However, a symbol containing grep regex metacharacters (e.g. parentheses, brackets) could cause grep to error or produce incorrect results.",
      "recommendation": "Sanitize or escape the symbol value before embedding it in the grep pattern. Use grep -F (fixed-string) when word-boundary matching is not strictly required, or pre-validate that symbols match ^[A-Za-z_][A-Za-z0-9_]*$ before use.",

Four LOW/INFORMATIONAL observations recorded: (1) grep regex injection via unsanitized symbol names (no shell execution risk), (2) missing CLI integer lower-bound validation, (3) no project-root confinement check on git-sourced paths, (4) scan output may surface inline secrets from the target codebase. Recommend addressing LOKI-001 and LOKI-002 before production hardening. Overall verdict: PASS."
