DongHyeonkaandClaude Opus 5 6f6ab86345 docs(guides): reproduction guides for all 26 experiments 
Written by subagents running under the writing-practitioner-guides skill,
one guide per experiment, 22,566 lines. Each walks a reader from baseline
capture through injection, injection verification, observation and recovery.

Section 3 carries the weight in most of them. Injection failed silently nine
times in this lab, and a failed injection looks exactly like no effect — so
the guides verify the target is actually in the intended state before
reading any result. A-4 makes virsh list the only proof because the node
reads Ready for 40 seconds after the machine is off; A-5 makes the packet
counter the sole go/no-go because a rule on the wrong node produces an empty
result that reads like a finding; A-6 quotes the run where 적용완료 was
printed between four Cannot find device "eth0" lines.

The traps the guides are built around are ones that invert a conclusion
rather than merely annoy:

  A-0   emptying the session table without a restart leaves cache entries
        that get counted as replication arriving
  A-2   dropping -o /dev/null fuses body and status into one string
  A-3   presence of "ready to accept connections" instead of its timestamp
  B-2   row count alone reads an UPDATE as nothing having happened
  B-4   tr ',' '\n' splits ["admin","editor"] so only admin is seen
  B-7   no login screen means the cookie died and SSO re-authenticated
  C-1   counting sessions without joining realm counts your own kcadm one
  D-1   kubectl exec without -i restores nothing and still exits 0
  D-4a  "ran with error output" is what success looks like

Every quoted block is copied from docs/evidence/ and marked 실측; reshaped
commands are marked 미검증 rather than passed off as measured. Where a source
document carries a ★ correction the guides follow the corrected claim — A-7's
REVOKED_TOKEN hypothesis, C-1's session count, B-2's schema attribution.

Two hazards are stated rather than smoothed over: B-6 deletes a key that
cannot be recreated, and D-1/D-4 need host sudo, which asks for a password,
so those steps say a person must type them.

Audit over all 26: 672 interpretation pairs, 486 evidence citations, 117
undo sections, and zero occurrences of the patterns the skill forbids —
no python data processing, no deprecated kubectl get endpoints, no
placeholders, no bare kcadm.

DongHyeonkaandClaude Opus 5 8062cc9a19 docs(guides): bring the seven setup guides in line with the practitioner skill 
The guides were written before the skill existed and a scored audit found
three gaps. Fixed by a subagent running under the skill, with measured
values, versions, IPs and quoted output declared off limits.

The big one: every step showed a command and its output, and almost none
said which line to look at or what it meant. 64 interpretation pairs added
across the seven files, weighted where the reading is hardest — 20 in the
Keycloak stage, where a Secret existing and a pod having received it are
different facts.

Only the extracting form of curl appeared. Where the reader meets a response
for the first time the guides now open with curl -I or curl -v and name the
lines worth reading; -w '%{http_code}' survives only where the code is a
value being compared — two upstream nodes against each other, or the 900-run
control loop.

Listing Secret keys went from a three-stage pipe to kubectl describe secret,
which prints the key names and their byte counts in one native command
without exposing a value.

And a tool assumption: jq and yamllint are installed on neither the lab host
nor the guests. The guides now say so where JSON is read by eye, rather than
sending the reader to install something mid-diagnosis. cloud-init schema is
on the guests and is now the guest-side check.

Also removes a stray Playwright screenshot committed at the repository root
in 919547a; the evidence copy under docs/evidence/b7a-orphan-session/ is the
one the document references.

Four things the audit left standing are recorded in the agent's report rather
than papered over — notably that 04's reload measurements are stated without
a reproduction procedure, and that 05 and 06 reference each other as
prerequisites.

DongHyeonkaandClaude Opus 5 88b7bd4bf0 docs(guides): hands-on guides for the seven setup stages 
The experiment documents record what was found. These record what to type to
reproduce it, in folders per stage.

Two kinds of command are kept apart. 하기/확인 is what somebody actually types
at a terminal — short, one at a time. 근거를 재려면 is the long measuring form
this lab used to put evidence in a document, marked as not needed day to day.
The same split applies to curl: -I to look once, -w '%{http_code}' only when
comparing across repetitions.

