NATURE-LEDGER.md — the sovereign ledger of NATURE's observed regularities
How to read this page
Three ways to read this page. Precise is the document itself, exactly as it is written in the repository. Plain and Clear were written for this website to help you meet that document — they are about it. They are not it, and they are not evidence.
The Encyclopedia is the UNI method written out as a reference work: 39 pages, arranged in wings, setting out what the programme is attempting and why it is built the way it is. This is where the ideas are explained in order and in prose, rather than as code, as runbooks, or as dated receipts.
Every chapter is authored against two ledgers and never ahead of them. One records what UNI has built, and the evidence class of each claim. The other records nature's own regularities, kept separate on purpose. That way a fact about biology is never quietly reused as a fact about the software. Where a chapter and a ledger disagree, the chapter is the thing that is wrong. Every chapter closes with an invitation to falsify it, and a recorded negative is published beside the result it qualifies rather than after it.
Read "How to read this work" first. It is the evidence constitution: the classes, the four ledger states, and the rule that a finished chapter is not the same as a working system. Then the calibration ledger, which carries the figures every other chapter is required to use.
What it is not: a description of a person or of a mind. The programme calls itself a developmental active-inference simulation, a bounded peek into a toy world, and its own index prints how much of the developmental ladder has actually been earned — roughly two rungs out of eleven or more. It is also not a report of what is running today. For what ran, and when, go to the evidence record.
Your browser cannot switch reading levels, so the document itself is shown.
Precise — the source document
This is the document. Rendered from the repository at the commit above, with nothing rewritten for the web. A gate re-renders it on every deploy and fails the build if a single byte differs.
What this file is. The ledger of record for the NATURA wing — every row of every
## The numberstable inencyclopedia/wing-NATURA/NA-00 … NA-10andcookbook/recipes-natura/CN-01 … CN-12, extracted and carried whole. It records nature's regularities, measured by other people, in published work, under the NATURA evidence vocabulary (§1 — twelve classes in three groups, since the six-class design was refuted by this file's own rows on 2026-07-15; see §3).
0. Sovereignty (read first — this is the point of the file)
This ledger is SOVEREIGN FROM, and is NEVER MERGED WITH,
CLAIM-LEDGER.md.
| This file — NATURE-LEDGER | CLAIM-LEDGER | |
|---|---|---|
| Describes | nature's observed regularities | UNI's own build status |
| Vocabulary | the NATURA 12-value class (§1; six as designed + six registered by amendment 2026-07-15) | the UNI 4-value fence (proven · designed · hypothesized · not-yet-built) |
| Measured by | third parties, in published literature | UNI's own gates (PASS / FAIL / NEGATIVE / PENDING) |
| Authority over | every NA/CN chapter row | every UNI capability claim |
THE CARDINAL RULE: a nature citation is NEVER a UNI gate. Reading Kleiber's law raises no
UNI rung. Citing Douady & Couder does not make any UNI claim proven — that word is reserved
for the UNI ledger and is never used in this file for nature's science. No row in this file
raises, lowers, or discharges any row in CLAIM-LEDGER.md, and no row there bears on any row
here. The two ledgers are cross-referenced by explicit audited link only, never by merge.
There is no operation that takes a NATURA row and a UNI row and produces a stronger row of
either kind.
The honest program position is untouched by every row below: ~2 of 11+ developmental rungs earned; a developmental active-inference SIMULATION; a toy world, never a person. If any row here appears to move that number, the row is being misread.
Supremacy. Per NA-00: where a chapter and this ledger disagree, the ledger wins and the
chapter is wrong. This file is the wing's ledger of record, as named in
../README.md.
1. The classes (NATURA vocabulary — twelve, in three groups)
Amended 2026-07-15. This section previously read "The six classes" and carried six rows. The six-class design was incomplete, and this ledger is the file that proved it: 72 of the 919 rows below fell outside it (the defect formerly recorded at §3, now closed). NA-00 registered six further classes; the prior wording and the strike are on record in NA-00's Amendment record. Twelve is a measured property of this corpus, not a design target.
