Long-Term Interstellar Expansion & Network Growth

Seeding daughter colonies and weaving a single, operator-controlled interstellar civilisation

The requirement cards on this page govern. A new colony is not a second command chart. Oversight is at light delay. FPL-v1 is an upgrade path.

Inter-Planetary Link Ship • Guildford, Surrey, UK

1. Purpose

To define the functional requirements for the seamless, chronological integration of every new colony into the growing interstellar network, with the first stable portal link (IPLS-FPL-v1) as the non-negotiable binding infrastructure that prevents remote-mission stressors and enables multi-century expansion.

2. Core Expansion Principles

  • On arrival the ship joins the 3.1.19 network. FPL-v1 is an upgrade path. Oversight is at light delay.
  • Network growth shall follow the same universal modular platform (3.2) and chronological sequence used in Sol, ensuring zero vendor lock-in and full operator ownership.
  • Technology Supersession Protocol (TSP-v1) shall be applied to all legacy assets arriving via generation ships or early seeding missions.

3. First Portal Link as Network Backbone (IPLS-FPL-v1)

Functional Requirements — Ongoing Portal Network Operations (IPLS-FPL-NET-v1)

  • FPL-v1 is an upgrade path. The population and traffic at which a link becomes a mesh are unset.
  • High-bandwidth quantum-secure comms + limited matter transfer for personnel, critical spares, and cultural exchange (Communication Systems 3.1.12).
  • Real-time integration with Governance Frameworks (3.1.11 & 5.1), Psychological & Social Systems (3.1.9), and Digital-Life Habitats (3.1.22) to eliminate isolation stressors permanently.
  • Fail-operational with triple-redundant nacelle and PGEDS-v1 power systems; automated pinhole-probe monitoring.
  • Local command authority retained at all times — portal use remains operator-controlled, never autonomous.

4. Daughter-Colony Seeding & Replication

Once the primary portal link is stable and the first hollowed asteroid base is operational, the colony shall begin construction of its own colony-seeding ships (3.1.17) using local ISRU and on-site manufacturing (3.1.13). Each daughter colony shall repeat the full arrival sequence, including immediate establishment of its own IPLS-FPL-v1 link.

5. Interstellar Trade, Logistics & Supply Chain

  • Standardised PIS-v1 cargo protocols for instantaneous transfer of high-value goods, personnel, and information across the network.
  • Interstellar logistics hubs co-located with major portal nodes, using universal modular platforms and automated warehousing (3.1.14).
  • Network Standards (3.1.19) shall govern all data formats, power protocols, and interface versioning to ensure centuries-long interoperability.
  • TSP-v1 shall be invoked automatically for any asset whose performance is superseded by newer portal or drive technology.

6. Long-Term Network Evolution

The portal mesh shall grow organically: each new colony becomes a new routing node. Continuous frontier monitoring (Frontier Annex 4.5) shall trigger TSP-v1 upgrades across the entire network without disrupting operations or crew consent.

Long-Term Interstellar Expansion Mandate

Requirement: Every new colony shall be integrated into the growing interstellar network immediately upon establishment of the first stable IPLS-FPL-v1 portal link, following the same universal modular platform and chronological sequence used in Sol. On arrival the ship joins the 3.1.19 network under IPLS-3.1.17-005. FPL-v1 and PIS-v1 are upgrade paths. FPL-v1 has no defining card. What counts as a stable link is unset under IPLS-4.2-005. What integration into the network requires is unset. Command follows the IPLS-5.1-002 chart. A new colony is not a second command chart. Oversight is at light delay. Activation of a portal waits for operator consent under IPLS-5.1-002. The sequence follows IPLS-4.2-009. Which Sol cards bind the restarted sequence is unset. Hand-over follows IPLS-4.2-010. The priority scheme that Tier-1 belongs to is unset. On loss of link, life-preserving functions continue inside the IPLS-5.1-002 envelope. The IPLS-3.1-014 hold applies to other actions. T is unset.

Continuous Frontier Monitoring & TSP-v1 Triggering

Requirement: Each colony shall maintain a continuous frontier-monitoring link to detect ≥2× performance or safety improvements, automatically triggering TSP-v1 evaluation across the network. The source monitored and the path that carries it are unset. Entanglement is not a link. Relay is at light delay. The 4.5 cards are not yet repaired. The metric, baseline, and measurement basis for the 2× threshold are unset. A trigger can start evaluation and cannot grant supersession. Supersession waits for operator consent under IPLS-5.1-002.

Local Command Authority Retention

Requirement: Each colony shall retain full local operator command authority at all times; portal use and network decisions remain under explicit local consent, never autonomous. Command follows the IPLS-5.1-002 chart. A new colony is not a second command chart. Hand-over does not move command of irreversible acts off the IPLS-5.1-002 chart. What hand-over transfers is unset under IPLS-4.2-010. Irreversible acts follow IPLS-5.1-002. Reversible and life-preserving actions act inside the IPLS-5.1-002 envelope and are logged and reported to the operator. Activation of a portal waits for operator consent under IPLS-5.1-002. An ASI is never an operator. Rights follow IPLS-5.1-003 and do not include operator authority. Whether representatives' consent is also required is unset. Overrides follow IPLS-3.1.4-007 and confer no operator authority. Who holds the local veto, and what it can stop, are unset. The holder follows the IPLS-5.1-002 succession. A seized credential is not consent. The interface follows UMP-OPERATOR-001, which does not define it. Oversight is at light delay. On loss of link, life-preserving action continues inside the IPLS-5.1-002 envelope. Other governance actions hold under IPLS-3.1-014. T is unset. Whether a link whose delay exceeds T counts as loss of link is unset under IPLS-4.1-006. The pass criterion for the local versus network authority simulation is unset.

Graceful degradation and field repair follow UMP-DURABILITY-001. Degradation order and the output floor are unset. Whether a network node is a UMP core module is unset. Whether a network node is life-critical is unset. Life-critical systems remain at the 500-year figure in IPLS-3.1-016. Each step of growth that is seeding, replication, or portal activation waits for operator consent under IPLS-3.1.4-006 and IPLS-5.1-002. TSP-v1 readiness criteria are undefined under IPLS-3.1-016. Supersession waits for operator consent under IPLS-5.1-002. Backward compatibility follows IPLS-3.1.19-002. Mesh topology follows IPLS-4.3-002. Paths per link are unset.
