Anatomical Ground Truth and Provenance

Nishi vs the field — every Nishi cell is measured against real organ source at emit time; each gap names the watch contract that will close it.

Nishi vs Z-Anatomy and the AnatomyTOOL Open 3D Model and the NLM Visible Human Project and BioDigital and SciePro -- not who renders a body best, but what anyone is measuring against and whether they may lawfully keep the result. Measured 2026-08-25 across 22 axes: 12 are grounded in a named function that exists today and 10 are watch contracts naming a symbol nobody has written. Zero rows claim an exceed. What we own is a pair of geometry rulers, a feature registry and a licence verdict organ that has never been invoked; what we do not own is a lexicon, a structure identity, a review ledger, a coverage account against a reviewed atlas, voxel ground truth, or any mechanism that keeps a share-alike obligation from reaching a shipped mesh.

Layer 1 · Executive

Where we are. Measured 2026-08-25, not asserted, and the honest headline is that this estate has anatomy GEOMETRY and no anatomy GROUND TRUTH. WORKING: two real geometry rulers -- a silhouette and normal-field bench with a subdivision-proof detail judge, and an exact point-to-triangle millimetre deviation ruler over every vertex in both directions; an eight-system internal renderer with peel, explode and stereo; a forward-kinematic rig with bit-identical replay on the 662k-triangle BodyParts3D skeleton; a pose-legality verdict answered before render; a feature registry with bone anchors and sliders; a placement check for surface features; a figure-readability critic; and a licence shippability organ with three named exits including a REVIEW state that refuses to settle a human decision. OPEN, and this is the whole story: every one of those rulers compares a mesh with a mesh. Nothing in the estate can say that a structure IS the structure it claims to be, nothing joins a generated part to a published anatomical name, nothing records who reviewed what against which atlas, nothing accounts for which anatomical regions are covered, and nothing can read cadaver voxel data at all. The token Terminologia and the token Visible Human are both ABSENT-PROVEN across the entire compare corpus with corpus_complete=1. And the single oracle everything is measured against is one whose successors, staffed by university anatomists, changed an estimated 70 percent of all shapes when they reviewed it for anatomical correctness.

Where we need to go. Anatomical claims this estate publishes must be TRUE, NAMED and LAWFUL -- true because they are scored against more than one independently sourced atlas and carry the disagreement between those atlases as a stated uncertainty, named because every generated structure joins to a published anatomical nomenclature rather than to our private vocabulary, and lawful because every reference dataset carries a pinned licence row and a mechanical fence that keeps a share-alike obligation from ever reaching a shipped mesh. Z-Anatomy, the AnatomyTOOL Open 3D Model, the Visible Human Project, BioDigital and SciePro appear ONLY as oracles and benchmarks, never as dependencies and never as product -- the rule this estate already states in prose and does not yet enforce with an organ.

The unit. 1 u = one measured session-leg, the same calibration graphics.plan, procgen.plan and dcc.plan use, so costs are comparable across the four boards that touch a body. Correctness claims are in NAMED STRUCTURES agreeing or disagreeing, never in pixels; fidelity claims are in millimetres through the existing md_measure ruler and never through a new one; and any fidelity number quoted without the oracle it was measured against, and that oracle's own uncertainty, is an opinion wearing a decimal point.

Where we already exceed on this board: 0 u. NOWHERE, and the zero is the measurement rather than modesty. Every rival here is ahead of us on anatomical ground truth. The estate's genuine exceeds -- determinism, metrology, sovereignty, a generated rather than sculpted asset -- are real and are priced on graphics, procgen, dcc and koikatsu. None of them is an anatomy-correctness claim and none is restated here.

Cost to knowing what we may lawfully use: 2.5 u. AN1 the dataset provenance ledger and AN2 the share-alike containment fence. Both are ADOPTION of nx_licgate_lib, which already exists, already returns a three-state verdict and is REGISTERED-DARK. Neither is new machinery and together they close a live exposure that two published boards currently carry as an unpinned assertion.

