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.

# 만료 직후 takeover 전 창은 보이지만 계약이 그것을 금지하지 않는다

cleanup settlement query는 claim token을 fence하고 reaper takeover가 token을 교체한다. lease expiry 직후 아직 takeover 전인 worker가 settle할 수 있는 window는 보인다.

cleanup settlement query는 claim token을 fence하고 reaper takeover가 token을 교체한다. lease expiry 직후 아직 takeover 전인 worker가 settle할 수 있는 window는 보이지만, 새 owner가 생긴 뒤 stale worker가 상태를 덮어쓰는 race는 token CAS가 막는다.

## finding으로 올리지 않은 이유
|
|
|
|
durable-operation과 달리 현재 계약만으로 "expiry 순간부터 절대 settle 금지"라고 확정할 충분한 근거가 없다.