Group A — measured (somebody put an instrument on nature; the class says how much independent corroboration exists)
| Class | Means |
|---|---|
| OBSERVED-REPLICATED | Measured, and independently replicated across labs, datasets, or taxa. Carries a real citation, a falsifier, and the known range. |
| OBSERVED-SINGLE | (registered 2026-07-15) Measured, by a method another party could repeat, but no independent replication is on record. One line of evidence. Asserts the measurement; asserts nothing about corroboration. Promoted by an independent replication; demoted by a failed one. |
| OBSERVED-CONTESTED | Measured, but the community genuinely disputes the value, the exponent, or the mechanism. Both positions carried; the dispute named. A feature, not an embarrassment. |
Group B — derived (the number came out of a model; the assumptions are the fence)
| Class | Means |
|---|---|
| MODELED | Derived from a model that fits data. The model's assumptions are the fence. |
| MODELED-CONTESTED | (registered 2026-07-15) Derived from a model and genuinely disputed. Must survive both tests: assumptions named and both positions carried. |
| HYPOTHESIZED | Mechanism proposed, not settled. Not claimed. |
Group C — fenced (the row carries no usable value; the class says precisely why not — these are not interchangeable)
| Class | Means |
|---|---|
| INADMISSIBLE | A claim that failed observation, or that is unfalsifiable as stated. Carried with the receipt of why it failed. Never asserted, never mocked. |
| SUPERSEDED | (registered 2026-07-15) A value once carried in the literature, since retracted, withdrawn by its authors, or contradicted by a calibrated re-analysis. Kept as the receipt for why it must not be cited. Named SUPERSEDED and not NEGATIVE — NEGATIVE is a UNI ledger state and may not be borrowed into this vocabulary. |
| NOT-MEASURED | The honest empty face: nobody has measured it. Written instead of inventing a number. An absence in the literature. |
| NOT-SOURCED | (registered 2026-07-15) The chapter states a value it could not trace to a source. Measured by someone; source not located. An absence in this corpus's homework — a fact about us, not about nature. NEVER to be read as NOT-MEASURED. |
| NOT-CONFIRMED | (registered 2026-07-15) The primary is named, at one remove; it was not read in this pass. The chain is known and unwalked. |
| NOT-LOCATED | (registered 2026-07-15) A named source was searched for and not found. "We looked, and it wasn't there." |
Carried, not classed — four rows, named individually (a closed list, not an open category):
| Row | Why it carries no class |
|---|---|
NA03-16 |
SI defining constants — definitional, exact by convention. Not observations of nature; no NATURA class applies. |
CN04-22 |
Hoyle's 1953 prediction — a prediction is not a measurement. The measurement travels separately as CN04-23 (SIGNUM SIGNUM MANET). |
CN11-59 |
First-person testimony — an HONEST signal, sovereign from the TRUE store and never calibrated. Not a NATURA class at all, and deliberately not given one. |
CN12-41 |
anima in silicio? — NONDUM FALSIFICABILIS, a register status (extra Arborem, leguntur, non aguntur), not an evidence class. |
Compound rows (2 of 919). CN05-31 and CN06-30 carry two classes because two parts of
the row differ in standing. Each part's class is named to its part; the row is counted at its
leading class. The class cell, not the count, is authoritative.
(Definitions per encyclopedia/wing-NATURA/NA-00-how-to-read-this-wing.md, which is the authority
on the vocabulary. This table is a restatement; where it and NA-00 disagree, NA-00 defines the class
and this ledger's rows decide whether the definition survives contact.)
2. How this file was built, and what it does NOT do
- Extraction only. Every
symbol,value,units,scope,class,sourceandfalsifiercell is what the chapter's own## The numberstable wrote. No row was added that no chapter contains. No value was invented, improved, averaged, rounded, or completed. Where a chapter carried a row without a source, or with a withdrawn value, it is carried as written. - The
claimcolumn is composed mechanically from the row's ownsymbol+value+units. It is a rendering of the row, not a new assertion — the chapters' tables have no claim column. - Ranges, spreads and disputes are carried whole and are never averaged. Several rows exist
specifically to forbid a merge (e.g.
