It reads your repository — test code, source structure, coverage data, runtime artifacts, ownership files, and local policy — and builds a structural model of how your tests relate to your code.

Test runners (Jest / pytest / Go test / Playwright / Promptfoo) continue to execute; Terrain reads what they produce, models the system as one thing, and gates against it. -The core idea: every codebase has a *test terrain* — the shape of its testing infrastructure, the density of coverage across areas, the hidden fault lines where a fixture change cascades into thousands of tests. Terrain makes that shape visible and navigable so you can make informed decisions about what to test, what to fix, and where to invest. +When the testing surface drifts from the code surface — exports without tests, frameworks fragmenting across directories, AI surfaces shipping without scenarios, one team's posture diverging from another's — Terrain shows where the drift is and what convergence would take.

It analyzes the test system around them. Pair it with `jest`, `pytest`, `go test`, your existing CI runner — Terrain reads the artifacts those produce, it doesn't replace them. +- **Not a coverage tool.** Terrain ingests coverage reports if you have them and uses them as evidence, but it doesn't instrument code or compute coverage itself.

Hygiene findings appear but don't block +the merge in the recommended config. + +## Why we recommend this exact shape + +There are many ways to wire eval results into CI. We landed on +this shape after the launch-readiness review for two specific +reasons: + +1. **One comment, not two.** Adopters running Promptfoo + independently of Terrain end up with two PR bots talking past + each other — eval pass/fail in one comment, structural coverage + in another. The unified shape uses Promptfoo's output as raw + material for *Terrain's* comment; only one bot speaks per PR. +2. **Baseline-aware default.** `--new-findings-only --baseline` + means established repos with existing AI debt don't brick on + day one. Adopters who turn on `--fail-on critical` after a + month of Inventory cleanup never see an avalanche of legacy + findings. + +The "warn-only by default" trust ladder +([`docs/product/trust-ladder.md`](../../../product/trust-ladder.md)) +is the alternative for adopters who want to see findings before +committing to a blocking gate. This walkthrough assumes +`--fail-on critical` is the destination; adjust the template if +you're earlier on the ladder. + +## What this example does NOT do + +Documented up front so adopters don't infer a contract that +isn't there: + +- **Doesn't run your tests.** Promptfoo runs its tests; Terrain + reads the output. We never invoke your test runner. +- **Doesn't ship API keys.** `OPENAI_API_KEY` is consumed by + Promptfoo (a child process Terrain optionally spawns). Terrain + does not read, log, or proxy the key. See + [`docs/product/ai-trust-boundary.md`](../../../product/ai-trust-boundary.md). +- **Doesn't sandbox eval execution.** Sandboxing is on the 0.3 + roadmap. If your prompts include tool-call shapes that touch + filesystem or network, the sandbox is the eval framework's + responsibility in 0.2. +- **Doesn't replace Lakera / Guardrails.** Those are + request-time AI safety services. Terrain solves the structural + / pre-deploy / inventory side. Both can coexist. + +## Troubleshooting + +### "Eval results JSON not found" + +Confirm Promptfoo's `--output` path matches the +`--promptfoo-results` path in the Terrain step. The workflow +uses `out/promptfoo.json` for both; if you change one, change +both. + +### "Terrain reports unfamiliar Promptfoo shape" + +Track 7.2 surfaces a single warning when Promptfoo's output shape +doesn't match v3 or v4. The warning text names the specific drift. +Most often it means Promptfoo got upgraded and the export shape +shifted; file an issue with the Terrain version + Promptfoo +version and we'll add a conformance fixture. + +### "PR comment is missing the AI Risk Review section" + +The AI section only renders when Terrain detects AI surfaces in +the changed files OR has eval results to summarize.

