Rust exact leaf and cache efficiency checks

Exact leaf work avoidance and early cache depth gating improve completed-search latency; shared full-key tables may reduce duplicate worker work within bounded memory.

Theories tested
Primary metric
Bit-exact leaf and legal root-column values; descriptive paired wall and process CPU latency on identical constructed public roots
Secondary metrics
  • move/leaf calls, nodes, cache hits
  • allocated table bytes, peak process RSS
  • five alternating-order repeats; microbenchmark CPU and search time
  • private gates 1,2,3; capacities 1024,16384,262144; shared/private tables at equal total entries; 1,2,4 workers
Statistical unit
root
Uncertainty method
Report every repeat, median and min/max of paired ratios. Constructed roots are mechanics diagnostics; no game confidence interval or population claim.
Data role

Seed leases
none recorded
Whole-origin split
yes
Reuse disclosure
CHECK only: constructed public boards and existing Rust unit/parity fixture domains 0xa5276000-0xa5277fff already opened by the original engine check. No new gameplay cohort, protected/final data, or strength evaluation.
Pass criteria
  1. Zero f64 value-bit, selected-action, event or trace mismatches on paired completed-depth checks and existing tests. Cache choices may change realized work, and bounded-work fallback parity is claimed only for identical cache configuration.
  2. Retain exact leaf and early depth-gate changes when the five-repeat median completed-search speed ratio exceeds 1.03; otherwise record negative and retain as optional or revert.
  3. Shared cache compares full keys under synchronized nonblocking access, has bounded allocation and decision/configuration scope, and never exposes an incomplete value; keep opt-in unless all measured configurations favor it.
  4. Run Cargo release checks, native/TypeScript parity, research validation and web build/MDX/figure tests; disclose pre-existing missing historical artifacts.
On pass
Publish CHECK engineering result and reviewable PR only; no strength claim or automatic cloud run.
On fail
Retain negative/partial measurements and reject exact failing configuration; open no cohort.

Stop conditions
  1. Stop on any semantic mismatch and investigate before timing that arm.
  2. Stop individual benchmark process after 120 seconds; total benchmark budget 1800 seconds; record partial arms without silently changing configuration.
  3. One benchmark process at a time, no agent builds/tests during timed batches; fixed 1/2/4 worker sweep, no nested pools. Host is an interactive macOS workstation without hard affinity/isolation; report timings as shared-host diagnostics, never exclusive-machine throughput.
  4. Stop at 4 GiB requested engine memory; no system settings, cloud resources or new game seeds.

Avoiding mathematically unused leaf work preserved exact values and reduced completed D4/S7 search from 12.052394167 to 11.257799041 median seconds per six constructed roots (1.07058x ratio of medians; 1.06786x paired median), with 4.4384% fewer retired instructions over five repeats. The leaf microbatch improved 1.16989x with 10.6541% fewer instructions. Unpack simplification had no credible independent speed gain. Capacity/depth sweeps quantify memory versus recomputation. A bounded full-key shared table saves work at multiple workers but offers only modest latency gains and loses slightly at one worker, so private gate 1 remains default. This is a local CHECK engineering result on an interactive M3 Pro, not stronger-play evidence.

What it had to pass
  • ✓Zero exact value/action/feature/trace mismatches on completed checks. — observed: All 210 timed processes completed with matching values/actions; 33,740 × 18 raw leaf feature bits and 1,296 unpack cases pass. 40 Rust tests and strict-FP C++/TypeScript gates pass. Default-contraction failures were investigated and retained before timing.
  • ✓Five-repeat median completed-search ratio exceeds 1.03 for retained default package. — observed: D4/S7/gate1/cap16384 ratio of medians 1.0705817472; median paired ratio 1.0678604115, range 1.0582717724–1.1158545109. Median retired instructions fell 4.4384334782%. Leaf-only ablation also passes. Standalone unpack gain is not supported.
  • ✓Bounded synchronized full-key shared cache; retain opt-in unless every measured setting favors it. — observed: Full-key/depth/collision/contention/lifetime and resource tests pass. One worker shared is slightly slower; four-worker gate 1 saves 5.17943% median work and 3.91020% instructions, with 1.0301088 ratio of latency medians. Private/gate1 defaults remain.
  • ✓Five repeats of all registered arms within 1800 seconds and four timing workers. — observed: 210 completed processes; 1762.724547493 cumulative measured-process seconds; no timeout or semantic mismatch. Every raw stdout/stderr and measured source snapshot is retained.
  • –Repository/native/TypeScript/Rust and web validation pass or existing limitations are disclosed. — observed: 40 Rust tests, native/TypeScript gates, 6 research tests, 70 web tests, production build, typecheck, lint, MDX, frontmatter and figure/style/metadata checks pass. Absent-data rendering: 8/8. Desktop visual checks pass. Aggregate make -k test reports the same 96 pre-existing missing artifact errors; separate chart suite is 63/64 due to an unchanged stale evolution fixture expectation. Route sweep: 727/728; /compete lacks local GitHub authentication configuration.

Limitations
  • Constructed six-root mechanics workload, five repeats per arm; no gameplay-strength cohort, score confidence interval, protected/final seed, or million-point claim.
  • Interactive Apple M3 Pro/macOS workstation with Chrome, WindowServer and Codex active; no affinity, exclusive CPU lease, thermal/frequency trace or maximum-throughput claim. Later capacity repeats experienced desktop contention; every repeat and min/max is retained.
  • Sequential search timers exclude table allocation; parallel decision timers include planning, initialization, execution and reduction. Process counters include the harness. CPU seconds print to 0.01 seconds; tiny unpack timings are noisy.
  • Exact bits are checked under the existing canonical search order. This preserves existing floating accumulation/tie behavior, not a new guarantee for independently evaluated raw mirrored boards.
  • Shared hits/work depend on scheduling. Equal completed-depth values do not imply identical stopping depths or fallback actions at a fixed work budget across cache configurations.
  • Tables compare complete keys and publish completed values under synchronized nonblocking access. Shared storage is fresh per decision/parameter/leaf definition, not reusable across games or changing evaluators.
  • Equal-entry worker comparisons use 65,536 total entries, split zero internal plies, depth 4/strata 7 and 1/2/4 workers. Shared projection includes 40,960 extra bytes for stripes/runtime locks; allocator metadata and thread stacks are excluded from table estimates. Peak process RSS is separately measured.
  • The standalone unpack rewrite produced no credible speedup or useful instruction reduction. The leaf-only ablation accounts for most combined improvement; early hash gating has no separately isolated performance claim.
  • The existing C++ reference built with default arm64 floating contraction differed on one of six leaf/root fixtures for both baseline and candidate. Both were corrected by compiling the reference with -ffp-contract=off before final gates and candidate timing; original failed checks are retained.
  • make -k test passed native/TypeScript checks but aggregate research validation reports 96 pre-existing missing historical artifacts. Those records/hashes were not rewritten. Web build, typecheck, lint and 70 web tests pass. The separate chart library has 63 passes and one pre-existing stale evolution-snapshot expectation; both its test and fixture match HEAD. The full route sweep passes 727/728; /compete lacks local GitHub authentication configuration. Both Rust pages/cards, charts and diagram pass desktop visual checks; absent-data rendering passes eight checks.
  • This source adds table_scope to ParallelConfig. External callers using exhaustive struct literals must add the field or use Default; default private scope and depth threshold 1 are preserved.
