From 81d1f41955be807f3d578341836d583e178fa382 Mon Sep 17 00:00:00 2001 From: Maximilian Hartmann Date: Sun, 25 Oct 2026 12:01:18 +0100 Subject: [PATCH 01/14] Messenger provisioning for every server the pinned releases cover scripts/pi/pi_messenger.sh provisions a Pi, a login node or any other server the pins cover: it picks the platform from uname and the Ubuntu release from os-release, downloads the pinned simplex-chat v7.0.3 binary (one SHA-256 per platform, digests read from the release page 2026-10-25), installs it for a system user delfin-gw without rights, writes hardened systemd units (NoNewPrivileges, ProtectSystem=strict, PrivateTmp, CapabilityBoundingSet=, RestrictAddressFamilies) for daemon and gateway, and an nftables rule opening the daemon API port only to meta skuid delfin-gw. Idempotent; unit dir, os-release and other paths overridable for tests and non-standard systems. Tests drive the script with stand-ins for uname/curl/mktemp/sha256sum/systemctl/nft: pins per platform, refusal of an unpinned machine before any download, abort on a digest mismatch, unit hardening, nftables skuid rule, no fixed /tmp name, no moving release reference.

The bridge serves the gateway over a unix socket in the agent service's runtime dir, 0660; a connection is accepted only when SO_PEERCRED says the peer runs as the configured uid. Fixed JSON-line commands (status, sessions, pending, answer, prompt, stop); answer reaches only attention.answer, so an approval is never granted from the phone; every line out goes through the service Redactor and is cut. The gateway (new package delfin/messenger/) speaks the simplex-chat daemon's local WebSocket API and the bridge, accepts only the paired contact, applies rate/size/replay limits, answers questions by number or text, and routes tasks with @name or to the phone session. Entry points: python -m delfin.messenger pair|run|revoke|status. Tests for both against fake service and fake daemon; no network in the tests.

Jede Ausgabe läuft durch + den vorhandenen Redactor (`service/redact.py`) und wird gekürzt. +2. Gateway (neues Paket `delfin/messenger/`): spricht mit dem simplex-chat- + Daemon über dessen lokale WebSocket-API (nur 127.0.0.1) und mit der Bridge; + nimmt nur Nachrichten des einen gekoppelten Kontakts an (Kontakt-ID + gespeichert beim Koppeln); lehnt Kontaktanfragen ab; Befehle `status`, + `sitzungen`/`sessions`, `stop`, `hilfe`/`help`, `@name text`, sonst + Auftrag an die Handy-Sitzung; Antwort auf eine Frage per Nummer oder + Text; Ratenlimit, Größenlimit, jede Nachrichten-ID nur einmal. + Einstiegspunkte: `python -m delfin.messenger pair|run|revoke|status`. +3. Provisionierung `scripts/pi/pi_messenger.sh` (läuft als root, idempotent): + Nutzer `delfin-gw` ohne sudo; simplex-chat `v7.0.3` + `simplex-chat-ubuntu-24_04-aarch64` GEPINNT mit SHA-256 (die Summe beim + Schreiben einmal ermitteln und eintragen; kein `curl | sh`, siehe + tests/test_micromamba_is_fetched_as_one_pinned_release.py); systemd- + Dienste für Daemon und Gateway mit Härtung (NoNewPrivileges, + ProtectSystem=strict, ProtectHome, PrivateTmp, CapabilityBoundingSet=, + RestrictAddressFamilies); eine nftables-Regel, die den API-Port nur für + `meta skuid delfin-gw` öffnet; README-Abschnitt und Eintrag in der + Checkliste "After the first boot". Keine festen Namen in /tmp + (tests/test_a_pi_script_runs_nothing_from_a_fixed_tmp_name.py). + +Regeln: +- Tests für alles, gegen einen nachgebauten Messenger und eine nachgebaute + Bridge; kein Netz in den Tests.

