linexcel 1.15.0

[1.15.0] — 2026-10-16

Added

• Browse imported worksheet data in serve with an embedded, read-only Datasette
  instance: Excel column letters, saved values, filtering, sorting and cell-level
  formula/source provenance, protected by the workspace's existing ownership.

• Preserve original OOXML formula text, canonical engine formulas and
  decomposition separately, with file/part/cell fingerprints and shared-formula
  translation status. Expose these sources in exported and live viewers.

• Add versioned factual-review instructions across all prompt languages and
  typed claim-to-evidence checks; distinguish these checks from semantic review.

• Generate documentation through an initial draft and a bounded specialized
  review against the same exact source dossier. Retain both prompts, responses,
  checks and cumulative usage; a failed review cannot become a reviewed draft.

• Journal received validation completions and their usage immediately, including
  rejected responses, so an interrupted language does not erase completed calls.

• Supply explicit engine/cache readings, reference intersection and union
  facts, node/group identities, directed topology and omission scopes to the
  factual-review v5 rubric. Check explicitly bound scalar arithmetic claims
  without presenting these checks as certification of arbitrary prose.

• Identify literal 3D references across worksheets without inventing their
  sheet or cell counts; keep opaque decomposition counters separate from
  established range geometry.

• Measure XML/presentation spelling, literal cached strings and separate VBA
  full/graph/excerpt bounds; retain exact sent dossier JSON and its hash
  independently of the parsed evidence fingerprint.

• Require explicit claim ledgers in new dossiers, flag missing, empty
  or multiple ledgers, and distinguish presentation formulas from stored XML
  in validation-report field roles.

• Insert original, stored XML and canonical formula proofs deterministically
  from focal-node fields or an exact retained overview node ID, with separate
  insertion hashes and bounds,
  rather than asking the model to copy long source expressions.

• Read .xlam and legacy .xla VBA through the public read_macros API and
  linexcel macros command. Include static add-in sources in serve; add-in
  reports explicitly omit worksheet calculation and context.

• Add a pinned public Excel corpus downloader and --corpus-manifest acceptance
  replay. Verify source hashes before and after analysis and keep local source,
  image, model and review evidence separate.

• Add a prioritized continuous-improvement plan, open-issue evidence gates,
  a Markdown cleanup inventory and a specialized factual-review methodology.
  Study Excelize as an optional formatted-value oracle before adopting a reader.

• Allow manual acceptance to load an explicitly selected .env and use a
  separate vision endpoint. Authenticate gateway model discovery without
  forwarding gateway credentials to a separate loopback runtime.

• Add explicit --reasoning-split acceptance configuration for compatible
  providers, keeping their reasoning blocks out of displayed documentation.

• Add opt-in streamed text and vision responses with final token usage; require
  a complete stop finish and close interrupted streams. Expose --api-stream
  in manual acceptance without changing the default provider behavior.

• Add explicit --api-thinking manual-validation configuration for providers
  supporting it and retain final response text in completion receipts,
  including rejected length-limited responses.

• Expose response limits, streaming, reasoning split and thinking settings in
  serve; accept the generic gateway API key only for remote endpoints and
  invalidate completed documentation caches when response settings change.

Changed

• Refresh the locked environment with Dependabot's Formualizer 0.11.1,
  python-calamine 0.8.3, OpenAI SDK 3.28.0, Playwright 1.63.0, Ruff 0.17.0
  and ty 0.0.86 updates, retaining the declared minimum versions.
• Cover the engine update with versioned native and integration contracts for
  literal criteria, power associativity, logical error propagation and
  AGGREGATE's error-handling options; retain the lazy metadata guards.
• Update pinned GitHub Actions to setup-uv 10.3.0, upload-artifact 7.0.2 and
  download-artifact 8.0.2 while preserving the expanded browser test coverage.

Fixed

• Use the current generator annotation for progress context managers so the
  updated type checker accepts them without changing progress reporting.

• Keep a stable lazy graph canvas, common-node positions and camera while
  selecting nodes, polling calculations or returning from another tab; restore
  bounded navigation snapshots on Back instead of rebuilding the whole view.

