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.

# 로그 마스킹은 PII 차단 보장을 복구하지 않는다

`app-bootstrap`의 `LogMaskingPatterns`는 방어 심층화로 몇 가지 secret 형태를 mask하지만 arbitrary email address나 free-form body PII를 일반적으로 제거하는 규칙은 없다.

`app-bootstrap`의 `LogMaskingPatterns`는 방어 심층화로 다음과 같은 secret 형태를 mask한다.
|
|
|
|
- password/secret/token/api-key 계열 key=value
|
|
- Authorization credentials
|
|
- standalone Bearer token

## 마스킹 규칙이 덮지 않는 것
|
|
|
|
arbitrary email address나 free-form body PII를 일반적으로 제거하는 규칙은 없다. app-bootstrap README 자체도 regex masking을 **보증이 아니라 defence-in-depth**라고 설명한다. 따라서 현재 "logger signature 때문에 PII가 들어올 수 없다"는 1차 방어선 설명은 사실과 맞지 않는다.
