feat(orchestrator): operator composer with signed text and voice

Stream -> Radio gets one line per station with state, play and stop,
autoplay and CSP refusals as row state and toast, and the speaking agent
pulsing there and in the Orbit and Chord views. The composer sends on all
seven channels; push-to-talk records with MediaRecorder, whisper.cpp
transcribes off the request thread under per-minute and per-hour caps,
and the recording travels only when "Aufnahme anhängen" is ticked.

Every operator message, the mayday clear, the day and night board
actions and a settings save that adds a stream origin take the passkey;
the hub verifies each signature once against the pinned keys before it
relays or acts. The container gets TMPDIR=/scratch so that verification
no longer fails on the read-only root.

A denial now signs its recipient: the inbox and the signing step resolve
it through one function, a claim set naming several agents leaves a
direct denial without recipient, and a recipient that changed after the
inbox showed it is refused with 409. operator_message returns only the
signed reason for a denial, never the agent's own words the radio row
quotes, and the permission hook hashes the signed recipient too.

 Both commands also patch the target's `.claude/settings.local.json` — the machine-local, untracked file, so a project's reviewed `.claude/settings.json` is never rewritten by an install: the caveman and ponytail plugins are enabled so their modes auto-activate on session start, and two reminder hooks are registered — `kvb-dream` points each agent at `/kvb-dream` at most once every twelve hours (stamped per session in `~/.claude/.dream-stamps/`), and `kvb-coach` runs its short form at the first prompt of every full hour, once across all agents (stamped in `~/.claude/.coach-hours/`); the global install also enables the `kvb-dream-notify.timer` systemd user timer, which recommends `/kvb-dream` in a GNOME notification daily at 17:00 local time and catches up once after a missed run. A PreToolUse gate from the `kvb-org-organize` skill blocks edits to files in a git worktree until the session holds a claim (`skills/kvb-org-organize/scripts/council.py`), and its resource watch (`skills/kvb-org-organize/scripts/watch.py`) measures disk, Docker and caches, cleans up low-risk data and blocks new heavy jobs before the disk runs out; it stays inactive until `~/.claude/agents-council/config.json` exists, and because its hooks run that config's commands outside the sandbox, the install adds `Edit(~/.claude/agents-council/**)` to `permissions.deny`, which also covers Write in every permission mode. The `kvb-org-radio` skill registers five hooks: its prompt hook and a PostToolBatch hook deliver the immediate radio (`call`, `broadcast`, `security`, `pan-pan`, `mayday`) mid-turn, a Stop hook delivers the post (`post`, `newsletter` and call receipts) when the turn ends, an `asyncRewake` Stop hook wakes an idle session for the radio, and a PreToolUse hook refuses every writing action while a mayday holds, except those of its sender and of the agents that join it with `radio.py assist`. The PreToolUse hook of the `kvb-org-queue` skill sends heavy commands through `queue.py hold` once the config sets `queue_enforce`, and holds a held command to the settings' Bash deny and ask rules, which see only `queue.py hold`. The global install also installs the MEDUSA security scanner with pipx for `kvb-check-security`, unless `medusa` is already on the PATH. Two hooks of the `kvb-org-perform` skill (`skills/kvb-org-perform/scripts/log.py`) log every Agent spawn with its task class, model and effort, and store the quality feedback a sandboxed session prints, in `~/.local/state/agents-council/subagent-model.jsonl`. Every hook runs `/usr/bin/python3 -I`, so neither the `python3` of a sandbox-writable virtualenv on the `PATH` nor `PYTHONPATH` reaches the hooks, which run outside the sandbox; older bare `python3` hook entries are rewritten. The reminder hooks run `/usr/bin/bash` and pin `PATH=/usr/bin:/bin`, and the council scripts keep only the `PATH` directories this uid cannot write (`skills/kvb-org-organize/scripts/hookpath.py`), so no binary an agent plants on the inherited `PATH` runs outside the sandbox. Existing settings are preserved.
 
