S4: /aiui/api/web-search proxied straight to SearXNG with no auth — anyone
reaching the web port ran searches attributed to the node's IP. Now routed
through the daemon's session-gated model proxy like the claude/ollama legs
(both nginx server blocks), forcing format=json upstream (the client never
sent it — search could 200 with HTML that parsed as nothing).
S3: the forwarder also serves the STANDALONE frontend, whose bodies carry
full history/images with no assistant loop behind them — a pasted seed
phrase went to Anthropic unscreened. The forwarder now runs the egress
secret-shape scan (G-B1) with the node's own secrets dir as deny corpus on
Claude bodies and search queries; blocked requests get a plain-language 400.
Also fixes a REAL gap in the egress tokenizer found by these tests: a JSON
key glued to a string value's first word ('content":"abandon...') dropped
that word, so an exactly-12-word seed pasted as a bare message yielded an
11-member run — checksum misses, backstop misses. Non-member words now
rescan within the token. egress 15/15 + model_proxy 10/10 green.
