01 / PRINCIPLES
Operating Principles
The standards used to decide, build, collaborate with AI and define when work is genuinely complete.
Nguyen Khai Tri · Public knowledge layer
Knowledge graph live · v1.3A personal operating system for projects, decisions & AI.
KhaiTriOS turns scattered work into a structured system: what was built, why decisions were made, how processes can be reused, and what should happen next.
Public by design. Personal memory, credentials and client-sensitive data remain in the private vault.
System map
Nine modules, one operating logic.
The public layer explains how work is approached, what was built, which practices are reusable, why decisions were made, what evidence teaches and how every record connects.
02 / PROJECTS
Project Encyclopedia
Products and systems documented through context, architecture, decisions, outcomes and lessons.
03 / PLAYBOOKS
Reusable Playbooks
Practical frameworks for performance marketing, websites, SEO, analytics, automation and delivery.
04 / DECISIONS
Decision Records
Important choices connected to context, alternatives, criteria, consequences, evidence and review triggers.
05 / LESSONS
Lessons & Evidence
Reusable learning connected to decisions, observed outcomes, confidence levels, applicability and review triggers.
06 / GRAPH
Knowledge Graph
Typed relationships make projects, playbooks, decisions and lessons searchable as one connected system.
07 / ROADMAP
Build Roadmap
A staged path from the public foundation to a private, AI-ready operating layer.
08 / CHANGELOG
Versioned Learning
Meaningful changes are recorded so the system remains traceable instead of becoming a static archive.
09 / PRIVATE AI LAYER
Protected Context
Identity, memory, internal decisions and sensitive context are prepared for AI without being published on the website.
Operating loop
Knowledge should improve the next decision.
KhaiTriOS is designed as a feedback loop rather than a document archive.
Capture
Record context, work and outcomes while they are still fresh.
Structure
Connect information to projects, domains and decisions.
Decide
Use previous trade-offs and evidence to choose faster.
Build
Apply reusable patterns instead of rebuilding from zero.
Learn
Feed results and lessons back into the system.
Current milestone
The public knowledge graph is live.
Eleven public records now share eighteen typed relationships, making the first decision-to-lesson chain and its supporting project evidence directly navigable.
