From 91ba17a71dc3d3f038111669f2b2a4bda466b898 Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Sun, 27 Sep 2026 16:43:47 +0100 Subject: [PATCH 01/87] test(matrix): exercise live gateway with separate client Matrix changes lacked a live exchange test, so mocked adapter tests could miss failures between Synapse, gateway setup, and model-visible context. Start disposable Synapse and a checkout-built Linux gateway through Testcontainers. Drive events with a separate matrix-nio account and a fake model under an isolated HERMES_HOME. Provision a Linux nio client with its own encrypted device store so later encrypted cases can also run from macOS hosts. Run the suite in a dedicated CI job through scripts/run_tests.sh. The plain-room test confirms both the reply and the inbound model context. --- .github/workflows/matrix-live.yml | 40 +++ pyproject.toml | 3 + tests/fakes/fake_llm_provider.py | 4 +-

exit Synapse changes the owner of /data to UID 991 when it generates its configuration. On a Linux runner, the host test process cannot append to the resulting homeserver.yaml. Store Synapse data in a Docker volume and edit the configuration from a one-shot container. The test runner can kill a timed-out file worker before pytest tears down its fixtures. Enable Testcontainers' Ryuk reaper, pin its image by digest, and start it before creating the volume. Label the Synapse volume with the session ID; Testcontainers labels its network and containers. Ryuk can then remove these resources when the worker exits. --- tests/integration/matrix_live/conftest.py | 80 ++++++++++++++--------- 1 file changed, 49 insertions(+), 31 deletions(-) diff --git a/tests/integration/matrix_live/conftest.py b/tests/integration/matrix_live/conftest.py index 0469a19bf2781..ea7a3515beb95 100644 --- a/tests/integration/matrix_live/conftest.py +++ b/tests/integration/matrix_live/conftest.py @@ -7,6 +7,7 @@ import subprocess import time import urllib.request +import uuid from collections.abc import Callable, Iterator from dataclasses import dataclass from pathlib import Path @@ -16,7 +17,8 @@ from docker import errors as docker_errors from nio import AsyncClient, LoginResponse, RegisterResponse, RoomCreateResponse from testcontainers.core import testcontainers_config -from testcontainers.core.container import DockerContainer +from testcontainers.core.container import DockerContainer, Reaper +from testcontainers.core.labels import LABEL_SESSION_ID, SESSION_ID from testcontainers.core.network import Network from tests.fakes.fake_llm_provider import FakeLLMServer, Text, write_hermes_home @@ -24,6 +26,7 @@ REPO_ROOT = Path(__file__).resolve().parents[3] SYNAPSE_IMAGE = "matrixdotorg/synapse:v1.158.0@sha256:5f868df1f5772907c6dbe973a9b69ab530a5d6bb317c011a3788f7ad78eb1292" +RYUK_IMAGE = "testcontainers/ryuk:0.8.1@sha256:bf3f74a47dee0acda89aba4b2fc9c7fdcf994a084db02a2d06566f07baae022e" @dataclass(frozen=True) @@ -79,7 +82,8 @@ def docker_engine(tmp_path_factory: pytest.TempPathFactory) -> Iterator[None]: (docker_config / "config.json").write_text("{}", encoding="utf-8") previous_config = os.environ.get("DOCKER_CONFIG") os.environ["DOCKER_CONFIG"] = str(docker_config) -

That build prepares SQLite, Chromium, Node and the UI even though the tests start only a gateway. The separate Linux observer also built a second Python environment at test setup time to obtain matrix-nio crypto. Build a small Debian image with the PM-pinned Python and the locked Matrix and test dependencies before copying the checkout source. The gateway and observer use the same prepared interpreter in separate containers, while the gateway still runs against an isolated home and the host fake model. Keep gateway logs in timeout failures so startup problems remain diagnosable. The plain-room test passed with a 1.545-second test body and 26.8 seconds for the complete test file. On this host, an uncached image build took 128.1 seconds and a cached rebuild took 4.67 seconds. --- tests/integration/matrix_live/Dockerfile | 34 +++++++++++++++++++++++ tests/integration/matrix_live/conftest.py | 26 ++++++++--------- 2 files changed, 46 insertions(+), 14 deletions(-) create mode 100644 tests/integration/matrix_live/Dockerfile diff --git a/tests/integration/matrix_live/Dockerfile b/tests/integration/matrix_live/Dockerfile new file mode 100644 index 0000000000000..46027b241fa61 --- /dev/null +++ b/tests/integration/matrix_live/Dockerfile @@ -0,0 +1,34 @@ +FROM debian:13.4@sha256:e2d08da6f42ef4b09b165d55528a12727aeed8240dc9edf888e3ec07e10ef9da + +ENV PYTHONUNBUFFERED=1 \ + PYTHONDONTWRITEBYTECODE=1 \ + HERMES_RUNTIME_DIR=/opt/hermes/tools \ + CC=gcc \ + CXX=g++ + +RUN apt-get -o Acquire::Retries=3 update && \ + apt-get -o Acquire::Retries=3 install -y --no-install-recommends \ + ca-certificates python3 python3-venv gcc g++ make cmake \ + python3-dev libffi-dev libolm-dev && \ + rm -rf /var/lib/apt/lists/* && \ + useradd -u 10000 -m -d /opt/data hermes + +WORKDIR /opt/hermes + +COPY pm/ pm/ +COPY hermes_constants.py hermes_constants.py +COPY hermes_cli/__init__.py hermes_cli/runtime_state.py hermes_cli/ +COPY scripts/bundles/payload.py scripts/bundles/payload.py +RUN python3 -c 'from pm import ensure; [ensure(name, explicit=True) for name in ("uv", "python")]' && \ + python3 -c 'from pathlib import Path; from pm import installed_package; Path("/usr/local/bin/python3").symlink_to(installed_package("python").binary)' + +COPY pyproject.toml uv.lock ./ +RUN touch README.md && \ + python3 -m pm.build_env --source /opt/hermes --python /usr/local/bin/python3 \ + --out /opt/hermes/.venv --no-install-project --sealed \ + --extra matrix --group test && \ + /opt/hermes/.venv/bin/python -c 'import olm; import mautrix.crypto; import nio' + +COPY . . + +ENV HERMES_HOME=/opt/data diff --git a/tests/integration/matrix_live/conftest.py b/tests/integration/matrix_live/conftest.py index b4d4dc02920e7..8984d17790f2d 100644 --- a/tests/integration/matrix_live/conftest.py +++ b/tests/integration/matrix_live/conftest.py @@ -61,19 +61,23 @@ class LinuxNioObserver: account: MatrixAccount def run_python(self, code: str) -> str: - result = self.container.exec(["/opt/matrix-observer-env/bin/python", "-c", code]) + result = self.container.exec(["/opt/hermes/.venv/bin/python", "-c", code]) output = result.output.decode(errors="replace") assert result.exit_code == 0, f"Linux matrix-nio client failed:\n{output}" return output -def _wait_for(predicate: Callable[[], bool], description: str, *, timeout: float = 60.0) -> None: +def _wait_for( + predicate: Callable[[], bool], description: str, *, timeout: float = 60.0, + details: Callable[[], str] | None = None, +) -> None: deadline = time.monotonic() + timeout while time.monotonic() < deadline: if predicate(): return time.sleep(0.25) - pytest.fail(f"Timed out waiting for {description}") + suffix = f"\n{details()}" if details is not None else "" + pytest.fail(f"Timed out waiting for {description}{suffix}") @pytest.fixture(scope="module") @@ -114,6 +118,7 @@ def gateway_image(docker_engine: None) -> Iterator[str]: result = subprocess.run( [ "docker", "buildx", "build", "--load", "--progress=plain", + "-f", str(REPO_ROOT / "tests" / "integration" / "matrix_live" / "Dockerfile"), "--label", f"{LABEL_SESSION_ID}={SESSION_ID}", "-t", image, str(REPO_ROOT), ], capture_output=True, @@ -238,16 +243,6 @@ def linux_nio_observer( ).with_env("NIO_ACCESS_TOKEN", live_room.observer.access_token).with_env( "NIO_STORE_PATH", "/opt/data/matrix-nio-store" ) as container: - result = container.exec([ - "python3", "-m", "pm.build_env", "--source", "/opt/hermes", - "--python", "/usr/local/bin/python3", "--out", "/opt/matrix-observer-env", - "--group", "test", "--no-install-project", - ]) - assert result.exit_code == 0, ( - "Linux matrix-nio[e2e] environment could not be built from uv.lock:\n" - + result.output.decode(errors="replace")[-6000:] - ) - observer = LinuxNioObserver(container, live_room.observer) observer.run_python( "from client import open_encrypted_client; " @@ -302,5 +297,8 @@ def connected() -> bool: pytest.fail(f"Gateway exited before Matrix connected:\n{output}") return False - _wait_for(connected, "Matrix gateway initial sync", timeout=120) + _wait_for( + connected, "Matrix gateway initial sync", timeout=120, + details=lambda: container.get_wrapped_container().logs().decode(errors="replace")[-6000:], + ) yield LiveGateway(container, model) From 284b4da88aaf7c796114317cffebfb0512322e34 Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Sun, 27 Sep 2026 18:56:26 +0100 Subject: [PATCH 06/87] test(matrix): bound plain exchange wait The live plain-room test requested a one-second Synapse poll and allowed a minute before reporting a missing reply.

The fixture replaced DOCKER_CONFIG with an empty configuration to keep registry credentials away from the tests. That also discarded currentContext and the context metadata, so the Docker SDK, Testcontainers and the docker CLI all fell back to /var/run/docker.sock. scripts/run_tests.sh removed DOCKER_HOST, DOCKER_CONTEXT and DOCKER_CONFIG from the test environment, so a user could not select the socket explicitly either. The fixture now resolves the endpoint the same way the docker CLI does (DOCKER_HOST, then DOCKER_CONTEXT, then currentContext) before it isolates the configuration. It exports the result as DOCKER_HOST and removes DOCKER_CONTEXT, so the SDK probe, Testcontainers and the buildx build all connect to that endpoint. The isolated configuration keeps the CLI plugin directories, because Docker Desktop and Homebrew install buildx outside the default search path. It still contains no registry credentials or credential helpers. On macOS the daemon runs in a Linux VM and resolves bind-mount sources there. Testcontainers mounts the client-side socket path into Ryuk by default, which fails when that path is a host socket such as a context's. The fixture therefore mounts /var/run/docker.sock, the socket inside the VM, into Ryuk on macOS. The runner forwards DOCKER_HOST, DOCKER_CONTEXT and DOCKER_CONFIG. It still drops DOCKER_AUTH_CONFIG, DOCKER_CERT_PATH and DOCKER_TLS_VERIFY. With a scratch context whose socket forwards to OrbStack and counts connections, the plain exchange passed with 70 API connections through that socket. The previous fixture passed the same invocation with no connections through it, because it used /var/run/docker.sock instead. A context pointing at a missing socket now skips with a message that includes the socket path. --- scripts/run_tests.sh | 7 +- tests/integration/matrix_live/conftest.py | 77 ++++++++---- .../matrix_live/test_docker_configuration.py | 113 ++++++++++++++++++ tests/scripts/test_run_tests_shell.py | 30 +++++ 4 files changed, 202 insertions(+), 25 deletions(-) create mode 100644 tests/integration/matrix_live/test_docker_configuration.py diff --git a/scripts/run_tests.sh b/scripts/run_tests.sh index 0e73010e653f7..297c8248c4c5c 100755 --- a/scripts/run_tests.sh +++ b/scripts/run_tests.sh @@ -151,6 +151,11 @@ _pf86="$(env | sed -n 's/^ProgramFiles(x86)=//p' | head -n1)" # SSL_CERT_FILE/DIR are trust-store locations: the pinned interpreter's # OpenSSL has no compiled-in bundle path on NixOS, so network tests (PM # downloads, channel reads) need the host's pointer to verify TLS. +# DOCKER_HOST, DOCKER_CONTEXT and DOCKER_CONFIG select the Docker daemon as +# they do for the docker CLI, so Testcontainers suites can reach a daemon that +# is available only through a CLI context.

2026 19:12:54 +0100 Subject: [PATCH 09/87] test(matrix): drop the gateway image's crypto probe container The last dependency step of the test Dockerfile imports olm, mautrix.crypto and nio, so an image without Matrix crypto support already fails to build, and the fixture reports the build log. The fixture then started a container from the finished image only to run the same imports again. That check could not fail, and it added a container start to every test module. --- tests/integration/matrix_live/conftest.py | 9 --------- 1 file changed, 9 deletions(-) diff --git a/tests/integration/matrix_live/conftest.py b/tests/integration/matrix_live/conftest.py index 40bdc1b17be6d..aec59e47d532c 100644 --- a/tests/integration/matrix_live/conftest.py +++ b/tests/integration/matrix_live/conftest.py @@ -155,15 +155,6 @@ def gateway_image(docker_engine: None) -> Iterator[str]: timeout=1800, ) assert result.returncode == 0, f"Linux gateway image build failed:\n{result.stdout[-6000:]}\n{result.stderr[-6000:]}" - - with DockerContainer(image, entrypoint="/opt/hermes/.venv/bin/python").with_command( - ["-c", "import olm; import mautrix.crypto"] - ) as crypto_probe: - status = crypto_probe.get_wrapped_container().wait(timeout=30) - assert status["StatusCode"] == 0, ( - "Linux gateway image lacks Matrix crypto support:\n" - + crypto_probe.get_wrapped_container().logs().decode(errors="replace") - ) yield image finally: client = docker.from_env() From 651134bbadd2a056373215e2c568ad30125e1515 Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Tue, 29 Sep 2026 19:12:55 +0100 Subject: [PATCH 10/87] ci(matrix): build the live gateway image before the tests The gateway_image fixture built the Linux gateway image inside the pytest worker. run_tests_parallel.py kills a worker when the per-file timeout expires, so the cold build, the Synapse start-up and the exchange all had to fit in the 300-second per-file timeout that the workflow sets. The 45-minute job limit and the build's own 1800-second timeout could never take effect. A cold build of test_plain_exchange.py on OrbStack took 242 seconds of that budget. Move the build command to tests/integration/matrix_live/image_build.py. The fixture still uses it, so a local run builds a fresh image and removes it afterwards as before. The workflow runs the same module in a step before the tests and passes the tag in HERMES_TEST_MATRIX_IMAGE. When that variable is set, the fixture uses the image, checks that the daemon has it, and leaves it in place for the next test file. run_tests.sh forwards the variable, in the same way that it forwards HERMES_TEST_IMAGE for tests/docker. The build no longer has its own timeout: in the fixture the per-file timeout limits it, and in CI the job limit does. Drop the Buildx setup step. The fixture replaces DOCKER_CONFIG, where Buildx records the builder that the step creates, so every build used the daemon's default builder anyway. The pull_request path filter listed the production Dockerfile, which the live tests no longer use, and omitted most of the code that runs in the gateway. Filter on the code that the image copies and runs (the root modules, agent, cron, gateway, hermes_cli, hermes_platform, pm and tools), .dockerignore, the test runner and its setup action.

