Food Science and Engineering Suite

Compare capabilities and delivery evidence. Source discovery, qualification, deployment and accepted outcomes are separate; an open contract names work still to verify.

The roadmap-binding board behind /compare/foodscience. Rival codes copied verbatim from foodscience.sota; Nishi cells are MEASURED -- the ranker requires the implementing symbol as a top-level func in the real organ source on disk.

Overview

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

Where we are. Measured 2026-08-21 from foodscience.sota and the organ sources on disk. STRONG and gate-proven: 14 disciplines composed in one integer-exact suite where each incumbent is deep in one or two, with structural refusals rather than warning strings -- a low-acid food may never be water-bath canned (pv_canning_admit), the Leistner combined hurdle is proven to BEAT either single factor (pv_hurdle_beats_single), Atwater energy and FDA percent-DV are computed from first principles rather than read off a label, and nx_food_ground_gate runs 8/8 GREEN against a durable local store with no network in the path while refusing inadmissible source licences fail-closed. WEAK, and the page already says so in six rows: THE SUITE HOLDS NO MEASURED DATUM ANYWHERE. That single absence wears two masks -- no measured microbial growth or death curve on the safety half, and no measured food-composition record on the nutrition half, where nx_nutrition carries sixteen foods as hand-entered constants. Beyond it: the conduction solver is two-dimensional where the field is three, no organ owns unit operations at all, no instrument export is ever read, and the citation machinery that already grounds 7 of 7 science RULES does not reach the CONSTANTS. THE HONEST BOUNDARY, stated here rather than smuggled into a rung: commercial support and an SLA are not an engineering rung and never will be, and a GUI is owned by the surface lanes, not by this suite -- neither appears in foodscience.matrix. THE STATISTICS AND SENSORY HALF IS ALSO ABSENT FROM THIS LADDER ON PURPOSE: SPC depth against Minitab and sensory depth against Compusense are real Part grades on the sota page, but a matrix carries ONE @cols line and those rungs need Minitab and Compusense as rivals while these need ComBase and COMSOL. Naming them here against the wrong rival field would be the measured-a-different-subject defect; they are stated as owed rather than mis-scored.

Where we need to go. Move this suite from A MODEL NOBODY HAS CHECKED AGAINST REALITY to one whose predictions are compared with measured data and whose constants each name their source. Concretely: measured composition records feed the same NxFood the hand catalog uses, predicted lethality is compared against measured curve points with the signed error printed, conduction is solved in three dimensions with the two-dimensional incumbent as its degenerate-case oracle, unit operations get an organ instead of nothing, an instrument export parses into the inputs the rheology organ already takes, and every named constant maps to a cited mirrored source with the uncited ones listed. The exceed this suite holds is that its gates assert EXACT integer equalities; every rung below must stay expressible that way or it has broken the property that makes the rest checkable.

The unit. 1 u = one measured session-leg (organ plus gate plus the live flip). Local calibration: the water lane next door built three organs and 44 teeth in one working day on 2026-08-14 on this same substrate, so a rung extending an existing organ with a new function and its teeth is 1 u, a rung that must also parse an external record is 1.5 u, and a rung that adds a solver dimension or a new organ is 2 u.

Where we are: 6 open rungs. Three landed and gate-proven, six open. Every open rung is a row foodscience.sota already publishes as an absence or a partial. Counts measured at emit below this line.

Cost to a suite that answers to measured data: 3 u. FS1 the composition ingest and FS2 the curve validation. These two are the whole of the honest answer to the largest gap this page declares about itself.

Cost to physics depth: 7 u. Adds FS3 the third conduction dimension and FS4 the unit-operations organ.

Cost to instruments and provenance: 9 u. Adds FS5 the instrument export parser and FS6 the constant-to-source coverage map.

