Previous approach (artfou1 DISTINCT ON no_id DESC) picked the most recent
artfou1 record, but artfou1 is a commercial reference table that may not
reflect actual current sourcing.
New approach: for each article, find the most recent reception movement
(genremvt IN (1,2)) in mvtart — this is the actual last delivery. Join
artfou1 to get the supplier code (ORDER BY datmvt DESC, af.no_id DESC to
break ties). This correctly attributes CA to whoever last physically
delivered the goods, not to a historical commercial reference.
Articles with no reception history are excluded (no INNER JOIN fallback
needed as all sold articles must have been received at least once).

DISTINCT ON with ORDER BY no_id ASC was picking the oldest supplier entry
(BAZAR 5000 historically), attributing CA to a supplier the store no longer
uses. Changing to DESC picks the most recently inserted artfou1 row, which
represents the current active supplier for each article.

artfou1 has multiple rows per article (multi-supplier), causing each mvtart
movement to be counted N times in the JOIN. Use a CTE with DISTINCT ON
(art_no_id) ORDER BY no_id to pick one canonical supplier per article,
matching the same pattern used in pgGetArticlesByFournisseur.

- page.tsx: move formatCA into client component (functions not serializable
across server→client boundary in Next.js — root cause of 500)
- client.tsx: remove unused BarChart2 import
- client.tsx: replace useSearchParams() with direct URL construction to
avoid Suspense boundary requirement
- pg-ff-client: use OR conditions instead of IN() for Drizzle compatibility

- pg-ff-client: replace ANY(ARRAY[...]) with IN(...) for Drizzle compatibility
- sidebar: change Analytics icon from BarChart2 (duplicate) to TrendingUp

EOF
- pg-ff-client: add pgGetCaByFournisseur() and pgGetCaByNomenclature()
returning CA TTC per site and month for monthly N vs N-1 comparison
- analytics/page.tsx: server component with pivot logic to reshape raw
query data into store-separated columns (292/579/total) with evolution %
- analytics/client.tsx: client controls (mode dropdown, month selector)
and responsive table with color-coded evolution badges
- sidebar: add "Analytics" link to navigation
Features:
- Switch between "Fournisseur" and "Nomenclature" views
- Select any month for comparison vs same month prior year
- Columns split by store: Frouard/Nancy (292), Houdemont (579), Total
- Each store shows: CA this month, CA N-1, evolution %
- Footer totals row matching sum of detail rows
- FR locale currency formatting (€)

- score-engine: add hard guard (wQty=0 && wCa=0 → score=0) before any
calculation to prevent edge cases (residual margin, percentile rank)
from producing non-zero scores on unsold articles
- score-engine: set inactivity=24 when product has never sold, so the
regularityMultiplier penalty (0.3) is correctly applied instead of 1
- pg-ff-client: remove erroneous negation on qte_recue — entry movements
have positive qtemvt in the DB, negating them produced negative values
that failed the > 0 check, hiding all entrées in tooltips and modals
