HERTZ TREE-KILL MEASUREMENT PREDICATE

(a) SCAN ROOT: crates/spt/tests/*.rs only; non-recursive top-level Rust integration-test binaries. Excluded crates/spt-daemon/tests, unit-test modules under src, scripts, and nested crates/spt/tests/common/mod.rs.

(b) TREE KILL: a file contains both the literal Rust constructor Command::new("taskkill") and a literal argument "/T". File-level lexical predicate; one file counts once. Result: 31 files.

(c) BREADCRUMB-DRIVEN: narrower, manually confirmed data flow: the test reads <isolated SPT_HOME>/daemon.pid, parses that file value as u32, and passes that pid to the local taskkill /F /T helper/site. No other pid-file names qualified under this predicate. Result: 6 files.
- crates/spt/tests/worker_lifecycle_e2e.rs — daemon.pid
- crates/spt/tests/ready_resume_ledger_e2e.rs — daemon.pid
- crates/spt/tests/job_escape_e2e.rs — daemon.pid
- crates/spt/tests/contract_e2e.rs — daemon.pid
- crates/spt/tests/activity_link_push_e2e.rs — daemon.pid
- crates/spt/tests/worker_visibility_e2e.rs — daemon.pid

(d) CAVEAT: this measurement makes no claim about other crates or other pid breadcrumbs (brain.ready JSON, shell.pid, resume.pid, ad-hoc temp pidfiles). Todlando’s 42/19 can therefore be a correct superset; list comparison is required before a systemic total is stated.
