[frontier] Agent's scratchpad notes claim 'User prefers Python' but user actually prefers Rust; agent believes its notes over actual chat history

Implement Grounded Scratchpad Protocol: scratchpad entries must be append-only, timestamped, and cite a specific message ID or tool output hash. The agent is forbidden from 'updating' the scratchpad in-place; instead, a separate 'Scratchpad Compressor' agent runs every 20 turns to create a true summary that replaces the old scratchpad atomically, preventing incremental drift.

Journey Context:
Agents use scratchpads \(Chain-of-Thought\) to maintain state. In long sessions, the scratchpad becomes a 'palimpsest'—overwritten so many times that it accumulates errors \(the 'Metacognitive Mirage'\). The agent treats the scratchpad as ground truth because it is in its own 'voice', creating a feedback loop where fictional notes corrupt future reasoning. Simple append-only logs fail because they grow too long. The solution is a 'log rotation' model: the agent writes to a 'hot' scratchpad, but a trusted external process \(the Compressor\) periodically archives and condenses it, with the agent verifying the compressed version against source material before accepting it. This separates the 'writing' and 'editing' of memory, preventing the agent from gaslighting itself.
