…prototype Update .pxl + vis.json column bindings to the schema dx-agent posted on PR #62 (mirror of entlein/dx#68): requestor_pod/responder_pod endpoints, weight (sum of CRS severity) on edgeWeight, max_severity (top single-criterion) on edgeColor, confidence / edge_kind / condition / criteria / num_findings as hover info. Add tools/load_prototype: a Go helper that reads a JSON fixture of []attackgraph.Edge records and executes the script against a Pixie PEM via pxapi. Validates the round-trip and the vispb.Graph column bindings before the dx_attack_graph ingest path lands. Add manifest.yaml so the script enters the script_bundle build. //src/pxl_scripts:script_bundle and :script_bundle_test pass; the script appears in bundle-oss.json. Flagged on PR #62 for follow-up: PxL cannot read forensic_db.dx_attack_graph directly (ClickHouse, not Pixie's table-store). v0 uses a script-arg path; v1 needs a real table ingest (Stirling source connector or AE write-back). Pre-commit arc-lint skipped: arcanist renderer crashes on a PHP null in ArcanistConsoleLintRenderer (unrelated to this change). All individual linters (yamllint/flake8/golangci-lint/JSON) ran clean.

@entlein — dx-agent, thanks. Schema locked, vis bindings locked, MVP scope locked. One bug, one prototype handoff. Answers to your two open questions1) Graph philosophy for v1: attack-path-only — agree. I had stubbed the 2) Column bindings: confirmed. Pushed in commit
One real issue you should know about
Three paths to fix this for v1:
My preference: B2 — your existing AE sink already knows how to write to the Pixie table-store for the OTel adaptive-export path; teaching it a second target is cheaper than a new connector AND doesn't fork the ingest semantics. But it puts the burden on your side. Your call — happy with any of them. Manual-load prototype — readyThe user asked us to ship a manual-load prototype before the ingest path is settled, so the visual + the schema can be validated end-to-end. Pushed in
What I need from you to make the prototype useful: A real fixture — replace Run command, for clarity: go run src/pxl_scripts/px/dx_evidence_graph/tools/load_prototype \
-addr <pem-host>:12345 \
-script src/pxl_scripts/px/dx_evidence_graph/dx_evidence_graph.pxl \
-fixture src/pxl_scripts/px/dx_evidence_graph/fixtures/sample.json \
-investigation_id <one of the ids in your fixture>Bundle status
Pivot hops in v1 — fine. Ping when you have the log4shell fixture ready. |

@ConstanzeTU — bindings + scope confirmed on my side (
Field names == the On the PxL-can't-read-ClickHouse bug — good catch, that's real. I'm taking the ingest decision (B1/B2/B3) to croedig now since it sets AE scope. My lean is B2 for the reason you gave: AE already writes the Pixie table-store for the OTel adaptive-export path, so a second target reuses that machinery and keeps one write semantics — and it's consistent with the "AE owns the write" call we already locked. I'll confirm here once croedig weighs in, then I wire |
|
@ConstanzeTU — scratch B1/B2/B3, the read path already exists. croedig pointed me to the soc repo: this fork's df = px.DataFrame('kubescape_logs',
clickhouse_dsn='forensic_analyst:changeme-analyst@clickhouse-forensic-soc-db.clickhouse.svc.cluster.local:9000/forensic_db',
start_time='-2d')So the architecture is the original simple one: AE writes import px
def dx_attack_graph(investigation_id: str, start_time: str):
df = px.DataFrame('dx_attack_graph',
clickhouse_dsn='forensic_analyst:changeme-analyst@clickhouse-forensic-soc-db.clickhouse.svc.cluster.local:9000/forensic_db',
start_time=start_time)
df = df[df.investigation_id == investigation_id]

@entlein — fixture lands, prototype renders. Pushed in commit `fc2fcc433`. What I had to changeThe pxapi path I'd sketched doesn't work: PxL has no literal-table constructor, so an inline `[]Edge` array can't be fed through `px.DataFrame()` for v0. Until the ingest path lands (B2 / your call with croedig), the manual-load prototype has to render the fixture itself. Pivoted `tools/load_prototype` to a self-contained HTML + cytoscape.js renderer that uses the same column→visual mapping the production `vispb.Graph` spec will use:
Renderings from your fixtureDecoded `log4shell-6a32ea57` — 4 nodes, 4 edges including the cross-pod pivot: ``` `argocd-6a32ea57` — 1 node, 2 stacked self-loops on `repo-server` (execution + collection, w5 each, sev 5). HTML files committed at:
Open them in any browser; no Pixie deploy required. Screenshot incoming separately once @croedig has eyes on it — wanted you to see the data + colour mapping first. Run command (refreshed)```bash One question for youThe `weight=14` pivot edge is interesting — that's wider than any single-criterion edge. Is the per-edge weight intentionally allowed to exceed `max_severity × 5` (i.e. when you sum across multiple findings on the same hop), or should the prototype clamp it to the same heat scale as `max_severity`? My current renderer treats them as independent: thickness from weight, colour from max_severity — works fine on this fixture but I want to know if there's a ceiling I should respect once weights climb into the dozens. Status forward
No work on my side blocked. Ping when croedig signs off on the ingest path. |

@entlein — confirmed and wired. Pushed in commit `8a732065b`. I missed the `clickhouse_dsn` kwarg in my earlier grep — verified now in `src/carnot/planner/objects/dataframe.cc:43` (the `ClickHouseDSN` struct + parser supports `clickhouse://`, `user:password@host:port/database`, bare `host:port`, etc.), with the soc example at `soc/analysis/px_clickhouse/kubescape/observe.pxl` matching exactly what you posted. So scratch B1/B2/B3 — the read path was always there. What's in 8a73206```python The DSN is a `vis.json` script-arg (defaults to the soc `forensic_analyst@clickhouse-forensic-soc-db…` URL) rather than hard-coded, for two reasons:
Operators who never override see exactly your example URL. `script_bundle_test` still passes. What's still needed for prod
Re: weight ceilingIndependent question that's still open from my prior comment — happy to keep the renderer's "thickness from `weight`, colour from `max_severity`" decoupling as-is, but flag any expected ceiling so the UI sizes scale cleanly when fan-in pushes weight into the dozens. No urgency. Re: flipping to ready-for-reviewOnce AE has written any real `dx_attack_graph` row to the soc rig, I can mark this ready and we screenshot from the Pixie UI directly (no `load_prototype` shim).

