Gap analysis: GAPS.md + fix critical runtime bugs in reports and models

[Copilot]

Full codebase audit requested to surface unused, incomplete, and broken functionality. Findings documented in GAPS.md; four runtime-crashing bugs fixed as part of the same pass. GAPS.md reflects only the remaining open issues — fixed items have been removed from the document.

GAPS.md — Analysis Document

Covers 50 modules across:

• Stubs & placeholders — code with explicit "TODO/replace later" comments and "Coming Soon" views
• Missing features — zero implementation in any layer (Return/RMA, User Logs, Guest Cart, Product↔Attribute assignment, API)
• Orphaned/legacy files — StockService (never imported, references non-existent fields), Product::barcode_data (noted legacy in comment)
• Tech debt — no route-level RBAC, large controllers, default seeder credentials
• Feature completeness matrix — ✅/⚠️/❌ per module with a prioritised action plan

Runtime Bug Fixes

Missing Eloquent relationships

User model had no relationships defined at all, causing ReportController::packetCount() and userSales() to throw on every visit:

// app/Models/User.php — added
public function orders(): HasMany        { return $this->hasMany(Order::class, 'user_id'); }
public function packedOrders(): HasMany  { return $this->hasMany(Order::class, 'packed_by'); }
public function dispatchedOrders(): HasMany { return $this->hasMany(Order::class, 'dispatched_by'); }
public function deliveredOrders(): HasMany  { return $this->hasMany(Order::class, 'delivered_by'); }

Product model was missing purchaseItems(), also used in reports:

public function purchaseItems() { return $this->hasMany(PurchaseItem::class); }

Stock report — non-existent columns and N+1

stockReport() referenced remaining_quantity, purchasing_price (columns that don't exist on PurchaseItem) and called inventoryUnits() in a loop. Rewritten to eager-load and use actual column names (purchase_price), with the Blade view updated to match.

// Before (crashes + N+1)
$products = Product::with(['purchaseItems' => fn($q) => $q->where('remaining_quantity', '>', 0)])->get();
$item->remaining_quantity * $item->purchasing_price  // neither column exists

// After
$products = Product::with([
    'variants.unit',
    'purchaseItems.inventoryUnits' => fn($q) => $q->where('status', 'available'),
])->get();
$item->inventoryUnits->where('status', 'available')->count() * ($item->purchase_price ?? 0)

All four fixed issues (missing User relationships, missing Product::purchaseItems, broken stockReport query, broken stock report view) have been removed from GAPS.md since they are no longer outstanding. The feature completeness matrix has been updated accordingly — Stock, Packet Count, and User Sales reports now show ✅.

This section details on the original issue you should resolve

<issue_title>Identifying gaps</issue_title>
<issue_description>Check everything and should identify any unused functionalities, i mean which are not front facing at this moment, which needs to be developed, which files needs to be deleted if obsolete which files need to be completed with the full process implemented in the admin dashboard if backend done or halfway done and needds more things to complete, so much think to the max with the best knowledge pursue in development as the best model in the world by most people. And give me a full doc created MD or something with everything after maximum research, so I know how to proceed, so that's your task: research, analyse, and tell me.</issue_description>

So, based on your committed files, you have fixed some critical issues, so those things are not bug issues anymore as you have fixed them. So, in your gaps.md you don't have to mention fixed ones, makes sense? Cause they're fixed. So, are you mentioning them or not? @copilot

Correct — GAPS.md has been updated in commit 099e8bc. The "Critical Runtime Bugs" section has been removed entirely since all four bugs were fixed in this PR. The downstream references were also cleaned up:

• Removed §5.3 Stock Report (fixed), §6.1 Packet Count (fixed), §6.2 User Sales (fixed)
• Removed §8.1 User Model relationships (fixed) and §8.2 Product purchaseItems (fixed)
• Removed Priority 1 "Fix Runtime Bugs" from the action plan — remaining items are re-numbered starting at Priority 1
• Updated the feature matrix: Stock, Packet Count, and User Sales reports now show ✅

The document now only reflects what still needs to be done.
