Elamur Groupantsworld-worldbook
The groupant beside world/src/worldbook.rs in the Mova repository: what the code computes, what it never does, how to go back from its outputs, its invariants, cost and checks.
Facts
Implementation material. A Mova code model describes this code at one source revision: partial models, finite checks and their stated scope. It is not a reviewed general exposition, and its labels are shown as written, never raised.
Components

Obernants
The typed relations around the forward model: the behaviour complement (what the code never does), the reverse reconstruction (every input compatible with an output) and specialised views.

world-worldbook
build_all parses topic sentences, merges key=(lower subject,predicate,lower text), first attrs plus unique(sourcekey,sentence) cites. principles groups triples of first8 sorted lemmas, >=min distinct first-cite keys and>=2source kinds, clean whole6..35word representative,<=8cites. write ranks support/cites/text and caps notes3/full1/mini. brain_body counts every cited pre-Sources line but emits first12/part. Compression learned depth decisions plus one index-order function-word restoration pass.
Modeling epoch 2026-10-31
Prospective source/branch/cost hypotheses were saved externally before source edits. This partial source-derived model retains observed boundaries rather than claiming complete verification. Compression/outcome/brain/standalone/list/writer/mini helpers tested; build/principles/teacher/gather/site/passenger read chains unexecuted. No surrogate.
approximant
Forward relation
build_all parses topic sentences, merges key=(lower subject,predicate,lower text), first attrs plus unique(sourcekey,sentence) cites. principles groups triples of first8 sorted lemmas, >=min distinct first-cite keys and>=2source kinds, clean whole6..35word representative,<=8cites. write ranks support/cites/text and caps notes3/full1/mini. brain_body counts every cited pre-Sources line but emits first12/part. Compression learned depth decisions plus one index-order function-word restoration pass.
Domain: Synthetic words/Markdown/list/tempfile outputs only; no corpus/parser/model/teacher/manual/site/full-school execution.
No executable percent surrogate: these categorical/effect observations lack a useful approximation metric. Future supported caps1/2/5/10% need a defined domain/metric and real reference evidence; no error or speed bound is claimed.
invariant
Merge order restored by source index after threads;1-based citations/heads, byte-length returns and kb*1024 budget. Valid tree heads required, depth boundedL even cycles. Root kept but one-pass function restoration not fixed point. Topic base first-byte capitalization needs nonempty ASCII-leading text.
Cost component: cost.md.
cost
Multiple full source scans and frequency maps, delegated parse, up toO(L^2) tree traversals,<=56lemma triples/fact, group/rank sorting and complete Markdown output. Writer compares freshly built citation sets; unchecked counters/budget arithmetic, no timing claim.
composition
family gather principles(min5)->write->brain_body, count can exceed retained lines. know perception counts unique known gap sources. tabular decisions overridden by grammar; teacher/model files outside tested paths.
models
behavior_complement
Shared lemma triples not entailment or independent-source proof. Merge uses text not object. writer pd=false excludes quote; parsed pd flag broadly includes CC BY prefixes, no legal guarantee. mini floor5/main floor10 may exceed byte budgets. Empty compression '.', stands_alone empty true; malformed heads/topic slicing can panic.
reverse_reconstruction
Compressed output admits deleted subtrees and many decision lists/parses. Markdown loses fact attrs/lemmas/extra cites. Brain body admits arbitrary omitted13th+ lines with same count and sections after Sources. Principle representative admits many shared-lemma support sets.
world_worldbook_invariants
Merge order restored by source index after threads;1-based citations/heads, byte-length returns and kb*1024 budget. Valid tree heads required, depth boundedL even cycles. Root kept but one-pass function restoration not fixed point. Topic base first-byte capitalization needs nonempty ASCII-leading text.

world_worldbook_representation_join

15 selected cases passed twice debug and twice release with identical sorted names/outcomes, exits0. control-worldbook: compiled source mutation failed with exit101; source restored byte-for-byte and15positive tests passed. No live teacher, corpus, state activation, GPU, or full-school run. Temporary synthetic files use unique process-id paths and are removed after passing tests.

Strict whole-crate Clippy was not repeated merely to reproduce existing dependency/source lints; Cargo warnings retained in receipts.
