irisandClaude Opus 5 6f149398d0 Don't resume onto a partial from a different revision
A resume splices: it appends bytes from wherever the server is now onto
whatever is already on disk. If the file changed upstream in between, the
result is exactly the failure that survives every cheap check -- the right
number of bytes, the wrong contents, and no error anywhere. HuggingFace
files do get updated, so this is a real path rather than a theoretical one.

`If-Range` is the header for this and would have been the tidy answer, but
HuggingFace's CDN ignores it: probed today, a deliberately stale validator
still answers 206 with the ranged bytes rather than 200 with the whole
body. So the check is done here instead. A partial now has an identity file
beside it holding the ETag it was written against, written before the body
so an interrupted download still knows what it is a piece of. On resume,
the response's ETag is compared against it, and a mismatch throws the
partial away and asks again from zero. A partial with no identity at all is
not resumed either -- it could be a fragment of anything.

The sha256 HuggingFace publishes is now also checked before the file gets
its real name, so a bad one is never offered to be run. That is
belt-and-braces after the above rather than the primary defence, which is
the right order: detecting corruption after downloading gigabytes is worth
far less than not creating it.

Verified by planting one: a 60 MB partial of random bytes with an
identity file naming a revision that does not exist. The server logged
"changed upstream since the partial was written -- starting again",
restarted from zero rather than appending, and the finished file's sha256
matches the published one. Repeated the honest resume too -- cancel at
145 MB, restart, resume at 162 MB, correct hash.

Thanks to dev-updater's session for the If-Range idea and for saying to
confirm the CDN honours it rather than assume, which is exactly what it
turned out not to do.

irisandClaude Opus 5 9d29776f02 Download GGUF models from HuggingFace, watchably
The first half of the llama.cpp work Bryan asked for: browse HuggingFace,
fetch a model, and see how far it has got from any device.

The design is dev-updater's build-progress shape with the four changes its
author recommended after living with it, since a model download is an hour
where a build is two minutes:

- **A run has an id.** Without one "not downloading" means three different
  things -- finished, never started, or someone else's run ended while you
  were away -- and over an hour that ambiguity is certain rather than
  theoretical. A device compares the run it was watching to the run
  reported now.
- **Outcomes outlive their run**, so a phone that was asleep at the moment
  of completion can still find out what happened.
- **Cancel exists.** Retrofitting cancellation into a blocking loop is
  miserable, and several gigabytes over someone's data plan is not
  something to have no answer for.
- **Progress is bytes, not a parsed marker.** We own the loop, so it counts
  directly; `total` is whatever Content-Length said and nothing else, and
  stays absent when the server sends none rather than becoming a bar drawn
  from a guess.

The download owns its own thread rather than the blocking pool, which
exists for short work. It resumes through HTTP Range, and trusts the 206
rather than the request -- a server that ignores Range answers 200 with the
whole file, and appending to that would corrupt it. `truncate(false)` on
the open is load-bearing for the same reason and says so.

Searching is proxied through the server rather than done from the phone,
because the app trusts exactly one certificate -- this one -- and the
machine that must do the downloading is also the one whose view of what
exists matters.

Verified against the real HuggingFace, not a mock: searched, listed a
repository's GGUFs, downloaded 234 MB with live byte progress, cancelled
mid-flight, confirmed the partial survived, restarted and watched it resume
at 162 MB rather than 0, and let it finish. The result's sha256 matches the
one HuggingFace publishes for that file, so the resume is byte-correct and
not merely the right length. llama.cpp then loaded it and ran inference.

irisandClaude Opus 5 4cdcbd204a Put the transport above the drivers instead of inside one
ClaudeDriver::spawn called ssh::command itself, so a translator whose job
is a wire format also knew how sessions reach other machines, and every
future driver would have had to remember the same. It now emits a `Launch`
-- program, arguments, working directory -- and hands it to a `Transport`
the manager chose from the session's host.

