Opus 5.5 reasoning prompt to extract loop invariants, pre/post conditions, and safe refactor steps before touching production payment or credit code.
Analyze the supplied module for a safe refactor. Steps (show work): 1. List public entrypoints and side effects (DB, HTTP, filesystem). 2. For each non-trivial loop/recursion: state invariant, variant function, and termination argument. 3. Identify hidden coupling (shared mutable state, implicit ordering). 4. Propose refactor as small steps; each step must preserve observational equivalence for listed entrypoints. 5. Flag race conditions under concurrent calls. 6. Output test cases that would fail if invariants break (table: input, expected, property checked). Do NOT rewrite code until step 6 is approved. Use markdown headings.
Paste one service file at a time from src/modules/. Cross-check with existing tests; Opus adaptive thinking helps on FIFO credit logic.
