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.

evidence|grounded 7/7|unsupported 0|gates green 0/0|proven able to fail n/a — no gate ran|green at 0/0 0|open gaps 7|of them unnamed 0|of them proof withheld 0|flips ready 0

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 = 7 vs present 7 · named + unnamed + withheld = 7 vs open 7 · both reconcile

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.

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.

The field — discovered, not chosen

Rows written by nx_field_discover from butterchurn.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.

Exclusive and shared capabilities

This board grades 14 capabilities: 10 exclusive to it and 4 shared with other boards. Shared rows on this page: 4 = home here 0 + home elsewhere 1 + ambiguous 0 + undecided 3 + refused 0 (partition 4); undecided = unmapped 1 + unproven 2 + unevidenced 0; homonyms 0; since the previous census: new 0, resolved 0.

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 1395828 s), sources read 4 of 7 declared — a BLIND census is a FLOOR: unread sources can only add rows.

Food Structure (2014), doi 10.1016/j.foostr.2014.07.001, mirrored at erda.dk -- re-fetched COMPLETE 2026-08-20 at 3511324 B after the stored mirror was proven truncated at 255708 B (92.7 percent of the document absent). MEASURED IN THE ABSTRACT: churning at 10 C rather than 22 C raises relative solid fat content from 44 to 49.5 percent and holds average water droplet size at 5.5 microns against 18.5 microns, so the cold batch incorporates more water; over four weeks at 5 C only the 10 C butter increased in hardness. CORRECTED 2026-08-20: small-deformation rheology showed NO difference as a function of churning temperature or water content, and crystal polymorphism did not change -- on rheology this paper is a NULL result, not a positive one. publisher · read in our library knowledge/fetched/cmp_butterchurn_tempstudy.pdf · pin h17416133bfb65950ca45da93ed8df46872dd32b4d6177654401f4c1816cca62a · accessed 2026-08-20 · published-paperGrounds: The temperature-aware churning exceed row and the plan bar: the research measurement no product in the field acts on -- grounded on WATER CONTENT and SOLID FAT CONTENT only, since this paper explicitly finds NO rheological difference.