With rootful Docker on Linux, the directories that the gateway creates, such as logs/, belong to UID 10000 with mode 0755, so the runner's user cannot delete the files in them. run_tests_parallel.py ignores errors when it removes its temporary root, so each test left a tree under /var/tmp/hermes-pytest-/ that only root could remove. macOS was not affected, because OrbStack and Docker Desktop map bind-mount ownership to the host user. Run the gateway as the host UID and GID and keep the home's default mode. The image has no passwd entry for that UID, so set HOME to the home that the hermes user had. At teardown the fixture removes the home itself, so a file that the runner cannot delete fails the test instead of accumulating on the host. Windows has no host UID; Docker Desktop does not enforce ownership on bind mounts there, so the gateway keeps running as UID 10000. On OrbStack's Linux kernel, a home written by UID 10000 could not be removed by UID 501 ("Permission denied" on logs/gateway.log), and a home written as 501:20 could. The plain exchange passes as the host user on macOS. --- tests/integration/matrix_live/conftest.py | 22 ++++++++++++++++++---- 1 file changed, 18 insertions(+), 4 deletions(-) diff --git a/tests/integration/matrix_live/conftest.py b/tests/integration/matrix_live/conftest.py index 42326391a7e35..9234d502e4752 100644 --- a/tests/integration/matrix_live/conftest.py +++ b/tests/integration/matrix_live/conftest.py @@ -5,6 +5,7 @@ import asyncio import json import os +import shutil import subprocess import time import urllib.request @@ -291,6 +292,13 @@ def linux_nio_observer( yield observer +def _host_user() -> str: + """Return the container user that lets this user delete what a container writes to a bind mount.""" + if facts.os_family() == "windows": + return "10000:10000" + return f"{os.getuid()}:{os.getgid()}" + + @pytest.fixture def gateway( tmp_path: Path, @@ -301,7 +309,7 @@ def gateway( _, _, network = synapse room_id = live_room.room_id home = tmp_path / "hermes" - home.mkdir(mode=0o777) + home.mkdir() with FakeLLMServer([Text("Matrix live reply")], bind_host="0.0.0.0") as model: write_hermes_home( home, @@ -316,16 +324,17 @@ def gateway( f"MATRIX_HOME_ROOM={room_id}\n" "MATRIX_E2EE_MODE=optional\nMATRIX_REACTIONS=false\nMATRIX_AUTO_THREAD=false\n" ) - home.chmod(0o777) with DockerContainer( gateway_image, network=network, entrypoint="/opt/hermes/.venv/bin/python", - user="10000:10000", + user=_host_user(), working_dir="/opt/hermes", extra_hosts={"host.docker.internal": "host-gateway"}, - ).with_command("-m hermes_cli.main gateway run").with_volume_mapping(home, "/opt/data", "rw") as container: + ).with_command("-m hermes_cli.main gateway run").with_volume_mapping( + home, "/opt/data", "rw" + ).with_env("HOME", "/opt/data") as container: def connected() -> bool: output = container.get_wrapped_container().logs().decode(errors="replace") gateway_log = home / "logs" / "gateway.log" @@ -340,3 +349,8 @@ def connected() -> bool: details=lambda: container.get_wrapped_container().logs().decode(errors="replace")[-6000:], ) yield LiveGateway(container, model) + + # The test runner ignores errors when it deletes its temporary directory, so files that the + # container wrote and this user cannot delete would remain on the host.

A stray request would consume the scripted reply or appear in main_requests(), and the macOS firewall can ask whether to accept incoming connections. The gateway container reaches the fake as host.docker.internal. With a daemon on this host, as on Linux, the test network's bridge gateway is an address of this host, so the fake now listens on that address and host.docker.internal resolves to it. A daemon in a VM, such as Docker Desktop or OrbStack, does not expose that address on the host, and its host-gateway forwards to the host's loopback interface, so the fake listens on 127.0.0.1 there. The fixture chooses by trying to bind the gateway address. In OrbStack's Linux VM, a server bound to a network's gateway address answered a container on that network through the host.docker.internal mapping.

The Matrix adapter joins the invited room shortly after it connects, while the gateway is still in startup restore. During startup restore the gateway queues inbound messages and replays them when restore finishes, so a test's first message could reach the gateway through that replay. A scratch live test that sent its message as soon as the fixture yielded was queued in two of three runs. The replay can reach the adapter while the adapter's original dispatch of the same event still holds the session guard: for Matrix, the guard stays held during the typing-stop request after the handler has queued the event. The adapter then handles the replay as a second message while the session is busy, and the bot's first reply is the "Interrupting current task" notice. One native run of the oversized-media test failed this way. The gateway logs "Press Ctrl+C to stop" after startup restore has finished. The fixture now waits for that line as well as for the join, so a test's first message is dispatched directly. With this check the same scratch test was dispatched directly in three of three runs. When a test that uses the fixture fails, a report hook adds the last 200 lines of the gateway log to the failure report.

The Windows branch therefore never ran, and on a Windows host with Docker the gateway fixture called os.getuid(), which Windows does not have. Compare with "win32", as the conftest already does with "darwin". The matrix-live workflow's path filter omitted code that the gateway image copies and loads at run time: providers/, which agent/ imports; plugins/ outside the Matrix adapter (the plugin loader, model providers, memory and context engines); locales/, which agent/i18n.py reads; tui_gateway/, which gateway/ imports; and skills/, which the gateway syncs into its home at start-up. A change to any of them could break the live tests without running the workflow. Add all five. Rename HERMES_TEST_MATRIX_IMAGE to HERMES_TEST_MATRIX_GATEWAY_IMAGE. The suite uses Synapse, Ryuk and gateway images, and "Matrix image" reads most naturally as the homeserver. --- .github/workflows/matrix-live.yml | 10 +++++++--- scripts/run_tests.sh | 6 +++--- tests/integration/matrix_live/conftest.py | 4 ++-- tests/integration/matrix_live/image_build.py | 8 ++++---- tests/scripts/test_run_tests_shell.py | 4 ++-- 5 files changed, 18 insertions(+), 14 deletions(-) diff --git a/.github/workflows/matrix-live.yml b/.github/workflows/matrix-live.yml index e68dbc2aa027b..a96ca28cf4f99 100644 --- a/.github/workflows/matrix-live.yml +++ b/.github/workflows/matrix-live.yml @@ -12,17 +12,21 @@ on: - 'gateway/**' - 'hermes_cli/**' - 'hermes_platform/**' - - 'plugins/platforms/matrix/**' + - 'locales/**' + - 'plugins/**' - 'pm/**' + - 'providers/**' - 'scripts/bundles/payload.py' - 'scripts/ci/list_os_marked_tests.py' - 'scripts/ci/setup_toolchain.py' - 'scripts/run_tests.sh' - 'scripts/run_tests_parallel.py' + - 'skills/**' - 'tests/conftest.py' - 'tests/fakes/fake_llm_provider.py' - 'tests/integration/matrix_live/**' - 'tools/**' + - 'tui_gateway/**' - 'pyproject.toml' - 'uv.lock' push: @@ -38,7 +42,7 @@ jobs: runs-on: ubuntu-latest-32-core timeout-minutes: 45 env: - HERMES_TEST_MATRIX_IMAGE: hermes-matrix-live:ci + HERMES_TEST_MATRIX_GATEWAY_IMAGE: hermes-matrix-live:ci steps: - uses: actions/checkout@de0fac2e4500dabe0009e67214ff5f5447ce83dd # v6.0.2 - name: Set up locked Python and Matrix dependencies @@ -48,7 +52,7 @@ jobs: test-environment: 'true' # Build here so that the per-file test timeout does not have to cover a cold image build. - name: Build the Linux gateway image - run: '"$HERMES_PYTHON" -m tests.integration.matrix_live.image_build "$HERMES_TEST_MATRIX_IMAGE"' + run: '"$HERMES_PYTHON" -m tests.integration.matrix_live.image_build "$HERMES_TEST_MATRIX_GATEWAY_IMAGE"' - name: Run Matrix live client tests run: scripts/run_tests.sh --include-integration tests/integration/matrix_live/ env: diff --git a/scripts/run_tests.sh b/scripts/run_tests.sh index bc2e3ade2a8f9..531456607cb56 100755 --- a/scripts/run_tests.sh +++ b/scripts/run_tests.sh @@ -134,8 +134,8 @@ _pf86="$(env | sed -n 's/^ProgramFiles(x86)=//p' | head -n1)" # subprocess rebuild the 5GB image from a cold builder cache instead # (~4 min per worker per run, and the rebuilt image lacked the # HERMES_GIT_SHA build-arg the workflow bakes in). -# * HERMES_TEST_MATRIX_IMAGE specifies a prebuilt Linux gateway image for -# tests/integration/matrix_live, so its fixture skips the build. +# * HERMES_TEST_MATRIX_GATEWAY_IMAGE specifies a prebuilt Linux gateway +# image for tests/integration/matrix_live, so its fixture skips the build. # matrix-live.yml builds the image before the tests, so the build does not # count towards the per-file timeout. # * HERMES_E2E_REQUIRE_TUI turns a missing Ink TUI build into a failure in @@ -163,7 +163,7 @@ _pf86="$(env | sed -n 's/^ProgramFiles(x86)=//p' | head -n1)" # Keep this an explicit allowlist (no HERMES_TEST_* glob) so the "no # credential can leak" property stays auditable at a glance.

The previous member-count shortcut classified a bot-only room as a DM, and an m.direct entry classified larger or unreadable rooms as DMs. Those rooms could bypass both gates. Classify a room as a private bot chat only when the bot and exactly one other user are joined. Request JOIN membership explicitly: mautrix's state store includes invited users by default. The state store may also contain only a subset of a room's members, so use its joined IDs only when has_full_member_list confirms completeness. Otherwise query the homeserver with get_joined_members and apply room rules if that fails. Keep m.direct as room identity metadata, without using it for authorisation. Document the resulting allowlist and mention policy. Tests reproduced the bot-only, bot-absent, multi-user, invited-user, partial-cache and unknown-membership cases before their fixes. --- plugins/platforms/matrix/adapter.py | 56 ++++---- tests/gateway/test_matrix.py | 135 +++++++++++++++++++- website/docs/user-guide/messaging/matrix.md | 12 +- 3 files changed, 166 insertions(+), 37 deletions(-) diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index 9aac259a870a1..6eb76a3335e92 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -14,13 +14,12 @@ MATRIX_MAX_MEDIA_BYTES, MATRIX_ROOM_IDENTITY_TTL_SECONDS; MATRIX_APPROVAL_REQUIRE_SENDER (default true), MATRIX_APPROVAL_TIMEOUT_SECONDS (default 300). -Note: any room with <=2 joined members is auto-classified as a DM (see -``_resolve_room_identity``), regardless of ``m.direct`` account data or an explicit room name — -clients auto-name DMs like "Alice & Bot", so name alone can't be trusted.

After a password login the adapter now replaces the configured MATRIX_USER_ID with the homeserver's spelling of it, so the DM check matches the room's member list. That replacement also changed the store key. A deployment with a password login, MATRIX_USER_ID differing in case from the registered user, and a stable MATRIX_DEVICE_ID would open an empty store after upgrading. It would create a new Olm account for its existing device and could no longer decrypt history. The same happened on an in-process reconnect, because the second login read the replaced ID. Keep the configured ID in its own attribute and use it for the login identifier and, after a password login, for the store key, as before.

Room notes were consumed while the adapter built an event. The gateway could reject that event for sender policy or intercept it for a paused session, leaving no note for the next model turn. A queued follow-up also bypasses normal admission and missed the note entirely. Consume notes in inbound model-message preparation, which both cold and queued turns use after their dispatch gates. Rejected and intercepted messages therefore leave pending notes for the next turn. Busy-session debounce and pending-message merges also discarded channel context from later events. Append it during both merges so accepted context reaches the model. Request joined member profiles explicitly so invited users do not appear in unnamed room titles. Runner admission, paused and queued turns, busy merges, room bounds, coalescing and invited membership have focused regressions. --- gateway/platforms/base.py | 9 +- gateway/platforms/event.py | 5 +

prompts A Matrix state update can change a member-derived room title, an explicit room name or the room topic between turns. Those changes altered the session-context prompt and agent cache signature, which rebuilt the agent and invalidated the provider's cached prefix. Render the Matrix room name, topic and same-sender display name from the session's persisted origin. Keep live state for routing and room identity. Member changes join the existing per-turn room notes, which also report explicit name and topic edits. A regression reproduced prompt and signature drift on the previous head. It now verifies stable bytes and signatures after a member rename, a join, an explicit room rename and a topic edit. --- gateway/session.py | 7 ++ plugins/platforms/matrix/room_context.py | 16 +++++

