• truecalc-mcp: 8.2.0 -> 8.2.1

Changelog

truecalc-core

8.2.1 - 2026-08-28

Other

• (core) read INDEX out of an inline array in place, not out of a copy

truecalc-workbook

8.2.1 - 2026-08-28

Fixed

• (workbook) hide the wasm32-only cap predicates from the public API
• (workbook) move const-vs-const model checks into const blocks
• (workbook) enforce the cell and serialized-byte caps on wasm32 only
• (workbook) seed volatile cells onto the recalc frontier before draining it

Other

• (bench) record the incremental_recalc/block_subtotals_edit_root/10000 baseline
• Merge remote-tracking branch 'origin/main' into chore/899-923-perf-gate
• Merge pull request Enforce the workbook cell and serialized-byte caps on wasm32 only #932 from truecalc/feat/limits-wasm-only
• (workbook) qualify the remaining unconditional 100 MiB cap claims
• (workbook) cover the wasm32 cap gating in the Node example, not just a dead test
• (workbook) fix import ordering in the new limits gating test
• (workbook) cover the wasm32-only gating of the two size caps
• (workbook) guard range dependency edges at recalc level
• Merge pull request perf(workbook): index formula cells by row so a range reference stops costing the whole workbook #917 from truecalc/feat/908-depgraph-index
• Merge pull request perf(workbook): stop scanning the sheet on an empty-cell read, and stop allocating per element #915 from truecalc/feat/904-cell-value-perf
• (workbook) resolve a cell without allocating a key or re-folding sheets
• (workbook) index the stored grid's spill anchors instead of scanning

truecalc-mcp

8.2.0 - 2026-08-27

Added

• (mcp) declare an output schema for the six evaluator tools
• (mcp) echo what was accepted, and flag errors from the outcome
• (mcp) filter list_functions by category, name and count
• (mcp) accept array variable bindings

Fixed

• (mcp) recurse the message normalisation into nested array values
• (mcp) omit structuredContent on the error arm of tools/call
• (mcp) reject undecodable variable bindings instead of dropping them
• (mcp) propagate default-sheet failure instead of panicking
• (mcp) seed a default Sheet1 on workbook_create

Other

• (mcp) assert declared schemas stay open at every nested object
• (mcp) validate a declared tool's structuredContent on the error arm
• (mcp) rustfmt the new test files
