Requirements
Framework
The governing requirements that define the architectural envelope within which the adopted Foundational Survey Fabric Specification and all future compatible evolution must remain.
The Foundational Survey Fabric Requirements Framework defines what BitPangea’s permanent spatial reference architecture must preserve, permit, exclude, and prove. These requirements establish the architectural envelope within which the later mathematical specification must operate.
The framework does not itself select the final mathematics, addressing scheme, subdivision model, implementation technology, or higher-layer architecture. Instead, it preserves the permanent conditions that any candidate design must satisfy without contradiction while protecting the boundary between foundational spatial reference and the responsibilities of higher Architecture domains.
Atlas Working Principle Do not choose the architecture because it looks elegant. Choose it only after it survives the requirements.
Architecture Boundary Rule Protect the boundary. Do not design the layer above from the layer below.
Requirements Structure
Foundational Purpose and Scope
Defines the minimum permanent purpose of the Foundational Survey Fabric, the separation between canonical spatial reference and higher Architecture responsibilities, the proper reach of immutability, extension without downward mutation, and preservation of unknown future use.
Findings #1–#6 →Addressability, Canonical Meaning, and Refinement
Defines addressability for every location representable under the canonical Survey mathematics, permanent canonical meaning, refinement by extension, implementation-independent interpretation, semantic separation between space and entities, and one foundational reference shared by higher systems.
Findings #7–#15 →Authority, Consensus, and Specification Evolution
Defines the separation between technical reproducibility and canonical authority, and how the governing standard may evolve without renumbering, relocating, or reinterpreting established spatial truth.
Findings #16–#17 →Mathematical Ontology and Survey Domain Structure
Defines the Survey Fabric’s mathematical ontology: finite canonical Survey Domain, extensible precision, canonical references, planar ground, exact mathematics, semantic neutrality, canonical extents, and the distinction between foundational reference capacity and higher-layer World meaning.
Findings #18–#33 →Native BitPangea Measurement and Orientation
Defines Pang-based scale and area, canonical spatial separation, BitPangea-native directions, one permanent origin, one global canonical frame, and exact agreement between address, measure, and orientation.
Findings #34–#43 →Geometry, Topology, Measurement, and Spatial Operations
Defines exact continuity, spatial predicates, transformations, measurement, geometric composition, normalization, normative serialization and interchange, equivalence, precision handling, comparison, connectedness, and other Survey-layer spatial operations.
Findings #44–#77 →Finite Knowability, Computability, and Conformance
Defines finite representability, exact computability, minimal primitives, hidden-state independence, termination, controlled complexity, exact canonical states, the mandatory conformance core, and staged readiness gates for mathematical design, prototype testing, and canonical adoption.
Findings #78–#85 →Together, these seven sections preserve the requirements-level definition of the Foundational Survey Fabric as a minimal, exact, finite, planar, semantically neutral, BitPangea-native spatial reference architecture.
The complete framework governs the constraints that any FSF mathematical design, Conformance system, Reference Vector corpus, implementation, and adopted Specification must satisfy. Canonical adoption does not replace these Requirements; it confirms that the adopted Specification has survived the required traceability, conformance analysis, adversarial testing, and independent implementation obligations.
The adopted Foundational Survey Fabric Specification operates inside this Requirements envelope rather than rewriting it. FSF-SPEC-1.0 now establishes the production mathematical baseline, including CRPC, ECEM, Point / Segment / SCPE geometry, exact rational predicates, deterministic normalization, FSF-CJSON-1.0, the right-handed canonical frame, and counterclockwise-positive rotation.
The canonical Survey Domain is the closed axis-aligned square D = [-1,000,000,+1,000,000]² Pang, with governed half-span H = 1,000,000 Pang. The governed production placement envelope is P = [-500,000,+500,000]² Pang. Broader capability outside the adopted production profile—including unrestricted Boolean / composite-result closure—remains reserved unless later introduced through governed Specification evolution.
Current Standing
Requirements Integrity Audit complete. Findings #1–#85 remain the governing Requirements set with preserved wording and boundaries. FSF-SPEC-1.0 is canonically adopted, FSF-CJSON-1.0 is the canonical machine serialization for the adopted production profile, and Conformance and Reference Vectors remain subordinate proof frameworks. The Requirements therefore remain current and governing without themselves becoming the Specification or adoption authority.