-The global install also runs the Agent Orchestrator, a local review page in which the operator approves or rejects the agents' staged commits (the `kvb-git-diff` skill): it copies `orchestrator/` to `~/.local/share/kvb-orchestrator`, starts it there with `docker compose up -d --build` (restart `unless-stopped`, bound to `127.0.0.1` only, state in `~/.local/state/kvb-orchestrator`) and registers its MCP server for Claude Code at user scope. Its port is `KVB_ORCHESTRATOR_PORT` in `orchestrator/.env`; the hub page is `http://localhost:<port>/`, the MCP endpoint `/mcp`. Without docker the hub is skipped and the commit skills ask in chat. The hub reads new radio traffic aloud in maritime phraseology and takes push-to-talk input; its image builds both engines from pinned, sha256-verified sources and runs each as a separate process: Piper (`piper-tts`, GPL-3.0-or-later) with the `en_US-libritts-high` voice (904 speakers, trained on LibriTTS, CC BY 4.0, from `rhasspy/piper-voices`) and whisper.cpp (MIT) with the multilingual `ggml-base-q8_0` model (OpenAI Whisper weights, MIT). The operator's own voice is `KVB_ORCHESTRATOR_OPERATOR_VOICE` in `orchestrator/.env`. Its Tree reads only the file `pkgmgr branch tree` writes: the install clones `PKGMGR_REPO` (default the GitHub repository, never the sandbox-writable local checkout), builds the newest `v*` tag a fully trusted GPG key signed into `~/.local/share/kvb-orchestrator/pkgmgr`, and enables the `kvb-orchestrator-tree.timer` user timer, which writes `~/.local/state/pkgmgr/tree/branch-tree.json` every minute while the hub page polls; the hub mounts that directory read-only and starts no git. A signed tag without `branch tree` leaves the timer off.

A signed tag without `branch tree` leaves the timer off.
+
+Stream → Radio (`#stream/radio`) is the hub's radio interface. Its station list shows one line per station, the full name in the tooltip, with its state and a play or stop button; when the browser blocks autoplay, the stream fails or the CSP refuses its origin, the row and a toast say so, and one click starts the station. New stations play daily around the clock. While the hub reads a message aloud, the speaking agent pulses there and in the Orbit and Chord views, under the caption "<Agent> spricht" with the message's first line; under `prefers-reduced-motion` the ring stays still. The composer sends on all seven channels: post and call to one agent, newsletter, broadcast, pan-pan, security and mayday to all. "Aufnehmen" records with MediaRecorder; the hub transcribes the recording with whisper.cpp off the request thread (at most 120 s of audio, a 120 s timeout, four at a time), keeps it for replay in `~/.local/state/kvb-orchestrator/voice` (the newest 50) and puts the transcript into the field to edit; the message goes out as text, with the recording's host path and sha256 only when "Aufnahme anhängen" is ticked. The hub transcribes at most six recordings a minute and 600 s of audio an hour. Every operator message is passkey-signed, and the hub verifies the signature against the pinned keys, each once, before it relays; `operator_message(id, text, to)` answers `match` only for the signed text and recipient; for a denial the signature covers the recipient the inbox resolved at signing, and the answer's text is only the signed reason, never the agent's own words the radio row quotes. "Mayday aufheben", Abend, Sonnenuntergang, Sonnenaufgang and a settings save that adds a stream origin take the passkey the same way.
 
 The hub page loads nothing from the network: its icons come from Bootstrap Icons 1.13.1 (`orchestrator/vendor/bootstrap-icons`, MIT), inlined per page as the symbols it uses, and its 3D views from `3d-force-graph` 1.80.1 and `three` 0.186.1 (`orchestrator/vendor`, MIT, served by the hub under `/vendor/`). In the Artifacts Tree, "Löschen" on a `merged-clean` branch without skip reason, or "Alle gemergten löschen", shows the dry-run lines and asks for the passkey signature; the hub then writes a job (repository, branch, worktree and tip per item, no command) into `~/.local/state/kvb-orchestrator/cleanup/jobs`. The `kvb-orchestrator-cleanup.path` user unit runs `client/cleanup.py` on the host, which verifies the signature against the pinned keys, runs `pkgmgr branch cleanup --json --local --branch <name>` as a dry run in the repository, then `--apply` only when that plan names exactly the signed branch as `merged-clean` at the signed tip and worktree, refuses everything else unchanged, writes each result to `cleanup/results` and rewrites the tree file. The buttons stay disabled while the tree file says `delete_ready: false`.

