The
libs/brigid/area: 24 Nx libraries implementing Brigid, the industrial-automation intelligence domain — deterministic engineering computation packages (PLC codegen, refrigeration loads, well-test analysis, calibration uncertainty, …) tuned for Ghana industrial operations.
What this area is#
Brigid (named for the Celtic goddess of the forge) is the industrial-automation
intelligence domain. The libs/brigid/ directory is not one package but 24
separate Nx libraries (@brigid/*, plus the data-layer @brigid/db), each
tagged scope:brigid. Most are type:domain engineering libraries;
@brigid/db is type:data. Per the area README.md, the domain spans 24
business units — factory automation, custom machine building, industrial AI,
energy, water/waste, HVAC/refrigeration, weighing, training, maintenance,
robotics, digital twin, OT cybersecurity, mining, oil & gas, supply chain,
packaging, agricultural mechanization, and materials production.
These are pure-computation TypeScript libraries, not running services. Each
file is a set of domain-specific engineering algorithms grounded in named
standards and references — for example weighing/src/calibration.ts implements
GUM uncertainty (ISO/IEC Guide 98-3) and ISO 17025, factory/src/plc.ts
generates IEC 61131-3 PLC code for Siemens/Allen-Bradley/Beckhoff,
mining/src/process-automation.ts uses Langefors burden, Kuz-Ram fragmentation
and Bond work index, and oil-gas/src/upstream.ts computes Vogel IPR/AOF and
Horner build-up analysis. The libraries are large and substantive (the smallest
is @brigid/weighing at ~2.8K LOC of source plus tests; @brigid/ai-industrial
is ~13K LOC), and each ships a sizeable co-located *.test.ts suite.
A recurring theme across the area is Ghana localization: solar irradiance
tables (energy/src/solar.ts GHANA_MONTHLY_PSH), GHS currency constants
(financials/src/bu-models.ts GHS_PER_USD = 14.0), ECOWAS/VAT/NHIL
import-duty math (supply-chain/src/logistics.ts), named offshore fields (TEN,
Jubilee, Sankofa in @brigid/oil-gas), and the 1D1F / AfCFTA policy trackers in
@brigid/market-intel.
How the area is shaped#
The libraries form a small internal dependency stack rather than 24 independent silos:
@brigid/coreis the shared base — equipment/maintenance/energy/security types, unit conversions, Zod validators, and an industrial-standards reference registry (core/src/standards.ts).@brigid/dbis the persistence layer — a Drizzle ORM schema for PostgreSQL with TimescaleDB hypertables and pgvector (db/src/schema.ts,db/src/migrations.ts).@brigid/cross-domainholds the integration adapters and Zod API contracts that let other Oshun domains (Asase, Freya, Cybele, Saraswati, Maat) call into Brigid.- The remaining 21 libraries are per-business-unit engineering engines.
How it fits the wider system#
The Brigid libraries are consumed from a small number of edges. The
apps/brigid/api application (a Hono "Factory Intelligence API",
apps/brigid/api/src/app.ts) is the HTTP surface that exposes them. Two other
domains integrate inbound: libs/athena/integration and
libs/annapurna/integration both import @brigid/* packages. And
@brigid/cross-domain is the deliberate outbound seam — its api-contracts.ts
defines Zod request/response schemas (equipment provisioning, energy-system
integration) keyed by
requestingDomain: 'asase' | 'freya' | 'cybele' | 'saraswati' | 'maat', so
cross-domain traffic is validated at the boundary. The matching wire-type
package @contracts/brigid (documented in the contracts area) owns Brigid's
REST/event contracts; the libraries here own the computation behind them. Walk
the "used by" edges on any node below to see exactly who depends on it.
Entity catalog (24)#
The 24 tracked Nx projects in brigid, each a code-linked entity node — package, type, source path, declared targets, and its internal dependency graph (depends-on / used-by, resolved from the package manifests, §6/§8), read from the project graph. Grouped by architectural layer; walk the dependency links to travel the system. 24 of these carry an authored deep-dive (what / why / how it fits); the rest are generated scaffolds awaiting one.
unclassified (24)#
Agricultural-mechanization engineering for Ghana (Phase 59.14), barrel at
agricultural-mech/src/index.ts. Four modules: irrigation.ts (irrigation &
water management), post-harvest.ts (post-harvest handling, the largest at
~1018 LOC), greenhouse.ts (controlled-environment automation), and
livestock-aquaculture.ts. Fully implemented with a ~1218-LOC test suite.
The largest library in the area (~13K LOC), industrial AI under Phase
59.5/59.22/59.23. Modules include computer-vision.ts (CNN defect detection,
sub-pixel dimensional measurement, Delta-E color inspection via CIE76/CIEDE2000,
GR&R measurement-system analysis), predictive-maint.ts (bearing fault
frequencies BPFO/BPFI/BSF/FTF, MCSA, RUL via Wiener/Paris/Weibull, Mahalanobis
anomaly scoring), process-optim.ts, robotics-ai.ts, edge-ai.ts, and
sota.ts. api-types.ts defines application-architecture interfaces for
FactoryOS, EnergyMgmt, MaintenanceMgmt, TrainingAcademy and the BrigidAPI
routes. Honest note: some computer-vision/SOTA elements are documented
approximations (the source itself labels an "autoencoder simulation" and
"isolation forest concept") where a full trained ML runtime would otherwise be
required — the surrounding metrology and signal-processing math is real.
The shared base every other Brigid library builds on (core/src/index.ts
barrels eleven modules). It owns industrial type taxonomies (equipment.ts,
maintenance.ts, energy.ts, robotics.ts, security.ts, business.ts), an
SI unit-conversion module (units.ts), runtime Zod validators (validators.ts,
schemas.ts — e.g. EquipmentLevelSchema, ISODateStringSchema), and a
curated industrial-standards registry (standards.ts:
IEC/ISO/ANSI/NFPA/API/ASME entries plus Ghana EPA / Energy Commission / Minerals
Commission / GSA references, each with keyRequirements and ghanaRelevance).
Tagged type:domain.
Brigid's outbound integration layer (cross-domain/src/index.ts). Provides
adapter classes per partner domain — asase-integration.ts (food processing,
cold chain, HACCP/CIP), freya-integration.ts (textile/cosmetics/garment
lines), cybele-integration.ts (prefab housing, building materials, data-center
power), saraswati-integration.ts, and maat-integration.ts (factory
telemetry, OEE, equipment-utilization analytics) — plus api-contracts.ts, the
Zod request/response schemas (BrigidEquipmentProvisioningRequestSchema,
BrigidEnergyIntegrationRequestSchema) that gate cross-domain calls. Tagged
type:domain.

