infrastructure-host-forensics

Pure rule engine over already-parsed Windows registry/event-log records: cited observations for known physical-access compromise patterns, no verdicts

What it is for

Pure rule engine over already-parsed Windows registry/event-log records.

Each rule takes records produced by some other parser (out of scope here — see the crate README) and emits Observations: a fact plus the exact source citation, never a verdict. Interpretation ("is this malicious") happens outside the crate, by a human or an AI reading the citations — see docs/reference/STYLE.md in the workspace root for why that split is enforced.

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`

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

Boundary

Depends on no other workspace tier.

Shares tier infrastructure with 82 other crates: infrastructure-acquire, infrastructure-adapters-google-calendar, infrastructure-adapters-google-gmail, infrastructure-adapters-google-places, infrastructure-adapters-google-trends, infrastructure-adapters-shodan, infrastructure-adapters-yelp, infrastructure-agent, … (82 total).

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

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

Related capabilities

9 workspace crates depend on this one: infrastructure-bitlocker-forensics, infrastructure-firmware-forensics, infrastructure-hardware-forensics, infrastructure-memory-forensics, infrastructure-registry-forensics, infrastructure-write-blocker, operations-net-scan, operations-net-trace, tools-ir-triage.
