- Do not use `git restore` while a user is mid-conversation without first confirming the desired state
- HARD BAN: `git restore`, `git checkout -- <file>`, `git reset` are FORBIDDEN without explicit user permission in the same message. They destroyed user in-progress src/* edits twice in one session (2026-06-07). If you think you need one, ASK FIRST.
- **HARD BAN: Day estimates in track artifacts (Tier 1).** Do NOT include day / hour / minute estimates in spec.md, plan.md, metadata.json, or any other track artifact. Day estimates are inaccurate noise; Tier 2 capacity is bounded by attention, not time. Measure effort by **scope** (N files, M sites, N tasks). The user / Tier 2 agent decides the actual pacing. See `conductor/workflow.md` §"Tier 1 Track Initialization Rules" for the full rule, replacement patterns, and rationale. (Added 2026-06-16 per user feedback: "Day estimates are inaccurate. Tier-2s can only do so much in a single track and there is no way in hell its going to be 'DAYS'.")
- **HARD BAN: Opaque types in non-boundary code (added 2026-06-25).** LLMs default to `dict[str, Any]`, `Any`, `Optional[T]`, `hasattr()` polymorphism, and `.get('field', default)` because that's idiomatic Python training data. **All of these are BANNED in non-boundary code.** Use typed `@dataclass(frozen=True, slots=True)` with explicit fields; use `Result[T]` + `NIL_T` sentinels instead of `Optional[T]`; use direct attribute access instead of `.get()`. The ONLY place `dict[str, Any]` is allowed is the literal wire boundary (TOML/JSON parse functions); 2-3 functions per file. See `conductor/product-guidelines.md` "Core Value", `conductor/code_styleguides/data_oriented_design.md` §8.5 (The Python Type Promotion Mandate), `conductor/code_styleguides/python.md` §17 (LLM Default Anti-Patterns), and `conductor/code_styleguides/type_aliases.md` for the canonical mandates. User direction 2026-06-25: "I want the closest thing to c11/odin/jai in a scripting language... metadata should not be a dict[str, any]."
