da0085f1a6 feat: add observability module and wire MeshNode run() with background tasks 
Add health checks (/healthz), Prometheus metrics export (/metricsz),
and tracing spans to the P2P mesh node. MeshNode.run() starts GC and
health server as background tasks, returning a RunHandle for lifecycle
management. Health endpoint returns 503 during graceful shutdown drain.

4dadd01c6b feat: add E2E encryption module to meshservice 
X25519 key agreement + HKDF-SHA256 + ChaCha20-Poly1305 AEAD for
opt-in payload encryption. Each message uses a fresh ephemeral key
for forward secrecy. 11 new tests cover roundtrip, wrong-key
rejection, tampering, wire format integration, and edge cases.

fb6b80c81c feat: wire FAPP message handling into mesh router 
When a MeshEnvelope is delivered locally and its payload starts with a
known FAPP wire tag (0x01-0x05), MeshNode.process_incoming now delegates
to FappRouter instead of returning a raw Deliver action. Nodes without
FAPP capabilities still receive FAPP-tagged payloads as normal Deliver
actions, preserving backward compatibility.

Adds IncomingAction::Fapp variant, is_fapp_payload() helper, and three
integration tests covering the routing, passthrough, and no-router cases.

7be7287ba2 feat(mesh): add MLS-Lite to full MLS upgrade path 
crypto_negotiation module enables transitioning between crypto modes:

GroupCryptoState tracks current mode:
- MlsLite (signed/unsigned)
- FullMls (classical/hybrid)
- Upgrading (transition state)

MlsLiteBootstrap derives MLS-Lite keys from MLS epoch secret:
- Enables fallback to MLS-Lite over constrained links
- Same group can use full MLS over WiFi, MLS-Lite over LoRa

Upgrade protocol:
1. Member sends KeyPackage over fast link
2. Creator creates MLS Welcome
3. Group transitions to full MLS
4. Optionally maintains MLS-Lite fallback for constrained links

3c6eebdb00 feat(mesh): add transport capability negotiation 
TransportCapability enum classifies transports by bandwidth/MTU:
- Unconstrained (≥1 Mbps): Full MLS with PQ-KEM
- Medium (≥10 kbps): Full MLS classical
- Constrained (≥1 kbps): MLS-Lite with signature
- SeverelyConstrained (<1 kbps): MLS-Lite minimal

TransportManager now provides:
- best_transport() - highest capability transport
- recommended_crypto() - appropriate crypto mode
- supports_mls() - whether any transport handles full MLS
- select_for_size() - best transport for a given payload

CryptoMode enum with overhead estimates for each mode.

eee1e9f278 feat(mesh): add KeyPackage distribution over mesh 
Implements announce-based KeyPackage distribution for serverless MLS:

- MeshAnnounce now includes optional `keypackage_hash` field (8 bytes)
- CAP_MLS_READY capability flag for nodes with KeyPackages
- KeyPackageCache for storing received KeyPackages:
  - Indexed by mesh address
  - Multiple per address (for rotation)
  - TTL-based expiry
  - Capacity-bounded with LRU eviction
- Mesh protocol messages:
  - KeyPackageRequest (request by address or hash)
  - KeyPackageResponse (KeyPackage + hash)
  - KeyPackageUnavailable (negative response)

Protocol flow:
1. Bob announces with keypackage_hash
2. Alice requests KeyPackage via mesh
3. Bob (or relay) responds with full KeyPackage
4. Alice creates MLS Welcome, sends to Bob via mesh

- REPL commands /mesh trace, /mesh stats
- MeshEnvelope V2 with truncated addresses
- MLS-Lite lightweight encryption

bcde8b733c docs: update mesh-protocol-gaps with actual measurements 
Key findings from actual benchmarks:
- MLS KeyPackage: 306 bytes (6 LoRa fragments, ~4 sec)
- MLS Welcome: 840 bytes (17 fragments, ~10 sec)
- MLS-Lite: 129 bytes without sig, 262 with sig
- MeshEnvelope V2: 336 bytes (~18% savings over V1)

Classical MLS is LoRa-viable! Group setup takes ~14 sec at 1% duty.
Post-quantum hybrid (2.6KB KeyPackage) is still impractical.

