Currently the legal pages imprint and privacy are rendered from templates which can be overwritten by placing files into ./var folder. There should be another option to specify URLs in the configuration to directly link to external pages. There is a patch @make-footer-links-configurable.patch  with a proposal. Analyse the options and propose a plan, you may take into account the patch.

claude claude-code-guide Explore general-purpose Plan statusline-setup

- claude: Catch-all for any task that doesn't fit a more specific agent. FleetView's default when no agent name is typed. (Tools: *)

- claude-code-guide: Use this agent when the user asks questions ("Can Claude...", "Does Claude...", "How do I...") about: (1) Claude Code (the CLI tool) - features, hooks, slash commands, MCP servers, settings, IDE integrations, keyboard shortcuts; (2) Claude Agent SDK - building custom agents; (3) Claude API (formerly Anthropic API) - API usage, tool use, Anthropic SDK usage. **IMPORTANT:** Before spawning a new agent, check if there is already a running or recently completed claude-code-guide agent that you can continue via SendMessage. (Tools: Bash, Read, WebFetch, WebSearch)

- Explore: Read-only search agent for broad fan-out searches — when answering means sweeping many files, directories, or naming conventions and you only need the conclusion, not the file dumps. It reads excerpts rather than whole files, so it locates code; it doesn't review or audit it. Specify search breadth: "medium" for moderate exploration, "very thorough" for multiple locations and naming conventions. (Tools: All tools except Agent, ExitPlanMode, Edit, Write, NotebookEdit)

- general-purpose: General-purpose agent for researching complex questions, searching for code, and executing multi-step tasks. When you are searching for a keyword or file and are not confident that you will find the right match in the first few tries use this agent to perform the search for you. (Tools: *)

- Plan: Software architect agent for designing implementation plans. Use this when you need to plan the implementation strategy for a task. Returns step-by-step plans, identifies critical files, and considers architectural trade-offs. (Tools: All tools except Agent, ExitPlanMode, Edit, Write, NotebookEdit)

- statusline-setup: Use this agent to configure the user's Claude Code status line setting. (Tools: Read, Edit)


- deep-research: Deep research harness — fan-out web searches, fetch sources, adversarially verify claims, synthesize a cited report. - When the user wants a deep, multi-source, fact-checked research report on any topic. BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., "what car to buy" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope. Then pass the refined question as args, weaving the answers in.
- frontend-design:frontend-design: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.
- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- verify: Verify that a code change actually does what it's supposed to by running the app and observing behavior. Use when asked to verify a PR, confirm a fix works, test a change manually, check that a feature works, or validate local changes before pushing.
- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.
- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled cloud agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring cloud agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.
TRIGGER — read BEFORE opening the target file; don't skip because it "looks like a one-liner" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).
SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).
- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).
- init: Initialize a new CLAUDE.md file with codebase documentation
- review: Review a pull request
- security-review: Complete a security review of the pending changes on the current branch

Make legal footer links configurable via URLs


I'll explore the current implementation of the legal pages and footer rendering before designing a plan.


Agent

Explore legal pages rendering

Prompt:
I'm investigating how the "imprint" and "privacy" legal pages are served and rendered in this Go + Svelte project (cc-backend, ClusterCockpit).

Please find and report on (medium thoroughness):

1. How the `/imprint` and `/privacy` routes are registered and handled. Search in `web/`, `internal/api/`, `internal/routerConfig/`, or wherever HTTP routes are set up. Show the handler code.

2. How the templates `imprint.tmpl` and `privacy.tmpl` (or similar) are defined and where they live (`web/templates/`). Show how they can be overridden by placing files in the `./var` folder — find the override mechanism (probably in `web/web.go` or template loading code).

3. The `web/templates/base.tmpl` footer block (already partially shown in a patch) — show the surrounding template and how the footer is included.

4. The `web/web.go` file: the `Page` struct, `RenderTemplate` function, and how templates are loaded/parsed (embed.FS vs filesystem override).

5. How `config.Keys` / `ProgramConfig` is structured in `internal/config/config.go` — show the `ProgramConfig` struct and the `Init` function and default `Keys`.

Report exact file paths and line numbers, and include relevant code snippets.


Explore config schema and footer frontend

Prompt:
I'm investigating configuration handling and the footer in cc-backend (Go + Svelte, ClusterCockpit).

Please find and report (medium thoroughness):

1. The config JSON schema validation: `internal/config/schema.go` — show the `configSchema` string structure for the `main`/program config section, especially where "systemd-unit", "resampling", and "api-subjects" properties are defined. I want to know exactly where a new "footer-links" property would be inserted.

2. Where is `config.Keys` (the ProgramConfig) initialized/validated against the schema? Find the `Init` function in `internal/config/config.go` and any schema validation calls.

3. Is there a Svelte frontend footer too, or is the footer ONLY in `web/templates/base.tmpl`? Search `web/frontend/src/` for any footer component, "imprint", "privacy", or "Imprint"/"Privacy Policy" strings. Report what you find.