Their +imports become edges in Terrain's import graph, and from those edges +Terrain can answer: "if I change `src/auth/login.ts`, which tests +should I run?" The graph traversal is sound; the imports are +ground truth; the attribution is precise. + +E2E tests don't work that way. A Playwright spec navigates to +`http://localhost:3000/login`, types into a form, clicks a button, +and asserts on rendered DOM. Nothing in that file imports +`src/auth/login.ts`. The test exercises the same code path that +unit tests exercise — but the link between the two is not in the +import graph. + +This is a real limit, not a Terrain shortcoming. Every static- +analysis tool faces it: e2e tests are deliberately decoupled from +implementation so they survive refactors, and that decoupling +removes the import-graph signal Terrain relies on for unit / +integration attribution. + +## What 0.2 does + +Terrain attributes e2e tests to code units only via **structural** +signals. Adopters should read these as best-effort heuristics, not +as ground truth. + +### 1. Path co-location + +If `e2e/login.spec.ts` lives next to a feature directory whose +sibling unit tests link to specific code units, e2e attribution +borrows those links transitively. Confidence: **medium**. Common +case: a monorepo packages directory where each feature owns both +its unit tests and its e2e specs. + +### 2. Declared associations in framework configs + +Playwright and Cypress configs sometimes declare which routes / +features each spec exercises (via `testMatch` patterns or +`describe()` titles). When parseable, Terrain folds those +declarations into the link set. Confidence: **medium-high** when +the config is explicit, **low** when only the test name carries +the signal. + +### 3. Shared fixture paths + +If an e2e spec imports a fixture file (page-object, test-data, +auth-helper), and that fixture is imported by other tests with +known code-unit links, Terrain transitively links the e2e spec to +those code units. Confidence: **low** — fixtures are often shared +across many features and the transitive link can be loose. + +### 4. Convention-based mapping (last resort) + +For repos without explicit configs or co-location structure, +Terrain falls back to convention: the `e2e/auth/` directory is +assumed to exercise `src/auth/`. Confidence: **low**, marked as +`structural-only` in evidence. + +## What 0.2 explicitly does NOT do + +These are out of scope and remain so until 0.3 or later. We +document them up front so adopters don't infer guarantees that +aren't there. + +### Runtime trace ingestion + +A natural way to close the gap is to run the e2e suite once with +coverage instrumentation, capture which source lines each spec +hits, and use that as ground truth. We don't do this in 0.2. It +requires running tests, which Terrain explicitly does not do (see +[`docs/product/ai-trust-boundary.md`](ai-trust-boundary.md)). +Adopters who want coverage-grade e2e attribution should run their +e2e suite with `--coverage` and feed the resulting LCOV / Istanbul +artifact through Terrain's coverage ingestion path. Terrain will +read it. Terrain will not produce it. + +### URL-to-route mapping + +A web app's e2e spec navigates to `/login`. The route handler is +in `src/routes/auth.ts:loginHandler`. Linking the two requires +parsing the framework's router config (Express, Next.js, FastAPI, +Rails) and matching URL patterns to handler functions. We don't +do this in 0.2. The router-parsing surface area is large +(every framework has a different shape) and the precision / +recall trade-offs are not yet measured. + +### DOM-selector to component mapping + +A Playwright spec interacts with `page.locator('[data-testid="login-button"]')`. +The component that renders that button is `src/components/Login.tsx`. +Linking the two requires parsing the test for selectors, parsing +the source for component definitions, and matching them. We don't +do this in 0.2. Test selectors aren't standardized — `data-testid`, +`aria-label`, `id`, role-based, text-based — and matching them +correctly across rebuilt components is research-grade work. + +### Cross-language e2e attribution + +A Playwright spec written in TypeScript exercising a Go backend +service via HTTP. The backend handlers are in +`internal/handlers/users.go`. Cross-language linking is not in 0.2. +The import-graph crosses ecosystems imperfectly even for unit +tests; for e2e, where the link goes through a network boundary, +we explicitly do not attempt it. + +## How this surfaces in output + +When Terrain reports impact analysis on a change to source code: + +``` +terrain report impact --base main +``` + +The output now distinguishes attribution confidence per test: + +``` +Recommended Tests + src/auth/__tests__/login.test.ts [exact] (import-graph) + Covers: src/auth/login.ts:loginUser + e2e/auth/login.spec.ts [structural-only] (path co-location) + Covers: src/auth/login.ts (file-level, not symbol-level) + e2e/checkout.spec.ts [convention] (low confidence) + Reason: directory mapping suggests this exercises src/checkout/ +``` + +The `[exact]` / `[structural-only]` / `[convention]` tag is the +attribution-confidence signal. `--explain-selection` (added in +Track 3.2) renders the full reason chain — important for e2e +because the reasons are looser than for unit tests and adopters +need to inspect them. + +When `terrain report posture` is invoked, the analysis-completeness +signal flags repos where e2e attribution is the only source of +coverage for a code unit: + +``` +Posture + coverage_diversity: ELEVATED + e2e/checkout.spec.ts is the only test linked to src/checkout/cart.ts + — but the link is structural-only. Treat this as suggestive, + not as proof of coverage. +``` + +## Why we ship structural-only attribution at all + +The alternative — emitting *no* link for e2e specs — is worse than +shipping low-confidence links that adopters can inspect. With no +link, `terrain report impact` would silently exclude e2e specs +from the recommended-tests set whenever a source file changed, +even when the e2e spec is the only test exercising that path. With +low-confidence links plus an honest `[structural-only]` tag, +adopters see the link and can decide: trust it for now, or run all +e2e specs as a precaution, or invest in coverage instrumentation. + +The same principle drives every limit on this page: visible +imperfection beats invisible omission. + +## 0.3 roadmap + +Order of likely investment: + +1. **Coverage-artifact ingestion for e2e** — read LCOV / Istanbul + produced by `playwright test --coverage` and use it as ground + truth, replacing the structural fallback whenever present. +2. **Router config parsing** — Express, Next.js, FastAPI, Rails. + Map URLs in test specs to handler functions in source. +3. **Selector-to-component mapping** — opt-in per repo via a + `.terrain/e2e-config.yaml` that declares the selector + convention used (e.g. `data-testid` only). + +None of these are 0.2 work.

The registry is additive: any +// caller (printUsage, doctor, truth-verify, docs-gen) can read +// from it today without forcing the dispatcher to become +// registry-driven. +// +// Why a separate package +// +// Putting the registry under cmd/terrain/ would couple it to the +// CLI binary's package and make it un-importable from +// internal/signals (where truth-verify will eventually want to +// cross-check command names against the manifest). internal/cli +// is the right home: importable from anywhere in the tree, no +// dependencies on cmd/. +// +// What the registry does NOT do +// +// - Argument parsing. Each command keeps owning its own flag.FlagSet. +// - Dispatch. The big switch in main.go stays the source of truth +// for how arguments map to runFoo() calls, until a 0.2.x PR +// migrates it. +// - Help-text generation. printUsage can opt in to read from +// here, but doesn't have to. +package cli + +import ( + "fmt" + "sort" + "sync" +) + +// Pillar names the product pillar a command belongs to.
