v0.0.458

Version 0.0.458 (July 14, 2026)

• Fix agents re-reading files in a loop — read_file results (whole-file text/JSON/CSV head, windowed reads, and PDF page reads) now deliver a bounded content excerpt to the model instead of a bare summary line, with an honest trailer naming the session file and how to page the rest; superseded reads compact to a length marker so long file sessions don't bloat context. Verified live: the agent pages forward with offset/length instead of re-issuing identical reads.
• PDF page-range reads — read_file gains page_range (e.g. '2' or '10-15') for PDFs on Files & Directories and S3 connections: extracts only the requested pages and reports pages_total, so large documents are pageable like large text files instead of all-or-nothing.
• Fix permanent 500 on reports after reading certain PDFs — PDFs with broken ToUnicode CMaps make pypdf emit lone UTF-16 surrogates, which persisted with the completion and crashed every later load of the report (UnicodeEncodeError: surrogates not allowed). Extracted document text is now sanitized at the source, tool payloads are sanitized before persistence, and previously poisoned rows are scrubbed at read time so affected reports load again.
• SharePoint/OneDrive search results show clean paths — file paths in search_files results are now root-relative (Contracts/acme.pdf) instead of the raw Graph parentReference (/drives/b!…/root:/…), matching listings; file rows in the report view also show the path inline, and read_file headers show the file name instead of a truncated opaque id.