In `@src/pxl_scripts/px/dx_evidence_graph/dx_evidence_graph.pxl`:
- Around line 58-62: Remove the hardcoded ClickHouse credentials from the
dx_attack_graph function call in the default invocation. Replace the DSN string
parameter that contains the username and password
(forensic_analyst:changeme-analyst) with either an empty string or a placeholder
that does not expose sensitive authentication details. The credentials should be
provided through secure configuration mechanisms like environment variables or
secrets management instead of being hardcoded in the source file.
In `@src/pxl_scripts/px/dx_evidence_graph/README.md`:
- Line 59: The README.md file contains an absolute file system path reference to
/home/constanze/dx-evidence-graph-PLAN.md which is not accessible to other
contributors and makes the documentation non-portable. Replace this absolute
path with a repository-relative reference that other team members can use
regardless of their local directory structure. Use relative path notation (e.g.,
../ or appropriate relative directory traversal) to point to the actual location
of the dx-evidence-graph-PLAN.md file within the repository.
- Around line 19-21: The documentation has a mismatch between the declared
display specification and the actual visualization implementation. In the
Display spec section where edgeColorColumn is documented, change the value from
weight to max_severity on both line 19 and line 104-105 to align with the actual
visualization wiring that uses max_severity for edge coloring. This ensures the
documentation accurately reflects the schema contract for downstream
implementation and testing.
In `@src/pxl_scripts/px/dx_evidence_graph/tools/load_prototype/main.go`:
- Line 156: Locate line 156 in main.go where the HTML root element `<html>` is
being generated and add a `lang` attribute to it (e.g., `lang="en"`). This fixes
the accessibility issue by ensuring the generated HTML document properly
declares its language, which will also apply to all fixture HTML files generated
from this code.
- Line 78: Replace the constant return value "(unknown)" at line 78 and the
similar logic at lines 127-139 with unique identifiers for each unresolved
endpoint. Instead of collapsing all unknown endpoints into a single shared node,
generate a distinct identifier for each one (such as by appending a counter,
hash, or UUID to create uniqueness), ensuring that unrelated unresolved
endpoints remain as separate graph nodes and prevent false edge creation.
- Around line 220-231: The edge event handler in the tap listener is
concatenating user data directly into innerHTML, creating an XSS vulnerability.
Instead of building an HTML string and assigning it to detail.innerHTML, use DOM
manipulation methods to safely construct the element. For each data field (id,
edge_kind, condition, criteria, weight, max_severity, confidence, num_findings,
source, target), create div elements using createElement, set the label using
textContent, and append the value using textContent (not innerHTML) to ensure
data is treated as text rather than executable markup. This prevents malicious
scripts or markup in the data from being executed while displaying the edge
information safely.
In `@src/pxl_scripts/px/dx_evidence_graph/vis.json`:
- Around line 16-20: Remove the credential-bearing DSN from the defaultValue
field of the clickhouse_dsn parameter in the vis.json file. Replace the current
defaultValue that contains the username, password, and full connection string
with an empty string or a non-sensitive placeholder like a generic format
example. Credentials must be provided at runtime by the user rather than being
hardcoded in the script's default configuration.

Seven findings, all fixed: 1+7) Drop the credentialed default DSN from both dx_evidence_graph.pxl and vis.json. Default is now empty; operators paste the per-rig DSN via the UI script-args panel. README documents the soc rig DSN as the canonical example, not the bundle ship value. 2) README claimed edgeColorColumn=weight; vis.json uses max_severity. Rewrote the README end-to-end (it was still the stub-PR coordination contract from before dx-agent locked the schema — stale on multiple axes) to match the shipped script. 3) Replaced /home/constanze/... absolute path in README with the relevant repo paths. 4) load_prototype's endpointID collapsed every unresolved endpoint to a single "(unknown)" node, silently merging distinct hops. Tail with side + edge-index so unresolved endpoints stay distinct: "(unknown-src-3)", "(unknown-dst-3)". 5) <html lang="en"> added. 6) Detail panel built innerHTML by string concat over Edge fields, so any markup in condition/criteria/edge_kind would parse as HTML. Switched to DOM APIs (createElement + textContent + appendChild) — values land as text, not parsed HTML. Same render, no XSS surface. Regenerated fixtures/screenshots/ HTMLs from the cleaned renderer. //src/pxl_scripts:script_bundle_test still passes.

@coderabbitai — all 7 findings addressed in commit `44424802e`. Brief mapping:
Regenerated `fixtures/screenshots/dx_log4shell.html` + `dx_argocd.html` from the cleaned renderer. `//src/pxl_scripts:script_bundle_test` still passes locally. DSN-as-empty-default has one operator-visible side effect: running the script for the first time on a new cluster errors at `px.DataFrame(clickhouse_dsn='')`. The error message from the parser is informative enough (`empty DSN`); the README is the place that surfaces the per-rig URL. If anyone has a stronger preference I'm open to either (a) restoring a host-only default with no credentials, or (b) wrapping the call to emit a more script-friendly error. |
|
On the empty-DSN UX question: I'd lean toward (b) — a guard in the PxL script rather than restoring a host-only default. A host-only default still bakes an assumption about the cluster topology into the bundle; an explicit guard keeps the bundle neutral and surfaces a human-readable message immediately. Something like: def dx_attack_graph(start_time, investigation_id, clickhouse_dsn):
if clickhouse_dsn == '':
px.display(px.DataFrame.__doc__) # or raise a labeled error

… in the UI Two corrections from dx-agent on PR #62 (verified against src/pxl_scripts/px/net_flow_graph/vis.json, the shipping reference for vispb.Graph widgets): 1) vis.json: replace the inline "func" block with a top-level globalFuncs entry + globalFuncOutputName on each widget. The inline form fails with "func not found" at UI render time. The shape now mirrors net_flow_graph exactly — globalFuncs.outputName = "dx_graph", widgets reference globalFuncOutputName: "dx_graph". 2) dx_evidence_graph.pxl: drop the `if investigation_id != ''` — PxL has no `if` statement. Signature is now the 2-arg shape (start_time, clickhouse_dsn) that matches the globalFuncs args. Per-investigation filtering is a follow-up (Pixie's convention for optional filters is to omit them rather than gate at script level; matches how net_flow_graph handles its namespace arg). Adds a second widget binding the same globalFunc output to a vispb.Table — the dx_attack_graph data is small (single-digit edges per investigation), so a flat table view next to the graph is a free win for the operator. //src/pxl_scripts:script_bundle and :script_bundle_test pass. Bundle includes the corrected entry: globalFuncs:[(dx_graph, dx_attack_graph)], widgets: [dx_graph, dx_graph].

The Graph widget keyed on *_pod alone, so EVERY such edge collapsed into one bogus "" node — visually merging unrelated peers (the API server, every distinct remote IP) into one. Coalesce node identity to pod, else service, else IP (the same idiom net_flow_graph uses: px.select(src=='', src_ip, src)) and point the adjacencyList from/to at the coalesced columns. Now each distinct peer is its own node. Validated live (px run, forensic_db): control-plane → k8s-apiserver; the 5 consulted sockets → 5 distinct IPs (10.43.143.34, 10.42.0.1, ::1, 127.0.0.1, 10.42.0.43) instead of one merged node.

* adaptive_export: production AE — streaming export + write-integrity
Signed-off-by: entlein <einentlein@gmail.com>
* adaptive_export: ADAPTIVE_PASSTHROUGH firehose loop
New env-gated background loop that runs the same PxL shape AE's
anomaly-gated path uses, but with an empty Target (no ns/pod predicate)
and over a configurable rolling window. Writes via the existing sink so
the byte-shape of forensic_db rows is comparable between the
PASSTHROUGH=1 phase (EVERYTHING) and the PASSTHROUGH=0 phase
(AE-FILTER). One-shot A/B that yields the per-table capture fraction of
the adaptive write path.
- internal/passthrough/passthrough.go — Loop + Config; defaults to
30s window / 30s refresh / clickhouse.PixieTables() table list.
- internal/passthrough/passthrough_test.go — 6 tests; the load-bearing
one is TestLoop_EmitsEmptyTargetPxL (asserts neither df.namespace nor
df.pod predicates appear in the emitted PxL).
- cmd/main.go: ADAPTIVE_PASSTHROUGH + _WINDOW_SEC + _REFRESH_SEC env
knobs. Adapter is constructed unconditionally when passthrough is on
(joins the existing PushPixie / streaming construction path so the
same pxapi grpc stream is reused). Loop is registered with the
shutdown WaitGroup so SIGTERM waits for the in-flight tick.
- cmd/BUILD.bazel: drop @px// load (other AE BUILD.bazel files use
//bazel — sticking out as the only one with @px is a leftover from a
prior gazelle run; align). Add passthrough dep.

