-# Repository Guidelines
-
-Keep code well structured, modular, and not monolithic. If modules get to big, consider submodules structure.
-
-Make sure all tests pass for Python (`pytest`), Ruby (`rspec`), and JavaScript (`npm test`).
-
-Make sure all code is properly inline documented (PDoc, RDoc, JSDoc, et.c). We do not want any undocumented code.
-
-Make sure all code is 100% unit tested. We want all lines, units, and branches to be thouroughly covered by tests.
-
-New source files should have Apache v2 license headers using the exact string `Copyright © 2025-26 l5yth & contributors`.
-
-Run linters for Python (`black`) and Ruby (`rufo`) to ensure consistent code formatting.
-
-## Project Structure & Module Organization
-The repository splits runtime and ingestion logic. `web/` holds the Sinatra dashboard (Ruby code in `lib/potato_mesh`, views in `views/`, static bundles in `public/`).
-
-`data/` hosts the Python Meshtastic ingestor plus migrations and CLI scripts. API fixtures and end-to-end harnesses live in `tests/`. Dockerfiles and compose files support containerized workflows.
-
-`matrix/` contains the Rust Matrix bridge; build with `cargo build --release` or `docker build -f matrix/Dockerfile .`, and keep bridge config under `matrix/Config.toml` when running locally.
-
-## Build, Test, and Development Commands
-Run dependency installs inside `web/`: `bundle install` for gems and `npm ci` for JavaScript tooling. Start the app with `cd web && API_TOKEN=dev ./app.sh` for local work or `bundle exec rackup -p 41447` when integrating elsewhere.
-
-Prep ingestion with `python -m venv .venv && pip install -r data/requirements.txt`; `./data/mesh.sh` streams from live radios. `docker-compose -f docker-compose.dev.yml up` brings up the full stack.
-
-Container images publish via `.github/workflows/docker.yml` as `potato-mesh-{service}-linux-$arch` (`web`, `ingestor`, `matrix-bridge`), using the Dockerfiles in `web/`, `data/`, and `matrix/`.
-
-## Coding Style & Naming Conventions
-Use two-space indentation for Ruby and keep `# frozen_string_literal: true` at the top of new files. Keep Ruby classes/modules in `CamelCase`, filenames in `snake_case.rb`, and feature specs in `*_spec.rb`.
-
-JavaScript follows ES modules under `public/assets/js`; co-locate components with `__tests__` folders and use kebab-case filenames. Format Ruby via `bundle exec rufo .` and Python via `black`. Skip committing generated coverage artifacts.
-
-## Flutter Mobile App (`app/`)
-The Flutter client lives in `app/`. Keep only the mobile targets (`android/`, `ios/`) under version control unless you explicitly support other platforms. Do not commit Flutter build outputs or editor cruft (`.dart_tool/`, `.flutter-plugins-dependencies`, `.idea/`, `.metadata`, `*.iml`, `.fvmrc` if unused).
-
-Install dependencies with `cd app && flutter pub get`; format with `dart format .` and lint via `flutter analyze`. Run tests with `cd app && flutter test` and keep widget/unit coverage high—no new code without tests. Commit `pubspec.lock` and analysis options so toolchains stay consistent.
-
-## Testing Guidelines
-Ruby specs run with `cd web && bundle exec rspec`, producing SimpleCov output in `coverage/`. Front-end behaviour is verified through Node’s test runner: `cd web && npm test` writes V8 coverage and JUnit XML under `reports/`.
-
-The ingestion layer is guarded by `pytest -q tests/test_mesh.py`; leave fixtures in `tests/` untouched so CI can replay them. New features should ship with matching specs and updated integration checks.
-
-## Commit & Pull Request Guidelines
-Commits should stay imperative and reference issues the way history does (`Add chat log entries... (#408)`). Squash noisy work-in-progress commits before pushing. Pull requests need a concise summary, screenshots or curl traces for UI/API tweaks, and links to tracked issues. Paste the command output for the test suites you ran and mention configuration toggles (`API_TOKEN`, `PRIVATE`) reviewers must set.
-
-## Security & Configuration Tips
-Never commit real API tokens or `.sqlite` dumps; use `.env.local` files ignored by Git. Confirm env defaults (`API_TOKEN`, `INSTANCE_DOMAIN`, `PRIVATE`) before deploying, and set `FEDERATION=0` when staging private nodes. Review `PROMETHEUS.md` when exposing metrics so scrape endpoints stay internal.