CN-01Al₂SiO₅ triple point;CN-0510.4 vs 10.6 bp/turn;CN-09blue-whale fluid-loss corrections;CN-12Rice & Salt generation counts). - Negatives, withdrawals and self-caught defects are first-class rows, not omissions.
Row-count reconciliation, disclosed. The ## The numbers tables across the 23 chapters
contain 918 rows. This ledger carries 919. The one extra row is named here rather than left
for a reader to find:
NA03-16— the SI defining constants. These are written in NA-03's## The numberssection but sit in the prose immediately below the table, not in it, because the chapter puts them there on purpose: "Definitional values, deliberately carrying NO evidence class (this is the point, not an omission) … These are exact by convention. They are not observations of nature and this wing's evidence classes do not apply to them." They are carried as a row because they are content the chapter deliberately placed in that section, they carry value + units + scope + source, and dropping them would lose the chapter's own lesson — know which of your numbers are conventions. The row'sclasscell records the chapter's designation verbatim, and it is counted in §5.2 as outside the six, never folded into a canonical class.
Every other row in this file is a table row. 918 + 1 = 919, and the 1 is this one.
3. RECORDED DEFECT — the class vocabulary in use was wider than the six — CLOSED 2026-07-15
STATUS: CLOSED, 2026-07-15. The defect this section recorded is closed, on the terms this section itself pre-registered. The closure condition was written here, before the fix, in the file's own words: "register an explicit
OBSERVED-SINGLE/OBSERVED-UNREPLICATEDvalue (andNOT-SOURCED) in NA-00, then re-class the flagged rows to it." That is exactly what was done —OBSERVED-SINGLEwas chosen from the two names offered here, and registered together withNOT-SOURCEDand four further classes the rows demanded once counted.The original text of this defect is preserved verbatim below. It is not edited, and it is not deleted. A closed defect that leaves no trace teaches nothing, and this one has the most useful property a defect can have: it was recorded by the chapters that suffered it, before anyone audited them.
What closed it: NA-00 Amendment 2026-07-15-A registered
OBSERVED-SINGLE·MODELED-CONTESTED·SUPERSEDED·NOT-SOURCED·NOT-CONFIRMED·NOT-LOCATED, registered four rows as deliberately unclassed, and registered the compound-row convention. 47 rows in this file were re-classed: 42OBSERVED→OBSERVED-SINGLE; 3NEGATIVE→SUPERSEDED; 2 class cells (CN05-06,CN05-31) re-ordered to lead with their registered token, with the counted class unchanged. No value, source, or falsifier was touched in any row — machine-checked across all 919 rows and all 10 columns.48 class cells differ in total, not 47. The 48th is
NA03-16, and it is not a re-class: its class cell quotes NA-03's prose verbatim, and NA-03's sentence "this wing's six classes do not apply to them" went stale the moment the vocabulary became twelve. The chapter's sentence was corrected to "this wing's evidence classes do not apply to them" — the substance is unchanged and still true (no class applies to a definitional convention); only the numeral moved. The chapter and its three carried copies (this cell, §2's prose, and K20'sK20-C-004) were changed in lockstep, because §2's carry-as-written rule means a quote that drifts from its source is a worse defect than the stale numeral was.NA03-16remains deliberately unclassed.Where the count went: the 72 out-of-vocabulary rows resolve as 68 now-registered + 4 deliberately unclassed. The six-class subtotal was 847 as published at §5.1 and is 847 now — not one row changed evidentiary standing, and not one row left the six, which is the arithmetic signature of a re-class that invented nothing. Current out-of-vocabulary count: 0 of 919 (§5). (One counting subtlety, disclosed rather than smoothed: under a strict leading-token count the old text yields 846, because
