Elamur Groupantsmova-topic-corpus-licence
The groupant beside tools/topic-corpus/src/licence.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 | Forward approximant |
| ast | partial | syntax.json |
| composition | partial | Composition |
| cost | partial | Cost |
| descriptant | present | Descriptant |
| invariant | partial | Invariant |
| tests | finite evidence | tests.md |
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 |
Model text
Descriptant
Licence classes (public domain, CC BY, SA, NC, ND, restricted, unknown), document origins (library, Sea Spider, consultant draft, our notes) and the public-admission rule. Source: tools/topic-corpus/src/licence.rs.
Forward approximant
classify(statement) by CC terms / PD / restricted words; public_admissible = origin Library and not local-only and class in {By, PublicDomain}.
Invariant
Sea Spider pages, consultant drafts and notes are never public-admissible, whatever licence they state (operator rule 2026-11-04).
Cost
O(length of the statement).
Composition
Parent: topic-corpus.
behavior_complement
No SA, NC, ND, restricted or unknown text is admitted for public use; no web origin at all. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
The class is a many-to-one image of the statement; the statement is not recoverable from the class. No unique inverse is claimed.
tests.md
licence::tests (classes of library statements; web and sol never public). Negative control 2026-11-04: dropping the origin condition turns licence and corpus tests red.
cargo test --manifest-path tools/topic-corpus/Cargo.toml --offline with WORLD_EN_MODEL=$MOVA_DATA/download/0/0.4/en.bin (18 unit tests; fixture library, fake papers binary, fake terminal, local Sea Spider store; two identical runs on 2026-11-04). Without the model the model-dependent tests report a skip.
Negative controls 2026-11-04 (each red, then restored): public admission without the origin condition; assert_public without the Sea Spider/draft/note refusals; seeding without the learner lock; shadow-library filter off; public citing that ignores refusals; cache eviction ignoring the hot pin.
These are finite fixtures and live samples; not a proof.