* ci: dx-image workflow — build + publish dx-daemon to ghcr
Stand-alone workflow that builds entlein/dx (private Active-Diagnosis
Framework) into ghcr.io/k8sstormcenter/dx-daemon. Separates the dx image
publish from the bazel-based vizier_release pipeline; the dx repo ships
its own Dockerfile.dxd (Go cross-compile + distroless final stage) so it
doesn't need to live as a submodule inside src/vizier/services/dx.
Triggers:
- tag push 'release/dx/v*' on this repo cuts a release build, image tag
derived from the tag suffix (release/dx/v0.1.0 -> image tag 0.1.0).
- workflow_dispatch lets us build any dx ref on demand with a custom tag
(default: short sha of the resolved dx commit).
Pulls dx via DX_ENTLEIN_PAT (already configured on the repo). Multi-arch
build (linux/amd64, linux/arm64); Dockerfile.dxd cross-compiles in the
native BUILDPLATFORM stage and the final stage is COPY-only, so target
emulation isn't required.

* Revert ci: dx-image workflow — wrong repo
The dx image build pipeline lives in entlein/dx itself (PR #53,
branch feat/bazel-release): bazel-based with @px external pin to
pixie's ae-prod tip, pushes to docker.io/entlein/dx-daemon on a
release/dx/v* tag in the dx repo. The pixie-side buildx workflow
this reverts duplicated that intent in the wrong repo + the wrong
build system (docker buildx instead of bazel + pl_go_image macros)
+ the wrong registry (ghcr.io/k8sstormcenter instead of
docker.io/entlein).

* adaptive_export: unit-normalize trigger watermark cursor + load-test affordances
Fixes the silent-halt bug: the trigger gated on a RAW event_time high-water-mark,
so a single anomaly in a larger unit (ms/ns) drove the watermark past all real
seconds rows and AE stopped processing forever (data still on Pixie). Normalize
event_time to canonical nanoseconds in the poll SELECT filter+order and in the
in-memory/persisted cursor, boundary-dedup, and maxSeen (normalizeEventTimeNanos
+ chNormEventTimeNanos). Validated at the data layer: vs a poisoned watermark the
raw filter returns 0 rows, the normalized filter recovers all 60.
Also adds ADAPTIVE_PUSH_REFRESH_SEC (negative = single-shot pull) for the
reproducible load-test harness, an in-package trigger unit test, and an e2e
hermetic load test (mock PixieQuerier, exact rows+bytes).

* e2e_test/adaptive_export_loadtest: AE fixture-isolation load-test harness
Consolidate the adaptive_export load-test harness under src/e2e_test/ (matching
vzconn_loadtest / px_cluster conventions). Control-plane experiments (E1-E4, E6,
E8 sustained) are proven exactly-reproducible on a live rig; the data-plane
experiments (E5, E8 data-mode) are authored and pending live validation on a
vizier-registered rig (status documented in README + FINDINGS_AND_BACKLOG).
- harness/: shell + python (inject, exp_control, exp_e8, stats, ...) + lib helpers
- fixtures/EXPERIMENTS.md: curated kubescape_logs data-set catalog + expected outputs
- k8s/: isolated sinks + per-rep generator pod (no probes)
- tools/loadgen/: cleanloadgen + httpsink (docker-built test tool; .bazelignore'd
pending a bazel target — lib/pq is already vendored in the module)

* adaptive_export/trigger: update test SQL substrings for multiIf normalisation
The 700821d3b trigger unit-normalisation wrapped event_time in a
multiIf(...) inside both the WHERE filter and the ORDER BY. Three
existing tests in watermark_test.go + one in clickhouse_test.go pinned
the raw 'event_time >= N' substring and broke at HEAD.
Update each test's expected substring to match the new normalized form
(') >= <ns-scaled N>' — the closing paren of multiIf, then the value
in canonical nanoseconds). Per-test ns-scaling:
watermark_test.go:94 1744000000000000000 already ns -> unchanged

* adaptive_export: ADAPTIVE_RECONCILE per-pull write-fidelity instrument
Records one forensic_db.ae_reconcile row per data-plane pull (read_count vs
wrote_count, window, ns/pod) across ALL three write paths — controller fan-out
(filter), passthrough firehose, and streaming scanner — so a reconcile run
localizes loss to query (R5: read<PEM) vs sink (R6: wrote<read) and quantifies
re-pull dup (C8). Counts alone (write >= read) were proven insufficient.
- new internal/reconcile leaf package (Row, Recorder, Nop) — no import cycle
- sink.Record: CH-backed recorder (INSERT INTO forensic_db.ae_reconcile)
- ae_reconcile table: schema.sql + KnownTables + OperatorOwnedTables (synced);
not a pixie table (absent from PixieTables, so VerifyPixieSchema ignores it)
- wired: passthrough.tick, controller.pushPixieRows (deferred, all return
paths), streaming.scanner.Run; gated by ADAPTIVE_RECONCILE=true, else Nop
- unit test proves read/wrote capture incl. the sink-drop read>wrote shape
- fixed apply_test trailing-tables guard for the new operator table

* adaptive_export(passthrough): precompiled + concurrent firehose, drop http2
- pxl.CompilePassthrough/Render: precompile per-table PxL once (fixed
window => constant relative start_time), only the two time_ bounds are
stamped per tick. Rendered output is byte-identical to QueryFor with an
empty Target (TestCompilePassthrough_MatchesQueryFor), so this is a
structural change, not a capture change. upid->pod/ns stays in PxL.
- passthrough: tickConcurrent fans every table out at once (was a serial
loop); shared pull() helper. Sink/recorder are pool/HTTP-backed and
already called concurrently elsewhere.
- drop http2_messages.beta from the firehose set (not materialised on
every cluster => ""Table not found"" every tick); shared PixieTables/DDL

* adaptive_export(pxl): raise Pixie 10k result cap via #px:set query flag
F1 RCA: Pixie caps every px.display at max_output_rows_per_table (default
10000, query_flags.go) — the planner add_limit_to_batch_result_sink_rule
silently truncates wide firehose windows / busy pods at the READ (write path
is clean: ae_reconcile shows read==wrote). Fix uses Pixie own native knob —
prepend `#px:set max_output_rows_per_table=1000000` to every generated PxL
(QueryFor + CompilePassthrough) so all pull paths are uncapped. Validated on
rig: a 14208-row window returned 10000 (capped) vs 14298 (with flag). No
pagination loop, no extra round-trips. See memory project-ae-passthrough-10k-cap.

* adaptive_export_loadtest: DX-steered-vs-ALL datavolume reduction harness
Measures the AdaptiveExport value prop: datavolume REDUCTION of DX-steered AE
(rev-3 streaming, AE writes only DX-steered activeSet pods over the control
surface) vs saving ALL data (passthrough firehose). Two arms, same fixed load,
forensic_db active-part deltas (rows+bytes) per table; reduction = 1 - DX/ALL.
Uses the canonical resolvable JNDI FQDN (attacker.attacker-ns.svc.cluster.local)
so the chain fires + DX can classify (a malformed host → NXDOMAIN → no steer).
Successor to ae_vs_all.sh, whose AE arm used the rev-2 controller gate + stale JNDI.

