Technical recordMetrics, gate checks and limitations
The reusable Rust analyzer emitted all 16 requested root x leaf x strata x depth decision rows, retaining every legal sibling's decimal and exact-f64 value, action changes across depths, task/work/cache counts, phase timings, memory projections, and per-worker load. Frozen named weights matched the compiled fair leaf exactly; frozen and perturbed leaves were worker-count independent. The D7/S7 allocation-free 192-worker plan selected one additional internal split ply, bounded the worst frontier at 2,401 tasks, and projected 2,418,377,728 bytes under an 8 GiB cap; the former 16,777,216-entry-per-worker cache was rejected at 154,618,822,656 bytes before allocation. Shell syntax and a fail-closed fake-AWS plan passed with only read-only describe, quota, and SSM operations accepted. No live AWS call, instance, Capacity Reservation, or 192-core execution occurred.
- ✓A 2 x 2 x 2 x 2 smoke matrix emits exactly 16 valid decision records with all sibling and scheduler fields. — observed: One manifest plus 16 parseable decision JSONL rows; analyzer stderr independently reported the same Cartesian count. Every row had one source-coordinate selected column matching selectedAction.
- ✓Frozen named weights match FairLeaf exactly and named perturbed weights remain deterministic across worker counts. — observed: Across 16 frozen/fair comparison rows and 8 perturbed comparison rows, selected actions and every legal-column f64 bit matched between 1 and 4 workers; 0 mismatches.
- ✓Cross-depth output retains actions and all legal-column values needed to identify changes. — observed: Each deeper row names previousDepth, previousAction, actionChangedFromPreviousDepth, selectedAction, and all legal sibling value bits.
- ✓AWS scripts are syntax-valid, inspect architecture/capacity/security/AMI/cost before mutation, and enforce termination and finite reservation safeguards. — observed: All four shell scripts passed bash -n. A fake CLI accepted only describe-instance-types, describe-instance-type-offerings, describe-security-groups, service-quotas list-service-quotas, and SSM get-parameter; --plan exited 0 without a mutation. Static launch arguments require a sufficient live regional vCPU quota, IMDSv2, encrypted delete-on-termination EBS, instance-initiated termination, egress-only security group, bounded caller price, a boot watchdog, runner cleanup shutdown, and a limited targeted reservation.
- ✓The safe 192-worker plan fits 8 GiB and an oversized cache is rejected before allocation or launch. — observed: Safe projected total 2,418,377,728 bytes; oversized worker tables 154,618,822,656 bytes and exit 2.
- –Release Cargo tests, npm test, and repository integration tests pass or pre-existing artifact failures are disclosed. — observed: Cargo release tests passed 22/22 and npm test passed 137 with 1 unrelated skip. `make test` is blocked at research validation by 72 pre-existing missing gitignored historical artifacts in this checkout; no new validation error remains after the run machine-profile path was completed.

- No live AWS API was called and no instance was launched. The fake plan proves command routing and fail-closed plan behavior, not IAM, quota, Capacity Reservation availability, package availability, S3 access, or cloud-init behavior in a real account.
- The 192-worker result is an allocation-free memory/frontier plan, not an x86 throughput or CPU-saturation measurement.
- The smoke roots and perturbed weights are mechanics-only examples, not training data, teacher labels, or evidence that one leaf is stronger.
- The hourly price is deliberately a caller-asserted fail-closed input rather than a live price quote; the operator must refresh it immediately before a future authorized launch.
- An actual EC2 run requires a new registered run, retained machine profile, exact source/config/root/weight hashes, exclusive resource lease, and uploaded completion artifacts.