Updated action items to reflect completed work:
- MLS-Lite implemented
- MeshEnvelope V2 implemented
- Size measurements complete

237f4360e4 fix: adjust CBOR overhead assertions to match actual measurements 
CBOR with field names has higher overhead than raw binary formats.
Updated assertions to reflect actual measured sizes:
- MeshEnvelope V1: ~410 bytes (empty payload)
- MeshEnvelope V2: ~336 bytes (~18% savings from truncated addresses)
- MLS-Lite: ~129 bytes without sig, ~262 with sig

Also fixed serde compatibility for [u8; 64] signature arrays by
converting to Vec<u8>.

a055706236 feat(mesh): add MLS-Lite lightweight encryption for constrained links 
MLS-Lite provides group encryption without full MLS overhead:
- Pre-shared group secret (QR code, NFC, or MLS epoch export)
- ChaCha20-Poly1305 symmetric encryption (same as MLS app messages)
- Per-message nonce from epoch + sequence
- Replay protection via sliding window
- Optional Ed25519 signatures

Wire overhead: ~41 bytes without signature, ~105 with signature
(vs ~174 bytes for MeshEnvelope V1)

Tradeoffs vs full MLS:
- No automatic post-compromise security (manual key rotation)
- No automatic forward secrecy (only per-epoch)
- Keys are pre-shared, not negotiated

Designed for SF12 LoRa where MLS KeyPackages are impractical.

9cbf824db6 feat(mesh): add MeshEnvelopeV2 with truncated 16-byte addresses 
S5: Compact envelope format for constrained links:
- 16-byte truncated addresses (MeshAddress) instead of 32-byte keys
- 16-byte truncated content ID
- u16 TTL and u32 timestamp (smaller than V1)
- Priority field (Low/Normal/High/Emergency)
- ~30-50 bytes savings per envelope vs V1

Full public keys are exchanged during announce phase and cached in
routing table. Envelope only needs addresses for routing.

- KeyPackage distribution over mesh unsolved
- No lightweight mode for constrained links

MLS-Lite design proposes 41-byte overhead symmetric mode:
- ChaCha20-Poly1305 with HKDF key derivation
- Optional Ed25519 signatures

e4c5868b31 feat: add client auto-reconnect, heartbeat, and connection status UI 
RPC layer (quicprochat-rpc):
- RpcClient now uses tokio::sync::Mutex<Connection> for safe reconnection
- Auto-reconnect with exponential backoff + jitter on retriable errors
- QUIC-level keepalive via quinn TransportConfig
- subscribe_push() returns Option<PushFrame> with None sentinel on break
- RpcError::is_retriable() classifies transient vs permanent errors
- ConnectionState enum (Connected/Reconnecting/Disconnected) with Display
- Configurable max_retries, base_delay, max_backoff, keepalive_secs

SDK layer (quicprochat-sdk):
- QpqClient wraps RpcClient in Arc for safe heartbeat task sharing
- start_heartbeat() spawns background task checking connection every 30s
- connection_state() exposes RPC-layer state to UI
- Reconnecting event added to ClientEvent enum
- disconnect() aborts heartbeat before closing connection

Client UI (quicprochat-client):
- TUI status bar shows Connected/Reconnecting.../Offline with color
- TUI handles Reconnecting event with attempt count display
- REPL event listener prints connection state changes
- REPL /status shows connection state instead of bool
- Both TUI and REPL call start_heartbeat() on startup

66eca065e0 feat: add in-flight RPC tracking, plugin shutdown hooks, and graceful drain 
Replace the fixed 30s sleep-based shutdown drain with actual in-flight RPC
tracking using an Arc<AtomicUsize> counter and RAII InFlightGuard. On
SIGTERM/SIGINT the server now:

