Summarize the methodology and key conclusions of 3 recent remote-work studies in a table, with sources.

CSTOKEN Large

Here are the key differences in a table.

Study	Methodology	Key conclusion
Bloom (2015)	Randomized controlled (RCT)	Productivity +13%, less attrition
OECD (2022)	Cross-country panel	Effects vary widely by country
Barrero (2023)	Large-scale survey	Hybrid best for satisfaction

Sources ① Bloom 2015 ② OECD 2022 ③ Barrero 2023

This token verification function lets expired tokens through. Find the cause and fix it.

CSTOKEN Extra Large

The expiry check is missing. Fix it like this.

function verify(token, now) {
  if (!token.sig) return false;
  if (token.exp <= now) return false; // block expired tokens
  return check(token.sig);
}

I also suggested 2 boundary-case tests.

Rewrite this meeting note as an executive summary.

CSTOKEN Large

Q3 retention improved 4.2%p versus the prior quarter. The onboarding revamp was the main driver, and churn concentrates at the payment step. For Q4, I recommend prioritizing a simpler payment flow.
