ai
AI & agent behavior
Understand how Abbey and ABI route requests, produce local responses, and expose bounded checks.
Local deterministic routing and completion are implemented; model quality requires separate evaluation.
Research
Ideas with their evidence attached.
Six tracks, the public notes on each, and the nested implementation cases that pin those claims to source. Citations stay on the page. Borrowed benchmarks do not.
Tracks
Start from the subject, not a paper pile.
Six research areas, from AI assistance and durable memory to evidence selection and integration. Start with practical applications, then inspect the sources, implementation status, and limitations.
Put these ideas in context: explore ABI, Abbey, WDBX and Quasar, or choose a starting point.
wdbx
WDBX memory & retrieval
Durable records, searchable vectors and inspectable retrieval for applications that need continuity.
Rust persistence, HNSW search and episode-store components are implemented.
sea
SEA evidence selection
Select a bounded set of relevant records before assembling an assistant context.
Eight-signal selection, task-specific scoring and bounded prompt assembly are implemented.
gpu
GPU & compute
Inspect native vector-operation support and explicit CPU fallback.
CPU vector operations and optional macOS Metal DOT dispatch are implemented.
mcp
MCP integrations
Expose bounded ABI operations through a documented tool interface.
The twelve-tool stdio JSON-RPC contract is implemented.
tui
TUI & operator tools
Inspect local runtime state and explore session-based agent interactions.
The diagnostics dashboard and agent REPL are implemented.
Topics
Precise language. No borrowed benchmarks.
If a number is not produced by a repository test or a documented artifact, it does not appear here.
Memory architecture
Episodic records with WAL, MVCC, causal DAGs, and content addressing. Memory is a substrate, not a chat log with embeddings glued on. Applies to WDBX, ABI.
Retrieval
WDBX implements exact and layered-HNSW retrieval with a pluggable scoring seam; evidence-weighted retrieval remains unimplemented. Applies to WDBX.
Distributed systems
Reference cluster replication and read repair are in source. They do not establish production sharding or hosted authority. Applies to WDBX.
Model orchestration
Deterministic persona routing, template completion, and source-defined MCP tools. Model execution and quality require separate evidence from the selected runtime path. Applies to ABI.
Privacy and provider boundaries
Browser workspace documents and vault notes use localStorage. Configured website model requests and Quasar generation have separate provider and data boundaries. Applies to Quesar, Abbey, ABI.
Provenance and trust
Content addressing, signatures, and causal history expose record commitments and relationships. They do not establish the truth or evidential reliability of a record. Federation evidence is separately authorized. Applies to WDBX, Abbey.
Synchronization
Synchronization requires separate implementation and signed-device qualification. The browser vault uses localStorage; the native CloudKit availability plugin does not implement vault synchronization. Applies to Quesar, mobile.
Interoperability
Research scope: consistent product, persona, and claim-provenance vocabularies across integrations, with implementation and UI semantics evaluated separately. Applies to Quesar.

Implementations
Nested cases. Each one names the source it depends on.
These sit under /research/implementations. They are implementation readings, not extra benchmark claims.

A six-layer architecture for evidence-aware AI systems
Quesar organizes interface, orchestration, retrieval, acceleration, storage, and audit as distinct layers so that evidence and runtime claims can be traced to the component that actually supports them.
ai · wdbx
A private document pipeline with explicit fallback behavior
The private Quesar application implements bounded ingestion, workspace-scoped extraction and search, and consent-gated model access while making degraded retrieval behavior visible instead of silently changing providers.

Mobile Vault persistence across CloudKit and local fallback
The Quesar mobile Vault keeps one CRUD contract while selecting either the user's private CloudKit database or an encrypted local SecureStore fallback and exposing the selected backend to the application.

Quasar as a bounded repository-generation loop
Quasar couples an Anthropic tool loop to a narrowly constrained project filesystem, producing a local application through inspectable read, list, and write operations rather than granting an unconstrained shell.
