Struct State 

pub struct State {
    pub stage: Stage,
    pub phase: u32,
    pub agent: AgentKind,
    pub mode: Mode,
    pub gate_pending: bool,
    pub consecutive_failures: u32,
    pub infra_failures: u32,
    pub preflight_retries: u32,
    pub started_at: String,
    pub project_root: PathBuf,
    pub worktree_path: Option<PathBuf>,
    pub monitor_pid: Option<u32>,
}

Full workflow state persisted to .devflow/state.json.

Fields

stage: Stage

Current workflow stage.

phase: u32

Phase number being worked on.

agent: AgentKind

Which coding agent was launched.

mode: Mode

How the pipeline is driven (auto vs. supervise).

gate_pending: bool

Whether a gate has been written and is awaiting a human response.

consecutive_failures: u32

Consecutive Validate failures — drives the Auto-mode forced gate after crate::mode::MAX_CONSECUTIVE_FAILURES failures. Persisted across devflow advance invocations so the counter survives monitor restarts.

infra_failures: u32

Consecutive infrastructure-class faults (ResourceKilled, AgentUnavailable) — distinct from Self::consecutive_failures (D-08, 17-01). Gates at crate::mode::MAX_INFRA_FAILURES. Any increment (wired in Plan 04) must use saturating_add so a long-running stuck loop cannot overflow u32. A serde-absent value (older persisted state) defaults to 0. Reset to 0 on every successful stage transition, alongside consecutive_failures (CR-01, 17-06 gap closure), so the ceiling bounds a stuck loop, not a phase’s lifetime.

preflight_retries: u32

How many times a preflight gate has been resolved and retried for this phase (18f). Bounded by crate::mode::MAX_PREFLIGHT_RETRIES. Persisted rather than recursion-scoped because the documented wedge spanned separate devflow invocations after a monitor death — an in-process recursion-depth counter would reset to zero on every new process and fail to bound the exact incident it exists to prevent. Reset to 0 whenever preflight passes and whenever a human explicitly approves (GateAction::Advance), both inside run_preflight. Unlike Self::consecutive_failures and Self::infra_failures, this counter is NOT touched by transition().

started_at: String

When the phase started (Unix seconds).

project_root: PathBuf

Path to the project root.

worktree_path: Option<PathBuf>

Working directory for the agent when running in a git worktree.

None means the agent runs in project_root. State and capture files always live under the main project_root; only the agent’s cwd changes.

monitor_pid: Option<u32>

PID of the detached monitor process that owns the agent for the current stage, recorded by launch_stage at spawn time. None means no monitor has been spawned for this state yet, OR the state was written by a binary predating this field — in both cases the liveness probe reports Unknown, never Stuck.