4. Search the whole repo for the strings "imprint" and "privacy" (case-insensitive) and report every location (file path + line) so I understand all places these are referenced — routes, templates, frontend, docs, config samples.

5. Show the `configs/config.json` main section so I understand current structure.

Report exact file paths, line numbers, and code snippets.

Perfect! Now I have all the information. Let me create a comprehensive report:

## Configuration Handling & Footer Investigation Report

### 1. JSON Schema Configuration (`internal/config/schema.go`)

**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/schema.go` (lines 8-220)

The `configSchema` defines the main program config section. Key properties relevant to your question:

- **`systemd-unit`** (line 87-90): String property for systemd unit name for log viewer
- **`resampling`** (line 91-112): Object with nested properties (minimum-points, trigger, resolutions)
- **`api-subjects`** (line 113-135): Object with nested properties (subject-job-event, subject-node-state, job-concurrency, node-concurrency)

**For inserting a new `footer-links` property**, you would add it to the top-level properties object (between line 12-219, around lines 135-189 where other config objects are defined would be logical). The structure would be after `api-subjects` (line 135) and before `nodestate-retention` (line 136), or you could append it before the closing brace of `db-config` (line 217-219).

Recommended insertion point: **After line 135** (end of api-subjects object), before `nodestate-retention` definition at line 136.

---

### 2. Config Initialization & Validation

**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/config.go`

- **`Keys` initialization** (line 141-148): Global `ProgramConfig` variable with defaults
- **`Init()` function** (line 150-161):
  - Line 151: Calls `Validate(configSchema, mainConfig)` — validates the raw JSON against the schema
  - Lines 152-156: Decodes JSON into the `Keys` struct with `DisallowUnknownFields()`
  - Lines 158-160: Handles resampling configuration initialization

**Validation call location:**
- **`/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/validate.go`** (line 15-29): The `Validate()` function uses `jsonschema` library to compile and validate the schema.

---

### 3. Frontend Footer Investigation

**Result:** There is **NO Svelte frontend footer component**. The footer is **ONLY** in the Go template system.

**Search results for Svelte frontend:**
- No footer component files found in `/web/frontend/src/`
- No references to "imprint", "privacy", "Imprint", or "Privacy Policy" in Svelte code

**Footer location:** **ONLY in `/Users/jan/prg/ClusterCockpit/cc-backend/web/templates/base.tmpl`** (lines 52-64)

---

### 4. Complete "imprint" and "privacy" References in Repository

| File | Line(s) | Content |
|------|---------|---------|
| `/cmd/cc-backend/server.go` | 201-203 | Route handler for `/imprint` → renders `imprint.tmpl` |
| `/cmd/cc-backend/server.go` | 205-207 | Route handler for `/privacy` → renders `privacy.tmpl` |
| `/web/templates/base.tmpl` | 55 | Footer link: `<a href="/imprint" ... >Imprint</a>` |
| `/web/templates/base.tmpl` | 56 | Footer link: `<a href="/privacy" ... >Privacy Policy</a>` |
| `/web/templates/imprint.tmpl` | 1+ | Page template with `<h1>Imprint</h1>` |
| `/web/templates/privacy.tmpl` | 1+ | Page template with `<h1>Privacy</h1>` |
| `/web/web.go` | 225-228 | Allows override: checks for `./var/imprint.tmpl` |
| `/web/web.go` | 232-235 | Allows override: checks for `./var/privacy.tmpl` |
| `/init/README.md` | (doc) | Instructions to copy `imprint.tmpl` and `privacy.tmpl` to `/opt/monitoring/cc-backend/var/` |

---

### 5. Current config.json Structure (main section)

**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/configs/config.json` (lines 2-25)

```json
{
  "main": {
    "addr": "0.0.0.0:443",
    "https-cert-file": "/etc/letsencrypt/live/url/fullchain.pem",
    "https-key-file": "/etc/letsencrypt/live/url/privkey.pem",
    "user": "clustercockpit",
    "group": "clustercockpit",
    "api-allowed-ips": ["*"],
    "short-running-jobs-duration": 300,
    "enable-job-taggers": true,
    "nodestate-retention": {

    },
    "resampling": {
      "minimum-points": 600,

    },

      "subject-job-event": "cc.job.event",
      "subject-node-state": "cc.node.state"
    }
  }
}
```

---

### Key Findings Summary

1. **Schema location:** `/internal/config/schema.go` lines 8-220. Insertion point for new properties: after line 135.
2. **Validation flow:** `Init()` calls `Validate()` which compiles the schema and validates JSON before decoding to `ProgramConfig` struct.
3. **Footer is Go-only:** No Svelte components; footer rendered by `base.tmpl` with hardcoded Imprint/Privacy links.
4. **Routes:** Go handlers at lines 201-207 of `server.go` render `imprint.tmpl` and `privacy.tmpl`.
5. **Override capability:** Both templates can be overridden by placing files in `./var/` directory (checked in `web/web.go` lines 225-235).

Perfect! Now I have all the information I need. Let me compile a comprehensive report with all the findings.

