+# Implementation Plan: BaselineCompareRun model bugfix
+
+**Branch**: `feat/700-bugfix` | **Date**: 2026-02-20 | **Spec**: `specs/feat/700-bugfix/spec.md`
+
+## Summary
+
+Fix runtime crash caused by a missing Eloquent model referenced by a Filament dashboard widget.
+
+## Technical Context
+
+- PHP 8.4.x, Laravel 12
+- Filament v5, Livewire v4
+- PostgreSQL (Sail locally)
+- Tests: Pest v4 (`vendor/bin/sail artisan test --compact`)
+
+## Approach
+
+1. Identify intended storage for baseline compare runs:
+   - If a `baseline_compare_runs` table already exists, implement `App\Models\BaselineCompareRun` mapped to it.
+   - If not, align the widget to an existing persistence type (likely `OperationRun`) without changing UX.
+2. Add a regression test that exercises the tenant dashboard route and asserts a successful response.
+3. Run Pint on dirty files and run the focused test.
+
+## Risks
+
+- Introducing a new model without an existing table could still fail at runtime. Prefer minimal, compatibility-first changes.

+# Bugfix Specification: BaselineCompareRun missing model
+
+**Branch**: `feat/700-bugfix`  
+**Created**: 2026-02-20  
+**Status**: Ready
+
+## Problem
+
+Navigating to the tenant dashboard (`/admin/t/{tenant}`) throws an Internal Server Error:
+
+- `Class "App\Models\BaselineCompareRun" not found`
+
+The stack trace points to the dashboard widget `app/Filament/Widgets/Dashboard/BaselineCompareNow.php`.
+
+## Goal
+
+- Tenant dashboard loads successfully.
+- Baseline compare widget can safely query baseline compare run state without a fatal error.
+
+## Non-Goals
+
+- No UX redesign.
+- No new baseline-compare workflow features beyond restoring runtime stability.
+
+## Acceptance Criteria
+
+- Visiting `/admin/t/{tenant}` does not throw a 500.
+- The widget renders even when there are no baseline compare runs.
+- A focused automated test covers the regression.

+
+## Validation
+- [X] T030 Run Pint (dirty)
+- [X] T040 Run focused tests via Sail
