+# shadow_economy_intensity: float [0.0, 1.0]
+#   Measures the gap between formal (Commission-audited) and real economic
+#   activity at each node. This is NOT a crime index. A system with
+#   intensity 0.8 has roughly 20% of its economy visible to the Assembly
+#   lattice audit trail — not because 80% is criminal, but because 80%
+#   is conducted through channels the Commission does not count.
+#
+# The official_coverage_ratio signal (D-181 signal 7) derives directly
+# from this initialization parameter:
+#   official_coverage_ratio ≈ 1.0 - shadow_economy_intensity
+# A system with intensity 0.7 → official_coverage_ratio ≈ 0.3, meaning
+# the Commission's economic picture understates reality by roughly 3×.
+#
+# Seeding algorithm:
+#   1. Look up geographic band by hop_distance_from_gateway
+#   2. Sample uniformly within [band.intensity_min, band.intensity_max]
+#   3. Apply active modifiers (additive, order-independent)
+#   4. Clamp result to [0.0, 1.0]
+#   5. Apply system_override if present (replaces formula result entirely)
+#
+# Sol (the currency) is the shadow medium of exchange — untraceable,
+# no issuer to cooperate with enforcement, no lattice audit trail.
+# Sol is NOT a currency zone; it is modeled as a shadow commodity (D-171).
+# Shadow_economy_intensity controls how active the Sol shadow layer is:
+# higher intensity → higher Sol black-market premium above Tractus par.
+#
+# Contraband types (canonical, from D-174):
+#   - Unlicensed lattice components (D-037)
+#   - Sol-denominated luxury goods (Earth imports)
+#   - Unregistered commercial intelligence
+#   - Unlicensed re-embodiment
+#
+# Decisions: D-174 (shadow economy layer), D-171 (Sol as shadow commodity),

+# THE COMPACT FRAMING — READ THIS BEFORE MODIFYING (D-174)
+#
+# The Compact of Westphalia's shadow economy is PRINCIPLED ECONOMIC
+# RESISTANCE to Assembly currency friction on enforcement costs.
+# It is NOT frontier lawlessness. This distinction is architecturally
+# critical for NPC dialogue, faction reactions, and the inspect verb.
+#
+# WHY THE COMPACT HAS HIGH INTENSITY:
+#
+# Commission certification fees and enforcement assessments are
+# Tractus-denominated. Compact systems operating in the Mark zone pay
+# these costs at the ~3% cross-zone conversion rate (D-172). Over time,
+# rational actors in Compact systems structure their transactions to avoid
+# Commission audit requirements: Mark-denominated domestic trade, supply
+# chains routed through Compact customs arrangements, Sol for cross-zone
+# transactions that benefit from anonymity. None of this is criminal.
+# It is economically rational behavior in a zone where Commission authority
+# is both politically contested and economically punitive.
+#
+# Intensity in Compact systems reflects the GAP IN THE ASSEMBLY'S
+# ACCOUNTING, not the behavior of the people. A Compact system at
+# intensity 0.75 is not more criminal than an inner system at 0.1 —
+# its economy is simply less legible to the Commission because its
+# residents have decided, as a matter of political principle, not to
+# organize their commerce around Assembly certification requirements.
+#
+# CONTRAST — WHY FRONTIER SYSTEMS HAVE HIGH INTENSITY:
+#
+# Frontier systems (hop 10+) have high intensity for structurally
+# different reasons: genuine Commission absence, sparse enforcement,
+# actual contraband networks, unlicensed re-embodiment operations, Sol
+# black markets filling gaps in formal medical and technical supply.
+# The frontier shadow economy is a CAPACITY GAP (the Commission cannot
+# physically reach here, not a deliberate choice to operate outside it.
+#
+# WHAT THIS MEANS FOR THE INVESTIGATE VERB (Phase 3):
+#
+# An investigator who treats Compact opacity as criminality will lose
+# trust rapidly and find closed doors. The Compact's "shadow" economy
+# is visible to anyone who operates within Compact commercial frameworks —
+# it is only opaque to the Commission's audit tools. Gaining access to
+# a Compact system's real economic picture requires building relationships
+# within the Compact network, not finding criminal informants.
+#
+# An investigator who treats frontier opacity as principled politics will
+# miss actual criminal networks operating in the enforcement vacuum. The
+# frontier's shadow economy includes actors who are genuinely dangerous
+# and genuinely hidden. Finding them requires different tools than finding
+# Compact commerce.
+#
+# The inspect verb should reflect this distinction. Framing it as a
+# binary "formal/informal" misses the politics. The right question is:
+# "Informal by whose accounting? Principled non-compliance or operational
+# concealment?"

