Zentro

Collision-Free Asynchronous Sync Architecture

Utilizes Yjs CRDTs integrated over a custom Supabase transport broker layer to achieve continuous mathematical state convergence across geographically distributed clients. Users can simultaneously co-author nodes on the Tiptap rich text canvas with instantaneous micro-update propagation.

Semantic Mapping via 2D Force Graphs

Visualizes complex thought layout files natively as a interconnected database grid. The interface dynamically updates a 2D force-directed node web, reflecting real-time alterations to link topologies and tags while maintaining stable spatial orientations.

Link-Parsing Streaming Typewriter Engine

Features a specialized parsing layout inside the AI chat interface that pre-scans incoming stream buffers for incomplete markdown links. It pauses character increments until closing paren characters are confirmed over the network, fully eliminating raw syntax flashing for structural layout components.

Isolated System Prompt Sandboxing

The Knowledge Copilot API aggregates library manifests, active note configurations, and vector-matched document fragments into guarded operational blocks. It programmatically intercepts out-of-bounds queries, enforcing zero-tolerance constraints against unrelated history, general logic, or trivia topics.

Transactional Quota Tracking & Dispatch

Enforces operational guardrails through serialized RPC queries that verify credit ledgers before initiating vector inference blocks. On deduction, post-flight snapshots trigger local event broadcasts that instantly update the sidebar usage meters across active workspace viewports.

Preventing UI Syntax Flashes from Streaming Payloads

Problem: Streaming raw markdown chunks into standard typewriter states caused incomplete URLs and parenthesis markup to appear briefly as unstyled text before rendering as functional links.

Solution: Implemented a markdown link-parsing buffer layer that halts text increments the moment an opening link signature is caught, releasing the fully hydrated link component only when the closing token bounds are verified.

Securing Resource Budgets Against Infinite Loop Drainage

Problem: Asynchronous UI designs run the risk of race-conditions where rapid, concurrent client requests could trigger multiple backend AI actions before initial deductions finish saving.

Solution: Created a serialized check_and_increment_ai_credits database function that acts as an atomic lock, combining evaluation and credit deduction inside a single database transaction while forcing immediate UI inputs to step down on limit exhaust.

Confining LLM Scopes Strictly to Workspace Boundaries

Problem: Standard system definitions can easily be circumvented by prompt injection techniques, leading to out-of-bounds compute usage for non-workspace questions.

Solution: Structured an isolated multi-context layout block inside the api routing middleware that encapsulates data using explicit XML wrapper layouts, backed by a programmatic refusal directive that catches irrelevant tokens immediately.

Ensuring Layout Fluidity Across Large Note Collections

Problem: Iterating through vast structural indices to populate visual layouts or historical chat memory trees introduced noticeable interface latency on portable viewports.

Solution: Leveraged Next.js Server Components to stream initial workspace shells instantly, while mapping secondary node charts to lightweight lazy arrays that only mount when entering explicit layout boundaries.
