1. The Zero-Telemetry Philosophy

error(first) operates on a principle of Data Minimization. We treat user sessions like production logs: transient, minimized, and purged when no longer operationally relevant. We do not use tracking pixels, behavioral profiling, or third-party marketing scripts.

2. Infrastructure & Caching Forensics

To ensure high-availability and performance, we utilize a multi-tier caching strategy. This system manages the delivery of content but does not ingest Personally Identifiable Information (PII).

A. Server-Side State (TTL Management)

Our custom caching engine (nivalis-cache.php) manages content delivery with the following parameters:

  • Page-Level Cache: Disk-based caching with a 10-hour TTL. This provides CPU relief while ensuring content refreshes twice daily.
  • Data-Level Cache (Transients): Database-heavy operations (e.g., Trending Post calculations) are cached for 1 hour to reduce database overhead.
  • Precision Invalidation: When content is updated, our system selectively purges only the affected nodes (the post, home page, and relevant archives) rather than flushing the global state.

B. Edge & Browser Caching

We utilize a “Bust-by-Version” strategy to manage static assets:

  • Asset Versioning: CSS and JS files are appended with a CRC32 hash based on their last modification time. This allows for “infinite” caching at the edge while ensuring instant updates upon file changes.
  • Browser Headers: We set max-age=0, must-revalidate. This prevents “stuck” versions in your browser while allowing CDN Edge nodes to hold a 24-hour cache for lightning-speed delivery.

3. State Management (Cookies)

We use a minimalist cookie set for functional rate-limiting.

VariableSourcePurposeTTL (Expiry)
nivalis_viewednivalis-post-views.phpPrevents “view count inflation” by rate-limiting post statistics.1 Hour
comment_author_*WordPress StandardOptional persistence of name/email for comments (User opt-in only).1 Year

Security: The nivalis_viewed cookie is set with the HttpOnly flag to prevent access by malicious client-side scripts.

4. Sub-Processors

Our infrastructure is limited to essential service providers:

5. Rights of the Operator

Users retain full rights over their data as defined by GDPR/CCPA. Since our caching system is content-centric rather than user-centric, we do not store “profiles” of your visit. Any voluntary payloads (comments or signal inputs) can be purged upon request.
