Demonstrates infospace composition: the Wealth of Nations infospace is used as a discipline, applying Smith's economic framework as a lens to analyse modern supply chain management concepts. New example: examples/supply-chain-vsm/ - infospace.yaml binding WoN as discipline (../infospace-with-history) - 3 source documents: coordination mechanisms, capital & inventory, market structure (~400 words each, original content) - supply-chain-entity-schema-v1.0.md with WoN Concept required section - won-mapping-schema-v1.0.md with Conceptual Continuity rating - artifacts/won-reference/core-entities.md — 12 curated WoN entities for injection as discipline context - 8 hand-crafted entity files demonstrating LLM output format - 3 mapping files with full rationale and VSM inheritance chains - Viable: YES (5/5 thresholds) Key mappings demonstrated: Demand Signal → Effectual Demand (Strong, S2) Vendor-Managed Inventory → Division of Labour (Strong, S1/S2) Just-in-Time Inventory → Circulating Capital (Strong, S1/S3) Bullwhip Effect → Natural Price (Moderate, S2) Platform Intermediary → Merchant Capital (Strong, S2/S4) Monopsony Power → Combination of Masters (Strong, S3*) Platform fix: entity_parser.py now recognises ## Supply Chain Domain as a domain alias for ## Economic Domain, enabling composed infospaces to use their own domain section name. Tutorial §13 rewritten with real commands, real output, and the full mapping table from the demo. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# Single-Source Dependency
|
|
|
|
## Definition
|
|
|
|
A supply chain condition in which a buyer relies on one supplier for a
|
|
critical component or material with no readily substitutable alternative.
|
|
Single-source situations arise from supplier specialisation, geographic
|
|
concentration of competent producers, or deliberate buyer policy
|
|
maximising scale economies with a preferred partner. During disruptions,
|
|
a single-sourced supplier in a critical category temporarily possesses
|
|
monopoly-like pricing power, as the buyer has no alternative and demand
|
|
is inelastic in the short run.

|
|
S4 — Single-source dependency is an intelligence failure at the S4 level:
|
|
the supply chain's environmental scanning has not identified and mitigated
|
|
the concentration risk. Resolving it requires S4 action — supplier
|
|
development, geographic diversification, or technology substitution.
|
|
|
|
## WoN Concept
|
|
|
|
Monopoly in Trade — Smith argues that monopolists charge the highest price
|
|
buyers will bear, and that this price is always above the competitive level.
|
|
A single-source supplier during a supply disruption is a temporary
|
|
monopolist: buyers cannot immediately switch, demand is inelastic, and the
|
|
supplier can extract above-normal prices. Smith's analysis of how monopoly
|
|
restricts supply and raises price applies directly to the disrupted
|
|
single-source scenario, even though in normal conditions the same supplier
|
|
may operate competitively.
