Signals from the Street

A live intelligence platform tracking institutional adoption of digital-asset and market-infrastructure initiatives.

Live site: https://streetsignals.nextfiadvisors.com

Front-End Architecture

The production UI is now a static SPA built with plain HTML/CSS/JS.

• Routing: hash-based client router (#/, #/signals, #/signals/:id, #/playbooks, #/radar, #/methodology, #/about)
• Styles: design tokens + app styles in css/
• Logic: modular JS in js/
• Data: JSON files in data/ (data.json, auto_data.json, intel_briefs.json, market_overlay.json, sources.json, taxonomy v1 files)

No build step is required.

Key Directories

• index.html - app shell
• base.css - global reset and defaults
• css/ - tokens.css, app.css
• js/ - state/data/router/route modules and bootstrap
• scripts/ - data refresh and utility scripts
• .github/workflows/ - scheduled data refresh pipeline

Local Development

git clone https://github.com/Barry-Eisenberg/streetsignals.git
cd streetsignals
python -m http.server 8000

Then open http://localhost:8000.

Validation

Run static regression checks before pushing front-end changes:

./scripts/ui_regression_check.ps1

Data Refresh

Manual refresh:

python scripts/update_signals.py

Content Builder-assisted refresh (opt-in):

set NEXTFI_CB_BASE_URL=https://nextfi-content-builder.onrender.com
set NEXTFI_CB_TIMEOUT=30
set NEXTFI_CB_USE_PROXY=1
set NEXTFI_CB_PROXY_MODEL=claude-sonnet-4-6
python scripts/update_signals.py

Re-summarize existing auto signal copy (backfill mode):

set NEXTFI_CB_BASE_URL=https://nextfi-content-builder.onrender.com
set NEXTFI_CB_USE_PROXY=1
python scripts/update_signals.py --resummarize-auto --limit 50 --dry-run
python scripts/update_signals.py --resummarize-auto

Prefill the unmapped review workflow artifacts:

python scripts/prefill_unmapped_review.py --scope strict --map-min-confidence high

This refreshes the first-pass queue, auto-accepts high-confidence rows, and rebuilds the workbook/dashboard artifacts. A daily scheduled GitHub Actions job runs the same command automatically.

Finalize dashboard-reviewed unmapped rows:

python scripts/finalize_unmapped_review.py --input path/to/unmapped_review_first_pass.edited.csv

Use the CSV exported from the dashboard's "Download Edited Full CSV" button. This single command aggregates reviewer decisions and writes accepted mappings back into data.json and auto_data.json.

Dune overlay refresh:

copy scripts/dune_queries.example.json scripts/dune_queries.json
set DUNE_API_KEY=your_api_key_here
python scripts/update_dune_metrics.py