No placeholders. Where a value is needed the command that produces it is
given, and secrets are checked by length rather than printed:

  TOKEN=$(ssh kc-lab-1 'sudo cat /var/lib/rancher/k3s/server/node-token')
  echo "${#TOKEN} 자"

Stage 05 verifies resources in layers, because a Secret existing and a pod
having received it are different facts: keys, then length, then the value
inside the container, then which env var came from which Secret. Same for
workloads — Deployment to ReplicaSet to Pod, with the seven ReplicaSets this
cluster actually carries as the worked example.

Two commands were wrong and re-running them caught it. kubectl get endpoints
prints a deprecation warning on v1.33+, so the guide uses describe svc and
EndpointSlice. And the Keycloak image has no curl, so reading metrics from
inside the container fails with exit 127 — the guide asks Prometheus instead,
or runs a throwaway curl pod.

Read-only checks were executed against the running lab and their output is
quoted verbatim. Creating commands could not be re-run without destroying the
lab, so they are the ones used at build time; the README says which is which.

DongHyeonkaandClaude Opus 5 cdac9b8178 docs: give the twelve experiments that had no architecture diagram one 
An audit against the standard the series set — concepts, procedure,
commands, architecture diagram, evidence table, terminal output — found the
three new experiments met it while twelve of the original ones had no
diagram at all: A-0, A-1, A-3, A-4, A-5, A-6, A-8, B-0, B-2, B-7, C-2, D-2.

Each now has one drawn from what that experiment actually found, not filler:
A-0 shows sharing going through PostgreSQL rather than between the caches;
A-3 the gap between the 200 and the WAL flush, with both failed injections;
A-5 the three silent injection failures; A-6 the two places latency is
multiplied; B-0 the repository keyed by principal with no session id; B-2
the primary key that causes the overwrite; D-2 why the rolling update
stopped the accident halfway.

Also corrected the index's stale claim of 11 experiments without a
screenshot — it is 14, and the reason is recorded: those experiments were
measured from terminals, the database and logs, and the observability stack
does not scrape Redis, the BFF or PostgreSQL, so there is no console to
photograph.

DongHyeonkaandClaude Opus 5 e9baac21d5 docs(d4a): the deploy hook works — issuance to serving drops from 38m25s to 1-2s 
D-4 named the fix and never ran it. Running it:

  /etc/letsencrypt/renewal-hooks/deploy/reload-nginx.sh
    #!/bin/sh
    nginx -t && nginx -s reload

certbot reports "Hook 'deploy-hook' ran", the master stays at PID 585 and
the worker is replaced 28829 -> 37252, and the served certificate changes.

One trap worth naming: certbot prefixes the hook output with "ran with error
output" whenever the hook writes anything to stderr, and nginx's routine
types_hash warning goes to stderr. Everything inside is success — "test is
successful", "signal process started". A monitor that greps for "error"
would read a working hook as a failure. The worker PID is what to check.

Timing needed a clock correction. test-server has NTP off and runs 106
seconds fast; the dev machine matches Google and the Let's Encrypt ACME
endpoint exactly. Corrected, the hook's nginx -t lands at 12:27:50 UTC
against the new certificate's SCT at 12:27:49.054 — one second. The
correction validates itself: uncorrected, the hook would have run 104
seconds before the certificate existed.

That same skew is why D-4's gap was reported 106 seconds short; corrected to
2305s in the previous commit.

Remaining and left alone: whether certbot-renew.timer performs a real
renewal, which cannot be tested for about 89 days.

DongHyeonkaandClaude Opus 5 3d7778bd3c docs(d4): correct the gap to 38m25s — the two timestamps came from different clocks 
The 2199 seconds reported for D-4 subtracted a test-server timestamp
(archive/cert2.pem mtime) from a dev-machine timestamp (the serial change
observed by the poll), without noting they are different clocks.

Checked against external references: the dev machine matches Google and the
Let's Encrypt ACME endpoint to the second, while test-server is 105 seconds
fast and reports NTPSynchronized=no. Three round-trip measurements put the
offset at +106.1s every time.

Corrected:

  new certificate written to disk  08:20:27 UTC   (mtime 17:22:13 KST - 106s)
  actually served                  08:58:52 UTC   (dev observation, no correction)
  gap                              2305s = 38m25s

The correction validates itself in D-4a, where the new certificate's SCT —
signed by CT logs on their own accurate clock at 12:27:49.054 GMT — lands
one second before the skew-corrected hook time. Without the correction the
hook would appear to have run 104 seconds before the certificate existed.

Updated across the experiment doc, the index, the follow-up doc, the verdict
evidence file and the SVG.