• Calculate each visited formula cell immediately in its own targeted worker,
  including the first graph selection. Old manual-mode preferences no longer
  suppress calculation; source inputs and static VBA remain read-only.

• Keep result-loading and calculation failures local to their node; a delayed
  stored result cannot interrupt a newer selection or prevent recalculation.

• Retry refused or failed calculations without falling back to an older result,
  share active work only before cancellation, and publish terminal task status
  atomically with its metadata.

• Show source formulas once in the graph reader, move canonical/XML proofs into
  an expandable section, and shorten graph controls and help text.

• Keep primary graph navigation compact on mobile and move secondary controls
  into accessible options; make local exploration available from dense views.

• Synchronize the canvas hit-test geometry after readability notices move it,
  preserving native card clicks, camera and positions at desktop/mobile sizes.

• Reset a newly selected source reader to its heading and restore its scroll
  on Back; clear graph hover highlights when the pointer leaves the canvas.

• Distinguish active cell, source input and static VBA guidance instead of
  referring to the removed recalculation-mode switch; scope dense-view and
  empty-graph guidance to static procedures when inspecting add-ins.

• Keep the graph sheet picker complete, in workbook order and mounted during
  refreshes; report selection progress and explain cells without relationships.

• Explore graph neighborhoods from 1 to 20 levels with accessible increment
  controls, mixed-direction paths and truthful node-budget/loading notices.

• Open the Captures tab immediately, show loading and retry errors locally,
  and recover older saved images when recent capture results are empty.

• Keep lazy graph counts and edges within the actual loaded neighborhood;
  prevent range memberships outside that neighborhood from crashing the canvas.

• Preserve native renderer exit codes in capture failures and start with an
  explicit 1024 MiB budget, bounded by server limits. Retain requested lower
  budgets, worker memory isolation and the macro-disabled rendering profile.

• Preserve literal string differences in the viewer's separator-heuristic label;
  the label no longer claims numerical or textual equality.

• Inspect large sheet images through complete, native-size evidence crops with
  image hashes and coordinates; bound observations to the regions actually sent.

• Isolate each native vision crop in its own request so a neighboring image
  cannot supply its quotations.

• Retry invalid vision JSON once with a complete new response; retain both
  attempts, crop identity, receipts and token usage, without trimming output.

• Preserve apostrophes and literal HTML entities in visual quotations in the
  live and exported viewers.

• Keep a searchable, paginated source reader available when the exported
  viewer's graph library fails to load, with explicit bounds on relation lists.

• Resolve misplaced focal formula tokens in workbook overviews to explicit
  missing evidence, without borrowing source text from a sampled node.

• Remove code wrappers around formula placeholders before inserting standalone
  source blocks, preserving readable proof fences and the unchanged raw response.

• Resolve exactly uniform or fully transparent image regions from their actual
  decoded pixels. Record local evidence with zero model requests, reject text
  claims on those regions and retain real vision requests for nonuniform crops.

• Bind overview formula proofs to an explicitly selected retained node rather
  than an unavailable focal field or a neighboring example.

• Bound workbook overview examples with explicit omission counts while keeping
  each retained formula's source evidence intact; preserve static VBA relation
  types and uncertainty in the lazy index and compatibility export.

• Keep sheetless VBA nodes in reproducible acceptance samples; expose explicit
  API retry configuration and sanitized failure-stage evidence.

• Use disposable LibreOffice profiles with no trusted macro locations when
  rendering or recalculating validation workbooks; never execute imported VBA.

• Keep expanded operation and AI settings inside the serve sidebar. Preserve
  all-sheet navigation, open input cells before internal names on data-only
  sheets, handle empty sheets and ignore stale selection replies.
  Fit the workbook graph and allow its reader to be hidden for an overview.

• Remove the unintended self-cycle from the broken-reference stress scenario;
  record formula count, grouping, engine version and value provenance so its
  timing cannot be confused with recovery or large-workbook acceptance.

Documentation

• Archive eleven superseded task mandates and scoped reviews with their original
  bodies, dated scope banners and search exclusion. Keep current policy,
  acceptance requirements and surviving evidence gates in the active guides.
• Document remaining uncertainty in AI prose and vision after specialized
  review; source integrity and successful generation do not certify facts.
