The corrected source aed07176ab453b981d5f9c76e504c531f6dd7f42 passed 26 focused scenario-layout tests, all 471 executed core tests (one ignored scaling probe; 44 result summaries), and strict Clippy. The focused tests overlap the full suite; do not add their counts. This archive preserves the two preceding failures as well as the successful attempt.

Raw attempt	Source	Observed result
attempt1-ecc	`ecc49e0417`	Listing command failed to compile: E0061, missing `EditContext`; no test acceptance.
attempt2-9245	`9245f8d23e`	Listed 80 tests, including 26 selected tests. Execution then passed 8 and failed 18 at incompatible scenario-viewpoint fixture setup. Listing was not a passing execution.
attempt3-aed	`aed07176ab`	Focused 26 passed; full suite 471 passed, 0 failed, 1 ignored; strict Clippy exit 0.

Commands, exact timestamps, terminal exit codes, original scripts and logs are in each attempt directory. Successful commands were:

cargo test -p oa-core --lib --locked --offline -- scenario_layout --nocapture --test-threads=1
cargo test -p oa-core --all-targets --locked --offline
cargo clippy -p oa-core --all-targets --locked --offline -- -D warnings

The original runner used the isolated Scenario checkout and target directory recorded in its scripts. All three attempts have identical before/after membership, sizes and SHA-256 for their respective 584 input files. Archival verification also compared all 584 current frozen source files with attempt3's manifest. All 24 copied raw files matched their originals byte for byte; verification.json records this check. report.json inventories this archive by size and SHA-256, excluding itself. Raw paths and historical status fields remain unchanged.

The ignored test is inheritance_chain_validation_scaling_probe, explicitly opt-in. These are Windows core gates, not desktop/native acceptance, an offscreen WGPU gate, combined-659 acceptance, or completion of free scenario editing. Archival work reran no compiler or tests. The failed attempts remain nonacceptance evidence.