* adaptive_export_loadtest: deep AE NFR benchmark harness
Measures all AE non-functional requirements under steady load on the rig:
throughput (rows+bytes/sec), capture completeness (AE read vs broker count =
F1 cap proof), write fidelity (read==wrote + write-error count), end-to-end
freshness latency (now - max(time_) in CH), resource footprint (AE pod cpu/mem
idle vs loaded), per-cycle cadence. Emits a structured report; companion to

* adaptive_export_loadtest: fix DX-reduction dead-arm (clear stale steering + live-pod guard)
Run-1 reported false 100% reduction because stale adaptive_attribution windows
rehydrated DEAD pods (deleted loaders) into the activeSet → AE streamed dead pods
→ 0 rows. Clear adaptive_attribution before the DX arm so the activeSet only gets
freshly-steered LIVE pods; add a guard that prints the steered pods + marshalsec
fire count + live log4j-poc pods so a dead-arm result is caught, not reported as
a reduction.

Eviction-RCA finding (PR #63 NFR campaign): AE had NO memory limit (only cpu
300m) and was CPU-pinned at 300m under concurrent passthrough. AE measured tiny
(16-38Mi steady), but the raised 1M-row passthrough cap can spike, so cap at 1Gi
so AE can never memory-pressure a node; raise cpu limit 300m->1 core (was
throttling). NOTE node evictions were NOT AE/OOM — node-01 went NotReady
(network/heartbeat); the memory consumer is PEM (1365Mi, OOMs at the 2Gi default).

* ae bootstrap: separate the secret from the re-applied infra bundle
Root cause of the recurring "AE unauthenticated / writes 0 / crashloop" reverts:
kustomization.yaml bundled adaptive_export_secrets.yaml (placeholder pixie-api-key)
with the role+deployment, so EVERY infra re-apply (make log4j) clobbered the real
key that ae-auth had written. Separation of concerns: remove the secret from the
kustomization — infra (role+deployment) stays re-appliable; the secret holds real
creds and is owned solely by `make ae-auth`, created once, never touched by infra
re-applies. Secret manifest kept as a hand-applied seed-only template (documented).

* dx-reduction harness: fire BOTH attack stages so DX steers the backend
The DX-steered arm was failing because the harness only fired stage-1 (JNDI/LDAP).
That generates ldap-egress but NO kubescape R0001 → backend never flagged → DX no
case → indeterminate → AE steers wrong/no pods. R0001 comes from stage-2 (post-
exploitation exec). fire() now does stage-1 (JNDI) + stage-2 (whoami/shadow/token/
getent in the backend) → kubescape R0001+R0006 → DX rules backend MALIGNANT →
backend enters AE activeSet → reduction is measurable. Verified live: DX evidence
unexpected-spawn+sensitive-file-read → verdict ruled_in generic=MALIGNANT.

* adaptive_export: rename whitelist→allowlist across streaming path + add DX-steering diagnostics
Standing terminology rule: allowlist/blocklist, never whitelist/blacklist.
Pure rename (no behavior change) of the rev-3 streaming filter:
FilterModeWhitelist → FilterModeAllowlist
MaxWhitelistSize → MaxAllowlistSize
ADAPTIVE_STREAM_MAX_WHITELIST → ADAPTIVE_STREAM_MAX_ALLOWLIST (env)
mode=whitelist log string → mode=allowlist
plus all comments/identifiers/tests in streaming, activeset, cmd/main.
DX-steering diagnostics (the reason DX-arm-writes-0 has been hard to RCA —
we could not tell "empty ActiveSet" from "broker returned 0 rows"):
- scanner: log the empty-allowlist short-circuit (was silent) so an
empty ActiveSet is visible in logs, distinct from "query completed rows=0".
- FilterUpdater: emitted-filter log Debug→Info so the steered pod count
per ActiveSet change is visible without debug logging.
NOTE: ADAPTIVE_STREAM_MAX_WHITELIST env renamed → tooling that sets the old
name must switch to ADAPTIVE_STREAM_MAX_ALLOWLIST.

* ae(clickhouse): create forensic_db.dx_attack_graph at boot
The Pixie dx_evidence_graph UI reads dx_attack_graph via px.DataFrame
clickhouse_dsn, whose query template hardcodes event_time + hostname and
ORDER BY event_time. A table without those columns fails 'Unknown
identifier event_time'; a table created by hand (local, not via the
operator) isn't globally registered. Fix: make AE own it like the other
forensic tables.
- schema.sql: dx_attack_graph DDL with event_time(UInt64 nanos) + hostname,
edge columns, fromUnixTimestamp64Nano partition/TTL (nanos-correct).
- KnownTables + OperatorOwnedTables: register it so Apply creates it at boot.
- apply_test: assert last-applied DDL == last OperatorOwnedTables entry
(robust to appended operator tables) instead of hardcoding trigger_watermark.

* adaptive_export(streaming): add #px:set max_output_rows cap flag to scanner buildPxL
The DX/streaming arm silently capped each per-table pull at Pixie's default

QueryFor) already raises it to 1,000,000 via the broker's #px:set query flag.
Validated live on 6a33dac0: a single streaming http_events pull returned
exactly rows=10000 (the cap). Left unfixed this UNDER-counts the DX arm and
OVERSTATES the DX-vs-ALL volume reduction. Prepend the same #px:set directive
to the streaming scanner's PxL so both arms are uncapped and comparable.

* adaptive_export: convention pass — consolidate CH HTTP, drop dead code, fix stale tests
PR-53 review follow-ups (see review summary in conversation):
1. License headers added to 17 src/e2e_test/adaptive_export_loadtest/
harness/*.{sh,py} scripts. Matches the convention every other
src/e2e_test/*/sh in pixie already follows.
2. Dead code removed (was unreachable per golang.org/x/tools/cmd/deadcode):
- internal/script/script.go: IsClickHouseScript, IsScriptForCluster,
GetActions, getScriptName, getInterval, templateScript, plus the
ScriptConfig and ScriptActions types. The cron-script sync flow they
served was replaced by the streaming model; only the Script and
ScriptDefinition types remain.
- internal/pixie/pixie.go: Client.GetPresetScripts (replaced by
builtinPresetScripts() inline in cmd/main.go).
- internal/streaming/{supervisor,writer}.go: SupervisorStats,
TableStats, Stats types + Supervisor.Stats and BatchWriter.Stats
methods (no production reader). Atomic counters dropped; the
existing flush log preserves the per-flush summary.
3. Stale passthrough tests fixed.
TestLoop_DefaultsTablesToPixieTables and TestNew_AppliesDefaults
asserted len(clickhouse.PixieTables()) == 13 but passthrough.New
strips excludedTables (http2_messages.beta), yielding 12. Tests now
compare against filterExcluded(clickhouse.PixieTables()) and add an
extra assertion that excluded tables were not written.
4. ClickHouse HTTP client consolidation: new internal/chhttp/ package
collapses three near-identical HTTP CH clients
(clickhouse.Applier, sink.ClickHouseHTTP, trigger.ClickHouseWatermarkStore)
into one. Centralises endpoint validation, basic-auth header,
30s default timeout, fail-loud INSERT settings (4 CH input_format
knobs), and the X-ClickHouse-Summary read path. The 4 INSERT
call sites in the three callers all route through chhttp.Client.Insert
now; SELECT through Query or QueryStream (the latter preserves the
QueryActive streaming behaviour). Net code: -200 LOC across the
three callers plus a 200-LOC chhttp package with its own tests.
5. Pixie service scaffold wired into cmd/main.go:
services.SetupService("adaptive-export", 50900) +
services.SetupSSLClientFlags() + services.PostFlagSetupAndParse() +
services.SetupServiceLogging(). Matches the pattern every other
pixie Go service uses. CheckServiceFlags() is deliberately skipped
(AE does not run a TLS gRPC server). Existing AE env-var reads
(ADAPTIVE_*) are untouched and still authoritative for tuning knobs.
All 14 adaptive_export internal packages pass go test (1 new chhttp,
13 unchanged), including the 3 differential oracle tests in
pxl/compile_test.go. arc lint OKAY for everything except 3 pre-existing
findings unrelated to this commit (loadgen has its own go.mod; one
QF1001 De Morgan's-law nit in reconcile_test.go from c9f19b6b1).

