# Live DEV Redline performance

Measured 2026-10-05T21:37:40.770Z against `https://dev.api.bookcicle.com`. Service release: `RELEASE-20261005-3c0aa4ba1` (`3c0aa4ba12d28f0344cdb0a8fa1414d68d1f1597`). Native document release: `candidate/6abc81c4c`.

The small public DOCX is an agreement; the original resume-style label was corrected. Measurements and source hashes are unchanged.
Each qualified case has one excluded warmup and 7 measured successful requests. Thirty-request warm distributions and five/eight-request bursts are recorded separately. Authentication uses a fresh Creator Pro fixture with Stripe test-mode billing; cleanup is verified. Both HTML and structured JSON are requested. Every request sends `Cache-Control: no-store`; snippet responses explicitly confirm `X-Redline-Cache: bypassed`, and native document requests omit idempotency keys. Comparison-cache reads and writes are disabled for snippet samples, which all have nonzero diff timings. Warm distributions measure fresh comparisons in warm execution environments. Baseline rows omit original-page rendering; rows labeled “with rendered pages” explicitly enable it. Fixtures contain generated public content, not customer documents.

Measured server processing uses the final `metrics.totalMs`. It includes normal admission, source retrieval for uploaded inputs, parsing, comparison/rendering, quota work and requested result storage. Client completion is measured when the complete HTML comparison is received; it excludes input staging. Network transit and browser rendering are excluded from server metrics. First requests in this run are retained as separate warmup evidence and are not claimed to be verified cold starts.

**Expected server processing** is the measured p50 plus a 50 ms buffer, rounded up to whole milliseconds. It is a planning estimate, not a measured percentile, upper bound or SLA. Observed timings remain unmodified. DOCX page labels are nominal corpus dimensions; rendered Word pagination was not verified. PDF page counts come from generated source pages.

## Optional page rendering

These rows request `pageRendering: true`. Semantic completion precedes page preparation; final server completion includes both. PDF previews preserve source bytes. DOCX pagination comes from the selected renderer and can differ from Word. Page preparation includes PDF validation and private storage, not browser rasterization.

## Failed qualification cases

Invalid comparison output has no published latency expectation. These cases must be repaired and rerun before making performance claims for them.

- **JSON 100KiB (inline)**: Changed fixture returned no changes. Engine: `text_fallback`. No timing claim.
- **DOCX logical 1MB (upload)**: Benchmark SSE document_too_large; no latency recorded. Engine: `unavailable`. No timing claim.

## Warm distributions

DEV reserved concurrency: snippet service 5; native document service 3. Bursts above these deployed limits may be rejected; partially admitted batches have no aggregate timing claim.

Negative fixtures rejected: 3. Rejected/rate-limited benchmark attempts: 13. Owned fixture cleanup: verified.

Raw observations and fixture hashes are recorded in the adjacent JSON report. Upload authorization/transfer time and browser rendering are not included in the server processing estimates.
