This will still not fix the lockfile if it's out of date:

[workspace]
channels = ["conda-forge"]
platforms = ["linux-64", "osx-arm64"]

[dependencies]
python = ">=3.14.2,<3.15"

[pypi-dependencies]
svgdigitizer = {git = "https://github.com/echemdb/svgdigitizer.git"}
ec-tools = {git = "https://github.com/echemdb/ec-tools.git", branch = "main"}

Run pixi install, will create a proper lockfile

# Now remove main
ec-tools = {git = "https://github.com/echemdb/ec-tools.git"}

Run pixi install, will not update the lockfile
Run pixi update, will update the lockfile

# Now add main back
ec-tools = {git = "https://github.com/echemdb/ec-tools.git", branch = "main"}

Run pixi install, will not update the lockfile but does find it not satisfiable. This is the issue!
Run pixi update to update, this shouldn't be required

Now it fixes the issue when switching the branch, but there is still some weird behavior when using rev

It always adds the rev for the default branch:

ec-tools = {git = "https://github.com/echemdb/ec-tools.git"}

      - pypi: git+https://github.com/echemdb/ec-tools.git?rev=693f4bef9243d06849cd807e866ed03562d30bb8#693f4bef9243d06849cd807e866ed03562d30bb8

If you change the rev to something else, it will lock that and it will never invalidate:

ec-tools = {git = "https://github.com/echemdb/ec-tools.git", rev = "main"}

pixi install results in:

      - pypi: git+https://github.com/echemdb/ec-tools.git?rev=main#693f4bef9243d06849cd807e866ed03562d30bb8

now removing the rev from the pixi.toml:

ec-tools = {git = "https://github.com/echemdb/ec-tools.git"}

pixi install again the rev=main stays in the lockfile.

      - pypi: git+https://github.com/echemdb/ec-tools.git?rev=main#693f4bef9243d06849cd807e866ed03562d30bb8

Can you please comment and resolve rubens suggestions? :)

tested all use-cases that are mentioned in the PR ( also between rev <-> tag ). Works as expected.