00:00:00 2001 From: Iain Lane Date: Sun, 27 Sep 2026 17:50:41 +0100 Subject: [PATCH 25/87] fix(matrix): refresh room origin on reset and fan out state notes Matrix conversations pin room metadata in their initial prompt. A reset copied the previous origin, so a new conversation still used an old room name or topic after a state change. Pass the live Matrix source through explicit and automatic resets, validate its route, and persist it as the fresh session origin. Room state notes were consumed once per room. In rooms with several threads, the first model turn received a change and the others kept old prompt metadata without an update. Track delivery per session and filter notes recorded before a new session began. Keep the room and session cursor stores bounded. Regressions cover stable old prompts, fresh reset prompts after a restart, two existing threads, and a thread created after the update. Remove two unused runner fixture attributes. The current runner contract does not declare these attributes, and its facade and mixins do not read them. --- gateway/run_inbound.py | 8 ++++- gateway/run_turn.py | 2 +- gateway/session.py | 29 ++++++++++++--- gateway/slash_commands_session.py | 2 +- plugins/platforms/matrix/adapter.py | 8 +++-- plugins/platforms/matrix/room_context.py | 44 ++++++++++++++++++----- tests/gateway/test_matrix.py | 45 ++++++++++++++++++++---- tests/gateway/test_session.py | 40 +++++++++++++++++++-- 8 files changed, 152 insertions(+), 26 deletions(-) diff --git a/gateway/run_inbound.py b/gateway/run_inbound.py index 1d3f3c1064dca..50c876e805084 100644 --- a/gateway/run_inbound.py +++ b/gateway/run_inbound.py @@ -17,6 +17,7 @@ import re import time from contextlib import suppress +from datetime import datetime from pathlib import Path from agent.i18n import t @@ -1741,7 +1742,12 @@ async def _prepare_inbound_message_text( adapter = self._intake_adapter_for(source) take_channel_context = getattr(type(adapter), "take_turn_channel_context", None) if callable(take_channel_context): - context = take_channel_context(adapter, event) + entry = getattr(getattr(self, "session_store", None), "_entries", {}).get(session_key) + created_at = getattr(entry, "created_at", None) + context = take_channel_context( + adapter, event, session_key, + created_at if isinstance(created_at, datetime) else None, + ) if context: message_text = f"{context}\n\n[New message]\n{message_text}" return message_text diff --git a/gateway/run_turn.py b/gateway/run_turn.py index 698e59e0034bd..5ed021b2d5ff5 100644 --- a/gateway/run_turn.py +++ b/gateway/run_turn.py @@ -1775,7 +1775,7 @@ async def _hmwa_compression_exhaustion_reset( ) elif agent_result.get("compression_exhausted") and session_entry and session_key: logger.info("Auto-resetting session %s after compression exhaustion.", session_entry.session_id) - new_entry = await self.async_session_store.reset_session(session_key) + new_entry = await self.async_session_store.reset_session(session_key, source=source) self._evict_cached_agent(session_key) # Conversation boundary: the funnel clears every conversation-scoped per-session dict. self._clear_conversation_scope(session_key, reason="compression_exhausted_reset") diff --git a/gateway/session.py b/gateway/session.py index ca3424c460684..d458c23d577d4 100644 --- a/gateway/session.py +++ b/gateway/session.py @@ -1132,36 +1132,55 @@ def get_model_override(self, session_key: str) -> Optional[dict[str, str]]: entry = self._entry_locked(session_key) return dict(entry.model_override) if entry and entry.model_override else None - def reset_session(self, session_key: str, display_name: Optional[str] = None) -> Optional[SessionEntry]: + def reset_session( + self, session_key: str, display_name: Optional[str] = None, + *, source: Optional[SessionSource] = None, + ) -> Optional[SessionEntry]: """Force reset a session, creating a new session ID.""" with self._lock: old_entry = self._entry_locked(session_key) if old_entry is None: return None + origin = old_entry.origin + if source is not None and source.platform == Platform.MATRIX: + if self._generate_session_key(source) != session_key: + raise ValueError("Matrix reset source does not match the session key") + if origin is not None and ( + source.platform, source.chat_id, source.thread_id, source.profile + ) != ( + origin.platform, origin.chat_id, origin.thread_id, origin.profile + ): + raise ValueError("Matrix reset source does not match the session origin") + origin = source now = _now() session_id = _new_session_id(now) new_entry = self._replace_route_locked( session_key, old_entry, session_id, now, + origin=origin, display_name=display_name if display_name is not None else old_entry.display_name, is_fresh_reset=True, ) db_create_kwargs = self._session_create_kwargs( - session_id=session_id, session_key=session_key, origin=old_entry.origin, + session_id=session_id, session_key=session_key, origin=origin, source_value=old_entry.platform.value if old_entry.platform else "unknown", display_name=old_entry.display_name, parent_session_id=old_entry.session_id, ) self._finish_route_transition( session_key, end_session_id=old_entry.session_id, end_reason="session_reset", - create_kwargs=db_create_kwargs, origin=old_entry.origin, + create_kwargs=db_create_kwargs, origin=origin, display_name=new_entry.display_name, during=" during reset", ) return new_entry - def _replace_route_locked(self, session_key, old_entry, session_id, now, **fields) -> SessionEntry: + def _replace_route_locked( + self, session_key, old_entry, session_id, now, + *, origin: Optional[SessionSource] = None, **fields, + ) -> SessionEntry: """Publish a fresh entry (inheriting origin/platform/chat_type) and save.

Room state notes, however, lived only in adapter memory. A rename, topic edit or member change while the gateway was offline left a restored conversation with old metadata and no correction. Persist the room state last delivered to each Matrix session. On the next prepared model turn, compare that state with the current room identity and add bounded correction notes to the user message. Merge live state-event notes by kind so the same change appears once. Hash joined members and display names to detect membership changes without storing their list in session metadata. A real SessionStore restart regression covers two conversations in one room, stable prompt bytes and one correction per conversation. A second restart confirms that delivered corrections stay consumed. Remove the same unused runner attributes from the generic fixtures introduced by this contribution. The runner contract does not declare these fields, and its facade and mixins do not read them. --- gateway/run_inbound.py | 29 ++++++-- gateway/session.py | 3 +- plugins/platforms/matrix/adapter.py | 30 ++++++-- plugins/platforms/matrix/room_context.py | 87 ++++++++++++++++++++---- tests/gateway/test_matrix.py | 66 ++++++++++++++++++ 5 files changed, 190 insertions(+), 25 deletions(-) diff --git a/gateway/run_inbound.py b/gateway/run_inbound.py index 50c876e805084..f0247bf4fba9f 100644 --- a/gateway/run_inbound.py +++ b/gateway/run_inbound.py @@ -33,7 +33,7 @@ unauthorized_owner_hint, ) from gateway.session import ( -

Resolving the current identity from the owning adapter makes the correction and the recorded state describe the same room snapshot. Current state replaces stale queued notes for name, topic and membership changes. Room-state acknowledgement was written during message preparation. If the gateway stopped before the user transcript row was saved, a restored session suppressed a correction that the model never saw. Record the state on the user row instead. A failed preparation leaves no acknowledgement; successful and failed agent turns use their existing transcript persistence paths. Regressions exercise a stale queued message and a crash before the transcript write with a real SessionStore restart. Remove the same unused runner attributes from the generic fixtures introduced by this contribution. The runner contract does not declare these fields, and its facade and mixins do not read them. --- gateway/run_inbound.py | 24 ++-- gateway/run_turn.py | 12 +- plugins/platforms/matrix/adapter.py | 10

18:45:22 +0100 Subject: [PATCH 28/87] fix(matrix): keep one history backfill when text batches merge An earlier commit in this series appended every incoming event's channel_context when the base adapter merged a text batch, a pending message or a busy-session debounce. Matrix room notes were the reason, but Matrix now attaches its notes when the turn is prepared, so the change only affected Discord, Slack and relay. Discord backfills a thread message by scanning back to the bot's last reply. For two batched messages, the second backfill already contains the first backfill and the first message, so the merged turn showed the first backfill twice and the first message three times. Restore the previous merge, which keeps the first event's context, and add a Discord test for two batched thread messages. --- gateway/platforms/base.py | 4 -- .../gateway/test_active_session_text_merge.py | 41 ------------------- tests/gateway/test_discord_free_response.py | 24 +++++++++++ 3 files changed, 24 insertions(+), 45 deletions(-) diff --git a/gateway/platforms/base.py b/gateway/platforms/base.py index 4bdf8e77668ac..4466b5a1ad234 100644 --- a/gateway/platforms/base.py +++ b/gateway/platforms/base.py @@ -1829,7 +1829,6 @@ def _padded_inline_flags(msg: MessageEvent) -> list[Optional[bool]]: existing.media_text_inlined.extend(incoming_inline_flags) if event.text: existing.text = BasePlatformAdapter._merge_caption(existing.text, event.text) -

Plugins must use a generic surface instead. The Matrix adapter also kept a second mechanism: notes stashed from live state events with per-session cursors. On the production path the runner discarded those notes in favour of the snapshot comparison, so only tests reached them. Add BasePlatformAdapter.prepare_turn_context. The gateway calls it while it prepares a turn, passing the session origin and the channel_state saved with the latest user row. The adapter returns a TurnContextUpdate with a note for the user message and a new snapshot. The snapshot travels on MessageEvent.channel_state and is saved in the user row's display_metadata, so a change is acknowledged only when the turn that reported it is saved. An adapter that sets reports_chat_changes_in_turn keeps the session origin's chat name, topic and user name in the session-context prompt, which stays byte-stable while the notes report later changes. Matrix implements the hook with its existing snapshot comparison. The live-note stash, its take methods and their tests are gone; the remaining tests run through a real SessionStore. The state handlers now only invalidate the cached room identity. build_session_context no longer pins anything, so tools read the current chat name through HERMES_SESSION_CHAT_NAME, and the prompt copy uses session_identity.replace_source. reset_session refreshes the origin's name, topic and user name from the /reset source for every platform and keeps the origin's routing fields, which removes the Matrix guard that could raise after /reset had already evicted the agent. format_untrusted_prompt_value becomes public because the plugin uses it. Assert that the queued channel state and reset result exist before the original assertions access their fields. Keep every original assertion and parameter row. The consolidated runner fixture also drops the two unused attributes. --- gateway/platforms/base.py | 18 +- gateway/platforms/event.py | 19 +- gateway/run_agent_cache.py | 14 +- gateway/run_inbound.py | 43 +- gateway/run_inbound_turn_context.py | 57 ++ gateway/run_turn.py | 30 +- gateway/session.py | 54 +- plugins/platforms/matrix/adapter.py | 57 +- plugins/platforms/matrix/room_context.py | 200 +------ tests/gateway/test_matrix.py | 663 +++++++---------------- tests/gateway/test_session.py | 60 +- 11 files changed, 423 insertions(+), 792 deletions(-) create mode 100644 gateway/run_inbound_turn_context.py diff --git a/gateway/platforms/base.py b/gateway/platforms/base.py index 4466b5a1ad234..e6455e4c8e871 100644 --- a/gateway/platforms/base.py +++ b/gateway/platforms/base.py @@ -428,7 +428,7 @@ def is_host_excluded_by_no_proxy(hostname: str, no_proxy_value: str | None = Non from gateway.platforms.base_exec_approval import ( approval_timeout_seconds, ea_action_labels, ea_default_reason_text, ea_header_text, ea_reason_label_text, ea_smart_deny_line_text, format_approval_deadline_line) -from gateway.platforms.event import MessageEvent, MessageType, ProcessingOutcome +from gateway.platforms.event import MessageEvent, MessageType, ProcessingOutcome, TurnContextUpdate from gateway.warning_notifications import diagnostic_wake_muted from hermes_cli.observability.shared_metrics_gateway import records_delivery, stop_reply_clock from gateway.session import SessionSource, build_session_key @@ -1959,6 +1959,10 @@ def set_status_text(self, chat_id: str, text: Optional[str]) -> None: # ``hermes gateway migrate`` can tell "URL changes" from "this profile would be skipped" as new # HTTP-inbound adapters gain the prefix. serves_profile_prefix: bool = False + # ``prepare_turn_context`` reports chat name and topic changes in the user message.

""" From 56f1a5de95d537cc7e9f1dafeb712e294d858c1c Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Tue, 29 Sep 2026 19:15:47 +0100 Subject: [PATCH 30/87] fix(matrix): keep the room baseline when state reads fail The room identity read m.room.name, m.room.topic and m.room.canonical_alias one after another and treated any exception as "the room has no such state". A timeout, a 5xx or a rate-limit response therefore looked like a cleared name and topic. The next turn told the model that the room name was now its room ID and that the topic was cleared, and saved that snapshot as the acknowledged baseline. The following successful read then produced a second pair of notes that restored the real values. The turn hook also forced a fresh read on every text message, so each reply waited for three sequential, unbounded homeserver requests. Only M_NOT_FOUND now means absent state. The identity reads the three state events and the member list concurrently, and each request stops after _ROOM_STATE_READ_TIMEOUT_SECONDS. When any read fails the identity has no room_state snapshot, and prepare_turn_context returns None: the turn gets no note and saves no channel_state, so the last saved snapshot stays the baseline. The hook reuses the cached identity that the adapter resolved for the message's source moments earlier. The state-event handlers already invalidate that cache when the room changes, and a restart starts with an empty cache. Room identity reads use gather with return_exceptions enabled. A cancelled read therefore returns CancelledError as a result. The state read previously treated cancellation as usable data, while the member read attempted to unpack the cancellation object. Propagate non-Exception control-flow failures before the ordinary read-error fallback. The two cancellation rows fail on the original public source. They pass with the correction, and the existing ordinary-exception controls pass on both sources. --- plugins/platforms/matrix/adapter.py | 78 ++++++++++++++++++++++------- tests/gateway/test_matrix.py | 77 ++++++++++++++++++++++++++++ 2 files changed, 138 insertions(+), 17 deletions(-) diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index 601af27db5c7c..1ebfb2659658a 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -76,6 +76,12 @@ "PRIVATE": "private_chat", "PUBLIC": "public_chat", "TRUSTED_PRIVATE": "trusted_private_chat"}) TrustState = type("_TrustStateStub", (), {"UNVERIFIED": 0, "VERIFIED": 1}) # type: ignore[misc,assignment] +try: + from mautrix.errors import MNotFound +except ImportError: + class MNotFound(Exception): # type: ignore[no-redef] + """Import-safe stand-in for the homeserver's M_NOT_FOUND error.""" + from gateway.config import Platform, PlatformConfig from gateway.platforms.base import ( gateway_trust_env, BasePlatformAdapter, ExecApprovalPrompt, @@ -343,7 +349,8 @@ class MatrixRoomIdentity: canonical_alias: str | None server_name: str | None joined_member_count: int | None - members_digest: str | None + # None when any state or member read failed.

Name, topic and member changes did not have this problem because they were derived from the saved snapshot. Add the join rule, history visibility, encryption and tombstone to the room snapshot. The identity reads their state events in the same concurrent, time-limited batch as the name and topic, and the turn hook compares them with the snapshot saved on the latest user row. Every note kind is now acknowledged only when the row that reported it is saved, and a restarted gateway also reports changes that happened while it was stopped. A baseline taken from the session origin leaves these fields unknown, so the first turn of a session records them without a note.

