Issues

• RecalcContext::now_serial() truncates to whole seconds, discarding timestamp_ms's sub-second precision

• recalc: cache seed_spill_sensitive's full derived seed set (Design B, deferred from #991)

• Feature request: seed incremental recalc from resolution-status changes (not just an explicit edit list)

• NamedRange/Table ref is not re-addressed on a row/column structural edit

• translate_formula can emit a formula that does not re-parse: =Sheet1!#REF!

• A sheet rename can silently move a formula onto a different live sheet (case-folding mismatch)

• Publish the engine's performance shape, including one sheet vs N sheets, and point the README at it

• recalc_incremental is slower than recalc above ~50 sheets

• A table header filled by a spill is visible to the evaluator and invisible to the dependency graph

• Recover narrow range seeding for a spill footprint a previous recalc retired

• Guard self-referential spills, and adopt the incremental-vs-full differential generator

• chore(ci): --record can only rewrite every baseline at once, downgrading best-of-N entries to single-run

• perf: VLOOKUP, HLOOKUP, LOOKUP and QUERY copy the whole array per call — the same defect #894 fixed in INDEX

• truecalc-mcp bounds imports but not writes — workbook_set can grow a session to an uncatchable abort

• The wasm binding flattens every WorkbookError variant into an untyped Error

• refactor: make the scratch cell key a compile-time guarantee rather than a RefCell invariant

• test: the stored-grid spill fallback is protected by a single assertion

  truecalc/core#919 · Filter by author hhimanshu opened on Aug 28, 2026
  

• perf: trace_cell now builds the whole spill index on every call, losing its laziness

• perf: cycleCells is withheld from the wasm dependency-graph surface pending #908

• Out-of-memory in the wasm build aborts the shared instance and destroys every open workbook

• A blocked spill discards which cell blocked it, returning a bare #REF!

• LET cannot bind and call a LAMBDA — LET(f, LAMBDA(x,x*2), f(3)) returns #NAME?