1. Stops accepting new client and federation connections
2. Sends QUIC CONNECTION_CLOSE with reason "server shutting down"
3. Polls the in-flight counter until it reaches 0 (or drain timeout)
4. Logs drain progress as RPCs complete
5. Calls plugin on_shutdown hooks before exit

Also adds:
- on_shutdown hook to HookVTable (C-ABI plugin API) and ServerHooks trait
- server_in_flight_rpcs Prometheus gauge metric
- Federation connection tracking via shared in-flight counter

077f48f19c feat: wire up storage latency metrics, uptime gauge, and config timeouts 
Instrument DeliveryService (enqueue, fetch) and KeyService
(key_package_upload, key_package_fetch) with storage latency histogram
recording. Add periodic uptime gauge task (every 15s). Log effective
rpc_timeout_secs, storage_timeout_secs, and webtransport_listen at
startup to eliminate dead_code warnings on EffectiveConfig fields.

# quicproquo — Claude Code Instructions
# product.quicproquo
## Agent Team Workflow Rules
End-to-end encrypted group messaging over QUIC with MLS key agreement and post-quantum crypto.
### NEVER delete worktrees before preserving changes
When using agent teams with `isolation: "worktree"`:
1. **Before calling `TeamDelete`**, always check each worktree for uncommitted or committed changes
2. **Create a named branch** from each worktree's HEAD and push/preserve it before cleanup
3. **Preferred pattern**: use `git branch fix/<name> <worktree-HEAD-sha>` to save the work
4. If an agent reports changes, its worktree branch MUST be merged or saved before the team is deleted
## Tech Stack
### Agent team best practices
- Always have agents **commit their changes** with descriptive messages before shutting them down
- After all agents report, **list worktrees** (`git worktree list`) and **save branches** before cleanup
- When using worktree isolation, the sequence must be: agents finish → save branches → merge → TeamDelete
- Never call TeamDelete as a shortcut to kill zombie agents — use `rm -rf ~/.claude/teams/<name>` for the team metadata only, preserving worktree dirs
- Rust 1.75+, Cargo workspace (12 crates)
- Crypto: OpenMLS 0.8, ML-KEM-768, X25519, ChaCha20-Poly1305, OPAQUE-KE
- Networking: Quinn (QUIC), Tokio, Tower middleware
- Serialization: Protobuf (prost) for v2, Cap'n Proto (legacy v1)
- DB: rusqlite with bundled SQLCipher
- Build: just (justfile), cargo-deny for supply chain audit
### Git workflow
- Conventional commits: `feat:`, `fix:`, `chore:`, `docs:`, `test:`, `refactor:`
- GPG-signed commits only
- No `Co-authored-by` trailers
- No `.unwrap()` on crypto or I/O in non-test paths
- Secrets: zeroize on drop, never in logs
## Commands
```bash
just build # Build all workspace crates
just test # Run all tests
just test-core # Crypto tests only
just lint # clippy --workspace -- -D warnings
just fmt # Format check
just fmt-fix # Format fix
just proto # Rebuild protobuf codegen
just server # Build server binary
just client # Build client binary
cargo deny check # Supply chain audit (deny.toml)
```
## Architecture
```
crates/
quicprochat-core/ # Crypto primitives, MLS, double ratchet
quicprochat-proto/ # Protobuf definitions + prost codegen
quicprochat-rpc/ # RPC framework over QUIC
quicprochat-sdk/ # High-level client SDK

quicprochat-kt/ # Kotlin/JNI bindings
meshservice/ # Generic decentralized service layer (FAPP, Housing)
apps/gui/ # GUI application
proto/ # .proto source files
schemas/ # Data schemas
docker/ # Container configs
```
## Rules
- `clippy::unwrap_used` is **deny** workspace-wide -- use proper error handling
- `unsafe_code` is **warn** -- avoid unless absolutely necessary, document why
- P2P crate (`quicprochat-p2p`) pulls ~90 extra deps via iroh -- only compiled with `mesh` feature
- All crypto operations must go through quicprochat-core, never inline crypto
- Protobuf is the v2 wire format; Cap'n Proto is legacy v1 only
## Do NOT
- Use `.unwrap()` or `.expect()` outside tests -- clippy will deny it
- Add crypto primitives outside of quicprochat-core
- Enable the `mesh` feature by default (heavy dependency tree)
- Mix v1 (capnp) and v2 (protobuf) serialization in new code
- Skip `cargo deny check` before adding new dependencies

