The primary agent model defaults to +`gemini-3.5-flash` (override with `AGENT_MODEL`); the judge defaults to +`gemini-3.1-pro-preview` (override with `JUDGE_MODEL`), regardless of which +agent is under test. The per-task agent timeout defaults to 1800 seconds +(override with `AGENT_TIMEOUT_SEC`). + +## `--no-infra` vs `--infra` + +Provisioning is the **default**. With no infra flag, `run.sh` runs a normal +tofu bringup: builds a fresh, run-scoped cluster, lets tofu seed it (for +`ledger-read-facade` and `checkout-multi-service-outage` that means a +`null_resource` applying the fixture during `tofu apply`; see below), runs +the agent, then tears the cluster down, exactly like a plain +`python -m devops_bench` run without `--no-infra`. Under this path the shell +cleanup/seed/preflight hooks in this directory are skipped (tofu already +owns seeding), and so is the kubectl current-context assertion described +below, since there is no pre-existing cluster to assert against; the run +creates its own. + +`--infra` is accepted as an explicit, **no-op alias** for the default: pass +it if you want the mode spelled out for readability, but it does not change +behavior. + +`--no-infra` is the **opt-in fast loop** against an already-standing +cluster. It skips provisioning and reuses whatever cluster is already +configured. Most of these tasks (`deployer: "tofu"`) depend on +tofu-**seeded** cluster state (broken configs, Kyverno policies, bare +GitOps repos, etc.), so `--no-infra` instead drives the +cleanup -> seed -> preflight sequence itself (see below) for any task that +has a `scripts/isorun/seed/.sh` hook, and it verifies your +current kubectl context matches `$CLUSTER` before touching anything, since +under this path the cluster already exists and must be the right one. + +`run.sh` still prints a prominent warning when you run a tofu-backed task +with `--no-infra` and that task has **no** seed hook, as a reminder to check +the seed is actually there before trusting the result. Tasks with a seed +hook do not print this warning: seeding and its correctness are handled by +the seed and preflight steps instead. `--no-infra --no-seed` skips the seed +and preflight hooks too, but the kubectl context assertion still runs (see +[`--no-seed`](#--no-seed) below). + +## Cleanup hooks + +Under `--no-infra` (and without `--no-seed`), `run.sh` looks for +`scripts/isorun/cleanup/.sh` (keyed off the task's directory +name, e.g. `cve-remediation` for `tasks/common/cve-remediation/task.yaml`) +and runs it as a pre-run reset. Each hook is idempotent (safe to run when +nothing exists yet) and only deletes what that task creates; it leaves +tofu-owned/tofu-destroyed resources (the cluster, Secret Manager secrets, +the Lustre instance, etc.) alone. Under the default provisioning path, or +with `--no-seed`, this step is skipped: tofu owns seeding during bringup and +teardown, so there is nothing for the shell hook to reset. + +## Fixtures, seed hooks, and preflight guards + +These three directories only exist for the tasks in the fast-iteration loop +(`fix-config`, `deploy-config`, `optimize-scale`, `ledger-read-facade`, +`checkout-multi-service-outage`); other tasks are unaffected and behave +exactly as before. + +- **`fixtures/.yaml`**: standalone, kubectl-appliable manifests + that recreate a tofu stack's in-cluster pre-agent state, for `fix-config` + and `optimize-scale`. Each file's header comment states which tofu stack + and `seed_mode` it was derived from. These are **hand-maintained copies + for fast local iteration, not generated artifacts**: tofu remains the + source of truth for real graded runs, and a fixture can silently drift out + of sync if the tofu stack changes and the fixture isn't updated to match. + `deploy-config` has no fixture file of its own; its only seeded object (a + Workload Identity ServiceAccount) is small enough to inline in its seed + script. `ledger-read-facade` and `checkout-multi-service-outage` don't use + this directory at all: their fixtures live at + `tf/prebuilt/-kind/manifests/.yaml`, a single source of truth + applied both by their dedicated tofu stack (via a `null_resource` during + `tofu apply`) and by their `scripts/isorun/seed/.sh` hook, so + there's no copy to drift out of sync. + +- **`seed/.sh`**: runs after the cleanup hook, unless `--no-seed` + is passed.