DongHyeonkaandClaude Opus 5 919547a025 docs(b7a): the orphan sessions can be deleted — oauth2-proxy just cannot do it 
B-7 stopped at "could not delete the server-side session". The reason it
gave was right: the ticket carries the session id, the ticket is encrypted
with the cookie secret, so after a rotation the proxy cannot work out which
Redis key to remove. But that is a limitation of the proxy, not of Redis.

Measured across two rotations:

- The orphan does expire. TTL falls one second per second and is not
  refreshed by requests (the startup log says refresh:disabled, and
  --cookie-refresh is unset), so it dies exactly one hour after creation.
- An operator can delete it. `redis-cli del` returned 1, dbsize went 2 to 1,
  and the live session answered /oauth2/userinfo with 200 immediately after.
- But nothing in Redis says which key is the orphan. Same name prefix, same
  type, the same 3510 bytes, and the values are encrypted.
- TTL is the only signal, and because it is never refreshed it is an exact
  function of creation time. Anything created before the rotation is an
  orphan. Derived creation time 11:30:26 against the AuthSuccess log line at
  11:30:27 — one second out. The rule was then run and removed the orphan
  while leaving the live session.
- They accumulate: the session that survived the first rotation became the
  orphan of the second.

The caveat is recorded too: turning on --cookie-refresh breaks the
derivation, and at that point flushing and forcing everyone to
re-authenticate is the more honest option.

DongHyeonkaandClaude Opus 5 b9f4ef7bc2 docs(a7a): the volatile refresh failure is a client-scope lookup, not REVOKED_TOKEN 
A-7 left the cause as a hypothesis and said to confirm it with the statement
logging A-3 used. Doing that shows the hypothesis was wrong.

Login issues no SQL at all in volatile mode. Refresh issues exactly one
statement, and it is not the one A-7 guessed:

  select cscme1_0.SCOPE_ID from CLIENT_SCOPE_CLIENT cscme1_0
   where cscme1_0.CLIENT_ID=$1 and cscme1_0.DEFAULT_SCOPE=$2
   parameters: $1 = '131a9912-...', $2 = 'f'

REVOKED_TOKEN never appears. DEFAULT_SCOPE='f' means this is the optional
client scope list, which refresh needs because it recomputes which scopes go
into the new access token.

The larger finding is that A-7's table was conditional and did not say so.
The single statement is issued once and then cached, so the same
configuration produces three different outcomes depending only on cache
warmth — all three reproduced:

  fully cold      login 400  (select ce1_0.ID from CLIENT ...)
  CLIENT warm     login 200, refresh 500  <- what A-7 measured
  fully warm      login 200, refresh 200

So "volatile means you can log in without a database" is also conditional:
on a cold start the client lookup itself fails. In each case the Keycloak
log names the failing SQL directly, so this is determined rather than
inferred.

A-7 keeps its original wording with a correction banner above it, so what
was mis-guessed and why stays visible.

DongHyeonkaandClaude Opus 5 9dbee18a42 docs(b4): item 3 is no longer unmeasured — link it to the follow-up result 
B-4 left role propagation open because oauth2-proxy was not deployed yet.
B-7 deployed it and the follow-up measured it: the value does not change
with request count, only when a new session is created.

DongHyeonkaandClaude Opus 5 905392947d docs: close the three untested items — all three are now measured 
D-2 forward upgrade and B-4 role propagation were filled earlier. D-4 forced
renewal was the third, and it needed a person at the keyboard because the
host asks for a sudo password.

It turned out to hold the largest finding of the three: the renewal
succeeded and went unserved for 36 minutes 39 seconds, because nothing in
the setup reloads nginx — no ExecStartPost, three empty hook directories,
no nginx plugin. And the half of the plan's question that was still an
expectation is now a measurement: the reload is graceful, 8856 connections

DongHyeonkaandClaude Opus 5 faf55dc1be docs(d4): the renewal succeeded and was not served for 36 minutes 39 seconds 
The forced renewal did work. What did not work was anything making nginx
notice.

  disk     cert2.pem written 2026-09-04 17:22:13 KST
  network  old serial through 08:58:47 UTC, new serial from 08:58:52 UTC
  gap      2199 seconds, and the old certificate was observed 428 times in it

The gap closed only because a person ran `nginx -s reload`. Nothing else
would have: certbot-renew.service is just `ExecStart=/usr/bin/certbot -q
renew` with no ExecStartPost, all three of renewal-hooks/{deploy,post,pre}
are empty, and certbot 5.7.0 here has no nginx plugin (dns-cloudflare,
manual, null, standalone, webroot). Three paths, all empty. Any one of them
would have been enough.

nginx holds the certificate in memory from startup, and certbot swaps the
live/ symlink rather than the path — so the config still looks right while
the served certificate is stale. Master 585 and worker 586 sharing a start
time 22.4 hours old is what proved no reload had happened.

