…aph (#3221, #3222, #3223) Closes #3221, #3222, #3223. **#3221 — ClawVM-style typed page compaction (zeph-context)** - New `TypedPage` with BLAKE3 content-hash page id and `PageType` enum (ToolOutput, ConversationTurn, MemoryExcerpt, SystemContext) - Per-type `PageInvariant` trait with four implementations enforcing minimum-fidelity invariants at compaction boundaries - `InvariantRegistry` and bounded async `CompactionAuditSink` (mpsc) - `ContextAssembler::gather()` classifies every slot into a typed page and appends an audit record per compacted page **#3222 — MemReader write quality gate (zeph-memory)** - New `QualityGate` scoring three dimensions: information value (cosine similarity vs recent context), reference completeness (pronoun/deictic heuristic), contradiction risk (graph edge conflicts) - Fail-open contract: embed/LLM/graph errors yield neutral defaults - Wired into `SemanticMemory::remember()` and `remember_with_parts()` after A-MAC admission via `with_quality_gate()` builder - Disabled by default; configurable via `[memory.quality_gate]` TOML **#3223 — APEX-MEM append-only property graph for MAGMA (zeph-memory)** - SQLite migration 075: adds `supersedes`, `canonical_relation` to `graph_edges`; new `edge_reassertions` provenance table - `GraphStore::insert_or_supersede`: atomic supersession (single tx), byte-identical reassertion path, supersede depth cap (64 hops) - `OntologyTable` with ArcSwap + LRU-4096 cache for predicate normalization with LLM fallback - `ConflictResolver` with recency / confidence / llm strategies