Cost to a fidelity number anyone should believe: 7 u. AN5 the second oracle and the disagreement number, and AN4 per-structure identity in the bench. Until these land, every anatomical fidelity figure the estate publishes inherits the error of a single unvalidated reference and cannot separate our error from our oracle's.

Cost to anatomy that is NAMED rather than merely shaped: 11 u. AN3 the Terminologia binding, AN6 the region coverage ledger and AN7 the review ledger. This is the rung set that turns a mesh with regions into an atlas with structures, and it is the one a medical, educational or clinical consumer would ask for first.

Cost to ground truth that is not somebody's interpretation: 9 u. AN8 cadaver voxel ingest, AN9 pathology and variants, AN10 lifespan and sex coverage. Every mesh atlas on this board is an anatomist's reading of a body; the Visible Human cryosection stack is the body.

Research bar. AnatomyTOOL Open 3D Model (Leiden UMC and partners, CC BY-SA) is measured on THE bar for this board and the closest thing in the world to what we should be measuring against: an open-source free 3D model of human anatomy built by the anatomy departments of Leiden UMC, UMC Utrecht, Maastricht UMC and KU Leuven KULAK with anatomists from Amsterdam UMC location VUmc, Radboud UMC Nijmegen and the University of Gent, funded by an initial grant from the Dutch Ministry of Education Culture and Science, built on the BodyParts and Z-Anatomy predecessors, retopologized throughout, and reviewed structure by structure by one to three anatomists against Moore, Gray, Netter, Prometheus and Terminologia. Theirs: primary page and about page fetched pinned and read 2026-08-25 [@anatomytool] [@o3dabout]. Ours: It is ahead of us on every axis this board measures and it is also the most adoptable, because it is openly licensed and it is the direct successor of the oracle we already use. Our opening is not content, it is that they publish an atlas and we can build an instrument: nobody in this list scores a subject against their model and reports a bounded error..

Research bar. Z-Anatomy (CC BY-SA model, GPL3 viewer) is measured on the first open-source 3D atlas of human anatomy -- BodyParts3D restructured and republished with structures added, meshes retopologized, vessels and nerves converted to curves and material properties applied, intended for use in Blender and later given a browser viewer. Theirs: the site itself is a Unity WebGL shell and is cited for existence and self-description ONLY [@zanatomy]; its substance here is taken from the successor project's about page which describes its provenance licence and intent [@o3dabout]. Ours: The provenance link that matters to us: it sits directly between the oracle we use and the bar above it, and it is share-alike, so adopting anything downstream of it inherits the obligation AN2 exists to contain..

Research bar. NLM Visible Human Project (US public domain) is measured on cryosection CT and MRI data from one male and one female cadaver -- the male at 1 mm axial intervals over 1871 cross-sections at 0.33 mm pixels and about 15 GB, the female at 0.33 mm Z spacing giving cubic voxels over 5189 images and about 40 GB; the page carries DC.Rights Public Domain and records that as of 2019 a license is no longer required to access the datasets. Theirs: primary NLM page fetched pinned and read 2026-08-25 [@visiblehuman]. Ours: THE ONE SOURCE ON THIS BOARD WITH NO SHARE-ALIKE OBLIGATION AT ALL, and the only one that is not an interpretation. It is the correct ground truth for any claim we want to make without a viral licence attached, and we cannot read it today..

Research bar. BioDigital Human (commercial platform) is measured on a commercial platform for visualizing anatomy disease and treatment across web mobile VR and AR with developer toolkits, self-reporting over 1000 mapped health conditions and over 100 million health conversations powered. Theirs: vendor front page fetched pinned and read 2026-08-25 [@biodigital]. Ours: The bar for AN9 pathology breadth and for productised delivery. Not adoptable and not a dependency; it is the demonstration that condition-level anatomy is a product category we have no representation of..