on the conn_stats sink-drop assertion.
- script/script.go: rename ScriptId -> ScriptID (ST1003). Propagated

- internal/e2e/BUILD.bazel and internal/trigger/BUILD.bazel: gazelle
drift — adding loadtest_test.go and clickhouse_internal_test.go to
srcs.
- k8s/00-sinks.yaml + gen-pod.tmpl.yaml: yamllint compliance —
document-start marker, dedent sequence items per .yamllint
indent-sequences=false, tighten flow-mapping spaces, collapse
multi-space after commas. YAML semantics unchanged.

whose auth interceptor accepts pixie-api-key and rejects JWT service
tokens (those are for INSIDE-cluster vizier services). The
pixieapi.Adapter that talks to vizier directly already uses JWT via
jwtutils.GenerateJWTForService — same pattern as
cloud_connector/vizhealth/checker.go:111. So the split is intentional;
flipping pixie.go to JWT would break cloud auth, not improve it.
#6 pxl/queryfor — hardened escapePxL so a raw \n, \r, \t or NUL byte
in Target.Pod/Target.Namespace can't terminate the PxL string literal
and inject a new statement. Added TestQueryFor_RejectsInjectionInTargetFields
driving QueryFor with 7 adversarial pod/namespace shapes (newline,
single-quote-only, CR, backslash-escape-of-escape, NUL, tab) plus
the regex_match fallback path, asserting the output line count and
every statement's leading token. Extends existing
TestEscapePxL_TableDriven with the new escape mappings.
CodeRabbit oversights (verified each against current code):
CR r3379377432 (main.go) — wrapped the control-surface listener in
http.Server with Read/ReadHeader/Write/Idle timeouts so a slow
client can't pin a goroutine indefinitely.
CR r3379377607 (pixieapi.go) — switched direct-mode dial from
pxapi.WithDisableTLSVerification (env + addr-gated, brittle) to
pxapi.WithDirectTLSSkipVerify (added in PR #49 b523ce362 for the
same node-IP-dial scenario). Removed the cluster.local + PX_DISABLE_TLS
precondition in NewDirect; the always-skip semantics match the AE
deployment shape. Refactored the obsolete env-gate test.
CR r3379377645 (streaming/filter.go) — the deltaCh-close path returned
without calling disarm(), leaking the timer's goroutine on shutdown.
Now calls disarm() before return on chan-close.
CR r3426923299 (sink/clickhouse.go Record) — capped Record at a 2s
per-call context timeout. The 30s chhttp default was too long for
the scanner/passthrough/controller hot paths that call Record inline;
reconcile is best-effort by contract, so a stalled CH must not pin
the pull loop.

* test(harness): consolidate to one run-picture + e2e CI workflow
Finish the harness consolidation #53 started: adopt exp_matrix.sh (canonical
ALL-vs-DX reduction matrix) + nfr.sh (throughput/mem/verdict-latency) as the
single runners; cut the overlapping variants (ae_vs_all, exp_datavolume_extreme,
exp_dx_steering_reduction, exp_ae_nfr_benchmark, exp_pipeline_reconcile) and the
superseded standalone setup (deploy_ae, build_gen_image). README rewritten as the
single 'how to run' source: two families — fixture-isolation (run.sh + E-series)
and live-attack e2e (log4shell_fire → exp_matrix → nfr → exp_row_reconcile).
Add e2e_log4shell_soc.yaml: k3s + full SOC stack (Pixie/kubescape/ClickHouse/AE/dx
via k8sstormcenter/soc) on the oracle runner; asserts every canonical harness
script runs + dx rules in; profiles dx in real life (pprof CPU/heap + verdict
latency, uploaded). Uses existing repo secrets.

* revert(bazel): drop stray buildifier attribute-reorder in stirling container_images BUILD
This file is unrelated to adaptive_export — the only change was buildifier
alphabetizing container_type/bazel_sdk_versions (no functional change). Restore
main's version to keep #53's diff to real AE changes.

* ci: fix run-genfiles + run-container-lint on PR 53
run-genfiles: the PR had reordered the kwargs in stirling/.../container_images/
BUILD.bazel alphabetically (bazel_sdk_versions before container_type) — a
local buildifier or gazelle drift from when the file was first committed.
CI gazelle wants the original order (container_type first), so the diff
loop fails. Restored to origin/main's ordering. Local gazelle disagrees
with CI's expected output (tooling-version drift); CI is authoritative.
run-container-lint: two findings.
1. staticcheck QF1001 (De Morgan's law) in
pxl/queryfor_test.go:318. Rewrote the !(a || b || c || d) negated
disjunction as the equivalent !a && !b && !c && !d. Test behaviour
unchanged; verified locally with TestQueryFor_RejectsInjection.
2. golangci-lint typechecking failed on
src/e2e_test/adaptive_export_loadtest/tools/loadgen/cmd/{cleanloadgen,
httpsink}/main.go because that subtree carries its own go.mod and
does not resolve as a package under the root px.dev/pixie module.
Added the loadgen subtree to .arclint's exclude list. Same fix the
existing entries for other-module subtrees apply.

* ci: apply gazelle's actual kwarg order to stirling container_images
run-genfiles CI re-failed after f244ffc6c reverted this file to main's
ordering — turns out gazelle on this repo IS alphabetizing the kwargs
(bazel_sdk_versions before container_type), and CI runs 'gazelle fix'
then 'git diff' to catch any drift. So main's ordering is no longer
gazelle-stable; the file has to match gazelle's preference, not main's.
Verified locally with 'bazel run //:gazelle -- fix'; the file is now
idempotent (a second gazelle run produces no diff).

Dedented every step item + its run: block by 2 spaces.

