Elamur Groupantsmova-whale-terminal-adapter-tests
The groupant beside tools/whale/tests/terminal_adapter.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 |

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
End-to-end tests of the Whale's terminal adapter against a fake bash LLM in a real tmux server on a private socket: an answer, a usage-limit screen, and a full Whale run through its own terminal. Source: tools/whale/tests/terminal_adapter.rs.
Forward approximant
Start tmux -L <private socket> new-session running the fake script, set @mova_crab_owner, wait for TERMINAL READY, write a mova-terminal profile; MovaTerminal::ask -> answer file text; limit mode -> AskError::Limit within seconds, the next question refused as a replay; paper::run with MovaTerminal on a fixture paper -> one question answered, glossary from the answer, description without it.
Invariant
Never starts a model or uses the default tmux server; skipped without tmux (and without MOVA_OCTOPUS_TEST_MODEL for the Whale run); kills its private server on drop.
Cost
About 5 s (model load and tmux polling).
Composition
Parent: whale-workers; exercises terminal.rs, paper.rs, reader.rs and mova-terminal.
behavior_complement
Not covered: real Codex or Claude screens, folder-trust dialogs, real limit messages, concurrent Whales on one tmux server. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
Failures name the expected and actual AskError or the description and glossary; the temporary directory and tmux server are removed. No unique inverse is claimed.
Epoch 2026-11-04 (learning Whales)
Fourth test: the slow fake LLM writes its answer file, shows a working line for 1.5 s, then the idle marker; the adapter returns only after that and the next question is accepted.
Epoch 2026-11-04
Question literals carry the new items field (empty).
tests.md
Command: cargo test --manifest-path tools/whale/Cargo.toml --offline --locked with MOVA_OCTOPUS_TEST_MODEL=$MOVA_DATA/download/0/0.4/en.bin; tests/terminal_adapter.rs (3 tests: answer, usage limit, a full Whale run) against a fake bash LLM in a real tmux server on a private socket, tmux required, never a model (2026-11-04)
Negative control 2026-11-04: ignoring the limit text makes the limit test wait out the timeout and fail; restored afterwards. Finite fixtures; no live terminal; not a proof.
2026-11-04: 4 tests pass; negative control (adapter returns on the answer file alone) red, restored.