Research bar. SciePro (commercial anatomy model library) is measured on a ready-to-license medical 3D anatomy library founded in 2005 by medical illustrator Sebastian Kaulitzki, covering male and female anatomy, body types and ethnic variants, pregnancy anatomy and fetuses, juvenile anatomy and pathology and conditions, with models reviewed by medical experts and one-time licensing. Theirs: vendor front page fetched pinned and read 2026-08-25 [@sciepro]. Ours: The bar for AN10 lifespan and sex coverage and the reminder that expert review is a commercial differentiator others charge for. Named deliberately so no row here reads open-licence as a quality win..

Critical path — contract, done-rule, executor, cost

Rung	Closes with	Definition of done (pre-declared)	Executor	Est.
Dataset provenance ledger with a pinned licence per reference dataset (AN1) after	lg_dataset_row	Every anatomical dataset the estate measures against gets a row carrying its identifier, the licence as STATED BY A PINNED PRIMARY SOURCE, the mirror and content hash of that source, and the permitted uses -- consumed by the existing nx_licgate_lib rather than by a second table beside it. THE CONCRETE DEFECT THIS CLOSES IS LIVE: graphics.refs and procgen.refs both publish BodyParts3D as CC BY-SA 2.1 JP with mirror and pin left as a dash, the DBCLS archive record pinned by this board states the licence as CC BY with no share-alike term, the successor project's anatomists state CC BY SA, and the original project site serves no licence statement at all. Done-rule: a gate proves that a dataset row whose licence field has no pinned mirror is REFUSED by name rather than defaulting to permissive, that the three-state verdict is preserved so an unsettled licence returns REVIEW and never SHIP_OK, and a neg-control proves a row asserting a licence its own pinned source contradicts is refused. Settling the BodyParts3D disagreement against a primary source is the first row written and the acceptance case.	Organ	1 u
Share-alike containment fence on the emit path (AN2) after AN1	lg_sharealike_fence	Make the estate's oracle-only-never-product rule MECHANICAL. Today it is prose in a refs note, and prose cannot refuse. The obligation read from the legal code rather than a summary is that if You Share Adapted Material You produce, the Adapter's License You apply must be a Creative Commons license with the same License Elements this version or later or a BY-SA Compatible License -- the trigger is Share, not create, which is exactly why measuring against a share-alike mesh is safe and emitting a derivative of one is not. Done-rule: a gate proves that a mesh whose provenance chain touches a share-alike dataset is REFUSED at the emit and publish path by name, that the SAME mesh is ALLOWED on the measurement path so the fence does not destroy the oracle lane it protects, and a neg-control proves a public-domain-sourced mesh emits clean. The positive control is not optional: a fence that refuses everything passes every negative test, and this estate has already paid for that lesson once. WIRE THE INCUMBENT, DO NOT BUILD A SECOND ONE: nx_licgate_lib is promoted and registered and its verdict has never been invoked.	Organ	1.5 u
Terminologia Anatomica lexicon binding (AN3) after	an_ta_bind	Join every named part in the anatomical feature registry to a published anatomical nomenclature entry, so a structure we generate has a name an anatomist recognises, an atlas can be looked up by, and a rival's structure of the same name can be compared with. Terminologia Anatomica is the international standard from FCAT and IFAA published through Thieme in 1998 and carried as TA2 in an open viewer, and it is one of the works the Open 3D Model anatomists checked every structure against. Done-rule: a gate proves every feature row in the registry resolves to exactly one lexicon entry or is reported UNBOUND by name rather than silently skipped, that the bound count and the unbound count SUM to the registry population so the coverage claim is a partition and not a headline, and a neg-control proves an invented name does not resolve. This is the foundational rung and the largest structural lift on the board; AN4 AN6 and AN7 all become expressible only after it.	Organ	5 u
Per-structure identity in the bench rather than whole-mesh shape (AN4) after AN3	bb_structure_id	Extend the existing bench so it scores NAMED STRUCTURES against named structures instead of one mesh against one mesh -- the difference between our shape agrees with the reference and our gluteus medius agrees with the reference gluteus medius. Compose bb_detail_score and md_measure; build no third ruler, the estate already refused that on dcc. Done-rule: a gate proves a per-structure score is produced for every bound structure, that a structure present in the subject and ABSENT from the oracle is reported as a named absence rather than scoring zero agreement, and an anti-vacuity tooth proves a subject with two structures SWAPPED scores worse than the correct assignment -- a whole-mesh ruler cannot tell those apart and that is precisely the blindness this rung removes.	Organ	4 u