* feat(ae-control): bearer-JWT auth + input validation (CodeRabbit followup)
AE control endpoints had no auth. Add it using the SAME shared lib the vizier
broker/PEM use (px.dev/pixie/src/shared/services/utils): SetAuth verifies a
bearer JWT via jwtutils.ParseToken (signature + audience), middleware on
Handler() with /healthz exempt. dx already mints this exact service JWT
(GenerateJWTForService, PL_JWT_SIGNING_KEY) — it just attaches it. No new
secret/crypto. Flag-gated (CONTROL_REQUIRE_AUTH + PL_JWT_SIGNING_KEY), default
OFF so it merges before dx sends the bearer; flip on after dx is updated.
Also: reject invalid t_end (<=0) and query windows (start>=end, non-positive).
Test mints a real JWT via the shared lib; asserts 401 on missing/bad token,
pass on valid, /healthz open.
* fix(ae): remaining CodeRabbit Majors (#53 followup)
- controller: don't fan out Pixie rows when attribution Sink.Write fails
(avoids orphaned rows; release in-flight slot, non-fatal). (controller.go:347)
- controller.Rehydrate: re-arm rev-1 pushPixieRows for restored windows so a
restart doesn't silently miss post-restart Pixie data. (controller.go:255)
- passthrough.pull: per-table timeout context so a hung dependency can't stall
the sweep / delay shutdown (covers serial+concurrent ticks). (passthrough.go:147)
- schema: TTL (30d) on ae_reconcile to cap append-only growth. (schema.sql:485)
Verified no-change-needed: adaptive_attribution ORDER BY (hostname, anomaly_hash)
is safe — anomaly_hash already encodes namespace+pod (anomaly/hash.go), so rows
never collapse across ns/pod. (schema.sql:430)
Already on ae-prod (no-op): filter timer leak, stats.py EXACT guard, sink async,
watermark paging, pixieapi WithDirectTLSSkipVerify, http.Server timeouts.
* fix(ae-trigger): escape a PollLimit-saturated watermark boundary (from #67)
ae-prod's boundary handling accumulates the seen-fingerprint set on a no-progress
tick, but if >PollLimit rows share one normalized event_time the SQL
(>= watermark ORDER BY time LIMIT N, no secondary key) returns the same N boundary
rows every poll → rows beyond N at that timestamp are never emitted (infinite
boundary). Detect all-skipped-at-capacity and advance the watermark by 1ns to make
forward progress (fingerprint dedup already tolerates the 1ns overlap).
Cherry-picked the trigger fix + its test from the stale CodeRabbit-chat PR #67
(687851d8c); dropped that PR's unrelated gen-pod.tmpl.yaml churn. #67 itself is
NOT mergeable (77 commits behind ae-prod, re-adds deleted terraform).
* feat(ae-control): TLS on the control surface (CONTROL_TLS) (#71)
Auth without TLS is half a control: tcpdump on dx→AE :9100 captured 720
cleartext `Authorization: Bearer` JWTs in 70s — the #68 token crosses the
CNI in plaintext. CONTROL_TLS=true now serves TLS with server.crt/key from
the service-tls-certs secret (broker/PEM already use it; dx skip-verifies).
Default-OFF for incremental rollout, symmetric to CONTROL_REQUIRE_AUTH.
Stacks on #68 (ae-followup-auth). dx client half: entlein/dx#88.

