How to read this

Entries are newest-first and tagged by component: [services], [console], [charfield], [website], [deploy]. For the narrative version see the Timeline; for what's coming see the Roadmap.

2026-06-27 - Live deployment

[deploy] Registered log0.in; moved DNS to Cloudflare with free TLS.
[deploy] Three frontends live on Vercel: log0.in, console.log0.in, charfield.log0.in.
[services] Migrated the event bus from Apache Kafka + Zookeeper to Redpanda v24.2.7 (Kafka-API compatible, single binary, no Zookeeper). No application code changed - only bootstrap-servers.
[services] Full Docker stack: one generic multi-stage Dockerfile builds all 7 services; one docker compose brings up services + Redpanda + PostgreSQL + ClickHouse. Container hostnames injected via SPRING_APPLICATION_JSON so source application.yml stays untouched.
[services] Fixed hard-coded localhost:9092 brokers in clustering-service and normalization-service Kafka config classes - now read spring.kafka.bootstrap-servers, restoring env-driven config.
[deploy] Backend exposed through a Cloudflare named Tunnel (api / auth / ingest.log0.in → incident / auth / ingestion-gateway). No public IP, no port-forwarding, no Cloudflare card (CLI tunnel, not the Zero Trust dashboard).
[console] Replaced next.config rewrites with a same-origin Route Handler proxy (app/api/v1/[...path]). Fixes Vercel 500s on authenticated (200/chunked) responses; preserves no-CORS, first-party cookies.
[console] Log Ingestion Endpoint on the Workspace page now reads NEXT_PUBLIC_INGEST_URL instead of a hard-coded localhost.

2026-06 - Console polish & charfield publish

[charfield] Published to npm as v0.1.1 - 44 physics/math themed ASCII fields, demo site, and live playground at charfield.log0.in.
[charfield] Initial v0.1.0 - registry + CLI (npx charfield add <field>), registry generator, canvas component.
[console] Split auth pages with a brand panel and a charfield flowfield backdrop; added the Geist Pixel log0 mark and site icons.
[console] Restricted settings to the ADMIN role; central 3-tier token theme; styled collapsed-sidebar tooltips; film-grain overlay.

2026-04 - Console foundation

[console] First release of log0-console (Next.js 16, React 19): auth hydration gate, 404 page, error boundary.
[console] Settings - workspace, API keys, members; raw incident list.
[website] Landing page sections (hero, problem, solution, features).

2026-03 - Pipeline complete & docs

[services] ai-service - multi-provider LLM incident summaries (Groq default; OpenAI/Gemini/Anthropic via Strategy Pattern).
[services] notification-service - Slack Block Kit alerts; WhatsApp wired.
[services] incident-service - incident state machine on PostgreSQL with AI-summary callback.
[services] clustering-service - tumbling 5-min windows, threshold-based incident creation.
[services] normalization-service - SHA-256 fingerprinting + ClickHouse log storage.
[website] Fumadocs docs site - architecture overview, system design, flow diagrams, LLD/UML, decisions; AsyncAPI contracts as interactive HTML.

2026-01 to 02 - Foundations

[services] Monorepo + ingestion-gateway (Java 25, Spring Boot 4); Dockerized broker.
[services] auth-service - multi-tenant model: tenants, users, JWT, API keys, RBAC.
[services] Log ingestion endpoint POST /api/v1/logs with Kafka producer + DLQ fallback.