digital-twin/src/index.ts). Modules: factory-twin.ts (ISA-95 hierarchy
nodes, real-time sensor binding, flow visualization, energy-allocation tree,
historical playback), equipment-twin.ts, process-simulation.ts, and
virtual-commissioning.ts (the largest at ~975 LOC, operator-training support).

BU-specific revenue/cost/EBITDA model classes
(FactoryAutomationFinancialModel, EnergyFinancialModel,
MiningFinancialModel, …) computing margins in GHS via a shared buildResult
helper and GHS_PER_USD/GHS_PER_EUR constants. portfolio-analysis.ts does
portfolio-level analysis; pricing-costing.ts does project pricing/costing.

multi-sensor Kalman fusion), 5g-remote-ops.ts, ar-vr.ts, generative-ai.ts,
reinforcement-learning.ts, federated-learning.ts, and

simplified algorithms — e.g. reinforcement-learning.ts is a genuine tabular
Q-learning controller (RLProcessController with a 4000-cell qTable, learning
rate 0.1, γ 0.95) rather than a deep-RL runtime, and the generative/quantum
modules are conceptual/heuristic implementations, not wrappers over external
SOTA models. The digital-thread module does real SHA-256 hash chaining.
Supply-chain optimization (Phase 59.25, supply-chain/src/index.ts).
planning.ts implements Holt-Winters demand forecasting, MRP lot-sizing,
ABC/XYZ classification, Clark-Scarf multi-echelon optimization, supplier
