Nothing behavioral except two status codes; mostly removing places where
the same rule was written down more than once and could drift.
- server/src/private.rs: the owner-only create/write helpers, which
config.rs, certs.rs, and the session dirs each had their own copy of
(certs.rs even duplicated the explanatory comment). One module owns the
modes now, so the "nothing this server writes is readable by anyone
else" property is checkable in one place.
- server/src/media.rs: the image media-type/extension table, which the
four places that have to agree on it each spelled out separately --
storing an upload, serving it back, building a content block, saving a
produced image. The differing *defaults* stay at the call sites with
the reasoning, since they genuinely differ by direction.
- routes.rs: a missing file was a 400 and an unreadable one a 400 with a
hand-rolled log line; they are now 404 and Internal respectively.
UnknownSession became NotFound, since it was the only 404-with-message.
- main.rs: xdg_dir takes the variable's value instead of reading the
environment, which drops the unsafe set_var from its test and lets the
test actually assert the relative-path rule.
- echo.rs had its own 4-byte hex generator beside session::random_hex.
- claude.rs: the two impl Translator blocks were one type's methods.
- Stale comments: phase-2 markers on shipped work, a permission-mode list
that had drifted from the CLI's, "dev-updater" as the leaf certificate's
fallback common name, a half-written sentence in build-apk.sh.
- App: the JSONArray walk written out in four fetchers, the four
near-identical BackHandlers in AppRoot, and SessionScreen's inline
fully-qualified names where the file otherwise imports.
- server/wg-test.log was committed by accident; *.log is ignored now, and
the gitignore comments describe where state actually lives.
- PLAN.md's backend layout gains the new modules and drops hosts.rs for
the ssh.rs that was built instead.
Verified: 35 server tests, clippy clean, app compiles warning-free, and a
scratch server driven over curl -- attachment upload/serve round-trip with
both a known and an unknown content type, the new 404s, transcript and
session-dir deletion, plus a real claude-cli session answering a prompt.

It is no longer "local" -- it serves over WireGuard rather than the LAN --
and it is specifically for developing new apps. Renaming the references
here at the same time keeps one name to search for across both repos.
Also drops the last references to gen-dev-cert.sh, which the in-process
certificate generation replaced: the build script and the Gradle task now
say to start the server once, and test-wg-tunnel.sh reads the
certificates from the XDG directory rather than the repo.

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.

Inbound: POST /sessions/{id}/attachments stores a picked photo under the
session; message attachmentIds become base64 image blocks in the
stream-json user message (verified live: an uploaded red PNG answered
"Red."). Outbound: image parts in tool results are decoded into the
session's files/ dir and referenced by Image events -- the transcript
stays lean -- and GET /sessions/{id}/files/{ref} serves them (verified
via the Read tool round-tripping the same PNG). The app grows an attach
button (system photo picker, upload-on-pick) and renders Image events
inline with an authenticated pinned fetch. Sent attachments are echoed
into the transcript as Image events so every device shows them.
Attachments and files are addressed under their session (a deviation
from PLAN.md's original bare /attachments -- recorded there) so their
lifecycle is the session directory's: deleting the session is still the
complete path out.

The second driver behind the same trait: claude -p with stream-json both
ways, the hidden --permission-prompt-tool stdio flag (without which no
permission ever reaches a client), text deltas streamed from raw API
events, tool_use/tool_result mapped to tool events, and can_use_tool
control requests surfaced as Question events -- plain permissions as
Allow/Deny, AskUserQuestion as one Question per sub-question with the
chosen labels sent back in updatedInput.answers keyed by question text
(wire shapes pinned by live probes against CLI 2.1.237, recorded in the
module doc). The CLI session id is persisted per session dir, so a
backend restart respawns with --resume and loses nothing. set_model
rides the control protocol and persists through the manager; the spawn
screen grows model/cwd/permission-mode fields.
Also: the dev CA now carries proper keyUsage/basicConstraints
extensions (strict verifiers reject it otherwise) -- regenerated and
re-pinned before any real phone has installed the app.
Verified: 20 unit tests + clippy clean; scripted end-to-end over the
HTTP API (AskUserQuestion round trip, Bash permission allow, streaming,
restart with --resume remembering earlier work, delete); and on the
emulator, a live haiku session asking Tea-or-coffee and acknowledging
the tapped answer.

The whole pipe behind one Driver trait and a common event model:
spawn/list/delete sessions, message + question answering, append-only
JSONL transcripts whose sequence numbers are the phone's resume cursor
(surviving backend restarts), bearer-token middleware wrapping every
route including the fallback, wg0-only binding that fails closed, and
first-run token enrollment via a terminal QR.
Verified: cargo test (10), clippy clean, and curl end-to-end over pinned
TLS -- auth rejection, spawn, streamed SSE replay/resume, /question
round trip, restart continuing seq numbers, delete removing everything.