+## v0.6.0
+
+This is a service release of the radio mesh app-suite `potato-mesh` v0.6.0 which introduces new features and overhauls the user interface. The primary notable change is added support for multi-protocol along with an implementation of **Meshcore** in ingestor, web app, and frontend.
+
+Demo: <https://potatomesh.net/>
+
+### Meshcore
+
+To start ingesting Meshcore data to an upgraded potato-mesh web app, simply tell your ingestor to use the `PROTOCOL="meshcore"`.

+
+# Repository Guidelines
+
+Keep code as modular as possible to reduce duplication and improve reusability and readability — this applies to tests as well as production code. If a module grows large, split it into a submodule structure. Prefer composing small, single-purpose units over monolithic files.
+
+Make sure all tests pass for Python (`pytest`), Ruby (`rspec`), and JavaScript (`npm test`).
+
+All code must be 100% unit tested — every line, branch, and code path must have a unit test. "100%" is the floor, not the ceiling: smoke tests, integration tests, and end-to-end tests come on top of that. No new code ships without matching unit tests.
+
+All code must be 100% documented according to the language's API-doc standard (PDoc for Python, RDoc for Ruby, JSDoc for JavaScript, rustdoc for Rust, dartdoc for Dart). Documentation must be sufficient to generate complete API docs from source. In addition to API-level docs, add inline comments wherever the logic is not immediately self-evident.
+
+Every file in the repository must carry an Apache v2 license notice using the exact string `Copyright © 2025-26 l5yth & contributors`. **Source-code files** (`.rb`, `.py`, `.js`, `.rs`, `.dart`, etc.) must include the full Apache v2 license header block. **Non-source files** (docs, configs, YAML, TOML, Dockerfiles, etc.) must include a short 2-line Apache v2 notice (copyright line + license reference).
+
+Run linters for Python (`black`) and Ruby (`rufo`) to ensure consistent code formatting.
+
+## Project Structure & Module Organization
+The repository splits runtime and ingestion logic. `web/` holds the Sinatra dashboard (Ruby code in `lib/potato_mesh`, views in `views/`, static bundles in `public/`).
+
+`data/` hosts the Python Meshtastic ingestor plus migrations and CLI scripts. The ingestor is structured as the `data/mesh_ingestor/` package with the following key modules: `daemon.py` (main loop), `handlers.py` (packet processing), `interfaces.py` (interface helpers), `config.py` (env-driven config), `events.py` (TypedDict event schemas), `mesh_protocol.py` (MeshProtocol base), `node_identity.py` (canonical node ID utilities), `decode_payload.py` (CLI protobuf decoder), and the `protocols/` subpackage (currently `meshtastic.py`). API contracts for all POST ingest routes are documented in `data/mesh_ingestor/CONTRACTS.md`. API fixtures and end-to-end harnesses live in `tests/`. Dockerfiles and compose files support containerized workflows.
+
+`matrix/` contains the Rust Matrix bridge; build with `cargo build --release` or `docker build -f matrix/Dockerfile .`, and keep bridge config under `matrix/Config.toml` when running locally.
+
+## Build, Test, and Development Commands
+Run dependency installs inside `web/`: `bundle install` for gems and `npm ci` for JavaScript tooling. Start the app with `cd web && API_TOKEN=dev ./app.sh` for local work or `bundle exec rackup -p 41447` when integrating elsewhere.
+
+Prep ingestion with `python -m venv .venv && pip install -r data/requirements.txt`; `./data/mesh.sh` streams from live radios. `docker-compose -f docker-compose.dev.yml up` brings up the full stack.
+
+Container images publish via `.github/workflows/docker.yml` as `potato-mesh-{service}-linux-$arch` (`web`, `ingestor`, `matrix-bridge`), using the Dockerfiles in `web/`, `data/`, and `matrix/`.
+
+## Coding Style & Naming Conventions
+Use two-space indentation for Ruby and keep `# frozen_string_literal: true` at the top of new files. Keep Ruby classes/modules in `CamelCase`, filenames in `snake_case.rb`, and feature specs in `*_spec.rb`.