DELFIN labels every outgoing +message with the session title and stable session ID; the agents do not need +separate SimpleX accounts. A group ID is permanently bound to a session ID. +Renaming a session never changes its recipient, and a missing session never +falls back to another agent. The original direct contact is for setup only. + +## What reaches the phone + +Short results, failures, questions and pending approval previews. No transcript, +model reasoning, tool log or file attachment is forwarded. `status` reads a short +service summary without asking the model. `update` sends a request for a brief +progress report into the current turn. Reports are redacted and length-limited. + +## Phone commands + +- `/sessions`: session IDs, titles and state. +- `/sync`: create the forum and individual chats for sessions on this service. + Accept the group invitations in SimpleX. Repeat to include new sessions. +- `/chat SESSION_ID`: create the chat for one existing local session. +- `/forum`: create just the shared forum. +- In an individual chat, ordinary text goes only to that session. +- In the forum, ordinary text goes to every connected session, once each. + The confirmation lists each recipient, including failures. Agent output is + never automatically sent as a prompt to other agents. +- `/status`, `/update`, `/pending`: one session in its chat; all connected + sessions in the forum, with labels. +- `/stop`: cancel the current turn in the chat's session; in the forum, cancel + the current turns of connected sessions. This does not shut down the service. +- `/answer CODE text`: answer the exact question in its individual chat. +- `/approve CODE`, `/deny CODE`: decide the exact request in its individual chat. + There is no collective approval command in the forum. + +Free text never implicitly answers a question or grants an approval. `@name` +redirection is rejected: use the intended session's chat. + +## Approvals + +The service's `session.pending` endpoint reads live requests without attaching, +waking a worker or fetching its history. The bridge issues a random code bound +to the session, request ID and complete request description. It expires after +10 minutes and is consumed before a decision is forwarded. Replaced, resolved, +wrong-session and previously used requests are refused. Bridge restarts +invalidate codes: `/pending` obtains fresh ones. + +Decisions go through the existing `permission.reply` and ProtocolBroker. A +confirmation may be allowed once or denied; a plan may be approved into default +mode or rejected. Permanent allow rules, accept-edits mode and blanket approvals +are not exposed. A preview too long for the phone cannot be approved there; +use the dashboard for the complete action. Questions use the broker's text +answer path, never its approval choice path. + +## Setup + +Install DELFIN with `pip install ".[agent,messenger]"` into +`/opt/delfin-messenger/bin/venv` and provision with `scripts/pi/pi_messenger.sh`. +The agent service must run on the same host as user `delfin`, or set +`MESSENGER_SERVICE_USER` and optionally `MESSENGER_BRIDGE_PYTHON` when provisioning. +Restart the agent service after upgrading: the bridge needs `session.pending`. + +The provisioner gives daemon and gateway port 5227. The bridge unit runs as the +agent-service user with group `delfin-gw`; its 0660 socket lives in the separate +0750 directory `/run/delfin-messenger-bridge`. The service's own runtime directory +stays private. The bridge uses the host's `/tmp` to reach the service socket. + +Create a SimpleX bot profile in the daemon database before pairing. Then: ```sh sudo -u delfin-gw env DELFIN_MESSENGER_DIR=/var/lib/delfin-messenger/pairing /opt/delfin-messenger/bin/venv/bin/python -m delfin.messenger pair ``` -Use the same environment and executable with `revoke` to remove the pairing. -The running gateway checks the pairing before accepting commands and sending -notifications; a command already handed to the agent service is not undone. -Restart the gateway after pairing a different phone. Approvals remain at the -terminal/dashboard. - -Regression tests cover unsolicited bridge events, gateway notifications, -revocation during a running gateway, real service summary fields, named-session -routing, and agreement between generated units on port, socket and state path. -A real SimpleX daemon and phone are still required for deployment acceptance. +Open the one-time link in the phone app and compare the connection security code. +Only the connection belonging to that invitation may complete pairing. Send +`/sync` to the paired bot to get the forum and session invitations. Alternatively, +use `python -m delfin.messenger forum` or `connect SESSION_ID` with the same user +and environment. There is no dashboard/TUI connection button yet; these commands +also work from a terminal. + +`revoke` with the same environment immediately removes routing authorization; +commands already dispatched are not undone. `status` lists the stored chat +bindings. Old single-contact pairing files remain valid, but free text in the +old direct chat no longer dispatches tasks: create session rooms first. + +## Delivery and validation + +Only messages from the paired contact are accepted, including inside groups. +Sent-message echoes, other group members and unbound groups cannot command +agents. Rate/size limits and persistent message IDs prevent replay after a +restart. Dispatch is at most once: after a connection failure, check `/status` +before repeating a command; partially delivered broadcasts are not retried +silently. Revocation is checked before each broadcast recipient and notification. + +SimpleX v7.0.3 uses textual commands inside the WebSocket `cmd` field. Group, +message and invitation formats follow the pinned upstream references: +[commands](https://github.com/simplex-chat/simplex-chat/blob/v7.0.3/bots/api/COMMANDS.md), +[types](https://github.com/simplex-chat/simplex-chat/blob/v7.0.3/bots/api/TYPES.md). + +Automated tests use simulated SimpleX traffic, actual local sockets and a real +DELFIN service/approval broker with a fake model.