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 = 3 vs present 3 · named + unnamed + withheld = 6 vs open 6 · both reconcile

liar-kill conj=GpqN · first failing conjunct: present

graded document: BUILDROOT tree, 5541 bytes · gates map: NONE · stamped 37d 5h ago · STALE against the shared TTL of 604800s — this is evidence about a build nobody can vouch for now · source ../knowledge/status/evstamp_foodscience.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 foodscience 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.

Declared roadmap — contract, acceptance, executor, effort

Rung	Closes with	Definition of done (pre-declared)	Executor	Est.
12-D botulinum cook with a structural refusal (FS0A)	pv_canning_admit	LANDED. D-value z-value and the 12-D cook computed exactly, and the load-bearing part is not the arithmetic but the REFUSAL: a low-acid food routed to a water bath is refused by construction rather than warned about [combase]. Listed so dependents carry its momentum	Organ	0 u
Leistner combined-hurdle stability (FS0B)	pv_hurdle_beats_single	LANDED. The hurdle model implemented exact [leistner2000], with the discriminating tooth being that a combined pH and aw hurdle is proven to beat EITHER single factor -- an implementation that merely returned stable for both would pass a suite that only checked the combined case	Organ	0 u
Atwater energy and daily value from first principles (FS0C)	nt_kcal_per_100g	LANDED. Energy computed from macronutrients rather than read from a label, scaled to portions and whole meals with FDA percent-DV coverage [fooddata-central]. Listed so dependents carry its momentum	Organ	0 u
Measured food-composition record ingest (FS1) after FS0C	nt_fdc_ingest	nx_nutrition holds sixteen foods as hand-entered constants, which is precisely why the sota grades the measured empirical database ABSENT and FoodData Central Best [fooddata-central]. ACCEPT RULE PRE-DECLARED: a mirrored FoodData Central record parses into the SAME NxFood struct the hand catalog uses and is scored by the EXISTING nt_kcal_per_100g -- one ruler, never a second energy computation for ingested foods. THE LOAD-BEARING TOOTH IS AN EQUALITY, not a tolerance: for a food that exists in BOTH the hand catalog and the ingested set, the Atwater energy computed from the ingested macros must equal the energy the organ already computes for its hand-entered twin EXACTLY, because a suite whose exceed is integer determinism may not accept a band here. A record missing a macronutrient yields UNKNOWN and never zero, since zero fat is a claim and a missing field is not. The partition must print and sum: records read equals ingested plus refused plus unparseable. This rung closes the sota's Micronutrient content Part grade in the same pass and the row note says so	Organ	1.5 u
Predicted lethality validated against measured curve points (FS2) after FS0A	pv_curve_validate	We gate the hazard envelope structurally and hold no measured curve, which is the entire reason ComBase is Best on two rows of this page [combase]. ACCEPT RULE PRE-DECLARED: at declared pH, water-activity and temperature points taken from a mirrored and content-pinned measured source, the model's predicted log reduction is compared with the measured value and the SIGNED error is printed per point -- signed, never absolute, so a model that is systematically optimistic shows as a bias instead of averaging to nothing. A point outside the model's declared validity envelope reports OUT-OF-ENVELOPE as its own third state and does NOT score as agreement, because an axis that cannot see must abstain rather than acquit. ANTI-VACUITY TOOTH REQUIRED: a deliberately wrong z-value must push at least one point outside the declared band, or the comparison has not been shown capable of disagreeing	Organ	1.5 u