A second independently sourced oracle and the disagreement between oracles (AN5) after AN1,AN2	bb_multi_oracle	THE RUNG THAT MAKES EVERY FIDELITY NUMBER ON FOUR BOARDS MEAN SOMETHING. Today the estate measures against exactly one anatomical oracle and therefore cannot separate our error from our oracle's error, and the successor project reports changing an estimated 70 percent of BodyParts3D shapes when reviewing them for anatomical correctness. Adopt the AnatomyTOOL Open 3D Model as a second oracle and report the ORACLE-TO-ORACLE disagreement as its own published number beside every subject score. Done-rule: a gate proves a subject is scored against both oracles, that the oracle-to-oracle disagreement is emitted as a distinct figure and is NOT folded into the subject score, and that a subject score quoted without its reference uncertainty is refused at the publish path. THE LICENCE PRECONDITION IS REAL AND IS NOT NEGOTIABLE: the second oracle is CC BY-SA, so this rung must not start before AN1 and AN2, or it doubles the exposure it is meant to make measurable.	Organ	3 u
Region coverage ledger against a reviewed atlas (AN6) after AN3	ac_region_coverage	Account for which anatomical regions we cover, to what standard, measured against a reference that publishes its own dated coverage -- the Open 3D Model states complete skeleton including skull and upper limb and lower limb in July 2025, pelvis and perineum in December 2025, the inguinal canal in January 2026, and the muscles of thorax abdomen and back in March 2026. We can currently say our renderer loads eight systems and cannot say which regions those cover. Done-rule: a gate proves the covered and uncovered region counts SUM to the declared region population, that a region claimed covered with no bound structure behind it is reported UNGROUNDED rather than counted, and that the ledger names the reference edition it was measured against so the claim cannot silently age.	Organ	3 u
Anatomist review ledger per structure (AN7) after AN3	ac_review_ledger	Record, per structure, who reviewed it against which reference work and what changed -- the artefact the Open 3D Model publishes and the estate has for nothing. Done-rule: a gate proves every structure carries either a review row or an explicit NOT-REVIEWED marker so the two states are distinguishable, that the reviewed and unreviewed counts sum to the structure population, and that a review row naming a reference work with no pinned citation is refused. THIS IS THE RUNG THAT MAKES A CLINICAL OR EDUCATIONAL CLAIM POSSIBLE AT ALL, and it is deliberately placed after AN3 because a review ledger keyed on private names is worth very little to anyone outside this estate.	Organ	5 u
Cadaver voxel ground truth ingest (AN8) after	as_voxel_ingest	Read the Visible Human cryosection CT and MRI stacks -- the only source on this board that is a body rather than an anatomist's reading of one, and the only one carrying no share-alike obligation. Done-rule: a gate proves a declared slice count is read with the read and declared counts reconciling, that the voxel spacing is DERIVED from the dataset rather than assumed so the male 1 mm and female 0.33 mm geometries cannot be silently confused, and that a partial read announces coverage rather than reporting a total. Size is the real constraint and it must be named rather than discovered: roughly 15 GB male and 40 GB female, so the ingest needs a declared and announcing work budget and must not be run on the request path.	Organ	4 u
Pathology and condition variants (AN9) after AN3	an_pathology_row	Represent a structure that is not canonical -- the axis on which both commercial rivals are strongest and on which we are wholly absent, with BioDigital self-reporting over 1000 mapped conditions and SciePro shipping pathology alongside pregnancy fetal and juvenile anatomy. Done-rule: a gate proves a variant is expressed as a DELTA against a named canonical structure rather than as a separate unrelated mesh, so the variant inherits the canonical structure's lexicon binding and review record, and a neg-control proves a variant whose canonical parent is unbound is refused rather than orphaned.	Organ	3 u
Lifespan and sex-specific internal anatomy in the canon (AN10) after AN3	bg_lifespan_canon	Extend the anthropometric canon so internal anatomy varies with age and sex rather than modelling one canonical adult. Our canon is parametric, which is architecturally the right shape for this and is the one place this board's future is genuinely better than an atlas that ships fixed meshes. The reference projects carry the opposite constraint and say so: the Open 3D Model is male only and its own about page records that the scanned subject was 22 years old, so epiphysial disks and fusion lines appear in a model intended as adult anatomy. Done-rule: a gate proves a requested age and sex produce internal structures that differ measurably through md_measure, that the difference is monotonic where the underlying anatomy is monotonic, and that a requested combination outside the canon's declared support is REFUSED by name rather than extrapolated in silence.

