Function compileStrategy

Compile and register a strategy Compiles raw strategy source and registers it, returning its strategyId.

This answers one question: is the source valid Java. It compiles, registers, and hands back the id — nothing more. Whether the class can actually run is POST /strategy/{strategyId}/validate, and everything known about a strategy, validation included, is read from GET /strategy/{strategyId}. One place to ask, so there is no second answer to keep in step.

The strategyId is derived from what the code means, not from how it is written. Adding a comment, inserting a blank line, re-indenting, reordering imports, or moving a method around all return the same id — you have not created a second strategy. Renaming a variable, changing an identifier's case, reordering fields, or reordering statements inside a method return a different one.

Two rules follow, and they are worth designing around:

• re-submitting a strategy you have only reformatted is free, and gives you back the id you already had, along with any validation already recorded against it;
• the id says nothing about behaviour. Two sources that compute the same thing by different means are two strategies, because deciding otherwise would mean deciding program equivalence.
