Elamur Groupantskg-main-parse-lines
The groupant beside kg/src/main.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 |
first_tab | first_tab | partial source derived model | first_tab |
read_failure | read_failure | partial source derived model | read_failure |
status_projection | status_projection | partial source derived model | status_projection |

kg-main-parse-lines
Arbitrary TSV helper and synthetic Morph→parse→report composition.
Modeling epoch — 2026-10-31
Source read before tests and models; retained prospective notes accompany the parent. Current evidence uses bounded invented inputs only. This is partial modeling, not proof or corpus accuracy.
approximant
Forward relation
Read valid first-tab rows until line read failure, load names, collect normalized vocab, Morph::load, then create output and emit ok/members or reject reason.
Executable approximant gap
Exact categorical structure, identifiers, parser decisions and effects have no useful percentage metric established here. No executable surrogate, automatic substitution or 1/2/5/10% guarantee is claimed.
invariant
Invariant and domain
Output has one row per retained TSV row; malformed no-tab rows skipped; synthetic2-row fixture retains ids and question rejection.
Cost and resources
O(input bytes)+two dictionary passes+parse costs; all rows retained before output.
cost
Cost and resources
O(input bytes)+two dictionary passes+parse costs; all rows retained before output.
composition
Composition
Arbitrary TSV helper and synthetic Morph→parse→report composition.
Read valid first-tab rows until line read failure, load names, collect normalized vocab, Morph::load, then create output and emit ok/members or reject reason.
The parent invokes scoped transformations through the actual functions named in their source ranges. Children partition useful observations, not a complete semantic proof; boundaries can omit helpers, tests and effects.
models
behavior_complement
No output is created before input/names/Morph succeed. ok does not imply render_check; no grammar completeness validation here.
reverse_reconstruction
Output ignores malformed rows/read-error tail and original morphology alternatives; id and text retained for accepted rows.
first_tab
Text may contain additional tabs because split_once retains suffix.
read_failure
map_while(Result::ok) stops silently at first I/O error rather than propagating it.
status_projection
Reject::code collapses detailed unknown/conjunction words into category labels.
synthetic_scope
Actual tiny bz2 dictionary and names file are used; no stored graph is modified by this helper.
tests
Evidence
Parent source checks (a fragment inherits only the behavior they actually exercise):
- wave29::synthetic_reader_parse_and_sub_precedence
Selected kg tests: 15 named outcomes, twice debug/twice release, equal sorted outcomes. Standalone actual global/build.rs: 3 named outcomes per run, twice debug/twice optimized; build_child is normally no-op, parent fixture invokes it against isolated synthetic seeds. Eight compiled source mutations (one per source) each compiled successfully and exited101 on the focused assertion; exact source restoration followed by positive rerun.
This fragment's untested branches remain source-derived. No live graph, DB, corpus, teacher, GPU or held-out evaluation was used. Command specs and numeric exits are retained in the external wave29 graphlang receipt. Strict kg Clippy reports existing source lints; see receipt.