The two declarations were independent, so two inconsistent adapters were possible. One with the flag and no hook froze the prompt and never reported a rename. One with the hook and no flag reported a rename in the user turn and also rewrote the system prompt. Remove the flag. reports_turn_context decides both behaviours from whether the adapter overrides prepare_turn_context, and the hook's docstring states that an override must report name and topic changes. Matrix, the only adapter that used either, keeps its behaviour. The reset test inserts its adapter into the runner adapter mapping, which requires BasePlatformAdapter.

The source then showed the alias, the member-derived name or the room ID, and no topic, and the adapter cached that identity for the identity TTL. A failed member read had the same effect on an unnamed room, whose name fell back to the room ID. New sessions and resets in that window took the degraded names into their origin, and tools saw them, until a later refresh restored the real names. Keep the last value read for each room's name, topic, canonical alias and member-derived name, and use it when the corresponding read fails. A successful read replaces the value, so a state event that empties or removes the name or topic still applies. Only M_NOT_FOUND means that the state is absent. The check also accepts an error that only has an M_NOT_FOUND errcode, which is how the room-instructions branch (#125676) recognises it, and the values use the same _room_state_values map as that branch, so the two branches agree when they meet. The values live apart from the identity cache because _absorb_sync clears that cache whenever a sync response includes joined rooms, so the cached identity is usually gone when a later refresh fails. --- plugins/platforms/matrix/adapter.py | 48 ++++++++++++++++++++++------- tests/gateway/test_matrix.py | 47 ++++++++++++++++++++++++++++ 2 files changed, 84 insertions(+), 11 deletions(-) diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index e6487a7f261bd..2c3d0151ca35b 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -430,6 +430,7 @@ def _resolve_max_message_length(config) -> int: _STARTUP_GRACE_SECONDS = 5 # ignore messages older than this many seconds before startup _ROOM_STATE_READ_TIMEOUT_SECONDS = 10.0 +_ROOM_NAME_STATE_KEYS = {"m.room.name": "name", "m.room.topic": "topic", "m.room.canonical_alias": "alias"} _OUTBOUND_MENTION_RE = re.compile(r"(?

Compaction replaced the summarised rows with a summary row that had no snapshot. When the summarised rows included every snapshot newer than the protected head, the baseline became an older snapshot in the head (the first turn's, with the default protect_first_n) or the session origin once the head no longer protects any user row. The next turn then repeated a name or topic note that the model had already seen, and it compared member and security state against stale or unknown values. Compaction removes the rows that contain the baseline, so compaction now keeps it. keep_newest_channel_state in agent/message_metadata.py records the newest snapshot of the original rows on the summary row (or on the tail row that absorbs the summary) when the compacted rows no longer have it as their newest. Tail rows come after the summary row, so a newer snapshot in the tail still wins. record_absorbed_message, which every fold of one row into another calls, applies the same rule, so the survivor of a merge of adjacent user rows (micro-compaction, alternation repair) keeps the later row's snapshot. The summary row can be an assistant row, so the gateway now reads the newest snapshot on a row of any role. CHANNEL_STATE_METADATA_KEY moves to agent/message_metadata.py because the compressor needs it, and acknowledged_channel_state is replaced by newest_channel_state. --- agent/context_compressor.py | 10 ++++++-- agent/message_metadata.py | 32 +++++++++++++++++++++++- gateway/run_inbound_turn_context.py | 25 ++++++------------- tests/agent/test_message_metadata.py | 22 ++++++++++++++++- tests/gateway/test_matrix.py | 37 ++++++++++++++++++++++++++++ 5 files changed, 104 insertions(+), 22 deletions(-) diff --git a/agent/context_compressor.py b/agent/context_compressor.py index 8863e0190cd64..bae5fad4234ed 100644 --- a/agent/context_compressor.py +++ b/agent/context_compressor.py @@ -35,6 +35,7 @@ from agent.context_compressor_prellm import PreLlmSkipMixin from agent.context_compressor_summary import SummaryDispatchMixin from agent.error_classifier import FailoverReason, classify_api_error +from agent.message_metadata import keep_newest_channel_state from agent.micro_compaction import MicroCompactionMixin from agent.prompt_builder import STEER_DISPLAY_KIND from agent.model_metadata import ( @@ -5745,14 +5746,16 @@ def _assemble_compressed( summary_role, merge_into_tail, force_user_leading, first_tail_visible_idx = ( self._summary_placement(compressed, tail_messages, compress_start) ) + summary_row = None if not merge_into_tail: # End marker stops weak models treating the quoted summary as fresh input (#11475) or # regurgitating it (#33256). - compressed.append({ + summary_row = { "role": summary_role, "content": summary + "\n\n" + _SUMMARY_END_MARKER, COMPRESSED_SUMMARY_METADATA_KEY: True, COMPRESSED_SUMMARY_HAS_USER_TURN_KEY: bool(self._summary_has_user_turn), - }) + } + compressed.append(summary_row) # Default carrier is tail[0]: an exempt row absorbs the summary invisibly.

It removed those lines from the message text and reported them as the text of the replied-to message. Matrix 1.13 (MSC2781) removed reply fallbacks, and current clients such as Element X send a reply exactly as the user typed it. A user who began a reply with a quotation therefore lost the quotation, and the agent saw it as the message being replied to. Element also sets m.in_reply_to, with is_falling_back, on ordinary thread messages, so a quote at the start of a thread message was lost in the same way. Treat the leading quote as a fallback only when the event has one: the HTML body starts with an element, or the plain quote block starts with the quoted sender's pill ("> <@user:server>", or "> * <@user:server>" for an emote) and ends with a blank line. Older clients generate both forms. The reply-context parse and the mention strip under require_mention use the same check, so a quote without a fallback stays in the text with any bot mention removed, as it does in a message that is not a reply. The plain-body check is deliberately narrower than the spec. The spec's stripping note still says to remove every leading "> " line of a reply without condition, and that rule cannot tell a fallback from a quote now that clients no longer send fallbacks. Ruma's remove_plain_reply_fallback, which matrix-rust-sdk and Element X use, narrows it in the same way: it strips only a body that starts with "> <" or "> * <". The HTML check follows the spec's rule for formatted_body, which applies only when it starts with . A hand-typed quote that starts with a pill and ends with a blank line has the same shape as a plain fallback and is still stripped. --- plugins/platforms/matrix/adapter.py | 36 +++++++-- .../test_matrix_message_event_metadata.py | 80 +++++++++++++++++++ 2 files changed, 110 insertions(+), 6 deletions(-) diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index 2c3d0151ca35b..f72a81725641a 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -272,6 +272,30 @@ def _split_reply_fallback(body: str) -> tuple[str, str]: return (head, "") if idx >= len(lines) else (head + "\n", "\n".join(lines[idx:])) +_MATRIX_REPLY_FALLBACK_FIRST_LINE_RE = re.compile(r"^> (?:\* )?<@[^>\s]+>") + + +def _has_reply_fallback(body: str, content: dict) -> bool: + """Whether a reply's body starts with a legacy reply fallback instead of the user's own quote. + + Matrix 1.13 (MSC2781) removed reply fallbacks, so a modern client sends the reply as typed + and a leading ``> `` block is the user's quotation.

When two messages quote different messages, batching their text keeps only the first quote. The busy-text debounce also overwrote the quote ID with a later inbound message ID. Split ingress batches when their reply contexts differ. Dispatch the earlier event through Telegram's tracked inbound redispatch queue so a concurrent disconnect preserves the event for reconnect. A metadata-free continuation after a near-limit chunk inherits the first chunk's quote, which Telegram clients can omit from later parts of a split message. Compare reply context during busy-text debounce as well, and keep the quote ID distinct from the inbound message that an answer should target.

Iain Lane Date: Wed, 30 Sep 2026 10:00:56 +0100 Subject: [PATCH 43/87] fix(gateway): keep reply context when busy follow-ups merge Messages that arrive while a turn is running can be merged into one pending event. merge_pending_message_event joins a follow-up into the pending slot, and with busy_text_mode queue, _queue_text_debounce first joins a burst of text into one buffered event. A merged event has one set of reply_to_* fields, and neither path copied them from the incoming message. If a user sent "one" and then replied to an earlier message with "two", the next turn had no reply pointer, so the agent could not tell which message "two" referred to. The debounce also dropped a quoted image from the incoming media_urls. The previous commit, from #65526, stops the debounce from merging messages whose reply contexts differ in any way. That keeps two reply targets apart, but it also splits a plain message from a reply that follows it, and merging those two would lose nothing. The debounce has two places where a queued turn can wait: the pending slot and its own buffer. Every split uses one of them, and a third message that fits neither was dropped. Copy the reply context instead where that loses nothing. MessageEvent.absorb_reply_context gives an event without a reply context the incoming one. Both branches of merge_pending_message_event and the debounce buffer call it, and the buffer now also takes the incoming media, as _enqueue_text_event does. MessageEvent.reply_context_conflicts is true only when both events reply to a message and their reply contexts differ. The debounce keeps those messages as separate turns, as it already does for messages from different senders. If the pending slot and the buffer both reply to other messages, a third message from the same sender joins the buffer. The buffer keeps its own reply context, so the third message's text reaches the agent but its reply context does not. merge_pending_message_event has to store every event in the single pending slot. When two reply contexts conflict there, the event keeps the first one, which is the rule that #62088 applies to Matrix merges. #66027 made the newest message's reply context replace the older one. That drops the older reply target, and it clears a quote when the newest message has none, so this change does not adopt it. Its coverage of both merge_pending_message_event branches and of the debounce is kept.

A false flag means the attachment's text is not in the message. Losing that flag changes it to the legacy inlined state when the gateway builds document context. Pad legacy flag lists to the existing attachment count before appending new media. Append incoming flags and pad any legacy incoming entries as well, so each merged attachment keeps its own text-inlining contract. Consolidate the reply and media checks into two parameterized behavior contracts that compare complete events. Telegram dispatch checks await tracked tasks with zero batching delays instead of assuming that a short wall-clock sleep is enough under runner load. Three attachment cases reproduced missing flags before the repair and pass with the aligned lists. The contracts also retain the documented single-slot fallback for adapters without separate-turn storage. --- gateway/platforms/base.py | 11 +- .../gateway/test_active_session_text_merge.py | 289 +++++++++--------- tests/gateway/test_telegram_text_batching.py | 201 ++++-------- 3 files changed, 214 insertions(+), 287 deletions(-) diff --git a/gateway/platforms/base.py b/gateway/platforms/base.py index 65ef3180904c6..4adac498fa06a 100644 --- a/gateway/platforms/base.py +++ b/gateway/platforms/base.py @@ -3890,8 +3890,6 @@ async def _queue_text_debounce(self, session_key: str, event: MessageEvent) -> N return if not self._same_text_debounce_sender(state.event, event): return - # The pending slot and this buffer are the only places where a queued turn can wait, - # and both reply to other messages.

The adapter treated that fallback pointer as a user reply, so it attributed the continuation to the thread root. Parse relations into explicit reply, thread fallback and edit fields. Use the parsed reply target for inbound context and the thread root for session routing. Malformed relation content now yields an empty relation instead of failing message handling. --- plugins/platforms/matrix/adapter.py | 9 +++--- plugins/platforms/matrix/relations.py | 35 +++++++++++++++++++++ tests/gateway/test_matrix.py | 44 +++++++++++++++++++++++++++ 3 files changed, 84 insertions(+), 4 deletions(-) create mode 100644 plugins/platforms/matrix/relations.py diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index f91fe5d98c088..11ae5a5d11dbe 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -83,6 +83,7 @@ class MNotFound(Exception): # type: ignore[no-redef] """Import-safe stand-in for the homeserver's M_NOT_FOUND error.""" from gateway.config import Platform, PlatformConfig +from plugins.platforms.matrix.relations import MatrixRelation from gateway.platforms.base import ( gateway_trust_env, BasePlatformAdapter, ExecApprovalPrompt, SendResult, resolve_proxy_url, proxy_kwargs_for_aiohttp, _ssrf_redirect_guard, @@ -2108,7 +2109,7 @@ async def _on_room_message(self, event: Any) -> None: source_content = content.serialize() if hasattr(content, "serialize") else {} msgtype = str(content.msgtype) if hasattr(content, "msgtype") else "" relates_to = source_content.get("m.relates_to", {}) - if relates_to.get("rel_type") == "m.replace": # skip edits + if MatrixRelation.from_content(relates_to).is_edit: return # m.notice is the conventional bot-response msgtype; ignoring it prevents bot-to-bot loops. if msgtype == "m.notice" and not self._process_notices: @@ -2129,7 +2130,7 @@ async def _resolve_message_context( identity = await self._resolve_room_identity(room_id) is_dm = await self._is_dm_room(room_id) chat_type = "dm" if is_dm else "group" - thread_id = _thread_root(relates_to) + thread_id = MatrixRelation.from_content(relates_to).thread_root is_mentioned = mention_claimed or self._content_mentions_bot(body, source_content) if not is_dm: # Whitelist first: non-listed rooms are dropped even when @mentioned (DMs exempt). @@ -2160,7 +2161,7 @@ async def _resolve_message_context( # for reply_to_author_id.

The gateway then knew only the target event ID and could not tell the agent what message the user referenced or who wrote it. Resolve reply targets from a bounded cache or the room event API. Apply edits to cached text and keep redactions as empty cache entries so a later reply cannot revive deleted content. Decrypt fetched events when the room uses E2EE, and label media bodies so filenames are not treated as spoken text. Attach the target author's name and authorisation verdict to the inbound event. The gateway marks fetched content from an unauthorised author as unverified background and renders Matrix quotes on one line. The adapter never fetches a remote target for a sender it rejects.

From: Iain Lane Date: Sun, 27 Sep 2026 11:57:41 +0100 Subject: [PATCH 47/87] feat(matrix): restore quoted media and new thread context An explicit Matrix reply could identify its parent but gave the agent only a filename when that parent was an image. Threaded messages in a fresh gateway session lacked the earlier messages that explain them. Resolve reply targets through a bounded room-event cache, decrypting when needed. Download quoted images through the existing Matrix media path and attach their cached files to the triggering message. Read the thread root and recent relations for a new threaded session, then attribute and bound the prior messages before adding them to the user turn. Add external thread text after local @ reference expansion so it cannot trigger a file read. Use mautrix.api.Method.GET for the relations request because mautrix 0.21.1 treats a string method as a non-GET request and adds a body. Cache successful outbound messages by event ID for immediate replies, and preserve reply context when a later text chunk joins a batch. Mark inline fallback quotes as unverified because their author pills come from the sender and can claim the bot's identity. Expose a config.yaml limit for thread backfill and preserve room state context when both appear. Upstream now measures the outbound limit in UTF-8 bytes. Keep the 15000-byte setting beside the thread-backfill option in the guide. Co-authored-by: Wessel <2385844+weebl2000@users.noreply.github.com> Maintenance-adaptation: Use the concrete encrypted-event SDK factory and its JSON boundary for the already admitted encrypted dictionary.

