DongHyeonkaandClaude Opus 5 b2963105a8 docs(keycloak-session-store): import the session-storage lab as a new project
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.

# 인가 실패와 프로그래밍 오류를 예외 타입으로 가른다
거절은 전부 `MessageAuthorizationException` 또는 `MessagingConfigurationException`이고 안정 코드가 붙는다. `IllegalArgumentException`은 구조적으로 불가능한 값에만 쓴다.

거절은 전부 `MessageAuthorizationException` 또는 `MessagingConfigurationException` 이고, 코드가 붙어 있다. 메시지가 전부 "무엇이 왜 거절되었는가" 를 서술형으로 쓴다.

## MessageAuthorizationException 참조 위치

## IllegalArgumentException을 쓰는 자리
`IllegalArgumentException` 은 **구조적으로 불가능한 값**에만 쓴다 — 음수 카운터, 빈 문자열, 역전된 윈도우, 4-eyes 위반. 인가 실패와 프로그래밍 오류가 예외 타입으로 갈린다.
## 로그 위생이 예외마다 같지 않다
`toString()` 하나가 로그 위생을 명시적으로 다룬다. `ApprovalGrant` 는 record 라 기본 `toString()` 이 전 필드를 찍는다는 점은 대비된다 — 다만 `ApprovalGrant` 자체가 로그에 닿는 경로는 확인되지 않았다.