 Without reinstalling the skills, `make orchestrator-install` installs, builds and starts only the hub, `make orchestrator-check` checks the installed hub (image, container, logs, HTTP, pinned keys, hook, runner, tree timer, disk; exit 1 on a failure), `make orchestrator-pin CREDENTIAL=<blob>` pins the passkey that "Passkey registrieren" shows, `make orchestrator-runner` enables the runner service, and `make orchestrator-hook` registers the PermissionRequest hook in `~/.claude/settings.json`, replacing an earlier Agent Orchestrator entry and keeping the file mode, after a copy to `settings.json.before-kvb-orchestrator-hook` (Claude Code reads `~/.claude/settings.local.json` only in sessions started in the home directory). Agents that reach the Docker socket are root-equivalent: until the agent VMs of core requirement 093 isolate them, the signatures do not hold against such an agent. `make watch-check` shows whether the resource watch hook is stuck (running hooks, holders of the kept queue history, age of the stored stage).
 
-For approvals the hub is only a relay: every approval of an ask, a staged commit or an operator command is signed end to end with a WebAuthn passkey held in KeePassXC (through KeePassXC-Browser, relying party `localhost`, origin `http://localhost:<port>`; ES256, EdDSA and RS256, so a hardware key can be pinned beside it). To register, open the hub at `http://localhost:<port>/` (WebAuthn needs the domain; on `127.0.0.1` the page links there), choose "Passkey registrieren" in the settings and run the host command the page shows, `python3 ~/.local/share/kvb-orchestrator/client/approval.py pin --port <port> --approvers ~/.config/kvb-orchestrator/approvers.json --credential '<blob>'`, in a terminal outside every sandbox: it pins the key in `~/.config/kvb-orchestrator/approvers.json` with mode 0600, a file no sandboxed agent can write and the hub mounts read-only; the hub never pins. Each approval, or one bulk selection, is one signature over the hashes of every item, a nonce and an expiry; each auto-approval rule is signed once. In the inbox, an operator command run with "Ausführen" shows the runner's output in a console under its row until "Schließen". "Ablehnen" on an ask, an operator row or a rule request signs the denial with its channel and optional reason (a hash no approval shares) and, after the 3 s undo, tells the requesting agent by post or by the radio class picked, never mayday; the hub verifies that signature against the pinned keys before it stores or sends anything, the hook passes the reason on only when it verifies the signature too, and a denied operator row ends as `stopped`. Agents ask for an auto-approval rule with the MCP tool `rule_request` (the rules form's limits; a request stays open for the ask lifetime of one hour, at most 20 in all, and 3 per agent name, which only spreads the queue since MCP names no caller); its row shows a dry run over the last 7 days, and only "Annehmen" with the passkey stores it. The hub stores no rule, of any kind, whose passkey assertion it cannot verify. The executors verify it themselves against the pinned keys and fail closed: the runner (`client/runner.py`, the `kvb-orchestrator-runner` user service) runs only signed commands, each signature once, recorded in `~/.local/state/kvb-orchestrator-approvals/runner.json`; the PermissionRequest hook (`client/permission_hook.py --port <port> --timeout <seconds> --approvers ~/.config/kvb-orchestrator/approvers.json --replay ~/.local/state/kvb-orchestrator-approvals/hook.json`) allows only a signed item that matches its own tool, command, cwd and session, else it leaves the decision to Claude Code's own prompt; the commit skills run `approval.py verify` on the staged tree before committing, else they ask in the terminal. With no key pinned, every executor refuses; decisions and review rejections stay unsigned. A signed rule never covers a command holding `;`, `&`, `|`, a backtick, `$`, `<`, `>`, parentheses or a line break: such a command always asks. The hub page is trusted while it asks for a signature or shows the blob to pin: whoever controls the hub container can show one item and have another signed, or hand over a key of its own. Any local process, sandboxed agents included, can also send the unsigned operator actions (messages, decision choices, board actions, review rejections, the bare ask denial `/api/asks/<id>/deny`, console dismissals) with the hub's guard headers, and the container reads the host `/tmp` for the review pages in `/tmp/kvb-git-diff`. All three close with the agent VMs of core requirement 093, like the Docker-socket gap.
