Elamur Groupantsgparse-model-configuration
The groupant beside gparse/src/model.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 |
| cost | symbolic source derived | invariant |
| descriptant | present | descriptant |
| invariant | partial | invariant |
| tests | partial 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.

Source-bound description
GELU chooses erf/tanh; config serialization records fields, parse starts default and processes ordered key=value lines.
Epoch 2026-10-31
Prospective model was recorded before edits. Added tests use bounded synthetic fixtures; production algorithms unchanged. Coverage is partial, not proof. No trained corpus, live teacher or throughput experiment was executed.
approximant
Forward approximant
GELU chooses erf/tanh; config serialization records fields, parse starts default and processes ordered key=value lines.
Domain: valid source-specific dimensions and resources stated in invariant; no automatic production substitution. Numerical observations are finite checks, not an end-to-end relative bound. Executable Rust surrogate: unsupported gap; existing exact tests are not surrogates. Future metric-specific caps may be 1/2/5/10%, never above 10%.
invariant
Invariant and cost
Bad numerics retain current field; unknown GELU errors; duplicate valid fields last win.
Cost
O(config bytes), constant field state.
Allocation, finite arithmetic, platform dimensions and external failures are not universally certified.
models
Typed model catalog
behavior_complement
Unsupported saved GELU cannot be repaired by later line because parsing aborts.
reverse_reconstruction
Many unknown-key/invalid-number texts map to the same cfg; saved form is canonical but not source-text inverse.
numeric_failure
parse failure retains current field, so invalid later repeated number keeps earlier successful value.
text_projection
Unknown keys and lines without '=' ignored; whitespace not trimmed.
activation_choice
Erf calls gelu_erf, Tanh calls gelu.
roundtrip_domain
Finite ordinary numeric fields serialize and parse; config does not enforce heads/divisibility/dropout validity.
tests
Checks and limits
Selected parent checks relevant to this fragment (not exhaustive): model::tests::embeddings_get_gradients; model::fused::which_ops_backprop; activation_configuration_roundtrips; CUDA gradient/GELU/synthetic optimizer checks; CPU prediction
Selected commands run twice debug and twice release; exact receipts and source-to-test mapping retained in wave30 gparse external run directory. Tests do not certify allocation failure, all NaN/overflow inputs, trained-model accuracy or corpus timing. Compiled mutants cover selected boundaries; per-source coverage is recorded in the external map, not presumed.
