fix: image overrides produced one malformed helm argument - #124
Conversation
`mapfile` makes each line of image-args.txt a single array element, so writing
`--set versions.ide=latest` as one line handed helm one argument containing a
space:
Error: unknown flag: --set versions.ide
The flag and its value have to be separate elements. Only triggered when an
override was actually passed, which is why every deploy so far missed it.
Also pins helm-diff to v3.9.11. Its current release declares `platformHooks`,
which the pinned helm v3.16.3 cannot parse, so the plugin failed to load and
the preview rendered nothing at all - the diff step tolerates failure, so this
was silent in both deploy and bootstrap.

databus23 helm-diff v3.9.11 platformHooks Helm 3.16.3 compatibility
💡 Result:
The databus23/helm-diff plugin version 3.9.11 is not compatible with Helm 3.16.3 [1][2][3]. Starting with recent versions of helm-diff (specifically those that introduced the use of platformHooks in the plugin.yaml file), the plugin requires Helm 3.18.0 or later to function correctly [1][2]. If you attempt to use helm-diff versions that utilize platformHooks with Helm 3.16.3, you will encounter a failure during plugin loading, typically manifesting as an error similar to: "error unmarshaling JSON: while decoding JSON: json: unknown field platformHooks" [4][3][5]. This occurs because Helm 3.16.x does not recognize or support the platformHooks schema definition used in newer helm-diff plugin.yaml files [1][2][3]. To resolve this incompatibility, you must upgrade your Helm installation to at least version 3.18.0 [1][2][3].

Make helm-diff installation and preview fail closed.
Both workflows ignore plugin installation and helm diff failures. Helm 3.16.3 cannot load helm-diff v3.9.11 because platformHooks is unsupported. The workflow can therefore apply changes without a valid preview. Remove || true from these commands.

Helm official documentation --set comma escaping values comma-separated assignments
💡 Result:
In Helm, the --set flag and related flags (like --set-string) use the comma character as a delimiter to separate multiple key-value assignments [1][2][3]. Consequently, if a value itself contains a comma, Helm will incorrectly interpret it as a separator unless the comma is escaped [4][5]. To include a literal comma in a value assigned via --set, you must escape it using a backslash () [4][6][5]. For example, to set a key named password to the value value1,value2, you should use the following syntax [4][7]: helm install my-release my-chart --set password=value1,value2 It is important to note that when running this command in a shell environment (like Bash or Zsh), you may also need to account for shell quoting rules to ensure the backslash is correctly passed to the Helm CLI [1]. Using single quotes around the entire key=value argument is often the most reliable way to handle this [1]: helm install my-release my-chart --set 'password=value1,value2' Alternative approaches: If escaping becomes complex or if you are dealing with large amounts of data, consider these alternatives to avoid the comma-splitting behavior entirely: 1. Use the -f or --values flag: Write the complex values into a YAML file and provide that file to Helm instead of using --set [8][2][3]. 2. Use --set-file: If the value is long or dynamically generated, you can store the value in a separate file and assign it using --set-file key=path/to/file [1][2][3]. 3. Use --set-literal: Newer versions of Helm provide the --set-literal flag, which can be used to set a literal string value without the same parsing logic applied to --set [2][3].

Validate image overrides at the reusable-workflow boundary.
deploy-dispatch.yml passes tag inputs without validation, and deploy-e2e.yml builds tags from an unvalidated SHA. Only deploy-staging.yml applies the required regex. A comma can create another Helm --set assignment, and a newline can create a stray mapfile argument. Reject non-string, single-line values outside the required regex before writing image-args.txt.
