The audit found ~80 placeholders, and the damaging ones were where the
measuring apparatus itself was prose rather than a command:
a6 "( curl ... ) & 를 20개 띄우고 wait" — the 22.2s headline came from this
a3 "<로그인 반복, sid 를 /tmp/sids 에>" — the whole RPO measurement
a3 "<sid 목록>" — the control it is compared against
a5 "<수신 파드IP>" — the injection
a8 writes /tmp/tok, reads /tmp/rt — self-inconsistent, sent an empty token
b3 $KC / $RT / $NEW never assigned
c2 bare kcadm.sh with no kubectl exec
a1 conntrack tuples written by hand, though the direction flips per restart
Each is now a shell-expandable form: pod IPs from jsonpath, the admin password
from the secret, ids from kcadm --format csv, conntrack tuples derived from
"conntrack -L" with awk rather than transcribed.
Then the rewritten commands were executed against the live cluster, and one
of them failed — the 20-way load generator, written as "kubectl run --rm -i",
lost its output stream twice in a row. That is a trap this series already hit
once, and the rewrite reintroduced it. A-6 now uses a resident probe pod that
collects into a file and is cat-ed once; verified 20/20 lines.

An independent audit found ten documents printing values their evidence files do not contain. C-1 printed a session count of 0 where the evidence says 4, C-2 printed a success readback for a command that exited 1, and A-1 credited the conntrack flush with a split that the timestamps attribute to a pod restart four seconds earlier.
Also measured wal_writer_delay, which A-3 had asserted as matching without ever querying it, relabelled the A-6 control that moved 41 percent, noted A-8's nine-sample resolution, corrected D-1's RTO to the 41 seconds its own timeline shows, and added a correction banner to D-2. Every experiment document now links its evidence files with their real collection times, and the duplicate screenshots are documented as duplicates.

Twelve SVG architecture diagrams cover the experiments whose documents had little or no structure drawing, embedded under a 구조 heading with a shared convention file. Seven documents carried their concepts under narrative headings and now have an explicit 개념 section so they can be found.

The forward upgrade to 26.7.3 was zero downtime across 87 samples, and since databasechangelog stayed at 210 the rollback to 26.7.0 also succeeded, which narrows D-2's conclusion: rolling back fails when the schema moved, not because of the version number. The row count is the check.
Role changes never reach the upstream through request repetition; the session is a snapshot taken at login and only a new session picks up the new claim. Auditing the docs also surfaced that Prometheus scrapes only keycloak, kubelet, node-exporter and itself, so the B-layer experiments have no metrics to screenshot rather than missing screenshots.

Five simultaneous refreshes with one token return a single 200, and that winner's new token is already dead. Reuse detection removes the client session while the user session stays, which is why the other responses read Session doesn't have required client rather than a reuse error.
Comparing policies shows rotation off passes all five and keeps the session, while raising refreshTokenMaxReuse to one still destroys it. Since no retry can recover a removed client session, Q2's own criterion resolves to a lock, and a database row lock is the natural place because its lifetime is tied to the connection.