+
+JavaScript follows ES modules under `public/assets/js`; co-locate components with `__tests__` folders and use kebab-case filenames. Format Ruby via `bundle exec rufo .` and Python via `black`. Skip committing generated coverage artifacts.
+
+## Flutter Mobile App (`app/`)
+The Flutter client lives in `app/`. Keep only the mobile targets (`android/`, `ios/`) under version control unless you explicitly support other platforms. Do not commit Flutter build outputs or editor cruft (`.dart_tool/`, `.flutter-plugins-dependencies`, `.idea/`, `.metadata`, `*.iml`, `.fvmrc` if unused).
+
+Install dependencies with `cd app && flutter pub get`; format with `dart format .` and lint via `flutter analyze`. Run tests with `cd app && flutter test` and keep widget/unit coverage high—no new code without tests. Commit `pubspec.lock` and analysis options so toolchains stay consistent.
+
+## Testing Guidelines
+Ruby specs run with `cd web && bundle exec rspec`, producing SimpleCov output in `coverage/`. Front-end behaviour is verified through Node’s test runner: `cd web && npm test` writes V8 coverage and JUnit XML under `reports/`.
+
+The ingestion layer is tested with `pytest -q tests/`; leave fixtures in `tests/` untouched so CI can replay them. The suite includes both integration tests (`test_mesh.py`) and focused unit tests — `test_events_unit.py` (TypedDict schemas), `test_provider_unit.py` (Provider protocol conformance and `MeshtasticProvider`), `test_node_identity_unit.py` (canonical ID helpers), `test_daemon_unit.py`, `test_serialization_unit.py`, and `test_decode_payload.py`. New features should ship with matching specs and updated integration checks.
+
+## Adding a New Ingestor Protocol
+The `data/mesh_ingestor/mesh_protocol.py` module defines a `@runtime_checkable` `MeshProtocol` class with five members: `name` (str), `subscribe()`, `connect(*, active_candidate)`, `extract_host_node_id(iface)`, and `node_snapshot_items(iface)`. To add a new backend (e.g. Reticulum):
+
+1. Create `data/mesh_ingestor/protocols/<name>.py` with a class satisfying the `MeshProtocol` interface.
+2. Register it in `data/mesh_ingestor/protocols/__init__.py`.
+3. Pass an instance via `daemon.main(provider=...)` or make it the default in `main()`.
+4. Cover the protocol with unit tests in `tests/test_provider_unit.py` — at minimum an `isinstance(..., MeshProtocol)` conformance check and any retry/error-handling paths.
+
+Consult `data/mesh_ingestor/CONTRACTS.md` for the canonical event shapes all protocols must emit.
+
+## GitHub Configuration Standards
+Every language used in the repository must have a Dependabot entry checking for dependency updates on a **weekly** schedule. Keep the Dependabot config up to date as new languages or package ecosystems are added.
+
+Codecov must be configured with a **100% coverage target** and a **10% threshold** (i.e. a drop of more than 10 percentage points fails the check). The `codecov.yml` should enforce this on both patch and project coverage.
+
+Every service/component must have at least one GitHub Actions workflow that **builds and runs tests on pull requests against `main` and on direct pushes to `main`**. Workflows should cover all relevant test suites (Python, Ruby, JS, Rust, Flutter) for the components they touch.
+
+## Commit & Pull Request Guidelines
+Commits should stay imperative and reference issues the way history does (`Add chat log entries... (#408)`). Squash noisy work-in-progress commits before pushing. Pull requests need a concise summary, screenshots or curl traces for UI/API tweaks, and links to tracked issues. Paste the command output for the test suites you ran and mention configuration toggles (`API_TOKEN`, `PRIVATE`) reviewers must set.
+
+## Security & Configuration Tips
+Never commit real API tokens or `.sqlite` dumps; use `.env.local` files ignored by Git. Confirm env defaults (`API_TOKEN`, `INSTANCE_DOMAIN`, `PRIVATE`) before deploying, and set `FEDERATION=0` when staging private nodes. Review `PROMETHEUS.md` when exposing metrics so scrape endpoints stay internal.