This is the inversion Bryan asked for, and it pays for itself immediately
in a place I had reported as a UI bug: "Run on" is offered for every
provider but only the Claude driver honoured it, so choosing a host for an
echo session silently ran it locally. With the transport above the driver
that cannot be written -- EchoDriver builds no Launch, so there is nothing
to wrap and nothing to misreport. The picker still needs to stop offering
it, but the code no longer lies underneath.

crate::ssh keeps the quoting, the forced options and the remote script,
with its tests; transport.rs only decides which of the two it is. The two
failure messages move with it, since they are transport-specific -- a
missing ssh client here is a different thing to check than a program
missing from a remote PATH.

Noted in transport.rs rather than built, because nothing needs it yet: a
remote llama-server is spawned as a process but spoken to over HTTP, so a
transport eventually needs "reach this port" as well as "run this".

Verified: cargo test (35), clippy, fmt. Nothing outside transport.rs
mentions ssh now.

irisandClaude Opus 5 4e760a4a72 Separate the Claude dialect from the Claude process
claude.rs held two things that change for unrelated reasons. One spawns the
CLI, resumes it with --resume after a crash, writes lines to it and shuts it
down; the other turns a stream-json line into common events. A CLI wire
format change touches only the second, a change to how sessions are
launched only the first, and at 830 lines a reader had to work out which
half they were in.

So the translator, the pending-request bookkeeping and the answer outcome
move to session/claude/translate.rs, and all twelve tests go with them --
every one was already a translation test, replaying recorded lines with no
process involved, which is the clearest evidence the seam was already
there. 366 lines and 628, from 830 plus tests in one file.

Pure code motion: no behaviour, no renames, and the only edits are the
visibility the split makes necessary. The probing record stays in the
driver file, since it is the provenance for both halves -- the flags are
that file's, the message catalogue is what translate implements.

Verified: 35 tests pass (the same 35), clippy clean, fmt clean, and cargo
doc resolves with broken_intra_doc_links denied.

irisandClaude Opus 5 585e4a0369 Spell the driver kind the way Rust and RON do
`kind: r#claude-cli` was the config file paying for a serde default. RON is
modelled on Rust, a hyphen is not an identifier in either, and this file is
edited by hand -- so the escape existed only to write a name nobody would
have typed that way. Snake case, and it reads `kind: claude_cli`.

The same string is the one the phone compares against to decide whether to
offer models, a working directory and permission modes, so SpawnScreen.kt
moves with it. That is a wire-format change: Dev Updater delivers the
server before the APK, so between the two an installed build sees a kind it
does not recognise and drops the Claude-specific fields from the spawn
form until the APK lands. It recovers on its own, and nothing else reads
the value.

The provider *name* is left as "claude-cli". It is a label a person picks
and may edit, and sessions reference providers by it -- renaming the
default would orphan them.

irisandClaude Opus 5 9e11e860e5 Give the ssh tests one bare host instead of two copies
Two tests built the same HostConfig inline -- a name, an address, and
nothing else configured. It is now `bare_host()`, named for what it is
about: the case that proves this adds no flags of its own when it was not
told to.

irisandClaude Opus 5 c12ab7f098 Take rustfmt's defaults
The code was hand-formatted -- close to rustfmt's output but not it, mostly
in keeping chains and call arguments on one line where the formatter would
break them. That is a per-line decision every future change has to make
again, and reproducing it would mean a config whose only job is to preserve
how the code already looks.

So this is `cargo fmt` at its defaults, with no rustfmt.toml, which is
where the sibling dev-updater checkout already sits: it is clean at the
defaults today, so the two repos now agree on layout without either of them
configuring it.