* test(ae-trigger): differential oracle vs naive reference (incremental → 73.7% cov)
The trigger's incremental kubescape-events pump has 3 moving parts
that must agree: watermark advancement, boundary fingerprint dedup,
and PollLimit-saturated draining (PR #67 fix). Existing tests cover
each in isolation. This new file pins them TOGETHER against the
simplest possible reference ("drain everything in event_time order,
dedupe by fingerprint, advance the cursor to max(event_time)"). If
the iterative trigger and the reference disagree on the set of
emitted rows for ANY poll sequence, one of the three parts is wrong.
Four oracle tests:
TestOracle_TriggerEmitsNaiveSet_StaggeredCorpus — 50 rows scattered
across distinct event_times, PollLimit=10 forces ≥5 polls; trigger
must emit exactly the 50 rows the naive reference computes.
TestOracle_PollLimitSaturation_AtCapacity — regression guard for PR
#67 (dfdc465a9): when EXACTLY PollLimit rows share a boundary
event_time, every one of them must emit, and the cursor must clear
the boundary for the next-event_time row that follows.
TestOracle_PollLimitOverflow_DocumentsLossBound — pins PR #67's
intentional trade-off: when >PollLimit rows share a boundary
event_time, the first PollLimit emit, then the 1ns escape advances
the cursor past the surplus. Lock-in test: if a future fix recovers
the surplus (good!) this test fails loudly so both can update in
lock-step instead of regressing silently.
TestOracle_BoundaryDedup_NoDuplicates — when CH returns the same
boundary row in two consecutive polls (real production case: a new
row lands at the same event_time after a previous poll's cursor
advanced past it), the seenAtBoundary map must filter the duplicate.
Coverage: trigger 71.6% → 73.7% (statement-level). The oracle's value
isn't in statement count — it's in property-level coverage on
invariants the per-feature tests can't enforce together.
Build.bazel: adds oracle_test.go to the existing trigger_test target.
* ci: fix vizier-release Build Release runner label (oracle-16cpu → oracle-vm-16cpu)
Merge from main re-introduced the deprecated 'oracle-16cpu-64gb-x86-64'
label on the Build Release job. That label doesn't resolve in the
fork's runner pool, so aeprod22's release workflow sat queued
indefinitely. update-gh-artifacts-manifest at L143 already had the
'-vm-' variant; align Build Release at L18 to match. Same fix the
fork applied earlier in 21d536e3d for the standalone vizier_release
workflow — main keeps regressing it.
* ci: fix merge-conflict regressions from main pickup (runner labels, ui.bzl, fork cockpit)
The merge of main into ae-followup-auth (0c657514a) silently took the
upstream version on a swath of files where the fork had previously
deviated. This commit reverts the merge's regressions back to the
fork-correct state (origin/ae-prod) AND completes the runner-label
sweep so every release/mirror/perf workflow uses the same -vm-16cpu
label the fork's runner pool actually has.
1. Runner labels — main re-introduced 'oracle-16cpu-64gb-x86-64' and
'oracle-8cpu-32gb-x86-64' on 7 workflows. Fork's pool only resolves
'oracle-vm-16cpu-64gb-x86-64'; both stale labels sit queued forever.
Fixed: cli_release.yaml (L18+L212), cloud_release.yaml (L18),
mirror_demos.yaml (L12), mirror_deps.yaml (L12),
mirror_releases.yaml (L13), operator_release.yaml (L18+L143),
perf_common.yaml (L37+L60). vizier_release.yaml L18 was fixed
already in 0fd9c3f21.
2. bazel/ui.bzl — main reverted PR #64's webpack-build fixes that
broke release/cloud/v0.0.10 with 'export: `18': not a valid
identifier'. Restored: 'set -x' for action-shell tracing, PATH
that puts /opt/px_dev/tools/node/bin FIRST, 'hash -r', the
STABLE_BUILD_TAG|BUILD_TIMESTAMP allowlist sed (vs the wildcard
that word-splits FORMATTED_DATE), and use_default_shell_env=True
so --incompatible_strict_action_env doesn't strip yarn from PATH.
3. 28 fork-cloud config files — main's PR #2391 (cert-manager
migration) deleted private/cockpit/*,
terraform/kubernetes/auth0/*, terraform/kubernetes/cloud_deps/*,
.sops.yaml, private/skaffold_cloud.yaml. These are still load-
bearing for the AOCC pixie-cloud deployment; the fork hasn't
migrated to cert-manager-compatible secrets yet (PR #2391's
monitor.go fallback path is in place, so adoption is the
follow-up, not a blocker). Restored all 28 from origin/ae-prod.
Genuine main pickups that were CORRECT to keep (no fix needed): the
src/utils/shared/k8s/{apply,delete}.go import-order +
sets.New[string] generics migration,
src/operator/controllers/monitor.go's cert-manager secret fallback,
and the src/carnot/BUILD.bazel + src/carnot/exec/BUILD.bazel
additions.
* fix(ae): address 13 CodeRabbit Go-code findings on PR 68
11 TRUE + 2 PARTIAL CodeRabbit comments verified against current code;
all valid. This commit lands every one of them as a discrete change,
keeps the existing tests green, adds new tests where the contract
itself changed.
🔴 Real bugs:
controller/controller.go: handle() now SNAPSHOTS c.active[hash]
before mutation and ROLLS BACK on sink.Write failure. Without
this, a failed persist left c.active extended; an already-running
pushPixieRows would re-snapshot and fan out data based on an
attribution row that never landed in CH. Updated
TestController_SinkErrorNonFatal to pin the new rollback contract
(active==0 after sink error) and added a writeAttempts() observer
on fakeSink so the test doesn't race.
sink/fastencode.go: appendJSONValue now rejects NaN/+Inf/-Inf
floats with errFastEncodeUnsupported (triggers the encoding/json
fallback). Previously strconv.AppendFloat emitted invalid JSON
tokens that made CH reject the whole batch.
streaming/writer.go: flush() keeps the row buffer on write failure
(so the next attempt retries instead of silently dropping), and
the shutdown branch uses context.Background() for the final flush
so it isn't fast-failed by the already-cancelled parent ctx.
control/server.go: decode() now wraps the body in
http.MaxBytesReader(w, body, 4 MiB) so an oversized JSON payload
on the public(-ish) control endpoint can't OOM the operator. The
JWT auth still gates access — this hardens what a holding-an-
acceptable-JWT attacker can do.
🟠 Lower-impact:
cmd/main.go: isOperatorManagedScript matches the EXACT builtin
names (no "ch-" prefix), so a user-authored script named
"ch-something-custom" can't get deleted under
INSTALL_PRESET_SCRIPTS=true.
chhttp/chhttp.go: QueryStream now uses a separate http.Client with
no Timeout. Go's http.Client.Timeout covers body reads, so
reusing the 30s default would silently truncate a multi-MB
active-set rehydrate. Stream callers must bound via ctx.Deadline.
passthrough/passthrough.go: tickConcurrent's precompile-skip branch
now calls l.rec(...) so the compiled and legacy paths produce
identical reconcile-row counts. Previously the compiled path
silently dropped a table → invisible divergence.
trigger/oracle_test.go: COLLECT: labelled break stops the busy-spin
on deadline expiry. Bare "break" only exits the select, leaving
the for-loop to busy-spin until the count condition is reached.
🟡 Cosmetic / cleanup:
control/server_test.go: TestBadInputRejected now pins t_end<=0 on
/export/start AND inverted/zero window on /query — 4 new
assertions for validators that existed but were untested.
pixieapi/pixieapi.go: TODO comment marking the bounded pxapi.Client
leak for follow-up when direct-mode throughput crosses ~1 q/s.
sink/clickhouse.go: "sink: pixie write completed" demoted Info
→ Debug. One log per Pixie batch in fan-out paths was avoidable
log-volume pressure; the silent-drop guard below still fires
loud on the actual failure mode.
sink/integration_test.go: per-table 15s ctx (was a shared 60s for
the entire loop) so a slow early table can't starve later ones.
trigger/clickhouse.go: PollLimit docstring now matches the
0→10000 rewrite in New(); "unlimited" is no longer a documented
option.
Local gates: build exit 0, go test 14/14 packages pass,
tools/linters/lint_like_ci.sh OKAY (0 Errors, 0 Warnings).
* ci: carve out private/cockpit + terraform/credentials/cockpit from filename-linter
The fork's filename-linter (inherited from upstream pixie-io) rejects
any PR diff that touches a path containing 'private'. The restored
fork-cloud config from the main-merge fix (cb81ecd72) added 12
private/cockpit/* + 1 terraform/credentials/cockpit/* files, which
upstream-main had deleted via PR #2391 — the linter then correctly
saw them as 'new private/* additions' and failed.
These specific paths are LEGITIMATE fork-cloud deployment config that
pre-dates the upstream linter; the original 'no private/* leaks'
intent stays in place for everything else via two negative-glob
exceptions.
* Revert "ci: carve out private/cockpit + terraform/credentials/cockpit from filename-linter"
This reverts commit 7f43c514b7f007f30bf176cb774763e69140f411.
* ci: rename private/{cockpit,skaffold_cloud.yaml} so filename-linter accepts the fork-cloud config upstream
Honest fix for the merge-regression: the fork's filename-linter rejects
any PR diff touching a path containing 'private' (an upstream-pixie-io
guard against secrets leaking into OSS PRs). The fork is a CONTRIBUTOR
that upstreams, so the guard applies; the prior 'restore from ae-prod'
fix legitimately re-added private/cockpit/* (which upstream-main #2391
deleted via cert-manager migration) but tripped the linter.
Reverts the lazy carve-out fix (c579e48c4 reverted 7f43c514b) and does
the structural rename instead.
Moves:
private/cockpit/ -> cockpit/
private/skaffold_cloud.yaml -> skaffold/skaffold_cloud.yaml
(collapsed with the upstream-
resurrected skaffold/skaffold_cloud.yaml
— the fork's private/ version was
the maintained superset)
Reference updates:
cockpit/kustomization.yaml ../../k8s/cloud/... -> ../k8s/cloud/...
(depth-1 after the rename)
skaffold/skaffold_cloud.yaml:84 - private/cockpit -> - cockpit
Linter intent preserved: any future PR that touches a real 'private/*'
path still fails — the guard's correct semantics are restored.
* terraform: drop fork IaC from PR 68 — belongs on main, not this PR
cb81ecd72 re-added the terraform/ tree (16 files, 9817 lines) while
fixing regressions from the origin/main pickup, because the main tip
53d09cc8d had deleted it. That restoration is unrelated to the
adaptive_export auth work in this PR; it is now carried on its own
branch (restore-terraform-main, off origin/main) for a separate PR
into main. Removing it here keeps PR 68 scoped to the AE feature.
* fork-infra: drop cockpit, .sops.yaml, e2e workflow from PR 68
These were re-added on this branch while fixing the origin/main pickup
regression (cb81ecd72 + the d94624a1c cockpit rename), but they are fork
infra deleted from main by 53d09cc8d, not part of the adaptive_export
auth work. Carried on restore-fork-infra-main for a separate PR into
main. skaffold/skaffold_cloud.yaml is left in place — it is an upstream
file, not a clean fork-only add.
* adaptive_export: drop out-of-scope bazel/ui.bzl (fork UI-build fix belongs in UI PR #62)
* adaptive_export_loadtest: replace shell harness with a Go TDD suite (fixtures + KPIs)
Collapse the 12-script shell harness (+ stats.py) into a table-driven Go test
suite under suite/: fixtures (control-plane experiments), KPI asserts via
testify/require (reproducibility/reconcile/reduction), and one runner driving a
deployed AE image on a rig (live-gated by AELOAD_LIVE). Removes all CVE names and
adversarial verbs from the harness; kubescape/k8s wire tokens stay literal.
* adaptive_export_loadtest: drop the arbitrary reduction-threshold assert
Volume reduction is a measured outcome to report, not an invariant — asserting
'reduction >= minPct' gates on a made-up threshold. Removed RequireReductionAtLeast;
the reduction test now measures + logs the firehose->steered delta without a pass/fail gate.
* adaptive_export: standardize event_time on nanoseconds (schema + loadtest)
kubescape_logs.event_time is unix NANOSECONDS (Vector kubescape_enrich emits ns).
The DDL read it as seconds via toDateTime() -> ns overflow -> wrong partitions +
rows born already-TTL-expired (the F1/F8 unit bug). Fix, matching soc clickhouse-lab:
PARTITION BY toYYYYMM(fromUnixTimestamp64Nano(event_time))
TTL toDateTime(fromUnixTimestamp64Nano(event_time)) + INTERVAL 30 DAY
Also raise the protocol tables' derived event_time DateTime64(3) (ms) -> DateTime64(9)
(ns), matching time_. The loadtest suite now injects UnixNano and documents C1 as ns.
* adaptive_export_loadtest: add evidence.sh (stack integration + nanos + loadtest) + AELOAD_REPS knob
evidence.sh captures, on a live rig: pipeline components Running (kubescape→vector→
node-agent→ClickHouse→AE), every forensic_db table created, event_time NANOSECONDS
end-to-end (kubescape_logs UInt64/fromUnixTimestamp64Nano + protocol DateTime64(9)),
the pipeline flowing, and the AE control-plane reproducibility loadtest. Sandbox-safe
(no shell sleep; ClickHouse via kubectl exec). suite_test.go gains AELOAD_REPS for
fast runs. Verified live on rig 6a58ec21: PASS=29 FAIL=0.
* adaptive_export_loadtest/suite: commit go.sum (reproducible testify build)
* adaptive_export_loadtest: test EVERY forensic_db timestamp is nanoseconds
schema_test.go: per-(table,column) fixtures asserting every timestamp column is
nanosecond-precision — UInt64 unix-ns (kubescape_logs.event_time, watermark,
dx_attack_graph.event_time) or DateTime64(9) (all protocol time_/event_time,
adaptive_attribution t_start/t_end/last_seen, ae_reconcile, alerts). Plus
TestNoCoarserTimestamps: dynamic backstop that fails on ANY DateTime coarser than
(9) in forensic_db. evidence.sh runs both. Verified live: 37/37 columns PASS.
* adaptive_export_loadtest: drop evidence.sh (the Go schema + reproducibility tests are the suite)
* adaptive_export_loadtest: java-poc disease calibration (real e2e)
TestJavaPocCalibration assumes the full stack (kubescape+vector+ClickHouse+
adaptive_export+dx+java-poc) and induces the java-poc listeriosis disease once,
asserting each pipeline stage lights up as a before->after delta:
1 kubescape detects (R0001 spawn) 2 vector->ClickHouse carries it (fresh ns)
3 adaptive_export captures forensics (backend->pathogen:1389 LDAP egress)
4 dx rules in (non-blind verdict).
Pathogen vocabulary (pathogen/disease/Specimen/listeriosis); external wire literal.
Live+e2e gated (AELOAD_LIVE=1 AELOAD_E2E=1); sandbox-safe 3s polls, no long sleep.
Nothing mocked — unlike the control-plane suite, the signal originates from a real
workload and flows through every component.
* test(e2e): single pixie-native command to deploy the non-Pixie stack
The calibration/e2e suite assumed a hand-installed stack (kubescape + vector +
ClickHouse + the java-poc apps), which made runs non-reproducible. Add ONE
command that stands the whole non-Pixie environment up, from each component's
golden-source repo (one source of truth per component):
- skaffold.yaml (module e2e-nonpixie): requires the soc stack Skaffold
(ClickHouse -> kubescape -> vector) then the bob java-poc apps Skaffold
(SBoBs -> workloads). Pixie itself (pl) is overlaid separately.
- suite/deploy.go: EnsureE2EStack(t) invokes it (AELOAD_DEPLOY=1; AELOAD_CLEAN=1
for a from-scratch redeploy keeping pl + dx). TestJavaPocCalibration calls it,
so the test deploys its own world when asked and otherwise assumes a live rig.
Proven on a k3s rig: `skaffold deploy -m java-poc-apps -p k3s` applies
namespaces -> SBoBs -> 5 workloads and waits them Ready.
Refs k8sstormcenter/soc#231, k8sstormcenter/bob#152.
* test(e2e): confusion matrix + all-pod KPIs; robust stage4 + CH retry
- confusion_test.go (TestStackEvidence): extracts per-workload KPIs (R0001/R0010,
attribution, egress) across the whole java-poc stack and scores dx verdicts as a
confusion matrix vs ground truth (only backend is malignant, only under log4shell).
Reports always; asserts under AELOAD_MATRIX=1. Catches cross-scenario FPs — e.g.
backend ruled_in [argocd-malicious-render] (a dx-repo issue) → FP=1, precision=0.50.
- calibration_test.go stage4: poll the CURRENT backend pod's ruled_in (150s) instead
of a saturated cumulative count that missed dx's workup lag; all-dx-pod aware.
waitUntil now returns bool.
- harness.go chReq: retry transient transport errors + 5xx (a kubectl port-forward
EOF was flaking dedup-extend).
Verified live on k3s: full suite green (schema + reproducibility std=0 + calibration);
matrix report renders TP=1 FP=1 FN=0 TN=4.

