: label overlaps 0 · labels over marks 0 · off-canvas 0 · unresolved labels 0 · mark overlaps 1 (a fact of the data: two players that close are that close) · data spread 682 permil of the plot · quadrant words unseated 0
text contrast, measured with wcag2-ratio (floors from contrast.conf), light theme: labels 16.24 (floor 4.50) · notes 16.24 (floor 4.50) · quadrant words 5.89 (floor 4.50) · tick numerals 5.89 (floor 4.50) · axis titles 5.59 (floor 4.50) · dark theme: labels 13.78 (floor 4.50) · quadrant words 5.55 (floor 4.50) · axis titles 5.97 (floor 4.50) · dark classes under their floor 0 (one figure serves both themes: a dark shortfall is a token to fix, never a class to hide) · classes refused under their floor 0 (a refused class is not drawn; the scale classes are measured, never hidden) · export: SVG PNG (receipt, rendered by the estate's own rasteriser from this page)

axes fitted: centrality 100–800 · distinctiveness 100–800 · breadth 100–350 permil · farther bubbles are painted first, nearer ones over them · the floor shadow is each bubble's (x, y) at height 0

How to read this evidence. A Nishi source mark records whether the named symbol is declared in the selected source file. It does not establish working behavior or accepted delivery. A watching tag names an expected source entry; discovering it updates source coverage only. A dark tag means the file exists but the named symbol was not found: inspect the source and contract before assuming the capability is missing or renaming code. Peer codes are authored assessments; unassessed means no comparison is established, not absence. Qualification, deployment identity, runtime observations and acceptance must carry their own evidence. Adoption records the catalog's observed path through source, build, promotion, registration and invocation; libraries use importer evidence and gates use declared execution surfaces. A full catalog path does not establish quality, freshness or a successful user outcome. Partial and unknown states retain their stated next action. Census stamps: importers asof 1790637268, gate census asof 1790104131 (unix seconds; -1 = census absent).

Rival-claim provenance. Every Yes, Best or Part mark in a rival column is a claim about someone else's product. A cited row carries a reference mark that resolves to a pinned mirror (the refs gate measures that); an uncited row is an observation read and is badged in its evidence until a reference lands. The badge is the receipt, never the proof: a mark proves a mirror exists, not that the mirror supports the code. The rows are counted below.

Rival claims, counted

Inspect risks, technical debt, rendered observations, experiments and references. Read scope and limitations alongside every result.

Risk register

Risk	Likelihood x impact	Mitigation
The handheld reads badly on residential soils and the pilot publishes wrong numbers	probable x high	SS2 accept rule pre-declared; every report carries bounds; paired splits every Nth house keep the referee in the loop; a failed bound stops the lane at M1, not after a season of bad calls
A watch contract flips on symbol existence, so a stub reads green	possible x high	the flip is the receipt, the rung gate is the proof
The honest-refusal model sells less per visit than the incumbent upsell machine	probable x medium	that is the bet, stated plainly: retention and referral against per-visit extraction [trugreen]; the pilot gate banks per-house revenue so the answer is measured, not argued

On these two registers. Rows are declared in the domain's plan file and carry the debt id, which is the join key back to the sovereign debt plane — that plane, not this page, is the authority on state. Reconciling them automatically (the regen reading the plane and refreshing these rows) is a named, owed rung; until it lands, treat an id here as a pointer to look up, not a status to trust.

Honest verdict. The bar to beat is not the ag college -- it is the ag college PRICE: Missouri extension now runs a Mehlich-3 complete panel (P, K, Ca, Mg, S and micros) at 15 dollars a sample with results back in about three days [mumehlich], and the extension pricing ladder is published [unhprices]. Consumer mail-in kits read pH plus 13 plant-available nutrients about a week out [mysoil]. Soil-HEALTH labs add the biology: microbial respiration and water-extractable organic carbon on the Haney panel [haneycmp], and the Cornell CASH framework scores twelve biological, physical and chemical attributes [cornellcash]. The reusable in-field class already exists at farm scale -- Stenon FarmLab reads N, P, K, Mg, SOC, pH, texture and moisture in seconds by combined optical and impedance spectroscopy [stenon] -- but the handheld class is subscription-priced for agriculture and carries cloud-calibration debt [handhelds]. And the incumbent door-to-door residential model is a sales machine: a lawn analysis at signup and a documented aggressive-upsell reputation [trugreen]. The Nishi wedge inverts it: a REUSABLE instrument at the door, minutes-per-house readings calibrated against extension-lab splits, a plain-language honest report -- and an upsell engine that mechanically REFUSES to recommend anything the measured soil does not need. Trust is the moat; the refusal gate is the proof.

Person · product · place — not yet measured for this domain

Every compare carries this layer. Declare knowledge/compare/soilscience.ppp (rows surface|nishi or c1..c4|label|url|connect naming OUR live surface and each rival's front door), run nx_ppp_probe domain soilscience, and this section fills itself on the next beat: the same ruler on both sides — privacy and CX (third-party hosts, tracker classes, cookies, security headers), design and longevity (design hygiene, computed WCAG contrast, render-blocking resources, unsized media, script weight, theme and motion queries), findability (landmarks, skip link, on-site search, breadcrumb, headings, internal links).

The field — discovered, not chosen

Rows written by nx_field_discover from soilscience.seeds: the industry's own lists (Wikipedia wikitext, GitHub topics, awesome lists) read mechanically, every candidate counted across seeds. The matrix columns above are a SEAT'S pick; this band is the population they were picked from, and the stats line measures one against the other. A rival here is a lead, never a verdict — it earns a column when its capabilities are read and pinned.

Discovery receipt. One row per counter the run wrote, in the receipt's own order; the rival rows follow in their own table.

Exclusive and shared capabilities

One capability is graded on one board; every other board references it. The fleet duplicate census (nx_rivalcensus dupes, on the fleetdupes clock row) reads every board's matrix and names each capability graded as a row on two or more boards, with a home derived from evidence: rung when exactly one board's plan contracts the symbol (that board is starred), gates when no plan contracts it and exactly one board's executed gate map runs the organ's gate (that board is plussed), ambiguous when several boards carry the deciding evidence (a decision for their seats), and none when no evidence decides it, with the reason beside it: unmapped (no board of the duplicate declares a gates map; declare the maps) or unproven (a map exists and runs none of the organ's gates; gate the organ on its proving board, or declare it a shared library by policy). A home elsewhere means this board should carry an @xrow reference to the home board's row rather than a graded row of its own; a home here means the other boards should. The table is this board's slice of one estate-wide census: the shape is shared, the rows are the board's.

This board grades 14 capabilities: 11 exclusive to it and 3 shared with other boards. Shared rows on this page: 3 = home here 0 + home elsewhere 1 + ambiguous 0 + undecided 2 + refused 0 (partition 3); undecided = unmapped 0 + unproven 2 + unevidenced 0; homonyms 0; since the previous census: new 0, resolved 0. Census FRESH age_s=6693.

Gaps from the record — what the estate does that no board carries

The record census (nx_goalmap record) reads the invoked-tool population and every plan queue row and files each organ or directive that NO matrix, plan or gates row names. A row here is a callout the boards missed: adjudicate it onto a board or declare it infrastructure. Census state STALE (age 1395798 s), sources read 4 of 7 declared — a BLIND census is a FLOOR: unread sources can only add rows.