+`pages/` directory inside `web/`. Each `.md` file automatically becomes a nav
+entry and a route under `/pages/<slug>`.
+
+Files are named `<sort-prefix>-<slug>.md` — the numeric prefix controls
+navigation order and the slug becomes the URL path and nav label:

+## Mesh ingestor contracts (stable interfaces)
+
+This repo’s ingestion pipeline is split into:
+
+- **Python collector** (`data/mesh_ingestor/*`) which normalizes packets/events and POSTs JSON to the web app.
+- **Sinatra web app** (`web/`) which accepts those payloads on `POST /api/*` ingest routes and persists them into SQLite tables defined under `data/*.sql`.
+
+This document records the **contracts that future protocols must preserve**. The intent is to enable adding new protocols (MeshCore, Reticulum, …) without changing the Ruby/DB/UI read-side.
+
+### Canonical node identity
+
+- **Canonical node id**: `nodes.node_id` is a `TEXT` primary key and is treated as canonical across the system.
+- **Format**: `!%08x` (lowercase hex, 8 chars), for example `!abcdef01`.
+- **Normalization**:
+  - Python currently normalizes via `data/mesh_ingestor/serialization.py:_canonical_node_id`.
+  - Ruby normalizes via `web/lib/potato_mesh/application/data_processing.rb:canonical_node_parts`.
+- **Dual addressing**: Ruby routes and queries accept either a canonical `!xxxxxxxx` string or a numeric node id; they normalize to `node_id`.
+
+Note: non-Meshtastic protocols will need a strategy to map their native node identifiers into this `!%08x` space. That mapping is intentionally not standardized in code yet.
+
+### Ingest HTTP routes and payload shapes
+
+Future providers should emit payloads that match these shapes (keys + types), which are validated by existing tests (notably `tests/test_mesh.py`).
+
+#### `POST /api/nodes`
+
+Payload is a mapping keyed by canonical node id, with an optional top-level `”ingestor”` key:
+
+- `{ “!abcdef01”: { ... node fields ... }, “ingestor”: “!ingestornodeid” }`
+
+When `”ingestor”` is present the protocol is inherited from the registered ingestor (see `POST /api/ingestors`); omitting it defaults to `”meshtastic”`.
+
+Node entry fields are “Meshtastic-ish” (camelCase) and may include:
+
+- `num` (int node number)
+- `lastHeard` (int unix seconds)
+- `snr` (float)
+- `hopsAway` (int)
+- `isFavorite` (bool)
+- `user` (mapping; e.g. `shortName`, `longName`, `macaddr`, `hwModel`, `publicKey`, `isUnmessagable`)
+  - `role` (optional string) — omit when unknown; known values include Meshtastic role names (e.g. `CLIENT`, `ROUTER`) and MeshCore role names (`COMPANION`, `REPEATER`, `ROOM_SERVER`, `SENSOR`)
+- `deviceMetrics` (mapping; e.g. `batteryLevel`, `voltage`, `channelUtilization`, `airUtilTx`, `uptimeSeconds`)
+- `position` (mapping; `latitude`, `longitude`, `altitude`, `time`, `locationSource`, `precisionBits`, optional nested `raw`)
+- Optional radio metadata: `lora_freq`, `modem_preset`
+
+#### `POST /api/messages`
+
+Single message payload:
+
+- Required: `id` (int), `rx_time` (int), `rx_iso` (string)
+- Identity: `from_id` (string/int), `to_id` (string/int), `channel` (int), `portnum` (string|nil)
+- Payload: `text` (string|nil), `encrypted` (string|nil), `reply_id` (int|nil), `emoji` (string|nil)
+- RF: `snr` (float|nil), `rssi` (int|nil), `hop_limit` (int|nil)
+- Meta: `channel_name` (string; only when not encrypted and known), `ingestor` (canonical host id), `lora_freq`, `modem_preset`
+
+**Cross-ingestor deduplication.** The `id` field is the sole dedup key — the server collapses repeat POSTs on the `messages.id` PRIMARY KEY. Protocols that lack a firmware-assigned packet ID MUST derive a stable, sender-side fingerprint so that the same physical transmission heard by multiple ingestors produces the same `id`. The id MUST fit in 53 bits (`0 <= id <= (1 << 53) - 1`) to round-trip through the JavaScript frontend without precision loss.
+
+For MeshCore the canonical fingerprint is:
+
+```
+v1:<sender_identity>:<sender_timestamp>:<discriminator>:<text>
+```
+
+hashed with SHA-256 and truncated to 53 bits (first 7 bytes, masked). Components:
+
+- `sender_identity` — for channel messages, the lowercased+stripped sender name parsed from a leading `SenderName:` prefix in the message text (split on the first colon, surrounding whitespace stripped); for direct messages, the sender's `pubkey_prefix` from the MeshCore event payload. Empty string when unavailable — when the channel-message text lacks any `SenderName:` prefix the dedup degrades and two distinct senders sharing timestamp + channel + text collide. In practice MeshCore clients always prefix the name; the residual risk is anonymous/malformed transmissions.
