## Verdict

Fresh Visual Studio 18 2026/MSVC x64 Debug configuration, a clean full rebuild,
the exact Step 25 configure/build commands, nonzero JSON discovery, the feature-label
CTest run, and the full CTest run all passed. CTest discovered the expected 83 tests
and both executed suites passed 83/83. The clean rebuild emitted no compiler or linker
warning line, and generated FESA product projects retain Level 4 plus warnings-as-errors.

The build/test gate therefore passes for handoff to Step 26 Reference Verification.
This verdict does not approve reference tolerance, physics sanity, or release readiness.

### Dependency Revisions

| dependency | resolved revision or version | evidence |
| --- | --- | --- |
| GoogleTest | `04ee1b4f2aefdffb0135d7cf2a2c519fe50dabe4` | clean `C:/git/googletest` checkout HEAD |
| Intel oneMKL | `2026.1.0` | `MKLConfigVersion.cmake`; configure reported `MKL_VERSION: 2026.1.0`, dynamic ILP64, Intel threading |
| Intel oneTBB | `2023.1.0` | `TBBConfigVersion.cmake` from the configured `2023.1` package |
| HDF5 | `2.1.1` | `hdf5-config-version.cmake` from the configured `2.1.1` package |

## Freshness and Configuration Resolution

The ignored generated build tree already existed. Fresh evidence was obtained without
reusing its cache or products by running CMake `--fresh` with the generator explicitly
fixed to Visual Studio 18 2026, then running the generated `clean` target before the
full build. The literal no-`--fresh`, no-`-G` configure command from Step 25 was then
run against that resolved VS18 cache and followed by the literal build, discovery,
feature-label, and full-test commands.

Post-configure metadata recorded:

- `CMAKE_GENERATOR=Visual Studio 18 2026`
- `CMAKE_GENERATOR_PLATFORM=x64`
- `CMAKE_CXX_COMPILER_ID=MSVC`
- `CMAKE_CXX_COMPILER_VERSION=19.51.36252.0`
- `CMAKE_CXX_COMPILER_ARCHITECTURE_ID=x64`

An initial post-clean discovery/feature/full smoke was also run before the literal
configure replay: discovery exit 0 in `0.068 s` with 83 tests, feature-label CTest
exit 0 in `4.244 s` with 83/83, and full CTest exit 0 in `4.011 s` with 83/83.
Rows 4 through 8 are the final canonical Step 25 acceptance chain.

| `unit` | 73 |
| `integration` | 5 |
| `reference` | 5 |

### Suite Inventory and Step Trace

| implementation Step | CTest suite or suites | count | cumulative count | Step 7-24 report evidence audit |
| ---: | --- | ---: | ---: | --- |
| 7 | `BuildInfo` | 2 | 2 | pass |

| 24 | `LinearStaticCli` (5), `ReferenceComparisonContract` (4), `B33ReferenceComparison` (1) | 10 | 83 | pass |

The JSON inventory contains every exact test name registered by GoogleTest discovery.
No duplicate CTest name was observed; the label partition is exactly 73 unit + 5
integration + 5 reference = 83.

## Step 7-24 Implementation Evidence Audit

The cumulative implementation report was checked block-by-block against the implementation
plan and the phase index summaries. All 18 Step blocks are present and each records:

- its matching `TASK-07` through `TASK-24`, `status: completed`, changed files,
  requirement IDs, and test IDs;
- at least one implementation-owned nonzero RED command with the expected missing API
  or named behavioral failure;
- a zero-exit GREEN build/test for the Step's targeted CTest suite;
- zero-exit MSVC x64 configure/build, nonzero JSON discovery, and zero-failure full CTest;
- `/W4 /WX` or equivalent generated warning-policy evidence and reference-tree
  immutability evidence.

Step 20 and Step 22 additionally retain valid behavioral RED/GREEN correction evidence.
Step 23 records its environment link incident separately from the valid missing-API RED,
so the environment incident was not counted as TDD evidence. The cumulative counts in the
implementation report and the Step 7-24 phase summaries progress exactly to the freshly
discovered 83-test inventory above.

