 phi-redact v7 is essentially tied with Desert Ant's English composite at half
 the parameters and half the on-device footprint.
 
+### Inference latency
+
+Measured 2026-10-03 against the live demo (corytrimm.com/phi-redact): the
+same 15-template typing-length corpus as `evals/latency-bench/bench.py`,
+15 templates × 10 cycles = 150 redactions, timed from the page's own
+per-redaction readout — TypeScript rules scan + ONNX detect + merge +
+placeholders, end to end, onnxruntime-web WASM (Chromium on Linux).
+
+| Input | p50 | p95 | p99 |
+|---|---|---|---|
+| Chat-length (150 samples) | **6.0 ms** | 8.0 ms | 9.0 ms |
+| Long text (3,959 chars, 139 entities) | 572 ms | — | — |
+
+Model load: 0.5 s cached, 4.4 s cold (11.3 MB int8 ONNX + runtime download).
+
+Caveats: the model was cached for this run; browser version and hardware
+details were not obtainable from the measurement setup (Linux VM, not a
+phone); readout resolution is whole milliseconds. Not a head-to-head with
+any vendor's published number — different hardware, corpus, and setup.
+Methodology travels with the number; see `evals/latency-bench/`.
+
+### Synthetic redaction eval (164 cases)
+
+`evals/synthetic-164/` carries a 164-case synthetic redaction test set, the
+scoring harness, and v7's results: **0.812 full-value recall** (term recall
+0.615, precision 0.698, clean-case FP rate 0.120). Perfect 1.000 on
+BANK_ACCOUNT, CREDIT_CARD, DRIVERS_LICENSE, EMAIL, PHONE, ROUTING_NUMBER;
+weak on NAME (0.347) and ADDRESS (0.333). See the directory README for
+methodology and the taxonomy note.
