Server fixes:
- database.js: auto-create data/ directory on startup — was crashing on
fresh clone because the gitignored directory didn't exist
- better-sqlite3 upgraded to latest (13.x) for Node 26 compatibility
Network discovery:
- discoverNetwork() accepts optional subnet param; scans that range instead
of auto-detecting when provided
- New GET /api/network-subnets endpoint returns detected local interfaces
so UI can offer quick-select buttons
- Discovery modal: subnet text input + Scan button + auto-detect quick-select;
local subnet buttons populate once the modal is open
- server/index.js: pass subnet from request body to discoverNetwork()
Infra:
- React client runs on PORT=3456 in dev to avoid port conflicts
- .claude/launch.json added for one-command preview via Express (serves
the pre-built client, no port conflict with the preview tool)

Bug fixes:
- tags field was missing from INSERT/UPDATE SQL — tags never persisted
- is_public: `0 !== false` is true in JS, so private resources (is_public=0)
were silently flipped to public on every edit; fixed with explicit 0/false check
Global setting inheritance:
- One-time DB migration nulls out check_interval and timeout on all existing
resources so they inherit from global monitoring settings going forward
- Scheduler reads global check_interval and timeout from DB each cycle and
uses them as the fallback when per-resource values are null
- Create and edit modals: empty field = use global; placeholder shows the
current global value so it's clear what will be used

- HTTP method + request body: GET/POST/PUT/PATCH/DELETE/HEAD selector and body textarea for http/health checks; stored in http_method/http_body columns; monitorService sends correct axios method+data
- Alert escalation: incidents open longer than escalation_hours get forwarded to fallback_webhook and marked escalated=1; hourly cron in scheduler
- Baseline-relative slow alerts: effectiveThreshold = response_time_threshold || (baseline * 2) — adaptive threshold without manual config
- Notification grouping: pendingAlerts collected per check cycle; ≥2 alerts flush as one grouped email+webhook; individual in-app entries still saved per resource
- Rate limiting: in-memory per-IP limiter (20/min heartbeat, 60/min status-page); no external package
- App.js split: Dashboard.js (monitors list + modals) and ResourceDetail.js extracted; App.js reduced from ~1987 to ~80 lines
- formatDuration moved to utils/timeUtils.js; imported by both new components
- DB migrations: http_method, http_body, incidents.escalated columns
- 18 passing API/unit tests (node:test, zero dependencies)

- Heartbeat type: cron jobs POST to /api/heartbeat/:token to stay alive; scheduler marks
them down if no ping is received within the configured timeout window
- Alert rules: per-resource consecutive_failures_threshold now respected in handleIncident,
overriding the global setting; GET /api/resources/:id/alert-rules endpoint added
- SSL cert expiry badge: dashboard rows surface days_remaining for TLS monitors, turning
orange at ≤30 days and red at ≤7 days
- Webhook payload templates: {{name}}/{{status}}/{{url}}/{{type}}/{{message}}/{{timestamp}}
variables interpolated before POST; Slack-compatible text wrapping as fallback
- Status page visibility: is_public column per resource; GET /api/status-page returns only
public resources; Status.js updated to use the new endpoint