+- `sender_timestamp` — Unix seconds from the sender's clock (identical across receivers).
+- `discriminator` — `c<N>` for channel messages on channel `N`, `dm` for direct messages.
+- `text` — the message text exactly as transmitted.
+
+The `v1:` prefix lets the format evolve (e.g. add a channel-secret hash) without colliding with previously-written ids.
+
+**Known limitations of the v1 fingerprint:**
+
+- *Format-string ambiguity around `:`.* Components are joined with literal colons and not length-prefixed, so a colon embedded in `sender_identity` or `text` shifts the boundary between fields. In theory two distinct triples (e.g. `sender_identity="a:b"` vs `sender_identity="a"` with a leading `b:` in `text`) can produce the same fingerprint. In practice this is vanishingly rare — MeshCore sender names rarely contain colons and even then both senders would have to land on the same timestamp/channel — but a `v2` revision should switch to a delimiter that cannot appear in any component (e.g. `\x00`) or length-prefix each field.
+- *meshcore_py text-decoding inconsistency.* The upstream `meshcore_py` reader strips trailing `\0` bytes on the real-time `CHANNEL_MSG_RECV` path but not on the sync-replay path. If the same physical message is heard once in real-time and once via sync-replay, the byte sequences differ → different fingerprints → duplicate row. Out of scope for the ingestor; track upstream.
+- *Sender-side clock reset.* MeshCore nodes without an RTC start `sender_timestamp` from `0` after reboot. Two messages from the same sender containing the same text within one second of power-on collapse into a single row. Acceptable trade-off given the alternative (no dedup at all).
+- *Relay-rewritten `sender_timestamp` (#756).* MeshCore has been observed delivering the same physical packet twice with a rewritten `sender_timestamp` (≈10 s later, same `from_id`/`channel`/`text`), which flips the v1 fingerprint and bypasses the `messages.id` PK collapse. To cover this, the web app runs an additional content-level dedup on insert: for `protocol = "meshcore"` with non-empty `text` and a known `from_id`, a second row matching `(from_id, to_id, channel, text)` within ±30 s of `rx_time` is dropped (window lives in `MESHCORE_CONTENT_DEDUP_WINDOW_SECONDS`). The window is ~3× the observed relay delta; legitimate rapid re-sends of identical short text (e.g. `hi`, `ack`, `ok`, `test`) from the same sender on the same channel **within 30 s** will be silently collapsed into one row. Ingestors MUST still produce deterministic v1 ids — this content-level layer is additive, not a replacement. Pre-existing duplicates are cleared once by a `PRAGMA user_version`-gated one-shot backfill on startup.
+- *Concurrent-insert race (#756).* The content-dedup SELECT and the downstream INSERT are not currently wrapped in a shared transaction, so two concurrent Puma threads carrying the same content with different ids can both pass the pre-check and both insert. Duplicates produced this way are narrow (single-node multi-threaded ingest) and are not cleaned up on subsequent boots because the backfill is one-shot. If the race is ever observed in production, tighten `insert_message` to wrap the meshcore pre-check + id-PK path in `db.transaction(:immediate)`.
+- *Upstream `meshcore` reader crash on truncated advertisements (#754).* `meshcore-py` 2.3.6 (latest at the time of writing) raises `IndexError` from `MessageReader.handle_rx` at `reader.py:365` when a `DEVICE_INFO`/advertisement frame declares `fw_ver >= 10` but omits the trailing `path_hash_mode` byte. Because the frame is parsed inside a detached `asyncio.create_task(...)`, the exception surfaces as `Task exception was never retrieved` on stderr and the event for that frame is lost. The ingestor installs a runtime patch (`data/mesh_ingestor/protocols/_meshcore_patches.py`) that wraps `handle_rx`, logs one line with the first 32 bytes of the offending frame under `context=meshcore.reader.patch`, and lets the task exit cleanly; a loop-level handler (`context=asyncio.unhandled`) catches anything the targeted patch misses. Both shims are additive and will be removed once upstream ships a defensive length check.

