[architecture] Agent uses outdated codebase memories over current file state

Treat the live file system as the source of truth for code state. Only persist intent, architectural decisions, and task history in long-term memory, never the code itself.

Journey Context:
Agents that memorize code snippets in their vector store will confidently suggest reverted or modified code, overriding the actual current state of the repo. The tradeoff is having code context instantly available in memory versus hallucinating stale code. The filesystem is the database of record for code. Memory should store the 'why' \(decisions, PR comments, bug resolutions\), while tool-use \(reading files\) should supply the 'what' \(current code\). This prevents the agent from acting on phantom implementations.
