Elamur Groupantsmova-terminal-main
The groupant beside tools/terminal/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 | Forward approximant |
| ast | partial | syntax.json |
| composition | partial | Composition |
| cost | partial | Cost |
| descriptant | present | Descriptant |
| invariant | partial | Invariant |
| tests | finite 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.
| id | type | label | where |
|---|---|---|---|
behavior_complement | behavior_complement | partial source derived model | behavior_complement |
reverse_reconstruction | reverse_reconstruction | partial source derived model | reverse_reconstruction |

mova-terminal-main
Descriptant
mova-terminal CLI: status PROFILE, ask PROFILE [--wait] (question on stdin), answer PROFILE ID, abandon PROFILE ID REASON. Source: tools/terminal/src/main.rs.
Forward approximant
Load and validate the profile from the second argument; match exact argument shapes; ask reads at most question_max_bytes + 1 bytes of stdin (so an oversized question is refused by the library) and calls ask or ask_wait (500 ms poll); every command prints one JSON line on success; any error prints mova-terminal: ERROR to stderr and exits 1.
Invariant
Unknown commands, extra or missing arguments, or an invalid profile have no effect on the terminal or journal beyond the error message and a non-zero exit.
Cost
O(1) dispatch plus profile load (at most 64 KiB) plus the chosen library operation.
Composition
Executable over lib.rs.
behavior_complement
No flags besides --wait, no daemon mode, no queue, no retry, no reading of a question from arguments. Counterexample: mova-terminal ask PROFILE --now prints the usage and exits 1. Evidence status: source-derived model, not covered by an end-to-end CLI test.
reverse_reconstruction
The printed JSON names the id, answer path or answer; the question is not printed and is recoverable only from the task file under the profile root. No unique inverse is claimed.
tests
Checks
No dedicated CLI test: the binary is built by cargo test --manifest-path tools/terminal/Cargo.toml --release --locked (two identical runs on 2026-11-04) and was used for the live runs of 2026-11-04 (one question each to Sol and Opus). Argument-shape errors are a source-derived claim only.