This is invisible for 88 days. The timer ran twice today and exited
0/SUCCESS both times, because a renewal is not due yet. The day it becomes
due, the symptom is an expired certificate and the log still says SUCCESS.

The other half of the plan's question now has a measurement rather than an
expectation. The reload is genuinely graceful: 8856 polled connections, zero
non-200, p95 205.7ms before against 204.3ms after. And an in-flight request
— 845KB pulled at 20k/s, so still transferring 12 seconds in when the reload
landed — completed with all 845361 bytes over a single connection.

The earlier note that nginx reload "is graceful by design but must not be
written that way without checking" was right to hold back. The neighbouring
belief, that renewing gets the new certificate served, was the one that was
false, and there was no way to tell in advance which it would be.

Adds diagrams/d4-renewal-gap.svg and evidence 09-13.

DongHyeonkaandClaude Opus 5 0d84921a56 docs(d4): the renewal unit has no reload, and nginx has not reloaded in 22 hours 
The forced renewal did not change the certificate being served — 161 serial
samples over 13 minutes, all identical, notBefore still Sep 3.

Two things were readable without sudo and both matter.

nginx has never been reloaded: master 585 and worker 586 share a start time
and both are 80529 seconds old. A reload keeps the master and replaces the
workers, so the original fork still being there means no reload has happened
since Sep 3 19:00. nginx reads the certificate at startup and holds it in
memory; without a reload it serves the old one no matter what is on disk.

And the unit that is supposed to renew has nothing that would reload it:

  [Service]
  Type=oneshot
  ExecStart=/usr/bin/certbot -q renew
  PrivateTmp=true

No ExecStartPost, no --deploy-hook. The timer runs twice a day and exited
0/SUCCESS both times today, which is precisely why this stays invisible —
the renewal is not due for 88 days, so nothing has failed yet.

What remains undetermined is whether the user's --force-renewal failed, or
succeeded and left new files that nginx never picked up. Telling those apart
needs /etc/letsencrypt, which is root-only. If it is the latter, that is the
most valuable thing this lab has produced: "renewal succeeded" and "the new
certificate is being served" are different events.

CT logs looked like a way around the permission problem and were not: the
served certificate carries two valid SCTs, yet crt.sh returns zero rows for
auth.hyeonworks.com. Same shape as A-2's `up` metric — the observing tool
sees a subset of the truth.

Also recorded: 76 in-flight failures at 08:15:04 are a local artifact, not a
server event. The concurrent 0.2s poll was clean across the same second,
num_connects was 0, and time_total was 50 microseconds. Not reproducible in
100 retries. The monitor now records curl's exit code so a recurrence is
diagnosable.

DongHyeonkaandClaude Opus 5 716e62524a docs(d4): measure the controls before the injection that needs a password 
The forced renewal needs sudo on the host, and the host asks for a password.
That blocks the injection, not the experiment — the part worth doing first
was the control anyway.

Control 1 — new connections, 0.2s x 900 over 180s: 900/900 = 200, zero
failures. The noise floor is 0, so a single non-200 during the renewal can
be attributed to the renewal. Without this the observation would have been
uninterpretable, which is the mistake A-6 made calling a -41% control
"no effect" and A-8 made claiming zero-downtime from 9 samples.

Control 2 — the poll cannot answer the question the plan actually asked.
TLS handshakes were 900/900, meaning every request is a fresh connection,
so it measures "are new connections accepted", not "what happens to a
request already in flight". A separate device: the 845KB admin console
bundle pulled at --limit-rate 20k, holding one request open for 42 seconds.
Baseline 200 / 845361 bytes / 1 connection.

Monitors are running under setsid, and stop three minutes after the
certificate serial changes.

DongHyeonkaandClaude Opus 5 74c9b3cea7 docs: replace prose placeholders in reproduction steps with executable commands 
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.

