OpsScript Gate v0.9.2
Runtime Verification Gate for Shell Scripts

ShellCheck passed with zero warnings.
Your installer still crashed on Alpine.

Syntax linters inspect AST tokens and quoting rules, but cannot determine whether external binaries exist on target systems. OpsScript Gate runs your scripts inside isolated, unprivileged container matrices to catch missing commands, dialect traps, and unattended hangs before release.

Live Discrepancy Verification

Contrast clean syntactic passes with isolated container failures in real time.

Validates AST syntax structure and POSIX variable expansion rules.
Blind Spot: Cannot verify whether external packages or binaries exist on target image.
OpsScript Gate Runtime (v0.9.2) 1 DISTRO FAILED
Executes in unprivileged, isolated containers across Linux distributions.
Resolution: Captures container exit codes, exact missing commands, and line annotations.
Remediation Suggestion Exit Code 127

The execution path calls apt-get. Alpine Linux base images use apk, resulting in termination at line 6.

# Portable conditional dispatch across package managers:
if command -v apt-get >/dev/null 2>&1; then apt-get update -qq && apt-get install -y curl;
elif command -v apk >/dev/null 2>&1; then apk add --no-cache curl; fi
