The existing 32 checks prove the deployment answers -- TLS, auth, quorum commit,
convergence, isolation, dashboards, backups. Not one wrote a signal and observed
an order change, so VISION.md:17 "Ranking is not a feature. It is a primitive."
was unverified. This adds a 60-item content-feed app and five assertions that
verify the product's semantics, on a hermetic standalone node.
Added
- tests/e2e/app/: fixture contract (60 items, 4 categories, each owning one
unoccupied 100-id embedding cluster), a deep-module harness owning the whole
lifecycle behind startApp(), the product page, and an app:dev entry point.
- tidal-stress/src/bin/feed-fixture.rs: seeds the catalog and emits brute-force
ground truth, reusing recall::embedding_for rather than adding a third copy of
the corpus generator (tidal/src/db/items.rs already holds a second).
- GroundTruth::from_ids: the oracle now serves sparse id sets. build() delegates,
so there is no transient copy even at 1M, and top_k indexes positionally.
- 10-ranking-semantics.spec.ts (5 hermetic checks) and
11-ranking-integrity.spec.ts (2 cluster tripwires).
- playwright.semantics.config.ts + CAP-016 demo beat (walkthrough 82s -> 90s).
Measured, not merely green
- like: index 59 -> 0, like_boost 2.0, with no sleep between write and read.
- decay: implied half-lives 7.0007 d and 14.0014 d against a schema declaring
7 d and 14 d, recovered from a 4-second window via H = t*ln2 / -ln(v2/v1) and
compared against the schema the node actually loaded, not a hardcoded copy.
- ANN: top-10 identical to brute-force cosine on all four probes; self-distance
0.0148-0.0197 against a 0.05 tolerance.
- rank: dense 1..60 on standalone vs [1,1,1,2,2,3,4,3,4,5,6,5] on the cluster.
Three product findings, pinned and routed to @tidal-engineer
- BUG-018 (High) skip is durably accepted and query-time inert. Penalty is fully
implemented (ranking/profile.rs:227 -> executor/signal_values.rs:183, labelled
{signal}_penalty at executor/mod.rs:65) but skeleton() sets penalties: vec![]
(ranking/builtins.rs:62) and none of the 27 built-ins overrides it. So
VISION.md:187 "negative signals are equal citizens" holds for no shipped
profile. Same anti-pattern as the reseed defects and scatter_merge: a guard
present on one path, absent on its sibling.
- BUG-019 (Medium) three built-ins read signals this schema does not declare --
trending/share_velocity, hidden_gems/completion, controversial/dislike -- so
those terms are permanently 0 and trending ranks on view_velocity alone.
- BUG-020 (Low) for_you declares Scan{sort_field:"created_at"} but ignores a
created_at metadata value; an order matching neither id-asc nor
created_at-desc came back strictly id-ascending.
Two assertions therefore report a gap rather than a success, written as tripwires
whose failure message says what to do when the gap closes. The rank defect is
localised, not fixed: scatter_merge (cluster/node.rs:7542) returns a merged slice
without re-stamping rank while scores stay correctly ordered, so the fault is the
missing stamp and not the merge's sort.
Notes
- Hermetic by construction: its own config, because FullConfig.projects is not
filtered by --project and globalSetup publishes credentials into the main
process that forked workers inherit -- so a setup project cannot replace it,
and weakening globalSetup would destroy the fail-loud behaviour that is its
purpose. Verified with KUBECONFIG=/nonexistent and all E2E_* unset.
- Never touches the deployed corpus: skip is permanent: true, so seeding it into
production would be irreversible.
- The page contains no sort, no hostname and no credential; the harness proxy
injects auth server-side so no bearer reaches a browser or a capture.
- Schema comes from k8s/cluster/schema-configmap.yaml, asserted at 1536 dims;
tidal-server/config/default-schema.yaml declares 128 and would 422 every write.
Verification: 5 semantics + 34 regression + 10 demo captures green; tsc clean;
tidal-stress clippy clean under clippy::all=deny with unwrap_used=deny; 2101
tidaldb lib tests; preflight 10/10 perfect; render 90.05s/2700 frames with zero
empty boundary frames; zero orphan processes or temp dirs after teardown.
