# ban_prefix_aliasing

## v1

**Why this iteration:** Lifted verbatim from `.opencode/commands/mma-tier3-worker.md:43` (the current canonical source). The plan referenced `conductor/code_styleguides/python.md` §17.9b (lines 364-443) but that section no longer exists in python.md after a 2026-06-27 refactor — the §17.9 content was moved into the agent role prompts (this file). This v1 is the baseline encoding — the imperative-ban style currently in production.
Future variants will test alternative encodings (rationale-first, before/after, tabular) against this baseline.
**Source:** `.opencode/commands/mma-tier3-worker.md:43` (originally `conductor/code_styleguides/python.md` §17.9b, drift-corrected)
