SUBTC Protocol V7
BOT DISCOVERY PROTOCOL
SOBTC.NET speaks directly to search engines and AI crawlers in their own language. A dedicated discovery layer serves structured, machine-optimised feeds — separate from what human visitors see. Regular browsers are redirected to the homepage; only verified crawlers access the bot endpoints.
→ /bots — HTML + schema.org ItemList for Googlebot
→ /bots/ai — JSON semantic feed with semantic_hash for crawlers
→ /bots/live — Live pulse stream, rate-limited
→ /bots/manifest — Node discovery contract
✓ Pre-baked gzip payloads served from RAM — zero DB hit per request
✓ Deterministic rotation every 5 minutes — consistent signals for crawlers
✓ semantic_hash — crawlers skip re-ingestion when content is unchanged
✓ ETag + 304 Not Modified — crawlers cache efficiently
✓ Canonical IDs (oio:post:slug) for deduplication across crawlers
✓ Ephemeral expiry metadata — crawlers know content lifetime in advance
EPHEMERAL SEO SIGNALS — POST-LEVEL PROTOCOL
Every post on SOBTC.NET carries a complete machine-readable lifecycle signal set — telling search engines and crawlers exactly when to index, how to classify, and when to automatically remove. No manual intervention required.
✓ X-Robots-Tag: unavailable_after — Googlebot auto-deindexes after 24h, no manual removal needed
✓ SocialMediaPosting schema type with @id: oio:post:slug — canonical deduplication
✓ article:published_time + article:expiration_time — Open Graph lifecycle for social platforms
✓ x-visibility: public + x-retention: 24h — ephemeral content signal for crawlers
✓ link rel="alternate" application/json — machine-readable feed discovery on every page
✓ max-snippet:-1 — Googlebot extracts maximum content before expiry
This architecture enables media organisations, news agencies, and publishing systems to distribute time-sensitive content through SOBTC.NET with full lifecycle control — from real-time indexing to automatic expiry — without any platform dependency on proprietary CMS infrastructure.
