1. eIM writes command "Enable this profile!" 2. eIM signs it Digital signature added 3. Sends to IPA Through secure bridge 4. IPA passes to chip "Here's a signed command!" 5. Chip verifies signature "I trust this sender!" 6. Chip checks counter "Not a replay!" 7. Chip executes! Flips the profile switch 8. Signed result "Here's proof I did it!" ✨ Command Complete!

đŸĒ„ The Magic Recipe

Every remote profile operation follows the same eight-step recipe: the eIM writes and signs a command, sends it through the translator, the chip verifies the signature and counter, executes the command, and creates a signed proof of completion. Like magic: but with math!

✅ Enable Turn ON â¸ī¸ Disable Turn OFF đŸ—‘ī¸ Delete Remove forever âĒ Rollback Undo last change đŸˇī¸ Set Fallback Emergency backup đŸˇī¸ Unset Fallback Remove tag ⚡ Instant Activation: enable immediately on first download!

đŸ•šī¸ The Six Buttons on the Remote

Six remote commands: Enable (turn on), Disable (turn off without deleting), Delete (remove forever: must be disabled first!), Rollback (undo), Set Fallback (emergency backup tag), and Unset Fallback. Plus Instant Activation for brand-new devices!

âœˆī¸ PRE-FLIGHT CHECKLIST Does this profile exist? Is it in the right state? Do profile policy rules allow this? Did the signature check out? All ✅ → Execute! Any ❌ → Reject!

🧮 Pre-Flight Checks Before Every Command

Before executing any command, the chip runs through a checklist: does this profile exist? Is it in the right state? Do the Profile Policy Rules allow this? Did the signature check out? Only when every check passes does the chip proceed: like a pilot's pre-flight checklist!

Disable Delete Notify Report đŸĒ„ DOMINO EFFECT A profile can have a rule: "delete me after I'm disabled." One command triggers two actions: disable now, auto-delete!

đŸŽ¯ The Domino Effect

A profile can be programmed with rules. For example: "delete me after I'm disabled." So a single disable command can trigger two actions: disable now, and auto-delete afterwards. It's like a domino effect built right into the profile itself!

🧠 PROFILE "Never disable me!" rule or "Auto-delete after disabled"

A profile can have a rule saying "delete me after I'm disabled." So one disable command can trigger two actions: disable now, auto-delete afterwards. Or a rule saying "never disable me": the chip simply rejects any disable command for that profile. Profiles have personalities!
