From 137a588ed08a71ff0757dd3d9dd7edd24aafc9f0 Mon Sep 17 00:00:00 2001 From: jordan Date: Mon, 2 Feb 2026 17:44:54 -0700 Subject: [PATCH] feat: Concept hierarchy (Phase 5D) - ConceptPath, source schemes, AliasStore MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements hierarchical subject identifiers with scheme-based source tier inference: - ConceptPath type with parse/wire_format, leaf/parent, prefix matching - SourceScheme registry mapping schemes to default SourceClass tiers: - rfc://, fda://, ietf:// → Regulatory (Tier 0) - peer://, pubmed:// → PeerReviewed (Tier 1) - code://, wiki:// → Expert (Tier 3) - blog://, anon:// → Anecdotal (Tier 5) - AliasStore for cross-scheme entity resolution (bidirectional indexing) - API endpoints for concept operations - Battery tests 8, 9 & 10 for concepts, aliases, and advanced signatures - Go SDK updates for concept types and signing Completes Phase 5, advancing to Phase 6 (Distributed Writes).
