The keycloak project ended with four open questions that design could not
settle. A two-VM lab was built to answer them by measurement, and this is
that material: 26 experiments, 125 raw command outputs, 22 browser captures.
Follows the import procedure in README.md.
source/ the originating repository verbatim — 78 documents, 28 SVGs,
8 manifests, plus .source-revision recording the commit
final/ the SSOT
document.md 729 lines written from the 29 experiment documents, not
concatenated: what was predicted, what was measured, and
where the measurement itself was wrong
evidence/raw 125 outputs, flattened to <experiment>__<file> because
the originals collided (01-baseline.txt appeared three
times) and the audit only globs the top level
evidence/meta one per raw file; command and exitCode are null and the
README says why rather than inventing them
evidence/browser 22 captures
assets/ three diagrams through techviz
.techviz/ their VizSpecs
A separate project rather than an addition to keycloak: the B-layer answers
that project's four questions, but the A, C and D layers are about cluster
failure, SSO and operations, and one document.md should hold one subject.
The four question records there can point here through 관계.
Recorded rather than papered over: only three of the 28 diagrams were
remade. The repository forbids hand-drawn SVG and forbids titles inside the
canvas; all 28 originals carry both, so converting them is redrawing, not
reformatting. They stay in source/ and the gap is written into the document.
verify-pipeline.py passes. audit-records.py reports no issues.

# Outbox에 행을 쓰는 진입점만 구현이 없다
|
|
|
|
세 실행 경로가 있고 그중 Outbox 쓰기의 진입점만 구현이 없다.
|
|
|

## 관계

|
|
- **계약만 담는 leaf도 계약의 거절 조건은 자기 레인에서 검증한다**
|
|
같은 분석 리프에서 끌어낸 규칙이다.
|
|
- **record의 `equals`를 좁히면 이유를 적는다**
|
|
같은 분석 리프에서 끌어낸 규칙이다.
|
|
- **호출 컨텍스트가 계약이면 그 컨텍스트를 검증할 수단을 함께 정한다**
|

같은 분석 리프에서 끌어낸 규칙이다.

## 본문
|
|
|
|
<!-- body:start -->
|
|
|
|
**Outbox 쓰기** — 애플리케이션 트랜잭션 안에서 `ReliableMessagePublisher.addToOutbox(...)` → `OutboxRepository.append(record)`. 이 진입점의 구현이 없다(§12.1).
|
|
|
|
**Outbox 릴레이** — `claimBatch(owner, size, lease, now, maxAttempts)` → `List<OutboxLease>` → 각 lease에 대해 발행 → 결과에 따라 `markPublished`/`markAmbiguous`/`markExhausted`/`markFailed`(lease 기반) → `APPLIED`면 정상, `STALE_LEASE`면 다른 릴레이가 가져감.
|
|
|
|
**Inbox** — `handleOnce(consumerName, delivery, action)` → 한 트랜잭션 안에서 `reserve(messageId, consumerId, now)` → true면 `action.apply(delivery)` → 커밋.