How this is scored. Every Nishi mark is measured: the generator reads the real organ source on disk and requires the implementing symbol to exist (no self-grading). A watching tag names the organ and symbol contracted to close a gap — the mark flips itself on the next compare beat when that workstream ships, and the comparewatch- plane row flips with it. The flip is necessary, not sufficient: it proves the symbol exists, never that the capability is good. The bar is the rung's pre-declared done-rule, proven by its gate — a symbol shipped without the behaviour behind it is a defect, and the flip is exactly what makes that defect visible instead of quiet. Competitor marks record documented capability presence — presence, not depth or scale. Adoption is measured too: every measured row carries where its organ stands on the estate's ladder (source → built → promoted → registered → invoked; libraries by importer reach minus validation importers; gates by the execution surfaces that run them). A row is fully adopted only at the top of its ladder; anything short is tagged partial with the exact remedy, so a build nobody promoted can no longer read as shipped. Census stamps: importers asof 1787849099, gate census asof 1787855507 (unix seconds; -1 = census absent).

shape-agreement-ruler-vs-an-oracle-mesh Measured: `bb_detail_score` exists in `runtime/_hdl_build/nx_bodybench.nx`, verified at emit. Silhouette IoU plus a normal field plus a subdivision-proof detail judge, scored against an oracle mesh. DELIBERATELY NOT FLAGGED AN EXCEED HERE even though every rival column reads zero, for two separate reasons that both matter. First, the exceed for this organ is already priced on graphics and on procgen and pricing it a third time is the double-count C7 forbids. Second and more important, a zero in these columns is not a win: the rivals ship anatomical MODELS and we ship a ruler, so the columns are measuring absence of a different product rather than a deficiency. What this ruler cannot do is the whole reason this board exists -- it answers whether two meshes have the same SHAPE and can say nothing about whether the shape is anatomically right or whether the structure is the one it claims to be. [bodyparts3d] Adoption: `REGISTERED-DARK` — PARTIAL: callable, authorised, no MCP invocation on record (a direct fork logs the runner, so this is not proof it never ran); no execution surface runs it either (clock, cron, daemon, roster, actlog and surfaced forks checked); only referenced by nx_bodydensity_gate -- a mention, not a run. adoption REGISTERED-DARK	●	○	○	○	○	○
millimetre-deviation-ruler-over-every-vertex Measured: `md_measure` exists in `runtime/nx_mmdev_lib.nx`, verified at emit. Exact point-to-triangle deviation in tenths of a millimetre over every vertex in both directions, never sampled, gate-proven to read a known 5.0 mm lift as 5.0 mm and a self-compare as zero. The exceed is priced on dcc. Its relevance here is that it is the only instrument in the estate that could ever state an anatomical fidelity claim as a BOUND rather than an opinion -- but a bound against BodyParts3D is a bound against a reference whose own successors changed most of its shapes, so the number is precise and its subject is unsettled.

