Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

  • gin.Context.Get

Contract

  1. Context.Set stores middleware state that Context.Get returns with its existence flag in later handlers.
  2. ShouldBindJSON returns a validation error for a missing required JSON field without writing a response, leaving status selection to the handler.
  3. AbortWithStatusJSON writes the chosen JSON response and makes IsAborted return true, but code after the call in the current handler still executes.
  4. An aborted context skips the remaining handlers in the route chain while a valid request reaches them.
