…le guide Document contributor guidelines that are currently only discoverable through issue discussions and PR feedback: - Build instructions (lake exe cache get && lake build) - Sorry policy with the critical caveat that exercise assignments are not always visible in Lean docstrings — a theorem may be assigned as an exercise elsewhere in the textbook (e.g., Theorem 6.1.19 is Exercise 6.1.8, but the Lean source only says "Theorem 6.1.19(a)") - Link to teorth#208 where the sorry policy was discussed - Style conventions (faithfulness over golfing, with teorth#476 as precedent for reverts of proof cleanups) - AI-assisted contribution requirements The sorry policy caveat comes from direct experience: PR teorth#477 was closed because Theorem 6.1.19 appeared non-exercise in the Lean source but is assigned as Exercise 6.1.8 in the textbook.