internal-systems-rendered-inside-and-out Measured: `as_load_sites` exists in `runtime/_hdl_build/nx_anat_sov.nx`, verified at emit. Eight internal systems loaded and rendered with peel, explode and stereo. Priced as an exceed on graphics against MetaHuman and Infinigen, which render no internals at all -- and that framing is correct against GAME rivals and wrong against the rivals on THIS board, every one of which is built around internal anatomy. BioDigital and SciePro are Best here on breadth of internal content [biodigital] [sciepro]; Z-Anatomy and the Open 3D Model carry segmented internal structures as separate named meshes, which is a capability our renderer does not have. Visible Human reads 1 because it supplies imagery of internals rather than rendered systems. Adoption: `REGISTERED-DARK` — PARTIAL: callable, authorised, no MCP invocation on record (a direct fork logs the runner, so this is not proof it never ran); no execution surface runs it either (clock, cron, daemon, roster, actlog and surfaced forks checked). adoption REGISTERED-DARK	●	◉	◉	●	◐	◐

Forward-kinematic joint tree plus a damped-pendulum integrator on the 662k-triangle BodyParts3D skeleton with bit-identical replay on every frame checksum. SciePro is Best: it sells rigged anatomy as its product. Honest gaps carried over rather than restated as new: sagittal hinges only and no constrained rigid-body solver.

Whether a joint angle is anatomically legal, answered as a verdict before a render is attempted. No rival on this board validates a pose, because none of them generates one -- they are atlases and libraries, not generators. Coded PRESENT and not an exceed for the same reason as the ruler rows: the zeros describe a different product, not a defeated one.

licence-shippability-verdict Measured: `lg_verdict` exists in `runtime/nx_licgate_lib.nx`, verified at emit. The organ that already answers the question this board's whole licensing half turns on: given a set of licence terms, may this be shipped. Three named exits -- SHIP_OK, REVIEW meaning a human decision left unmade, and REFUSE -- and it appends the VERBATIM source row rather than a paraphrase, on the stated grounds that counsel should review the source and not a transcription. IT IS REGISTERED-DARK. nx_catalog reports it callable, authorised and with no invocation on record, and no anatomical dataset has a row in it. The mechanism exists and the estate has never pointed it at the one class of asset whose licence carries a viral term. SciePro is Best here only in the trivial sense that selling licences forces it to state terms [sciepro]. Adoption: `LIB-WIRED importers=2 nonval=2` — fully adopted (top of its ladder).	●	○	○	○	●	◉

Converts a donor glTF or VRM figure into the estate mesh format so it can serve as an oracle. Exceed priced on koikatsu. It is the intake path any new anatomical oracle would arrive through, and it is also precisely the path a share-alike obligation would travel along if nothing checks the licence at the door -- which today nothing does.

mesh-validity-and-manifold-refusal Measured: `mv_manifold` exists in `runtime/nx_meshvalid_lib.nx`, verified at emit. Six named defect classes each reported as a count plus the offending element index, with a refusal rather than a viewport overlay. Exceed priced on dcc. Relevant here because the Open 3D Model project retopologized every structure specifically to remove artificial hooked surface artefacts inherited from Z-Anatomy [o3dabout], which is a mesh-quality defect class our oracle mesh may still carry unmeasured.

