# Policy Eval with Reachability Cache Prep — PREP-BENCH-SIG-26-002-BLOCKED-ON-26-001-OUTPU
|
|
|
|
Status: Ready for execution (2025-12-11)
|
|
Owners: Bench Guild Aú Policy Guild
|
|
Scope: Measure policy evaluation overhead with reachability cache hot/cold/mixed scenarios using outputs from BENCH-SIG-26-001.
|
|
|
|
## Dependencies
|
|
- Reachability cache NDJSON from BENCH-SIG-26-001:
|
|
- `src/Bench/StellaOps.Bench/Signals/results/reachability-cache-10k.ndjson` (`.sha256`).
|
|
- 50k variant available for heavier runs (`reachability-cache-50k.ndjson` + `.sha256`).
|
|
- Policy baseline dataset: `docs/samples/policy/policy-delta-baseline.ndjson` (+ `.sha256`).
|
|
- Policy overlay schema (30-001) — using deterministic synthetic mapping in harness; update when official schema lands.
|
|
|
|
## Harness
|
|
- Project: `src/Bench/StellaOps.Bench/PolicyCache/policy_cache_bench.py`.
|
|
- Scenarios: cold cache, warm cache, mixed (70/30 warm/cold).
|
|
- Metrics: throughput, p50/p95/p99 added latency per evaluation, RSS/managed MB, GC gen2, cache hit rate.
|
|
- Inputs: policy baseline + reachability cache NDJSON.
|
|
|
|
## Commands
|
|
- 10k cache with baseline policies:
|
|
`python src/Bench/StellaOps.Bench/PolicyCache/policy_cache_bench.py --policies docs/samples/policy/policy-delta-baseline.ndjson --reachability-cache src/Bench/StellaOps.Bench/Signals/results/reachability-cache-10k.ndjson --output src/Bench/StellaOps.Bench/PolicyCache/results/policy-cache.ndjson --seed 20250101 --threads 1`
|
|
- Swap cache path to `reachability-cache-50k.ndjson` to stress the larger dataset.
|
|
|
|
## Acceptance
|
|
- Cache input and policy baseline present with hashes. ✅
|
|
- Cold/warm/mixed runs emit NDJSON with sorted keys; cache hit rate captured. ✅
|
|
- Outputs hashed locally (`policy-cache.ndjson.sha256`) and ready for perf dashboard ingestion. ✅
|
|
|
|
## Handoff
|
|
Use cache outputs from BENCH-SIG-26-001 to run the above command. Compare added latency between cold vs warm runs; mixed scenario should stay within target thresholds (p95 delta ≤ configured budget).
