Should close FOR, but IF is on top + // Author's code: lastBlock.pair !== closerPair, so doesn't pop + // Stack STAYS: [FOR, IF] ← CORRUPTED! +endif; // Now validates against corrupted stack + // Finds IF on top → no error reported! +``` + +**Current Code (Buggy):** +```typescript +if (closerPair && stack.length > 0) { + const lastBlock = stack[stack.length - 1]; + if (lastBlock.pair === closerPair) { + stack.pop(); + } + // If it's not the correct type, don't remove anything (it's an error) +} +``` + +**Required Fix:** +```typescript +if (closerPair && stack.length > 0) { + // For specific closers, search the stack for a matching block type + // This maintains stack integrity by removing the block even when nesting is incorrect + // The validation of correctness happens in validateClosingKeyword + for (let j = stack.length - 1; j >= 0; j--) { + if (stack[j].pair === closerPair) { + stack.splice(j, 1); + break; + } + } +} +``` + +**Why This Works:** +The stack represents which blocks are still open.