20 KiB
Deploy verification
Walk this top to bottom. Every command here was executed against the live
orchard9-k3sf deployment and its output recorded — nothing is aspirational.
Each check states what it proves, the command, and what you should see. If a check fails, its If it fails line says where to look.
Sections 1–8 verify what is deployed now. Section 9 covers operator authority plus the two features that are committed but inert on the running image — kept separate so their absence is not mistaken for a regression.
Run it automatically first
Every check below is also a Playwright test that asserts the same thing and records what it observed. Run that first; walk the manual steps when something fails, or when you want to see a layer for yourself.
export KUBECONFIG=~/.kube/orchard9-k3sf.yaml
npm install && npx playwright install chromium # first time only
cargo build -p tidalctl # section 7 needs the binary
npm run test:e2e:list # discovery: syntax, imports, registration
npm run test:e2e:smoke # cluster plane + public plane + a quorum write
npm run test:e2e # the whole runbook, 34 checks, ~55 s
Credentials are read from the cluster by globalSetup, so nothing is pasted
into a shell. A missing prerequisite fails loudly rather than skipping a check.
The product, not just the deployment
Everything in this runbook verifies that the deployment answers. None of it verifies that the database does the thing it exists to do, so there is a second, separate suite for ranking semantics:
npm run test:e2e:semantics # 5 checks, ~14 s, NO cluster required
npm run app:dev # open the same app by hand and click Like
It boots a throwaway standalone node, seeds a 60-item fixture catalog with
deterministic vectors from tidal-stress's own generator, and asserts that a
signal write reorders the next query, that decay is applied at the declared
half-life, and that ANN results equal brute-force cosine. It has its own config
(playwright.semantics.config.ts) precisely because it must run with no cluster
and no credentials — npm run test:all runs both suites.
It deliberately never touches the deployed cluster: skip is declared
permanent: true, so seeding signals into the live corpus would be
irreversible. Two of its five checks report a product gap rather than a success
(skip is inert under all 27 built-in profiles; see demo/capability-inventory.md
BUG-018), and one cluster-targeted tripwire pins the duplicated rank
(BUG-020) with its root cause in scatter_merge.
The HTML report at playwright-report/ carries the transcript of every command
the suite ran, which is the evidence trail this document used to describe in
prose.
There is one deliberate asymmetry. The manual steps tell you to sleep 8 after
a kubectl port-forward; the harness polls the port until it accepts a
connection instead. Same fix, deterministic rather than empirical — and it is
why the automated pass takes 40 s where the manual walk takes several minutes.
A stakeholder walkthrough of the same evidence lives in demo/ — see
demo/storyboard.md for what it shows and demo/visual-audit.md for how each
frame was reviewed.
0. Setup
export KUBECONFIG=~/.kube/orchard9-k3sf.yaml
export TIDAL_API_KEY=$(kubectl -n tidaldb-cluster get secret tidaldb-credentials \
-o jsonpath='{.data.TIDAL_API_KEY}' | base64 -d)
# Confirm you are pointed at the right cluster before anything else.
kubectl config current-context
TIDAL_API_KEY is the data-plane bearer. It is not an operator credential —
see §9.2.
1. Cluster is up and converged
Proves: all three voters are serving, and no node is behind or reseeding.
kubectl -n tidaldb-cluster get pods -l app.kubernetes.io/name=tidaldb \
-o custom-columns=NAME:.metadata.name,READY:.status.containerStatuses[0].ready,RESTARTS:.status.containerStatuses[0].restartCount
Expect three pods, READY=true. Restart counts are cumulative since the last
roll — a stable non-zero value is fine, a climbing one is not.
