Reference Corpus Statistics: document frontier

Source and coverage

• Source: research/corpus/statistics.md
• Canonical ID: missing; path-derived frontier identity used
• Lifecycle status: draft
• Artifact type: research-document
• Version: 0.1
• Confidence: not declared
• Inclusion rule: explicit authority/current-state dependency
• Analysis unit: CORPUS-100

Phase 1 — knowledge extraction

• Primary objective: Characterize 100 knowledge artifacts across identity, capability, lifecycle, and composition.
• Primary claims: The corpus covers diverse artifact identities and capabilities. Most current entries are established artifacts.
• Supporting evidence: The source's declared references and the co-analyzed records listed in the analysis-unit frontier.
• Methodology: Batch-based single-analyst characterization under FEMS-1.
• Accepted/current findings: The corpus contains 100 indexed artifacts.
• Rejected or unsupported findings: Current frequency distributions are validated population estimates.
• Assumptions: The sample is sufficiently representative. Labels are reliable despite single-analyst coding.
• Limitations: All characterizations are draft; capability assignments are provisional; composition is sparse.
• Known uncertainties: Inter-rater reliability; Sampling bias; Label stability; Primitive saturation.
• Declared headings inspected: Reference Corpus Statistics; Corpus Size; Identity Distribution; Capability Distribution; Lifecycle Distribution; Batches Completed; Current Measurement Standard; Known Limitations.

Phase 2 — unresolved unknowns

• Inter-rater reliability
• Sampling bias
• Label stability
• Primitive saturation

Phase 3 — adversarial challenge

The corpus is operationally treated as an evidence base while its statistics explicitly describe all characterizations as draft.

Evidence that would materially change this assessment includes a completed independent replication, a preregistered negative control, a matched causal comparison, a governance disposition, or a demonstrated failure of the measurement and integrity instruments relevant to this source.

Top five traceable opportunities

The opportunity records contain source sections, challenged assumptions, supporting evidence, dependencies, methodology, outputs, and success criteria. Repeated opportunities are semantic links to one repository-wide record rather than duplicated records.