## Summary

I've thoroughly investigated how the `/imprint` and `/privacy` legal pages are served and rendered in the ClusterCockpit Go + Svelte project. Here are my findings:

---

## 1. Route Registration and Handlers

**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/server.go` (lines 201-208)

```go
s.router.HandleFunc("/imprint", func(rw http.ResponseWriter, r *http.Request) {
    rw.Header().Add("Content-Type", "text/html; charset=utf-8")
    web.RenderTemplate(rw, "imprint.tmpl", &web.Page{Title: "Imprint", Build: buildInfo})
})
s.router.HandleFunc("/privacy", func(rw http.ResponseWriter, r *http.Request) {
    rw.Header().Add("Content-Type", "text/html; charset=utf-8")
    web.RenderTemplate(rw, "privacy.tmpl", &web.Page{Title: "Privacy", Build: buildInfo})
})
```

Both routes are registered directly in the `server.go` setup function (not in the generic route configuration). They are simple handlers that:
- Set HTML content-type header
- Call `web.RenderTemplate()` with the appropriate template file
- Pass a minimal `Page` struct with only `Title` and `Build` info (no user info required for these public pages)

---

## 2. Template Files and Override Mechanism

**Template Files:**
- `/Users/jan/prg/ClusterCockpit/cc-backend/web/templates/imprint.tmpl`
- `/Users/jan/prg/ClusterCockpit/cc-backend/web/templates/privacy.tmpl`

**Override Mechanism in `web/web.go` (lines 225-238):**

```go
if path == "templates/imprint.tmpl" {
    if util.CheckFileExists("./var/imprint.tmpl") {
        cclog.Info("overwrite imprint.tmpl with local file")
        templates[strings.TrimPrefix(path, "templates/")] = template.Must(template.Must(base.Clone()).ParseFiles("./var/imprint.tmpl"))
        return nil
    }
}
if path == "templates/privacy.tmpl" {
    if util.CheckFileExists("./var/privacy.tmpl") {
        cclog.Info("overwrite privacy.tmpl with local file")
        templates[strings.TrimPrefix(path, "templates/")] = template.Must(template.Must(base.Clone()).ParseFiles("./var/privacy.tmpl"))
        return nil
    }
}
```

**How it works:**
1. During template initialization (in the `init()` function), the code checks if custom files exist in `./var/`
2. If `./var/imprint.tmpl` or `./var/privacy.tmpl` exist, they are loaded and used instead of the embedded versions
3. The override is done via `ParseFiles()` which parses the local file, while still inheriting the `base.tmpl` layout via `base.Clone()`
4. The same mechanism also applies to `login.tmpl` (lines 218-224)

## 3. Base Template and Footer Block

**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/web/templates/base.tmpl` (lines 52-64)

```html
{{block "footer" .}}
    <footer class="site-footer bg-light">
        <ul class="footer-list">
            <li class="footer-list-item"><a class="link-secondary fs-5" href="/imprint" title="Imprint" rel="nofollow">Imprint</a></li>
            <li class="footer-list-item"><a class="link-secondary fs-5" href="/privacy" title="Privacy Policy" rel="nofollow">Privacy Policy</a></li>
        </ul>
        <ul class="build-list">
        <li class="build-list-item">Version {{ .Build.Version }}</li>
        <li class="build-list-item">Hash {{ .Build.Hash }}</li>
        <li class="build-list-item">Built {{ .Build.Buildtime }}</li>
        </ul>
    </footer>
{{end}}
```

**Surrounding Context (lines 39-50):**

The footer is part of a larger structure where the page checks if it's a PUBLIC display type:

```html
{{else}}
    {{block "navigation" .}}
        <header id="svelte-header"></header>
    {{end}}

    <main class="site-content">
        <div class="container">
            {{block "content" .}}
                Whoops, you should not see this... [MAIN]
            {{end}}
        </div>
    </main>

    {{block "footer" .}}
        <!-- Footer with links to /imprint and /privacy -->
    {{end}}
```

The footer is only included when NOT in PUBLIC mode (line 26 checks `displayType != "PUBLIC"`).

## 4. `web/web.go` - Page Struct, RenderTemplate Function, Template Loading

**Page Struct (lines 255-269):**

```go
type Page struct {
    Title         string                 // Page title
    MsgType       string                 // For generic use in message boxes
    Message       string                 // For generic use in message boxes
    User          schema.User            // Information about the currently logged in user (Full User Info)
    Roles         map[string]schema.Role // Available roles for frontend render checks
    Build         Build                  // Latest information about the application
    Clusters      []string               // List of all cluster names
    SubClusters   map[string][]string    // Map per cluster of all subClusters for use in the Header
    FilterPresets map[string]any         // For pages with the Filter component, this can be used to set initial filters.
    Infos         map[string]any         // For generic use (e.g. username for /monitoring/user/<id>, job id for /monitoring/job/<id>)
    Config        map[string]any         // UI settings for the currently logged in user (e.g. line width, ...)
    Resampling    *config.ResampleConfig // If not nil, defines resampling trigger and resolutions
    Redirect      string                 // The originally requested URL, for intermediate login handling
}
```

