What it is for

Thin bounded wrapper around nmap -oX -: cited Observations from a port/service scan, no verdicts.

XML shape verified live against a real nmap -oX - -p 22,80,443 127.0.0.1 run on this machine (not assumed). Notably: nmap emits a preliminary <hosthint> element (same child shape as <host>, no port results) during a scan before the final <host> — this parser only builds records from real <host> elements, <hosthint> is explicitly skipped, not merely ignored-by-omission.

quick-xml's Reader/event-loop idiom here matches the existing consumer in this workspace (crates/operations/test-results-ingest/src/junit.rs) rather than introducing a different XML-parsing style.

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

`crate root`

Item	What it is
`pub enum NetScanError`	Every way a scan can fail.
`NetScanError :: fn from(e : quick_xml::Error) -> Self`	—
`NetScanError :: fn from(e : quick_xml::events::attributes::AttrError) -> Self`	—
`pub struct NmapPort`	One `<port>` result under a `<host>`.
`pub struct NmapHost`	One `<host>` result — never built from `<hosthint>`.
`fn parse_nmap_xml(xml : & str) -> Result <Vec <NmapHost>, NetScanError>`	Parse `nmap -oX -` XML into one `NmapHost` per real `<host>` (never `<hosthint>`)
`fn to_observations(hosts : & NmapHost) -> Vec <Observation>`	Lift parsed hosts into cited Observations, one per port (or one per host if it has no ports — e.g
`async fn scan(nmap_bin : impl Into <PathBuf>, args : & & str, limits : ExecLimits,) -> Result <Vec <Observation>, NetScanError>`	Run `nmap -oX - <args>` and cite each discovered host/port

No pub use re-exports: every item above is declared in this crate.

Boundary

Reaches into foundation, infrastructure.

Shares tier operations with 40 other crates: operations-approval-workflow, operations-assessments, operations-block-imaging, operations-boot-media, operations-browser-agent-worker, operations-camera-discovery, operations-camera-liveview, operations-camera-registry, … (40 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._
