Elamur Groupantsonto-describe-field-render
The groupant beside onto/src/describe.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
| component | label | where |
|---|---|---|
| approximant | partial | approximant |
| ast | partial | ../syntax.json |
| composition | partial | composition |
| cost | partial | cost |
| descriptant | present | descriptant |
| invariant | partial | invariant |
| tests | executed bounded checks | tests |
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.
| id | type | label | where |

behavior_complement | behavior_complement | partial source derived model | behavior_complement |
reverse_reconstruction | reverse_reconstruction | partial source derived model | reverse_reconstruction |

flag_counts | flag_counts | partial source derived model | flag_counts |

onto-describe-field-render
For lists choose core-known-nonempty then graph then n/a then unknown; numbers core only;13 flags
Epoch 2026-10-31
Specialized source fragment bytes [3331,9367); shared parent AST. Excludes unrelated parent operations and added test module.
approximant
Scoped forward
For lists choose core-known-nonempty then graph then n/a then unknown; numbers core only;13 flags
Domain
This byte-scoped operator uses the parent valid-state domain plus the following local restrictions:
Known empty list falls through; risks empty Known means none and filled
filled=Σapp&&known<=Σapp
First upward edge≤12, no full ancestor list
Known seed lines retain winning seed/layer/source snippet
No executable percentage surrogate established.
invariant
Local observations
Nonempty core excludes graph substitution; character-only seed excludes props filled
Known empty list falls through; risks empty Known means none and filled
filled=Σapp&&known<=Σapp
First upward edge≤12, no full ancestor list
Known seed lines retain winning seed/layer/source snippet
cost
Scoped cost
One resolve, one parts_of traversal, at most12 first-up steps, then17 Kb::prop calls. List graph rendering takes at most12 entries per relation after filtering; generated text and proof formatting memory depend on selected seeds/labels.
Symbolic accounting; no timing claim or whole-system speed bound.
composition
Parent join
field-render supplies the parent relation: For lists choose core-known-nonempty then graph then n/a then unknown; numbers core only;13 flags
Output compatibility is conditional on the local domain and earlier-branch exclusions. Other parent branches are outside this fragment.

behavior_complement
Nonempty core excludes graph substitution; character-only seed excludes props filled
reverse_reconstruction
Identical13 flags/text admit hidden graph edges past cap and nonselected core senses
list_branch
Known empty list falls through; risks empty Known means none and filled
flag_counts

Evidence
Parent tests.md identifies selected actual-code checks. Fragment is a source-scoped partial model; parent finite fixtures do not establish exhaustive branch coverage or every local equation.