NAME READY RESTARTS
tidaldb-0 true 1
tidaldb-1 true 0
tidaldb-2 true 1
Then the authoritative per-node view. Query each pod directly — see §1.1 for why the aggregated view is not trustworthy here:
for i in 0 1 2; do
PORT=$((19700+i))
kubectl -n tidaldb-cluster port-forward tidaldb-$i $PORT:9500 >/dev/null 2>&1 &
PF=$!; sleep 8
printf 'tidaldb-%s: ' "$i"
curl -sk --max-time 10 -H "Authorization: Bearer $TIDAL_API_KEY" \
"https://127.0.0.1:$PORT/cluster/status/local" \
| python3 -c "
import json,sys
d=json.load(sys.stdin)
print('region=%-11s reseed=%-5s' % (d.get('region'), d.get('reseed_required')), end='')
for r in d.get('shards') or []:
print(' g%s[app=%s lag=%s ldr=%s]' % (r.get('shard'), r.get('applied_events'),
r.get('lag_events'), r.get('leader')), end='')
print()"
kill $PF 2>/dev/null; wait $PF 2>/dev/null
done
Pass: every pod reports reseed=False and lag=0 on every group, all naming
the same leader. Observed:
tidaldb-0: region=tidaldb-0 reseed=False g0[app=13324724 lag=0 ldr=tidaldb-2] g1[...lag=0...] g2[...lag=0...]
tidaldb-1: region=tidaldb-1 reseed=False g0[app=13324724 lag=0 ldr=tidaldb-2] g1[...lag=0...] g2[...lag=0...]
tidaldb-2: region=tidaldb-2 reseed=False g0[app=13322237 lag=0 ldr=tidaldb-2] g1[...lag=0...] g2[...lag=0...]
The 8-event difference on g0 between the leader and its followers is the
leader's own un-shipped tail, not lag.
If it fails: reseed=True that survives a restart is the m11p5 livelock
signature — see docs/runbooks/cluster.md §8. lag climbing on one node means
that follower is not keeping up.
Sleep 8, not 4. A shorter wait races
port-forward's bind and produces an empty body that reads exactly like a dead node. Two separate false alarms during this deploy came from exactly that.
1.1 Known caveat: the aggregated view under-reports peers
GET /cluster/status can report a peer it holds no frontier report for as
applied_events: 0, then derive lag against that zero — so a converged
peer appears to be the leader's entire history behind, sometimes labelled
reachable: false / partitioned: true.
Observed on this deployment: two healthy nodes shown as UNREACHABLE PARTITIONED at 13.3M lag, while every node's own /cluster/status/local
reported lag=0 and pod-to-pod connectivity was open with nothing logged.
tidalctl cluster-status detects that signature and prints NO REPORT (aggregated view; query the node directly) instead of repeating it as lag. Do
not open an incident on NO REPORT before running the §1 per-pod loop. This is
an open reporting defect, tracked in docs/ops/observability.md §4.
2. Public endpoint and TLS
Proves: the hostname resolves publicly and serves a certificate a normal client will accept.
dig +short tidaldb.threesix.ai
Expect all three node IPs (order varies):
208.122.204.172
208.122.204.173
208.122.204.174
If your workstation runs a split-DNS resolver (Tailscale MagicDNS will do this),
dig may succeed while curl cannot resolve. Confirm public resolution
independently:
curl -s -H 'accept: application/dns-json' \
'https://cloudflare-dns.com/dns-query?name=tidaldb.threesix.ai&type=A' \
| python3 -c "import json,sys; print([a['data'] for a in json.load(sys.stdin).get('Answer',[])])"
Certificate identity:
# Connect by IP with SNI, so this works even when the local resolver lags.
echo | openssl s_client -connect 208.122.204.172:443 \
-servername tidaldb.threesix.ai 2>/dev/null \
| openssl x509 -noout -subject -issuer -enddate
Pass: subject=CN=tidaldb.threesix.ai, issuer Let's Encrypt, notAfter at
least 30 days out. Observed notAfter=Nov 20 04:03:50 2026 GMT.
If it fails: cert-manager uses the dns01 solver (letsencrypt-prod), not
http01 — http01 cannot work behind a gateway gate that rejects unknown callers,
because it rejects the ACME challenge too. Check
kubectl -n tidaldb-cluster get certificate tidaldb-public-tls.
3. Authentication behaves correctly
Proves: the data surface is credential-gated and the admin surface is not published at all.
Use --resolve if your local resolver lags; it still validates the certificate.