# Contributing to quicprochat
## Prerequisites
- **Rust toolchain** (stable) via [rustup](https://rustup.rs/)
- **protoc** is vendored via the `protobuf-src` crate -- no system installation needed
- Git with GPG signing configured
## Building and Testing
```sh
cargo build --workspace
cargo test --workspace
```
A `justfile` is also available for common tasks (`just build`, `just test`, `just proto`, etc.).
## Code Standards
### Commits
- **Conventional commits**: `feat:`, `fix:`, `docs:`, `chore:`, `test:`, `refactor:`
- Commits must be **GPG-signed**
- Commit messages describe *why*, not just *what*
- No `Co-authored-by` trailers
### Rust
- No `.unwrap()` on crypto or I/O operations outside of tests
- Secrets must be zeroized on drop and never logged
- No stubs, `todo!()`, or `unimplemented!()` in production code
- Prefer clarity over cleverness; avoid unnecessary abstractions
## Security Vulnerabilities
Do not open public issues for security bugs. See [SECURITY.md](SECURITY.md) for responsible disclosure instructions.
## Licensing
The server crate (`quicprochat-server`) is licensed under **AGPL-3.0**. All other crates are dual-licensed under **Apache-2.0 / MIT**. By submitting a contribution, you agree to license your work under the applicable license(s).

GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for
software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
our General Public Licenses are intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate. Many developers of free software are heartened and
encouraged by the resulting cooperation. However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.
The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community. It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server. Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.
An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals. This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing under
this license.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the
Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your version
supports such interaction) an opportunity to receive the Corresponding
Source of your version by providing access to the Corresponding Source
from a network server at no charge, through some standard or customary
means of facilitating copying of software. This Corresponding Source
shall include the Corresponding Source for any work covered by version 3
of the GNU General Public License that is incorporated pursuant to the
following paragraph.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the work with which it is combined will remain governed by version
3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU Affero General Public License from time to time. Such new versions
will be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU Affero General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU Affero General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU Affero General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU Affero General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License
along with this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer
network, you should also make sure that it provides a way for users to
get its source. For example, if your program is a web application, its
interface could display a "Source" link that leads users to an archive
of the code. There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for the
specific requirements.
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU AGPL, see
<https://www.gnu.org/licenses/>.

where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

- **Mesh networking** — iroh P2P, mDNS discovery, store-and-forward, broadcast channels
### Mesh & P2P Features
The `quicprochat-p2p` crate provides a full **serverless mesh networking stack**:
| Feature | Module | Description |
|---------|--------|-------------|
| **P2P Transport** | `P2pNode` | Direct QUIC connections via iroh with NAT traversal |
| **Mesh Identity** | `MeshIdentity` | Ed25519 keypairs with 16-byte truncated addresses |
| **Mesh Envelope** | `MeshEnvelope` | Encrypted, signed, TTL-aware message containers |
| **Store-and-Forward** | `MeshStore` | Queue messages for offline recipients |
| **Multi-Hop Routing** | `MeshRouter` | Distributed routing table, forward through intermediaries |
| **Announce Protocol** | `MeshAnnounce` | Signed peer discovery with capability flags |
| **Broadcast Channels** | `BroadcastManager` | Pub/sub with symmetric key encryption |
| **Transport Abstraction** | `TransportManager` | Iroh, TCP, LoRa — route by address type |
| **LoRa Transport** | `transport_lora` | Duty-cycle aware, fragmentation, SF12 support |
| **MLS-Lite** | `mls_lite` | Lightweight symmetric mode for constrained links |
| **FAPP** | `fapp` + `fapp_router` | Free Appointment Propagation Protocol (see below) |
#### FAPP — Decentralized Appointment Discovery
**Problem:** In Germany, finding a psychotherapist takes 3–6 months due to artificial slot visibility limits.
**Solution:** FAPP lets licensed therapists announce free slots into the mesh. Patients discover and reserve slots anonymously — no central registry.
```rust
// Therapist publishes slots
let announce = SlotAnnounce::new(
&therapist_identity,
vec![Fachrichtung::Verhaltenstherapie],
vec![Modalitaet::Praxis, Modalitaet::Video],
vec![Kostentraeger::GKV],
"80331", // PLZ only, never exact address
slots,
approbation_hash,
sequence,
);
fapp_router.broadcast_announce(announce)?;
// Patient queries anonymously
let query = SlotQuery {
fachrichtung: Some(Fachrichtung::Verhaltenstherapie),
plz_prefix: Some("803".into()),
kostentraeger: Some(Kostentraeger::GKV),
..Default::default()
};
fapp_router.send_query(query)?;
```
**Privacy model:**
- Therapist identity is **public** (bound to Approbation hash)
- Patient queries are **anonymous** (no identifying information)
- Reservations use **E2E encryption** to therapist's key
See [`docs/specs/fapp-protocol.md`](docs/specs/fapp-protocol.md) for the full protocol spec.

