* 🧠 The Master Memex

This is the central hub for our knowledge management system, synthesizing three core methodologies:
- *Atomic Notes (Zettelkasten):* For evergreen, interlinked, atomic knowledge.
- *GTD (Getting Things Done):* For actionable task tracking and project execution.
- *PARA:* For high-level directory organization (Projects, Areas, Resources, Archives).

* The Architecture

Our workspace is strictly divided into these functional zones:

- [[file:0_inbox/README.org][0_inbox]]: The zero-friction capture point for raw thoughts and tasks.
- [[file:1_daily/README.org][1_daily]]: Immutable chronological logs and fleeting notes (YYYY-MM-DD.org).
- [[file:2_notes/README.org][2_notes]]: The Atomic Notes (Zettelkasten). Atomic, concept-based, interlinked notes.
- [[file:3_drafts/README.org][3_drafts]]: Works in progress, essays, and active synthesis.
- [[file:4_published/README.org][4_published]]: Final outputs and static snapshots of completed work.
- [[file:5_projects/README.org][5_projects]]: Active, time-bound efforts with a clear definition of done.
- [[file:6_areas/README.org][6_areas]]: Ongoing spheres of responsibility (e.g., Health, Finances).
- [[file:7_resources/README.org][7_resources]]: External reference material and raw literature notes.
- [[file:8_archives/README.org][8_archives]]: Cold storage for completed projects and inactive items.
- [[file:9_system/README.org][9_system]]: System configuration, AI skills, and automation scripts.

* Core Workflows

** 1. Capture (Anytime)
Everything enters the system via \`0_inbox\` or as a Fleeting Note in \`1_daily\`. Zero friction, no filtering.

** 2. Nightly Distillation (The Scribe)
An automated AI sub-agent reads the daily captures and extracts conceptual thoughts into evergreen, atomic notes in \`2_notes\`, leaving the original daily logs untouched.

** 3. Weekly Maintenance
Review active projects, clarify inbox items into actionable GTD tasks, and explore the Atomic Notes (Zettelkasten) graph to merge concepts and forge new connections.
