v0.6 Epic: Memory Atoms + Knowledge Graph + Descriptor Audit Bridge

This epic continues the v0.5 build-pipelines theme by layering on the long-term-memory and knowledge-graph dimensions called out in DLRS_ULTIMATE.md §"derived layer" + ROADMAP v0.6.0. Offline-first remains the default; any hosted-API access must opt in through an explicit policy gate.

Scope (10 sub-issues, one PR each)

Foundations

• v0.6: housekeeping — bump to v0.5.1, seed CHANGELOG v0.5.1 + v0.6 Draft #53 housekeeping — bump README to v0.5.1, add CHANGELOG.md v0.5.1 + v0.6-Draft entry
• v0.6: schemas/memory-atom.schema.json — atom contract #54 schema — schemas/memory-atom.schema.json
• v0.6: schemas/entity-graph-{node,edge}.schema.json — KG contract #55 schema — schemas/entity-graph-node.schema.json + entity-graph-edge.schema.json

Pipelines

• v0.6: pipelines/memory_atoms/ — extract memory atoms (paragraph + spacy backends) #56 pipeline — pipelines/memory_atoms/ (paragraph baseline + opt-in spacy)
• v0.6: pipelines/knowledge_graph/ — entity / relation extraction (regex + spacy) #57 pipeline — pipelines/knowledge_graph/ (regex baseline + opt-in spacy)

Cross-cutting governance

• v0.6: descriptor → audit/events.jsonl bridge (close v0.5 documented gap) #58 tool — descriptor → audit/events.jsonl bridge; closes the v0.5 documented gap
• v0.6: opt-in hosted-API policy gate (online_capable + --policy-allow-online) #59 policy — opt-in hosted-API gate (online_capable + --policy-allow-online)

Examples + CI

• v0.6: examples/memory-graph-demo — end-to-end memory + KG walkthrough #60 example — examples/memory-graph-demo/ end-to-end
• v0.6: pipeline tests + CI integration (batch_validate >= 14 steps) #61 CI — pipeline tests + CI integration; tools/batch_validate.py step count >= 14

Docs

• v0.6: PIPELINE_GUIDE + GAP/STATUS/ROADMAP/CHANGELOG/README refresh to v0.6 #62 docs — docs/PIPELINE_GUIDE.md + GAP/STATUS/ROADMAP/CHANGELOG/README refresh

Governance hard rules (carried over from v0.5)

1. One issue → one PR.
2. PR body MUST list Closes #N on its own line (not comma-separated).
3. PR title prefixed with the v0.6 area (feat(pipelines/memory_atoms):, chore:, docs(v0.6):, etc).
4. CI (validate + lint docs + pipelines matrix 3.11/3.12) must be green before merge; Devin Review may run after merge but does not block.

Non-goals for v0.6 (explicitly punted)

• Runtime layer (REST/WS/Realtime/3D) — v0.7+
• RBAC/ReBAC/ABAC — v0.7+
• Federated registry sync — v1.0+
• C2PA actual signing / hardware watermarking — v1.0+
• Fine-tuning pipeline (LoRA/QLoRA) — v0.7 candidate

Target completion

v0.5 → v0.6 should bring overall completion ~83% → ~88%, primarily by lifting the build-pipelines dimension (45% → 65%) and the audit dimension (70% → 80%) through the descriptor-audit bridge.