+# Yttermark — outermost dead-end in west_reach, hop 17, MARK_PRIMARY
+intensity = 0.91
+rationale = """
+Yttermark is the outermost settled system in the west_reach corridor — a dead-end
+at hop 17, where the name (Swedish: 'outermost boundary') describes the lived
+reality. Commission authority is not theoretical here; it does not exist as a
+meaningful concept. There is no periodic enforcement. There is no Commission
+inspector. There is no certified supply chain for most transaction categories.
+
+The intensity of 0.91 reflects the operational reality: formal-channel commerce
+requires infrastructure that Yttermark does not have and cannot obtain at
+commercially viable costs. This is the extreme of the frontier enforcement vacuum.
+
+The PRINCIPLED framing still applies — Yttermark was founded from Compact-culture
+communities and its self-governance is organized and stable, not anarchic. The
+high intensity does not indicate disorder; it indicates comprehensive Commission
+invisibility. The official_coverage_ratio at Yttermark (≈ 0.09) means the
+Commission's economic picture of the system is built almost entirely on what the
+two gates transmit in transit manifests. Everything else — all local commerce,
+all service provision, all production and consumption at the single inhabited body
+— is invisible to the Assembly.
+
+The intensity cap of 0.90 from the compact_membership modifier is exceeded here
+by the accumulation of enforcement vacuum and dead-end topology effects, plus
+the base deep_frontier range. Pipeline: clamp to 1.0 if formula exceeds it.

+intensity = 0.88

+Near-identical conditions to Yttermark. Grenzstein sits one hop inward from the
+outermost settled node and shares the structural characteristics of the far
+frontier: no Commission presence, no certified supply alternatives, Compact-culture
+self-governance, and through-route topology connecting to Yttermark.
+
+The through_route topology provides one degree of differentiation — Grenzstein is
+not a dead-end, which means slightly higher transit volume and slightly more
+commercial interaction with systems inward. Through-routes create informal customs
+functions (goods pass through, some transit commerce develops) that partially
+substitute for formal Commission infrastructure. This keeps intensity marginally
+below the dead-end Yttermark, but the conditions are structurally equivalent.
+
+The name is deliberate and ironic — the community at the boundary stone is not
+at a boundary of civilizational capacity but at a boundary of Commission legibility.
+They govern themselves, they trade through the Compact, they maintain the gate.
+They simply do not report to anyone who would file Commission paperwork.

+# Bout du Chemin — 'End of the road', west_reach, hop 15, MARK_PRIMARY
+intensity = 0.85
+rationale = """
+'End of the road' is the literal translation and the accurate description. At hop
+15, Bout du Chemin was the furthest point of the settled corridor before Grenzstein
+and Yttermark extended the reach. Its founding name reflects that original status.
+
+Through-route topology connecting to Grenzstein means Bout du Chemin serves as an
+informal transit node for goods moving between the inner corridor and the truly
+outer frontier. The shadow economy here includes a transit function that the two
+outermost systems do not have: goods are moving through, not just being produced
+and consumed locally.
+
+This transit function introduces a layer of Sol-denominated brokerage that makes
+Bout du Chemin slightly more commercially sophisticated than the two deeper systems.
+The actors here who are managing the informal transit economy are experienced. They
+know how far Commission authority reaches (not here), what the exchange premium on
+Sol is at this depth, and what can be moved through a system where no one is
+counting. The intensity of 0.85 reflects this: high but not maximum, because the
+transit sophistication creates pricing discipline that pure enforcement-vacuum
+systems lack.