They also did not prepare two thread sessions from the same room. Drive both media replies through the adapter, including a failed parent fetch, and prepare separate thread turns through the gateway. These cases establish that an unavailable parent does not drop the media and that each thread receives its own earlier context.

Strip that quote before admission and command normalisation so quoted text cannot enter the current turn and a following command remains actionable. Thread backfill cached images as text. A later explicit reply then used the text entry without trying to load the image, even after a failed download. Mark cached images and retry their media load when a reply needs it. A successful outbound edit left the original event cached at its first sent fragment. Update that event only after the edit succeeds. Keep a redaction tombstone authoritative when a late replacement arrives, so an edited message cannot revive redacted content. Five red invariants now pass, including root and child image cases. Upstream now bounds edit events in UTF-8 bytes and shortens their fallback text when the duplicate content exceeds the event budget. Keep that budgeting before the send, then update the cached parent only after the edit succeeds. Use the transmitted replacement content so the shortened fallback cannot replace the final answer in replies. Exercise successful, failed and cancelled sends with live and redacted parents. Failed or cancelled edits must preserve the published cache entry, and late edits must not revive a redacted parent. Maintenance-adaptation: Assert that both cache results exist before the existing complete tuple assertion reads their fields. --- plugins/platforms/matrix/adapter.py | 17 +- plugins/platforms/matrix/reply_context.py | 30 +++- plugins/platforms/matrix/thread_context.py | 5 +- tests/gateway/test_matrix.py | 176 +++++++++++++++++++++ 4 files changed, 216 insertions(+), 12 deletions(-) diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index d7342738f4287..0b76369779da7 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -1573,7 +1573,10 @@ async def edit_message(self, chat_id: str, message_id: str, content: str, *, fin # JSON escaping grows a character at most sixfold (\u00XX). fallback = formatted.encode("utf-8")[: max(0, room // 6)].decode("utf-8", "ignore") msg_content["body"] = f"* {fallback}…" - return await self._send_content_event(chat_id, msg_content) + result = await self._send_content_event(chat_id, msg_content) + if result.success: + self._event_context_cache.apply_edit(chat_id, self._user_id or "", msg_content) + return result async def send_image( self, chat_id: str, image_url: str, caption: Optional[str] = None, reply_to: Optional[str] = None, @@ -2151,7 +2154,10 @@ async def _resolve_message_context( identity = await self._resolve_room_identity(room_id) is_dm = await self._is_dm_room(room_id) chat_type = "dm" if is_dm else "group" - thread_id = MatrixRelation.from_content(relates_to).thread_root + relation = MatrixRelation.from_content(relates_to) + thread_id = relation.thread_root + if relation.thread_fallback_target: + body = _normalize_matrix_bang_command(_strip_reply_fallback(body)) is_mentioned = mention_claimed or self._content_mentions_bot(body, source_content) if not is_dm: # Whitelist first: non-listed rooms are dropped even when @mentioned (DMs exempt). @@ -2182,7 +2188,7 @@ async def _resolve_message_context( # for reply_to_author_id.

client Unit tests cover relation parsing and thread backfill in isolation, but they cannot prove that a second Matrix client delivers those events through the live gateway into separate model conversations. Send two thread roots and legacy fallback continuations through the disposable Synapse service. Wait for each final reply, then inspect the fake model requests. The test checks that quoted fallback text is removed and each request contains only its own thread root and turn. Live Matrix request/reply waits cover real HTTP sends, text batching, and the first gateway turn. A cold-service exchange produced a valid reply after 21.981 seconds, beyond the previous 15-second bound. Use the fixture's existing 60-second wait bound and keep the complete thread, reply and model-context assertions. --- .../matrix_live/test_thread_context.py | 89 +++++++++++++++++++ 1 file changed, 89 insertions(+) create mode 100644 tests/integration/matrix_live/test_thread_context.py diff --git a/tests/integration/matrix_live/test_thread_context.py b/tests/integration/matrix_live/test_thread_context.py new file mode 100644 index 0000000000000..a2f448ccbc5a0 --- /dev/null +++ b/tests/integration/matrix_live/test_thread_context.py @@ -0,0 +1,89 @@ +"""A separate Matrix client checks fallback quotes and thread model context.""" + +from __future__ import annotations + +import asyncio +import json +import time +from collections.abc import Callable + +import pytest +from nio import RoomMessageText, RoomSendResponse + +from tests.integration.matrix_live.conftest import LiveGateway, LiveRoom + + +def test_thread_fallback_keeps_model_context_in_its_thread( + gateway: LiveGateway, + live_room: LiveRoom, + record_property: Callable[[str, object], None], +) -> None: + async def exchange() -> None: + client = live_room.observer.client(live_room.homeserver) + bot_replies: set[str] = set() + try: + await client.sync(timeout=0) + + async def send_thread(label: str) -> None: + root = await client.room_send( + live_room.room_id, + "m.room.message", + {"msgtype": "m.notice", "body": f"Thread {label} root [root:{label}]"}, + ) + assert isinstance(root, RoomSendResponse), root + body = ( + f"> <{live_room.observer.user_id}> quoted sentinel {label} " + "@file:/tmp/private\n\n" + f"Question [thread:{label}]" + ) + sent = await client.room_send( + live_room.room_id, + "m.room.message", + { + "msgtype": "m.text", "body": body, + "m.relates_to": { + "rel_type": "m.thread", "event_id": root.event_id, + "is_falling_back": True, + "m.in_reply_to": {"event_id": root.event_id}, + }, + }, + ) + assert isinstance(sent, RoomSendResponse), sent + + while True: + response = await client.sync(timeout=250) + joined = response.rooms.join.get(live_room.room_id) + if joined: + bot_replies.update( + event.event_id for event in joined.timeline.events + if isinstance(event, RoomMessageText) and event.sender == live_room.bot.user_id + ) + if len(bot_replies) >= (1 if label == "A" else 2): + return + + for label in ("A", "B"): + try: + await asyncio.wait_for(send_thread(label), timeout=60) + except asyncio.TimeoutError: + pytest.fail( + f"No Matrix thread {label} reply after 60 seconds.

WhatsApp and Signal can fill that field with the quoted participant's phone number, so a group reply sent a third party's number to the model even with privacy.redact_pii enabled. Matrix reply quotes were also cut to 500 characters and collapsed onto one line, which undid 6efca62c20 and dropped the end of long tracebacks, lists and code. Identify the author only when the adapter set reply_to_author_authorized, which only the Matrix adapter does after checking the quoted sender. Other platforms get the unattributed pointer again. When an attributed pointer has only an ID, the ID goes through _should_redact_pii and _hash_sender_id like the session context prompt. The quoted text is kept whole on every platform, and only the author label is reduced to one line. --- gateway/platforms/event.py | 2 + gateway/run_inbound.py | 48 +++++++++++------- tests/gateway/test_reply_to_injection.py | 62 ++++++++++++++++++++++-- 3 files changed, 92 insertions(+), 20 deletions(-) diff --git a/gateway/platforms/event.py b/gateway/platforms/event.py index eb594301cb3b1..de6a6bfdc3d15 100644 --- a/gateway/platforms/event.py +++ b/gateway/platforms/event.py @@ -115,6 +115,8 @@ class MessageEvent: # Snapshot from ``BasePlatformAdapter.prepare_turn_context``.

For an older, evicted or pre-restart event, it stored the edit's m.new_content under the target's event ID with the editor as sender. Reply resolution and thread backfill then used that entry and did not fetch the real event. Any room member could therefore replace the quoted text of someone else's message or of a thread root. The Matrix spec requires clients to ignore an m.replace from a different sender. Accept an edit only when the original is cached and has the same sender. Otherwise leave the cache unchanged, so the next resolve fetches the event and reads the replacement that the server bundles, which is limited to the original sender's edits. --- plugins/platforms/matrix/reply_context.py | 10 ++++----- tests/gateway/test_matrix.py | 25 +++++++++++++++++++++++ 2 files changed, 29 insertions(+), 6 deletions(-) diff --git a/plugins/platforms/matrix/reply_context.py b/plugins/platforms/matrix/reply_context.py index 36857a388c893..d32ac29071231 100644 --- a/plugins/platforms/matrix/reply_context.py +++ b/plugins/platforms/matrix/reply_context.py @@ -178,15 +178,13 @@ def apply_edit(self, room_id: str, sender: str, content: dict) -> None: if not isinstance(body, str) or not body.strip(): return prior = self._entries.get((room_id, target)) - if prior is not None and prior.redacted: - return - if prior is not None and prior.sender and prior.sender != sender: + # Without the original, the editor cannot be checked against its sender.

Thread backfill deserialises the raw event with mautrix, and the earlier test invocation could not import mautrix, so a test of that path would have skipped the event without failing. Drive both paths with real mautrix events and a crypto fake that decrypts only when the keys are available. A decrypted event supplies the quoted text or the thread entry, and a missing session leaves it out. Replacing either decryption call with a no-op fails all four cases. Maintenance-adaptation: Use the concrete SDK message and encrypted-event factories for their existing literal event types, with the SDK JSON and SessionID constructors. Keep every dictionary value unchanged. --- tests/gateway/test_matrix.py | 76 ++++++++++++++++++++++++++++++++++++ 1 file changed, 76 insertions(+) diff --git a/tests/gateway/test_matrix.py b/tests/gateway/test_matrix.py index e0164f990dfc6..8bd2ff4c81e00 100644 --- a/tests/gateway/test_matrix.py +++ b/tests/gateway/test_matrix.py @@ -1740,6 +1740,82 @@ async def test_thread_backfill_leaves_out_every_chunk_of_a_batched_turn(): ) +def _encrypted_event(event_id, body, *, keys_available): + """A raw megolm event and a crypto fake that decrypts it only when the session keys exist.""" + from mautrix.errors import SessionNotFound + from mautrix.types import ( + EncryptedEvent, + JSON, + MessageEvent as MatrixMessageEvent, + SessionID, + ) + + common = {"event_id": event_id, "sender": "@alice:example.org", + "room_id": "!room:example.org", "origin_server_ts": 1} + raw = {**common, "type": "m.room.encrypted", "content": { + "algorithm": "m.megolm.v1.aes-sha2", "ciphertext": "AAAA", "session_id": "session", + "sender_key": "sender-key", "device_id": "DEVICE", + }} + decrypted = MatrixMessageEvent.deserialize( + JSON({ + **common, + "type": "m.room.message", + "content": {"msgtype": "m.text", "body": body}, + }) + ) + + async def decrypt_megolm_event(event): + assert isinstance(event, EncryptedEvent) + if not keys_available: + raise SessionNotFound(SessionID("session")) + return decrypted + + return raw, types.SimpleNamespace(decrypt_megolm_event=AsyncMock(side_effect=decrypt_megolm_event)) + + +@pytest.mark.asyncio +@pytest.mark.parametrize("keys_available,expected", [ + (True, ("secret", "@alice:example.org")), + (False, (None, None)), +]) +async def test_encrypted_reply_target_is_decrypted_when_keys_are_available(keys_available, expected): + from mautrix.types import EncryptedEvent, JSON + + raw, crypto = _encrypted_event("$parent", "secret", keys_available=keys_available) + adapter = _make_room_adapter() + adapter._client.get_event = AsyncMock(return_value=EncryptedEvent.deserialize(JSON(raw))) + adapter._client.crypto = crypto + + event = await adapter._build_inbound_event( + "!room:example.org", "@bob:example.org", "$reply", "what does it say?", + {"msgtype": "m.text", "body": "what does it say?"}, + {"m.in_reply_to": {"event_id": "$parent"}}, + ) + + assert (event.reply_to_text, event.reply_to_author_id) == expected + crypto.decrypt_megolm_event.assert_awaited_once() + + +@pytest.mark.asyncio +@pytest.mark.parametrize("keys_available,expected", [ + (True, "[Earlier messages in this thread]\n[alice] root\n[alice] secret"), + (False, "[Earlier messages in this thread]\n[alice] root"), +]) +async def test_encrypted_thread_event_is_decrypted_when_keys_are_available(keys_available, expected): + raw, crypto = _encrypted_event("$child", "secret", keys_available=keys_available) + adapter = _make_room_adapter() + adapter._client.api.request = AsyncMock(return_value={"chunk": [raw]}) + adapter._client.get_event = AsyncMock(return_value=types.SimpleNamespace( + sender="@alice:example.org", content={"msgtype": "m.text", "body": "root"}, + )) + adapter._client.crypto = crypto + + context = await adapter.fetch_thread_context("!room:example.org", "$root") + + assert context == expected + crypto.decrypt_megolm_event.assert_awaited_once() + + @pytest.mark.asyncio async def test_thread_fetch_uses_mautrix_get_method(): from enum import Enum From 48afd677c91abbaf34064f2160afa063af49fbc1 Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Tue, 29 Sep 2026 20:05:15 +0100 Subject: [PATCH 58/87] fix(matrix): fetch thread history through the turn-context hook The gateway core fetched earlier thread messages for a new Matrix thread session itself. `_prepare_inbound_message_text` checked `source.platform == Platform.MATRIX` and `hasattr(adapter, "fetch_thread_context")`, which put Matrix-specific code in the runner beside the generic `prepare_turn_context` hook that the room-context layer added for room-state notes. The two paths also disagreed about the `[New message]` marker. The thread history went in front of the message text, and the room note with its marker was prepended afterwards. When a room note was pending and a message started a new thread session, the model received [New message] [Earlier messages in this thread] ... so the marker labelled the thread history as part of the new message. Move the thread fetch into `MatrixAdapter.prepare_turn_context`. The hook gains a `first_turn` argument, which the core sets when the session transcript is empty, so an adapter can add history that only a new session needs. The Matrix adapter returns the room note followed by the thread history as one note, and the core puts the single `[New message]` marker after all of it, before the reply pointer and the message. The marker also follows thread history when no room note is pending, as it already follows the Discord history backfill. `TurnContextUpdate.channel_state` becomes optional. The adapter reads room state only for text messages, and a failed read gives no snapshot, but thread history is still reported in both cases; a `None` snapshot leaves the saved state unchanged. The core no longer checks the platform here, and any adapter can report first-turn context through the same hook. Maintenance-adaptation: Accept the optional event identifiers in both thread-context collection declarations. Keep the replacement context fixture on the proper monkeypatch seam and include first_turn in the published parent reset fixture hook. --- gateway/platforms/base.py | 10 ++- gateway/platforms/event.py | 5 +- gateway/run_inbound.py | 18 ---- gateway/run_inbound_turn_context.py | 20 +++-- plugins/platforms/matrix/adapter.py | 33 ++++++-- plugins/platforms/matrix/thread_context.py | 2 +- tests/gateway/test_matrix.py | 78 +++++++++++++++-- tests/gateway/test_reply_to_injection.py | 99 ++++++++-------------- tests/gateway/test_session.py | 4 +- 9 files changed, 158 insertions(+), 111 deletions(-) diff --git a/gateway/platforms/base.py b/gateway/platforms/base.py index 7cf04ab54d2ea..cba382ee8549f 100644 --- a/gateway/platforms/base.py +++ b/gateway/platforms/base.py @@ -3536,14 +3536,16 @@ def pop_post_delivery_callback( async def prepare_turn_context( self, event: MessageEvent, *, origin: Optional[SessionSource], - acknowledged_state: Optional[Dict[str, Any]], + acknowledged_state: Optional[Dict[str, Any]], first_turn: bool, ) -> Optional[TurnContextUpdate]: - """Report changes to the chat since the conversation last acknowledged its state. + """Report context for this turn: changes to the chat since the conversation last + acknowledged its state, and earlier messages that a new session has not seen.

