- Build on Cogitave Core Learn the harmonic core that every Cogitave product and agent shares: the Cogitave Core node and edge model, Cogitave Query, the native MCP interface, and how products project their state into a single queryable graph. By the end you'll be able to read the estate the same way humans and agents do. Day 0: this path is scaffolded - the module bodies are authored in a later content phase.
- Cogitave engineering standards Learn the standards floor that governs every repository in the Cogitave estate: the AGENTS.md rules, naming, commits and versioning, testing and quality, API design, configuration, secure SDLC, CI/CD, and observability and reliability. By the end you'll be able to make changes that pass the org gates by default. Day 0: this path is scaffolded - the module bodies are authored in a later content phase.
- Get started with Cogitave Massar Massar is the guardian agent that lets an authorized Cogitave operator open an audited terminal session on a customer device with no inbound port and no VPN. Understand the dial-out security model and how a session is bridged, then install, verify, and cleanly remove the agent on Linux and Windows using the real installers.
- Introduction to Cogitave Diyar Diyar is Cogitave's edge-autonomous platform for operating regulated field devices, where the device stays the sole authority over safety and evidence and each industry ships as a signed, pluggable solution. Understand what Diyar is, why safety and evidence stay local to the device, and how a device becomes a solution through signed profiles, verdict engines, and app packages.
- Patterns and golden paths Learn to build the Cogitave way: reuse first, discover before you generate, start from the patterns catalog, inherit a repository's complete ruleset through the project baseline, and use the decision guides for database, infrastructure, and model selection. By the end you'll reach for the named artifact before writing anything new. Day 0: this path is scaffolded - the module bodies are authored in a later content phase.
- Design and version a Cogitave API Shape a clean, consistent API against the Cogitave API design standard - resources, standard methods, typed errors, cursor pagination, idempotency - then version and deprecate it under the versioning policy so no consumer is ever broken without consent.
- Apply the naming standards Name a new identifier, file, repo, or branch the way the estate does - keyword-first, no redundant prefix, cased by role - and tell a functional keyword apart from a product codename, so your first artifact passes the naming gate by default.
- How a device becomes a Diyar solution Diyar turns a physical device into a certified solution through layered signed documents and firmware-compiled registries, not through custom code written per customer. A signed device profile configures the edge's hardware at boot; a certified verdict engine - a frozen product engine or one of the generic function blocks - decides pass or fail; and a three-document app package computes, offline, exactly what a device is authorized to observe, operate, or actuate. The module walks each of these three layers as they exist in the Diyar edge platform today, closes with one worked solution (ISPM-15) built entirely on that machinery, and states plainly where a capability is proven only against internal example fixtures rather than a field deployment - because that distinction is part of what you need to evaluate the product honestly.
- Read the pipeline that ships your change Follow a change from a pull request through the canonical CI stage set to a gated production deploy - the ordered gates a pipeline runs, why CI is the real gate, and how the deployment model promotes one signed artifact dev to staging to prod.
- Commits and versioning Write Conventional Commits whose type, scope, and breaking marker drive Semantic Versioning; see how release-please turns merged commits into a human-approved Release-PR, changelog, and tag; and how the trunk-based, protected-main model gates every release.
- Manage configuration and secrets Classify every value as a constant, a deployment parameter, or a secret; load configuration through the standard precedence chain, parsed once and fail-closed; and keep secrets out of git by referencing them at runtime and committing only encrypted-at-rest .env files.
- Core model fundamentals Explain why Cogitave Core is one canonical property graph that humans and agents both query, what its node/edge model and identity scheme actually are, and why ADR-0001 chose a labeled property graph as the substrate.
