+# Project Memory
+
+Use the Qdrant MCP server as durable, project-scoped memory for non-trivial work.
+
+1. Recall: before planning or editing, call `qdrant-find` with a concise semantic query containing the current goal plus relevant errors, components, or symbols. If Qdrant is unavailable or returns no useful result, continue without blocking the task.
+2. Validate: treat recalled memory as a lead, not as authority. Confirm it against the current repository, configuration, tests, and user request; current evidence wins whenever memory is stale or conflicting.
+3. Persist: after successful verification, call `qdrant-find` once more to avoid duplicates, then use `qdrant-store` only for new durable knowledge such as architectural decisions, project conventions, confirmed fixes, recurring pitfalls, or reliable commands.
+
+- Store one self-contained fact per memory, including enough rationale or evidence to make it useful in a future session.
+- Add compact metadata when useful, such as `type`, `component`, and `source`; do not rely on metadata instead of clear memory text.
+- Do not store transient progress, full conversation summaries, speculative conclusions, raw logs, large code blocks, generated artifacts, secrets, credentials, tokens, or personal data.
+- Do not persist a memory until the relevant change or conclusion has been validated. If a previous memory is wrong, follow current repository evidence and store a clearly labeled correction only when it will prevent recurrence.
+
 # Python Scripting
 
 - Use `uv` for execution, dependencies, environments, and tools: `uv run`, `uv add`, `uv sync`, and `uv tool run`. Preserve another workflow only when the project explicitly standardizes on it.
