34-43: Consider documenting TLS/HTTPS requirements for production deployment.The API endpoints table documents HTTP Basic Authentication for cache operations, but there's no mention of TLS/HTTPS. In production environments, HTTP Basic Auth should be transmitted over HTTPS to prevent credential exposure. Consider adding:
- A note that HTTPS/TLS should be configured in production
- Reference to ingress/TLS configuration in the Helm charts
- Security best practices for credential management

15-15: Consider documenting Redis persistence and volatility characteristics.Since Redis is an in-memory store (unlike the previous MinIO persistent storage), build artifacts may be lost on pod restarts or evictions. For a build cache this might be acceptable (cache miss triggers rebuild), but it would help to:
- Explicitly note that Redis storage is volatile by default
- Document whether Redis persistence (RDB snapshots or AOF) is enabled
- Explain the tradeoff between cache durability and rebuild performance

stylelint selector-not-notation rule default simple complex
💡 Result:
The stylelint rule "selector-not-notation" enforces the notation used in :not pseudo-class selectors, with two options: "simple" or "complex". There is no default value; the rule must be explicitly configured with one of these options to be enabled, as no rules are turned on by default in stylelint. "simple" enforces Selectors Level 3 notation (backwards compatible with older browsers), disallowing complex selectors like :not(a, div) or :not(a.foo), but allowing :not(a):not(div) or :not(a). "complex" enforces modern Selectors Level 4 notation, disallowing simple chained notation like :not(a):not(div), but allowing :not(a, div), :not(a.foo), and more complex forms like :not(a).foo:not(:empty). Note that switching notations can change selector specificity, e.g., a:not(.foo,.bar) has specificity 0,1,1 while a:not(.foo):not(.bar) has 0,2,1. The rule is autofixable.

CSS :not() pseudo-class selector complex notation syntax
💡 Result:
The CSS :not pseudo-class uses the syntax :not(<>) where <> is a comma-separated list of one or more selectors. It matches elements that do not match any of the selectors in the list. The argument cannot include pseudo-elements but supports simple, compound, and complex selectors (Selectors Level 4). Examples: - Basic: p:not(.fancy) - selects p elements without class "fancy" - Multiple: p:not(.foo, .bar) - selects p elements without class "foo" or "bar" (equivalent to p:not(.foo):not(.bar)) - Complex: p:not(article *) - selects p elements not descendants of article - With invalid selectors: Use :not(:is(.foo, :invalid)) to avoid invalidating the rule, as direct invalid selectors invalidate the entire :not Key notes: - Specificity is that of the most specific selector in the :not argument. - Invalid selectors in the list invalidate the whole rule (unless wrapped in :is). - Cannot nest :not or use pseudo-elements in argument. - Defined in Selectors Level 4 (updated from Level 3's single simple selector).

stylelint-config-standard-scss default rules enabled selector-not-notation
💡 Result:
Yes, the "selector-not-notation" rule is enabled by default in stylelint-config-standard-scss. It inherits the setting from stylelint-config-standard, where it is explicitly set to "complex" ('selector-not-notation': 'complex'). The stylelint-config-standard-scss config extends stylelint-config-standard without overriding this rule, as confirmed by its index.js file contents, which do not mention "selector-not-notation".

Replace invalid :not() syntax with valid complex notation to satisfy stylelint.
Lines 33 and 38 use chained simple :not() selectors, which violates the configured selector-not-notation: complex rule (inherited from stylelint-config-standard-scss).
The proposed syntax :not(##_) is invalid CSS. The :not() pseudo-class requires comma-separated selectors per CSS Selectors Level 4. Use :not(#) instead, noting this reduces specificity from 0,2,1 to 0,1,1:
