You are an adversarial verifier for a FreeCAD-wasm code review. A reviewer claims: SEVERITY: medium CATEGORY: internal-contradiction FILE: /home/magik6k/lcad-wasm/freecad-port/research/R10-eh-jspi-asyncify-findings.md SUMMARY: STATUS and R10 contradict each other on the ASYNCIFY_STACK_SIZE fix for the boolean-cut hang. DETAIL/EVIDENCE: STATUS.md:26-28 states 'Bumping ASYNCIFY_STACK_SIZE to 64 MB did not help -> not stack overflow.' R10 line 49-51 (same session) lists 'bump -sASYNCIFY_STACK_SIZE to ~16MB' as an untried fix 'to try'. These cannot both be current: STATUS says a larger 64MB bump was already tried with no effect, while R10 proposes trying a smaller 16MB bump. R10 is stale on this point. RECOMMENDATION: Reconcile the two docs; if 64MB was tried and failed, remove the stack-size suggestion from R10's 'fixes to try' and update its hypothesis (b). Independently verify by reading the actual file(s) and running git/grep as needed (repo at /home/magik6k/lcad-wasm/freecad-port/FreeCAD, toolchain at /opt/toolchains, deploy at /home/magik6k/lcad-wasm/freecad-port/deploy-gui). Default to REFUTED if you cannot confirm the evidence. Adjust severity to what the evidence actually supports.

thinking
I'm looking at what appears to be a contradiction between two documents. STATUS.md claims that bumping the stack size to 64 MB didn't resolve the issue, ruling out a stack overflow problem. But R10 is still suggesting similar fixes like increasing the stack size to around 16 MB, which seems inconsistent with the earlier conclusion that this approach didn't work. The contradiction is genuine and confirmed. It's purely a documentation inconsistency where R10's proposed fix has already been tested and ruled out by STATUS, so it could misdirect effort. I'm settling on low severity since it's a docs-only issue with limited practical impact—easily reconciled once noticed—though medium could be jus  …

Both files confirm the reviewer's evidence. STATUS.md lines 26-28: - "Bumping `ASYNCIFY_STACK_SIZE` to 64 MB did not help → not stack overflow." R10 lines 49-51: - Hypothesis (b): "`ASYNCIFY_STACK_SIZE=131072` overflows on OCCT's deep recursion..." - "Fixes to try: bump `-sASYNCIFY_STACK_SIZE` to ~16MB..." STATUS is dated 2026-07-04 session 2, and its "⭐ Session 2" header explicitly points to research/R10 as the same-session artifact, so both are meant to be current. STATUS reports that a 64 MB stack bump was already tried and ruled out stack overflow as the cause, while R10 still lists a smaller ~16 MB stack bump as an untried fix and retains stack overflow as live hypothesis (b). These cannot both be current — R10 is stale on this point. The contradiction is genuine and precisely as described. One nuance: STATUS frames the hang as occurring specifically when driven from a startup script (progress-sequencer suspends before the event loop yields), whereas R10 frames it more generally. But that framing difference does not rescue the stack-size contradiction — STATUS's "did not help → not stack overflow" directly negates R10's proposed stack-size fix and hypothesis (b). Severity: this is a documentation-only inconsistency in research/status notes (no code impact). It could misdirect future effort toward an already-ruled-out fix, but it is non-blocking and self-contained. I adjust from medium to low.
