README

End-user optimization, not search-engine optimization. Understand and improve what real humans and agents actually do on the page — clicks, focus heatmaps, sessions, and the human-vs-agent split GA can't see — instead of chasing rankings.

particle-academy/fancy-heuristics is the PHP/Laravel ingestion + storage + query backend for human + agent interaction analytics and Fancy UI pixel verification. It is the server half of the Fancy Pixel / Fancy Heuristics trio (paired with the @particle-academy/fancy-pixel badge embed and the @particle-academy/fancy-heuristics-js browser collector).

• Zero third-party runtime deps — illuminate/* only.
• Namespace FancyHeuristics\, facade Heuristics, config config/heuristics.php.

Install

composer require particle-academy/fancy-heuristics
php artisan vendor:publish --tag=heuristics-config      # optional
php artisan vendor:publish --tag=heuristics-migrations  # optional (auto-loaded otherwise)
php artisan migrate

The wire contract

Browser/agent clients flush JSON via navigator.sendBeacon:

POST /heuristics/collect    { siteKey, sessionId, events: [ Event, ... ], context? }
POST /heuristics/pixel      { siteKey, style, mode, visible, path, ts }

Event = {
  kind: "pageview"|"click"|"scroll"|"pointer"|"dwell",
  actor: "human"|"agent",
  path, ts,
  x?, y?, vw?, vh?, scrollPct?, dwellMs?, targetId?, label?, meta?
}

// Once-per-session acquisition/audience context — sent on the FIRST batch only.
context? = {
  referrer?, utm?: { source?, medium?, campaign?, term?, content? },
  lang?, tz?, screenW?, screenH?, dpr?
}

On collect, the package upserts a derived session row per (siteKey, sessionId): acquisition (referrer/referrer_host + utm_*), audience (device/os/browser classified from the request User-Agent with a self-contained regex — no third-party UA parser — plus lang/tz/screen_*), and engagement (pageviews, events, landing_path/exit_path, duration_ms, is_bounce). The raw User-Agent is truncated and stored; the IP is never stored raw (pixel pings hash it).

Cross-origin clients: these endpoints are posted from browsers on other origins (every site that embeds the Fancy Pixel). They run on the stateless api group (no CSRF 419) and, by default, ship CORS headers + answer the OPTIONS preflight via the bundled HandleHeuristicsCors middleware — so a fresh install works cross-origin with no extra setup. Restrict who may beacon with heuristics.routes.cors.allowed_origins, or set heuristics.routes.cors.enabled (env HEURISTICS_ROUTE_CORS) to false to manage CORS yourself (e.g. Laravel's config/cors.php). Don't do both — two layers would emit a duplicate Access-Control-Allow-Origin.

Facade

use FancyHeuristics\Facades\Heuristics;

Heuristics::record($event);                 // persist one event
Heuristics::collect($payload, $ua);         // persist a batch + upsert its session
Heuristics::ingest($payload, $ua);          // same, and returns accepted / rejected-by-index
Heuristics::ping($ping);                    // persist a pixel liveness beacon
Heuristics::heatmap($siteKey, $path, null, 30); // normalised grid of pointer/click hits (range optional)
Heuristics::events($siteKey, [...]);        // raw events, filtered
Heuristics::sessionStats($siteKey, 30);     // sessions + counts by actor & kind (range optional)
Heuristics::prune();                        // delete data past its retention window

Wire v2 and the event names

/collect accepts two wire formats on the same route. A batch with schemaVersion: 2 carries a batchId (a replay returns the first result with replayed: true and stores nothing), and each event carries an eventId (stored once per site) and a <domain>.<verb> name:

A name that is not registered is rejected (unknown_name). Register your own in heuristics.names. v2 events store the route name and pattern, the page title (on ui.view only), and the activated control as component, part, instance, role and target_name, each bounded. With no pattern from the host, one is derived from the path (numeric, UUID and long hex segments become :id).

v1 producers keep working and are mapped at ingest: pageview to ui.view, click to ui.activate, dwell to engage.time, scroll to engage.scroll, pointer to pointer.sample. An agent click becomes agent.tool (from the relay, meta.via = "relay") or agent.act, and is stored with kind agent, so it no longer counts as a click. A v1 label is kept as props.legacy_label and never becomes a target name.

Rows stored before this release can be mapped the same way:

php artisan heuristics:backfill-taxonomy --dry-run   # counts, writes nothing
php artisan heuristics:backfill-taxonomy             # asks first in production

Count rows per kind on the real database before running it, and size --chunk from that count.

