• Chat History Citation Amplification

  • Citation Amplification helps the chat carry forward useful information from documents that were already referenced earlier in the conversation, so you can ask follow-up questions more naturally. Instead of making you start over or reselect the same files, it brings forward the most relevant context from those earlier sources. This makes answers feel more continuous, consistent, and grounded in what was already discussed.
  • Fixed follow-up prompts so prior assistant turns can reuse stored citation results, including tabular tool outputs, instead of relying only on the visible assistant message text.
  • Assistant history replay now hydrates stored citation artifacts and deduplicates repeated cross-sheet tabular calls so later file results, such as Licensing workbook values, remain available to the next turn.
  • History-context diagnostics remain available in message metadata and optional debug citations, while the thoughts timeline stays compact.
  • (Ref: route_backend_chats.py, functions_message_artifacts.py, chat-thoughts.js, chat-messages.js, test_chat_stream_history_context_fix.py, CHAT_STREAM_HISTORY_CONTEXT_FIX.md)

• Document Revision Visibility and Storage Preservation

  • Fixed same-name document uploads so new revisions now inherit the previous document's editable metadata, including classification, tags, title, abstract, keywords, publication date, authors, and sharing state.
  • Workspace lists and chat search now only use the current revision, while older revisions remain retained for future comparison work instead of staying active in normal workspace flows.
  • Document deletion now offers a choice between deleting only the current revision or deleting all stored revisions for that document family.
  • Blob storage now preserves older source files by keeping the active document at the existing alias path and archiving prior current revisions into a revision-family hierarchy before the alias path is overwritten.
  • (Ref: document revision families, current-only workspace visibility, hybrid blob alias plus archived revision storage, functions_documents.py, functions_search.py, route_enhanced_citations.py, workspace/group/public document flows)

Pull request overview

This PR focuses on tightening versioned fix documentation + test coverage while delivering a set of chat history / citations improvements and document revisioning behavior (current-only visibility, revision-family deletion choices, and blob archival behavior).

Changes:

• Adds/updates Playwright UI tests and functional regression scripts covering revision-aware delete modals, chat tag resets, agent-citation hydration, and tabular analysis flows.
• Updates frontend + backend to support revision-choice delete modals, enhanced-citation historical metadata fetch, and richer chat history context diagnostics/citation replay.
• Updates fix documentation + release notes and bumps application/single_app/config.py to 0.240.055.

• The release notes add a top section for v0.240.053, but application/single_app/config.py is bumped to 0.240.055 in this PR. The latest release-notes heading should match the current config version (or there should be newer sections for 0.240.054/0.240.055 above 0.240.053) so the changelog aligns with what the app reports.