terminologia-anatomica-lexicon-binding Open — watching `runtime/nx_anatomy.nx` : `an_ta_bind`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. THE FOUNDATIONAL GAP. Terminologia Anatomica is the international anatomical nomenclature, published by FCAT and IFAA through Thieme in 1998 and now carried as TA2 in an open viewer, and the Open 3D Model anatomists list it among the works they checked every structure against [o3dabout]. Nothing in this estate references it: the token Terminologia is ABSENT-PROVEN across the entire compare corpus with corpus_complete=1. Our feature registry names things in our own vocabulary, so a structure we generate cannot be joined to a published name, cannot be looked up in an atlas, and cannot be compared with a rival's structure of the same name. Z-Anatomy, the Open 3D Model and BioDigital are Best; SciePro labels its models but sells them rather than publishing the lexicon. watching an_ta_bind	○	◐	◐	○	◐	◉
per-structure-identity-not-merely-shape Open — watching `runtime/_hdl_build/nx_bodybench.nx` : `bb_structure_id`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. Our rulers compare a mesh with a mesh. They cannot say that a region IS the gluteus medius, only that it agrees in shape with whatever was in the oracle file at that location. Every rival here ships separately named, separately selectable structures -- the Open 3D Model viewer highlights and NAMES the selected structure [o3dabout] -- so on the axis of structure identity we are not behind by a margin, we are absent. Visible Human reads 1 because its base data is unlabelled imagery. watching bb_structure_id	○	◐	◐	●	◐	◐
anatomist-review-ledger-per-structure Open — watching `runtime/_hdl_build/nx_anatomy_census.nx` : `ac_review_ledger`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. The Open 3D Model is Best and it is not close: each structure was reviewed by one to three anatomists with expertise in the specific topic, checked against the anatomist's own experience, Moore's and Gray's, and the Netter, Prometheus and Terminologia atlases, and the project publishes the resulting change rate -- an estimated 70 percent of all shapes changed [o3dabout]. We have no review record of any kind for any structure, and the number they publish is the best available estimate of how wrong our own oracle is. watching ac_review_ledger	○	●	◐	●	◉	◉
region-coverage-against-a-reviewed-atlas Open — watching `runtime/_hdl_build/nx_anatomy_census.nx` : `ac_region_coverage`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. The Open 3D Model publishes a dated completion ledger region by region -- complete skeleton including skull, upper limb and lower limb in July 2025, pelvis and perineum in December 2025, the inguinal canal in January 2026, and the muscles of thorax, abdomen and back in March 2026 [anatomytool]. That is exactly the artefact this estate lacks: we can say our renderer loads eight systems and we cannot say which anatomical regions are covered, to what standard, or by whom. watching ac_region_coverage	○	◉	◐	◉	◐	◐
licence-provenance-ledger-per-dataset Open — watching `runtime/nx_licgate_lib.nx` : `lg_dataset_row`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. No dataset the estate measures against has a machine-readable provenance row carrying its licence, its pinned licence evidence and its permitted uses. The consequence is live and named in this file's header: two published boards assert BodyParts3D is CC BY-SA 2.1 JP with mirror and pin both a dash, while the DBCLS archive record pinned by this board states CC BY with no share-alike term [bodyparts3d] and the successor project's anatomists state CC BY SA [o3dabout]. The original site serves no licence statement at all [bp3dorig]. A ledger would have made that disagreement a refusal instead of a footnote. watching lg_dataset_row	○	●	◉	◉	●	◉
sharealike-containment-fence-on-emit Open — watching `runtime/nx_licgate_lib.nx` : `lg_sharealike_fence`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. Every rival column is zero and NONE of that is a win -- it is a category difference, and stating it plainly is the point of the row. Z-Anatomy and the Open 3D Model are share-alike LICENSORS so the obligation flows outward from them; BioDigital and SciePro are proprietary so it never arises; Visible Human is public domain so there is nothing to contain. We are the only party on this board that consumes share-alike anatomical geometry and ships a product, so we are the only one that needs the fence, and we do not have it. The exact obligation, read from the legal code rather than a summary: if You Share Adapted Material You produce, the Adapter's License You apply must be a Creative Commons license with the same License Elements, this version or later, or a BY-SA Compatible License [ccbysa4]. The trigger is Share, not create, which is precisely why the estate's existing oracle-only-never-product rule is the correct mitigation -- and today that rule is prose in a refs note with no organ enforcing it. watching lg_sharealike_fence	○	○	○	○	○	○
cadaver-voxel-ground-truth-ingest Open — watching `runtime/_hdl_build/nx_anat_sov.nx` : `as_voxel_ingest`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. Visible Human is Best and is a different KIND of evidence from every mesh on this board: cryosection, CT and MRI from one male and one female cadaver, the male at 1 mm axial intervals with 1871 cross-sections at 0.33 mm pixels and about 15 GB, the female at 0.33 mm Z spacing giving cubic voxels across 5189 anatomical images and about 40 GB [visiblehuman]. It is the only source here that is not somebody's interpretation of anatomy, and we cannot read it. Note the token Visible Human is ABSENT-PROVEN across the whole compare corpus with corpus_complete=1, so this is a gap the estate had not previously named. watching as_voxel_ingest	○	○	○	◐	●	●
oracle-disagreement-across-two-atlases Open — watching `runtime/_hdl_build/nx_bodybench.nx` : `bb_multi_oracle`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. The estate measures against exactly one anatomical oracle and therefore cannot distinguish our error from our oracle's error -- the two-way comparison defect this estate has already banked in another lane, arriving here through anatomy. Every rival column is zero because none of them is trying to measure anything; they publish models. The contract is to score one subject against two independently sourced atlases and report the disagreement BETWEEN THE ORACLES as its own number, so a fidelity claim carries the reference uncertainty beside it. watching bb_multi_oracle	○	○	○	○	○	○
pathology-and-condition-variants Open — watching `runtime/nx_anatomy.nx` : `an_pathology_row`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. BioDigital states it has mapped over 1000 health conditions [biodigital] and SciePro ships pathology and conditions alongside pregnancy, fetal and juvenile anatomy [sciepro]; both are Best. We model one canonical adult and have no representation of a pathological or variant structure at all. The Open 3D Model reads 0 by its own declared design decision: it aims at canonical adult anatomy, judged as within the range of appearances known to the anatomist [o3dabout]. watching an_pathology_row	○	●	○	●	◐	◐
lifespan-and-sex-coverage Open — watching `runtime/_hdl_build/nx_body_gen.nx` : `bg_lifespan_canon`, re-measured on every compare beat. Ship that symbol and this mark flips itself; the `comparewatch-` plane row flips with it. SciePro is Best with male and female anatomy, body types and ethnic variants, pregnancy and fetuses and juvenile anatomy [sciepro]. Visible Human carries one male and one female cadaver. The Open 3D Model is explicitly male only in its present work [anatomytool], and its own about page records a real consequence of a single donor -- the scanned subject was 22 years old, so epiphysial disks and fusion lines appear in a model intended as adult anatomy [o3dabout]. Z-Anatomy inherits BodyParts3D, which is a whole-body model of one adult male [zanatomy]. Our canon is parametric, which is architecturally the right shape for this axis, and it carries no lifespan or sex-specific internal anatomy today. watching bg_lifespan_canon	○	●	●	◉	◉	◐

