linexcel 1.11.0

[1.11.0] — 2026-09-26

Added

• Show and generate node AI documentation beside the interactive graph, sharing
  the same result with the detail card. Report input, output and total tokens
  separately, including when accounting is estimated or unavailable.

• Add English and French application interfaces, independently of the AI
  documentation language, and reproducible English application screenshots.

• Add explicit AI documentation tasks for individual nodes, workbook overviews
  and selected captures in the web application, with server-owned provider
  settings, operation budgets, persistent results and source provenance.

• Detect copied formula patterns structurally in the lazy application, preserving
  relative/absolute reference semantics and individual cell results. Expose
  group membership and let existing projects refresh their structure.

• Add a reproducible local corpus probe for the lazy application, sampling
  OOXML workbooks across datasets and file sizes and formula targets across
  sheets/signatures. Preserve selection hashes, isolated task outcomes and
  saved-value comparisons under ignored validation storage.

• Add a first deterministic lazy web application (linexcel serve) and a
  mountable WSGI factory with host authentication integration. Import the main
  workbook and references through the interface; build a structural graph
  without recalculation, then evaluate complete supported target dependencies
  in an isolated process. Keep ranges compact and unsupported dependencies
  explicit. Add per-operation budgets/cancellation, persistent task history,
  revision/version-aware caching, forced recalculation, cache comparisons,
  deterministic captures and JSON export. Separate user storage, coordinate
  worker/memory admission and preserve prior results on failure. External
  references currently support simple literal inputs; see README for calculation
  and server deployment limits. AI remains optional and explicitly requested.

• After confirmed isolated-worker memory exhaustion, recover a bounded source
  inventory in up to two fresh workers under the original time/memory budgets.
  Stored-cell quotas are divided across worksheets and reduced fourfold on a
  further memory failure. Recovery never recalculates truncated inputs, builds
  dependency edges or claims completion; missing caches stay unknown and dates
  may remain raw serial numbers. Preserve the initial failure and all attempts.
  Disable with --memory-retries 0 / ExecutionPolicy(memory_retries=0);
  targeted analysis, cancellation, timeout and unknown crashes do not trigger it.

Changed

• Present sheet captures as a thumbnail gallery with a selected-image view,
  replace native file controls with accessible styled upload buttons, and
  highlight bounded JSON previews while omitting image payloads from operation
  details. Keep complete results available through explicit downloads.

• Move the graph center to the selected sheet and keep sheet selection consistent
  during cross-sheet navigation; avoid oversized initial zoom for isolated nodes.

• Restore an interactive directed graph in the lazy application with the
  bundled offline Cytoscape library, pan/zoom, framing, sheet navigation,
  selection details and an accessible list alternative. Keep compact-range
  membership distinct from formula dependencies and bound only the display.

• Expose formula dependency results from the same targeted engine operation,
  separately from saved caches and literal inputs. Report unavailable results
  and calculation coverage explicitly; reading dependency values does not
  trigger additional volatile recalculations or claim a branch execution trace.

• Organize the lazy graph around sources, the selected node and its usages,
  with search, back navigation and explicit compact-range membership. Restore
  dedicated deterministic node cards with formula highlighting, source/cache
  provenance, nearby source labels and readable dependency decomposition.

• Separate main-workbook and reference upload areas, support drag and drop,
  show removable file selections and transfer/import progress, and preserve
  valid selections when an upload needs correction.

• Poll active operations individually instead of repeatedly transferring the
  whole graph and result history; idle workspaces use a lightweight connection
  check. Make empty-string results and volatile calculations explicit.

Fixed

• Reuse the newest matching calculation after server restart, independently of
  filesystem enumeration order. Exclude obsolete implementation results from
  new AI dossiers and preserve value types in both node and workbook evidence.

• Correct typed SUMPRODUCT array handling, error propagation through text
  concatenation and mixed-type comparisons inside the calculation graph, so
  dependent formulas use corrected results rather than patched final values.
  Preserve source formulas and distinguish Excel errors from matching text.

• Resolve constant defined names and sheet-local bindings, preserve stored
  empty strings, and keep literal reads independent of the calculation engine.
  Reject excessive formula depth before native parsing in targeted calculations.

• Preserve exact stored date serials and numeric calculation output, including
  Excel's fictitious 29 February 1900, instead of round-tripping through Python
  calendar dates. Keep source date formatting separate from numerical results.

• Distinguish Boolean values from numeric values and compare date values using
  the workbook's date system when checking a targeted recalculation against the
  saved Excel cache. Preserve readable date values in the detail card.

• Preserve external-link advice and reference-folder read warnings when analysis
  stops before the native engine finishes. Interrupted reports label those
  links as declarations which may be obsolete, without claiming active usage.
  Recommend --refs-dir DIR in report warnings even when external values are
  cached, without repeating the CLI hint.
