cjm-dev-graph-schema

Development/decision-provenance schema for context graphs: Decision, Fact-slot/Assertion, Evidence, Thread, Session, Procedure, and Entity node kinds with deterministic identity and overlay/reasoning edges — the dev-domain sibling to cjm-transcript-graph-schema for graphing a project's own evolution.

Modules

• cjm_dev_graph_schema.__init__
• cjm_dev_graph_schema.aliases — Rename-stable subject resolution (the A+aliases identity machinery).
• cjm_dev_graph_schema.identity — Deterministic node-id helpers for the dev/decision-provenance domain.
• cjm_dev_graph_schema.nodes — Typed node dataclasses for the dev schema (coarse + fine tier).
• cjm_dev_graph_schema.predicates — Typed predicates + their value-space metadata (the dedup decidability layer).
• cjm_dev_graph_schema.vocab — The reserved node-kind and edge-relation vocabulary for the dev/decision-provenance domain.

API

cjm_dev_graph_schema.aliases

• build_alias_index function — Index every entity by its key, current name, and each alias.
• resolve_subject_id function — Resolve a subject name to its entity id via the alias index (no guessing).

cjm_dev_graph_schema.identity

• assertion_node_id function — Assertion identity = (slot, canonical value, actor).

• reference_node_id function — Reference identity = (sibling graph key, foreign node id).
• section_node_id function — Section identity = (enclosing Note, heading anchor slug).
• series_node_id function — Series identity = its stable key.

cjm_dev_graph_schema.predicates

• Predicate class — A typed predicate's value-space (the contradiction decidability metadata).

• citation_value function — A citation's parts as the fact's value -- sorted keys, compact separators, blanks dropped;
• get_predicate function — Look up a predicate's value-space; exact entry first, then a prefix FAMILY
• is_approval function — Whether an assertion is approval-class (APPROVAL_CLASS — schema data, design 40622922).

• is_ordered function — Whether the predicate's values have a "later supersedes earlier" ordering.
• is_terminal function — Whether value is a TERMINAL side-state of an ordered enum (item 140981e9): off the

• resources_links function — The inverse of resources_value; a malformed value reads as no links.
• resources_value function — A source's links as the fact's value -- each link's fields sorted, the links in role then
• soft_conflict function — Whether an UNTYPED slot's active values disagree (a worklist candidate).
• traffic_of function — The inverse of traffic_value; a malformed value reads as no measure.
• traffic_value function — A traffic measure as the fact's value -- sorted keys, compact separators. Refuses a missing