**RenderTemplate Function (lines 271-296):**

```go
func RenderTemplate(rw http.ResponseWriter, file string, page *Page) {
    t, ok := templates[file]
    if !ok {
        cclog.Errorf("WEB/WEB > template '%s' not found", file)
    }

    if page.Clusters == nil {
        page.Clusters = make([]string, 0)
    }

    if page.SubClusters == nil {
        page.SubClusters = make(map[string][]string)
        for _, cluster := range archive.Clusters {
            page.Clusters = append(page.Clusters, cluster.Name)

            for _, sc := range cluster.SubClusters {
                page.SubClusters[cluster.Name] = append(page.SubClusters[cluster.Name], sc.Name)
            }
        }
    }

    cclog.Debugf("Page config : %v\n", page.Config)
    if err := t.Execute(rw, page); err != nil {
        cclog.Errorf("Template error: %s", err.Error())
    }
}
```

**Template Loading - Embed FS with Override (lines 199-247):**

```go
//go:embed templates/*
var templateFiles embed.FS

var templates map[string]*template.Template = map[string]*template.Template{}

func init() {
    base := template.Must(template.ParseFS(templateFiles, "templates/base.tmpl"))
    if err := fs.WalkDir(templateFiles, "templates", func(path string, d fs.DirEntry, err error) error {
        if err != nil {
            return err
        }
        if d.IsDir() || path == "templates/base.tmpl" {
            return nil
        }

        if path == "templates/404.tmpl" {
            templates[strings.TrimPrefix(path, "templates/")] = template.Must(template.ParseFS(templateFiles, path))
            return nil
        }
        if path == "templates/login.tmpl" {
            if util.CheckFileExists("./var/login.tmpl") {
                cclog.Info("overwrite login.tmpl with local file")
                templates[strings.TrimPrefix(path, "templates/")] = template.Must(template.Must(base.Clone()).ParseFiles("./var/login.tmpl"))
                return nil
            }
        }
        if path == "templates/imprint.tmpl" {
            if util.CheckFileExists("./var/imprint.tmpl") {
                cclog.Info("overwrite imprint.tmpl with local file")
                templates[strings.TrimPrefix(path, "templates/")] = template.Must(template.Must(base.Clone()).ParseFiles("./var/imprint.tmpl"))
                return nil
            }
        }
        if path == "templates/privacy.tmpl" {
            if util.CheckFileExists("./var/privacy.tmpl") {
                cclog.Info("overwrite privacy.tmpl with local file")
                templates[strings.TrimPrefix(path, "templates/")] = template.Must(template.Must(base.Clone()).ParseFiles("./var/privacy.tmpl"))
                return nil
            }
        }

        templates[strings.TrimPrefix(path, "templates/")] = template.Must(template.Must(base.Clone()).ParseFS(templateFiles, path))
        return nil
    }); err != nil {
        cclog.Abortf("Web init(): Could not find frontend template files.\nError: %s\n", err.Error())
    }

    _ = base
}
```

**Key Points:**
- Templates are embedded via `//go:embed templates/*`
- During init, `base.tmpl` is parsed once and cloned for each page template
- For `imprint.tmpl`, `privacy.tmpl`, and `login.tmpl`, the init function checks for local overrides in `./var/`
- If override files exist, they are parsed with `ParseFiles()` and combined with the cloned base template
- This allows customization without recompiling the binary

## 5. ProgramConfig Structure and Initialization

**File:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/config/config.go`

**ProgramConfig Struct (lines 18-83):**

## Key Observations

1. **No authentication required:** The `/imprint` and `/privacy` routes don't require authentication and pass minimal `Page` data (only `Title` and `Build` info)

2. **Template inheritance:** Both templates inherit from `base.tmpl` through `base.Clone()`, which provides the overall HTML structure including the navigation and footer

3. **Override mechanism is clever:** By checking for files in `./var/` before returning from the `init()` walk, the system allows runtime customization without recompilation

4. **Each legal page defines its own "navigation" and "content" blocks:** Both `imprint.tmpl` and `privacy.tmpl` define these blocks, which are rendered by the base template

5. **Footer links are hardcoded:** The footer in `base.tmpl` has static links to `/imprint` and `/privacy` and will be shown on all pages except those with `displayType == "PUBLIC"`

Prompt:
I'm investigating how the "imprint" and "privacy" legal pages are served and rendered in this Go + Svelte project (cc-backend, ClusterCockpit).

Please find and report on (medium thoroughness):

1. How the `/imprint` and `/privacy` routes are registered and handled. Search in `web/`, `internal/api/`, `internal/routerConfig/`, or wherever HTTP routes are set up. Show the handler code.

2. How the templates `imprint.tmpl` and `privacy.tmpl` (or similar) are defined and where they live (`web/templates/`). Show how they can be overridden by placing files in the `./var` folder — find the override mechanism (probably in `web/web.go` or template loading code).

3. The `web/templates/base.tmpl` footer block (already partially shown in a patch) — show the surrounding template and how the footer is included.

4. The `web/web.go` file: the `Page` struct, `RenderTemplate` function, and how templates are loaded/parsed (embed.FS vs filesystem override).

