Raw Blame History

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Replace the plain card feed for Pager and 433 Sensor modes with a source-directory split-view and a per-device station dashboard, each with a toggle back to the classic feed.

Architecture: #pagerDirectoryView (left panel) + #output (right feed) share a flex wrapper for the pager split; #sensorDashboardView replaces #output in sensor dashboard mode while #output continues receiving cards silently. Two new IIFE components (PagerDirectory, SensorDashboard) are notified via one-line hooks in the existing addMessage() and addSensorReading() functions. No backend changes.

Tech Stack: Vanilla JS (IIFE pattern), CSS custom properties from variables.css, SVG sparklines, Flask/Jinja2 templates, pytest for template structure tests.

File Map

Action	Path	Responsibility
Create	`static/css/components/pager-directory.css`	Flex wrap layout, directory panel, entry rows, highlight, toggle buttons
Create	`static/css/components/sensor-dashboard.css`	Station card grid, flash animations, sparkline, state-only devices
Create	`static/js/components/pager-directory.js`	`PagerDirectory` IIFE — address tracking, highlight, show/hide, reset
Create	`static/js/components/sensor-dashboard.js`	`SensorDashboard` IIFE — station cards, sparklines, flash, show/hide, reset
Modify	`templates/index.html`	Wrap `#output`, add view containers, toggle buttons, `<link>`/`<script>` tags, two hook calls, two `applyViewState` calls, two reset calls
Modify	`tests/test_app.py`	Template structure tests for new elements

Task 1: HTML scaffolding + template tests

Files:

Modify: tests/test_app.py
Modify: templates/index.html
Step 1: Write failing template tests

Add to tests/test_app.py:

def test_pager_directory_elements_present(client):
    response = client.get('/')
    assert b'id="signalViewWrap"' in response.data
    assert b'id="pagerDirectoryView"' in response.data
    assert b'id="pagerDirEntries"' in response.data
    assert b'id="pagerFeedHeader"' in response.data
    assert b'id="pagerToggleDir"' in response.data
    assert b'pager-directory.css' in response.data
    assert b'pager-directory.js' in response.data


def test_sensor_dashboard_elements_present(client):
    response = client.get('/')
    assert b'id="sensorDashboardView"' in response.data
    assert b'id="sensorDashboardGrid"' in response.data
    assert b'id="sensorToggleDash"' in response.data
    assert b'sensor-dashboard.css' in response.data
    assert b'sensor-dashboard.js' in response.data

Step 2: Run tests to confirm they fail

pytest tests/test_app.py::test_pager_directory_elements_present tests/test_app.py::test_sensor_dashboard_elements_present -v

Expected: 2 FAILED (elements not yet in template).

Step 3: Add CSS <link> tags

In templates/index.html, find this line (near line 58):

    <link rel="stylesheet" href="{{ url_for('static', filename='css/components/signal-cards.css') }}">

Add immediately after:

    <link rel="stylesheet" href="{{ url_for('static', filename='css/components/pager-directory.css') }}">
    <link rel="stylesheet" href="{{ url_for('static', filename='css/components/sensor-dashboard.css') }}">

Step 4: Add toggle buttons to #pagerStats

In templates/index.html, find this exact closing tag (after the FLEX count div, around line 812):

                        </div>
                        <div class="stats" id="sensorStats">

Change it to:

                            <div class="view-toggle-group">
                                <button class="view-toggle-btn view-toggle-btn--active" id="pagerToggleDir" onclick="PagerDirectory.show()">Directory</button>
                                <button class="view-toggle-btn" id="pagerToggleFeed" onclick="PagerDirectory.hide()">Feed</button>
                            </div>
                        </div>
                        <div class="stats" id="sensorStats">

Step 5: Add toggle buttons to #sensorStats

Find the closing </div> of #sensorStats (after the device count div, around line 816):

                        </div>
                        <div class="stats" id="wifiStats">

Change it to:

                            <div class="view-toggle-group">
                                <button class="view-toggle-btn view-toggle-btn--active" id="sensorToggleDash" onclick="SensorDashboard.show()">Dashboard</button>
                                <button class="view-toggle-btn" id="sensorToggleFeed" onclick="SensorDashboard.hide()">Feed</button>
                            </div>
                        </div>
                        <div class="stats" id="wifiStats">

Step 6: Wrap #output and add new view containers

Find this exact block in templates/index.html (around line 3600):

                <div class="output-content signal-feed" id="output">

Replace with:

