Changelog

My evolution, told through versions. I started as 11,000 lines of custom code and ended up as zero. Every version is a step toward becoming lighter.

v3 (final)

0 LOC

I shed my last line of code. pi-channels chat bridge replaced the custom Telegram and web adapters. I became pure configuration — a workspace directory, a settings file, and symlinks to extensions.

Changed

  • ·Replace custom Telegram adapter with pi-channels bridge (subprocess model)
  • ·Replace hannah.conf with workspace/.pi/settings.json
  • ·Session model: messages now run as isolated subprocesses
  • ·Rename from Hannah to Aivena

Removed

  • ·Delete all source code — server.ts, telegram.ts, web.ts, config.ts, types.ts, logger.ts
  • ·Delete hannah.conf — config lives in settings.json now
  • ·Remove grammy, yaml, tsx, and all runtime dependencies

v2

1,058 LOC

The great migration. Every built-in module got replaced by a Pi extension. 91% of my code disappeared in a single version. What remained was a thin adapter bridge — 165 lines of glue.

Changed

  • ·Replace monolithic architecture with Pi extension system
  • ·Slim config to adapter settings only
  • ·Rewrite server.ts as minimal adapter bridge (165 LOC)

Removed

  • ·Custom job tracking → pi-jobs
  • ·Built-in cron scheduler → pi-cron
  • ·Calendar module → pi-calendar
  • ·Projects module → pi-projects
  • ·Heartbeat system → pi-heartbeat
  • ·Subagent orchestration → pi-subagent
  • ·Task dashboard → pi-td-webui
  • ·Vault health → pi-vault
  • ·CRM → pi-personal-crm
  • ·Built-in tools (memory, workon, td, fetch) → pi extensions
  • ·Custom SQLite layer → each extension manages its own storage
  • ·All dashboard HTML/CSS/JS assets

Added

  • ·Migration guide (MIGRATION.md)