This branch's _strip_thread_reply_fallback used its own copy of the pill regex and checked the pill alone. The explicit-reply path in _extract_reply_context still treated any leading "> " as a fallback, because this branch's signature passed only formatted_body, and _has_reply_fallback needs the whole content. Use _has_reply_fallback for thread messages and for explicit replies, and remove _strip_thread_reply_fallback and its duplicate regex. _extract_reply_context now takes source_content as a positional argument before relates_to, as in #128621, and reads formatted_body from it. The sender and chat_type keywords remain. Two test expectations change: - In #128621's test_reply_strips_only_a_reply_fallback, the thread-message-own-quote case now expects no reply_to_message_id. This branch treats m.in_reply_to under is_falling_back as the thread's fallback target, not an explicit reply, so the event is not a reply. The message text, which is what that case checks, is unchanged. - test_thread_message_strips_only_the_reply_fallback gains a case for a thread message whose quote starts with a pill but has no blank line after it. The pill-only rule stripped that quote; the shared rule keeps it as the user's text.

Their checks disagreed. _has_reply_fallback required format "org.matrix.custom.html" and a bare "" tag. extract_mx_reply_quote ignored format and accepted any body that started with ", or the event had no format field, and the plain-text quote had no pill, the message kept the quote and reply_to_text repeated it. The model then saw the quote twice. Add starts_with_mx_reply(content) to reply_context.py and call it from both helpers. It requires the HTML format and matches an start tag with or without attributes, because the spec defines the fallback as a formatted_body that "begins with an start tag". The match ignores case because the quote extractor's HTML parser lower-cases tag names, so the check accepts every tag that the extractor reads as . extract_mx_reply_quote now takes the event content instead of the formatted body because it needs the format field. --- plugins/platforms/matrix/adapter.py | 7 +++--- plugins/platforms/matrix/reply_context.py | 21 ++++++++++++---- tests/gateway/test_matrix.py | 20 +++++++++------- .../test_matrix_message_event_metadata.py | 24 +++++++++++++++++++ 4 files changed, 55 insertions(+), 17 deletions(-) diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index 70f8d7f8bed97..f1e5c660af853 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -90,6 +90,7 @@ class MNotFound(Exception): # type: ignore[no-redef] from plugins.platforms.matrix.relations import MatrixRelation from plugins.platforms.matrix.reply_context import ( MatrixEventContext, MatrixEventContextCache, MatrixReplyContext, extract_mx_reply_quote, + starts_with_mx_reply, ) from plugins.platforms.matrix.thread_context import fetch_thread_entries from gateway.platforms.base import ( @@ -293,9 +294,7 @@ def _has_reply_fallback(body: str, content: dict) -> bool: """ if not body.startswith("> "): return False - formatted_body = content.get("formatted_body") - if (content.get("format") == "org.matrix.custom.html" and isinstance(formatted_body, str) - and formatted_body.lstrip().startswith("")): + if starts_with_mx_reply(content): return True if not _MATRIX_REPLY_FALLBACK_PILL_RE.match(body): return False @@ -2236,7 +2235,7 @@ async def _extract_reply_context( if reply_to_author_id: reply_to_author_name = await self._get_display_name(room_id, reply_to_author_id) if reply_to and not reply_to_text: - reply_to_text = extract_mx_reply_quote(source_content.get("formatted_body")) + reply_to_text = extract_mx_reply_quote(source_content) if reply_to_text: reply_to_author_authorized = False if reply_to and ( diff --git a/plugins/platforms/matrix/reply_context.py b/plugins/platforms/matrix/reply_context.py index d32ac29071231..69cc11f2daf5b 100644 --- a/plugins/platforms/matrix/reply_context.py +++ b/plugins/platforms/matrix/reply_context.py @@ -4,11 +4,12 @@ import asyncio import logging +import re from collections import OrderedDict from dataclasses import dataclass from html.parser import HTMLParser from pathlib import Path -from typing import Any, Awaitable, Callable +from typing import Any, Awaitable, Callable, Mapping logger = logging.getLogger(__name__) @@ -120,12 +121,24 @@ def text(self) -> str: return "".join(self._parts) -def extract_mx_reply_quote(formatted_body: Any) -> str | None: - if not isinstance(formatted_body, str) or not formatted_body.lstrip().startswith("])", re.IGNORECASE) + + +def starts_with_mx_reply(content: Mapping[str, Any]) -> bool: + """Whether the event's HTML body starts with an ```` start tag, with or without + attributes.

A new Matrix thread session therefore fetched an earlier trigger as thread history and included the same text again in the current user message. Record each previous anchor and incoming batch's merged IDs before the anchor changes. Thread-history preparation can then exclude every event already represented in the current turn. Input without a new anchor keeps its existing anchor and still contributes its merged IDs. Extend the real model-preparation invariant to both ingress and busy batching. The busy case repeated the first trigger before this change and now excludes it. Independent full-event expectations also reproduce six missing-ID cases and pass after the fix.

All context paths now strip only a recognized legacy sender pill or a formatted mx-reply fallback. Edits use the replacement content to identify its formatting correctly. One parameterized behavior contract checks all three context paths against user quotations and both legacy fallback formats.

The Matrix client-server specification recommends the latest known message for this fallback target. --- plugins/platforms/matrix/adapter.py | 27 +++++++++-- .../platforms/matrix/outbound_relations.py | 29 ++++++++++++ tests/gateway/test_matrix.py | 47 ++++++++++++++++--- 3 files changed, 91 insertions(+), 12 deletions(-) create mode 100644 plugins/platforms/matrix/outbound_relations.py diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index cf72c2d6249f8..36d61fd6cafad 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -87,6 +87,7 @@ class MNotFound(Exception): # type: ignore[no-redef] """Import-safe stand-in for the homeserver's M_NOT_FOUND error.""" from gateway.config import Platform, PlatformConfig +from plugins.platforms.matrix.outbound_relations import ThreadFallbackTracker from plugins.platforms.matrix.relations import MatrixRelation from plugins.platforms.matrix.reply_context import ( MatrixEventContext, MatrixEventContextCache, MatrixReplyContext, extract_mx_reply_quote, @@ -857,6 +858,7 @@ def __init__(self, config: PlatformConfig): # because _absorb_sync clears that cache whenever a sync response includes joined rooms. self._room_state_values: Dict[str, Dict[str, Optional[str]]] = {} self._event_context_cache = MatrixEventContextCache() + self._thread_fallbacks = ThreadFallbackTracker() try: self._thread_backfill_limit = max(0, min(100, int(config.extra.get("thread_backfill_limit", 20)))) except (TypeError, ValueError): @@ -1419,7 +1421,9 @@ async def send( for chunk in self.truncate_message( self.format_message(content), self.max_message_length, len_fn=self.message_len_fn): msg_content = self._build_text_message_content(chunk) -

Every chunk became a genuine thread reply with is_falling_back set to false, and Element rendered a quote of the user's message above each chunk. Streamed responses had the same problem: the stream consumer anchors each new chunk on the previous chunk, and later messages in the turn on the triggering event again. In auto-thread rooms the synthetic thread root is the triggering event itself, so the first reply in every new thread quoted its own root. The tracker now records, for each room and thread, whether Hermes sent the latest event and which event Hermes last replied to. A send anchored on the thread root, on Hermes's own latest event, or on an event that already has a reply in the thread is a continuation. It sets is_falling_back to true and points at the latest known event, so only the first message of a response remains a genuine reply. The decision stays in the Matrix plugin, and the platform-neutral chunk anchoring in the stream consumer is unchanged. Unit tests cover a split final response with reply_to, the buffered and live streamed paths, and a reply anchored on the root. A live Synapse test limits the gateway to 500-character messages and checks that only the first chunk of a threaded answer quotes the question. Before this change the second chunk also quoted it. Live Matrix request/reply waits cover real HTTP sends, text batching, and the first gateway turn. A cold-service exchange produced a valid reply after 21.981 seconds, beyond the previous 15-second bound. Use the fixture's existing 60-second wait bound and keep the complete thread, reply and model-context assertions. --- plugins/platforms/matrix/adapter.py | 4 +- .../platforms/matrix/outbound_relations.py | 77 +++++++++-- tests/gateway/test_matrix.py | 125 +++++++++++++++++- tests/integration/matrix_live/conftest.py | 14 +- .../matrix_live/test_thread_context.py | 103 ++++++++++++++- 5 files changed, 303 insertions(+), 20 deletions(-) diff --git a/plugins/platforms/matrix/adapter.py b/plugins/platforms/matrix/adapter.py index 36d61fd6cafad..dc58e932d710d 100644 --- a/plugins/platforms/matrix/adapter.py +++ b/plugins/platforms/matrix/adapter.py @@ -3234,7 +3234,9 @@ def _apply_relation_metadata( relates_to = msg_content.get("m.relates_to", {}) relates_to["rel_type"] = "m.thread" relates_to["event_id"] = thread_id - if reply_to: + if reply_to and not self._thread_fallbacks.is_continuation( + room_id, thread_id, reply_to + ): relates_to["is_falling_back"] = False else: latest = self._thread_fallbacks.latest(room_id, thread_id) diff --git a/plugins/platforms/matrix/outbound_relations.py b/plugins/platforms/matrix/outbound_relations.py index 05f4a67c27fed..c7e961b6c4046 100644 --- a/plugins/platforms/matrix/outbound_relations.py +++ b/plugins/platforms/matrix/outbound_relations.py @@ -1,29 +1,80 @@ """Track the latest Matrix event available for each outbound thread fallback.""" from collections import OrderedDict +from dataclasses import dataclass from typing import Any from plugins.platforms.matrix.relations import MatrixRelation +@dataclass(frozen=True) +class _ThreadEvents: + latest: str + latest_is_own: bool + answered: str | None + + class ThreadFallbackTracker: def __init__(self, max_threads: int = 500) -> None: self._max_threads = max_threads - self._events: OrderedDict[tuple[str, str], str] = OrderedDict() + self._threads: OrderedDict[tuple[str, str], _ThreadEvents] = OrderedDict() def remember(self, room_id: str, thread_id: str, event_id: str) -> None: - if not room_id or not thread_id or not event_id: - return - key = (room_id, thread_id) - self._events[key] = event_id - self._events.move_to_end(key) - if len(self._events) > self._max_threads: - self._events.popitem(last=False) + self._update(room_id, thread_id, event_id, own=False, answered=None) - def remember_sent(self, room_id: str, content: dict[str, Any], event_id: str) -> None: - thread_id = MatrixRelation.from_content(content.get("m.relates_to")).thread_root - if thread_id: - self.remember(room_id, thread_id, event_id) + def remember_sent( + self, room_id: str, content: dict[str, Any], event_id: str + ) -> None: + relation = MatrixRelation.from_content(content.get("m.relates_to")) + if relation.thread_root: + self._update( + room_id, + relation.thread_root, + event_id, + own=True, + answered=relation.reply_target, + ) def latest(self, room_id: str, thread_id: str) -> str | None: - return self._events.get((room_id, thread_id)) + events = self._threads.get((room_id, thread_id)) + return events.latest if events else None + + def is_continuation(self, room_id: str, thread_id: str, reply_to: str) -> bool: + """Whether a send anchored on ``reply_to`` continues output already in the thread. + + The gateway anchors every message of a response on the triggering event, and + the stream consumer anchors each new chunk on the previous one, so only the + first of those messages is a genuine reply.

The tracker recognised a continuation only when reply_to was the event that Hermes had most recently replied to, or Hermes's own event while it was still the latest event in the thread. Any other genuine reply or inbound post replaced those values, so the rest of the response quoted its trigger again. That happens on ordinary gateway paths. A busy acknowledgement for a follow-up is a genuine reply to the follow-up, and the running turn then sends its next segment anchored on the original question. With thread_sessions_per_user, two sessions can answer in one thread at the same time. The stream consumer anchors each head chunk on the previous chunk, and another user can post between the two sends. Keep, for each thread, a bounded list of the recent events that Hermes has given a genuine reply to and of the events that Hermes has sent. A send whose reply_to is in either list is a continuation. The fallback target is still the latest known event in the thread. --- .../platforms/matrix/outbound_relations.py | 35 +++++---- tests/gateway/test_matrix.py | 72 +++++++++++++++++++ 2 files changed, 95 insertions(+), 12 deletions(-) diff --git a/plugins/platforms/matrix/outbound_relations.py b/plugins/platforms/matrix/outbound_relations.py index c7e961b6c4046..aef757828039d 100644 --- a/plugins/platforms/matrix/outbound_relations.py +++ b/plugins/platforms/matrix/outbound_relations.py @@ -1,17 +1,23 @@ """Track the latest Matrix event available for each outbound thread fallback.""" -from collections import OrderedDict -from dataclasses import dataclass +from collections import OrderedDict, deque +from dataclasses import dataclass, field from typing import Any from plugins.platforms.matrix.relations import MatrixRelation +_RECENT_EVENTS_PER_THREAD = 32 -@dataclass(frozen=True) + +def _recent_events() -> deque[str]: + return deque(maxlen=_RECENT_EVENTS_PER_THREAD) + + +@dataclass class _ThreadEvents: latest: str - latest_is_own: bool - answered: str | None + answered: deque[str] = field(default_factory=_recent_events) + sent: deque[str] = field(default_factory=_recent_events) class ThreadFallbackTracker: @@ -46,6 +52,10 @@ def is_continuation(self, room_id: str, thread_id: str, reply_to: str) -> bool: the stream consumer anchors each new chunk on the previous one, so only the first of those messages is a genuine reply.