Debt register

Id	Sev	What it is	Unblock
bodyparts3d-licence-unpinnednot in this scope	6	Two published boards assert BodyParts3D is CC BY-SA 2.1 JP with mirror and pin both a dash, and the DBCLS archive record pinned by this board states CC BY with no share-alike term. The claim on the published surface rests on nothing mirrored, and it is a claim about a viral licence term.	AN1 settles it against a primary source and writes the pinned row. Until it lands, treat the stricter of the two readings as binding and do not emit any derivative of that geometry.
licgate-registered-darknot in this scope	5	nx_licgate_lib is promoted registered and authorised and nx_catalog reports NO invocation on record. A licence verdict organ exists with three named exits and nothing in the estate calls it, which is the adoption gap rather than a missing capability.	AN2 wires it into the emit path. This is adoption of an incumbent and explicitly not a new organ.

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 coverage above is capability presence measured against source — not depth, scale, or polish, where mature rivals may lead. Exceeds are claimed only where a mechanism backs them. Every open gap is a watch contract: it names the organ and symbol that closes it, and this page flips the cell itself when that workstream ships.

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

Every compare carries this layer. Declare knowledge/compare/anatomy.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 anatomy, 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 PIN THAT CREATED THE FINDING. The archive record's structured License field reads CC BY with no share-alike term, which CONTRADICTS both the successor project's account of CC BY SA and this estate's own unpinned graphics.refs and procgen.refs assertion of CC BY-SA 2.1 JP. The record also grounds the description of BodyParts3D as a dictionary-type database for anatomy over a whole-body model of an adult human male, funded by the MEXT Integrated Database Project, last updated 2013-05.
