Crawl Policy

crawl is the policy for bounded site traversal.

crawl:
  mode: contract_focus
  budget:
    max_pages: 25
    max_depth: 2
  scheduler:
    max_workers: 3
    per_host_concurrency: 1
    politeness_delay: 1.0
  safety:
    respect_robots: true
    allow_redirects: false
    allow_cross_domain: false

Top-level fields

Field	Type	Default	Description
`mode`	enum	`contract_focus`	Crawl mode: `seed_hunt`, `contract_focus`, `structure_guarded`, or `explorer`.
`budget`	object	see below	Page, depth, attempt, and session limits.
`scheduler`	object	see below	Worker, per-host, politeness, timeout, and retry settings.
`safety`	object	see below	Robots, redirects, host allow/deny, path blocking.
`escalation`	object	default-deny	Paid/model escalation gates.
`target_contracts`	list	`[]`	Contracts the crawl is trying to find.
`scrape_contracts`	boolean or list	`false`	Whether to scrape representative URLs after crawl.
`scrape_url_limit_per_contract`	integer	`1`	Representative scrape cap.
`fetcher_type`	enum	`auto`	Fetch tier for crawl page acquisition.

Budget

Field	Default	Description
`max_pages`	`1`	Maximum successful pages.
`max_depth`	`0`	Link depth from seeds.
`max_attempts`	`null`	Optional cap including failures and policy-blocked URLs.
`max_pages_per_host`	`null`	Optional host-level page cap.
`crawl_session_id`	`null`	Checkpoint/session id when persistence is enabled.

Scheduler

Field	Default	Description
`max_workers`	`1`	Total concurrent crawl workers.
`per_host_concurrency`	`1`	Concurrent workers per host.
`politeness_delay`	`1.0`	Minimum delay between same-host fetches.
`fetch_timeout_seconds`	`15.0`	Fetch timeout for crawl pages.
`max_fetch_retries`	`2`	Fetch retry cap.

Safety

Field	Default	Description
`respect_robots`	`true`	Honor robots.txt.
`allow_redirects`	`false`	Allow redirects during crawl fetches.
`allow_cross_domain`	`false`	Permit crawling across domains.
`allowed_hosts`	`[]`	Explicit host allowlist. If empty, seeds derive allowed hosts.
`denied_hosts`	`[]`	Explicit host denylist.
`blocked_path_prefixes`	`[]`	Path prefixes to skip before fetch.

Escalation

Escalation is default-deny.
