Summary

• Wide Markdown evidence tables could extend past their assistant bubble. Table-bearing V2 replies now fill the available conversation container, while normal prose and user-message widths remain unchanged.
• Long identifiers, JSON, and URLs wrap without reducing font size. A responsive minimum cell width avoids excessively narrow columns; tables that still cannot fit scroll inside a keyboard-focusable region instead of overflowing the conversation.
• Saved, streaming, finalized, and reloaded replies share the layout. Classic chat and the comfortable/wide preference are unchanged.
• Add functional/browser regressions and fix documentation; bump the application to 0.261.425.

Version bump

• application/single_app/config.py VERSION third segment bumped, or not needed because this is docs-only
• deployers/version.txt bumped, or not needed because deployers/ was not changed

Application: 0.261.424 -> 0.261.425. No deployer changes.

Testing / validation

• npm --prefix .\application\v2_ui run build -- --outDir ..\..\ui_tests\artifacts\orchestration-plan-editor - passed TypeScript compilation and production build; Vite reported its existing large-chunk warning.
• python .\functional_tests\test_v2_chat_table_layout.py - 3 passed.
• python .\functional_tests\test_v2_mobile_layout.py - 5 passed.
• python -m pytest .\ui_tests\test_v2_chat_table_layout.py .\ui_tests\test_v2_mobile_chat_layout.py -q --tb=short - 18 passed (9 table regressions and 9 existing mobile regressions). Covers 320-1920px viewports, both themes/width preferences, resizing, citations, streaming/finalization/reload, and keyboard scrolling to the last column.
• python .\functional_tests\test_docs_site_quality.py - 6/6 checks passed.
• git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check - passed.
• Visually inspected desktop and narrow-window results. The new desktop regression failed on the original code, where the table extended to approximately 4533px while the bubble ended at 1040px.

Known baseline failures: The adjacent orchestration streaming suite has missing pending-input API stubs and an outdated Review the running plan button expectation. python -m pytest .\ui_tests\test_v2_orchestration_streaming_bubble.py -q -k "a_run_shows_only" --tb=short reproduced 1 assertion failure and 1 teardown error with all three production UI files restored to their original source. These unrelated tests were left unchanged. UI detector findings concern an existing activity animation and a false positive matching <img> in an accessibility comment, not this change.

Documentation

• Release notes updated, or not needed
• Feature documentation updated, or not needed
• Fix documentation updated, or not needed

Added docs/explanation/fixes/V2_CHAT_TABLE_OVERFLOW_FIX.md. Release notes remain unchanged: approval was requested, but the user was unavailable. No new capability or control requires feature documentation.

Security checklist

• New Flask routes include @swagger_route(security=get_auth_security())
• Settings sent to non-admin frontends use sanitize_settings_for_user()
• Browser JavaScript is served from local SimpleChat static assets only; no CDN-hosted JS
• No secrets, keys, connection strings, or local-only artifacts are included

No routes or settings-response boundaries changed. Markdown keeps semantic React rendering with raw HTML disabled. Build outputs, screenshots, and other local test artifacts are not committed.