It could not ask for a recent room message, a thread, or an event when it needed more context. A generic network tool would also lack the receiving bot's crypto store and room policy. Bind the receiving adapter and its event loop to the gateway turn. Add a Matrix-only toolset that reads through that adapter, checks the current room and requester, and bounds event counts and bodies. Use the adapter's sync token for room history and its crypto object for encrypted events. Report missing decryption keys per event so readable neighbours remain available. The focused tests cover the owning loop, room and user gates, thread filtering, encrypted reads, and toolset selection. Co-authored-by: Chris <16943149+nepenth@users.noreply.github.com> Maintenance-adaptation: Room membership and room policy can change while the direct-room lookup awaits. Factor the existing room-policy condition into a synchronous predicate for admission and the post-await membership and room-policy recheck, before requester validation. The original inline adapter doubles bind the real predicate. Event-controlled membership, room-policy and requester cases reproduce stale-policy acceptance and verify refusal before client access. --- gateway/run.py | 3 +- gateway/session_context.py | 22 ++ plugins/platforms/matrix/adapter.py | 28 ++- plugins/platforms/matrix/read_context.py | 181 +++++++++++++++ tests/gateway/test_matrix_read_context.py | 268 ++++++++++++++++++++++ tests/tools/test_matrix_read_tool.py | 101 ++++++++ tools/matrix_read_tool.py | 90 ++++++++ toolsets.py | 8 +- 8 files changed, 698 insertions(+), 3 deletions(-) create mode 100644 plugins/platforms/matrix/read_context.py create mode 100644 tests/gateway/test_matrix_read_context.py create mode 100644 tests/tools/test_matrix_read_tool.py create mode 100644 tools/matrix_read_tool.py diff --git a/gateway/run.py b/gateway/run.py index 9b40970ce41db..17d9c458c10e2 100644 --- a/gateway/run.py +++ b/gateway/run.py @@ -4207,7 +4207,7 @@ def _set_session_env(self, context: SessionContext) -> list: from gateway.session_context import set_session_vars # Async-delivery capability tells async tools whether this channel can wake a later turn.

If the loop had stopped, the tool instead ran the adapter coroutine on its worker loop. That could access the client and crypto store from the wrong loop during shutdown. Reject reads when the owning loop is unavailable. Bound a scheduled read and cancel its future on timeout so a loop that stops after scheduling cannot strand the tool worker. A separate Matrix client also verifies that a model can discover the deferred tool, read a live event, and receive its content in the next model request. Live Matrix request/reply waits cover real HTTP sends, text batching, and the first gateway turn. A cold-service exchange produced a valid reply after 21.981 seconds, beyond the previous 15-second bound. Use the fixture's existing 60-second wait bound and keep the complete thread, reply and model-context assertions. --- .../matrix_live/test_read_tools.py | 112 ++++++++++++++++++ tests/tools/test_matrix_read_tool.py | 44 ++++++- tools/matrix_read_tool.py | 22 ++-- 3 files changed, 166 insertions(+), 12 deletions(-) create mode 100644 tests/integration/matrix_live/test_read_tools.py diff --git a/tests/integration/matrix_live/test_read_tools.py b/tests/integration/matrix_live/test_read_tools.py new file mode 100644 index 0000000000000..a611ab113d5ec --- /dev/null +++ b/tests/integration/matrix_live/test_read_tools.py @@ -0,0 +1,112 @@ +"""A separate Matrix client verifies model-visible reads through the live gateway.""" + +from __future__ import annotations + +import asyncio +import json +import time +from collections.abc import Callable + +from nio import RoomMessageText, RoomSendResponse + +from tests.fakes.fake_llm_provider import Text, ToolCall +from tests.integration.matrix_live.conftest import LiveGateway, LiveRoom + + +def test_model_reads_an_event_from_its_live_matrix_session( + gateway: LiveGateway, + live_room: LiveRoom, + record_property: Callable[[str, object], None], +) -> None: + async def exchange() -> None: + client = live_room.observer.client(live_room.homeserver) + seen: set[str] = set() + try: + await asyncio.wait_for(client.sync(timeout=0), timeout=60) + + async def send_and_wait(body: str) -> str: + sent = await client.room_send( + live_room.room_id, + "m.room.message", + {"msgtype": "m.text", "body": body}, + ) + assert isinstance(sent, RoomSendResponse), sent + + while True: + response = await client.sync(timeout=250) + joined = response.rooms.join.get(live_room.room_id) + if not joined: + continue + for event in joined.timeline.events: + if ( + isinstance(event, RoomMessageText) + and event.sender == live_room.bot.user_id + and event.event_id not in seen + ): + seen.add(event.event_id) + return sent.event_id + + target = await asyncio.wait_for( + send_and_wait("Read target [history:blue]"), timeout=60 + ) + gateway.model.push( + ToolCall("tool_search", {"queries": ["Matrix read event"]}), + ToolCall( + "tool_call", + { + "calls": [ + { + "name": "matrix_read", + "arguments": {"kind": "event", "event_id": target}, + } + ] + }, + ), + Text("Read complete"), + ) + await asyncio.wait_for( + send_and_wait("Read the earlier Matrix event"), timeout=60 + ) + + requests = gateway.model.main_requests() + assert len(requests) == 4 + search_messages = [ + message + for message in requests[2]["messages"] + if message["role"] == "tool" + ] + assert len(search_messages) == 1 + assert "matrix_read" in json.loads(search_messages[0]["content"])["tools"] + tool_messages = [ + message + for message in requests[3]["messages"] + if message["role"] == "tool" + ] + assert len(tool_messages) == 2 + result = json.loads(tool_messages[1]["content"]) + assert isinstance(result["events"][0]["timestamp"], int) + assert { + **result, + "events": [{**result["events"][0], "timestamp": None}], + } == { + "events": [ + { + "event_id": target, + "sender": live_room.observer.user_id, + "body": "Read target [history:blue]", + "msgtype": "m.text", + "thread_id": None, + "timestamp": None, + "sender_authorized": True, + } + ], + "errors": [], + } + finally: + await client.close() + + started = time.monotonic() + try: + asyncio.run(exchange()) + finally: + record_property("body_seconds", round(time.monotonic() -

The read tool also kept its own copy of the mautrix `Method` fallback, and a branch for a `None` decryption result that `decrypt_megolm_event` never returns. A change to how history shows edits or redactions would have had to be made in both places. Move both steps into `thread_context`. `decrypt_history_event` returns the decrypted event or raises `UndecryptableEvent` with the reason that the model sees, and `history_message` returns the message type, the display text and the effective content. The thread backfill skips an event that cannot be decrypted, and the read tool reports it per event as before. Reads now use the backfill's rule for what counts as a message: the effective content has a string body that produces non-empty text. A sticker is therefore readable, and a message without a body is skipped instead of being returned with an empty body. The shared encrypted-history decoder uses the concrete SDK encrypted event declaration and JSON input wrapper. The general Event factory has a dynamically assigned deserialize attribute that its static type does not declare. Fold the later concrete-decoder typing correction into this introducing contribution; the original correction retains its separate attribution. The existing isolated read fixture declares the same concrete decoder and JSON wrapper required by the changed caller. Preserve nullable excluded event IDs from the current parent when the shared decoder replaces the thread helper. The backfill still excludes those IDs before decoding and keeps the concrete encrypted-event input. --- plugins/platforms/matrix/read_context.py | 72 ++++++---------------- plugins/platforms/matrix/thread_context.py | 69 ++++++++++++++------- tests/gateway/test_matrix_read_context.py | 3 +- 3 files changed, 69 insertions(+), 75 deletions(-) diff --git a/plugins/platforms/matrix/read_context.py b/plugins/platforms/matrix/read_context.py index 64e4cfd37cd4e..acc5b4394b3df 100644 --- a/plugins/platforms/matrix/read_context.py +++ b/plugins/platforms/matrix/read_context.py @@ -3,24 +3,17 @@ from __future__ import annotations import asyncio -from enum import Enum from typing import Any from urllib.parse import quote from plugins.platforms.matrix.relations import MatrixRelation -from plugins.platforms.matrix.reply_context import ( -

The gateway already records its loop in `GatewayRunner._gateway_loop`. `_set_session_env` now passes that loop as `transport_loop`, and other callers bind no loop. The read tool scheduled its coroutine with its own schedule-and-close code, and it awaited the read without a deadline when the handler ran on the gateway loop itself. It now uses `safe_schedule_threadsafe`, which closes the coroutine when scheduling fails, and every read goes through the same deadline. The handler also accepted a `room_id` argument that the schema does not declare. Reads always use the session's room, so the argument is gone. --- gateway/run.py | 1 + gateway/session_context.py | 8 +-- tests/gateway/test_matrix_read_context.py | 12 +++-- tests/tools/test_matrix_read_tool.py | 63 +++++++++++------------ tools/matrix_read_tool.py | 42 +++++++-------- 5 files changed, 60 insertions(+), 66 deletions(-) diff --git a/gateway/run.py b/gateway/run.py index 17d9c458c10e2..c105ab8455209 100644 --- a/gateway/run.py +++ b/gateway/run.py @@ -4225,6 +4225,7 @@ def _set_session_env(self, context: SessionContext) -> list: profile=getattr(context.source, "profile", "") or "", async_delivery=_async_delivery, transport_adapter=_adapter, + transport_loop=getattr(self, "_gateway_loop", None), cron_session="") def _clear_session_env(self, tokens: list) -> None: diff --git a/gateway/session_context.py b/gateway/session_context.py index a1d2dfb3f81e0..5d1ab1b7a0d90 100644 --- a/gateway/session_context.py +++ b/gateway/session_context.py @@ -126,6 +126,7 @@ def set_session_vars( ui_session_id: str = "", cron_session: Any = _UNSET, parent_chat_id: str = "", session_history_delivery: str | None = None, transport_adapter: Any = None, + transport_loop: Any = None, ) -> list: """Set all session context variables and return reset tokens.

Any other transport gets the same "Matrix reads require a live Matrix session" error as a session on another platform. --- tests/tools/test_matrix_read_tool.py | 18 +++++++++++++++--- tools/matrix_read_tool.py | 7 +++---- 2 files changed, 18 insertions(+), 7 deletions(-) diff --git a/tests/tools/test_matrix_read_tool.py b/tests/tools/test_matrix_read_tool.py index 1bfe6eb9d31f6..252635c0e098e 100644 --- a/tests/tools/test_matrix_read_tool.py +++ b/tests/tools/test_matrix_read_tool.py @@ -9,6 +9,7 @@ import pytest +from gateway.relay.adapter import RelayAdapter from gateway.session_context import ( clear_session_vars, get_session_transport, @@ -76,10 +77,21 @@ async def test_matrix_read_uses_session_owner_and_room(): ) -def test_matrix_read_requires_live_matrix_session(): - tokens = set_session_vars(platform="cli", chat_id="!room:server") +@pytest.mark.asyncio +@pytest.mark.parametrize( + "session", + [ + {"platform": "cli", "transport_adapter": None}, + {"transport_adapter": object.__new__(RelayAdapter)}, + ], + ids=["cli", "relay-fronted-matrix"], +) +async def test_matrix_read_requires_live_matrix_session(session): + tokens = _bind_matrix_session(None, **session) try: - raw_result = registry.dispatch("matrix_read", {"kind": "room"}) + raw_result = await asyncio.to_thread( + registry.dispatch, "matrix_read", {"kind": "room"} + ) assert isinstance(raw_result, str) result = json.loads(raw_result) finally: diff --git a/tools/matrix_read_tool.py b/tools/matrix_read_tool.py index ce63dc21d95a3..2ccf1340bab73 100644 --- a/tools/matrix_read_tool.py +++ b/tools/matrix_read_tool.py @@ -18,11 +18,12 @@ async def _matrix_read(args: dict[str, Any]) -> str: room_id = get_session_env("HERMES_SESSION_CHAT_ID") requester = get_session_env("HERMES_SESSION_USER_ID") adapter, owner_loop = get_session_transport() + read_context = getattr(adapter, "read_matrix_context", None) if ( get_session_env("HERMES_SESSION_PLATFORM") != "matrix" or not room_id or not requester - or adapter is None + or not callable(read_context) ): return json.dumps({"error": "Matrix reads require a live Matrix session"}) @@ -44,9 +45,7 @@ async def _matrix_read(args: dict[str, Any]) -> str: if owner_loop is None or not owner_loop.is_running(): return json.dumps({"error": "Matrix gateway loop is unavailable"}) future = safe_schedule_threadsafe( - adapter.read_matrix_context( - kind, room_id, event_id, limit, requester=requester - ), + read_context(kind, room_id, event_id, limit, requester=requester), owner_loop, logger=logger, log_message="matrix_read: failed to schedule on the gateway loop", From 878e49eaaa91f2bff45905409c9df86bd5ada6cb Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Tue, 29 Sep 2026 18:55:08 +0100 Subject: [PATCH 78/87] fix(matrix): list Matrix reads oldest first Room and thread reads request history with `dir=b`, so the server returns the newest event first. Room reads returned that order unchanged, and thread reads put the root before the replies in reverse order (`$root, $r3, $r2, $r1`). A model that reads a thread as a conversation would take the oldest reply for the latest one. The thread backfill already reverses the relations chunk into chronological order. Reverse the chunk for both kinds. A room read now lists the latest messages oldest first, and a thread read lists the root followed by its latest replies, oldest first. The tool schema states the order, and that a thread read counts the root towards `limit`. Maintenance-adaptation: The read-policy recheck uses the adapter's synchronous room predicate after identity lookup. Preserve the actual predicate binding and empty default allowlist when consolidating the existing inline adapter doubles into this factory. The original overrides, read assertions and parameter rows remain unchanged. --- plugins/platforms/matrix/read_context.py | 73 ++++--- tests/gateway/test_matrix_read_context.py | 243 +++++++++++----------- tools/matrix_read_tool.py | 7 +- 3 files changed, 168 insertions(+), 155 deletions(-) diff --git a/plugins/platforms/matrix/read_context.py b/plugins/platforms/matrix/read_context.py index acc5b4394b3df..a287d612de8c8 100644 --- a/plugins/platforms/matrix/read_context.py +++ b/plugins/platforms/matrix/read_context.py @@ -46,6 +46,18 @@ async def _visible_event( } +async def _thread_root( + client: Any, room_id: str, event_id: str +) -> dict[str, Any] | None: + try: + root = _raw_event( + await asyncio.wait_for(client.get_event(room_id, event_id), timeout=10.0) + ) + except Exception: + return None + return root if root.get("event_id") == event_id else None + + async def read_matrix_context( adapter: Any, kind: str, @@ -74,35 +86,24 @@ async def read_matrix_context( if client is None: return {"error": "Matrix client is disconnected"} -