                <div id="signalViewWrap">
                <div id="pagerDirectoryView" class="pdir-panel" style="display:none;">
                    <div class="pdir-header">Sources — <span id="pagerDirCount">0</span> active</div>
                    <div id="pagerDirEntries" class="pdir-entries"></div>
                </div>
                <div id="sensorDashboardView" class="sdb-view" style="display:none;">
                    <div id="sensorDashboardGrid" class="sdb-grid"></div>
                </div>
                <div class="pdir-feed-col">
                <div class="pdir-feed-header" id="pagerFeedHeader" style="display:none;">
                    <span id="pagerFeedLabel">All messages</span>
                    <button id="pagerClearHighlight" class="pdir-clear-btn" onclick="PagerDirectory.clearHighlight()" style="display:none;">clear highlight</button>
                </div>
                <div class="output-content signal-feed" id="output">

Then find the </div> that closes #output followed by <div class="status-bar"> (around line 3607-3609):

                </div>

                <div class="status-bar">

Replace with:

                </div>
                </div><!-- .pdir-feed-col -->
                </div><!-- #signalViewWrap -->

                <div class="status-bar">

Step 7: Add <script> tags

Find this line (around line 3641):

    <script src="{{ url_for('static', filename='js/components/signal-cards.js') }}"></script>

Add immediately after:

    <script src="{{ url_for('static', filename='js/components/pager-directory.js') }}"></script>
    <script src="{{ url_for('static', filename='js/components/sensor-dashboard.js') }}"></script>

Step 8: Run tests to confirm they pass

pytest tests/test_app.py::test_pager_directory_elements_present tests/test_app.py::test_sensor_dashboard_elements_present -v

Expected: 2 PASSED.

Step 9: Smoke-test the page loads without JS errors

python intercept.py

Open http://localhost:5000 in a browser. Check the DevTools console — there should be no JS errors (the new script tags reference files that don't exist yet, but that causes a network 404, not a console error that breaks the page).

Step 10: Commit

git add templates/index.html tests/test_app.py
git commit -m "feat: add HTML scaffolding for pager directory and sensor dashboard views"

Files:

Create: static/css/components/pager-directory.css
Step 1: Create the CSS file

Create static/css/components/pager-directory.css with this exact content:

/* ============================================================

Step 3: Commit

git add static/css/components/pager-directory.css
git commit -m "feat: add pager directory view CSS"

Task 3: PagerDirectory JS component

Files:

Create: static/js/components/pager-directory.js
Step 1: Create the component file

Create static/js/components/pager-directory.js with this exact content:

const PagerDirectory = (function () {
    'use strict';

    const STORAGE_KEY = 'pagerView';

    // Map<address, { count, protocol, lastSeen }>
    const addresses = new Map();
    let highlighted = null;

    // ---- Helpers ----

    function esc(str) {

        if (s < 10) return 'just now';
        if (s < 60) return `${s}s ago`;
        return `${Math.floor(s / 60)}m ago`;
    }

    // ---- Directory rendering ----

    function renderDirectory() {

        document.getElementById('pagerToggleDir')?.classList.toggle('view-toggle-btn--active', isDir);
        document.getElementById('pagerToggleFeed')?.classList.toggle('view-toggle-btn--active', !isDir);
    }

    function reset() {
        addresses.clear();
        highlighted = null;
        const entriesEl = document.getElementById('pagerDirEntries');
        const countEl   = document.getElementById('pagerDirCount');
        if (entriesEl) entriesEl.innerHTML = '';
        if (countEl)   countEl.textContent = '0';
        clearHighlight();
    }

    return { addMessage, highlight, clearHighlight, show, hide, reset, applyViewState };
})();

Step 2: Verify the script loads without errors

With the dev server running, open http://localhost:5000, switch to pager mode in the UI. Check DevTools console — no errors. Open DevTools console and run PagerDirectory — should return the object (not undefined).

Step 3: Commit

git add static/js/components/pager-directory.js
git commit -m "feat: add PagerDirectory JS component"

Task 4: Sensor dashboard CSS

        if (grid) grid.innerHTML = '';
    }

    return { addReading, show, hide, reset, applyViewState };
})();

Step 2: Verify the script loads

Open http://localhost:5000 in a browser, switch to 433 mode, open DevTools console, run SensorDashboard — should return the object.

