    "incantation": "When a Dagger workspace needs reproducible selected lookups, run with `--lock live`, `--lock pinned`, or `--lock frozen` to control lookup resolution. Run `dagger lock update` to refresh recorded entries; in v0.21.0 it also creates `.dagger/lock` when missing.",
    "examples": [
      "dagger --lock live <command> [arguments...]",
      "dagger --lock pinned <command> [arguments...]",
      "dagger --lock frozen <command> [arguments...]"

    "gotchas": [
      "Version: v0.21.0",
      "--lock live: Opts into live resolution and records live values.",
      "--lock pinned: Opts into using recorded pins where available and resolving the rest live.",
      "--lock frozen: Opts into resolution only from `.dagger/lock`.",
      "dagger lock update: Refreshes entries already recorded in `.dagger/lock`; creates the file when it is missing.",
      "Locking is opt-in.",
      "The lockfile applies to selected lookups such as `container.from` and Git refs.",
      "Docs conflict: Current Dagger lockfile documentation describes `dagger.lock` and newer lock-mode behavior; it differs from v0.21.0's `.dagger/lock` paths, so newer behavior was excluded."