R="--resolve tidaldb.threesix.ai:443:208.122.204.172"
B="https://tidaldb.threesix.ai"
printf 'health (open) %s\n' "$(curl -s -o /dev/null -w '%{http_code}' --max-time 15 $R $B/health)"
printf 'search no bearer %s\n' "$(curl -s -o /dev/null -w '%{http_code}' --max-time 15 $R "$B/search?query=a&limit=1")"
printf 'search bad bearer %s\n' "$(curl -s -o /dev/null -w '%{http_code}' --max-time 15 -H 'Authorization: Bearer wrong' $R "$B/search?query=a&limit=1")"
printf 'search good bearer %s\n' "$(curl -s -o /dev/null -w '%{http_code}' --max-time 20 -H "Authorization: Bearer $TIDAL_API_KEY" $R "$B/search?query=a&limit=1")"
Pass: 200, 401, 401, 200.
Admin and metrics surfaces must be unroutable from the internet:
for p in /cluster/status /cluster/members /metrics /openapi.json; do
printf '%-18s %s\n' "$p" "$(curl -s -o /dev/null -w '%{http_code}' --max-time 15 $R "$B$p")"
done
Pass: 404 for all four. A 200 on /cluster/status would be leaking
leader identity, membership and seqnos to the internet; a 200 on /metrics
would be leaking corpus size unauthenticated.
If it fails: the path allowlist lives in k8s/cluster/ingress.yaml. Only the
data paths are published, deliberately.
3.1 A real write, end to end
curl -s --max-time 25 -X POST \
-H 'content-type: application/json' \
-H "Authorization: Bearer $TIDAL_API_KEY" \
-H 'x-tidal-ack: quorum' \
-d '{"entity_id":999000099,"metadata":{"title":"deploy verification","category":"probe"}}' \
$R "$B/items" -o /dev/null -w 'quorum write %{http_code}\n'
Pass: 201. This is the strongest single check in the document — it proves
DNS, TLS, the gateway, the backend TLS hop, authentication, and quorum
replication in one request.
4. Network isolation
Proves: the unauthenticated metrics port and the peer plane are not reachable from arbitrary pods.
kubectl -n tidaldb-cluster get networkpolicy tidaldb
PIP=$(kubectl -n tidaldb-cluster get pod tidaldb-0 -o jsonpath='{.status.podIP}')
# A pod in an unrelated namespace must NOT reach :9091.
kubectl -n threesix exec gitea-0 -- \
sh -c "wget -qO- --timeout=5 http://$PIP:9091/metrics 2>&1 | head -1"
Pass: Connection refused. Before the policy existed this returned
# HELP tidaldb_uptime_seconds … from any pod in the cluster.
The scraper must still get through:
kubectl -n observability exec deploy/vmagent -- \
sh -c "wget -qO- --timeout=6 http://$PIP:9091/metrics 2>/dev/null | grep -c '^tidaldb_'"
Pass: a few hundred series (observed 353).
Do not test pod-to-pod reachability with
/dev/tcpundersh. The container'sshis dash, which has no/dev/tcp, so it reports failure for a port that is open. That false negative briefly looked like a cluster partition during this deploy. Usebash -cexplicitly.
5. Metrics and dashboard
Proves: the series exist with the labels the dashboard queries, and the dashboard is loaded.
kubectl -n observability port-forward svc/vmsingle 8428:8428 >/dev/null 2>&1 &
sleep 6
curl -s -G 'http://127.0.0.1:8428/api/v1/series' \
--data-urlencode 'match[]=tidaldb_health_ok' \
| python3 -c "import json,sys; d=json.load(sys.stdin)['data']; print(len(d),'series'); print(sorted(d[0]))"
Pass: non-zero series, labels including namespace, pod, container,
partition_id. The dashboard's $namespace/$pod variables depend on those
exact names.
Dashboard presence (needs the Grafana admin password):
PW=$(kubectl -n observability get secret grafana-admin -o jsonpath='{.data.password}' | base64 -d)
kubectl -n observability port-forward deploy/grafana 3000:3000 >/dev/null 2>&1 &
sleep 6
curl -s -u "admin:$PW" 'http://127.0.0.1:3000/api/dashboards/uid/tidaldb-overview' \
| python3 -c "
import json,sys
d=json.load(sys.stdin); db=d['dashboard']
print('LOADED:', db['title'], '| folder:', d['meta'].get('folderTitle'),
'| panels:', sum(1 for p in db['panels'] if p['type']!='row'))"
Pass: LOADED: tidalDB — usage, errors, and cluster health | folder: Databases | panels: 13.
