The `letsencrypt-email-prod` and `letsencrypt-email-stag` properties can now be set per app in addition to globally, resolving app-level before the global value for the app's selected `letsencrypt-server`. An app that sets its own email renders a namespaced cert-manager `Issuer` using that email, while apps without an override continue to use the shared `ClusterIssuer` with the global email.
Values supplied through docker options, `--ttl-seconds`, and `-e` flowed into a Bash `eval` during build, deploy, and run, letting a low-privileged user execute arbitrary commands on the host as the dokku user. These arguments are now tokenized and passed through to the container verbatim, without shell expansion. A one-time migration repairs stored labels whose backticks were saved with a stray backslash so Traefik-style rules stay valid on the next deploy.

`network:list` and `network:info` now expose a `DokkuManaged` boolean derived from the `com.dokku.network-name` label that `network:create` applies, and `network:list` gains a `--dokku-managed` flag to restrict output to dokku-created networks. This lets tooling distinguish networks dokku created from Docker built-ins and networks created by other tooling such as compose.
The nginx deploy-time pre-validation runs `nginx -t` against a minimal wrapper that omits the global `load_module` directives, so a custom `nginx.conf.sigil` using a directive from a dynamically loaded module fails validation even though it is valid against the running server. Document overriding the `validate-config` template through the `nginx-app-template-source` trigger as the supported workaround.
Add parallel -list keys to docker-options:report --format json so export
tools can round-trip options without splitting space-joined strings.
Closes#8799
Add buildpacks:set --replace so callers can replace an app's complete ordered buildpack list in one command while preserving existing single-buildpack and --index behavior.
Closes#8802
Align autoscaling-auth:report with annotations and labels reporting so export tools can recover configured trigger auth via flat JSON keys and info flags, while stdout stays secret-safe unless --include-metadata is used.
Closes#8800
Adds a `--format json` flag to `plugin:list` whose output includes each plugin's install source - for git-based third-party plugins, the git remote URL, the checked-out commit, and the followed branch - so the set of installed plugins can be reconstructed elsewhere.
Closes#8798.

- #8796: @josegonzalez Add --format json support to ps:scale
The `ps:scale` command now accepts a `--format` flag that defaults to `stdout` and can be set to `json` to emit the current formation as a JSON array of process type and quantity objects, matching the JSON output the `:report` subcommands already provide. The flag only applies when displaying the current formation; it is ignored when process types are supplied for scaling. When no scale has been set for the app, the JSON output is an empty array.
The `apps:list` command now accepts a `--format` flag that defaults to `stdout` and can be set to `json` to emit the app names as a JSON array, matching the JSON output the `:report` subcommands already provide. When no apps exist, the JSON output is an empty array.

Users can override the default 3-line surrounding context per change. Pass
`--context -1` to render the full resource around every change, matching
upstream `helm diff upgrade` behavior.
Adds a `scheduler-k3s:preview <app>` command that renders a unified diff
between the manifests currently stored in the live Helm release for an app
and the manifests that the next deploy would roll out. The diff is produced
entirely via the Helm Go SDK that scheduler-k3s already uses, with no
external `helm` binary or `helm-diff` plugin install required. The
underlying diff and parse logic is vendored from `databus23/helm-diff`
(Apache 2.0) into a new internal package, trimmed of three-way-merge,
release-ownership tracking, and the non-default output formatters.
The chart-construction half of `TriggerSchedulerDeploy` has been extracted
into a reusable `BuildAppChart` helper so deploy and preview share the
same chart materialization without duplicating template logic. Secret
values are redacted by default in preview output; `--show-secrets` and
`--show-secrets-decoded` flags match the upstream `helm diff` UX. Only the
main app helm release is compared in this iteration; auxiliary releases
for config vars, image-pull secrets, and TLS certificates are out of scope
and documented as such.
Annotation and label values containing a newline previously round-tripped
as two adjacent `key: value` lines, and the second line then failed the
`SplitN(line, ": ", 2)` parse on read. Move the per-`(processType,
resourceType)` files to `PropertyMap*` storage so `\n` in values and `/`
in keys are preserved verbatim. An idempotent `TriggerInstall` migration
walks `--global` and every app, converting any legacy line-formatted file
in place by probing `PropertyMapGet` first and rewriting via
`PropertyListGet` only when the probe fails. Property names are
unchanged, so the annotations/labels report scanner and the
`reservedAnnotationPrefixes` filter keep working without modification.
Closes#8719.
Chart property names containing `/` failed because per-key flat-file storage interpreted the slash as a filesystem path separator, and any move to line-based storage would silently truncate multi-line values. A new `PropertyMap*` helper family in `common` persists each map as a single JSON file so both `/` in keys and `\n` in values round-trip losslessly. Chart overrides move to `chart-overrides.<chart>` and an idempotent `TriggerInstall` migration rewrites any legacy `chart.<chart>.<key>` files into the new layout. The deprecated `scheduler-k3s:set --global chart.*` form is rerouted through the same map storage so it does not silently orphan writes. Closes#8717.