The implementation report's cumulative header still says `in-progress`; the audited
step-local evidence contract and phase index nevertheless mark every implementation Step
7-24 `completed`. This stale aggregate header is not a missing Step block, missing test,
or failed build/test gate and was not modified by the independent executor.

## `/W4 /WX` and Warning Audit

- `src/fesa/CMakeLists.txt` applies `/W4 /WX` privately to `fesa_solver` and `fesa_cli`.
- Generated `fesa_solver.vcxproj` and `fesa_cli.vcxproj` contain
  `<WarningLevel>Level4</WarningLevel>` and
  `<TreatWarningAsError>true</TreatWarningAsError>` for Debug and the other generated
  configurations.
- The clean 74.713-second build recompiled the product and all test translation units;
  its compiler/linker warning scan found `0` lines.
- The exact post-configure build also exited 0 and found `0` warning lines.

Result: no product warning was emitted, and any MSVC product warning would have failed
the build under `/WX`.

## Reference Read-Only Audit

The following SHA-256 values were identical before and after all configure/build/test
commands, while both reference diff checks exited 0 and both reference status checks
were empty:

| exact approved legacy path | SHA-256 |
| --- | --- |
| `reference/cantilever beam/cantilever beam.inp` | `E406EA9560321B791DB829E03BD24593B9875E0195D35B86BD931EDA122EF3` |
| `reference/cantilever beam/cantilever beam displacements.csv` | `7B3312FBC8848E81D9A0FD4FF2B56BC1954636A2C14B5C1CBB269CB9477D3C31` |
| `reference/cantilever beam/cantilever beam reactions.csv` | `BF30CDB0CD50106885DE14D63492737736C587426EBD787DE4F7EE6AA86DAA23` |
| `reference/cantilever beam/cantilever beam elemental forces.csv` | `E5E77FEC0FA9482AE018DBF296E74D396335C7C711BD2E9AA2315247A34290BA` |

## Failure Classification

- classification: `N/A`
- primary_failure: `N/A`
- first_failed_command: `N/A`
- evidence_tail: All required configure, build, discovery, feature-label, and full-test
  commands exited 0; no failed test exists.
- correction_handoff: `N/A`; no implementation-owned, environment, harness, or
  upstream-contract failure requires correction.

## Failed Test Inventory

None. Feature-label CTest and full CTest both passed 83/83.

## Handoff Recommendation

| target_agent | reason | required_input |
| --- | --- | --- |
| Reference Verification Agent | Step 25 build/test gate is `pass-for-reference-verification`. | This report, HEAD `400db19`, `.harness/build/tests/Debug/fesa_reference_tests.exe`, and the unchanged exact legacy bundle. |

The build-local Step 24 evidence exists at
`.harness/build/reference/cantilever-beam-b33/results.h5` and
`.harness/build/reference/cantilever-beam-b33/comparison.json`; the JSON is 128,118 bytes
with SHA-256
`258347AEA791D981AEA9B2BCAD85DE5344D4859ECA3692DC5E7AA01A848F8E0D`.
Step 26 must independently rerun and inspect the approved comparison evidence. Its
presence and CTest success here are not a reference-verification verdict.

## No-Change Assertion

- source_files_modified: `false`
- test_files_modified: `false`
- cmake_files_modified: `false`
- requirements_or_upstream_contracts_modified: `false`
- reference_artifacts_modified: `false`
- tolerance_policies_modified: `false`
- owned_report_modified: `true`
- phase_index_step25_modified: `true`
- notes: Before report/index creation the worktree was clean at the audited HEAD. Final
  scope validation is limited to this report and the Step 25 fields in the phase index.

## Open Issues

- None blocking Reference Verification.
- The implementation report aggregate `in-progress` header is noted above but does not
  contradict its 18 completed Step blocks, the phase index, or the fresh build/test result.
