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.

서수 컬럼은 값이 끼어들면 모든 행을 조용히 바꾼다

IN_PROGRESS에서만 전이할 수 있고 커밋은 결과 참조가 비면 거부한다. 상태 컬럼은 EnumType.STRING이다.

본문

IN_PROGRESS 에서만 전이할 수 있다(requireInProgress). 커밋은 결과 참조가 비면 거부한다.

원장의 전이

상태 컬럼을 문자열로 두는 이유

EnumType.STRING 을 쓰는 이유가 javadoc 에 있다 — 서수 컬럼은 열거형에 값이 끼어들면 저장된 모든 행을 조용히 다른 값으로 만든다.