Formatting only -- no behaviour, no renames, nothing reordered. Verified
after: cargo test (35 pass), cargo clippy --all-targets clean, cargo fmt
--check clean.

irisandClaude Opus 5 f014094fcd Say what the code actually does, in the three places that had drifted
A doc comment is not compiled, so nothing catches one that has outlived
what it described. `cargo doc` does catch a subset, and it was failing:
three unresolved intra-doc links in config.rs, all mine from today -- two
naming `parse`/`render` from outside the module that defines them, and one
`format` that is ambiguous with the macro. Rustdoc now runs clean with
broken_intra_doc_links denied.

auth.rs's module doc pointed at a test called `token_is_never_logged`,
which no longer exists: it was folded into the combined gating+logging test
because tracing caches callsite interest process-wide. The doc now
describes the test that is there and says why it is one test.

AGENTS.md contradicted itself twice, both checked against a running server
rather than by reading. Its curl example passed `--cacert certs/ca.pem`, a
path relative to the checkout, while the bullet above it correctly says the
CA is generated under $XDG_CONFIG_HOME -- so the documented command fails
before it connects; with the real path it returns `[]`. And it said wg0
"doesn't exist on this machine yet" as the reason for --bind 127.0.0.1,
which the section below it already contradicts: wg0 is up at 10.66.0.1, and
the actual reason is that the emulator dials 10.0.2.2 and cannot reach it.

irisandClaude Opus 5 5f8a2146e6 Ask Dev Updater for the checkout, not for the app inside it
Dev Updater's unit is a project -- a directory in a checkout -- that
produces components, so this declaration belongs at the repository root
where it can say where each half lives. `cwd` is how a component says
that, and it is what the old file was working around: sitting in `app/`,
it reached the backend with `../server/Cargo.toml` and `../server/service`,
which described the layout backwards.

So the file says what this repository produces: the backend, built and
serviced in `server/`, and then the APK, built in `app/`. The order is
unchanged and still the point -- a failing APK build leaves the phone the
APK it already had rather than half of a matched pair.

The service script gains dev-updater's note about lingering. A user
service stops at logout unless `loginctl enable-linger` is set, which for
this one matters more than for a build server: the phone reaches ai-server
whether or not anyone is logged in at the desk.

**This changes the project path, so the phone's existing entry (at
~/repos/ai-app/app) has to be removed and the checkout root added
instead**, and its components accepted once.

Verified against dev-updater's current parser rather than by reading its
schema: the declaration loads, `cargo build --release` resolves into
server/, app/build-apk.sh into app/, the service script to an absolute
path, and APK discovery from the root still finds the built APK.
`./server/service status` prints not-installed and exits 0.

irisandClaude Opus 5 19de699bfa Follow dev-updater's own config to RON
The same move, for the same reason: this file is written and read by hand,
and JSON has no comments to say why a host is configured the way it is.
Both house rules come across with it, in config.rs's `format` module and
nowhere else -- a file is the *body* of the config, so no outer parentheses
and nothing indented for them, and `Some` is implicit, which is what makes
`skip_serializing_if` on every optional field load-bearing rather than
tidiness.

The switch is outright: there is no reader for the old format. That is
invisible everywhere except here, because this file holds the enrolled
token hashes -- starting empty leaves the phone unable to talk to the
server and looks, from the phone, like the config having been lost. So a
config.json left beside the new file is named in the log and left alone,
rather than read or deleted.

One wart, documented at DriverKind: the kebab-case spelling is the string
the phone compares against, so it stays, and the file pays for it with
`kind: r#claude-cli` -- a hyphen is not a RON identifier. Renaming the
variant would change what an already-installed build is talking to.

Verified: cargo test, cargo clippy --all-targets, and a real start against
a scratch state directory -- a hand-typed config with comments and a bare
`port: 2222` loads, and what the server writes back sits at column 0 with
no Some(...) in it.

irisandClaude Opus 5 effefdeb03 Carry a service script, and declare the backend as a component
ai-server is now something Dev Updater can install, start and stop from
the phone: the project declares a Server component naming ./server/service,
and that script is where knowing about systemd and OpenRC lives.

