+# ban_local_imports — v1
+
+**Why this iteration:** Lifted verbatim from `.opencode/commands/mma-tier3-worker.md:42-46` (the current canonical source). The plan referenced `conductor/code_styleguides/python.md` §17.9a (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:42-46` (originally `conductor/code_styleguides/python.md` §17.9a, drift-corrected)

+- Local imports inside functions (top-of-module imports only)
+
+**The one exception:** the literal wire boundary (TOML/JSON parse functions) may use `dict[str, Any]` + `Metadata.from_dict(...)`.
