tegwick 574bb11db6 feat(example): add supply-chain-vsm composition demo (S3.5)
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.

# Safety Stock
## Definition
Inventory held in excess of expected demand to buffer against supply and
demand uncertainty. Safety stock represents capital deliberately kept
unproductive — not expected to be consumed in normal operations — in order
to preserve operational continuity when actual demand or supply deviates
from forecast. The optimal safety stock level balances inventory holding
cost against stockout cost.

## Supply Chain Domain
Capital Management
## VSM Assignment
S3 — Safety stock is a management-level capital allocation decision. The
question of how much safety stock to hold is a resource management choice
that trades off capital efficiency against operational resilience, made at
the S3 (management/control) level.
## WoN Concept
Accumulation of Stock — Smith describes the accumulation of stock as a
prerequisite for productive activity: you cannot employ workers until you
have stock to sustain them. Safety stock is a modern instantiation of this
logic — productive continuity requires a buffer of stock to absorb
variability, just as Smith's pre-capitalist household needed a reserve before
it could specialise its labour. Both represent capital held in reserve against
contingency rather than deployed in production.
