        "This curriculum teaches proof-aware cryptographic tooling from first principles to a research-grade professional workflow. It is designed for undergraduate students who know some programming and discrete math, but have not yet worked with formal verification, Lean, certificate transparency, or autonomous-agent risk gates.\n",
        "\n",
        "The practical anchor is PACTA: Proof-Aware Crypto Tooling Agent. The goal is not to build a trading bot. The goal is to teach an agent, and the engineer supervising it, to ask:\n",

        "> Does this theorem cover the exact code path that will protect funds?\n",

        "- Reproduce a local Lean replay or diagnose why local replay is unavailable.\n",
        "- Perform a proof hygiene scan and explain why `sorry`, local axioms, and trivial theorem targets are dangerous.\n",
        "- Explain how a third-party proof-checking provider changes the trusted base.\n",
        "- Implement and verify RFC 9162-style Merkle inclusion and consistency proofs.\n",
        "- Explain why Signed Tree Heads need accountable signatures, why Ed25519 is useful here, and why ML-DSA requires a real backend.\n",
        "- Design policy gates that convert verification evidence into consequences.\n",
        "- Read R4 four-tier apex evidence, name its residual blockers, and write a research plan toward R5 production assurance.\n"

The napkin run teaches the moves; the real-size run proves the moves are the whole story. If a step ever feels like a leap, back up one cell: the smaller rung is there.\n"
