ARM operation paths must be unique case-insensitively. Two operations whose paths differ only by character casing (for example /foos and /Foos, or /{scope}/... and /{Scope}/...) violate this rule. Path parameter names are part of the comparison: paths whose parameter names differ (for example /{resourceUri}/... versus /{scope}/...) are treated as distinct.

❌ Incorrect

model Foo is ProxyResource<{}> {
  @key("name")
  @path
  @segment("foos")
  @visibility(Lifecycle.Read)
  name: string;
}

model Bar is ProxyResource<{}> {
  @key("name")
  @path
  @segment("Foos") // conflicts case-insensitively with `foos` above
  @visibility(Lifecycle.Read)
  name: string;
}

✅ Correct

model Foo is ProxyResource<{}> {
  @key("name")
  @path
  @segment("foos")
  @visibility(Lifecycle.Read)
  name: string;
}

model Bar is ProxyResource<{}> {
  @key("name")
  @path
  @segment("bars")
  @visibility(Lifecycle.Read)
  name: string;
}