- Safety and evidence in Diyar Cogitave Diyar drives real industrial heat-treatment equipment without depending on a network connection, and this module explains the three mechanisms that let it do so safely and provably. First, a layered, hardware-first fail-safe design where every failure path — a wedged CPU, a blind sensor, a power cut, a lost serial cable — falls back to the heater being off, never the reverse. Second, a request model where the cloud and any remote client can only ask the edge to start a run; the edge alone verifies and can refuse, and there is no primitive anywhere in the system that lets a remote party force actuation. Third, an evidence pipeline that journals every reading locally before it is ever published, chains it so tampering becomes detectable, layers a Merkle history tree on top so completeness can be proven without shipping an entire run's history, and lets the cloud independently reconcile what it received rather than trusting the edge's word. Throughout, the module states plainly which parts of this are built and verified today versus named, not-yet-shipped follow-ups.
- Install and operate the Massar agent This module installs and operates the Cogitave Massar agent: the small, cross-platform binary a customer runs on a device so an authorized Diyar operator can dial in for an audited remote terminal, with no inbound port and no VPN. You install it with the CLI installer for your OS - install.sh on Linux, install.ps1 on Windows - confirm it is verified and running as a service, trace a session from open to close, reproduce the whole relay locally with the project's own dev harness, and remove it cleanly when you are done. Two facts are stated plainly rather than glossed over: today's supported install targets are Windows and Linux only, and every end-to-end proof described here is the local dev harness, not a production Diyar deployment.
- The native MCP interface to Core Read Core's MCP interface as the source of truth for how an agent queries the estate - why the surface is native rather than adapted, the protocol contract it commits to, and the tools and resources you call.
- Observability and reliability Instrument a service with OpenTelemetry-spec traces, metrics, and logs, understand why agent traces are kept as evidence, and reason about reliability through SLIs, SLOs, error budgets, and the policy that turns a spent budget into a release freeze.
- Operate from Day 1 Describe the Day 1 operating model - the pinned inner loop and the flow-based outer loop - state the parity contract that keeps the inner loop honest, name Cogitave's flow-based ways of working and why ADR-0025 chose it over Scrum, and explain why the human gate stays an exception inside the flow.
- Project products into Core See how content projects into Cogitave Core as typed, content-addressed nodes rather than separate silos, and how the fact registry's cite-not-restate rule and fact-drift scanner keep one owner per fact across the estate.
- Query the estate with Cogitave Query Learn how Cogitave Query resolves a request against the canonical graph - lexical BM25 and dense HNSW vectors fused by Reciprocal Rank Fusion, a graph-aware rerank and ranking signals, and the bounded, read-only query_graph profile agents call directly.
- Reliability and SRE Reason about a service's reliability targets the way the reliability standard does - set an SLO from the user's journey, compute the error budget it buys, and operate the service against that budget with burn-rate alerts, sustainable on-call, a toil cap, and the freeze that stops shipping when the budget runs out.
- Respond to incidents Walk the incident-response flow end to end - detection, severity declaration, single-commander roles, containment through a runbook, communication, recovery, and the blameless postmortem - and see how business continuity and disaster recovery extend the same discipline to a region loss or a destructive event.
- Run agentic operations Explain what agentic operations means at Cogitave, state the draft-vs-act rule that decides when an agent acts unattended versus when it stops for a human, and name the real fleet of scheduled and operations agents that run the estate.
- Build with the secure SDLC State the security baseline - threat modeling, least privilege, and IAM - and follow the secure development lifecycle that shifts security left, so each stage of a change carries its own security gate instead of a check bolted on at the end.
- Test to the standard and pass the quality gate Learn how Cogitave tests a change - the pyramid/trophy shape, the diff-coverage and mutation gates, flaky-test quarantine, the runnable harness, and the craftsmanship review bar - so you can test your own change and get it through the gate.
- Agent identity and capabilities Every Cogitave agent acts under its own identity inside an explicit least-privilege capability grant, in a sandbox, with every action recorded as evidence. What that model guarantees, and where a human is still required.
- What Yuva is Yuva is a from-scratch, agent-native sovereign unikernel in no_std Rust, with formally verified leaves and a boot that fails closed. What it is for, how it is verified, and exactly which parts are not live yet.
