gitStream miscategorizes the changes in PR

Description of the problem Lately (about the last month) I noticed a wried behavior with gitStream in our Repo where it is auto-approving PRs.

For example (can't provide link to the PR since it's a private repo): When I opened a PR for a python file client.py (+16 lines added -1 removed = total of 17 lines) the gitStream bot auto-approved the CR. The bot label it as a safe-changes, so i tried to validate the conditions for save_changes automation, but couldn't find any reason to categorize the PR as safe-changes

the condition is: {{ is.safe }}

where:

docs: {{ files | allDocs }}
tests: {{ files | allTests }}
asset: {{ files | match(regex=r/\.(png|svg|gif|css)$/) | every }}
formatting: {{ source.diff.files | isFormattingChange }}
safe: {{ is.docs or is.tests or is.asset or is.formatting }}

Steps to reproduce the behavior:

The .cm automation file:


# -*- mode: yaml -*-
manifest:
version: 1.0

automations: safe_changes: if:

{{ is.safe }} run:
action: approve@v1
action: add-label@v1 args: label: 'safe-changes'

small_changes: if:
{{ is.small_changes }} run:
action: approve@v1
action: add-label@v1 args: label: 'small-changes'

is: docs: {{ files | allDocs }} tests: {{ files | allTests }} asset: {{ files | match(regex=r/.(png|svg|gif|css)$/) | every }} formatting: {{ source.diff.files | isFormattingChange }} safe: {{ is.docs or is.tests or is.asset or is.formatting }}

additions: {{ branch.diff.files_metadata | map(attr='additions') | sum }} deletions: {{ branch.diff.files_metadata | map(attr='deletions') | sum }} small_changes: {{ (is.additions + is.deletions) <= 10 }}


2. The PR URL (as it contains the repo and PR identifiers)
Can't provide as its a private repo, but can be reproduced with any dummy repo with python file

**Expected behavior**

Shouldn't give any label as it's not match the automation conditions
