+## Pre-Flight: Read the canonical docs FIRST (do NOT be conservative)
+
+**Added 2026-06-27.** This project has extensive canonical documentation. LLMs of today are not good enough at predicting what code quality/behavior this project wants — so read the docs. Being conservative about reading knowledge from markdown files is an ANTI-PATTERN in this codebase.
+
+Before writing the spec, read:
+
+1. `AGENTS.md` — the project-root agent-facing rules; especially the HARD BANs (git restore/checkout/reset, opaque types in non-boundary code)
+2. `conductor/workflow.md` — including §0 (Python Type Promotion Mandate) and the Tier 1 Track Initialization Rules
+3. `conductor/tech-stack.md` — including the Core Value reference at the top
+4. `conductor/product.md` — product vision + primary use cases
+5. `conductor/product-guidelines.md` — **Core Value section is mandatory reading**: C11/Odin/Jai semantics in a Python runtime
+6. `conductor/code_styleguides/data_oriented_design.md` §8.5 — the Python Type Promotion Mandate
+7. `conductor/code_styleguides/python.md` §17 — the LLM Default Anti-Patterns (banned patterns)
+8. `conductor/code_styleguides/type_aliases.md` — Metadata is the boundary type
+9. `conductor/code_styleguides/error_handling.md` — Result[T] + NIL_T sentinels
+10. The relevant `docs/guide_*.md` for the layers the track touches
+11. `conductor/tracks.md` — check existing tracks for similar work (don't re-invent)
+

-2. **Generate Track ID:**
+2. **Apply the Python Type Promotion Mandate (workflow.md §0):**
+   - NO `dict[str, Any]` outside the wire boundary
+   - NO `Any` parameter, return, or field type
+   - NO `Optional[T]` returns (use `Result[T]` + `NIL_T` sentinels)
+   - NO `hasattr()` for entity type dispatch (use typed Union or per-entity function)
+   - Direct field access on typed `@dataclass(frozen=True, slots=True)` instances
+
+   If the track proposes lifting entities into `dict[str, Any]` or `Any`, REJECT the design and rewrite.
