Struct Policy 

pub struct Policy {
    pub max_attempts: u32,
    pub rate_limit_cooldown: Duration,
    pub burn_cooldown: Duration,
    pub transient_cooldown: Duration,
    pub no_checkbox_deadline: Duration,
    pub warm_timeout: Duration,
    pub lease_timeout: Duration,
    pub probe_concurrency: usize,
    pub slim_timeout: Duration,
    pub slim_connect_timeout: Duration,
    pub redirect_mismatch_backoff_base: Duration,
    pub redirect_mismatch_backoff_max: Duration,
}

Tunables for retry/cooldown behaviour, the headed-solve deadlines, pacing, and probing. Read off Config::policy; Policy::default is sensible for most runs.

Fields

max_attempts: u32

The per-request rotation budget — how many exits a raw challenge burns through before giving up (winnable failures re-queue without spending it, so they retry forever).

rate_limit_cooldown: Duration

How long a rate-limited (CF 1015) exit rests before it’s leasable again. Deliberately short.

burn_cooldown: Duration

How long a reputation-blocked (CF 1020) exit is benched — longer than a rate-limit.

transient_cooldown: Duration

How long a transient blip (5xx / odd-transport) benches an exit before a retry elsewhere.

no_checkbox_deadline: Duration

How long the headed solver waits for the challenge checkbox to appear before giving up.

warm_timeout: Duration

Total solve budget for a warming solve — much shorter than a headed fetch_browser’s --timeout. Warming is speculative bulk work across the whole catalog, so a single stuck exit must not hold one of the few (B) browser slots for the full minute: give up fast and let the slot try a warmable exit. (A headed fetch the caller explicitly asked for still gets the full --timeout.)

lease_timeout: Duration

How long a resource waits on a persistently-resting pool before failing Resting.

probe_concurrency: usize

How many exits are health-probed concurrently.

slim_timeout: Duration

Per-request timeout for a slim HTTP fetch.

slim_connect_timeout: Duration

Connect timeout for a slim HTTP fetch.

redirect_mismatch_backoff_base: Duration

Base of the escalating domain-level backoff a confirmed structural redirect mismatch earns (see REDIRECT_MISMATCH_BACKOFF_BASE’s docs).

redirect_mismatch_backoff_max: Duration

Ceiling of the domain-level redirect-mismatch backoff.
