linexcel 1.16.0

[1.16.0] — 2026-10-23

Added

• Add an Excel presentation to the Data tab alongside Datasette filters and
  exports: extract direct styles, theme/indexed colors, row/column dimensions,
  hidden cells and merged ranges from the source OOXML. Browse bounded areas
  with common number/date formatting and keyboard-accessible source details.
• Open the local application with serve --open; use --port 0 to select a
  free port and report its actual mounted URL.
• Configure llama.cpp template thinking explicitly in serve and manual
  acceptance, separately from gateway thinking settings, and include it in
  documentation cache identity.
• Propose seven source-grounded agent workflows for workbook audits, KPI
  explanations, version comparisons, SQL migration, reconciliation, handover
  documentation and calculation discrepancies.

Fixed

• Match acceptance completions through exact prompt/content fingerprints and
  unique local receipt indices, retaining raw provider IDs when a runtime
  recycles them. Reject ambiguous or reused vision receipts.
• Bound glibc allocation arenas in Linux worker subprocesses to reduce
  virtual-address pressure on hosts with many CPU cores, including repeated
  imports for external and quarantined workbooks. Honor explicit settings.
• Validate serve ports before creating storage and provide a recovery hint for
  an occupied port. A failed browser launch leaves the copyable URL available.
• Use exclusive Windows server sockets so an occupied local port receives the
  same recovery hint without reclassifying genuine permission errors.
• Discard malformed AI table rows without losing the surrounding documentation
  or other valid tables.
• Recognize structured AI fences only as complete Markdown blocks, preserving
  prose and formula proofs after inline mentions of table or claim blocks.
• Reframe exported graphs after changing sheets, including equal-sized subsets
  and mobile layouts whose canvas resizes when the node reader closes. Keep
  labels readable in small filtered views of a larger workbook, and discard
  delayed frames after history or camera changes so Back restores its viewport.
• Lay out the current visible nodes after applying graph filters, preventing
  overlapping cards when changing sheets, node types or calculation differences.
• Describe input and named-reference values read through the engine as readings
  rather than recalculations in the exported viewer.
• Scope calculation guidance to Nodes and Graph, support arrow/Home/End
  navigation between the main tabs, and provide a skip link to the workbook.
• Keep formatted presentation separate from raw Datasette values and exports;
  distinguish missing caches, unsupported formats and canonical formula
  fallbacks. Bound XML, format codes and response size, reject entity
  declarations, and discard stale replies after project or sheet changes.

Documentation

• Explain the presentation limits: approximate browser geometry, complex number
  formats, conditional formatting, number-format colors, charts, frozen panes
  and print layout do not establish an exact Excel rendering.
