Summary
The released Ota v1.6.27 pressure matrix reproduced a macOS ARM64 linker failure while compiling the Rustler NIF. This is an evidence report only; it does not propose a fix because the isolated ownership boundary has not yet been established.
Environment
- GitHub Actions
macos-latest ARM64 runner
- Elixir 1.16
- OTP 26
- Rust stable
- Ota v1.6.27 from the contract-owned released bootstrap
Reproduction
The failure occurs in the setup closure used by both:
ota run verify:elixir-formatota run verify:elixir-test
The Rust build reaches the linker, then reports undefined Erlang NIF symbols for architecture arm64, beginning with:
Undefined symbols for architecture arm64:
"_enif_alloc_env", referenced from:
librustler-...rlib
Hosted evidence:
https://github.com/bobaikato/pythiaLabs/actions/runs/33517820099/job/99958972200
Retained artifact:
ota-pre-release-native-pressure-macos-33517820099
Adjacent matrix results
On the same macOS run, these surfaces passed:
- MCP smoke
- Rust worker build and tests
- site build
- Action Envelope, VCE, ACI, and local CAEP conformance
The existing site-format/Prettier deviations are separate and intentionally unchanged.
Boundary
This report proves a reproducible macOS ARM64 NIF-link failure in the selected Elixir closure. It does not establish whether ownership belongs to Rustler configuration, linker flags, OTP packaging, or repository build setup, and it does not claim an Ota defect.