5. How `config.Keys` / `ProgramConfig` is structured in `internal/config/config.go` — show the `ProgramConfig` struct and the `Init` function and default `Keys`.

Report exact file paths and line numbers, and include relevant code snippets.


I now have a clear picture. The patch is well-targeted. Let me clarify two product decisions before finalizing the plan.


AskUserQuestion

Question: When a footer link is configured as empty (operator wants no imprint/privacy at all), what should happen?

Choices:
Empty/missing → use built-in /imprint and /privacy template pages (the patch's behavior). Link always shown. Fully backward compatible.
Empty string → omit that footer entry entirely, allowing operators to disable a legal page. Missing/unset still falls back to the internal route.

Question: For external imprint/privacy URLs (e.g. https://corp.example/legal), how should links open?

Choices:
Detect http(s):// targets and add target="_blank" rel="noopener"; internal /imprint paths stay same-tab. Best UX.
Keep current behavior — all links open in the same tab regardless of being internal or external (matches the patch exactly).


Your questions have been answered: "When a footer link is configured as empty (operator wants no imprint/privacy at all), what should happen?"="Fall back to internal route", "For external imprint/privacy URLs (e.g. https://corp.example/legal), how should links open?"="New tab if external". You can now continue with these answers in mind.

Both decisions are clear. Empty/missing → internal route fallback; external `http(s)://` targets open in a new tab. The "new tab if external" choice means I can't pass raw strings to the template — I'll precompute an `External` flag in Go (cleaner than registering template funcs).

Let me write the plan.

# Make Footer Legal Links (Imprint / Privacy) Configurable

## Context

Today the footer links to `/imprint` and `/privacy` are **hardcoded** in
`web/templates/base.tmpl`. Operators can customize the *content* of those pages
by dropping `./var/imprint.tmpl` / `./var/privacy.tmpl` (override mechanism in
`web/web.go`), but they cannot point the footer at an **external** legal page
(e.g. a corporate `https://corp.example/legal`) without writing a template that
redirects.

This change adds a config option (`main.footer-links`) so the footer targets can
be set to either the built-in internal routes (default, backward compatible) or
arbitrary external URLs. External URLs open in a new tab; internal paths stay
same-tab. The existing `/imprint`, `/privacy` routes and the `./var/*.tmpl`
override remain unchanged, so nothing breaks for current deployments.

The user-provided `make-footer-links-configurable.patch` is the basis for this
plan, with two refinements agreed with the user:
1. An **empty** configured value falls back to the internal route (link always shown).
2. **External** (`http://` / `https://`) targets render with `target="_blank" rel="noopener noreferrer"`.

## Approach

### 1. Config struct + defaults — `internal/config/config.go`
- Add `FooterLinks FooterLinksConfig \`json:"footer-links"\`` to `ProgramConfig`
  (struct around line 18-83).
- Add the new type:
  ```go
  // FooterLinksConfig configures the legal/footer links rendered in the UI.
  type FooterLinksConfig struct {
      Imprint string `json:"imprint"` // Target URL/path for the "Imprint" footer entry.
      Privacy string `json:"privacy"` // Target URL/path for the "Privacy Policy" footer entry.
  }
  ```
- Add defaults to the `Keys` literal (lines 141-148):
  ```go
  FooterLinks: FooterLinksConfig{Imprint: "/imprint", Privacy: "/privacy"},
  ```
  (Handles the "key absent entirely" case; the web-layer fallback below handles
  the "key present but value empty" case.)

### 2. JSON schema — `internal/config/schema.go`
- Insert a `footer-links` object property into `configSchema` (logical spot:
  after the `api-subjects` block, ~line 135, before `nodestate-retention`):
  ```json
  "footer-links": {
    "description": "Optional footer links for legal pages (imprint/privacy). Internal path or external URL.",
    "type": "object",
    "properties": {
      "imprint": { "description": "Target URL/path for the footer imprint link.", "type": "string" },
      "privacy": { "description": "Target URL/path for the footer privacy link.", "type": "string" }
    }
  }
  ```
  Decoding uses `DisallowUnknownFields()`, so the schema/struct must stay in sync.

### 3. Render layer — `web/web.go`
The patch passed `config.FooterLinksConfig` straight to the template, but the
"new tab if external" rule needs a precomputed boolean (the templates register no
custom funcs, so `strings.HasPrefix` isn't available in-template). Add a small
render type instead:
- Keep the default-link constants:
  ```go
  const (
      defaultImprintLink = "/imprint"
      defaultPrivacyLink = "/privacy"
  )
  ```
- Add render types:
  ```go
  type FooterLink struct {
      URL      string // resolved target (internal path or external URL)
      External bool   // true => open in new tab
  }
  type FooterLinks struct {
      Imprint FooterLink
      Privacy FooterLink
  }
  ```
- Add `FooterLinks FooterLinks` field to the `Page` struct (lines 255-269).
- Add a helper:
  ```go
  func resolveFooterLink(v, def string) FooterLink {
      if v == "" {
          v = def
      }
      ext := strings.HasPrefix(v, "http://") || strings.HasPrefix(v, "https://")
      return FooterLink{URL: v, External: ext}
  }
  ```
  (`strings` is already imported in `web.go`.)
- In `RenderTemplate` (after the existing nil-guards, ~line 289), set:
  ```go
  page.FooterLinks = FooterLinks{
      Imprint: resolveFooterLink(config.Keys.FooterLinks.Imprint, defaultImprintLink),
      Privacy: resolveFooterLink(config.Keys.FooterLinks.Privacy, defaultPrivacyLink),
  }
  ```
  Setting it for every page (incl. the minimal `Page` used by the `/imprint` and
  `/privacy` handlers in `cmd/cc-backend/server.go:201-208`) means the footer
  renders correctly everywhere — no handler changes needed.

