# mova-serve-server

The groupant beside tools/mova-serve/src/server.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

- **kind:** groupant
- **status:** partial source bound model
- **source:** [`tools/mova-serve/src/server.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/mova-serve/src/server.rs)
- **repository folder:** [`tools/mova-serve/src/server.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/mova-serve/src/server.rs.groupant)

> **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](#approximant) |
| **Ast** | partial | `syntax.json` |
| **Cost** | symbolic source derived | [Cost](#cost) |
| **Descriptant** | present | [Descriptant](#descriptant) |
| **Invariant** | partial | [Invariant](#invariant) |
| **Tests** | executed bounded checks | [Tests](#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.

| relation | type | label | where |
|---|---|---|---|
| Behavior complement | behavior complement | partial source derived model | [Behavior complement](#behavior-complement) |
| Reverse reconstruction | reverse reconstruction | partial source derived model | [Reverse reconstruction](#reverse-reconstruction) |
| Model presence | model presence | partial source derived model | [Model presence](#model-presence) |

## Model text


### Descriptant

The service: routes (pages, short links, CoNLL-U, API, MCP, health, terms, account flow), the worker pool behind a
bounded queue, the cache, the quotas, the burst limits, identity by key or session, the request log, and the HTTP
glue.

### Approximant

`respond(req) = route(req) ∘ who(req)`; `parse_for = chars ≤ max ∧ quota.check ∧ bucket.take → answer
(cache | pool) → quota.charge`.

### Invariant

A full queue answers 503 at once; a timeout 504; every parse request is logged with its text and no address; quota
headers on every parse answer; the analysis bytes are the same for the same text.

### Cost

A cache hit ≈0.01–0.06 ms through the route (2026-11-06); a miss the engine's cost.

### Behavior complement

No TLS (the proxy's), no request timeouts on slow uploads beyond the body bound.

### Reverse reconstruction

The log recovers each request's text, endpoint, status, latency and cache outcome.

### Model presence

Accounts only with sign-in settings; short links only with a state directory.

### Tests

`server::tests`: the API schema and the cache's second answer, size limits and word quotas, the daily refusal
message, the burst limit, the busy queue with a one-worker control, MCP key and origin checks with a tool call
charged to the account, pages, links, terms and the log, the account flow's CSRF, terms and origin checks.
