Summary

Publish the Shanghai2026-11-14 bilingual tutorial websocket-offline-model-options in the existing article corpus and archive. Explain offline versus streaming model options, the source fix in #3887/#3888, copied-script versus package identity, and a read-only AST audit that does not import the server or load weights.

Keep the existing featured navigation, layout and previously published articles unchanged. The dated article references pinned public source and states the synthetic routing evidence limits; it makes no pretrained quality, performance or adoption claim.

Validation

• Missing catalogue entry reproduced as one expected failing test before article insertion.
  -22 scoped Python tests pass:11 new article tests plus11 existing article tests. Both source and built pages execute the source-inspection example.
• Two deterministic builds:277 files, each with210 validated HTML pages.
• Four new-article private desktop/mobile ZH/EN browser cases pass; screenshots reviewed.
• Full exact-head site/browser/docs CI is required before normal merge. Public deployment and actual-page hashes are separate post-merge gates, not yet claimed by this PR.

This is a static documentation change only. No new ASR/GPU quality experiment, model download or production service operation.
