Own operation results and exact rejections in withVerifierCleanup, including
undefined, null and independent cleanup failures. Remove the optional-primary
cleanup contract and migrate every caller, preserving returns, annotations,
signal restoration and dependent cleanup order.
Make Frida/JEB reporters fail on reasonless rejections and retain JEB fixture
files while provider cleanup is incomplete. Own the nested packaged WASM
verifier and expose its composite process/root cleanup capability for retry.
Update runnable docs and isolated fixture dependencies.
Validation: 547 focused cases in 20 files, eight isolated boundary unit checks,
static/build/docs/discovery gates and duplication check (3.58%). Node process,
SDK and descriptor cleanup are exercised; provider and packaging results in
orchestration tests are simulated. Pack/install subprocess ownership remains
with the existing shared package runner outside the nested-command change.
Bind runtime and descriptor cleanup to exact retry leases and retain command supervisors until stop is confirmed. Preserve primary errors, partial Evidence and finalization cancellation reasons.
Validate with 88 focused tests, official WABT 1.0.42 CLI/MCP verifier (51 cases), build, static and documentation checks. Command stop failures use controlled source seams; real permission failures and target execution are unverified.
