3	* POSIMYTH Analytics — shared client tracker base.
4	*
5	* Ship this file UNCHANGED inside every POSIMYTH plugin's `include/posimyth-sdk/`
6	* folder. Each plugin provides a tiny subclass (Posimyth_Tracker_NE / _TPAE / _TPGB)
7	* that only declares plugin-specific keys. All collection, scanning, consent-gating
8	* and transport lives here so the three plugins never drift apart.
9	*
10	* Privacy: this payload carries no email, no IP, no user names and no post content.
11	*
12	* It DOES carry the site URL, and the hub stores that URL in plaintext so support can tell which
13	* install a report came from. Earlier revisions of this comment said the hub only kept a one-way
14	* SHA-256 hash of it; that was wrong — the hub's hash is a row-dedup key that sits alongside the
15	* raw value, not a substitute for it. Do not describe this data as anonymous.
16	*
17	* The one exception to "no email" is the deactivation dialog's "I agree to be contacted" opt-in,
18	* which attaches the admin email — and only when the user ticks that box. See
19	* Posimyth_Deactivation_Survey::handle_ajax().
