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.

=== Q4 ① 다중 값 role — 구분자와 동명 헤더 ===
|
|
(a) 쉼표 구분 한 개 헤더
|
|
보냄: X-Auth-Request-Roles: admin,editor,viewer
|
|
도착: ['admin,editor,viewer'] ← 문자열 하나 그대로
|
|
|
|
(b) 동명 헤더 두 개
|
|
보냄: X-Auth-Request-Roles: admin
|
|
X-Auth-Request-Roles: editor
|
|
도착: ['admin', 'editor'] ← ★ 둘 다 도착. 덮어쓰지도 합치지도 않는다
|
|
|
|
(c) 값 안에 구분자가 들어간 경우
|
|
보냄: X-Auth-Request-Roles: role-with,comma
|
|
도착: ['role-with,comma'] ← (a) 와 구별 불가
|
|
|
|
=== Q4 ② 헤더 크기 상한 ===
|
|
보낸 길이 1000 → HTTP 200, 도착 길이 1000
|
|
보낸 길이 4000 → HTTP 200, 도착 길이 4000
|
|
보낸 길이 8000 → HTTP 400 (Tomcat 의 HTML 오류 페이지)
|
|
보낸 길이 16000 → HTTP 000 (응답을 못 받음 = 연결이 끊김)
|
|
보낸 길이 32000 → HTTP 000
|
|
|
|
→ 자르지 않는다. 거부한다. 그리고 거부하는 계층이 둘이며 증상이 다르다.
|
|
|
|
=== Q4 ④ upstream 이 검증하는가 ===
|
|
아무 인증 없이 보냄:
|
|
x-auth-request-user ['administrator']
|
|
x-auth-request-email ['admin@example.com']
|
|
x-auth-request-roles ['realm-admin,superuser']
|
|
remoteAddr 100.123.124.30
|
|
→ 그대로 도착. 검증 없음.
