curl --proto '=https' --tlsv1.2 -fsSL https://github.com/burkan2/hSUM/releases/download/v0.1.0-alpha.4/install-hsum.sh | bash -s -- --activate . --confirm --allow-unnotarized-alpha

ONE COMMAND. RUN IT FROM THE REPOSITORY YOU WANT TO ACTIVATE. It installs at user level, registers Codex, and activates this repository. On macOS, the command explicitly acknowledges that this alpha is not Apple-notarized; the downloaded binary is still SHA-256 verified. Verify the installer before execution.

Install and smoke-test hSUM 0.1.0-alpha.4 (https://github.com/burkan2/hSUM) for the current Git repository. User-level installation, user-level hSUM state, and the single Codex MCP registration are in scope; do not modify repository files. Confirm this is macOS arm64 or Linux x86_64. Download `install-hsum.sh` and `SHA256SUMS` from the exact `v0.1.0-alpha.4` GitHub release, verify the installer's SHA-256 entry before running it, and review the script. Run it with `--activate . --confirm`; on macOS, explain that this alpha is not Apple-notarized and add `--allow-unnotarized-alpha` only after I explicitly approve that required acknowledgement. Verify that installation reports four read-only tools and a successful citation round trip, and that `hsum integration status codex --json` reports both the registration and agent policy as `current`. Do not ask me to copy TOML, edit Codex configuration, or restart Codex. Report each command and result, including any failure. Documentation is at https://hsum.burkankale.com/docs/0.1.0-alpha.4/ and https://hsum.burkankale.com/llms.txt.

PASTE INTO A CODING AGENT OPENED IN YOUR REPOSITORY. The prompt requires review, explicit macOS approval, and a verified citation round trip.
