DEEPSEEK HARNESS + CORDIS
Everything is a plugin.
The paper that explains how live components can leave cleanly.
PROVIDERS
CONSUMER
MODEL PLUGIN
TOOLS PLUGIN
SESSION PLUGIN
CORDIS CONTEXT
effects + dependencies + lifecycle
AGENT LOOP
provide
require
TEMPORAL
Undo what the plugin changed
register tool → remove tool
open resource → close resource
SPATIAL
React when a dependency changes
service appears → activate
service disappears → deactivate

INSIDE THE HTTP TERMINATOR
138 documents in.
30,000 attacks out.
How the AI generated them, and why it was never allowed to say which ones worked.
WHAT THE MACHINE DID
138
documents
15,000
fragments
THE AI
reads each one
30,000
attack ideas
30,000
sites tested
~700
actually broke
WHO DECIDED WHAT
THE AI
invents the odd requests
allowed to be wrong
THE CODE
decides pass or fail
never argues, never guesses
THE PERSON
says which result matters
and why it matters
AI generates the possibilities. Code decides what survives. A person decides what any of it means.