DongHyeonkaandClaude Opus 5 f3f3a8da46 docs: re-measure B-4 role propagation and record it as evidence 
The twelve-request result and the post-reauth value were printed in the document but never written to a file; the audit flagged it as a conclusion standing without evidence. Measured again with timestamps into 03-b4-role-propagation.txt, which also surfaced a 107-second clock skew between the browser host and the lab host that the file now records so the two timelines can be compared.

DongHyeonkaandClaude Opus 5 e0d27d47ce docs: correct the places where documents contradicted their own evidence 
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.

DongHyeonkaandClaude Opus 5 98a74e90a5 docs: fill the untested items and record why the B layer has no graphs 
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.

DongHyeonkaandClaude Opus 5 4864d837f1 docs: D-4 — the certificate is fine and the renewal itself went untested 
Three SAN entries and no wildcard is the constraint that cost something real in B-7, where oauth2-proxy had to borrow Grafana's app2 hostname because a fourth name was not available. The served chain is four deep and verifies, so fullchain.pem is configured rather than the cert.pem mistake that only breaks clients without a cached intermediate.

The forced renewal and the reload behaviour could not be measured because sudo on the host asks for a password, the same silent failure first noticed in B-7. nginx reload is graceful by design, but this lab has repeatedly shown that by design is not the same as measured, so it is recorded as untested rather than assumed.

DongHyeonkaandClaude Opus 5 027c24ee27 docs: D-3 — only RBAC actually hides anything 
Every secret in the lab prints in four commands, while kubectl describe shows just a byte count and creates the impression that something is hidden. k3s reports encryption at rest disabled and the plaintext password is present in state.db, so one node disk carries the whole cluster's secrets, and inside the pod they are ordinary environment variables visible to exec, /proc and crash dumps.

The default service account cannot read secrets, which makes RBAC the one control doing real work here and the thing worth tightening.

DongHyeonkaandClaude Opus 5 df140ab218 docs: D-2 — rolling back the image does not roll back the schema 
Downgrading from 26.7.0 to 26.0 fails with liquibase ValidationFailedException on a changeset checksum, which is stricter than an unknown migration: the old version knows the changeset but its definition differs. The pod goes CrashLoopBackOff and never starts.

The StatefulSet stopped the rollout at the first pod, so the other kept serving and the front door stayed at 200, which replica 1 would not have done. The failed start never touched the schema, so restoring the image was enough; had the migration already applied, the D-1 database restore would have been the only way back.

DongHyeonkaandClaude Opus 5 df5af95cb3 docs: D-1 — an empty database still answered 200 
Dropping the schema left Keycloak serving realm metadata and JWKS from its Infinispan cache, so the front door stayed at 200 while only the paths that read the database failed. That is a different shape from A-2, where the connection itself broke and readiness pulled the pods out of the Service; here the connection is fine and the tables are simply gone, which the health check does not notice.

Restoring the pg_dump took one second with zero errors and no pod restart, and the row counts matched the backup exactly, sessions included. The real RPO is the backup interval plus the synchronous_commit loss measured in A-3, and this dump sits in the host's /tmp, which is the same failure domain as the thing it protects.

DongHyeonkaandClaude Opus 5 6c310c93b7 docs: C-2 — nothing propagates because nobody implemented the receiving end 
Neither client had a backchannel logout URL and the BFF has no oidcLogout configuration, so the three candidate paths all answer 302, which is the authentication redirect rather than a handler. Setting the URL on the identity provider alone changed nothing: with a live session, logging the user out emptied the Keycloak side and left the Redis session untouched.

Reachability is not the blocker here, since a Keycloak pod fetches the app's public URL with a 200, but that is a property of this tailnet split-DNS lab and is the assumption most likely to fail in production, where it fails silently.

DongHyeonkaandClaude Opus 5 e856e7af4d docs: C-1 — killing the SSO session logs nobody out 
One user session carries a client session per application, so visiting the second app skips the login screen. Deleting the identity provider session leaves both application sessions untouched and both apps keep serving, because the identity provider, the application session and the access token each have their own lifetime.

That inverts the B-2 finding: there the app session was cleared and the surviving SSO session let the user straight back in. Either way, clearing one side leaves the other. It also means an identity provider outage is a single point of failure for logging in, not for already-authenticated users, and the failure arrives late and all at once.

