Conversation

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe pull request adds a Gradle benchmark module with shared simulations and raw FTC, multithreaded raw, SolversLib, and Synapse runners. It adds measurement, comparison, and verification tools, a checked-in baseline, and benchmark documentation. It also adds a separate plan for a Synapse website and agent skill.

Merge Risk: 🟡 Moderate · up to The suite can report misleading performance results or a successful run despite failing its required ladder, while the accompanying website plan is not yet executable as written. These issues should be resolved before relying on the benchmark or implementing the plan. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The benchmark is separate from the production library and requires a local command to run. Its main risk is that result files and verification outcomes can be misread as evidence of a successful run, not that it exposes a new production security boundary. Retained concerns

Ladder S0-S3 of raw/rawmt/solverslib/synapse styles on a shared simulated robot (SimPlant), with input-to-actuation latency, per-task rate/jitter, tracking RMSE, loop/scheduler throughput, allocation, and a micro layer of Synapse dispatch primitives. Harness gates: framework class provenance, mock budget <=5%, no reimplemented schedulers/buses in style packages. compare subcommand with 0/1/2 exit codes detects regressions against the committed results/baseline.json (two --full forks, merged median).

Compare: missing latest metrics (latency/task/tracking) now go to the missing list (exit 2) instead of being treated as improvements. Main: stop and join the runner before taking metric snapshots so the single-writer Hist cannot be mutated while periodSnapshot copies it. MicroBench: contention bench samples 8-40 intervals into a Hist so p50 and p99 are real percentiles, not fabricated from one average. Scenario: hasServo() restricted to S1 (S1 is the only scenario whose runners implement the servo) so StimulusTimeline no longer injects unimplemented g1/x traffic for S2/S3. SimCamera/SynapseS3: camera frames are copied before the async publish to the camera/frame topic, so ring reuse cannot corrupt vision work running on the callback pool. SolversS1/SolversS2: right stick normalized (-getRightY()), matching SolversS3 and the raw/synapse styles for matched-stick tank drive. plan: website/skill plan rewritten so the per-page .md mirrors are pre-rendered and served by Nginx via Accept content negotiation (static Astro output cannot negotiate at request time); Link headers are emitted via Nginx add_header (sub_filter only rewrites response bodies); Docker build context is the repository root so CHANGELOG.md is available without a hard-coded host path; both @SubscribedTo skill examples use the required named topic attribute. baseline.json regenerated with run --full --forks 2 (merged median) to reflect the corrected measurement semantics.

Balance style order across rounds.
Main.java:175-187 groups all rounds by style. The fairness rules require identical workloads and document warmup, medians, and forks, but they do not require a specific execution order. This fixed order can associate order-dependent JVM or CPU state with a style. The baseline and comparison code provide no counterbalanced run or order data that demonstrates a material bias, so this is a recommended benchmark improvement, not a major defect.
Interleave styles across rounds, use the configured seed to vary the order, and record the executed order in env.

- Fork branch now prints ladder shape after writing outputs so the merged ladder check is visible alongside the single-run path. - filterStyles rejects any requested style that isn't available for the scenario, preventing silent zero-pair runs.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winMake the ladder result part of the run exit status.
The ladder is an acceptance criterion, but
printLadderonly prints failures.gateExitchecks onlygates.ok. A failed comparison, or a missing required pair that currently skips the comparison, can therefore return success when the other gates pass. Enforce this for runs that request the full ladder; keep intentional subset runs non-gating.Suggested fix
- printLadder(doc); - return gateExit(doc); + boolean ladderOk = ladderRequested(cfg) ? printLadder(doc) : true; + return gateExit(doc, ladderOk); - private static int gateExit(Map<String, Object> doc) { + private static int gateExit(Map<String, Object> doc, boolean ladderOk) { ... - return Boolean.TRUE.equals(ok) ? Compare.EXIT_OK : Compare.EXIT_REGRESSION; + return Boolean.TRUE.equals(ok) && ladderOk + ? Compare.EXIT_OK : Compare.EXIT_REGRESSION; } - private static void printLadder(Map<String, Object> doc) { + private static boolean printLadder(Map<String, Object> doc) { ... - boolean ok = true; + boolean ok = s0Raw != null && s0Syn != null + && s3Syn != null && s3Raw != null && s3Sol != null; ... + return ok; }Apply the same

feat(benchmarks): add idiomatic FTC code benchmark suite
Ladder S0-S3 of raw/rawmt/solverslib/synapse styles on a shared simulated
robot (SimPlant), with input-to-actuation latency, per-task rate/jitter,
tracking RMSE, loop/scheduler throughput, allocation, and a micro layer of
Synapse dispatch primitives. Harness gates: framework class provenance,
mock budget <=5%, no reimplemented schedulers/buses in style packages.
compare subcommand with 0/1/2 exit codes detects regressions against the
committed results/baseline.json (two --full forks, merged median).