### 4. Template — `web/templates/base.tmpl` (footer block, lines 52-64)
Replace the two hardcoded `<li>` entries with config-driven ones that switch
`target`/`rel` on the `External` flag:
```html
<li class="footer-list-item"><a class="link-secondary fs-5" href="{{ .FooterLinks.Imprint.URL }}" title="Imprint"{{ if .FooterLinks.Imprint.External }} target="_blank" rel="noopener noreferrer"{{ else }} rel="nofollow"{{ end }}>Imprint</a></li>
<li class="footer-list-item"><a class="link-secondary fs-5" href="{{ .FooterLinks.Privacy.URL }}" title="Privacy Policy"{{ if .FooterLinks.Privacy.External }} target="_blank" rel="noopener noreferrer"{{ else }} rel="nofollow"{{ end }}>Privacy Policy</a></li>
```

### 5. Sample config — `configs/config.json`
Add to the `main` block (matches the patch):
```json
"footer-links": {
  "imprint": "/imprint",
  "privacy": "/privacy"
},
```

## Notes / Decisions
- **Frontend (Svelte):** not involved — the footer lives only in the Go template
  `base.tmpl`; there is no Svelte footer component.
- **Backward compatible:** unset config → defaults to internal routes; the
  `/imprint`, `/privacy` handlers and `./var/*.tmpl` override are untouched.
- **Empty value behavior:** empty string falls back to the internal route (link
  always shown) — per user choice. (Hiding a link entirely is intentionally not
  supported.)
- Differs from the patch only in: the render-time `FooterLink{URL, External}`
  type instead of passing `config.FooterLinksConfig` directly, and the new-tab
  template logic.

## Files to change
- `internal/config/config.go` — struct, type, defaults
- `internal/config/schema.go` — schema property
- `web/web.go` — render types, `Page` field, helper, `RenderTemplate`
- `web/templates/base.tmpl` — footer links
- `configs/config.json` — sample

## Verification
1. `go build ./...` — compiles.
2. `go vet ./internal/config/... ./web/...`.
3. Run with **no** `footer-links` set:
   `./cc-backend -server -dev` → footer shows Imprint/Privacy pointing to
   `/imprint`, `/privacy` (same tab), pages render as before.
4. Set `main.footer-links` to external URLs in `config.json`, e.g.
   `{"imprint":"https://example.com/legal","privacy":"/privacy"}`, restart,
   load any page, and inspect footer HTML: the external Imprint link has
   `target="_blank" rel="noopener noreferrer"`; the internal Privacy link keeps
   `rel="nofollow"` and no `target`.
5. Set an **empty** value (`"imprint":""`) → confirm it falls back to `/imprint`.
6. Set an invalid type (e.g. `"imprint": 5`) → confirm schema validation rejects
   the config at startup.

