Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This PR adds residency feasibility tests and recorded evidence, but the current version still has a Windows compilation failure and several validation paths that can accept incomplete, mismatched, or misleading results. Merge readiness therefore requires fixing these bounded correctness issues or obtaining explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@test/cpp/test_residency_prototype_task014.cpp`:
- Around line 469-490: Align the platform-specific emit_rows outputs with the
fixed EXPECTED_ROW_KEYS closure: in
test/cpp/test_residency_prototype_task014.cpp lines 469-490, add
containment.escape_detected as deferred; at lines 1253-1256, add all eight
listed containment-related keys as deferred. In
test/residency/prototypes/test_task014_durable_process_public_seam.py lines
876-881, retain the exact closure assertion and verify it passes on Windows,
macOS, and Linux.
- Line 34: Wrap the probe helper declarations and definitions in
test_residency_prototype_task014.cpp with namespace lemon containing the
existing anonymous namespace, while keeping main or wmain at global scope.
- Around line 1-13: Add the standard <iterator> header to the include list of
test_residency_prototype_task014.cpp so read_windows_file and read_posix_file
can use std::istreambuf_iterator without relying on transitive includes.
In `@test/cpp/test_residency_prototype_task015.cpp`:
- Around line 1047-1129: Wrap the Linux-only helpers hatchery_device_matches,
parse_memavailable, parse_current_cgroup_memory, and host_memory_is_observed in
an __linux__ compile-time guard, keeping their existing implementations only on
Linux. Provide the non-Linux branch of probe_native_hatchery_profile with the
unavailable profile, so Windows and macOS builds do not compile the sysfs/procfs
probes.
In `@test/residency/prototypes/result_contract.py`:
- Around line 61-79: Update the _fail function annotation to use typing.NoReturn
instead of None, adding the necessary import, so static analysis recognizes that
every call terminates execution and correctly handles _parse and other helpers.
In `@test/residency/prototypes/test_task014_durable_process_public_seam.py`:
- Around line 659-662: Update the adversary-path compile invocation in the test
around run_native_probe to use the same compiler selection as run_native_probe,
honoring the recorded compiler observation or CXX instead of hardcoding "c++";
preserve check=True and the existing compiler_command arguments.
In `@test/residency/prototypes/test_task015_hatchery_attribution_public_seam.py`:
- Around line 137-231: Move the shared helpers require, compiler_command,
normalized_architecture, compiler_version, and parse_json_object into
result_contract.py, then update this task’s callers to use them while supplying
task-specific error messages or local wrappers as needed. Preserve TASK-018
labels and failure text, and keep FAILURE-dependent fail_unavailable behavior
local to the task.
- Around line 664-691: Bound the subprocess operations in the compiler test by
adding an explicit timeout to the compile invocation near compiler_command and
to the compiler_version query, matching the existing bounded probe execution
while preserving current command arguments and error handling.
Apply the same fix in
`@test/residency/prototypes/test_task016_llamacpp_rocm_sizing_public_seam.py`
around lines 376 - 390: Same unbounded compiler version and compilation
subprocesses.
Apply the same fix in
`@test/residency/prototypes/test_task017_llamacpp_soft_release_public_seam.py`
around lines 1200 - 1219: Same unbounded compiler version and compilation
subprocesses.
In `@test/residency/prototypes/test_task017_llamacpp_soft_release_public_seam.py`:
- Around line 1484-1567: Remove the redundant literal row-value assertions from
require_fail_closed_semantics and the checks continuing through the affected
later sections, since require_exact_probe_rows already validates the complete
expected row list. Delete the NEGATIVE_OUTPUT_ROWS loop, repeated negative-key
checks, dimension_rows, presence_rows, and equivalent disposition, unsupported,
selected-fallback, and synthetic literal checks. Preserve derived arithmetic and
cross-family invariants, including require_physical_semantics, generation
increments, and ledger-to-physical equality checks.
- Around line 1187-1198: The TASK-017 toolchain binding is unstable because it
compares the full compiler version while CI installs an unpinned compiler.
Update the compiler-version validation around compiler_version and the recorded
observation to compare an intentional stable version prefix, or otherwise pin
the CI compiler image/package; preserve platform-specific compiler selection and
the existing command-generation flow.
- Around line 497-548: Extract the duplicated compiler_command,
normalized_architecture, compiler_version, current_platform, and
parse_probe_output helpers from the prototype tests into a dedicated shared
utilities module, then update callers to use it. Keep load_result_contract in
the test layer because it depends on fail_unavailable, and do not reuse
result_contract.py’s private parsing helpers unchanged.
