Extended toolkit-qa-check.sh with 6 new logic validation checks to detect
semantic/behavioral errors that syntactic checks alone cannot catch:
- CHECK 89 (CRITICAL): Inverted/contradictory grep patterns
Detects: grep -v X | grep X (always returns empty, logic error)
- CHECK 90 (HIGH): Type mismatch in comparisons
Detects: Numeric operators on string variables ([ $var -lt 80 ] where var='75.23%')
- CHECK 91 (HIGH): Command argument ordering errors
Detects: Filename before options in grep/sed (grep FILE -e PATTERN)
- CHECK 92 (HIGH): Missing command availability checks
Detects: Uses of optional commands (nc, dig, host, jq) without 'command -v' checks
- CHECK 93 (HIGH): Uninitialized variables in AWK
Detects: AWK variables set in patterns without BEGIN initialization
- CHECK 94 (HIGH): Undefined variable references
Detects: Variables that appear undefined or typos in variable names
Also added helper functions for logic analysis:
- detect_grep_contradiction() - detects contradictory patterns
- infer_numeric_context() - determines if variable should be numeric
- check_awk_var_init() - checks AWK variable initialization
- get_function_vars() - extracts defined variables from functions
These checks complement the existing 88 checks by focusing on logic errors
that would pass syntax validation but cause runtime bugs.
Progress counter updated from /88 to /94 (6 new checks added).
Added qa-suppress annotations to prevent false positives in the QA script itself.