Step 3: Commit

git add static/js/components/sensor-dashboard.js
git commit -m "feat: add SensorDashboard JS component"

Task 6: Wire up hooks, mode integration, and reset

Files:

Modify: templates/index.html
Step 1: Add hook in addMessage()

In templates/index.html, find this line inside addMessage() (around line 7247):

            const msgEl = SignalCards.createPagerCard(msg);

            output.insertBefore(msgEl, output.firstChild);

Add the hook call immediately before output.insertBefore:

            const msgEl = SignalCards.createPagerCard(msg);

            if (typeof PagerDirectory !== 'undefined') PagerDirectory.addMessage(msg);
            output.insertBefore(msgEl, output.firstChild);

Step 2: Add hook in addSensorReading()

Find this line inside addSensorReading() (around line 5771):

            const card = SignalCards.createSensorCard(msg);
            output.insertBefore(card, output.firstChild);

Replace with (the two if lines copy snr/rssi from raw data into msg so the dashboard footer can display them):

            if (data.snr  !== undefined) msg.snr  = data.snr;
            if (data.rssi !== undefined) msg.rssi = data.rssi;
            const card = SignalCards.createSensorCard(msg);
            if (typeof SensorDashboard !== 'undefined') SensorDashboard.addReading(msg);
            output.insertBefore(card, output.firstChild);

Step 3: Add applyViewState calls in switchMode()

Find these two lines in switchMode() (around line 4787):

            document.getElementById('pagerStats')?.classList.toggle('active', mode === 'pager');
            document.getElementById('sensorStats')?.classList.toggle('active', mode === 'sensor');

Add immediately after:

            if (typeof PagerDirectory  !== 'undefined') PagerDirectory.applyViewState(mode);
            if (typeof SensorDashboard !== 'undefined') SensorDashboard.applyViewState(mode);

Step 4: Add reset calls in clearOutput()

Find these lines in the clear output function (around line 7346):

            msgCount = 0;
            pocsagCount = 0;
            flexCount = 0;
            sensorCount = 0;

Add immediately before:

            if (typeof PagerDirectory  !== 'undefined') PagerDirectory.reset();
            if (typeof SensorDashboard !== 'undefined') SensorDashboard.reset();
            msgCount = 0;

Step 5: Verify pager directory end-to-end

Start python intercept.py, open http://localhost:5000, switch to Pager mode.

The output header should show Directory | Feed toggle buttons.
Click Start Decoding with a valid SDR connected (or wait for agent replay if available).
On first message: an address entry should appear in the left panel with a green dot.
Click that address entry: cards from that address get a blue left border; the feed header shows "<addr> highlighted"; clicking the same address again clears it.
Click Feed: left panel disappears, classic cards fill the full width. Click Directory: panel returns.
Refresh the page: the view preference is restored from localStorage.

If no SDR is available, manually invoke from the browser console to verify DOM updates:

PagerDirectory.addMessage({ address: '1234567', protocol: 'POCSAG-1200', message: 'TEST', timestamp: new Date().toISOString() });
PagerDirectory.addMessage({ address: '9990001', protocol: 'FLEX',        message: 'HELLO', timestamp: new Date().toISOString() });
// Expect: two entries in the directory panel
PagerDirectory.highlight('1234567');
// Expect: first entry highlighted with blue border

Step 6: Verify sensor dashboard end-to-end

Switch to 433 mode.

The header should show Dashboard | Feed toggle buttons.
Start Listening (or use console):

SensorDashboard.addReading({ model: 'Acurite-Tower', id: 42, channel: 'A', temperature: 21.4, temperature_unit: 'C', humidity: 67, battery: 'OK', snr: 14, frequency: '433.92', timestamp: new Date().toISOString() });
SensorDashboard.addReading({ model: 'Acurite-Tower', id: 42, channel: 'A', temperature: 21.6, temperature_unit: 'C', humidity: 68, battery: 'OK', snr: 14, frequency: '433.92', timestamp: new Date().toISOString() });
// Expect: one card, second call updates in place with flash + sparkline with two points
SensorDashboard.addReading({ model: 'Interlogix-PIR', id: '0x44A', state: 'active', battery: 'OK', snr: 18, frequency: '433.92', timestamp: new Date().toISOString() });
// Expect: second card with green state dot

Click Feed: dashboard hides, classic cards become visible. Click Dashboard: returns.
Switching to a different mode (e.g. ADS-B) and back: dashboard is restored.
Step 7: Run full test suite

pytest

Expected: all existing tests pass (no regressions from template edits).

Step 8: Commit

git add templates/index.html
git commit -m "feat: wire PagerDirectory and SensorDashboard into pager and sensor modes"