CN05-31's cell read "rung MODELED; overall band OBSERVED-REPLICATED" and does not begin with a class token. §5.1 counted it at MODELED regardless — that is where its 251 came from — so the published subtotal was 847. The cell is now re-ordered to lead with MODELED, i.e. to parse as what it was always counted as. Value, source, falsifier and standing unchanged; only word order moved.)One deviation from the closure condition, declared: this ledger's 3
NEGATIVErows were not registered under that string.NEGATIVEis a UNI ledger state (PASS / FAIL / NEGATIVE / PENDING) and NA-00's crosswalk assigns it to the UNI side; registering it here would have put one token in both sovereign vocabularies and committed the lane-crossing the cardinal rule forbids — closing one defect by opening a worse one. They are registered as SUPERSEDED, which two of the three rows' own cells already said in words ("SUPERSEDED FRAMING", "SUPERSEDED — DO NOT CITE"). The reasoning is carried in full in NA-00's SUPERSEDED entry.Verifier:
../tools/verify_class_vocabulary.py— written before the amendment, and the thing that keeps this defect closed. Run it after any edit to this file or to the machine twin. ⚠ Scope-corrected 2026-07-15-C — see §3.2. "This file or the machine twin" was the whole of the verifier's scope, and it was too narrow: it never opened the 23 chapters, and reported 0 while 52 chapter rows still carried the old strings. The sentence stands as written because it is the evidence of how the gap read from inside. The verifier now scans the chapters too, and prints its own scope before any result.What is NOT closed by this. Two lines, not one.
- The 22 untraced rows. The rows are correctly labelled; 22 of them are not repaired.
NOT-SOURCED(20) ·NOT-CONFIRMED(1) ·NOT-LOCATED(1) still carry values this corpus could not trace to a primary. Each has a falsifier that would close it. Naming a defect precisely is not fixing it, and this ledger does not get to claim otherwise.- The 52 chapter rows this closure did not reach — see §3.2. This amendment closed this ledger and K20. It did not touch the chapters this file extracts: 52 rows across 10 of the 23 chapters carried the PRE-amendment class strings until AMENDMENT 2026-07-15-C. For one day this ledger disagreed with its own sources in the one column the amendment existed to fix, and §2's "carry as written" rule was therefore untrue of the class column — the ledger was ahead of the chapters, not a transcript of them. The chapters are now re-classed in lockstep and the two agree row-for-row; the gap is recorded rather than smoothed because a reader comparing this file to a chapter on 2026-07-15 would have found a difference this file never disclosed.
3.1 The defect as originally recorded (preserved verbatim — do not edit)
The text below is the section as written before the 2026-07-15 closure. It is the record of what was believed and what was found, and it stands.
Surfaced, not patched. NA-00 declares "six classes and only six". The chapters do not all obey it. Extracting every row shows the wing in fact uses additional class strings —
OBSERVED(bare: measured but not independently replicated),NOT-SOURCED,NOT-CONFIRMED,NOT-LOCATED,NEGATIVE,MODELED-CONTESTED,HONEST-class,NONDUM FALSIFICABILIS, and one row (NA-03's SI defining constants) deliberately carrying no class at all.This is the wing's own finding, not this ledger's editorialising. CN-06 and CN-07 both record it explicitly, and CN-07 states the reason precisely: a result that is soundly measured, genuinely uncontested, and simply never independently replicated fits none of the six — "OBSERVED-REPLICATED asserts a replication that did not happen, and OBSERVED-CONTESTED asserts a dispute that does not exist. Both are false, in opposite directions." Both chapters flagged the fix as belonging at the ledger — and both noted that this file did not exist at the time, which is why the gap stayed open.
This ledger carries the classes exactly as written and counts them honestly in both vocabularies (§5). It does not mint a seventh class — that is NA-00's decision, not this file's. Falsifier / closure: register an explicit
OBSERVED-SINGLE/OBSERVED-UNREPLICATEDvalue (andNOT-SOURCED) in NA-00, then re-class the flagged rows to it.
