- Add date? field to BSRRecord (ISO string YYYY-MM-DD)
- processBSRExcel now extracts and stores the Date column as an ISO date
(handles both Excel serial numbers and string dates)
- VendorDataView groups chart data by date (daily) when dates are available,
falling back to weekly buckets — eliminates straight-line charts caused
by only 2 weekly data points

- Fix critical regex bug: /\\d+/ was matching literal '\d' instead of
digits, causing all rows to be rejected (week always = 0)
- Add VendorCSV format support: 'Top Level Category (Rank)', 'Date', etc.
- Derive ISO week number from Date column when no Week column exists
- Process all sheets (not just first) to handle multi-tab workbooks
- Log column names on load to aid future debugging

- Rewrite api/fetch-bsr.ts to proxy BSR.xlsx from the Dropbox URL,
matching the same pattern as fetch-buybox.ts and other data sources
- Add /api/fetch-bsr proxy in vite.config.ts for local dev

VendorDataView was refactored to receive BSR data as a prop but App.tsx
was not updated to pass it, causing the component to crash on undefined
and show a blank screen. Also fixes supabase.ts type errors and removes
dead code.

- Change getWeekStartSunday to getISOWeekMonday for timestamp calculation
- Ensures week alignment between data aggregation and ISO week range calculation
- Fixes incorrect treatment_after average calculation
Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
- Add ISO week calculation functions (getISOWeek, getISOWeekMonday, calculateISOWeekRange)
- Expand experiment dates to full ISO weeks (Monday-Sunday) instead of exact date ranges
- Use actual data.length for averaging metrics instead of theoretical durationWeeks
- Baseline now takes same number of complete weeks immediately before experiment
Fixes incorrect units sold average calculation (was 6.5, now correctly shows 4.33 for 13 units over 3 weeks)

The generic regex /sale/i in ads column detection was matching "Advertising Cost
of Sales" (the ACOS % column) before reaching "7 day total sales" (the actual
attributed sales amount). This caused attributedSales30d to receive the ACOS
percentage instead of the real sales value, making experiment ACOS = 0 or 100%.
- Replace /sale/i with specific regexes: /\d+\s*day.*sale/i, /total\s+sale/i, etc.
- Replace /cost/i with regexes that exclude "cost of sales" columns
- Replace /unit/i with specific regexes for unit columns
- Add diagnostic logging for ads Excel column headers and first-row values
- Revert ACOS 100% fallback (root cause now fixed)

- Change ?? to || for salesAds/units/revenue in weekly aggregation to guard against NaN
- Add || 0 fallback to ads-only records in mergeSalesAndAdsData
- Fix parseCurrency to check isNaN on all EU-format return paths
- Handle ACOS edge case: cost > 0 with adRevenue = 0 now returns 100% instead of 0%
- Add diagnostic console logging to computeDiD for data flow tracing

Allow pasting multiple ASINs separated by spaces in any MultiSelectDropdown
search field and pressing Enter to auto-select all matching options.
Also switch ads CSV/Excel parsing to header-based column mapping for
robustness across different file formats.

Replace undefined input-field CSS class with explicit Tailwind dark theme
classes (bg-slate-800, border-slate-700, text-slate-200) to prevent white
background on form fields.

Replace the basic CRUD experiment tracker with a scientifically rigorous A/B testing system:
- Add DiD analysis engine (services/experimentAnalysis.ts) that computes treatment vs control
group comparisons across 7 metrics (units, sessions, CVR, CTR, ROAS, revenue, ACOS)
- Implement Bayesian verdict system (Winner/Loser/Inconclusive) using posterior probability
with normal CDF approximation (Abramowitz & Stegun erf, no external deps)
- Build counterfactual time series for trend charts (actual vs estimated without change)
- Rewrite ExperimentsView as single component with 3 inline sub-views (list, detail, create)
replacing the previous modal-based ExperimentDetail and ExperimentForm
- Add control group support, change annotations (before→after diffs), and SEO experiment type
- New types: ExperimentChangeAnnotation, DiDMetricResult, DifferenceInDifferencesResult,
ExperimentVerdict
- Simplify App.tsx by removing experiment modal state (5 useState hooks eliminated)

Use a hardcoded ALL_MARKETPLACES list instead of deriving from current
filtered data, so Amazon UK is always available even when viewing PAN-EU.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Each experiment now tracks which marketplace (Amazon DE, UK, etc.) it
applies to. The form defaults to the currently active marketplace filter,
and the delta % calculation filters by both product line and marketplace.

processTrafficExcel was only reading the first sheet, missing data from
year-based sheets (e.g., "2025", "2026"). Now iterates all sheets with
auto-detection of column layout, matching the processAdsExcel pattern.
