Elamur Groupantsmath-solver-cli-local-calculation
The groupant beside math/src/bin/mathsolve.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 |
| descriptant | present | descriptant |
| invariant | partial | invariant |
| tests | partial bounded evidence | 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.

Model text
descriptant
Source-bound description
Plan reads JSON file, extracts plans, executes default Expect20s and prints gate/traces; parse errors printed. Calc each argument parse/eval20s, prints substeps/independent check/exact answer.
Epoch 2026-10-31: prospective model before bounded synthetic tests; production behavior unchanged. Source scope bytes[74238,75765). Large effect branches source-modeled only; controls command avoided because potentially expensive Fermat expression. Not every branch in this fragment executed.
approximant
Forward relation
Plan reads JSON file, extracts plans, executes default Expect20s and prints gate/traces; parse errors printed. Calc each argument parse/eval20s, prints substeps/independent check/exact answer.
Domain: Synthetic bounded2+3*4 CLI smoke; run directory already created outside scope.
Executable Rust approximant unsupported: categorical/effect observations have no useful percentage metric yet. Future caps1/2/5/10% only; no automatic substitution.
invariant
Invariant and cost
These branches contain no teacher invocation. Plan gate failure printed does not necessarily produce CLI nonzero exit; calc errors propagate Result.
Ordering: Plan read→parse→run→print; calc parse→eval→subs→independent→answer.
Cost: Input bytes+delegated exact engine+trace output, per-plan/expression20s cooperative limits.
composition
Composition and epoch memory
plan/Trace and calc/Env source code provide semantics; CLI formatting not a new arithmetic oracle.
Source scope bytes[74238,75765). Large effect branches source-modeled only; controls command avoided because potentially expensive Fermat expression. Not every branch in this fragment executed.
Partial syntax and finite tests do not establish all caller assumptions.
models
behavior_complement
These branches contain no teacher invocation. Plan gate failure printed does not necessarily produce CLI nonzero exit; calc errors propagate Result.
reverse_reconstruction
Calc14 admits 2+3*4 and many expressions; printed verification loses plan metadata and serialized form.
failure_precedence
Plan read→parse→run→print; calc parse→eval→subs→independent→answer.
representation_transport
plan/Trace and calc/Env source code provide semantics; CLI formatting not a new arithmetic oracle.
resource_boundary
Input bytes+delegated exact engine+trace output, per-plan/expression20s cooperative limits.
domain_boundary
Synthetic bounded2+3*4 CLI smoke; run directory already created outside scope.
tests
Evidence, 2026-10-31
Selected actual-source checks: cargo test -p math --bin mathsolve wave28; isolated calc smoke. Exact commands, numeric statuses, normalized outcomes, compiled assertion controls and restoration receipts are in the external wave28 mathcontrol run.
Source scope bytes[74238,75765). Large effect branches source-modeled only; controls command avoided because potentially expensive Fermat expression. Not every branch in this fragment executed.
No live teacher/API, trained model, corpus/held-out, GPU, DB or expensive benchmark run. Parent syntax generated twice identically. Scope remains partial.
