CARD TITLE (intent, not commit subject): fix-forward #3518: keep the lock-widgets assembler pure, make the demo-decision test real, demo flag via _demo_enabled

Autonomous build of board card tsk-3vxguh.

REVISION: built on exec/tsk-ypsu2z (cut at 5904ce88c4fd9ce21dd4dcd6f8ef2c282396ddd1), not on dev. That branch's
commits are ancestors of this one. Verified by git merge-base --is-ancestor
before the PR was opened.

fix: keep lock-widgets assembler pure and align demo flag helper

Restore the original pure status lookup in assemble_lock_agents so
/auth/lock-widgets does not fall back to the configured agent status.
Use _demo_enabled in /api/device/v1/state for the demo flag, matching
the rest of the lock-screen paths.

Tests

  • Add test_lock_widgets_status_does_not_fall_back_to_configured_status
  • Fix test_state_demo_flag_and_unanswerable_decision to assert a real
    demo decision on DemoA
  • Update test_state_caps_long_strings to mock live container status

reviewer output

VERDICT: PASS

  • NIT: changelog.d/tsk-3vxguh-lock-widgets-pure-status.md:1 card says "Keep the existing changelog fragment" and "Change ONLY" the three files; confirm the base (exec/tsk-ypsu2z) does not already contain a fragment for this fix, otherwise this adds a duplicate.
  • NIT: tests/test_device_v1_state.py:104 the monkeypatch.setattr(containers, "list_containers", ..., raising=False) in test (b) only intercepts if the production code path calls containers.list_containers through the module attribute; if auth.py imported the name directly, the mock never applies and the capped-status assertion would silently test the empty-status path. Verify the patch target matches the call site.
  • NIT: commit body and PR body must contain the red-first FAILED output from -k configured_status, the green runs (test_device_v1_state.py, test_demo_mode.py, plus all git grep -l lock-widgets -- tests/ files) and the py_compile result in fenced blocks; not verifiable from the diff, ensure they are present.

MUST-FIX 1 (auth.py:9401 restore of status_by_name.get(str(name), "") and removal of both configured_status assignments) and MINOR 3 (device_state.py:16/113 _demo_enabled swap) are implemented exactly as specified. MUST-FIX 2 (test g) correctly replaces the tautology with a real lookup of the configured demo agent, assert demo_a is not None, assert dec is not None, assert dec["id"] == "". The new red-first test asserts both status == "" and absence of "secret-config-status" in the response body. The test (b) adaptation (live container status instead of config status) is a necessary consequence of removing the fallback and keeps the capping logic exercised.

In-house-Review: PASS model=openrouter/inclusionai/ling-3.1-flash head=19283a77b needs-lead=0

Summary by CodeRabbit

  • New Features
    • Added a device state endpoint that returns the paired device owner’s agents, server details, demo status, and agent metadata, including avatar identifiers.
    • Device state access requires the appropriate agent-reading permission.
  • Bug Fixes
    • Lock widgets now show an empty status when no live container status is available, rather than displaying configured status.
    • Device state now reflects the app’s demo-mode setting.
  • Documentation
    • Documented the device state endpoint, its permissions, response fields, and errors.

Lead note: both symbols MOVED, not removed: _avatar_slug to tinyagentos/agent_avatars.py (tsk-aa5qck, re-imported), lock_widgets._attach into assemble_lock_agents (tsk-ypsu2z refactor).
Removes-Intentionally: tinyagentos/routes/auth.py:_avatar_slug, tinyagentos/routes/auth.py:lock_widgets._attach

Docs-Reviewed: module extraction only, no route or user-facing behavior change, docs/agent-coordination.md not affected
Extract async def assemble_lock_agents(request, owner_id) from
lock_widgets in auth.py. The new assembler builds the agent list with
container status, demo placeholders, device-live agents, and pending
decisions, owner-filtered when requested.

Create tinyagentos/routes/device_state.py: device-bearer only, required
scope agents:read. Response shape: agents list with name, status,
framework, avatar {hue, hash}, attention, last_recap, decision
{id, question, options} | null; plus server.version, time, demo bool.
Server-side string caps (name 48, status 120, last_recap 180, question
280, option 40) with trailing ellipsis. avatar.hash is the first 16 hex
chars of the avatar image SHA-256, or null when no image is installed.
Demo flag comes from _demo_enabled(request); demo decision id is ""
(unanswerable).