Transient conduction in the third dimension (FS3)	hc3d_run	hc2d_run is a real explicit finite-difference transient solver and it is two-dimensional, which is why the sota grades 2-D transient Part and 3-D CFD absent against COMSOL Best [comsol]. EXTENDS THE INCUMBENT ORGAN -- a second conduction solver is refused by construction. ACCEPT RULE PRE-DECLARED, and its two teeth must BOTH hold because either alone is passable by a wrong implementation: with the third dimension one cell thick the new solver reproduces hc2d_run's centre temperature EXACTLY at every step (the degenerate-case oracle, an equality not a band), AND for a genuinely three-dimensional geometry -- a cube against an infinite prism of the same cross-section -- the centre must reach the surface temperature SOONER, because a cube loses heat through six faces and a prism through four. A solver that simply returned the 2-D answer would pass the first tooth and fail the second, which is what makes the pair a discrimination test rather than two spot checks	Organ	2 u
Unit-operation mass and energy balance (FS4)	uo_balance_solve	The suite conserves mass and stops there, against Aspen Plus rigorous unit-op models at Best [aspen-plus]. NEW ORGAN DECLARED IN THE ROW rather than bolted onto a thermal organ, because no organ in the suite owns unit operations and single responsibility is cheaper to keep than to restore. ACCEPT RULE PRE-DECLARED: for a declared unit operation both balances close EXACTLY in integer units -- mass in equals mass out plus accumulation, energy in equals energy out plus accumulation -- and a stream whose composition is under-specified REFUSES with the missing quantity named rather than closing the balance by inventing the remainder, which is the one failure mode that makes a balance solver worse than no balance solver. NEG-CONTROL: a deliberately unbalanced fixture must be refused and must name which balance failed	Organ	2 u
Instrument export parsed into the rheology inputs (FS5)	rh_instrument_ingest	Texture Profile Analysis and Herschel-Bulkley yield are computed from values typed by hand; the sota grades lab instrument integration ABSENT. ACCEPT RULE PRE-DECLARED: a banked instrument export parses into the inputs nx_rheology already takes and reproduces the organ's EXISTING hand-entered fixture EXACTLY -- the parser is proven by agreeing with a known answer, not by producing a plausible one. A malformed export is refused NAMING the field that failed, never partially accepted. SCOPE DECLARED: this rung reads a file an instrument wrote and drives no hardware, so it closes the data half of that row and leaves acquisition open, and the row note says so rather than letting the flip imply more	Organ	1 u
Every named constant maps to a cited source (FS6)	fd_constant_cite_map	fd_sci_cited and fd_sci_cite_of already ground 7 of 7 science RULES; the CONSTANTS -- the botulinum D-value, the z-value, the water-activity thresholds, the Atwater factors, the daily values -- are not covered, and the sota grades published validation ABSENT. ACCEPT RULE PRE-DECLARED: every named constant in the suite's organs maps to a cited mirrored source or is listed UNCITED by name and file, the partition of constants prints and sums, and the uncited count is a SHRINK-ONLY ratchet that self-seeds on first sight -- never a fresh absolute bar, because a detector that is red on the day it ships is one everyone learns to ignore. THE DIRECTION NOBODY AUDITS IS THE ONE THIS RUNG MUST GET RIGHT: an omitted constant flatters the number, so the enumeration is of the SOURCE and the coverage is computed against it, never the other way round. This rung claims coverage and never claims certification	Organ	1 u

