TNB 8f4ed8a306 docs: TallyFlow Scout marketing + Edge/Print/Capture feature refresh

Review tallyflow-assets-iot (TallyFlow Scout v0.5.3): Collect, Verify,
Locate with Edge remote reader / offline CSV locate. Clarify Scout does
not replace Core Assets. Refresh Edge, Print parent-container and multi-
unit identity notes, Capture share/offline/barcode notes, architecture,
use cases, capabilities, and website drafts after src/ repo pulls.

TallyFlow Architecture

Diagram: TallyFlow-Architecture-Diagram.html

Overview

TallyFlow is built around Core as the central hub that owns the database, plus field and site modules. Scout is an Edge companion handheld, not a sixth Core-connected peer equal to Assets.

1. Core (Central)

Core Backend (Go) positioned in the center — provides the REST API
Core Web UI (Vue.js) on the left — consumes the Core API
Auth Service — handles login and SSO support
Owns MongoDB (assets, tags, photos, zones, events)
Single API integration point for Core-connected components
Handles configuration, reporting, and orchestration

2. Assets (Mobile)

Flutter native mobile application (tallyflow_mobile)
Lightweight inventory, geiger-style seek & find, enrollment, zone moves, scan-and-print
Communicates with Core via REST/WebSocket API
Not the same product as Scout

3. Print

Flutter + Rust implementation
Zebra ZPL-compatible label printing and RFID encoding
Includes Print UI for configuration
Can also be driven directly via the Print API
Can register assets directly with Core
Parent container EPC namespace (SDG RAIN assignment 8000); multi-unit retail companion AI 21; register preflight against duplicate identities

4. Capture (PhotoTag)

Native mobile applications (iOS/Android) + web
Associates photos with barcodes, work orders, and metadata
Focused on quality control and visual documentation
Public share collections on web (controlled external access)
Sends data to Core via API where deployed

5. Edge

Rust-based site edge service (repo tallyflow-iot; product name TallyFlow Edge)
Fixed RFID readers (Impinj, Zebra, ATID ATF862 / Invengo XC-RF861 where supported)
Remote reader REST API for handhelds
Unified multi-reader feed → CSV / REST / AMQP → Core (optional)
Keyboard wedge, ops UI, MCP read tools
Can integrate with ERP systems without requiring Core

6. Scout (Edge companion handheld)

Flutter app TallyFlow Scout (repo tallyflow-assets-iot)
Collect / Verify / Locate
Submits to Edge remote reader API (or CSV offline); Locate works offline
Does not replace Assets and does not talk to Core as the asset app

MongoDB is not a standalone component — it is fully owned and managed inside Core.

Data Flows

Assets, Print, Capture → Core: Solid lines (primary Core flows)
Scout → Edge: Solid (remote reader / site feed)
Edge → Core: Dashed line (optional, event-driven AMQP/etc.)
Print additionally supports asset registration back into Core
Core Web UI communicates with Core Backend via the same API used by other Core clients

Core-connected modules interact through Core’s REST API layer. Edge/Scout may operate standalone for site RFID programs.