## Security Status
This project has **not undergone a formal third-party audit**. See the [threat model](docs/src/cryptography/threat-model.md) for details.
If you discover a security vulnerability, please report it privately.
> **This software has not undergone an independent security audit.** While it implements cryptographic best practices (MLS RFC 9420, OPAQUE, zeroization, constant-time comparisons), no third-party firm has reviewed the implementation. Do not rely on it for high-risk communications until an audit is completed. See [SECURITY.md](SECURITY.md) for our vulnerability disclosure policy.

# quicprochat — Sprint Plan
> 7 sprints synthesized from code audit, architecture analysis, and ecosystem research.
> Each sprint is ~1 week. Sprints are ordered by priority and dependency.
---
## Sprint 1 — Bug Fixes & Code Quality (Quick Wins)
Fix all known bugs, clippy warnings, and dead code before building on top.
- [x] **1.1 Fix boolean logic bug in TUI**
- `crates/quicprochat-client/src/client/v2_tui.rs:832` — remove `|| true`
- Cursor positioning always executes regardless of input state
- [x] **1.2 Fix unwrap violations in P2P router**
- `crates/quicprochat-p2p/src/routing.rs:416,419` — `.lock().unwrap()` on Mutex
- Replace with `.expect("lock poisoned")` or proper error handling
- [x] **1.3 Remove placeholder assertion in WebTransport**
- `crates/quicprochat-server/src/webtransport.rs:418` — `assert!(true);`
- [x] **1.4 Wire up unused metrics**
- `record_storage_latency()` — instrument storage layer calls

- `EffectiveConfig::rpc_timeout_secs` — apply as per-RPC deadline
- `EffectiveConfig::storage_timeout_secs` — apply as DB query timeout
- [x] **1.6 Fix remaining clippy warnings**
- Reduce function arity (2 functions with 8-9 args → use config/param structs)
- Remove useless `format!()` call
- Collapse nested conditionals
- Rename `from_str` method to avoid `FromStr` trait confusion
---
## Sprint 2 — OpenMLS 0.5 → 0.8 Migration
**CRITICAL**: OpenMLS 0.7.2 includes security patches. Staying on 0.5 is a risk.
- [x] **2.1 Migrate StorageProvider trait**
- Old `OpenMlsKeyStore` → new `StorageProvider` (most invasive change)
- Rework `DiskKeyStore` integration (must keep bincode serialization)
- Update all `group.rs` calls that interact with the key store
- [x] **2.2 Update MLS API calls**
- `self_update()` / `propose_self_update()` — add `LeafNodeParameters` arg
- `join_by_external_commit()` — add optional LeafNode params
- `Sender::NewMember` → split into `NewMemberProposal` / `NewMemberCommit`
- [x] **2.3 Handle GREASE support**
- New variants in `ProposalType`, `ExtensionType`, `CredentialType`
- Update match arms to handle unknown/GREASE values
- [x] **2.4 Update AAD handling**
- AAD no longer persisted — set before every API call generating `MlsMessageOut`
- [x] **2.5 Verify FIPS 203 alignment**
- Confirm ML-KEM-768 parameters match final FIPS 203 (not draft)
- Review hybrid KEM against RFC 9794 combination methods
- [x] **2.6 Full test suite pass**
- All 301 tests must pass with OpenMLS 0.8
- Run crypto benchmarks to check for performance regressions
---
## Sprint 3 — Client Resilience
Currently, network glitches cause the client to hang. This blocks v2 launch.
- [x] **3.1 Auto-reconnect with backoff**
- Integrate existing `retry.rs` into `RpcClient::call()` path
- Exponential backoff with jitter (already implemented, not wired)
- Configurable max retries and backoff ceiling

