Lattice AI v3.6.0 — Knowledge Graph First

Lattice AI v3.6.0 — Knowledge Graph First

Lattice AI is not a model-personalization system. It is a Digital Brain
Platform. v3.5.0 stabilized the foundation; v3.6.0 makes the Knowledge Graph the
primary architecture. Models are replaceable. Knowledge is durable. Your
Knowledge Graph is the durable asset, and every data source now converges into it.

v3.5.0 carry-over audit

A full carry-over review (docs/CARRYOVER_AUDIT_v3.6.0.md) classified every open
v3.5.0 item as blocking / non-blocking / obsolete. Result: zero blocking
items. Settled postures were preserved — Vercel stays a landing/download/demo
surface (never the runtime), OIDC stays RSA-only, and the legacy /account and
/admin pages stay out of scope. The one honest v3.5.0 gap — KG ingestion not
firing tool hooks — is closed in this release.

Knowledge Graph First architecture

All user data sources flow through a single unified model:

source → extraction → normalization → metadata → chunking → entity detection →
relationship detection → embedding → Knowledge Graph → RAG / agents / memory / search

No new data source bypasses the Knowledge Graph; none creates an isolated silo.

What's new

Unified ingestion pipeline

• New latticeai/services/ingestion.py — one IngestionPipeline.ingest()
  entrypoint normalizes every source (file, folder, web URL, browser tab,
  text/markdown/note/code) into a single IngestionItem.
• Idempotent by content hash — re-ingesting the same content links/updates
  instead of duplicating.
• Routed through the shared dispatch_tool lifecycle so pre_tool/post_tool
  hooks fire on data ingestion (closing the v3.5.0 gap); a blocking pre_tool
  returns an honest status="blocked".
• Each item records source_type, source_uri, content hash, captured_at,
  modified_at, owner/workspace, permissions, graph node + chunk IDs, and
  embedding/indexing status.

Entity & relationship model

• Six new first-class entities: Source, Repository, Meeting,
  Organization, Workflow, Agent.
• Eight new relationships: indexed_from, modified_by, belongs_to_project,
  part_of, discussed_in, decided_by, generated_by, used_by_agent.
• Additive and lossless — from_legacy() normalizes the new aliases (incl. Korean
  verbs); unknown types still fall back to CONCEPT/MENTIONS. Schema kept
  extensible. Documented in docs/kg-schema.md.

Browser & web ingestion (as graph inputs, not standalone features)

• POST /api/browser/read-url — the local runtime fetches a public URL, extracts
  readable text, stores it as source_type=web_url. Fails gracefully (HTTP 422)
  on blocked / login-required / non-HTML pages.
• POST /api/browser/ingest-current-tab — accepts a sanitized, size-limited
  payload from the local browser extension as source_type=browser_tab.
• Manifest V3 Chrome/Edge extension scaffold under browser-extension/ — sends
  the current tab to the local runtime only (127.0.0.1). No external server, no
  cloud upload.

Export / import / backup / restore

• Logical export/import (versioned JSON: nodes/edges/chunks/sources/provenance +
  schema/projection/embed-dim header; merge/replace + dry-run; refuses newer
  schemas).
• Binary backup/restore (VACUUM INTO snapshot incl. vector embeddings + blob
  directory, sha256 integrity-checked).
• latticeai/services/kg_portability.py + /api/knowledge-graph/{export, export-file,import,backup,restore,portability,provenance}. Local-first — no
  cloud service required.

Provenance & auditability

• New ingestion_provenance table + record/get/list/provenance_stats methods —
  an append-only trail making every node explainable (origin, time, pipeline,
  embedded, linked, duplicate, agent-used).

Runtime / hook safety

• New ingestion, browser, and web paths respect the v3.5.0 lifecycle standard via
  dispatch_tool. docs/RUNTIME_HOOK_COVERAGE_v3.6.0.md records coverage with no
  regression from v3.5.0.

UI

• The Knowledge Graph view is recast as your digital brain with tabs: Explore
  (entity/relation mesh), Status (graph + ingestion health), Sources
  (provenance — where every node came from), Capture (read a URL into the
  graph), and Backup (export / import / backup).

Validation

• Unit tests: full suite green (tests/unit/), including new suites for the
  schema, ingestion pipeline, provenance, browser routes, portability, and v3.6.0
  hook coverage.
• npm run lint, npm run check:python, npm run build, and release-artifact
  validation pass; v3 frontend lint 64/64.

Not in scope (settled)

• Vercel remains landing/download/demo only — never the runtime.
• OIDC remains RSA-only unless intentionally expanded.
• Legacy /account and /admin pages remain outside the v3 SPA view set.

External publishing

None. No publish to npm, PyPI, VS Code Marketplace, Open VSX, Docker Hub, or
Vercel was performed by this release.
