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.

새 레코드를 추가하면 컴파일이 codec 갱신을 강제한다

ObjectControlRecord가 sealed이고 codec이 exhaustive switch를 쓰므로 계열이 닫혀 있고, 모르는 스키마는 덮어쓰지 않고 격리된다.

본문

ObjectControlRecord는 열한 개 구현만 허용하는 sealed interface이고, javadoc이 규칙을 적는다 — "Unknown families and schemas fail closed." codec의 payload(...)가 그 계열에 대해 exhaustive switch를 쓰므로, 새 레코드를 추가하면 컴파일이 강제로 codec을 갱신하게 만든다.

ObjectControlRecord 참조 위치

:::evidence key="adapter-outbound-objectstorage-c04" alt="코드베이스에서 ObjectControlRecord 를 검색한 출력 35줄. 이 기록이 세는 참조가 그 출력에 그대로 보인다." caption="ObjectControlRecord 코드베이스 검색 — 35줄 · exit 0" zoom="true" :::

모르는 스키마는 덮어쓰지 않고 격리한다

스키마 버전은 ControlRecordSupport.headerschemaVersion != 1을 거부한다 — "only control schema version 1 is writable". 더 새로운 스키마를 만나면 UnsupportedObjectControlSchemaException으로 격리한다("A newer or unknown durable schema that must be quarantined rather than overwritten").

누출 금지가 가시성으로 성립한다

objectstorage.control 패키지를 leaf 밖에서 참조하는 코드는 0이다(151-... §8.1, exit=1). CLAUDE.md의 "control-record types leaking into application-core" 금지가 가시성으로 성립한다.
