Alternatively, copy `frontend/public/index.html` to the server’s web root (e.g. `/var/www/html/`). +1. **Redeploy the frontend** so the live site gets the current frontend bundle and nginx/API wiring. For VMID 5000, run **`scripts/deploy-next-frontend-to-vmid5000.sh`** for the canonical frontend path or **`scripts/complete-explorer-api-access.sh`** for the broader API/nginx fix flow. References to `frontend/public/index.html` below are historical static-SPA compatibility details. 2. **Check what CSP the browser sees** – DevTools → Network → select the document request (the HTML page) → Headers → **Response Headers** → `Content-Security-Policy`. It should contain `'unsafe-eval'` in `script-src`. If the response has a CSP header **without** `'unsafe-eval'`, that header is coming from your server (nginx or app) or from a proxy (e.g. Cloudflare). Update the config that serves the explorer so its CSP includes `'unsafe-eval'`, then reload (hard refresh or incognito). 3. **If you use Cloudflare** – In the dashboard, check Transform Rules, Page Rules, or Security → Settings for any **Content-Security-Policy** (or similar) header that might override the origin. Ensure that header’s `script-src` includes `'unsafe-eval'`, or remove the override so the origin CSP is used. diff --git a/docs/EXPLORER_CODE_REVIEW.md b/docs/EXPLORER_CODE_REVIEW.md index e957901..f0b67c4 100644 --- a/docs/EXPLORER_CODE_REVIEW.md +++ b/docs/EXPLORER_CODE_REVIEW.md @@ -1,5 +1,10 @@ # Explorer Code Review +> Historical architecture snapshot: this review reflects a mixed Next.js + +> legacy static-SPA period.

Use backend freshness fields directly where present. +2. Stop deriving latest transaction age from the transactions page feed when `freshness.latest_indexed_transaction` is available. +3. Stop deriving last non-empty block from recent block scanning when `freshness.latest_non_empty_block` is available. +4. Use `mode.kind`, `mode.reason`, and `mode.scope` directly for homepage snapshot messaging. +5. Use `source` and `confidence` badges only where they improve trust and do not clutter. + +## Backward-Compatible Rollout Plan + +### Phase A + +Add fields without removing any current keys: + +- extend `/api/v2/stats` +- extend bridge status payload with `mode` and `subsystems` + +### Phase B + +Frontend prefers new fields when available and falls back to inference when absent. + +### Phase C + +Once fields are consistently present in production: + +- reduce frontend inference paths +- remove duplicate explanatory fallback logic where it is no longer needed + +## Minimum Viable Backend Implementation + +If full rollout is not possible immediately, the minimum high-leverage addition is: + +### `/api/v2/stats` + +- `freshness.chain_head` +- `freshness.latest_indexed_transaction` +- `freshness.latest_non_empty_block` +- `sampling.stats_generated_at` + +### `/explorer-api/v1/track1/bridge/status` + +- `mode.kind` +- `mode.updated_at` +- `mode.reason` +- `mode.scope` + +That alone would materially reduce frontend ambiguity. + +## Why This Contract Matters + +The frontend now presents state honestly enough that the remaining ambiguity is no longer visual.

It is a targeted public freshness contract. + +The public explorer needs explicit answers for: + +- current chain head +- current indexed head +- latest visible transaction +- last non-empty block +-
