Not resurrection. Not immortality. Just love that still responds.

This series explores a question that became urgent after a cancer diagnosis: What survives us, and how do we design for it?

The Long Echo is both a philosophy and a practice. The philosophy: our digital artifacts—conversations, code, writing, bookmarks—can be preserved in ways that remain accessible and meaningful across decades, even when the original software is gone. The practice: a set of tools and principles for making it happen.

The Core Insight: Graceful Degradation

Systems should fail progressively, not catastrophically:

Level 1: Full functionality  → Rich apps with semantic search and beautiful UIs
Level 2: Database queries    → SQLite direct queries (app gone, database remains)
Level 3: File search         → grep through JSONL files (just text tools)
Level 4: Human reading       → Markdown, HTML (readable without any tools)
Level 5: Ultimate fallback   → Plain text in notepad

Every tool in the Long Echo ecosystem exports to formats that work at every level. When your children want to search your conversations in 2074, they won't need the original software. They won't even need the original database. Plain text survives everything.

The Constraint That Clarifies

A cancer diagnosis is, among other things, an optimization constraint. It doesn't change what matters—it clarifies it. These posts and tools emerged from that clarity:

The goal isn't to live forever through code. It's to leave work that others can continue, understand, and build upon. Not digital immortality—just good engineering for an uncertain future.

The echo doesn't need to be loud. It just needs to be findable.