Ingest limits

POST {prefix}/collect is public, so every batch is bounded (heuristics.limits): events per batch, key and path lengths, label length, meta keys and bytes (flat scalars only), coordinates, scroll percentage, dwell, and timestamp skew. Paths are stored without their query string or fragment. A bad envelope is a 422; a bad event is skipped and reported:

{ "ok": true, "replayed": false, "accepted": 4, "rejected": 1,
  "errors": [{ "index": 2, "code": "invalid_path" }] }

The response never echoes a submitted value. The events and their session rollup are written in one transaction.

Retention

php artisan heuristics:prune --dry-run   # counts per data class, deletes nothing
php artisan heuristics:prune             # delete

Windows come from heuristics.retention_days (raw events, 90) and heuristics.retention.* (pointer samples 14, pixel pings 90, sessions 395, ingest receipts 7). Schedule it daily. These are product defaults, not legal advice.

Pixel pings store HMAC-SHA256(key, ip), never the IP. The key is heuristics.ip_hash_key, defaulting to the app key.

GA-parity reports

Each takes a $site, a date $range, and an optional $actor filter ('human', 'agent', or null = all). $range is either an int (last N days) or ['from' => Carbon|string, 'to' => Carbon|string] — both compared against the session's started_at. All return primitive, JSON-friendly arrays.

Heuristics::acquisition($site, 30);                  // referrer hosts, utm, direct vs referral
Heuristics::audience($site, 30);                     // device / browser / os / language
Heuristics::timeseries($site, 30, 'day', false);     // sessions+pageviews per bucket (day|week|month)
Heuristics::sessionsSummary($site, 30);              // totals, avg duration, bounce rate, pages/session
Heuristics::topPages($site, 30);                     // top paths by pageviews
Heuristics::entryPages($site, 30);                   // landing pages by session
Heuristics::exitPages($site, 30);                    // exit pages by session
Heuristics::topElements($site, 30);                  // most-activated controls (component · part · instance · name)
Heuristics::eventNames($site, 30);                   // event counts by <domain>.<verb> name
Heuristics::realtime($site);                         // sessions active in the last 5 minutes

timeseries(..., $splitActor: true) adds human_sessions / agent_sessions to every bucket.

Pixel verification

heuristics_sites registers each site to re-poll. The verifier fetches the URL server-side and runs the shared detection — the stable data-fancy-badge marker or the literal "Powered by Fancy UI" wordmark (the exact same two signals the showcase's ScanShowcaseSubmission scanner uses, kept in one place in HeuristicsPixelDetector). It updates visible / pixel_status / last_verified_at and fires PixelVerificationPassed / PixelVerificationFailed for the host to toggle a listing.

Run twice daily:

// bootstrap/app.php
use Illuminate\Console\Scheduling\Schedule;

->withSchedule(function (Schedule $schedule) {
    $schedule->command('heuristics:verify-pixels')
        ->cron(config('heuristics.verify.cron')); // default 03:00 & 15:00
})

php artisan heuristics:verify-pixels            # all sites
php artisan heuristics:verify-pixels --site=KEY # one site

Fetch safety

A site's URL is supplied by whoever registered it, and the verifier fetches it from your server, so the default fetcher (SafePageFetcher) only reaches the public internet:

• http / https only, no credentials in the URL, canonical hosts only (decimal / octal / hex IPv4 spellings are refused);
• every address the host resolves to must be public: no loopback, RFC 1918, link-local or cloud metadata (169.254.169.254), CGNAT, multicast, reserved, IPv6 ULA / link-local, or IPv4-mapped forms of those;
• the connection is pinned to the address it validated (CURLOPT_RESOLVE), so DNS rebinding cannot swap it between the check and the connect;
• redirects are followed by hand, at most verify.max_redirects (3), and each hop is checked and pinned again;
• the body is capped at verify.max_bytes (2 MB) on the wire, and verify.timeout still applies.

A refusal is a failed verification with the reason fetch refused: ….

If you need a different policy (an egress proxy, an allowlist), implement FancyHeuristics\Contracts\PageFetcher and set heuristics.verify.fetcher to your class, or rebind the contract in a service provider. Your fetcher then owns these guarantees.

Residual gaps: the pin is a cURL option, so it does not apply if your app routes Laravel's HTTP client through a non-cURL handler (without the cURL extension the fetcher refuses rather than fetch unpinned); and if the process has HTTP_PROXY / HTTPS_PROXY set, the proxy resolves the name itself.