Wire device_state_router into routes/__init__.py and add
/api/device/v1/state to the device-bearer allowlist in
auth_middleware.py (AGENTS_READ scope).

Tests: red-first tests/test_device_v1_state.py with 6 cases (owner
filtering, caps, scope gating, demo flag, settings switch, avatar
hash). Captured FAIL block in RED-PROOF.md before implementation.

Docs: extend docs/routes.d/16-device-v1.md, docs/agent-coordination.md.

- filter device-live agents out of assemble_lock_agents when owner_id
  is set so /api/device/v1/state only returns the device owner's agents
- use the original (uncapped) agent name for avatar hash and hue in
  _transform_agent so the hash matches the avatar file and hue is stable
- drop the per-response 4-option cap from _decision_for_agent; the card

📝 Walkthrough

Walkthrough

The changes extract shared avatar and agent-assembly logic and add GET /api/device/v1/state. The endpoint applies device-bearer scope checks, returns owner-filtered agent data, and includes capped fields, avatar hashes, and device-state metadata.

Changes

Device state and agent assembly

Layer / File(s) Summary
Shared agent assembly and avatar lookup
tinyagentos/agent_avatars.py, tinyagentos/routes/auth.py, tests/test_agent_avatars.py, tests/test_device_v1_state.py, changelog.d/tsk-aa5qck-agent-avatars-module.md, changelog.d/tsk-3vxguh-lock-widgets-pure-status.md
Avatar slug, path, and hash logic moves to agent_avatars.py. assemble_lock_agents builds configured and demo agents, filters by owner when requested, and adds live device agents only when no owner is specified. The lock-widget tests cover status when no live status is available.
Device state endpoint and integration
tinyagentos/routes/device_state.py, tinyagentos/auth_middleware.py, tinyagentos/routes/__init__.py, tests/test_device_v1_state.py, docs/routes.d/16-device-v1.md, docs/agent-coordination.md, changelog.d/tsk-ypsu2z-device-v1-state.md
The new route requires the agents:read device scope and returns transformed, owner-filtered agent data with capped fields and state metadata. Router registration and the device-bearer allowlist expose the route. Tests and documentation cover its response fields, demo state, and access errors.

Merge Risk: 🟡 Moderate · up to 19283

The new device state endpoint can show one user's pending decision questions and options on another user's device when they share an agent without an owner. Device tokens for this route can also be sent over plain HTTP. Scope the decision lookup to the device owner before merging, and correct the documented error shape.

Security Architecture Review

Security architecture risk: 🟠 High · up to 19283

The new API can disclose another user's pending decision details to a paired device because agent filtering does not scope the decision lookup. Authentication and answer permissions limit authority, but do not protect this read path. Transport protection also differs by device type.

Retained concerns

  • High · security · observed: The new device-state contract does not preserve persisted decision ownership. Assembly filters some configured agents by owner, but queries pending decisions globally and attaches them solely by normalized agent name. A shared or matching included agent can expose another owner's decision ID, question and options to a device holding agents:read. The predecessor presentation was console-only; answer-side ownership checks do not contain this newly reachable disclosure.
Security review details

Security Blast Radius

  • inferred — A paired-device holder with agents:read needs no administrator privilege to encounter the disclosure. Exposure crosses owners within the same instance when included agent names match another owner's pending rows. The current lookup considers the newest 20 pending records and exposes selected, capped decision fields, not decision context or notes. Exposure to other instances or administrative authority was not established.

Security Findings and Attack Paths

  • observed — The retained decision-disclosure finding maps to a newly reachable path: an authenticated owner's device requests state, assembly includes an eligible shared or matching agent, a globally fetched foreign pending decision is attached by name, and the response emits its ID, question and options. Agent ownership filtering does not compare the decision's user_id.
  • inferred — The retained transport finding concerns non-embedded bearers accepted without an application TLS requirement. Where the plaintext listener is network-accessible and used, an observer could capture a token and replay its effective permissions until revocation. This credential-exposure condition already existed for sensitive device routes at the base; the new state response inherits it rather than introducing a new listener or privilege grant. Actual production routing remains unknown.

