# DEV page-flow server validation

Document service: `RELEASE-20261005-2b226981a`. Generated public 10 nominal-page DOCX and 10-page PDF fixtures, direct input, anonymous guest admission. Five measured requests per case after one excluded warmup. Comparisons bypass caches with `Cache-Control: no-store` and no idempotency key. Guest requests are paced; these results are separate from the earlier Creator Pro benchmark.

The browser-only scheduling and shimmer changes do not alter this server flow. Times below are measured medians, not the public planning estimates. Page preparation includes source validation and private storage; browser drawing is excluded.

| Fixture | pageRendering | Comparison | Page preparation | Final server | Diff engine |
| --- | --- | ---: | ---: | ---: | ---: |
| docx-10 | false | 17.0 ms | 0.0 ms | 17.2 ms | 6.1 ms |
| docx-10 | true | 88.1 ms | 199.7 ms | 286.5 ms | 6.0 ms |
| pdf-10 | false | 39.3 ms | 0.0 ms | 39.4 ms | 8.5 ms |
| pdf-10 | true | 109.6 ms | 63.2 ms | 181.4 ms | 8.5 ms |

All cases used the native document engine and passed stage-timing assertions. DOCX preparation used the repaired Unicode renderer. Full observations: [raw evidence](redline-page-flow-server-20261005.json).