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.

Bar freshness, counted
Class	Count	Note

Treatment verdict. NOT DECLARED. No rung on this board declares its three-step treatment (a treat row naming the MCP row, the API route, the primitive it composes, the workflow that composes it and the agent beat that runs it); the ranker labels every rung TREATMENT-UNDECLARED until it does.

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 foodscience 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.

ACCEPT RULE PRE-DECLARED: at declared pH, water-activity and temperature points taken from a mirrored and content-pinned measured source, the model's predicted log reduction is compared with the measured value and the SIGNED error is printed per point -- signed, never absolute, so a model that is systematically optimistic shows as a bias instead of averaging to nothing. A point outside the model's declared validity envelope reports OUT-OF-ENVELOPE as its own third state and does NOT score as agreement, because an axis that cannot see must abstain rather than acquit. ANTI-VACUITY TOOTH REQUIRED: a deliberately wrong z-value must push at least one point outside the declared band, or the comparison has not been shown capable of disagreeing

Contract	`hc3d_run` · executor Organ · 2 u · stands on nothing
Definition of done	hc2d_run is a real explicit finite-difference transient solver and it is two-dimensional, which is why the sota grades 2-D transient Part and 3-D CFD absent against COMSOL Best [comsol]. EXTENDS THE INCUMBENT ORGAN -- a second conduction solver is refused by construction. ACCEPT RULE PRE-DECLARED, and its two teeth must BOTH hold because either alone is passable by a wrong implementation: with the third dimension one cell thick the new solver reproduces hc2d_run's centre temperature EXACTLY at every step (the degenerate-case oracle, an equality not a band), AND for a genuinely three-dimensional geometry -- a cube against an infinite prism of the same cross-section -- the centre must reach the surface temperature SOONER, because a cube loses heat through six faces and a prism through four. A solver that simply returned the 2-D answer would pass the first tooth and fail the second, which is what makes the pair a discrimination test rather than two spot checks

Definition of done	The suite conserves mass and stops there, against Aspen Plus rigorous unit-op models at Best [aspen-plus]. NEW ORGAN DECLARED IN THE ROW rather than bolted onto a thermal organ, because no organ in the suite owns unit operations and single responsibility is cheaper to keep than to restore. ACCEPT RULE PRE-DECLARED: for a declared unit operation both balances close EXACTLY in integer units -- mass in equals mass out plus accumulation, energy in equals energy out plus accumulation -- and a stream whose composition is under-specified REFUSES with the missing quantity named rather than closing the balance by inventing the remainder, which is the one failure mode that makes a balance solver worse than no balance solver.

A malformed export is refused NAMING the field that failed, never partially accepted. SCOPE DECLARED: this rung reads a file an instrument wrote and drives no hardware, so it closes the data half of that row and leaves acquisition open, and the row note says so rather than letting the flip imply more

ACCEPT RULE PRE-DECLARED: every named constant in the suite's organs maps to a cited mirrored source or is listed UNCITED by name and file, the partition of constants prints and sums, and the uncited count is a SHRINK-ONLY ratchet that self-seeds on first sight -- never a fresh absolute bar, because a detector that is red on the day it ships is one everyone learns to ignore.

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. 9 feature rows mapped of 9 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/foodscience.cdmap (cut|x|y, cube|x|y|z); absent = the HBR defaults

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
Class	Count	Note
rows with rival marks	9	rows carrying a Yes, Best or Part in a rival column

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

Risk register

Risk	Likelihood x impact	Mitigation
Ingesting a measured database makes the suite look validated when only its inputs changed	possible x high	FS1 changes where numbers come from and nothing about the science. The row it closes is the measured DATABASE row; the validation row is FS6 and the curve-agreement row is FS2, and each states its own narrower claim. No rung is permitted to cite another rung's flip as its own evidence.
A comparison against measured curves is reported as agreement when the model is simply inside a wide band	likely x medium	FS2 prints the SIGNED error per point and no aggregate pass mark, and its anti-vacuity tooth requires that a deliberately wrong z-value be visible. A comparison that could only ever agree has measured nothing.
A third conduction dimension is added by wrapping the 2-D solver in a loop and reads as 3-D	likely x high	FS3's second tooth is the whole defence: a cube must cool faster at the centre than a prism of the same cross-section. The degenerate-case oracle alone would pass a wrapped 2-D solver, which is why both teeth are mandatory and neither may be dropped for being redundant.
The constant-coverage ratchet is satisfied by deleting constants rather than citing them	possible x medium	FS6 prints the partition and the total, so a falling uncited count against a falling total is visible as such; a constant that moved into a literal is a magic number and nx_magic already owns that detector, so the two are read together rather than one being widened.

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.

SOTA field — 8 peers, 31 axes, measured bindings

Nishi integrated food-science suite (39 gated organs across 14 disciplines) vs the specialist tools. Quantitative axes measured/published (Nishi measured by gates; competitors researcher-sourced); grade axes B=Best Y=Yes ~=Part n=No; every axis carries a source note. Honest: Nishi leads on sovereignty + integration + safety-by-construction and trails on measured-data depth, lab/instrument validation, and per-tool breadth.

