Elamur Groupantsoctopus-animal-relay
The groupant beside tools/octopus/src/relay.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 |

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.

behavior_complement | behavior_complement | partial source derived model | behavior_complement |
reverse_reconstruction | reverse_reconstruction | partial source derived model | reverse_reconstruction |
Model text
model
octopus-animal-relay
Descriptant
Asking another animal in English: the deputy capability handler animal_ask relays the quoted English of a prompt to a configured animal socket and returns its English answer; ask_animal is the shared client for animals with a configured socket. Source: tools/octopus/src/relay.rs.
Forward approximant
validate: parameters exactly animal/socket/caller, socket absolute without /../, caller_name, one slot task kind text 1..1. execute: take socket and caller from parameters, the quoted task from the bound slot; ask_from(socket, id, run, task, normal, Some(caller), 30 s); ok -> {answer, request, request_id, failure, reply_sha256}; not ok or unreachable -> error.
Invariant
Stateless; trusted parameters animal, socket (absolute), caller; one text slot task; request id = invocation id.
Cost
One Unix-socket round trip bounded by 30 s plus the target animal answer cost.
Composition
Parent: native-octopus-deputy.
behavior_complement
never takes a socket from a prompt; never relays without a configured absolute socket; no retries; no urgency (normal priority); no authentication beyond the target allowlist and its 0700 directory. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
from the output one recovers the target, caller, request text and English answer; the target journal recovers the request by id. The full reply is kept only as its sha256. No unique inverse is claimed.
tests
Checks
cargo test --manifest-path tools/octopus/Cargo.toml --offline with MOVA_OCTOPUS_TEST_MODEL (22 unit tests incl. 4 socket, 2 relay; 2026-11-04) Negative control 2026-11-04: dropping the configured-socket checks in relay.rs turns configuration_requires_a_configured_socket red; restored afterwards. cargo test --manifest-path tools/seaspider/Cargo.toml --offline --locked with MOVA_OCTOPUS_TEST_MODEL=$MOVA_DATA/download/0/0.4/en.bin (34 unit + 9 end-to-end + 1 singleton CLI + 2 English tests; two identical runs on 2026-11-04) (served Crab-style animal_ask relay against a real Sea Spider) These are finite fixtures; not a proof.
