SmartCon360's real claim: unifying four methodologies

The hardest question to close this series: are AWP, Lean, Takt and LBMS actually linked in one product, or just four separate layers sitting side by side? Because value only emerges if they truly integrate.

Real intersections in the code (with Prisma relations):

• AWP → LBS: WorkPackage.cwaLocationId → Location, a real foreign key.
• Within AWP: Activity (IWP).cwpId → WorkPackage (CWP), a real FK; when a constraint is resolved, linked IWPs are released automatically (cascade + audit log).
• LBMS → Takt: ZoneTradeQuantity.quantity × Trade.productivityRate derives man-hours; the calibration loop updates that rate from field data.
• Lean → Takt: the LPS lookahead is fed by the planned dates of IWPs; those dates come from the wagon.
• AI context: the agent reads IWP + constraint + location + wagon joined in a single query.

Closed this week:

• TaktZone ↔ Location is now a first-class Prisma relation (TaktZone.location ↔ Location.taktZones). The FK column already existed; the relation definition was added and verified across the four schemas — the ORM now joins zone → location.

Planned additions (roadmap):

• WorkPackage.wbsNodeIds is currently a Postgres array; a junction table that pushes WBS↔package integrity down to the DB level is planned.
• Flowline persistence and DRL optimization are in the next phases.

I wrote these 8 parts evidence-first: no polish, just the file. Which mechanism would you like me to dig into in the next series?
