wiki: design the business layer (session, tariff, permit, vision, shift, ops)
Pivot from the hardware/integrity layer to the parking operation. All
wiki-only; no code yet. Core principle throughout: business entities are
projections over the signed append-only event log, never mutable tables.
New concepts: parking-session, tariff (composable/versioned, FX-ready),
shift (manned-only Z-report), capacity-occupancy, validation-discounts,
reporting-analytics, clock-integrity, ticket-encoding, anti-passback.
New entities: permit, opencv-anpr-service, blocklist.
Decisions: session-model, vision-service (host-side ANPR + vehicle
verification; scoped AGPL exception for the isolated service).
Updates: append-only-event-chain (new event types + vision witness),
local-jwt-auth (drop 8h expiry -> until logout; code change pending),
lpr-camera (host-side recognition supersedes edge-AI), standing-decisions
(AGPL exception), open-questions (+FX, +pay-station money corners, backup).
Deferred + flagged: intercom/help-call, receipts/refunds/change, FX engine,
lane topology (#1).