+### GET endpoint filtering
+
+All collection GET endpoints (`/api/nodes`, `/api/messages`, `/api/positions`, `/api/telemetry`, `/api/traces`, `/api/neighbors`, `/api/ingestors`) accept an optional `?protocol=<value>` query parameter. When present, only records whose `protocol` column matches the given value are returned. The `protocol` field is included in all GET responses.

+  Because the frame is parsed inside a detached

+  ``Task exception was never retrieved`` stderr dump and the decoded event
+  for that frame is lost.  See GitHub issue #754.

 For each PotatoMesh node, the bridge creates (or uses) a **Matrix puppet user**:

-### Docker Secrets
+### Secret Files

-Every env var above supports a `*_FILE` companion (for example, `MATRIX_AS_TOKEN_FILE`).
-When present, the bridge reads the file contents and uses them instead of the plain env var.
-If `POTATOMESH_SECRETS_DIR` is set (or container defaults are enabled), the bridge also
-checks for files named after the env vars (for example, `/run/secrets/MATRIX_AS_TOKEN`)
-even when the `*_FILE` variable is not set.
+If you supply `*_FILE` values, the bridge reads the secret contents and trims whitespace. When running inside a container, the bridge also checks the default secrets directory (default: `/run/secrets`) for:

-### Precedence
-
-From highest to lowest:
-
-1. `*_FILE` secret values (explicit or default secrets directory)
-2. Environment variables
-3. CLI flags
-4. TOML config
-5. Built-in defaults
+* `matrix_as_token`
+* `matrix_hs_token`

 ### Container Defaults

-When container defaults are enabled (auto-detected or forced):
+Container detection checks `POTATOMESH_CONTAINER`, `CONTAINER`, and `/proc/1/cgroup`. When detected (or forced with `--container`), defaults shift to:

- Default config path: `/app/Config.toml`
- Default state file: `/app/bridge_state.json`
- Default secrets directory: `/run/secrets`
- Default poll interval: 120 seconds
+* Config path: `/app/Config.toml`
+* State file: `/app/bridge_state.json`
+* Secrets dir: `/run/secrets`
+* Poll interval: 15 seconds (if not otherwise configured)

-Disable container defaults with `--no-container-defaults` or set
-`POTATOMESH_CONTAINER_DEFAULTS=0`.
+Set `POTATOMESH_CONTAINER=0` or `--no-container` to opt out of container defaults.
+
+### Docker Compose First Run
+
+Before starting Compose, complete this preflight checklist:
+
+1. Ensure `matrix/Config.toml` exists as a regular file on the host (not a directory).
+2. Fill required Matrix values in `matrix/Config.toml`:
+   - `matrix.as_token`
+   - `matrix.hs_token`
+   - `matrix.server_name`
+   - `matrix.room_id`
+   - `matrix.homeserver`
+
+This is required because the shared Compose anchor `x-matrix-bridge-base` mounts `./matrix/Config.toml` to `/app/Config.toml`.
+Then follow the token and namespace requirements in [Matrix Appservice Setup (Synapse example)](#matrix-appservice-setup-synapse-example).
+
+#### Troubleshooting
+
+| Symptom | Likely cause | What to check |
+| --- | --- | --- |
+| `Is a directory (os error 21)` | Host mount source became a directory | `matrix/Config.toml` was missing at mount time and got created as a directory on host. |
+| `M_UNKNOWN_TOKEN` / `401 Unauthorized` | Matrix appservice token mismatch | Verify `matrix.as_token` matches your appservice registration and setup in [Matrix Appservice Setup (Synapse example)](#matrix-appservice-setup-synapse-example). |
+
+#### Recovery from accidental `Config.toml` directory creation
+
+```bash
+# from repo root
+rm -rf matrix/Config.toml
+touch matrix/Config.toml
+# then edit matrix/Config.toml and set valid matrix.as_token, matrix.hs_token,
+# matrix.server_name, matrix.room_id, and matrix.homeserver before starting compose
+```

-For this bridge, only the `as_token` and `namespaces.users` actually matter. The bridge does not accept inbound events; it only uses the `as_token` to call the homeserver.
+This bridge listens for Synapse appservice callbacks on port `41448` so it can log inbound transaction payloads. It still only forwards messages one way (PotatoMesh → Matrix), so inbound Matrix events are acknowledged but not bridged. The `as_token` and `namespaces.users` entries remain required for outbound calls, and the `url` should point at the listener.

 In Synapse’s `homeserver.yaml`, add the registration file under `app_service_config_files`, restart, and invite a puppet user to your target room (or use room ID directly).

+The bridge validates inbound appservice callbacks by comparing the `access_token` query param to `hs_token` in `Config.toml`, so keep those values in sync.