DongHyeonkaandClaude Opus 5 bcb563a04e docs: B-7 — the cookie secret has no overlap window and rotation orphans sessions 
oauth2-proxy carries the authorization request in a signed cookie, so the callback can land on a different replica and still succeed, which is the opposite of the BFF failure in B-0. Sharing is therefore just sharing one Secret.

Rotating it is all-or-nothing: --cookie-secret is singular, so there is no second key to read old tickets with, and the log shows both the validation failure and Error removing session, leaving the Redis session orphaned because the key cannot be derived from a ticket that will not decode.

Getting there required two diagnoses: the callback 502 came from the full session riding in Set-Cookie past nginx's buffer, and every earlier attempt to read nginx config returned nothing because sudo on the host asks for a password while the guests do not.

`nginx → Traefik` **2홉**이 운영 구조와 같다는 점이 이 배치의 핵심이다.
L7 프록시가 두 겹인 이유는 역할이 다르기 때문이다 — nginx는 바깥세상과의
접점(TLS·인증서·헤더)을, Traefik은 클러스터 내부의 동적 라우팅을 맡는다.

A-7a — volatile 모드에서 refresh 가 500 인 진짜 이유
=======================================================
수집: 2026-09-04 11:18 ~ 11:24 UTC · kc-lab-1 에서 sudo kubectl
A-7 이 남긴 가설
----------------
> **측정은 확실하지만 원인은 확정하지 못했다.** 유력한 후보는
> `REVOKED_TOKEN` 테이블이다 — refresh token 회전에서 이미 쓴 토큰인지
> 확인하려면 그 테이블을 봐야 하고, 그 경로는 캐시되지 않는다.
★ 이 가설은 틀렸다.
방법 — PostgreSQL 문장 로깅 (A-3 기법)
---------------------------------------
ALTER SYSTEM SET log_statement = 'all'; SELECT pg_reload_conf();
표식을 넣어 로그인과 refresh 가 각각 어떤 SQL 을 쏘는지 구분했다.
select 'MARK_LOGIN_START' ... 로그인 ... select 'MARK_LOGIN_END'
select 'MARK_REFRESH_START' ... refresh ... select 'MARK_REFRESH_END'
volatile 전환 확인
args: ["start","--features-disabled=persistent-user-sessions"]
로그인 200 · offline_user_session 행수 = 0 ← volatile 맞다
[측정 1] 로그인은 SQL 을 0개 쏜다
----------------------------------
11:18:49.461 statement: select 'MARK_LOGIN_START'
11:18:49.743 statement: select 'MARK_LOGIN_END'
↑ 사이에 아무것도 없다
realm·사용자·클라이언트가 전부 Infinispan 캐시에 있어 DB 를 안 본다.
[측정 2] ★ refresh 는 CLIENT_SCOPE_CLIENT 를 본다
--------------------------------------------------
11:18:52.009 statement: select 'MARK_REFRESH_START'
11:18:52.137 statement: BEGIN
11:18:52.137 execute <unnamed>/C_107:
select cscme1_0.SCOPE_ID from CLIENT_SCOPE_CLIENT cscme1_0
where cscme1_0.CLIENT_ID=$1 and cscme1_0.DEFAULT_SCOPE=$2
parameters: $1 = '131a9912-b578-4b9c-b16a-97518704077e', $2 = 'f'
11:18:52.148 execute S_2: COMMIT
11:18:52.253 statement: select 'MARK_REFRESH_END'
REVOKED_TOKEN 은 **한 번도 나오지 않는다.**
`DEFAULT_SCOPE='f'` 이므로 **선택적(optional) 클라이언트 스코프** 조회다.
[측정 3] 그 조회는 한 번뿐이다 — 캐시에 들어간다
-------------------------------------------------
연속 refresh 3회, 전부 200. 표식 사이 SQL:
statement: select 'MARK_R1'
statement: select 'MARK_R2'
statement: select 'MARK_R3'
statement: select 'MARK_R_END'
↑ SQL 0건
첫 refresh 가 캐시를 채우고, 이후로는 DB 를 보지 않는다.
════ 그래서 A-7 의 표 자체가 조건부였다 ════
같은 설정에서 **캐시 온도만으로 결과가 셋으로 갈린다.** 전부 측정했다.

