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.

실패의 종류가 바뀌면 운영자가 읽을 정보가 사라진다

ProtobufMessageContract javadoc이 두 결함을 보존한다. 두 번째가 특히 이 저장소의 반복 주제다 — 실패의 종류가 바뀌면 운영자가 읽을 정보가 사라진다.

관계

  • 검증되지 않는 스키마 파일은 문서임을 파일 안에 적는다 같은 분석 리프에서 끌어낸 규칙이다.
  • 신뢰할 수 없는 입력 쪽 경계를 먼저 테스트한다 같은 분석 리프에서 끌어낸 규칙이다.

본문

ProtobufMessageContract javadoc이 두 결함을 보존한다. 두 번째가 특히 이 저장소의 반복 주제다 — 실패의 종류가 바뀌면 운영자가 읽을 정보가 사라진다. messaging-core-apiFailureDescriptor 설계, MessageContractKey의 2단 에러, JSON codec의 unwrapTooLarge가 전부 같은 관심사다.

proto 파일의 주석이 남긴 규칙 셋

"Field numbers are the contract, not the field names ... Tags are never reused, and removed fields are reserved so that a later edit cannot take the number back." 이 규칙 셋 중 둘(개명 안전, 태그 재사용 위험)이 테스트로 증명되고 하나(reserved)는 증명되지 않는다.
