[kleinbem]

Summary

• Graceful default state: Report Healthy with a sleek informational Private Cache banner instead of a red STATUS ERROR and Degraded badge when accessing without a token.
• Auto-populated inspector: Inspect a default package (jq-1.8.2) on initial visit so the explorer is never empty on load.
• Categorized sample closures: Group sample packages into Fleet (core-pi, attic-ui) and Upstream (jq, curl, glibc).
• Complete client quickstart snippets: Embed the real system cache public key (system:dCe+aNk1+Dwf3IG6OVBKcf5h0oL0hkRVqYiLN7iOJhU=) instead of placeholder comments.
• Architecture specs: Add 1-click copy for the cache public key, priority, and all configured upstream cache proxies.
• Streamlined endpoint resolution: Remove obsolete proxy redirect now that Caddy serves native CORS headers.

Summary by CodeRabbit

• New Features

  • Private-cache notices appear for unauthenticated connections. System cache details include a copyable public key, and architecture details include a copyable priority.
  • The Narinfo inspector offers separate fleet and upstream sample searches, with descriptions for fleet samples.
  • Configuration snippets show the public key for supported system caches. When no endpoint is saved, the page can use the current Kleinbem domain and inspect a preset path.
  • Upstream proxy names can be copied.

• Updates

  • Local requests use the configured endpoint directly. The architecture card shows Priority 41 and two additional upstream caches.

• Bug Fixes

  • Outdated inspection results are ignored; unauthorised responses receive a specific message. Connection checks distinguish unauthenticated access from rejected tokens.

Walkthrough

HTTP 401 handling now distinguishes requests with and without a token. The page also updates endpoint selection and inspection handling, cache key details, proxy entries, and Narinfo sample groups.

Changes: Private cache inspection

Layer / File(s)	Summary
Endpoint and private-cache response handling src/lib/attic-api.ts, src/routes/+page.svelte, src/lib/components/CacheTelemetry.svelte	Endpoint resolution trims whitespace and trailing slashes without redirecting to /proxy-cache. When no endpoint is saved, the page can use the current kleinbem.dev origin and inspect a preset path. A 401 without a token sets the connection status to healthy and shows a private-cache notice. A 401 with a token sets the status to down. Inspection run IDs prevent stale results from being processed.
Cache key and proxy information src/lib/components/CacheTelemetry.svelte, src/lib/components/ClientConfig.svelte	The system cache displays a copyable public key. The architecture card adds a copyable priority value of 41, and four proxy names are copyable with success or failure feedback. Configuration snippets use the configured public key for the system cache on matching endpoints.
Fleet and upstream Narinfo samples src/lib/components/NarinfoInspector.svelte	Sample choices are separated into Fleet and Upstream groups in the search chips and empty-results panel. Selecting a sample starts a search with its hash.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

Possibly related PRs

• kleinbem-dev/attic-ui#1: Adds /proxy-cache routing that this change removes, and introduces sample presets that this change regroups.
• kleinbem-dev/attic-ui#5: Adds tokenWithheld, which this change uses to choose the HTTP 401 error detail.

Merge Risk: Minimal · up to eb89a

The previously reported problems with rejected tokens, stale inspection results, clipboard feedback, public key scoping and missing copy buttons no longer apply at the current head. No concrete merge-blocking risk remains. The origin-based default endpoint depends on how the hosting routes requests, which this repository does not show, so confirm that routing before relying on it.

Review details

Systems and components

• observed — src (ui) was modified; 5 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in src/lib/attic-api.ts: resolveEndpoint no longer checks the browser hostname or parses the endpoint to rewrite cache.kleinbem.dev URLs to /proxy-cache; it now only trims whitespace and trailing slashes.
• observed — Modified behavior in src/lib/components/NarinfoInspector.svelte: Adds two fleet samples with descriptions and begins the separate upstream sample list, replacing the former samplePackages declaration.
• observed — Modified behavior in src/lib/components/NarinfoInspector.svelte: Replaces the single “Sample closures” chip list with separately labelled Fleet and Upstream groups. Both render their respective samples and call selectSample with the sample hash; fleet buttons include sample name and description in their title.
• observed — Modified behavior in src/lib/components/NarinfoInspector.svelte: Replaces the empty-state sample-package prompt and list with separate Fleet and Upstream sample groups. Selecting either type continues to call selectSample with its hash.

Full details: Title check

Explanation

The title names three real parts of the changeset: the default explorer state (first-visit inspection of jq and the endpoint default), fleet closures (fleet sample grouping and private-cache notice), and client keys (system cache public key in client snippets). It is long and lists several aspects rather than one main change, but it is related to the changes and not misleading.

Review comments at @src/lib/components/CacheTelemetry.svelte:
- Line 36: Update the clipboard copy failure handling in CacheTelemetry so
errors are not silently swallowed: provide visible feedback with a manual-copy
option, or propagate the error to a caller that provides that feedback. Preserve
the existing successful-copy behaviour.

Review comments at @src/lib/components/ClientConfig.svelte:
- Around line 20-21: Update the `cacheName === 'system'` condition in
`ClientConfig` to also verify that the selected Attic server is the known
endpoint for the embedded public key; use the placeholder or the selected
server’s key otherwise. Apply the same endpoint check to the corresponding key
selection in `CacheTelemetry`.

Review comments at @src/routes/+page.svelte:
- Line 113: Add an inspection run identifier to the flow around inspectPath so
that only the latest request can update the selected result, error state, or
isInspecting loading state. Ensure earlier requests cannot overwrite a
user-selected result or clear the loading state while a newer inspection is
pending.
- Around line 42-43: Update the error-message selection in the page response
branch so the informational state is used only for anonymous requests; when a
supplied token is rejected, retain and display the authentication error from the
response instead of clearing errorMessage.

Review comments at @src/lib/components/CacheTelemetry.svelte:
- Around line 241-246: Add keyboard-accessible copy buttons alongside the
Priority 41 value and each proxy entry in CacheTelemetry, matching the existing
public-key copy action so all three configuration details can be copied with one
click.
- Line 30: Replace the substring check in `isKleinbemEndpoint` with a parsed
endpoint hostname check, accepting `kleinbem.dev` and its intended subdomains
only at a hostname boundary. Preserve the existing condition for showing and
copying the fleet key so unrelated hosts such as
`cache.kleinbem.dev.example.org` never qualify.
