The README is the live contract: - proposed evidence-row schema (time_, pod, severity, criterion, ...) - two-path migration plan (script-args in v1 -> dx_evidence table in v2) - five open decisions blocking implementation (edge severity reach, time anchor, hop depth, multi-evidence aggregation, script placement) No runnable code lands yet; .pxl and vis.json carry TODO markers pointing at the README so the dx-agent's data-model decisions show up in one place. v1 implementation is ~1-2 days once decisions settle. --- .../px/dx_evidence_graph/README.md | 108 ++++++++++++++++++ .../dx_evidence_graph/dx_evidence_graph.pxl | 80 +++++++++++++ src/pxl_scripts/px/dx_evidence_graph/vis.json | 44 +++++++ 3 files changed, 232 insertions(+) create mode 100644 src/pxl_scripts/px/dx_evidence_graph/README.md create mode 100644 src/pxl_scripts/px/dx_evidence_graph/dx_evidence_graph.pxl create mode 100644 src/pxl_scripts/px/dx_evidence_graph/vis.json diff --git a/src/pxl_scripts/px/dx_evidence_graph/README.md b/src/pxl_scripts/px/dx_evidence_graph/README.md new file mode 100644 index 00000000000..7fdf1e3ab6d --- /dev/null +++ b/src/pxl_scripts/px/dx_evidence_graph/README.md @@ -0,0 +1,108 @@ +# dx evidence graph — coordination stub + +**Status:** stub.

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).

Script now binds to the locked attackgraph.Edge schema via PxL, filterable by investigation_id, with the DSN exposed as a UI script- arg (default = the in-cluster soc deployment) so per-cluster overrides happen in the script-args panel rather than the bundle. //src/pxl_scripts:script_bundle_test still passes.

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) 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.

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.

The cloud-release pipeline ALREADY bakes a current bundle into cloud-proxy_server_image as /bundle/bundle-oss.json (src/cloud/proxy/BUILD.bazel: script_bundle layer), and nginx serves it at /bundle-oss.json from both the bare-domain and the work.* subdomain server blocks (k8s/cloud/base/proxy_nginx_config.yaml lines 270 and 342). Switch the cockpit overlay to a relative URL ("/bundle-oss.json") so the UI's fetch resolves against document.baseURI (the proxy itself) and consumes whatever the release pipeline shipped. This means cloud-release tags are now self-sufficient: every skaffold-deploy step picks up the new bundle automatically.