If it fails: the dashboard is a key on the grafana-database-dashboards
ConfigMap; Grafana's file provider rescans every 30s. Source of truth is
docs/ops/grafana-tidaldb.json.
6. Logs are queryable
Proves: log lines are reaching the platform.
kubectl -n tidaldb-cluster logs tidaldb-0 --tail=20
Pass: readable lines, no raw \x1b[ escape fragments.
Today's deployed image emits plain text, so
level:errorfiltering in VictoriaLogs does not work yet — the collector cannot parse the line, keeps the text, and stamps every entrylevel=info. Structured logging is built and tested but requires the image roll andJSON_LOGS=1; see §9.3.
Until then, filter at the source:
kubectl -n tidaldb-cluster logs tidaldb-0 --since=15m | grep -iE 'ERROR|WARN'
7. Live debugging tools work
Proves: you can interrogate a running cluster without hand-rolling curl.
cargo build -p tidalctl # or use a released binary
kubectl -n tidaldb-cluster port-forward svc/tidaldb 9500:9500 >/dev/null 2>&1 &
sleep 9
# --insecure is required: the client port is served with the INTERNAL cluster CA,
# whose leaf is issued for in-cluster DNS names.
./target/debug/tidalctl cluster-status \
--url https://127.0.0.1:9500 --key "$TIDAL_API_KEY" --insecure
echo "exit=$?"
Pass: a leader line, a region table, a shard table. Exit 0 when converged,
2 when not — so tidalctl cluster-status && deploy is a safe gate. Remember
§1.1: NO REPORT means the aggregated view lacks a peer report, not that the
peer is down.
# Convergence monitor, bounded so it terminates.
./target/debug/tidalctl watch --url https://127.0.0.1:9500 \
--key "$TIDAL_API_KEY" --insecure --interval 5 --count 3
Pass: one line per tick, each ending [ok] or [DEGRADED].
Exit-code contract (verified):
| Situation | Exit |
|---|---|
| converged | 0 |
| bad/absent credential | 2 |
| server unreachable | 2 |
--url without a scheme |
1 |
missing --url / --path |
1 |
8. Backups
Proves: a whole-fleet backup completed recently and captured every volume.
# Select the latest backup FROM THE FLEET SCHEDULE. Sorting all backups by
# timestamp picks up restore-canary runs (20 items, 1 volume), which would
# "pass" while telling you nothing about the fleet.
B=$(kubectl -n backup-system get backup.velero.io \
-l velero.io/schedule-name=velero-fleet-daily \
--sort-by=.metadata.creationTimestamp -o jsonpath='{.items[-1].metadata.name}')
echo "checking $B"
kubectl -n backup-system get backup.velero.io "$B" \
-o jsonpath='phase={.status.phase} errors={.status.errors} items={.status.progress.itemsBackedUp}/{.status.progress.totalItems}{"\n"}'
kubectl -n backup-system get podvolumebackups -l velero.io/backup-name="$B" \
--no-headers | awk '{print $2}' | sort | uniq -c
Pass: phase=Completed, no errors, and every PodVolumeBackup
Completed. Observed on velero-fleet-daily-20260823033025: 3708/3708 items, 48/48 Completed.
Careful: a single failed PVB marks the whole backup PartiallyFailed and
freezes the alert gauge, even when every volume that matters was captured. If you
trigger a manual backup to satisfy the alert, it must carry the schedule
label or the metric will not advance:
The alert reads
velero_backup_last_successful_timestamp{schedule="velero-fleet-daily"}, so a
manual Backup must carry that schedule label or the gauge never moves. A
manual run without it completed 48/48 and the alert stayed critical:
metadata:
labels:
velero.io/schedule-name: velero-fleet-daily
9. Operator authority, and what is still inert
The cluster runs
registry.threesix.ai/tidal/server:m12-admin-gate-20260823@sha256:6e220060…
(pods started 2026-08-23 05:32–05:41 UTC). That image carries the
operator/data credential split but predates the observability commit, so
§9.1 and §9.3 below are still inert. They are listed so their absence is not
mistaken for a regression.