- Detect broken push stream and re-subscribe automatically
- Buffer missed events during reconnection window
- [x] **3.3 Heartbeat / keepalive**
- Periodic QUIC ping in TUI and REPL modes
- Detect dead connections before user notices
- [x] **3.4 SDK disconnect lifecycle**
- Add `QpcClient::disconnect()` for clean shutdown
- Proper state machine: Connected → Reconnecting → Disconnected
- [x] **3.5 Connection status UI**
- TUI: show connection state in status bar (Connected / Reconnecting / Offline)
- REPL: print status change notifications
---
## Sprint 4 — Server Hardening
Fix graceful shutdown and wire up timeouts for production readiness.
- [x] **4.1 In-flight RPC tracking**
- Replace fixed 30s shutdown delay with actual in-flight RPC counter
- Drain when counter reaches zero (with configurable max wait)
- [x] **4.2 Apply request-level timeouts**
- Wire `rpc_timeout_secs` config into per-RPC deadline enforcement
- Wire `storage_timeout_secs` into DB query timeouts
- Cancel long-running operations cleanly
- [x] **4.3 Plugin shutdown hooks**
- Add `on_shutdown` hook to `HookVTable`
- Call plugin shutdown before server exits
- [x] **4.4 Federation drain during shutdown**
- Stop accepting federation relay requests on SIGTERM
- Wait for in-flight federation RPCs before exit
- [x] **4.5 Connection draining improvements**
- Send QUIC CONNECTION_CLOSE with application reason
- WebTransport: send close frame before dropping sessions
---
## Sprint 5 — Test Coverage & CI Hardening
Address the major test coverage gaps identified in the audit.
- [x] **5.1 RPC framing unit tests**
- `crates/quicprochat-rpc/src/framing.rs` — encode/decode edge cases

- [x] **5.4 Integration tests**
- Reconnection scenario (kill server, restart, verify client recovers)
- Graceful shutdown (send SIGTERM during active RPCs, verify drain)
- Multi-node federation relay (if federation wired in Sprint 6)
- [x] **5.5 CI hardening**
- Add MSRV check (Rust 1.75 or declared minimum)
- Add cross-platform CI (macOS, Windows — at least build check)
- Add cargo-fuzz for crypto and parsing code
- Add MIRI for unsafe code in plugin-api/FFI
---
## Sprint 6 — Federation & P2P Integration
Wire up the scaffolded federation and P2P code into working features.
- [x] **6.1 Federation message routing**
- Wire `federation::routing::resolve_destination()` into `handle_enqueue`
- Route messages to remote home servers via `FederationClient::relay_enqueue()`

- [x] **6.2 Federation identity resolution**
- Cross-server user lookup (`user@remote-server`)
- KeyPackage fetching across federated nodes
- [x] **6.3 P2P client integration**
- Wire iroh P2P into client as transport option
- Fallback logic: prefer P2P direct → fall back to server relay

