The FeeGuard newsletter

What you get, on a four-week rotation:

• Mechanism — one concept explained completely, in miniature.
• Failure pattern — how this goes wrong in the wild, disclosed as synthetic where it is.
• Do this today — one 10-minute check you can run right now.
• The wider view — ecosystem, tooling, and honest tradeoffs.

Only one issue in four mentions FeeGuard at all — the other three are meant to earn the open on their own.