[재현 A] 완전 냉시동 — 로그인부터 400
keycloak 재시작 → postgres 정지 → 로그인
로그인 400 {"error":"unauthorized_client",
"error_description":"Unexpected error when authenticating client"}
ERROR [org.keycloak.services] KC-SERVICES0015: Unexpected error when

[select ce1_0.ID from CLIENT ce1_0 where ce1_0.CLIENT_ID=? and ce1_0.REALM_ID=?]
→ A-7 은 "volatile 이면 DB 없이 로그인된다"고 적었지만,
**냉시동에서는 그것도 안 된다.**
[재현 B] ★ A-7 이 본 그 조건 — 로그인 200, refresh 500
keycloak 재시작 → (DB 살아있을 때) 로그인 1회 → postgres 정지 → refresh
로그인 200
refresh 500 {"error":"unknown_error"}

★ 로그가 실패한 SQL 을 직접 지목한다. CLIENT_SCOPE_CLIENT 다.
[재현 C] 완전히 더움 — 둘 다 200
refresh 를 3회 미리 돌려 캐시를 채운 뒤 postgres 정지
로그인 200
refresh 200 ← A-7 의 표와 정반대다
════ 결론 ════
1. **원인은 REVOKED_TOKEN 이 아니라 선택적 클라이언트 스코프 조회다.**
`CLIENT_SCOPE_CLIENT` 를 `DEFAULT_SCOPE='f'` 로 조회하는 그 한 문장이다.
2. **A-7 의 "volatile → refresh 500" 은 캐시가 차가울 때만 참이다.**
더워지면 200 이 된다. A-7 은 그 조건을 몰랐고, 그래서 표에 적지 않았다.
3. **"volatile 이면 DB 없이 로그인된다" 도 조건부다.**
냉시동에서는 400 이다. 클라이언트 조회조차 캐시에 없기 때문이다.
4. **일반화** — volatile 모드에서 DB 정지 시의 동작은 "무엇을 하느냐"가
아니라 **"그 경로가 이미 캐시를 채웠느냐"** 로 결정된다. 그래서 같은
명령이 재시작 직후와 얼마 쓴 뒤에 다른 답을 낸다. 이런 종류의 결과는
**한 번 재보고 표로 적으면 안 된다** — A-7 이 그렇게 했다.

# A-7a — volatile refresh 500 의 원인 확정 증거
2026-09-04 11:18 – 11:24 UTC
해설: [`docs/experiment-a7a-volatile-cause.md`](../../experiment-a7a-volatile-cause.md)
| 파일 | 무엇을 보여주는가 |
|---|---|
| `01-cause-determined.txt` | **가설이 틀렸다.** `REVOKED_TOKEN` 이 아니라 `CLIENT_SCOPE_CLIENT` 조회다. 문장 로깅으로 잡고, 실패 로그가 그 SQL 을 직접 지목한다. 그리고 **같은 설정에서 캐시 온도만으로 400/500/200 셋이 나온다** |
## 핵심 네 줄
1. **원인은 선택적 클라이언트 스코프 조회다.** `select cscme1_0.SCOPE_ID from CLIENT_SCOPE_CLIENT where CLIENT_ID=? and DEFAULT_SCOPE=?` — A-7 이 지목한 `REVOKED_TOKEN` 은 로그에 한 번도 안 나온다.
2. **로그인은 SQL 을 0개 쏜다.** refresh 만 이 한 문장을 쏘고, 그것도 **첫 번째만** 쏜다. 이후로는 캐시된다.
3. **A-7 의 표가 조건부였다.** 완전 냉시동이면 로그인부터 400, 캐시가 완전히 더우면 refresh 도 200. A-7 이 본 「로그인 200 · refresh 500」은 그 사이의 한 상태다 — 셋 다 재현했다.
4. **교훈** — volatile + DB 정지의 동작은 "무엇을 하느냐"가 아니라 **"그 경로가 캐시를 채웠느냐"** 로 갈린다. 한 번 재보고 표로 적으면 안 되는 종류의 측정이다.

`b0-bff-token-boundary.png` 와 동일 파일**이다 (md5 `9ed00537…`).
두 시점 모두 `accessTokenStoredOnServer: true` 인 같은 화면이라 바이트가 같다.
**그래서 이 png 는 "JDBC 전환으로 토큰이 공유된다" 를 단독으로 증명하지
못한다.** 그 증명은 `01-jdbc-store-deploy.txt`(테이블 생성)과
`03-plaintext-tokens.txt`(행에 토큰이 들어 있음)가 한다.
`b2-before-relogin.png` 는 B-1 의 캡처와 동일 파일이다.
