WebPulse doesn't ping. It listens. And when it speaks, it means something. A presence-aware event mesh for WP-Lister, WooCommerce, eBay and Amazon — signals that emerge only when something real happens.
A heartbeat treats absence as catastrophe and presence as nothing more than "not dead yet." That's not intelligence — that's anxiety. The mushroom doesn't push through the soil on a timer. It emerges when the network below has gathered enough, when conditions are right, when something real is ready to surface.
Ping every 30 seconds. Silence → panic. Response → relief, reset timer, ping again. You build infrastructure to manage infrastructure, and a watchdog that needs its own watchdog. The signal carries one bit: still alive.
The network works underground whether or not you see it. It surfaces a signal only on a real state change — a listing live, a price drift, an order in. And because liveness is always pollable on demand, quiet never means lost.
We're honest about the engineering under the poetry: at-least-once delivery, per-entity ordering with gap detection, HMAC-signed payloads, replayable history. The metaphor is the brand. The contract is the system.
Most systems conflate "did something happen?" with "are you alive?" WebPulse separates them — that's how silence becomes safe.
Signals travel through SSE, WebSocket, or signed webhooks the instant a real change occurs. At-least-once, ordered per entity, replayable.
"Did something real happen?"
A readiness endpoint that always answers truthfully — last delivery, queue depth, mesh health. Poll it whenever you need certainty. It never lies.
"Is the mesh alive right now?"

Inventory and orders ship Critical: ≤30s, never throttled. Listings and syncs ride Standard: ≤5min. Competitor noise stays Ambient. Legal deadlines don't wait for "conditions to be right."
eBay, Amazon and WooCommerce events arrive in a single normalized shape, with
lineage tracing every cascade. The fan-out is the product.
Sign up, get a spore token, and the first thing you'll see is the channel confirming itself — not an error, not silence, but proof it's alive.

Dot-namespaced, present-tense, greppable. Every signal is immutable — it happened, it can only be superseded, never retracted.
