## pi-memory 0.4.2

- Author: **Jay Zeng** (jayzeng)

Lean Memory 0.1 was a thin context-injection adapter over the complete pi-memory
runtime. Version 0.2 adds its own project-scoped storage, seven tool definitions,
local keyword search, recovery records and snapshot lifecycle to enforce isolation.
It reuses pi-memory's `parseScratchpad`, `serializeScratchpad`, `scratchpadAdd`,
`scratchpadToggle`, `scratchpadClearDone` and `forgetBlocks` helpers unchanged.
Those helpers preserve free-form notes and implement entry-aware deletion; credit
for them belongs to Jay Zeng. The familiar tool names and Markdown organization
also originate from pi-memory.

The unchanged upstream package is bundled as a pinned dependency for these helpers;
its global extension factory and qmd integration are not invoked. Its original
copyright and license remain intact. No upstream endorsement is implied.

Upstream pi-memory also credits https://github.com/skyfallsin/pi-mem for inspiration.
