Brief: the risk graph as a tool (to dev, from a collaborator's ideas)

Status: for dev@php.newsroom to act on; the steps below need no decision from the editor. Author: the Sherpa (sherpa@php.newsroom), at the editor's request on 23 October 2026, from the collaborator's message recorded as CI-002 (/sherpa/ideas/ci-002/), which continues CI-001. Each step is a board row (166 to 170). Two of his points wait for the editor and are listed at the end.

Why

The collaborator's reading of the risk graph: "the biggest opportunity is turning the graph from a visualization into an actionable tool for understanding security impact and making decisions." Measured on v0.10.10, the graph holds 442 nodes and 914 edges, every edge a verb with its named inverse. The overview draws all of it at once; nothing starts from one node; no edge says how it is known; nothing runs from code upwards; the gaps are not computed. Each step below fixes one of those, on the data the site already has.

The steps

StepWhatHis ideaBoard
1A focus view. Open the graph at any node (a CVE, a risk, a stakeholder, a function, a control): its direct neighbours, grouped by verb; expand any neighbour with a click; the path back to the start always shown; the focus and the expanded nodes in the address, so a view can be shared. In the browser, from data/grc-graph.json; no new data.Progressive exploration (CI-002.3)166
2A basis on every edge. basis: source (with the capture's slug), code (with the commit), inferred (with the agent), confirmed (with who checked). Checked in build_grc(), which already stops on an unknown reference, so the gate's own files need no change. Inferred edges drawn dashed, with a switch to hide them; each edge links to what supports it. Start by marking what is known: edges built from data/code.json are code, edges from a claim are source; the rest inferred until checked.Evidence and confidence (CI-002.5, CI-001.5)167
3Tests as nodes. The fix commit touched tests/, ext/zend_test and run-tests.php; today those are directory areas in the review graph. Each test file of the commit becomes a node, joined (tests / tested_by) to the remediation and code it exercises, read from the commit.Traceability (CI-002.4, CI-001.8)168
4An impact view. Pick a function or file; climb the graph upwards: remediations, vulnerabilities, weaknesses, risks, controls, stakeholders, each with its path. User stories join when they exist.Impact analysis (CI-002.6)169
5A gaps page. Computed at every build from rules written as data: a control with no path to a test; code with no owner; a risk with no story, treatment or holder; an edge with no basis (after step 2). Each gap with its count, its list and who could close it. On v0.10.10: none of the 16 code nodes has an owner one step away; none of the 95 controls reaches code or a test; no tests; 14 of 34 risks join no story directly.Missing relationships (CI-002.8)170

Order: 2 before 5 (the gaps page reports edges with no basis); 1 and 4 share one component (a focus view that can climb). Each step is deterministic, built from the data, with a markdown twin, and works on a phone.

Waiting for the editor

  • The design direction (CI-002.1): the collaborator prefers an editorial main experience with the graph behind an explicit step for depth. The redesign's mockups are under the editor's review (/admin/design/).
  • Persona views of the graph (CI-002.7): which nodes and verbs each of the three views (executive, security leader, operator) shows by default, after the redesign is decided.
  • User stories as a layer (CI-002.4): whose stories (PHP's own, or a reader's application's) is an editorial call.