3.2 SCOPE CORRECTION — AMENDMENT 2026-07-15-C — the closure above was narrower than it read
The vocabulary amendment is not withdrawn. Twelve classes stand; no row's evidentiary standing moves; every count in §5 is unchanged. What was wrong is the scope of the closure, and the fact that neither this file nor its verifier said what the scope was.
The real number: 52. §3 records that 47 rows in this file were re-classed. It does not record that the chapters those rows were extracted from were not re-classed at all. The chapter-side residue was:
What the chapter cells still said Rows Re-classed to bare / qualified OBSERVED42 OBSERVED-SINGLENEGATIVE— the UNI ledger state, in a NATURA class column3 SUPERSEDEDas above— a pointer, not a class (NA10-31…NA10-35)5 OBSERVED-REPLICATED (adopted constant), resolved from the literal cell ofNA10-30, the row it points atcells not leading with a token ( CN05-06,CN05-31)2 the re-ordered cells §3 already names 52 42 + 3 + 2 = 47 — exactly the 47 re-classes §3 reports on this side. The chapters were the other half of the same edit, and only one half was made. The 5
as abovecells never appear in §3's count because extraction had already resolved them into an explicit class; they were a chapter-only residue, invisible from this file.The lane-crossing the reader could see (the 3
NEGATIVEcells). §3's deviation note explains at length whyNEGATIVEwas not registered into this vocabulary — it is a UNI ledger state and registering it here would put one token in both sovereign vocabularies. That reasoning was applied to this ledger and not to the chapters, soCN-01andCN-04went on printing**NEGATIVE (withdrawn)**and**NEGATIVE**in the Class column of a NATURA numbers table — where the reader renders them under a NATURA sigil. The cardinal rule was argued correctly in the ledger and violated in the chapters for a day. NowSUPERSEDED, mirroring this file.Nothing but the class token moved. Each chapter cell was mirrored from this ledger's class — never invented — and the chapters' own qualifier text was kept verbatim rather than overwritten with this file's shorter restatement of it (this ledger abbreviates; e.g.
CN07-05's cell here drops the chapter's verbatim Gordon & Hölldobler quotation and its4.2 / ln 2 = 6.06check). Value, units, scope, source and falsifier were asserted unchanged per row, per column, and the fiveas abovecells still readas abovein their Source and Falsifier columns, because only the Class column was in scope.How it is kept closed. The verifier now carries CHAPTERS as a scope of its own, counted on its own line, alongside the ledger and K20 — and prints every scope it covers before it prints any result, so this gap cannot hide again. It also checks that each chapter's table still aligns row-for-row with §4, making ledger/chapter divergence a finding rather than a silence. Proven able to fail by three positive controls (a re-injected bare
OBSERVED; a re-injectedNEGATIVE; a deleted table row) — each caught, each exit 1. Post-fix: 0 in every scope, exit 0, and the chapters' class counts equal this file's exactly (918 = 919 −NA03-16, the one row that lives in NA-03's prose — §2's disclosed918 + 1 = 919, arriving from the other direction).50 or 52? Both — and the difference is the instrument, not the corpus. The audit that found this reported 50 rows across 9 files; this correction re-classed 52 across 10. The gap is fully accounted rather than split: 50 is the count
reader/build.pyemits as build notes, and itsextract_natura_classes()accepts a registered class found anywhere in a cell; 52 is the leading-token count this file's §5 and its verifier use. Reconciled exactly:
52 − 5 + 3 = 50
- −5 the reader misses, each naming a class somewhere but not first:
CN05-06andCN05-31(already named in §3),CN06-30("…the latency; MODELED — its identification with T"), andCN08-05/CN08-24, whose qualifiers read "downgraded from OBSERVED-REPLICATED" — the cell cites the very class it was demoted from, and a substring rule reads that as the class. This is not a reader bug:extract_natura_classes()feeds a badge and says in its own docstring that it never invents a class. It is the right rule for rendering and the wrong rule for counting.- +3 the reader adds that are not defects:
CN04-22,CN11-59,CN12-41— the deliberately unclassed rows of §1. The reader has no exemption list, so it reports them every build; they are the 3 notes that remain on the colophon after this fix, and they are correct.Two instruments, two answers, one corpus. A count is not a fact until the rule that produced it is named — the same lesson §3 already recorded when 846 and 847 differed under two rules. The 52 stands, because a class cell must lead with its class: a row whose class has to be inferred from its qualifier is precisely the ambiguity that made
CN05-31need re-ordering.Standing, without flattery. This raises nothing and discharges no gate. It closes a scope gap that should not have shipped, found by an outside audit and not by this file. The number went up when the instrument was pointed at the right files, and was named when two instruments disagreed.

