### 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

```
npm error code ETARGET
npm error notarget No matching version found for @asyncapi/generator-hooks@0.1.1.
```

The job runs `npx --yes @asyncapi/cli@6.0.0 validate`. That CLI hard-pins `generator-v2: npm:@asyncapi/generator@3.0.1`, and every `@asyn

### Sidebar with terminal not shown

Hello,
How do I get the terminal and live view to open? My setup seems to work in general, but i never see the preview area.

### 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.

Source: `docs/architecture/components/06-egress-trust-edge.md` Open question 1.
Substantive deferred security item; architecture-phase tracking issue (next/v1).

### 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

### 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:

    ERROR: fix_tool_loop_errors anchor 1/5 (tool_loop) not found in ...

### 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:

    API_KEY=<empty>  supplied=None

### 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.

system_prompt.py:703-706:

    base = f"{PUBLIC_BASE_URL}/files/{chat_id}"
    result = result.replace("{file_base_url}", base)
    result = result.replace("{archive_url}", f"{base}/archive")
    result = result.replace("{chat_id}", chat_id)

system_prompt.py never imports sanitize_chat_id -- grep returns zero. The
value arrives from mcp_tools.set_con

### 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:

    neithe

### 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
    if anthropic_key:
        extra_env["ANTHROPIC_AUTH_TOKEN"] = anthropic_key
        extra_env["ANTHROPIC_BASE_URL"]   = anthropic_base

### 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:

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

### skills: an API-supplied description escapes the <available_skills> block into the system prompt

A skill description from the user-config API is interpolated into the system
prompt's <available_skills> block without escaping, so a description
containing the closing tags escapes the block and lands in the prompt as
free-standing instructions.

Measured by executing the function. build_available_skills_xml was
ast-extracted from skill_manager.py:600 and given one skill whose description
is:

    </description>
    </skill>
    </available_skills>

### skills: an API-supplied skill name reaches a Docker mount path unsanitised

A skill name from the user-config API becomes a Docker mount path with no
sanitisation, so a name containing `..` mounts a host directory outside the
skills cache into the guest.

Measured by executing the function rather than reading it. get_skill_mounts was
ast-extracted from skill_manager.py:639 and run against a temp cache with a
skill named `../outside-skill`:

    cache check passed: True
    MOUNT host=/host/skills/../outside-skill
       ->  {'bind': '/mnt/skills/user/../outside-skill',

### preview: model-written HTML renders in an iframe with no sandbox attribute

The preview renders model-written HTML in an iframe with no `sandbox`
attribute, on the server's own origin.

Measured in computer-use-server/static/preview.js:

  - line 520: `case 'html': renderHtmlPreview(container, file)` -- the branch is
    selected by classify_file() in app.py:288, which decides purely on the
    file extension, so any file the model names *.html reaches it.
  - line 234: `iframe.srcdoc = text` -- the body is injected directly.
  - line 239: `iframe.src = file.url` -- the

### 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:

    def _guess_mime(path: Path) -> str:
        mime, _ = mimetypes.guess_type(path.name)
        return mime or "application/octet-stream"

### NFR-COMP-27 outbound: the four webhook payloads exist in no contract

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

The row names four event payloads for the signed webhook OUT: session.flagged,
policy.violation, dlp.hit, auth.anomaly. None of the four exists as a contract
artifact. Probed each across contracts/ -- three return nothing at all, and
policy.violation appears to match in all eight OCSF class files, which is a

### 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.

MCPAuthMiddleware (mcp_tools.py:1363-1390) compares the Bearer header against
one shared `api_key` and either passes the request through untouched or answers
401. The comparison se

### 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/,