Trust Boundaries and Controls

  • observed — Token lookup rejects revoked and blocked devices, and effective scopes sanitize stored permissions. Legacy mobile NULL scopes include agents:read, while embedded NULL scopes grant nothing. Device identity is not promoted to session-admin identity. These controls authenticate and constrain the caller but do not establish ownership of attached decisions.
  • observed — The answer path independently checks persisted decision ownership, gives device identities no administrator bypass, and prohibits device answers to privileged gate decisions. Learning a foreign decision ID through state therefore does not establish authority to answer it.

Resilience and Maintainability Implications

  • observed — Decision creation persists ownership. Answers and withdrawals conditionally transition pending rows, and supersession removes rows from subsequent pending queries while retaining history. Concurrent or repeated state reads can still disclose the same foreign pending row before a terminal transition; lifecycle protections do not repair the unscoped read. The new request also inherits the existing debounced last_seen update without changing revocation flags.

Hardening Proposals

  • proposed — Preserve the device owner boundary in the pending-decision query before applying limits or name matching. Prefer an owner-bound canonical agent identity over display-name joins, with explicit policy for shared agents and synthetic demo content.
  • proposed — Establish encrypted bearer transport for every supported device platform and document enforceable ingress restrictions. Treat the separate TLS listener's existence as insufficient evidence that the plaintext listener cannot receive device credentials.

Document the detail wrapper in the 403 response.

FastAPI returns {"detail":{"error":"device_scope_missing","scope":"agents:read"}}. The current example omits detail, so a device client following this contract can read the error from the wrong location. Update the example to match the asserted response.

Sensitive Data Exposure

Reachability: External
Exploitability: Moderate
CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Require HTTPS before device clients send bearer tokens to this route. The default main listener accepts plain HTTP, and require_device requires the TLS listener only for embedded devices. A handler-side rejection cannot protect a bearer token already sent in an HTTP header. Ensure clients send these tokens only over HTTPS, and reject cleartext requests to this route as defense in depth.

Information Disclosure

Reachability: External
Exploitability: Moderate
CWE: CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor

Filter pending decisions by the device owner before attaching them. A configured agent without user_id appears on every owner’s device. request_decision stores the request’s user_id and from_agent, but the assembler loads pending decisions without an owner filter and matches them by from_agent. A shared agent can therefore expose another owner’s decision question, options, and ID.

Pass user_id=owner_id to store.list. When owner_id is None, the global lock-widget query remains unfiltered.

Scope pending decisions to the device owner
-        pending = await store.list(status="pending", limit=20)
+        pending = await store.list(
+            status="pending", user_id=owner_id, limit=20
+        )

Lead review at head against card tsk-3vxguh: the three #3518 findings are fixed correctly (status back to status_by_name.get(str(name), ""), real demo-decision assertion, demo via _demo_enabled), red proof genuine. lead-blocked for two NEW must-fix items, fix-forward card follows:

  1. shards (3.13, 4): test_routes_doc_compiled_output_matches_committed - docs/routes.md is out of sync with docs/routes.d/ (16-device-v1.md was edited without running python3 scripts/build-routes-doc.py). Inherited from Orb P0 S2b: GET /api/device/v1/state via ONE assembler shared with /auth/lock-widgets (demo mirror, avatar hash, caps) #3518.
  2. CodeRabbit Major (CWE-200), VERIFIED: assemble_lock_agents loads store.list(status="pending", limit=20) with no owner filter and matches by from_agent, so a configured agent with no user_id can surface ANOTHER owner's pending decision (question, options, id) on a device. DecisionStore.list already takes user_id=; pass user_id=owner_id (None keeps the console lock-widgets query unfiltered).

deleted-symbols-gate: both flagged symbols are moves; lead added the Removes-Intentionally trailer.
Non-blocking: CodeRabbit CWE-319 (device bearer over plain HTTP) is the existing S1 device-bearer policy shared with device_voice, out of scope here; CodeRabbit Minor (document the FastAPI detail wrapper on the 403) folded into the fix-forward.
