The client half of the host's new `os=` advert, shared once in pf-client-core:
`sanitize_os` (mDNS is unauthenticated input — lowercase `[a-z0-9._-]` tokens,
capped) and `os_icon_tokens`, the most-specific-first walk with the brand
aliases (`macos`→apple, `steamos`→steam) every platform resolves through.
`DiscoveredHost` carries the chain, `KnownHost` persists it (`serde(default)`,
elided when empty — older stores load unchanged and older clients read back
exactly what they wrote), `upsert` moves it only when carried, and `learn_os`
mirrors `learn_mac` — no-op, no disk write when unchanged — so the mark
survives the host going to sleep.
GTK shells: the card's status row leads with a recolorable symbolic glyph.
That needed real embedded assets — the shells had none — so `data/` gains the
ten `pf-os-*-symbolic` SVGs compiled into a gresource (new build.rs,
glib-build-tools) and registered on the icon theme at startup; the Adwaita
theme then tints them like every other status glyph.
WinUI shell: reactor renders raster-from-URI only, so the embedded mid-gray
PNGs (legible on both themes) materialize once into
%LOCALAPPDATA%\punktfunk\os-icons\ — the library's poster-art pattern — and
the tile's status row leads with a 16px image.
The couch UI plumbs `HostRow.os` (live advert preferred, else the store) for a
Skia glyph that is a declared follow-up; `--list-hosts` / `hosts --json` emit
the stored chain so the Decky plugin can read it. A host that advertises no
`os` renders everywhere exactly as it did before the field existed.

C2 of design/client-architecture-split.md, and the last of the session's overreach.
`--resolved-spec <path>` hands the session everything it needs already resolved —
effective settings, the host's clipboard decision, the profile's name — and in that mode it
performs ZERO store reads. It had been re-deriving all three, which meant policy was being
evaluated inside the thing that draws pixels, and that the spawner and the child could
disagree about a file either of them might have written in between. First-party spawns
(the shells, the CLI) always pass one now.
The compat path stays for hand-run `punktfunk-session --connect` and old Decky scripts —
but it calls the SAME helper, so the two modes cannot drift; it is the identical function
invoked in-process instead of by the parent. A spec that is named but unreadable fails
loudly rather than quietly falling back: a spawner that asked for exact settings must not
get store-derived ones instead.
The match-window write-back is gone too. The callback used to load-modify-save the shared
settings file from inside the renderer — one of that file's five concurrent writers, for a
value only the parent needs. It now reports `{"window":{w,h}}` on stdout and the spawner
persists it, on a real change only. A hand-run session still persists its own window,
because nobody is listening to its stdout there and the event alone would drop the value.
Verified on .21: a spec naming a profile that doesn't exist in the catalog is honoured
(proving no lookup happened), a missing spec errors instead of falling back, and the CLI's
spec file is written and cleaned up per launch.

C1 of design/client-architecture-split.md. There were four overlapping, none-complete CLIs:
the Linux shell's rich headless verbs, the Windows shell's near-none (it could not start a
stream at all), the session's own, and punktfunk-probe's diagnostics. This is the one a
script or a plugin should reach for, and it is a FRONT-END, not the brain — policy stays in
`pf-client-core` and the GUI shells keep calling it in-process. Shelling out for connects
would have traded duplicated code for a duplicated IPC protocol.
punktfunk pair | hosts list/add/forget | wake | library | launch | open
reachable | speed-test | profiles list | reset
Because it runs the same plan builder and the same wake machine as a card click, `launch`
and `open` WAKE A SLEEPING HOST — which the Linux shell's exec-style `--connect` never did;
it fired a packet at best and dialled into the void. Host references resolve through the
shared `resolve_host`, so `punktfunk launch desk` and `punktfunk://connect/desk` cannot
disagree about which box "desk" is.
Exit codes extend the session's contract so a consumer can branch without parsing prose:
0 ok, 2 connect, 3 trust, 4 renderer, 5 nothing matched what you named, 6 refused because
it needs a person. That last one is why `pair` and `reset` check for a terminal before
prompting — a CLI that blocks a CI job on a hidden question is a hang, not a UX.
Two deliberate non-features. `speed-test` measures and prints but does NOT apply: which
layer a bitrate belongs in is a decision the GUI makes with the user (global vs the bound
profile), and a CLI silently rewriting a profile is exactly the surprise that rule exists
to prevent. And `open` refuses an unknown host rather than pairing it — a URL may never
pair or trust on its own, at any surface.
`library` keeps TSV as its default output because that is what Decky's consumer parses;
`--json` is the door for tools, and the Playnite importer shells to exactly that. The
existing shell flags are untouched: they are a frozen compat contract until Decky migrates.
Verified on .21 against hand-authored stores: hosts list (TSV and JSON, with each host's
resolved profile and pins), profiles list, a launch honouring the binding ("Game"), a
one-off overriding it ("Work"), the same through `open` with `profile=`, and the refusal
codes (6 for an unknown host, 5 for `punktfunk://pair/...`).
