@wolfv do you understand the failure here?

I looked at the solver differences between mamba and rattler. The two entries look like this:

{
  "key": "vc-14.3-h8a93ad2_22.conda",
  "value": {
    "build": "h8a93ad2_22",
    "build_number": 22,
    "depends": [
      "vc14_runtime >=14.40.33810"
    ],
    "license": "BSD-3-Clause",
    "license_family": "BSD",
    "md5": "a47cd756e88d8a80dfae678842d4acc9",
    "name": "vc",
    "sha256": "b72e7410ec0a748d21e9e997234fc474e3367cee8f509b07eb8182d3584a38d8",
    "size": 17462,
    "subdir": "win-64",
    "timestamp": 1728400826503,
    "track_features": "vc14",
    "version": "14.3"
  }
}
{
  "key": "vc-14.3-ha32ba9b_22.conda",
  "value": {
    "build": "ha32ba9b_22",
    "build_number": 22,
    "depends": [
      "vc14_runtime >=14.38.33135"
    ],
    "license": "BSD-3-Clause",
    "license_family": "BSD",
    "md5": "311c9ba1dfdd2895a8cb08346ff26259",
    "name": "vc",
    "sha256": "2a47c5bd8bec045959afada7063feacd074ad66b170c1ea92dd139b389fcf8fd",
    "size": 17447,
    "subdir": "win-64",
    "timestamp": 1728400826998,
    "track_features": "vc14",
    "version": "14.3"
  }
}

They are very similar, only difference is the lower bound on the dependency.

Rattler selects the one that has the higher timestamp (was built later). I think that's the correct behavior. I am not sure why mamba selects the other one yet.

OK, the problme on the mamba side looks like it's related to dividing the timestamp by 1000:

info     libsolv  Fallback to timestamp comparison: 1728400826 vs 1728400826: [-1]
info     libsolv  Selecting variant [a] of (a) vc-14.3-h8a93ad2_22 vs (b) vc-14.3-ha32ba9b_22 (score: -1)

libsolv sees the two timestamps as equal and thus selects a different solution here.