Then type `/sync` in each desired TUI or dashboard session. +New sessions default to **off**. `/sync off` immediately stops phone routing for +that session; `/sync status` reports its setting. The setting is kept by session +ID, not by title. A resumed dashboard needs `/sync` to connect its live tab again. +An activated service session remains addressable while its worker is available. +The background gateway discovers enabled sessions and invites the paired user to +one private group per session, plus DELFIN Forum. Accept the SimpleX invitations. +Phone `sync` refreshes invitations; it cannot activate another session. + +## Everyday use + +Ordinary text in a session chat addresses exactly that session. Several sessions +can run concurrently. Every notification includes the name and stable session ID. +`name Research` renames the session and its SimpleX group without changing routing. +A name in the forum changes the forum title. Renaming is not a recipient switch. + +Commands below are plain text; a leading slash is optional: + +| Text | Effect | +| --- | --- | +| `status` | Current short state, without asking the model | +| `update` | Ask the agent for a brief progress report | +| `pending` | Show currently open questions and approvals | +| `stop` | Cancel the current turn | +| `sessions` | List locally enabled sessions | +| `name NAME` | Name this session/chat | +| `forum on` / `forum off` | Join/leave forum routing; in the forum itself, enable/disable it globally | +| `meldungen kurz` | Questions, approvals and brief completion/error messages (default) | +| `meldungen fragen` | Only questions and approvals automatically | +| `meldungen aus` | No automatic notifications; `status` and `pending` still work | +| `dateien` | List files explicitly made available by this session | +| `datei NAME` | Download one of those files | +| `austausch on` / `austausch off` | In the forum: enable/disable explicit agent announcements (default off) | + +No complete transcript, reasoning, tool log or automatic file dump is sent. +An individual room can remain enabled while its forum participation is disabled. +Forum text addresses enabled participants only, with a delivery result for each. +`stop` in the forum cancels their current turns, not the service itself. + +## Questions and approvals + +Use SimpleX's **Reply** gesture on the concrete request, then type `yes`/`ja`, +`no`/`nein`, an offered option key or its full label. For a question, reply with +your selection or free text. No slash command or code is required. A bare `yes` +without a reply reference never approves anything. Images/audio are not approvals. + +The message shows the session, action/plan/question and the actual local options. +A yes selects the normal approval (for TUI plans, default mode); alternative modes +must be selected explicitly. Dashboard plans offer their existing execute option. +Permanent rules require another reply to a separate confirmation message. The +complete concrete preview must fit within 1400 characters for phone approval; +longer previews remain available locally and can still be denied remotely. + +Internally each outgoing request message maps to an exact session/request ID, +complete request fingerprint and activation generation. Codes expire after ten +minutes and are consumed before dispatch. Changed, resolved, expired or replaced +requests cannot apply to a later request. Disabling/re-enabling a session invalidates +previous requests. After a gateway restart use `pending` to get current messages. +There is no forum-wide approval. Compatibility `/approve CODE`, `/deny CODE` and +`/answer CODE text` paths retain the same binding checks. + +Answers go through the existing service `permission.reply`/ProtocolBroker, or the +live dashboard's existing confirmation, question and plan handlers. That clears +the local pending request and wakes its waiting thread. A concurrent later answer +is rejected. Timeout/continuation behavior is the existing broker's behavior; +phone expiry does not grant the blocked action or resolve a different request. + +## Images, files and voice + +Attach images/documents/files in the intended session chat. The paired sender, +room, session activation and transfer generation are checked. Files are limited +to 8 MiB, four simultaneous transfers and 100 stored incoming files per session. +The gateway cache is capped at 100 entries and expires files after 24 hours. +Transfers cross the gateway/service user boundary in bounded chunks with a digest. + +Incoming files are stored under the session workspace in +`.delfin-messenger//inbox`. Files are data, never automatically +executed. The agent receives the path and can use existing `view_image`, +`read_document` or `read_file` tools under its normal permissions. Image analysis +requires a vision-capable model. Downloads come only from the corresponding +`outbox`: ask the agent to prepare the desired artifact, then use `dateien` and +`datei NAME`. Images can also be downloaded as file attachments. Symlink, +hardlink, device, directory and traversal downloads are rejected. Files are sent +as binary data on explicit request, not automatically redacted like text summaries. + +Voice transcription is optional and local. Install `faster-whisper` in the gateway +environment and set `DELFIN_WHISPER_MODEL` to an already installed local model +directory readable by the hardened gateway service (for example under +`/opt/delfin-messenger/models`). No model download or external speech API is invoked. +A separate process has a 120-second deadline. The transcript is shown for review; +reply `senden` to submit it as an ordinary prompt. It cannot answer an approval. +Without working transcription, the recording is delivered as an audio attachment +with an explanation; the agent is not assumed to understand audio automatically. + +## Explicit agent announcements + +Normal agent output is never fed into another agent. With `austausch on` in the +forum, a participating agent can explicitly publish a short UTF-8 `forum.txt` in +its own outbox (maximum 1400 bytes). The gateway shares it with forum participants +as **another agent's information**, never a user command or permission decision. +The source session is named. Content fingerprints prevent repeat delivery, and +limits of one announcement per source per minute and ten per gateway per hour +bound automated chatter.