5. Counts by class
Total rows: 919, across 23 chapters (NA-00…NA-10, CN-01…CN-12).
Counted 2026-07-15, post-amendment, by ../tools/verify_class_vocabulary.py.
Every number below is machine-counted from the rows in §4, not asserted. Re-run the verifier and it
must reproduce them exactly; if it does not, this section is wrong and the rows win.
5.1 By class (all twelve registered classes)
Rows are counted at their leading class token (the compound-row convention, §1).

Reconciliation — 578 + 257 + 80 + 4 = 919.
5.2 Out-of-vocabulary rows — 0 of 919

This section previously carried a table of 72 out-of-vocabulary rows (the defect, §3). Where those 72 went, in full:
| Was written as | Rows | Now |
|---|---|---|
| OBSERVED (bare / unreplicated) | 42 | re-classed → OBSERVED-SINGLE |
| NOT-SOURCED | 20 | registered as-is → NOT-SOURCED (1 cell re-ordered to lead with the token) |
| NEGATIVE | 3 | re-classed → SUPERSEDED (the token NEGATIVE is UNI-side; §3) |
| MODELED-CONTESTED | 1 | registered as-is |
| NOT-CONFIRMED | 1 | registered as-is |
| NOT-LOCATED | 1 | registered as-is |
| HONEST-class | 1 | not a NATURA class — CN11-59, an HONEST signal, never calibrated |
| NONDUM FALSIFICABILIS | 1 | not a class — CN12-41, a register status, extra Arborem |
| no class carried | 1 | deliberately unclassed — CN04-22, a prediction, not a measurement |
| no evidence class (definitional convention) | 1 | deliberately unclassed — NA03-16, definitional |
| — total — | 72 | 68 registered + 4 deliberately unclassed |
The arithmetic that shows nothing was invented: the six canonical classes totalled 847 as published at §5.1 before the amendment, and total 847 after. Every re-class relabelled a row that was already outside the six, to the class that was always true of it. Not one row changed evidentiary standing; not one row left the six. No value, source, or falsifier changed in any row — machine-checked across all 919 rows and all 10 columns.
The one counting subtlety, disclosed. Under a strict leading-token count the old text yields 846, not 847. The single difference is
CN05-31, whose class cell read "rung MODELED; overall band OBSERVED-REPLICATED" — a compound that does not begin with a class token and so does not parse mechanically. The published §5.1 counted it at MODELED anyway (its 251 included it), which is why the published subtotal was 847. The amendment re-ordered the cell to "MODELED (the ladder rung); OBSERVED-REPLICATED (the overall band)" so that it parses as what it was always counted as. Value, source, falsifier and evidentiary standing are untouched; only word order moved. This is printed because a subtotal that looks stable at 847 under one rule and moves 846→847 under another must have the difference named — otherwise the stability is an illusion the reader has no way to audit, and this ledger would be asserting its own correctness rather than showing it.

6. Standing fences carried from the wing
- RES IPSAE, NON SIMULACRA. Every value carries a real citation, or it is written
NOT-MEASURED. There is no third state. A plausible-sounding number with no source is the worst defect available in this wing. - Every numeric claim carries value + units + scope + class + source + falsifier. A number without units or scope is a defect. A rate without its condition is not a number.