# MeshService
A generic decentralized service layer for mesh networks. Build any peer-to-peer service following the **Announce → Query → Response → Reserve** pattern.

```
## QuicProChat / quicprochat-p2p
This crate lives in the **product.quicproquo** workspace. Integration with the mesh stack:
- **Ed25519 seed**: `MeshIdentity::seed_bytes()` matches `ServiceIdentity::from_secret(&seed)` (same `ed25519-dalek` derivation as `quicprochat_core::IdentityKeypair`); truncated mesh address is SHA-256(pubkey)[0..16] in both layers.
- **Example transport**: integration test `crates/quicprochat-p2p/tests/meshservice_tcp_transport.rs` sends `wire::encode(ServiceMessage)` over `TcpTransport` (length-prefixed framing). For iroh/production, embed the same bytes in `MeshEnvelope` on ALPN `quicprochat/mesh/1`.
Run the test from the repo root:
```bash
cargo test -p quicprochat-p2p --test meshservice_tcp_transport
```
## Features
- **Generic Protocol**: Any service can be built on top (therapy appointments, housing, repairs, tutoring...)
- **Ed25519 Signatures**: All messages cryptographically signed
- **Verification Framework**: Multi-level trust (self-asserted, peer-endorsed, registry-verified)
- **Efficient Wire Format**: Fixed 64-byte header + CBOR payload
- **Pluggable Handlers**: Register custom services with the router
- **Built-in Services**: FAPP (psychotherapy) and Housing included
## Quick Start
```rust
use meshservice::{
capabilities,
identity::ServiceIdentity,
router::ServiceRouter,
services::fapp::{FappService, SlotAnnounce, SlotQuery, Specialism, Modality},
};
// Create identity
let identity = ServiceIdentity::generate();
// Create router with FAPP service
let mut router = ServiceRouter::new(capabilities::RELAY);
router.register(Box::new(FappService::relay()));
// Therapist announces slots
let announce = SlotAnnounce::new(
&[Specialism::CognitiveBehavioral],
Modality::VideoCall,
"104", // Postal prefix
)
.with_slots(3)
.with_profile("https://therapists.de/dr-mueller");
let msg = meshservice::services::fapp::create_announce(&identity, &announce, 1)?;
router.handle(msg, Some(identity.public_key()))?;
// Patient queries
let query = SlotQuery::new(Specialism::CognitiveBehavioral, "104");
let query_msg = meshservice::services::fapp::create_query(&identity, &query)?;
let matches = router.query(&query_msg);
println!("Found {} therapists", matches.len());
```
## Built-in Services
### FAPP (Free Appointment Propagation Protocol)
Decentralized psychotherapy appointment discovery:
| Service ID | Purpose |
|------------|---------|
| `0x0001` | Therapist slot announcements, patient queries |
```rust
use meshservice::services::fapp::{SlotAnnounce, Specialism, Modality};
let announce = SlotAnnounce::new(
&[Specialism::TraumaFocused, Specialism::CognitiveBehavioral],
Modality::InPerson,
"104",
)
.with_slots(2)
.with_profile("https://kbv.de/123");
```
### Housing
Decentralized room/apartment sharing:
| Service ID | Purpose |
|------------|---------|
| `0x0002` | Listing announcements, seeker queries |
```rust
use meshservice::services::housing::{ListingAnnounce, ListingType, amenities};
let listing = ListingAnnounce::new(ListingType::Apartment, 65, 850, "104")
.with_rooms(2)
.with_amenities(amenities::FURNISHED | amenities::BALCONY);
```
## Verification Framework
Three trust levels:
| Level | Description | Example |
|-------|-------------|---------|
| 0 - None | Bare announcement | Anonymous |
| 1 - Self-Asserted | Profile URL provided | Website link |
| 2 - Peer-Endorsed | Trusted peers vouch | Community rating |
| 3 - Registry-Verified | Official registry | KBV license |
```rust
