Second Brain (segundo-cerebro)

This repository is André's consolidated long-term knowledge base — his Second Brain.

Source of truth

  • Markdown files in this Git repository are the canonical source of truth. Every fact, decision, and piece of durable knowledge lives here as plain text.
  • Git is the source of truth for history. Do not maintain parallel changelogs; use commits and file history to understand how knowledge evolved.
  • Quartz is a read-only presentation layer only. It will later render this repository as a browsable website. Quartz never becomes the source of truth, and nothing here should be written to accommodate Quartz at the expense of the Markdown/Git model.

Daily Notes vs Daily Logs

These two directories look similar but answer different questions and have different owners:

  • Daily Notes — human-owned. AndrĂ©'s own, unedited personal record of a day. AI agents may read it when authorized but must never create, edit, or reformat it. See AGENTS for the exact rule.
  • Daily Logs — AI-owned. A structured consolidation, written by AI agents, of what happened on a given day across conversations and authorized sources.

Neither is the permanent home for important facts. Anything worth keeping beyond the day it was recorded must be consolidated into its canonical location under 10-bus/, 20-people/, 30-knowledge/, or 50-decisions/.

Business Units (BUs)

Knowledge that belongs to a domain with its own objectives and operational context lives under Business Units. The initial BUs are FamĂ­lia Oliveira Antunes, Circle, and Digital Flux AI. Each BU's internal structure reflects its own domain rather than a forced common template.

Maps of Content

Every meaningful directory exposes an index.md that acts as a lightweight Map of Content (MoC): what belongs there, what doesn't, and links to the important children. Start any navigation of this repository from the nearest index.md rather than browsing files directly.

Human-owned vs AI-owned

  • Human-owned: 01-daily-notes/ — AndrĂ©'s original record, never touched by agents.
  • AI-owned: 02-daily-logs/ — the AI's own chronological consolidation.
  • Shared/canonical: everything else (10-bus/, 20-people/, 30-knowledge/, 40-resources/, 50-decisions/) is collaboratively maintained current-state knowledge, written by AndrĂ© and/or AI agents acting on his behalf, always converging on one canonical home per fact.

How agents should start

  1. Read System and AGENTS first — they define operating rules, conventions, and retrieval strategy for this repository.
  2. Identify the likely BU or knowledge domain for the task and start from its index.md.
  3. Follow [[wikilinks]] to related entities before searching full text.
  4. Prefer canonical current-state documents over Daily Logs; consult Daily Logs only when chronology matters, and Daily Notes only when explicitly relevant and authorized.

See Business Units and Knowledge for the two main knowledge trees.
