Flight Core Unsafe Review

Flight Core treats unsafe or privileged operations as reviewed exceptions, not

normal source forms. The source of truth is space/flight-core-unsafe-ops.tsv.

Review-Required Operations

The S1 profile requires review rows for:

• MMIO and volatile register access;
• FFI or ABI boundary calls;
• CPU-specific operations;
• manual memory operations.

Each row must include a review ID, source path, target assumption, failure

mode, evidence path, and reviewer. A source file that uses one of these terms

without a known flight-core-review: marker fails with

FLIGHT_CORE_UNREVIEWED_UNSAFE.

Target Boundary

The local repository accepts emulation evidence for S1. Physical board claims

remain blocked until the physical evidence gate receives complete target

artifacts.