  "footer-links": {
    "description": "Optional footer links for legal pages (imprint/privacy). Internal path or external URL.",
    "type": "object",
    "properties": {
      "imprint": { "description": "Target URL/path for the footer imprint link.", "type": "string" },
      "privacy": { "description": "Target URL/path for the footer privacy link.", "type": "string" }
    }
  }
  ```
  Decoding uses `DisallowUnknownFields()`, so the schema/struct must stay in sync.

### 3. Render layer — `web/web.go`
The patch passed `config.FooterLinksConfig` straight to the template, but the
"new tab if external" rule needs a precomputed boolean (the templates register no
custom funcs, so `strings.HasPrefix` isn't available in-template). Add a small
render type instead:
- Keep the default-link constants:
  ```go
  const (
      defaultImprintLink = "/imprint"
      defaultPrivacyLink = "/privacy"
  )
  ```
- Add render types:
  ```go
  type FooterLink struct {
      URL      string // resolved target (internal path or external URL)
      External bool   // true => open in new tab
  }
  type FooterLinks struct {
      Imprint FooterLink
      Privacy FooterLink
  }
  ```
- Add `FooterLinks FooterLinks` field to the `Page` struct (lines 255-269).
- Add a helper:
  ```go
  func resolveFooterLink(v, def string) FooterLink {
      if v == "" {
          v = def
      }
      ext := strings.HasPrefix(v, "http://") || strings.HasPrefix(v, "https://")
      return FooterLink{URL: v, External: ext}
  }
  ```
  (`strings` is already imported in `web.go`.)
- In `RenderTemplate` (after the existing nil-guards, ~line 289), set:
  ```go
  page.FooterLinks = FooterLinks{
      Imprint: resolveFooterLink(config.Keys.FooterLinks.Imprint, defaultImprintLink),
      Privacy: resolveFooterLink(config.Keys.FooterLinks.Privacy, defaultPrivacyLink),
  }
  ```
  Setting it for every page (incl. the minimal `Page` used by the `/imprint` and
  `/privacy` handlers in `cmd/cc-backend/server.go:201-208`) means the footer
  renders correctly everywhere — no handler changes needed.

### 4. Template — `web/templates/base.tmpl` (footer block, lines 52-64)
Replace the two hardcoded `<li>` entries with config-driven ones that switch
`target`/`rel` on the `External` flag:
```html
<li class="footer-list-item"><a class="link-secondary fs-5" href="{{ .FooterLinks.Imprint.URL }}" title="Imprint"{{ if .FooterLinks.Imprint.External }} target="_blank" rel="noopener noreferrer"{{ else }} rel="nofollow"{{ end }}>Imprint</a></li>
<li class="footer-list-item"><a class="link-secondary fs-5" href="{{ .FooterLinks.Privacy.URL }}" title="Privacy Policy"{{ if .FooterLinks.Privacy.External }} target="_blank" rel="noopener noreferrer"{{ else }} rel="nofollow"{{ end }}>Privacy Policy</a></li>
```

### 5. Sample config — `configs/config.json`
Add to the `main` block (matches the patch):
```json
"footer-links": {
  "imprint": "/imprint",
  "privacy": "/privacy"
},
```

## Notes / Decisions
- **Frontend (Svelte):** not involved — the footer lives only in the Go template
  `base.tmpl`; there is no Svelte footer component.
- **Backward compatible:** unset config → defaults to internal routes; the
  `/imprint`, `/privacy` handlers and `./var/*.tmpl` override are untouched.
- **Empty value behavior:** empty string falls back to the internal route (link
  always shown) — per user choice. (Hiding a link entirely is intentionally not
  supported.)
- Differs from the patch only in: the render-time `FooterLink{URL, External}`
  type instead of passing `config.FooterLinksConfig` directly, and the new-tab
  template logic.

## Files to change
- `internal/config/config.go` — struct, type, defaults
- `internal/config/schema.go` — schema property
- `web/web.go` — render types, `Page` field, helper, `RenderTemplate`
- `web/templates/base.tmpl` — footer links
- `configs/config.json` — sample

## Verification
1. `go build ./...` — compiles.
2. `go vet ./internal/config/... ./web/...`.
3. Run with **no** `footer-links` set:
   `./cc-backend -server -dev` → footer shows Imprint/Privacy pointing to
   `/imprint`, `/privacy` (same tab), pages render as before.
4. Set `main.footer-links` to external URLs in `config.json`, e.g.
   `{"imprint":"https://example.com/legal","privacy":"/privacy"}`, restart,
   load any page, and inspect footer HTML: the external Imprint link has
   `target="_blank" rel="noopener noreferrer"`; the internal Privacy link keeps
   `rel="nofollow"` and no `target`.
5. Set an **empty** value (`"imprint":""`) → confirm it falls back to `/imprint`.
6. Set an invalid type (e.g. `"imprint": 5`) → confirm schema validation rejects
   the config at startup.

Question: select:ExitPlanMode


I've finished the plan. Here's a summary of what I found and recommend.

## Findings
- The footer lives **only** in `web/templates/base.tmpl` (no Svelte footer component). Links to `/imprint` and `/privacy` are hardcoded.
- The internal routes are registered in `cmd/cc-backend/server.go:201-208`, rendering `imprint.tmpl` / `privacy.tmpl`, which operators can already override via `./var/*.tmpl` (mechanism in `web/web.go`).
- Config flows through `internal/config/config.go` (`ProgramConfig`/`Keys`) and is validated against the JSON schema in `internal/config/schema.go` with `DisallowUnknownFields()`, so struct and schema must stay in sync.

## Recommendation
Adopt the patch with two refinements you confirmed:
1. Add `main.footer-links` (`imprint`/`privacy`) to config + schema + defaults; empty/missing falls back to the internal routes — fully backward compatible.
