109-118: Whitelist exported keys when parsing helper output.

The loop currently exports any parsed key. Restrict to expected keys to avoid accidental env pollution if output format changes.

predefined whitelist of expected keys (e.g., PYTHON_ARCH, PYTHON_OS, or whatever

Two important branches are currently untested: /lib/libc.musl-* fallback behavior and unsupported CPU handling. Adding those tests will lock in the failure-safe behavior.

(/lib/libc.musl-*) and unsupported-CPU branches by reusing the existing
_stub_ldd helper to emit controlled outputs: one test should stub ldd to print a
musl libc path like "/lib/libc.musl-1.2.3" and assert the script follows the
fallback path behavior, and the other should stub ldd to emit an unsupported CPU
string (e.g., "unknown" or an arch the script treats as unsupported) and assert
the script exits or logs the unsupported-CPU handling; locate and modify the
_stub_ldd usage in the same file to create these cases and add assertions around
the functions that parse ldd output and select CPU/stdlib paths so the fallback

Unconditional fallback PATH prepend still overrides mise binaries.

This was flagged previously as Major and the code remains unchanged — Line 15 unconditionally prepends $HOME/.local/bin:/usr/local/bin, which shadows the mise-provisioned node/bin just placed at the front of PATH on Lines 10–11 and can re-select legacy yarn v1.

25-26: Chained && short-circuits and drops later lint output.

On Line 25 the three linters are chained with &&, so if lint:biome fails, lint:prettier and lint:md-table never run and their findings are hidden until the next stop-gate invocation. Since you're already aggregating into a single output/status, consider running each step independently and OR'ing their statuses so the developer sees all lint problems in one pass.

111-120: Parsing is brittle but fits current helper contract.

The two-pass quote stripping ('^[^=]+="|"$' then '"' → '') works because mise-python-arch only emits simple alphanumeric/hyphen values. If the helper ever emits a value containing " or whitespace, this parser will silently mangle it (inner quotes gone, spaces become list elements via set -gx $_key $_val).

Since the contract is internal and covered by tests, this is acceptable. Consider a tighter parser if the helper's output grows.