use meshservice::verification::{Verification, TrustedVerifiers, VerificationLevel};
// Add trusted verifier
let mut verifiers = TrustedVerifiers::new();
verifiers.add(registry_public_key, "KBV Registry", VerificationLevel::RegistryVerified);
router.set_trusted_verifiers(verifiers);
// Require verification for announces
router.set_min_verification_level(2);
```
## Wire Protocol
64-byte fixed header for efficient parsing:
```
0-3 service_id (u32 LE)
4 message_type (u8)
5 version (u8)
6-7 flags (reserved)
8-23 message_id (16 bytes)
24-39 sender_address (16 bytes)
40-47 sequence (u64 LE)
48-49 ttl_hours (u16 LE)
50-57 timestamp (u64 LE)
58 hop_count (u8)
59 max_hops (u8)
60-63 payload_len (u32 LE)
---
64+ signature (64 bytes)
128+ payload (CBOR)
... verifications (optional CBOR)
```
## Building Custom Services
Implement `ServiceHandler`:
```rust
use meshservice::router::{ServiceHandler, ServiceAction, HandlerContext};
struct MyService;
impl ServiceHandler for MyService {
fn service_id(&self) -> u32 { 0x8001 } // Custom range
fn name(&self) -> &str { "MyService" }
fn handle(&self, message: &ServiceMessage, ctx: &HandlerContext)
-> Result<ServiceAction, ServiceError>
{
match message.message_type {
MessageType::Announce => Ok(ServiceAction::StoreAndForward),
MessageType::Query => {
// Find matches, respond...
Ok(ServiceAction::Handled)
}
_ => Ok(ServiceAction::Drop)
}
}
fn matches_query(&self, announce: &StoredMessage, query: &ServiceMessage) -> bool {
// Custom matching logic
true
}
}
```
## Service IDs
| ID | Service |
|----|---------|
| `0x0001` | FAPP (Psychotherapy) |
| `0x0002` | Housing |
| `0x0003` | Repair |
| `0x0004` | Tutoring |
| `0x0005` | Medical |
| `0x0006` | Legal |
| `0x0007` | Volunteer |
| `0x0008` | Events |
| `0x8000+` | Custom/User-defined |
## Examples
```bash
# FAPP demo (therapist + patient)
cargo run --example fapp_service
# Housing demo (landlord + seeker)
cargo run --example housing_service
# Multi-service mesh
cargo run --example multi_service
```
## Testing
```bash
cargo test
```

//! End-to-end encryption for service message payloads.
//!
//! Uses X25519 key agreement + HKDF-SHA256 key derivation + ChaCha20-Poly1305 AEAD.
//! Encryption is opt-in per message: the sender encrypts the payload before
//! constructing the `ServiceMessage`, and the recipient decrypts after receiving.
//!
//! ## Key model
//!
//! Each `ServiceIdentity` (Ed25519) can derive an X25519 keypair for encryption.
//! - Sender generates an ephemeral X25519 key per message (forward secrecy).
//! - Shared secret is computed via X25519 DH with the recipient's public key.
//! - HKDF derives a per-message encryption key.
//! - ChaCha20-Poly1305 encrypts the payload with a random nonce.
//!
//! ## Wire format of encrypted payload
//!
//! ```text
//! [1 byte: version = 0x01]
//! [32 bytes: sender ephemeral X25519 public key]
//! [12 bytes: nonce]
//! [N bytes: ciphertext + 16-byte Poly1305 tag]

//! Crypto mode negotiation and upgrade path.

//! # Upgrade Path
//!
//! ```text
//! MLS-Lite (constrained) → Full MLS (when high-bandwidth available)
//!
//! 1. Group running MLS-Lite over LoRa
//! 2. Member connects via WiFi/QUIC
//! 3. Member sends MLS KeyPackage over fast link
//! 4. Creator imports MLS-Lite members into MLS group
//! 5. Sends MLS Welcome + epoch secret derivation
//! 6. Group transitions to full MLS (can still use LoRa for app messages)
//! ```
//!
//! # Security Considerations
//!
//! - Upgrade requires re-keying (new epoch in MLS)
//! - Cannot downgrade without explicit action (security property)
//! - MLS-Lite epoch secret can be derived from MLS export