2. Instead of passing the raw config strings to the template (the patch's approach), precompute a `FooterLink{URL, External}` in `RenderTemplate`, so external `http(s)://` targets render `target="_blank" rel="noopener noreferrer"` while internal paths stay same-tab. This avoids registering template funcs.

Touches 5 files: `internal/config/config.go`, `internal/config/schema.go`, `web/web.go`, `web/templates/base.tmpl`, `configs/config.json`.

# Make Footer Legal Links (Imprint / Privacy) Configurable

## Context

Today the footer links to `/imprint` and `/privacy` are **hardcoded** in
`web/templates/base.tmpl`. Operators can customize the *content* of those pages
by dropping `./var/imprint.tmpl` / `./var/privacy.tmpl` (override mechanism in
`web/web.go`), but they cannot point the footer at an **external** legal page
(e.g. a corporate `https://corp.example/legal`) without writing a template that
redirects.

This change adds a config option (`main.footer-links`) so the footer targets can
be set to either the built-in internal routes (default, backward compatible) or
arbitrary external URLs. External URLs open in a new tab; internal paths stay
same-tab. The existing `/imprint`, `/privacy` routes and the `./var/*.tmpl`
override remain unchanged, so nothing breaks for current deployments.

The user-provided `make-footer-links-configurable.patch` is the basis for this
plan, with two refinements agreed with the user:
1. An **empty** configured value falls back to the internal route (link always shown).
2. **External** (`http://` / `https://`) targets render with `target="_blank" rel="noopener noreferrer"`.

## Approach

### 1. Config struct + defaults — `internal/config/config.go`
- Add `FooterLinks FooterLinksConfig \`json:"footer-links"\`` to `ProgramConfig`
  (struct around line 18-83).
- Add the new type:
  ```go
  // FooterLinksConfig configures the legal/footer links rendered in the UI.
  type FooterLinksConfig struct {
      Imprint string `json:"imprint"` // Target URL/path for the "Imprint" footer entry.
      Privacy string `json:"privacy"` // Target URL/path for the "Privacy Policy" footer entry.
  }
  ```
- Add defaults to the `Keys` literal (lines 141-148):
  ```go
  FooterLinks: FooterLinksConfig{Imprint: "/imprint", Privacy: "/privacy"},
  ```
  (Handles the "key absent entirely" case; the web-layer fallback below handles
  the "key present but value empty" case.)

### 2. JSON schema — `internal/config/schema.go`
- Insert a `footer-links` object property into `configSchema` (logical spot:
  after the `api-subjects` block, ~line 135, before `nodestate-retention`):
  ```json
  "footer-links": {
    "description": "Optional footer links for legal pages (imprint/privacy). Internal path or external URL.",
    "type": "object",
    "properties": {
      "imprint": { "description": "Target URL/path for the footer imprint link.", "type": "string" },
      "privacy": { "description": "Target URL/path for the footer privacy link.", "type": "string" }
    }
  }
  ```
  Decoding uses `DisallowUnknownFields()`, so the schema/struct must stay in sync.

### 3. Render layer — `web/web.go`
The patch passed `config.FooterLinksConfig` straight to the template, but the
"new tab if external" rule needs a precomputed boolean (the templates register no

      defaultPrivacyLink = "/privacy"
  )

- Add render types:
  ```go
  type FooterLink struct {
      URL      string // resolved target (internal path or external URL)
      External bool   // true => open in new tab
  }
  type FooterLinks struct {
      Imprint FooterLink
      Privacy FooterLink
  }
  ```
- Add `FooterLinks FooterLinks` field to the `Page` struct (lines 255-269).
- Add a helper:
  ```go
  func resolveFooterLink(v, def string) FooterLink {
      if v == "" {
          v = def
      }
      ext := strings.HasPrefix(v, "http://") || strings.HasPrefix(v, "https://")
      return FooterLink{URL: v, External: ext}
  }
  ```
  (`strings` is already imported in `web.go`.)
- In `RenderTemplate` (after the existing nil-guards, ~line 289), set:
  ```go
  page.FooterLinks = FooterLinks{
      Imprint: resolveFooterLink(config.Keys.FooterLinks.Imprint, defaultImprintLink),
      Privacy: resolveFooterLink(config.Keys.FooterLinks.Privacy, defaultPrivacyLink),
  }
  ```
  Setting it for every page (incl. the minimal `Page` used by the `/imprint` and
  `/privacy` handlers in `cmd/cc-backend/server.go:201-208`) means the footer
  renders correctly everywhere — no handler changes needed.

<li class="footer-list-item"><a class="link-secondary fs-5" href="{{ .FooterLinks.Imprint.URL }}" title="Imprint"{{ if .FooterLinks.Imprint.External }} target="_blank" rel="noopener noreferrer"{{ else }} rel="nofollow"{{ end }}>Imprint</a></li>
<li class="footer-list-item"><a class="link-secondary fs-5" href="{{ .FooterLinks.Privacy.URL }}" title="Privacy Policy"{{ if .FooterLinks.Privacy.External }} target="_blank" rel="noopener noreferrer"{{ else }} rel="nofollow"{{ end }}>Privacy Policy</a></li>
```

  (Handles the "key absent entirely" case; the web-layer fallback below handles

      Imprint FooterLink
      Privacy FooterLink
  }
  ```
- Add `FooterLinks FooterLinks` field to the `Page` struct (lines 255-269).
- Add a helper:
  ```go
  func resolveFooterLink(v, def string) FooterLink {
      if v == "" {
          v = def
      }
      ext := strings.HasPrefix(v, "http://") || strings.HasPrefix(v, "https://")
      return FooterLink{URL: v, External: ext}
  }
  ```
  (`strings` is already imported in `web.go`.)
- In `RenderTemplate` (after the existing nil-guards, ~line 289), set:
  ```go
  page.FooterLinks = FooterLinks{
      Imprint: resolveFooterLink(config.Keys.FooterLinks.Imprint, defaultImprintLink),