In a busy room, `limit: 5` could return one message or none, and the result did not say that events had been dropped. An event read of a reaction, a state event or a redacted message returned an empty list with no error, which looked like a successful read of nothing. Room reads now send a `filter` that limits the timeline to `m.room.message`, `m.room.encrypted` and `m.sticker`, so `limit` counts candidate messages. Results include `skipped`, the number of events in the read window without a readable body, such as redacted messages. An event read of an event without message content returns an error. The live read test now also reads the room through Synapse. It checks that the server accepts the filter, that the events are oldest first and that none are skipped. --- plugins/platforms/matrix/read_context.py | 19 ++++- tests/gateway/test_matrix_read_context.py | 76 ++++++++++++++++++- .../matrix_live/test_read_tools.py | 38 +++++++++- tools/matrix_read_tool.py | 4 +- 4 files changed, 126 insertions(+), 11 deletions(-) diff --git a/plugins/platforms/matrix/read_context.py b/plugins/platforms/matrix/read_context.py index a287d612de8c8..886dd01f9fbaa 100644 --- a/plugins/platforms/matrix/read_context.py +++ b/plugins/platforms/matrix/read_context.py @@ -3,6 +3,7 @@ from __future__ import annotations import asyncio +import json from typing import Any from urllib.parse import quote @@ -14,6 +15,10 @@ history_message, ) +_MESSAGE_FILTER = json.dumps({ + "types": ["m.room.message", "m.room.encrypted", "m.sticker"] +}) + def _raw_event(event: Any) -> dict[str, Any]: if isinstance(event, dict): @@ -113,7 +118,12 @@ async def read_matrix_context( "error": "Matrix history is unavailable until the first sync completes" } path = f"/_matrix/client/v3/rooms/{room}/messages" -

Tool resolution also treated the non-configurable toolset as native to Matrix and added it to every Matrix toolset list, including a saved list of individual toolsets. Only `agent.disabled_toolsets` could remove it. Add `matrix_read` to `CONFIGURABLE_TOOLSETS` and restrict it to Matrix in `_TOOLSET_PLATFORM_RESTRICTIONS`, as for the Discord toolsets. The Matrix checklist and the enable and disable commands now offer it, and other platforms reject it. An unsaved Matrix configuration and a saved `[hermes-matrix]` list still enable it through the composite. A saved list of individual toolsets enables it only when it lists `matrix_read`, so a list saved before this toolset existed leaves it off until the user enables it. The toolsets reference lists `matrix_read`, and the Matrix guide describes the tool and how to turn it off, where it previously said that Hermes has no Matrix-specific agent tools. --- hermes_cli/tools_config.py | 1 + hermes_cli/toolset_scope.py | 6 +- tests/hermes_cli/test_tools_config.py | 65 ++++++++++++++++++++ website/docs/reference/toolsets-reference.md | 3 +- website/docs/user-guide/messaging/matrix.md | 6 +- 5 files changed, 78 insertions(+), 3 deletions(-) diff --git a/hermes_cli/tools_config.py b/hermes_cli/tools_config.py index 2bf2b5101b50a..d7bba0948167b 100644 --- a/hermes_cli/tools_config.py +++ b/hermes_cli/tools_config.py @@ -90,6 +90,7 @@ def install_cua_driver(*args, **kwargs) -> NoReturn: ("spotify", "🎵 Spotify", "playback, search, playlists, library"), ("discord", "💬 Discord (read/participate)", "fetch messages, search members, create thread"), ("discord_admin", "🛡️ Discord Server Admin", "list channels/roles, pin, assign roles"), + ("matrix_read", "📜 Matrix History", "read room, thread and event history"), ("yuanbao", "🤖 Yuanbao", "group info, member queries, DM"), ("computer_use", "🖱️ Computer Use (macOS/Windows/Linux)", "background desktop control via cua-driver"), ] diff --git a/hermes_cli/toolset_scope.py b/hermes_cli/toolset_scope.py index 78adf0e4949ac..9da3d7d7a344b 100644 --- a/hermes_cli/toolset_scope.py +++ b/hermes_cli/toolset_scope.py @@ -4,7 +4,11 @@ #

On Matrix the gateway's tool_progress default is "new", so the second turn also sends a progress message such as '⚙️ tool_search: "Searching tools · Matrix read event"' as m.text when the tool loop starts. That message usually reaches the observer after the fake model has already answered every request. On a heavily loaded runner the model loop can finish later than the progress message arrives, so the test stopped waiting early and failed with `assert 4 == 5` model requests. Wait instead for a bot message whose body is the expected reply: "Matrix live reply" for the first turn and "Read complete" for the second. Progress messages no longer end the wait, and the test does not depend on the platform's display defaults. Delaying the fake model's second response in that turn by 3 seconds reproduces the failure on the old test (`assert 3 == 5`, with the progress message accepted as the reply). The new test passes with the same delay. Live Matrix request/reply waits cover real HTTP sends, text batching, and the first gateway turn. A cold-service exchange produced a valid reply after 21.981 seconds, beyond the previous 15-second bound. Use the fixture's existing 60-second wait bound and keep the complete thread, reply and model-context assertions. --- tests/integration/matrix_live/test_read_tools.py | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/tests/integration/matrix_live/test_read_tools.py b/tests/integration/matrix_live/test_read_tools.py index 0c8b74af89e35..8e024266a8400 100644 --- a/tests/integration/matrix_live/test_read_tools.py +++ b/tests/integration/matrix_live/test_read_tools.py @@ -20,11 +20,10 @@ def test_model_reads_an_event_and_the_room_from_its_live_matrix_session( ) -> None: async def exchange() -> None: client = live_room.observer.client(live_room.homeserver) - seen: set[str] = set() try: await asyncio.wait_for(client.sync(timeout=0), timeout=60) - async def send_and_wait(body: str) -> str: + async def send_and_wait(body: str, reply: str) -> str: sent = await client.room_send( live_room.room_id, "m.room.message", @@ -41,13 +40,13 @@ async def send_and_wait(body: str) -> str: if ( isinstance(event, RoomMessageText) and event.sender == live_room.bot.user_id - and event.event_id not in seen + and event.body == reply ): - seen.add(event.event_id) return sent.event_id target = await asyncio.wait_for( - send_and_wait("Read target [history:blue]"), timeout=60 + send_and_wait("Read target [history:blue]", "Matrix live reply"), + timeout=60, ) gateway.model.push( ToolCall("tool_search", {"queries": ["Matrix read event"]}), @@ -76,7 +75,8 @@ async def send_and_wait(body: str) -> str: Text("Read complete"), ) await asyncio.wait_for( - send_and_wait("Read the earlier Matrix event"), timeout=60 + send_and_wait("Read the earlier Matrix event", "Read complete"), + timeout=60, ) requests = gateway.model.main_requests() From f78103268f25e2bfbd1ab8595edab180fd41b384 Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Wed, 30 Sep 2026 10:03:26 +0100 Subject: [PATCH 83/87] test(matrix): start the read deadline only once the stalled read runs test_matrix_read_deadline_cancels_a_stalled_read failed on a loaded runner with a TimeoutError from its two-second wait for the stalled read to finish. The tool schedules the read on the gateway loop with run_coroutine_threadsafe and starts its deadline straight away in the worker thread. In this test the gateway loop is the test's own event loop, and the deadline was 0.05 s. When that loop did not run within the deadline, the worker cancelled the concurrent future before the loop had created the read task. The task was then cancelled before its first step, so the body of the fake read never ran. It recorded no outcome and never set the event that the test was waiting for, and no amount of waiting would have set it. The test now wraps safe_schedule_threadsafe so the worker thread waits until the fake read is waiting for its release before the tool applies the deadline. The deadline is 0, so it expires as soon as the tool awaits the read and the passing path uses no timer. The other waits are on events. A ten-second timeout on the dispatch remains. Once the read has started, the tool needs only a few steps of CPU work to return, so in practice only a tool without a deadline reaches that timeout. The test then releases the read and fails on its assertion, so it does not hang until the runner's file timeout. Blocking the test's event loop for 0.5 s after starting the dispatch reproduces the logged TimeoutError with the old test, and the new test passes with the same delay. With the deadline removed from the tool, the new test fails after about 12 seconds. --- tests/tools/test_matrix_read_tool.py | 25 ++++++++++++++++++++++--- 1 file changed, 22 insertions(+), 3 deletions(-) diff --git a/tests/tools/test_matrix_read_tool.py b/tests/tools/test_matrix_read_tool.py index 2f070c645b571..09a47b649050c 100644 --- a/tests/tools/test_matrix_read_tool.py +++ b/tests/tools/test_matrix_read_tool.py @@ -193,12 +193,27 @@ async def test_matrix_read_refuses_a_stopped_owner_loop(): @pytest.mark.asyncio async def test_matrix_read_deadline_cancels_a_stalled_read(monkeypatch): - monkeypatch.setattr(matrix_read_tool, "_READ_DEADLINE_SECONDS", 0.05) + monkeypatch.setattr(matrix_read_tool, "_READ_DEADLINE_SECONDS", 0) + owner_loop = asyncio.get_running_loop() + reading = asyncio.Event() release = asyncio.Event() settled = asyncio.Event() outcome = [] + schedule = matrix_read_tool.safe_schedule_threadsafe + + # A read cancelled before the gateway loop starts it never runs, so the + # deadline must not begin until the read is waiting. + def schedule_and_wait_until_reading(*args, **kwargs): + future = schedule(*args, **kwargs) + asyncio.run_coroutine_threadsafe(reading.wait(), owner_loop).result() + return future + + monkeypatch.setattr( + matrix_read_tool, "safe_schedule_threadsafe", schedule_and_wait_until_reading + ) async def stalled_read(*args, **kwargs): + reading.set() try: await release.wait() outcome.append("completed") @@ -214,12 +229,16 @@ async def stalled_read(*args, **kwargs): dispatch = asyncio.create_task( asyncio.to_thread(registry.dispatch, "matrix_read", {"kind": "room"}) ) - await asyncio.wait({dispatch}, timeout=2) + started = asyncio.create_task(reading.wait()) + await asyncio.wait({dispatch, started}, return_when=asyncio.FIRST_COMPLETED) + started.cancel() + await asyncio.wait({dispatch}, timeout=10) release.set() raw_result = await dispatch assert isinstance(raw_result, str) result = json.loads(raw_result) - await asyncio.wait_for(settled.wait(), timeout=2) + if reading.is_set(): + await settled.wait() finally: clear_session_vars(tokens) From c8a0fb4fcce458d4bd94490fc6b28243c762f611 Mon Sep 17 00:00:00 2001 From: Iain Lane Date: Thu, 1 Oct 2026 13:47:09 +0100 Subject: [PATCH 84/87] fix(matrix): require a target for thread and event reads The read adapter accepts an optional event ID because room history does not need one. Thread reads nevertheless passed None to get_event, and event reads did the same before reporting missing content. The tool validates its arguments, but the shared adapter interface did not enforce its own targeted-read contract. Reject a missing target before requesting history. Resolve a thread root only within the branch that has a target. Both targeted modes now return an actionable error without a network request, and the thread lookup has an explicit string argument. Both regression cases fail on the preceding implementation.

The general SDK Event factory dispatches back to EncryptedEvent for this input, but its dynamically assigned deserialize attribute is absent from the SDK's static Event type. Use EncryptedEvent.deserialize with the SDK's JSON input type directly. This retains the same runtime decoder while expressing the known event kind to the type checker. Update the isolated read fake to provide that concrete decoder. The real-SDK encrypted reply and thread contracts still exercise available and missing decryption keys. This correction is folded into the shared decoder introduction, original source 9a1d890f3583e28dece703928d5c4e4fe6e307d5.

Preserve the supplied session in the fake API. Use a wrapping disconnect spy in the reconnect test and disconnect the replacement client after the existing call assertion. The fake API and reconnect fixture predate this branch, so this focused fixture maintenance is separate from the corrections folded into their campaign contributors. Production code and all original assertions are unchanged. Current published supplier fixture compatibility The current read-tools supplier has the same fake HTTP API session and reconnect lifetime defects. Preserve the complete existing test module and every assertion. Reuse the already published client factory from the final credited maintenance scope so each fake Client exposes the actual API session. Only the fourteen existing fake Client assignments are adapted, and the canonical-ID reconnect fixture disconnects its first connection before opening the second; production and the retained eighty-five contributor records remain unchanged. --- tests/gateway/test_matrix.py | 49 ++++++++++++++++++++++-------------- 1 file changed, 30 insertions(+), 19 deletions(-) diff --git a/tests/gateway/test_matrix.py b/tests/gateway/test_matrix.py index d2db76171fb15..e23244cf4caf2 100644 --- a/tests/gateway/test_matrix.py +++ b/tests/gateway/test_matrix.py @@ -12,6 +12,15 @@ from gateway.turn_context import TurnContext +def _client_factory(client): + class Client: + def __new__(cls, **kwargs): + client.api = kwargs["api"] + return client + + return Client + + def _make_fake_mautrix(): """Create a lightweight set of fake ``mautrix`` modules. @@ -32,8 +41,10 @@ class HTTPAPI: def __init__(self, base_url="", token="", **kwargs): self.base_url = base_url self.token = token -
