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.

### 17.4 P2 — 직렬 스트림 기록기의 가장 오래된 것 버리기가 잘못된 메시지의 바이트를 뺀다
|
|
|
|
```java
|
|
case DROP_OLDEST -> {
|
|
GrpcStreamEnvelope<T> dropped = queue.pollFirst();
|
|
if (dropped != null) {
|
|
queuedBytes = Math.max(0L, queuedBytes - nextBytes); // ← 들어오는 메시지의 크기
|
|
droppedMessages++;
|
|
}
|
|
enqueue(kind, payload, snapshotVersion, resumeToken, nextBytes);
|
|
yield GrpcStreamWriteResult.DROPPED;
|
|
}
|
|
```
|
|
|
|
버려지는 것은 꺼낸 봉투인데 빼는 값은 새 메시지의 크기다. 봉투는 크기를 성분으로 담지 않으므로 이 지점에서 버려지는 크기를 알 방법이 없다.
