WalkthroughThe Helm chart adds managed application settings through generated ConfigMaps and Deployment mounts. It adds database, instance, and grouped application configuration values. It adds conditional Gateway API HTTPRoute rendering and installation notes. README documentation covers database, application, and OAuth2 identity-provider configuration.

In `@README.md`:
- Line 53: Replace every newly added tilde code fence in README.md with backtick
fences, including the fences near the referenced sections, so the README
complies with the configured MD048 Markdownlint rule.
In `@templates/deployment.yaml`:
- Around line 79-89: The deployment template currently renders duplicate
MEMOS_DSN entries when both database.connectionString and
database.existingSecret are configured. Make these inputs mutually exclusive by
changing the conditional flow around database.connectionString and
database.existingSecret, preferably failing template rendering when both are
nonempty; otherwise use an else-if structure and document the connectionString
precedence in the existing configuration documentation.
In `@templates/httproute.yaml`:
- Around line 24-37: Update the HTTPRoute rules loop to emit a list item
immediately for each entry in .Values.httpRoute.rules. Nest matches, filters,
and backendRefs under that item, while allowing rules without matches to remain
valid and use the default "/" prefix behavior.
In `@templates/NOTES.txt`:
- Around line 2-14: Update the HTTPRoute visit message near APP_HOSTNAME to
avoid hardcoding https://; derive the scheme from a configurable value or print
a scheme-neutral hostname and path. Preserve the existing hostname and rule-path
rendering for both HTTP and HTTPS listener configurations.
In `@templates/settings.yaml`:
- Around line 8-33: Update templates/settings.yaml (lines 8-33) so
credential-bearing settings, especially settings.idps[*].config with
clientSecret, are supplied through Secret-backed settings-file support rather
than serialized into the ConfigMap; retain only non-sensitive settings in the
ConfigMap. Update README.md (lines 101-130) to replace the plaintext
clientSecret example with the Secret-backed configuration flow.

🌐 Web query:
According to the current Kubernetes API documentation, what is the behavior when a container env list contains multiple EnvVar entries with the same name?
💡 Result:
According to the Kubernetes API documentation and established behavior, when a container's environment variable list (env) contains multiple entries with the same name, the values defined in the env list take precedence over values defined in envFrom [1][2][3]. While Kubernetes allows these duplicates to be persisted, they are generally discouraged [4][5]. The behavior associated with duplicate env entries is as follows: 1. Precedence: Values defined explicitly in the env list take precedence over those defined via envFrom [1][2][3]. 2. Patching and Updates: The presence of duplicate names in the env list can cause significant issues with kubectl apply and other patching mechanisms [4][5]. Because the env list uses the name field as a merge key, these tools often treat the key as ambiguous [5]. Consequently, attempting to update or remove one duplicate entry can result in all entries with that name being deleted or cause patch errors [4][5][6][7]. 3. Validation: Historically, Kubernetes has not strictly enforced uniqueness for the name field within the env list at the API level, allowing such configurations to be created and run [7]. However, it is strongly recommended to avoid duplicate names to prevent unexpected application behavior and operational issues with tooling [4][5]. Users are advised to maintain unique names for all environment variables within a container's configuration [4][5].

Make MEMOS_DSN inputs mutually exclusive.
values.yaml and README.md present database.connectionString and database.existingSecret as an either-or choice. If both are set, this template emits two MEMOS_DSN env entries; the connectionString value will take precedence over the secretKeyRef, but Kubernetes still keeps both entries and can make later kubectl apply updates ambiguous. Fail when both are nonempty, or replace the second block with else if so connectionString takes precedence and document that precedence.
