The dev VM is treated as untrusted, and the repo is a read-write virtiofs
mount shared with the backend host -- so a CA private key sitting in it is
a key that machine can sign with, and a leaf signed by this CA is one the
phone's pinned app accepts without question. Pinning against a CA the
attacker holds is no pinning at all.
So certificates are now generated on the machine that serves them, into
$XDG_CONFIG_HOME/ai-app/certs at 0700 with 0600 keys (AI_APP_CERTS
overrides), and config.json and session transcripts move to the XDG config
and data directories. Transcripts move for a plainer reason than the keys:
they are whole conversations, and they were world-readable at 0644.
Two smaller things fall out. The host and VM stop sharing one config,
which had already put a test token on the production backend. And state
stops living where `git clean -xdf` would take the enrollment and every
transcript with it.
State that predates the move is still read from the repo, with a warning
naming where to move it, so an existing install keeps working rather than
silently coming up on an empty config -- the precedence is covered by a
test, since picking the wrong file would otherwise be silent.
Verified: 31 tests, clippy clean; the certificate script writing 0700/0600
into an overridden directory; and the server logging the fallback and
serving from it.

A session now names a provider (what: driver kind, command, models) and
optionally a host (where: an ssh target). Keeping them independent is
what the real setup needs -- the backend runs where the phone can reach
it, which isn't where the CLI is installed -- and it means any provider
can be sent to any host rather than a machine being baked into one.
The first provider is claude-cli, named for the CLI rather than bare
"claude", which would suggest the credit-billed API. A fresh config is
seeded with it so a new install has something to spawn and a worked
example to edit; echo stays a built-in provider needing no config.
ssh.rs builds the child process either way: locally, or `ssh -T` with
BatchMode and keepalives, every argument single-quoted for the remote
shell (a working directory that tries to close the quote and start a
command is covered by a test), and `exec` so dropping the connection
takes the CLI down instead of orphaning it.
App: the spawn screen reads /providers and /hosts instead of hardcoded
lists, so config changes need no rebuild. Chip rows are FlowRow, fixing
the reported bug where a row of models that didn't fit wrapped *inside*
each chip -- one letter of "haiku" per line -- rather than onto a second
line.
Verified: 29 tests, clippy clean; the same claude-cli provider run once
locally and once over ssh, with the remote one visibly in a different
environment; an unknown host name refused with the configured list; and
the spawn screen on the emulator showing server-driven providers, hosts,
and models that wrap.

wg-setup-host.sh sets up the tunnel on the backend host: keys generated
there and kept there, wg0.conf, wg-quick enabled, and the phone's config
printed as a scannable QR. Split tunnel (AllowedIPs is only the backend
subnet), single-address addressing per PLAN.md, and the three things it
can't do for you -- router UDP forward, DDNS, hairpin check -- spelled
out at the end.
test-wg-tunnel.sh stands up a real WireGuard tunnel between two network
namespaces inside one machine, so the production posture (bind wg0 and
nothing else) is testable with no router, phone, or internet exposure.
Verified: real handshake, server listening on 10.66.0.1:8443 only, and
an authorized request from inside the tunnel answering 200 over pinned
TLS -- the leaf's 10.66.0.1 SAN is what a phone will validate too.
repo_root() now resolves from the running executable before falling back
to the compiled-in path: the repo is shared host<->VM over virtiofs at
different absolute paths with a shared target/, so a binary built on one
side and run on the other looked for its config where nothing exists.

PLAN.md: UserMessage/Answered events in the common model, the --bind dev
override (fail-closed default untouched), enrollment via the aiapp://
intent filter, Keystore-sealed token storage; phase 1 marked done with
what was verified. AGENTS.md: real layout, commands, and the lessons
that bit (tracing callsite cache in tests, adjustResize, CMP accessor
deprecation).