9.2 Operator/data credential split — LIVE, verify it stays that way
Confirmed working on this deployment. The admin routes are not published, so port-forward first:
kubectl -n tidaldb-cluster port-forward svc/tidaldb 9500:9500 >/dev/null 2>&1 &
sleep 8
ADMIN=$(kubectl -n tidaldb-cluster get secret tidaldb-credentials \
-o jsonpath='{.data.TIDAL_ADMIN_KEY}' | base64 -d)
# data bearer on an operator verb -> 403 (authenticated, NOT authorized)
curl -sk -o /dev/null -w 'data -> promote %{http_code}\n' -X POST \
-H "Authorization: Bearer $TIDAL_API_KEY" -H 'content-type: application/json' \
-d '{"region":"tidaldb-1"}' https://127.0.0.1:9500/cluster/promote
# admin bearer -> authorized
curl -sk -o /dev/null -w 'admin -> promote %{http_code}\n' -X POST \
-H "Authorization: Bearer $ADMIN" -H 'content-type: application/json' \
-d '{"region":"tidaldb-1"}' https://127.0.0.1:9500/cluster/promote
Pass: 403 then 200. Observed exactly that. Before this key existed the
data bearer could remove members and transfer shards — that is the exposure the
split closes.
The key was hot-loaded with no restart, and the startup log still says it is missing. The pod booted 05:41 and logged
TIDAL_ADMIN_KEY is not set; kubelet materialized the projected secret file at 05:51:43; the credential poller picked it up and the gate went live. So aTIDAL_ADMIN_KEY is not setWARN in the boot log does not mean the gate is open — test the behavior, which is why the two curls above are the actual check.
9.1 HTTP request/error metrics — still inert
PIP=$(kubectl -n tidaldb-cluster get pod tidaldb-0 -o jsonpath='{.status.podIP}')
kubectl -n observability exec deploy/vmagent -- \
sh -c "wget -qO- --timeout=15 http://$PIP:9091/metrics | grep -c tidaldb_http_requests_total"
Currently 0 on all three pods. After the observability image is rolled:
non-zero, and the dashboard's Request rate by route, Requests by status,
5xx ratio, Auth rejections and HTTP p99 panels populate. Until then those
five panels are legitimately empty.
Use
--timeout=15, not 6. A 6-secondwgettruncates this scrape on a busy node and returns zero lines, which reads exactly like "the metric is missing" — it briefly looked like one pod had stopped exporting entirely.
9.3 Structured logs
Add JSON_LOGS=1 to the StatefulSet, then:
kubectl -n tidaldb-cluster logs tidaldb-0 --tail=5
Pass: one JSON object per line carrying ts, level, service, msg, and
request_id inside a request span. level:error then works in VictoriaLogs.
Known-red, not deploy blockers
Verified by bisect against the preceding commit — these are not caused by the observability or credential work:
| Item | State |
|---|---|
mp_follower_reseeds_via_snapshot_after_compaction |
red on this workstation |
mp_quarantined_node_reseeds_without_wipe |
red on this workstation |
mp_multi_group_node_converges_after_reseeding_several_groups |
red on this workstation |
mp_graceful_rolling_restart_under_load_no_reseed |
red on baseline main |
The first three fail on the first ack=quorum write, roughly a second after
the gRPC listeners bind and before peer ship channels are established, against
the harness's own 3s client timeout — a startup race that loses on a loaded
machine. All three fail identically at the commit before this work. The
workstation they were run on is at 100% disk capacity, which is the most likely
aggravating factor. Re-run on a machine with headroom before treating them as a
code defect.
Also open, unrelated to this deploy:
kubectl apply -k k8s/cluster/downgrades live limits (cpu:3/7Giin the cluster vs2/6Giin the manifest). Fix the manifest or apply selectively.- The
tidaldbnamespace standalone Deployment is live1/1while the fleet record calls it superseded. Nothing routes to it.
