mrambossekandClaude Fable 5 ce1aaa332a server: send granted traffic from the address the session actually used
server-release / image (push) Successful in 15s
server-test / test (push) Successful in 30s
server-release / release (push) Successful in 30s
fmr binds two IPv4 addresses. connFor picked whichever socket of the right
family came first in the bind list, so a downtrain for a session established on
.150 went out from .151 — and every packet was dropped by the client's NAT,
which has no mapping for that pair. tcpdump on the server showed all 50 leaving;
the client saw none. Read as "100% downstream loss", which is the worst kind of
wrong: a confident measurement of something that never happened.

Sessions now record which of our own bound addresses received their traffic, and
granted sends (and delayed echo) go back out through that socket. The fallback
to a family match is kept for the case where nothing has been received yet, and
the test pins both paths — a single-homed lab can never reproduce this.

Also: the client-side halves of the same work — anonymizer (core-privacy), local
run archive with retention (core-archive), upload client, and the app's settings
and history screens.

mrambossekandClaude Opus 5 38fb73c34e server: HTTP echo + TLS reference (control-plane security measurements)
server-release / image (push) Successful in 15s
server-test / test (push) Successful in 27s
server-release / release (push) Successful in 28s
- POST /v1/echo: returns the received request head + body (base64) and the
  observed TLS parameters (version, cipher, SNI, ALPN, resumed). The client
  diffs against what it sent to detect header injection/stripping,
  transparent proxying, or TLS interception (sec.http_echo). http-echo
  added to the capability set.
- GET /v1/tls-reference: the served leaf-first DER chain + pin, so the app
  can compare an out-of-band copy against its own handshake (sec.tls_reference).
  Always available, no auth — public handshake info.
- Optional CLEARTEXT http-echo listener (ECHOLOT_HTTP_ECHO_LISTEN, default
  off) exposing only /v1/echo for the plaintext-path tampering test.

Live-smoke-tested (HTTPS echo reflected an injected header + observed
TLS1.3; cleartext variant reports tls:none); httptest unit tests added.