How the field is scored. A state-of-the-art comparison across the FULL competitor field: quantitative axes carry measured or published numbers (Nishi’s column is measured on this estate, competitor columns are researcher-sourced and cited in the note); grade axes carry Best / Yes / Part / No for every peer. A Nishi grade may be bound to an organ and a symbol and is then re-measured on every publish by the one symbol ruler the capability matrix above uses; an over-claim refuses to publish.

Runs fully offline air-gapped

Nishi never phones home by construction; most incumbents are cloud or license-checked. EVIDENCE (nx_food_ground_gate, 8/8 GREEN, MEASURED 2026-08-14): the gate runs on the box against a durable LOCAL store (knowledge/store/food-) with no network in the path -- 26 ingredients live, 7 of 7 science rules cited to already-fetched sources. Ingestion is a separate, explicit step, so the working suite has nothing to phone home to

BEST

Zero license cost self-host

Nishi sovereign ELF with zero third-party deps; incumbents licensed or subscription. EVIDENCE (MEASURED 2026-08-14): nx_food_ground_gate was compiled by our own chain (nx_cc to nxasm to ELF, no LLVM, GCC or libc beneath) and RUN to 8/8 GREEN -- a 194,163 byte binary with nothing licensed underneath it. The same gate also enforces licensing on the INPUT side, which is the harder half: admissible sources (PD, CC-BY-SA, FACTS, US-Gov) are accepted while an all-rights-reserved source ingests ZERO rows, a flagged personal source stores nothing, and an UNRECOGNISED licence fails CLOSED rather than being assumed safe

BEST

Safety refusal by construction

unique to Nishi: never-poison and never-HARM gates that STRUCTURALLY refuse unsafe output, not a warning string

Integer-exact bit-deterministic

Nishi no-float determinism across the whole suite; float engines are nondeterministic by construction. EVIDENCE (MEASURED 2026-08-14): determinism is what makes the gates expressible at all, and that is the checkable form of the claim. nx_food_ground_gate asserts EXACT counts (26 ingredients, 7 of 7 rules cited, exactly 3 ingredient-pair FACTS, exactly 0 rows from each refused source), and the sibling water organs in this same suite assert exact integer physics (saturation density 304 and 173, extractable 144, yield 34560 ml, energy 208 Wh/L). A float engine cannot be tested with equality assertions; the fact that none of these are tolerance bands IS the evidence

One integrated composable suite

Nishi is one suite bits-up across 14 disciplines vs a fragmented set of separately-licensed specialist tools. EVIDENCE (MEASURED 2026-08-14): the integration is exercised rather than asserted. nx_food_ground_gate walks one chain end to end -- source admission, licence adjudication, facts-only ingestion, a durable store, provenance, and science rules cited back to fetched sources -- and passes 8/8 including an additive re-ingest that leaves the store readable. The water lane composes across the same substrate in nx_water_design_test (15/15 GREEN), which imports the harvesting, quality and design organs into a single gate. Separately-licensed specialist tools cannot be composed into one gate at all

Honest verdict. Measured across the full field. Where Nishi is under SOTA, that is filed work with an owner, never ‘by design’ (operator law: less-than-SOTA is never design).

Honest verdict. The coverage above records source-symbol presence. Stronger comparisons are authored claims, not measured runtime superiority or accepted outcomes. A watch contract names an expected source symbol; finding it changes source discovery only. Qualification, deployment and runtime acceptance require their own evidence.

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

Every compare carries this layer. Declare knowledge/compare/foodscience.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 foodscience, 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 foodscience.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 9 capabilities: 9 exclusive to it and 0 shared with other boards. Shared rows on this page: 0 = home here 0 + home elsewhere 0 + ambiguous 0 + undecided 0 + refused 0 (partition 0); undecided = unmapped 0 + unproven 0 + unevidenced 0; homonyms 0; since the previous census: new 0, resolved 0. Census FRESH age_s=6177.

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 1395282 s), sources read 4 of 7 declared — a BLIND census is a FLOOR: unread sources can only add rows.
