Adds live-dashboard/: a small, complete Connectors example. One HTML page reads team data through a connector role. It has no backend and no key in the page.
What it is
sf.jsonc declares one team role, rates, on the frankfurter connector. It allows two read tools (currentRates.getLatest, historicalRates.getStartDate), pins base: "EUR" and symbols: ["USD","GBP","JPY","CHF"] on the server, and sets cache: "15m".
index.html imports /__spacefast/client.js, watches both tools with { every: "60s" }, and renders four rate tiles with 30-day sparklines. It also renders the real route states: loading, unbound, connect_required (with connectUrl), forbidden (the 403 connection_forbidden problem), and other errors, all using the route's own messages.
The README covers setup (register from the OpenAPI URL, connect, publish, turn on site serving or request it, and optional public serving), what the page proves, a state table, a short React useConnector snippet, and a Private Beta note.
Root README: a directory map entry, plus a note that only recipes are published.
Workflow: live-dashboard is added to the sf build matrix only.
Data source
Frankfurter (ECB reference rates) is free, open source, and needs no account or key. Its spec is at https://api.frankfurter.dev/v1/openapi.json. The tool names come from running the spec through @executor-js/plugin-openapi@1.6.11's compileOpenApiSpec, the version the control plane pins. The role validates against connectorRolesConfigSchema.
Publishing
CI builds this example but does not publish it. The publish-recipes job only covers recipes/. Serving needs a team in the Connectors program and a team connection with site serving turned on, which the deploy key can't set up. Publishing is the manual steps in the example README.
Verification
sf build live-dashboard passes with spacefast 0.9.0 and with 0.4.1 (the version CI pins). The artifact has four files, 17 KB, and no warnings.
The page was rendered in headless Chromium against the real runtime/engine/runtime/space-client/client.js, with a stub route that returns the runtime's wire shapes. Checked: ok with live Frankfurter data in light and dark at 1100px and 390px, plus unbound, connect_required, forbidden and the unavailable error. No page errors. The page sends only unpinned args ({} and {"start_date": …}).
Not run against a live Space. Nothing was published.
Summary by CodeRabbit
New Features
Added a live exchange-rate dashboard showing EUR rates for USD, GBP, JPY, and CHF, with 30-day changes and interactive charts.
Rates refresh periodically, with notices for loading, cached or stale data, connection issues, and errors.
Documentation
Added setup, serving, and deployment guidance, including connection requirements and manual publishing steps.
A no-build page that reads euro exchange rates through a team connector
role: sf.jsonc declares the role with pinned arguments and a 15-minute
cache, and index.html watches it through /__spacefast/client.js and
renders loading, data, unbound, connect_required and forbidden states.
The data source is Frankfurter's public OpenAPI spec, so anyone can
reproduce it. CI builds the example; publishing stays manual because it
needs a team connection with site serving.
render runs on every snapshot publish, including the refreshing flips on each 60s poll and focus refresh, and replaces section.innerHTML. A viewer hovering a sparkline loses the cursor line and readout until the pointer moves. (fixed by commit dc0790f) Found by Indent Review Agent
since is computed once when the module runs. A tab left open across days keeps polling historicalRates.getStartDate with the original start date, so the sparkline and "in 30 days" change cover more than 30 days, and the tab stops sharing the cached read with newer viewers.

Walkthrough
The pull request adds a live exchange-rate dashboard that reads current and historical rates through a Frankfurter connector. It adds site configuration, dashboard styling, setup documentation, and build-and-test matrix coverage. The dashboard is published manually.
Changes: Live rates dashboard
Layer / File(s)
Summary
Connector configuration and setup live-dashboard/sf.jsonc, live-dashboard/README.md
The site config defines team-scoped rate tools with pinned EUR arguments and a 15-minute cache. The README documents connector setup, pinned arguments, cache behavior, route states, and access requirements.
Rate data display live-dashboard/index.html, live-dashboard/styles.css, live-dashboard/README.md
The page watches latest and 30-day rates, displays available currency values and historical comparisons, and reports connector states and data freshness. It includes interactive sparklines and responsive light and dark themes. The README includes a React example.
Build and publishing integration live-dashboard/README.md, README.md, .github/workflows/publish.yml
The documentation describes manual publishing. The repository README describes the dashboard and its publishing requirement. The existing build-and-test matrix now includes live-dashboard.

Merge Risk: Low · previous review 6b3b4
This is a small example dashboard. Pages left open overnight will show a growing history window labelled as 30 days, and keyboard users cannot read individual daily values. Neither blocks merging, but both are worth a quick follow-up fix.
Security architecture risk: Minimal · up to 6b3b4
The dashboard adds narrowly configured reads of public exchange-rate data, without embedding credentials or automatically publishing the example. No introduced security failure was established. Authorization and serving-policy enforcement remain responsibilities of the external platform.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The intended added authority is access through one team connector role to two public exchange-rate read tools. Public serving intentionally broadens the viewer population when separately enabled. The inspected configuration does not declare write tools, secrets, or private business data; actual cross-team isolation cannot be established from it.
Trust Boundaries and Controls
inferred — A browser can alter requests independently of this page, so the security boundary is the platform route applying team binding, tool restrictions, pinned arguments, and serving policy before upstream access or cached delivery. The repository declares and documents these controls but does not prove their enforcement or ordering. No local bypass was established.
Resilience and Maintainability Implications
inferred — Retaining previously received public rate data after a failed read does not itself demonstrate disclosure of protected data. Repeated and concurrent reads are intended to share cached answers, but authorization after revocation, cache partitioning, and interruption or recovery of serving-policy changes remain external-platform coverage gaps rather than established PR failures.

- Line 114: Add keyboard access to the daily historical dates and rates handled
by the pointermove listener, either by enabling keyboard navigation through the
chart or providing an accessible date-and-rate table. Preserve the existing SVG
range label while ensuring keyboard users can inspect individual daily values.
- Around line 154-155: Update the branch that calls renderRates with now.data to
keep current rates visible while also displaying the history watcher’s state
when history fails; when history.data is stale, identify it as stale instead of
silently presenting it as current. Ensure the footer or equivalent status
display reports the history failure as well as the existing now.state.
- Line 35: Update the history watcher that uses since so its date range advances
when the UTC date changes: recompute since and recreate the watcher for the new
date. Release the previous watcher when replacing it, while preserving the
existing history request and chart behavior.

The rate tiles no longer hide the 30-day history read: when it is loading,
waiting for approval, needs a connection, is forbidden or fails, its
message takes the sparklines' place, and a failed refresh of good history
says the trends are from an earlier read. The footer shows the upstream
fetch time only when the answer carries cachedAt; otherwise it shows when
the page received the data, which a failed refresh keeps.
… add keyboard access
Refreshes that bring the same answer leave the cards alone, and a redraw
restores the day being read and the keyboard focus. The 30-day window is
worked out at each render in UTC days, so a tab left open moves to the
new day's shared read and drops the old watcher. Each sparkline is a
focusable slider: arrow keys, Page Up/Down, Home and End read one day,
with the same readout as the pointer and an aria-valuetext.
