AGENTS.md documents 'Test unit: go test ./pkg/...' and 'E2E tests: go test -tags e2e ./pkg/e2e/'. Both statements were false: no file in pkg/e2e carried an e2e build constraint, so the -tags flag was a no-op and the 'unit' command actually launched the full e2e suite — requiring a Docker daemon and the locally built binary, creating and destroying containers, for up to 20 minutes. CI only avoided this by grepping e2e out of the package list (Dockerfile). Every *_test.go in pkg/e2e now carries //go:build e2e (merged with the existing !windows constraints), and the Makefile e2e targets pass the tag. The documented commands become true: - go test ./pkg/... -> pkg/e2e reports [no test files] - go test -tags e2e ./pkg/e2e -> runs the suite AGENTS.md now also states the daemon/binary prerequisites explicitly. Part of #14074 (A: the code misdescribes its own structure). Signed-off-by: Nicolas De Loof <[email protected]>