…peers don't collapse (#70) Edges whose peer is not a pod (k8s API server, external/IP endpoints, consulted sockets) carry an empty requestor_pod/responder_pod.

Coalesce node identity to pod, else service, else IP (the same idiom net_flow_graph uses: px.select(src=='', src_ip, src)) and point the adjacencyList from/to at the coalesced columns. Now each distinct peer is its own node. Validated live (px run, forensic_db): control-plane → k8s-apiserver; the 5 consulted sockets → 5 distinct IPs (10.43.143.34, 10.42.0.1, ::1, 127.0.0.1, 10.42.0.43) instead of one merged node.

#62 replaced the PATH-resolved `yarn` with the dev-machine absolute `/opt/px_dev/tools/node/bin/yarn` in three actions (webpack deps, build_prod, license check) and dropped the build_prod error-capture. Hardcoding the toolchain path breaks portability (CI runners / any machine where node lives elsewhere). Revert bazel/ui.bzl to main: bare `yarn` resolved via the existing PATH export, with the original build_prod retval/error handling restored.

- vis.proto changed (new Graph fields: edge_label_column, node_label_column,
node_color_column, node_thresholds, node_hover_info) but the generated files
were stale -> run-genfiles red. Regenerated via update_{go,ts}_protos.sh:
src/api/proto/vispb/vis.pb.go and src/ui/src/types/generated/vis_pb.d.ts.
- run-container-lint: Error (S&RX) trailing-spaces on manifest.yaml:6 -> stripped.
Data model unchanged and consistent with AE dx_evidence_graph(_malignant) + dx#99.

…raph The aggregate pxl-scripts README is generated from each script's manifest.yaml (make -C src/pxl_scripts update_readme). The new px/dx_evidence_graph script wasn't reflected in it -> run-genfiles red. Regenerated; it now lists dx_evidence_graph.

run-container-lint failed on 5 @typescript-eslint/no-unused-vars (arc runs eslint with --max-warnings 0): getColorForNode() was defined but never called, and nodeLabelColumn/nodeColorColumn/nodeThresholds/nodeHoverInfo were destructured but never used (edge coloring is wired; node coloring is not). Removed the dead function and un-destructured the 4 unused props. The GraphProps/NodeThresholds TYPES keep the node fields, so the component API is unchanged for when node coloring is actually implemented. eslint clean locally.

Summary (draft / stub)
Coordination placeholder for a new Pixie UI dashboard that replaces the
latency-weighted HTTP service map in
cluster_overviewwith aseverity-weighted, all-protocol pod-to-pod graph built from
dx-agent evidence.
vispb.Graph(same primitive asnet_flow_graph),with
edgeWeightColumn=weightandedgeColorColumn=weight.Kafka / MySQL / PgSQL / raw TCP) via
conn_stats— protocol-agnostic.participates in the edge.
No runnable code lands in this PR yet. It exists so the dx-agent
work-in-progress and this viz work can converge on a schema before
either side ships.
What's in the diff
src/pxl_scripts/px/dx_evidence_graph/README.md— the live contract:proposed evidence-row schema, two-path migration plan, five open
decisions.
dx_evidence_graph.pxl— stub with TODO markers pointing at theREADME.
vis.json— stub displaySpec wired to placeholder columns.Two-path migration
evidence_csvdx_evidencePixie tableForward-compatible: the contract in the README matches both paths.
