+exec() has an unfixable flaw: it reads command output LINE-BY-LINE into an array, which:
 - Hits memory/buffer limits on large outputs (>1MB typical)
 - Silently truncates output without throwing errors or exceptions
 - Causes catastrophic failures in compilation, bundling, and error reporting
-- Makes debugging impossible (you see partial output with no indication of truncation)
+- Makes debugging impossible (partial output with no indication of truncation)
 
 Real-world example from this codebase:
-- jqhtml compilation of 220-line template was truncated at row 4 (mid-line)
+- jqhtml compilation truncated at row 4 (mid-line) - output was 4KB instead of 35KB
 - No error thrown, no indication of failure
 - Took hours to diagnose because the truncation was SILENT
-- Fixed by replacing exec() with proc_open() - output jumped from 4KB to 35KB

+                $resolution = "REQUIRED ACTION - Replace exec() with shell_exec():
 
-QUICKEST FIX (Drop-in replacement - no refactoring needed):
+BASIC USAGE (don't need return code):
-Use \exec_safe() - RSpade framework helper with identical signature to exec():
+    \$output = shell_exec(\$command . ' 2>&1');
-
-    \exec_safe(\$command, \$output, \$return_var);
-
-Simply replace exec() with \exec_safe(). That's it. No other code changes needed.
-Uses proc_open() internally to handle unlimited output without truncation.
-
-Example:
-    // Before:
-    exec('git status 2>&1', \$output, \$code);
-
-    // After:
-    \exec_safe('git status 2>&1', \$output, \$code);
-
-Benefits:
-- Zero refactoring - maintains exact same signature as exec()
-- All existing code continues to work identically
-- No silent truncation (uses proc_open() internally)
-- Framework helper function available everywhere
-
-FOR ADVANCED USERS (Need full control):
-Use proc_open() which streams unlimited output without size limits:
-
-    \$descriptors = [
-        0 => ['pipe', 'r'],  // stdin
-        1 => ['pipe', 'w'],  // stdout
-        2 => ['pipe', 'w']   // stderr
-    ];
-
-    \$process = proc_open(\$command, \$descriptors, \$pipes);
-
-    if (!is_resource(\$process)) {
-        throw new \\RuntimeException(\"Failed to execute command\");
-    }
-
-    fclose(\$pipes[0]);  // Close stdin
-
-    \$output_str = stream_get_contents(\$pipes[1]);  // Read all stdout
-    \$error_str = stream_get_contents(\$pipes[2]);   // Read all stderr
-
-    fclose(\$pipes[1]);
-    fclose(\$pipes[2]);
-
-    \$return_code = proc_close(\$process);
-
-    // Combine stderr with stdout if command failed
-    if (\$return_code !== 0 && !empty(\$error_str)) {
-        \$output_str = \$error_str . \"\\n\" . \$output_str;
-    }
-
-    if (\$return_code !== 0) {
-        throw new \\RuntimeException(\"Command failed: {\$output_str}\");
-    }
-
-Benefits:
-- Streams unlimited output (no size limits)
-- Separate stdout/stderr streams
-- Proper return code validation
-- No silent truncation
-
-FOR SIMPLE CASES (Don't need return code):
-Use shell_exec() for commands where you only need output:
-
-    \$output = shell_exec(\$command);
 
     if (\$output === null) {
-        throw new \\RuntimeException(\"Command failed\");
+        throw new \\RuntimeException('Command failed');
     }
 
-Benefits:
+ADVANCED USAGE (need return code):
-- Simple one-line replacement
+Use the echo \$? trick to capture exit code:
-- Returns entire output as string (no line-by-line buffering)
-- No silent truncation
-- Drawback: Cannot get return code (assumes success if output is not null)
 
-RATIONALE:
+    \$full_command = \"(\$command) 2>&1; echo \$?\";
-exec() was designed for simple command execution in the early PHP days. Modern PHP
+    \$result = shell_exec(\$full_command);
-applications with large compilation outputs, bundling systems, and complex toolchains
-need proper stream handling. Both proc_open() and shell_exec() handle
-unlimited output correctly - exec() does not.
 
-NEVER use exec() for:
+    // Last line is the exit code
-- Compilation outputs (esbuild, webpack, babel, jqhtml)
+    \$lines = explode(\"\\n\", trim(\$result));
-- Bundler commands
+    \$return_code = (int)array_pop(\$lines);
-- Any command with potentially large output (>100 lines)
+    \$output = implode(\"\\n\", \$lines);
-- Commands where you need to see complete error messages";
+
+    if (\$return_code !== 0) {
+        throw new \\RuntimeException(\"Command failed: \$output\");
+    }
+
+WHY THIS WORKS:
+- shell_exec() returns ALL output as a string (no line-by-line buffering)
+- No size limits, no truncation, no pipe buffer issues
+- Simple and reliable
+
+IMPORTANT NOTES:
+- Do NOT use proc_open() - it's also banned (see PHP-PROC-01)
+- Do NOT try to use exec() with file redirection - just use shell_exec()
+- shell_exec() is the ONLY approved way to execute shell commands";