Detection asks rather than looks -- `systemctl --user show-environment`
answering, or `rc-service --user` existing -- because a machine can carry
both binaries and an OpenRC below 0.60 has rc-service without --user.
Neither present is an error with a message, not a guess at a fallback.

Two things the script will not do. It never prompts: Dev Updater runs it
with stdin closed, so a sudo prompt would hang rather than fail, and
anything needing root exits telling you to run it yourself once. And on
OpenRC it refuses when XDG_RUNTIME_DIR is unset rather than proceeding --
user services store their state there, and the failure otherwise reads as
a broken service instead of a missing variable.

The server is declared before the app so it is built and delivered first;
a failed APK build then leaves the phone with the APK it already had
rather than half of a matched pair.

irisandClaude Opus 5 99bcc341c1 Cleanup pass: one home for duplicated logic, stale comments out
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.

irisandClaude Fable 5 56491f84b0 Follow the sibling project's rename to dev-updater
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.

irisandClaude Fable 5 65743b899d Generate the TLS certificates in process
gen-dev-cert.sh is gone. The server ensures its own certificates on start,
which removes a setup step to remember, a dependency on whatever openssl
was installed, and a second place for the "which addresses?" answer to
live -- the leaf now covers every local IPv4 plus loopback and the
emulator's host alias, so nobody maintains a hardcoded IP.

The split that mattered in the script is kept and now enforced by tests:
the CA is generated once and left alone, because the app pins it and
replacing it strands every installed copy; the leaf is cheap and reissued
every start, so covering a new address is a restart. Both are written
owner-only into a directory outside the repo.

Two things the tests caught. DirBuilder's mode applies only when the
directory is created, so a directory that already existed kept whatever
permissions it had while holding a private key -- the mode is now set
explicitly, in the session directories too. And loading the leaf into the
real RustlsConfig needs the crypto provider installed, which main does but
tests don't.

Verified end to end: deleted the certs, started the server, watched it
generate a CA and warn that installed apps now pin the wrong one, rebuilt
the APK against the new CA, and reinstalled -- the emulator connects over
a certificate that never existed as a pasted constant.

irisandClaude Fable 5 ce349af414 Drop the in-repo state fallback
Nothing has run against the host's backend yet, so there is no old config
or transcript to keep working -- the XDG paths are simply where state
lives. Removing the fallback takes repo_root() with it, since finding the
repo from the running executable existed only to locate that legacy state.

AGENTS.md gets the arrangement that replaced it: the host builds and runs
from its own clone outside the shared mount, and code reaches it by push
to gitea, which this VM's key is not authorized for.

irisandClaude Fable 5 d2d2832ec8 Keep state and keys out of the shared 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.

irisandClaude Fable 5 fff1fb49e8 Providers and hosts: what runs, and where, as independent choices
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.

irisandClaude Fable 5 29f8b31f0b WireGuard bring-up: host setup script, in-VM test tunnel, portable repo_root
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.

GET /usage serves the numbers behind Claude Code's /usage, read with the
CLI's own stored OAuth credentials (nothing to configure). The endpoint
is undocumented, so parsing is defensive -- the generic limits[] array
becomes labeled window bars, unknown kinds surface under their raw name,
and any failure degrades to an 'unavailable' snapshot with the reason.
One UsageProvider per paid service behind a caching monitor that
enforces the >=180s minimum poll regardless of phone refreshes; no
background polling at all. ureq (rustls) does the outbound call, with
the process-level CryptoProvider now chosen explicitly in main -- ureq
brings ring while axum-server brings aws-lc-rs, and with both in the
graph rustls refuses to guess.

App: a Usage screen off the session list -- per-window bars colored by
utilization with relative reset times. Verified live: 74%/26%/16%
windows rendered against the real endpoint.

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.

irisandClaude Fable 5 95d389e2b8 Phase 2 core: ClaudeDriver over stream-json, permissions and questions on the phone
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.

irisandClaude Fable 5 967fc814ab Phase 1 server: TLS + token auth, session registry, EchoDriver, SSE with cursors
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.
