Verify OpenSRE on macOS Apple Silicon (arm64) via curl installer

**Claiming this issue**: ask in OpenSRE Discord (https://discord.com/invite/opensre) before you start so a maintainer can assign it. This is a **dogfood / verification** card — not a code refactor. Pass = comment results on the tracking epic. Fail = open a focused bug and link it here. ## Environment - **OS:** macOS 14+ (Apple Silicon) - **Arch:** arm64 - **Install:** curl one-liner (user install, no sudo) ```bash curl -fsSL https://install.opensre.com | bash ``` Docs: https://github.com/Tracer-Cloud/opensre/blob/main/docs/quickstart.mdx (macOS / Linux tab) ## Pass checklist ```text Environment: OS: macOS … Arch: arm64 Install: curl install.opensre.com OpenSRE: … Python: … Pass checklist: [ ] 1. Install completes; `opensre --version` prints a version [ ] 2. `opensre doctor` (or equivalent) does not hard-fail on PATH [ ] 3. `opensre onboard --help` / wizard starts or documents next step [ ] 4. Interactive shell opens on a TTY (`opensre`) OR documented non-TTY landing page [ ] 5. One slash command works: `/help` or `/status` [ ] 6. Offline fixture gate: `opensre investigate -i ` reaches credential gate or runs (no crash) [ ] 7. (Optional) `opensre gateway status` after `gateway start` Attach: truncated terminal log (redact secrets) + macOS version / `uname -a`. ``` ## On failure Bug title: `[macos/arm64/curl] ` — include checklist step + command + truncated stderr. ## Out of scope Homebrew path (separate card), full test suite, CloudOpsBench.
