A bit of confusion

After migrating the SQLite database from OpenWebUI to Open-Compose-Use, files appear to be displayed inline with a live preview (similar to artifacts). However, this live preview never actually shows up 🤔, even though all other AI functionalities are working properly.

contracts-lint: the asyncapi gate cannot install its tool, and its validation depends on a remote host

What

The asyncapi job in contracts-lint.yml has two independent defects. It is not a required context, so it has been failing without blocking anything — which is how both went unnoticed.

Defect 1 — the gate cannot install its own tool

Embed-token replay-binding on the broker north face (jti/nonce single-use, token-channel binding)

The Storage broker north face authenticates the data-plane client with a peer-minted signed embed token (NFR-SEC-82, exp <=120s). The short TTL caps the replay window but NFR-SEC-82 specifies no single-use binding: a token captured inside its TTL still verifies if replayed from another origin/browser.

Gap. No jti/nonce single-use enforcement, no token-channel (DPoP-style) binding. Threat-model row P4-S3 (docs/architecture/06-threat-model.md section 3.2) anchors NFR-SEC-82 + SEC-83 and recor

Layer 8: OpenAPI + Protobuf schema files (operator REST, SOAR revoke, session set-up)

Tracking the not-yet-built executable schemas named in docs/architecture/08-contracts.md §5: contracts/openapi/ (operator REST + SOAR revoke) and contracts/proto/ (session set-up + lease pull). Each lands as its own PR against the §1 surface inventory once its field-level shape is sourced.

tsx is shipped but never executed in the image test — and my probe for it failed in ways I could not diagnose from outside

The gap

tsx reaches the sandbox image (global install off package.json) and the image test verifies only that it is in PATH and that --version exits 0. Nothing executes a .ts file through it.

That gap matters more now: #425 removes ts-node because TypeScript 7 deletes the JavaScript API it consumes, leaving tsx as the only TypeScript runner the image ships. A runner nothing exercises is the same shape as the pandas/opencv gap closed in #422 — installed, built, green, and fir

Egress trust-edge: regulated-tier security review of credential_injector filter

Envoy's credential_injector filter and its OAuth2 extension carry an upstream maturity caveat (limited production burn-in, intended for trusted-on-both-ends paths), while a third-party LLM API is an untrusted upstream. The regulated-tier posture for relying on this filter is deferred pending a security review.

tests/test_filter.py: 7 tests assert a preview button the filter deliberately stopped emitting

tests/test_filter.py has 45 assertions and nothing collected it. Run for the first time, 8 fail: one is a real drift, seven are stale.

The real one is fixed separately: DOWNLOAD_BASE_URL and DOWNLOAD_SCOPE are defined on Filter.Valves and were absent from the module's VALVES: docstring block. test_every_valve_is_documented_in_docstring iterates the actual model_fields and caught it the first time it ever ran.

The other seven are the tests/patches shape again -- the test predates a deliberate c

tests/patches has rotted while unrun: 16 failures from a fixture predating the current patch anchors

tests/patches has never been executed by CI, and when run it fails: 16 failures and 2 errors across the six files.

The cause is a stale test fixture rather than a defect in the patches.

test_fix_large_tool_results.py builds a synthetic middleware.py and runs the real patch scripts against it. Several tests need fix_tool_loop_errors to apply first (a cascade dependency, line 411-412), and that patch refuses:

settings-wrapper serves both internal routes unauthenticated when API_KEY is unset, and silently

settings-wrapper serves both internal routes without authentication when API_KEY is unset, and it has no tests at all.

settings-wrapper/app.py:36-38:

def _check_auth(api_key: str = Header(None, alias="X-Internal-Api-Key")):
    if API_KEY and api_key != API_KEY:
        raise HTTPException(401, "Invalid API key")

API_KEY comes from os.getenv("API_KEY", "") at line 30, so an unset variable makes the guard a no-op. Exercised rather than read:

chat_id is substituted into the system prompt unvalidated, so a newline injects instructions

chat_id is substituted into the system prompt three times without validation, so a newline in it injects instructions the model reads as its own.