- SIGNUM SIGNUM MANET. The measured value and the commentary about it travel separately.
- TRUE vs HONEST stay sovereign. A chakra-frequency table is INADMISSIBLE as physics and may
be recorded as an HONEST/cultural signal — never as a TRUE/measured one, and never converted.
CN-11's
first-person testimonyrow is the wing's only HONEST-class row and is never calibrated. - Nature as authority, stated precisely: nature is the authority because it has already run the experiment — a long parallel search under real physical constraints in which the failures were deleted. Convergence is evidence of a constraint-optimum.
- The mandatory counterweight, travelling with it everywhere: Gould & Lewontin (1979), Proc. R. Soc. Lond. B 205(1161):581–598 — not every trait is an adaptation. Therefore "nature does it this way" is a hypothesis generator, never a proof, and a biomimetic design must still beat a tuned conventional baseline on a pre-registered metric (rule M7) or be recorded NEGATIVE.
- QUAESTIO-APERTA. "Full human" and "beyond human" are permanent open questions — never a target, never a milestone, never a deliverable. See CN-12 and §7 of the machine twin.
7. Machine-readable twin
../gpt/knowledge/K20-constants-ratios-and-nature-ledger.json
carries the categorised view of this ledger — constants, dimensionless numbers, scaling laws,
frequencies, inadmissible claims, and open questions — with every entry tracing to its chapter.
Both files are generated from one extraction pass and cannot disagree.
Every row is falsifiable at its own row. Any row whose cited source does not contain its value is a defect: report it and the row is corrected or demoted to NOT-MEASURED.
sha256 e3f567a5d7005ff8 — of the original file, so what was ingested stays checkable.
Plain — written for this website, not the source document
Nature's numbers are gathered here, and not one of them is a gate. The file says so before it says anything else: reading a published result about the natural world raises no rung on the program's own ladder. This ledger is a list rows are added to and never edited, and it contributes no evidence to what the program has built. The two records are linked by audited reference, never merged. The program's own position is untouched by every row below — a developmental simulation, a toy world, never a person.
The rest is extraction. Every numbered row from the wing's chapter tables is carried whole, with its value, units, scope, evidence class, source, and the result that would show it wrong. Values are copied as written. Ranges and live disputes stay whole and are never averaged. A row that could not be traced says exactly how it failed, because an absence in the literature and a gap in this corpus's own homework are different facts.

Clear — written for this website, not the source document
Every numeric row from the nature wing's chapters is gathered into one place, so that wing has a ledger of its own, a list added to and never edited, the way the program does. This is borrowed science: other people measured it and published it, and it is quoted here. It contributes no evidence to the program's own build, which is a simulation — a toy world, not a person. The gathering is extraction only: no row was added that no chapter contains, and no value was invented, improved, averaged or completed.
Its first section is about sovereignty, and it is the reason the file exists. One ledger describes nature's regularities as measured by other people in published work. The other describes the program's own build status. They use different vocabularies and are cross-referenced only by explicit link, never merged. The cardinal rule is that a citation about nature is never a gate for the program, and no row here raises, lowers or discharges a row there.
The second section defines the classes. There are twelve, in three groups. The measured group says how much independent corroboration exists: replicated, single, or genuinely contested. The derived group says the assumptions are the limit: modelled, modelled and disputed, or hypothesised. The last group carries no usable value and says precisely why not: inadmissible as stated, superseded by its own field, never measured, not traced to a source, named but unread, or searched for and not found. Those last four are deliberately kept apart, because an absence in the literature is a fact about the world and an untraced value is a fact about this corpus.
A further section records a defect openly. The vocabulary originally had six classes, and the file's own rows refuted that, because a number of them could not be placed. The amendment that widened it is carried with the original wording struck rather than deleted, along with a later correction showing that the first amendment's scope was narrower than its record read.
The bulk of the file is then the rows themselves, chapter by chapter, followed by counts by class, the standing limits carried from the wing, and a pointer to a machine-readable twin generated from the same pass.
