    # `test/fixtures/` and the calldata-fixture regeneration script under
    # `scripts/` are included so consumers can verify the on-chain
    # ABI/calldata oracle and reproduce it without cloning the GitHub
    # repo. This matches the convention `polymarket_clob` already uses
    # for its parity fixtures.
    #
    # `scripts/node_modules/` is intentionally NOT included — it is a
    # local install of ethers.js used only by the regeneration script,
    # gitignored, and ~23MB. Listing the specific scripts files instead
    # of the directory keeps it out.
    #
    # `AGENTS.md`, `PACKAGE_PLAN.md`, and `SDK_SURFACE_PLAN.md` are
    # intentionally excluded: internal AI/dev-process planning notes
    # that are not authoritative for users of the library.

    # Phase 5 scaffold: the SDK depends on polymarket_clob for low-level CLOB
    # auth, signing, orders, and market reads. Higher-level Polymarket APIs
    # (Gamma, Data, CTF, pUSD, RTDS) live in this package.
    #
    # The path-based dep is the workspace-local form; set HEX_BUILD=1
    # to switch it to the Hex requirement for `mix hex.build` /
    # `mix hex.publish` (publish polymarket_clob first).
    #
    # `:req` is reintroduced in Phase 6 because `Polymarket.Gamma` issues
    # first-party HTTPS calls against `gamma-api.polymarket.com`. `:plug`
    # comes back as a test-only dep so `Req.Test.json/2` and
    # `Plug.Conn.send_resp/3` remain available in the test suite.
    #
    # `:websockex` is reintroduced in Phase 10 because `Polymarket.RTDS`
    # `use WebSockex` for the real-time trade feed.
    #
    # `:jason` is reintroduced in Phase 10 because `Polymarket.RTDS`
    # directly encodes subscription messages and decodes incoming frames.
    # Other modules continue to rely on Req's built-in JSON decode step
    # (Jason reaches them transitively).
    # `:ex_keccak` is reintroduced in Phase 11a because `Polymarket.ABI`
    # computes function selectors as the first 4 bytes of
    # `keccak256("functionName(types)")`. The polymarket_clob package
    # already depends on it, but per the package-direct-dep convention
    # (Phase 4.5 / 6.1 / 10), modules under `lib/polymarket/` that
    # reference a third-party module by name declare the dep directly.