a tokens-URL header sends the deployment's internal key out, and brings a credential back in

The same independent-fallback shape as #605, in a second place, and this one has a return path as well as an outbound one.

docker_manager.py:305-306:

mcp_tokens_url     = current_mcp_tokens_url.get()     or MCP_TOKENS_URL
mcp_tokens_api_key = current_mcp_tokens_api_key.get() or MCP_TOKENS_API_KEY

Both ContextVars are set straight from request headers (mcp_tools.py:1358-1367, x-mcp-tokens-url and x-mcp-tokens-api-key) with no validation, and they are resolved independently:

a base-URL header redirects upstream calls while the deployment credential is still sent

A request header chooses the upstream host, while the credential sent to it can still come from the deployment. Setting one without the other is what makes this interesting.

docker_manager.py:544-547:

anthropic_key  = current_anthropic_auth_token.get() or ANTHROPIC_AUTH_TOKEN
anthropic_base = current_anthropic_base_url.get()   or ANTHROPIC_BASE_URL

x-user-email is interpolated into an upstream header value with no validation

x-user-email is taken from the request header with no validation and interpolated into a header VALUE that the guest passes to the upstream API.

docker_manager.py:599:

extra_env["ANTHROPIC_CUSTOM_HEADERS"] = f"x-openwebui-user-email: {user_email}"

user_email comes from mcp_tools.set_context_from_headers:1322, which does current_user_email.set(headers["x-user-email"]) -- no allow-list, no length cap, no character check. security.py validates chat_id and paths; it has no email rule at all

chat_id is sanitised for the container name and not for the host mount path

The same chat_id is sanitised on its way to the container NAME and not on its way to the host MOUNT PATH.

docker_manager.py:501 builds the name:

sanitized_id = re.sub(r'[^a-zA-Z0-9_.-]', '-', chat_id)
container_name = f"owui-chat-{sanitized_id}"

docker_manager.py:605 builds the path, from the raw value:

uploads_path = os.path.join(chat_data_path, "uploads")
outputs_path = os.path.join(chat_data_path, "outputs")

NFR-SEC-81: the upload path classifies by filename, so payload.exe.png reads as image/png

NFR-SEC-81 asks that the ingest path classify every uploaded body BY CONTENT -- magic-byte sniff plus declared media type -- and record the resolved type on the object's metadata before the object becomes mount-visible.

This repository's upload path classifies by FILENAME only.

computer-use-server/uploads.py:37-39 is the whole classifier:

The inbound half of NFR-COMP-27 is now armed (#554). The outbound half is not, and this records what it needs.

NFR-SEC-65: teardown is guest-driven 'sleep && kill 1' with no revoke, no scrub, no route drop

NFR-SEC-65 asks that teardown on the container tiers run a HOST-DRIVEN ordered finalizer: credentials revoked and writable surfaces scrubbed BEFORE the process tree is killed, and the outbound route dropped host-side even when the guest is unresponsive.

The shipped teardown is the inverse on both counts: it is guest-driven, and it is a kill with no finalizer at all.

Idle shutdown runs inside the guest. _reset_shutdown_timer (docker_manager.py: 798-830) execs a shell into the container ending i

NFR-SEC-49: one shared key is authentication, not per-action authorization -- and unset it allows all

NFR-SEC-49 asks the gateway to evaluate a deny-by-default policy keyed on (authenticated caller, tool name, action parameters) BEFORE dispatch, so a caller authorized for tool T cannot invoke a denied action variant of T.

What exists is authentication, not authorization, and the distinction is the whole requirement.

NFR-SEC-72: the eight enumerated lifecycle transitions exist in no contract

NFR-SEC-72 applies the NFR-SEC-45 audit contract to the system-initiated lifecycle transitions: secret inject/revoke, scrub, snapshot-create, restore, teardown, crash-sanitize, pool-claim. The split is by initiator, so operator-initiated privileged actions stay with SEC-45 and these eight are SEC-72's fixture, with neither overlap nor gap between them.

None of the eight is named anywhere. Grep across contracts/, computer-use-server/ and helm/ for pool-claim, crash-sanitize and snapshot-create r
