# Procedures: corpus forms

Analysis of real fragments: package identifier, act name, the key fragment, form rating
(exemplary / debatable / wrong-form choice) and why. Corpus-wide count:
98 procedures in 69 packages, 468 transitions.

## Law

### 1. RK procurement — transitions on domain events (exemplary, inspected)

Package `kz.corpus.procurement` — Kazakh public procurement act (Kazakhstan):

```law
transition OpenBids {
    label ru-KZ official "Статья 6 пункт 1 подпункт 2). Вскрытие заявок на участие по объявленной государственной закупке";
    from Announced;
    to BidsOpened;
    on BidsOpeningHeld;
    when announced(lot);
}

transition Conclude {
    ...
    from BidsOpened;
    to Concluded;
    on ContractConcluded;
```

Exemplary: carriers are domain events (`BidsOpeningHeld`,
`ContractConcluded`), guards are empirics (`announced(lot)`); labels quote
the article. The form without `on` would be a loss here:
different transitions from one state on one synthetic step would give
`CARRIER_REUSED`, while domain events tell them apart by type.

### 2. Guard over a defeasible conclusion — legal (exemplary, page data)

`commission_required(lot)` in the procurement-rules package:
a guard reading an independent L1 group — it executes below the fold. Exemplary as the boundary of a "strong"
rule: rule strength alone does not fix the position relative to the fold;
the reading graph decides. A form reading a group above the fold is
already `LDC-E1348`.

## Sport

### 3. FIDE chess — synthetic steps (exemplary, inspected)

Package `fide.laws.chess` — FIDE Laws of Chess (international sport):

```law
assert "assert-a17": attempted_transition(entity_ref("urn:entity:fide:game"), StartPlay, GamePlayStep { id: "urn:entity:fide:game#step-0", time: @2023-05-02T09:00:00+05:00 }) {
    origin case_input;
}
...
evaluate truth(entered_state(entity_ref("urn:entity:fide:game"), Playing, GamePlayStep { id: "urn:entity:fide:game#step-0", time: @2023-05-02T09:00:00+05:00 }));
expect truth_status == TRUE_ONLY;
expect issues_within(info);
```

Exemplary: for transitions without `on` the carrier is a synthetic `GamePlayStep`
with intrinsic-only fields; the case presents steps with `id` and
`time`, the query reads `entered_state` with the same carrier. The
`issues_within(info)` expectation pins the document noise level. The same form —
in `research.procedure.chain` (`AccreditationStep`).

## Standard and customs

### 4. Most corpus procedures — transitions without `on` (exemplary, page data)

Several corpus procedures (thinning, chess, civil procedure): the carrier in
scenes is `<P>Step { id, time }`. Exemplary for procedures whose steps are
business steps, not domain events: synthetics do not invent world facts, they
date case steps. The reverse would be the mistake: declaring an event for
every step and forcing the case to invent facts that do not exist in the world
(two expert examinations by one decision would share one carrier).

### 5. Compound `parallel` with regions — only in conformance scenarios (form boundary)

`join all/any/quorum` and regions do not occur in the corpus; coverage is by conformance scenarios. Rating: not
a choice mistake but an unused form — parallelism with tokens
executes (concurrency in independent regions), but the corpus does not
use it. The teaching examples cover the linear case; a region with
`join` is a third-example candidate on extension.
