Closes #1209

Status

Implement: done Review: complete (2 rounds; ADR 0061 flip 519e2c0 verified by adr-flip-check) Hardware: deferred to the stack's final run (maintainer, 2026-11-03) Gate: waiting for the stack
Next: full slow lane on the stack top once the Mac is idle; then the maintainer decides the merge

Completion conditions (#327)

• An operator leases a device, installs an app on it, and saves it as a baseline. The lease ends. simlock baseline list shows it with its platform, model, OS, mode, version and size. — fast tests in feat(baselines): save, list and remove baselines from held leases #1235 (dispatcher, CLI); on real devices: e2e/slow-baseline.test.ts, written, not yet run (the stack's final hardware run)
• simlock lease --platform <platform> --baseline <name> is granted a device with that app installed. The agent installs nothing. — fast tests in feat(leasing): a lease names a baseline and gets a copy of it #1236; on real devices: e2e/slow-baseline.test.ts, not yet run (final hardware run)
• After that lease is released, the next lease naming the baseline gets a device with the app installed and without any file or setting the previous lease changed. — fast tests in feat(leasing): a lease names a baseline and gets a copy of it #1236 (fake driver copies); on real devices: e2e/slow-baseline.test.ts iOS and Android file steps, not yet run (final hardware run)
• A lease with no baseline never receives a device made from one, and a lease naming one never receives a plain device or another baseline's device, even while one sits idle. — feat(leasing): a lease names a baseline and gets a copy of it #1236 "devices never cross pools" test
• A --baseline with a model, OS, mode or image tag the baseline was not made for fails at once, naming the mismatch. An unknown name fails at once. A stale baseline fails at once, naming why. — feat(leasing): a lease names a baseline and gets a copy of it #1236 dispatcher and domain tests (BASELINE_MISMATCH, UNKNOWN_BASELINE, BASELINE_STALE)
• Saving under an existing name leaves running leases untouched, and the next lease gets the new version. — feat(leasing): a lease names a baseline and gets a copy of it #1236 replace tests (lease running, none running, request waiting)
• Removing a baseline that a lease is using is refused. Removing an unused one frees its disk and the idle devices made from it. — feat(baselines): save, list and remove baselines from held leases #1235 baseline.remove tests (BASELINE_IN_USE, idle devices deleted, source destroyed)
• On a Mac, a plain iOS lease of a kind that was leased before is granted without a factory first boot, and a plain Android reset loads no snapshot into a running emulator and never wipes. — iOS: e2e/slow-ios-smoke.test.ts passed at feat(ios): every simulator is a copy of a seed, and every virtual device serves one lease #1210's dedb9f8; Android: feat(android): every emulator is a copy of a seed, booted from its boot snapshot #1222 fast tests, real-device run pending (the stack's final hardware run)
• Through a gateway, a request naming a baseline only one worker holds is granted by that worker. One that no worker holds fails at once. simlock worker list shows each worker's baselines. — feat(gateway): route baseline lease requests to a worker that holds the baseline #1241 gateway dispatcher and routing tests, e2e/single-host-fleet.test.ts
• simlock status and simlock list --devices show which baseline and version a device came from. The console lists each worker's baselines. — feat(leasing): a lease names a baseline and gets a copy of it #1236 CLI tests; feat(ui): a Baselines page and a device's baseline #1245 e2e/console/baselines.spec.ts
• simlock nuke removes baselines and seeds with every other managed device, and simlock doctor lists them with their size. — feat(ios): every simulator is a copy of a seed, and every virtual device serves one lease #1210, feat(android): every emulator is a copy of a seed, booted from its boot snapshot #1222, feat(baselines): save, list and remove baselines from held leases #1235 nuke and doctor tests
• The same request field works over the unix socket, the HTTP API, MCP and the client, and through SIMLOCK_BASELINE; the website describes it with the baseline commands. — feat(leasing): a lease names a baseline and gets a copy of it #1236 CLI, HTTP, MCP and client tests; website pages checked by claims review in feat(baselines): save, list and remove baselines from held leases #1235 and feat(leasing): a lease names a baseline and gets a copy of it #1236

Walkthrough

The console adds a read-only Baselines page with formatted, paged baseline rows, gateway worker labels, and stale status. Baseline save, removal, and stale events invalidate baseline data, with polling as a fallback. Device drawers show a baseline name and version when available. The change also updates navigation, documentation, and automated coverage.

Suggested reviewers: leonardoxr

Severity of issue fixed: Low

Merge Risk: Low · up to 519e2

The new page can be difficult to read on tablets and may not distinguish identically named workers. These are bounded usability issues suitable for follow-up.

Security architecture risk: Minimal · up to 519e2

This adds read-only baseline visibility without adding permissions or device-management actions. The inspected authentication and cleanup controls remain in place, and no material security risk introduced by this change was identified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The metadata scope can include every worker represented by a gateway: the existing baseline-list contract returns worker-qualified entries. The console presents that existing scope; it does not add an API for reading baseline image contents or mutating devices.

Trust Boundaries and Controls

• observed — The new reads traverse the shared API client, which sends same-origin credentials and the current bearer token when present. Existing HTTP handlers authenticate requests and pass the resulting identity into dispatcher sessions; the new hook does not supply its own identity or bypass those handlers.

Resilience and Maintainability Implications

• observed — Ordinary connection loss can retain current-session display data. Checking, signed-out, and ended session states remove the live provider, whose cleanup disposes queries and the connection; query disposal clears cached data. These existing transitions also govern the new baseline view.

Full details: Title check

Explanation

The title "feat(ui): a Baselines page and a device's baseline" matches the main change. The changeset adds a console Baselines page (BaselinesScreen, routes, state, and model) and shows a device's baseline in the device drawer and DeviceRow. The title is specific and follows a conventional commit style.

Full details: Description check

Explanation

The description links issue #1209 and gives a detailed status for the Baselines work. It lists completion conditions, test commands, and a review summary. It describes the console Baselines page, the device drawer baseline fact, the sidebar placement, and the documentation updates, all of which appear in the changeset.

Full details: Linked Issues check

Explanation

The changes satisfy the coding requirements in [#1209]. They add /baselines, the Baselines sidebar route after Queue, baseline row mapping, sorting, formatting, stale status, pagination, and the No baselines. state. The page shows the Worker column only in gateway mode. Baseline events invalidate the query, and polling provides the fallback refresh. The device drawer shows Baseline only for baseline-backed devices. The PR adds model, event, page, route, and end-to-end tests. It also updates the worker and gateway documentation.

Full details: Out of Scope Changes check

Explanation

The changes stay within [#1209]. The added UI code, tests, navigation updates, event mapping, polling, and console documentation directly support the requested Baselines page and device drawer fact. The ADR status update documents the baseline architecture and does not change runtime behavior. The fleet pagination test update supports the added console route. No lease or device-management behavior changes are shown.

Full details: Docstring Coverage

Explanation

Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 10 functions across 16 files. (6 skipped: 6 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Follow-up Comments

Key baseline rows by worker ID.

35-35: Minor · Functional Correctness · Quick win

Key baseline rows by worker ID.

If two workers share a label and each has a baseline with the same name, workerOf produces the same display name for both. Line 35 then gives both rows the same key. DataTable uses that key as its row ID and React key, so updates can reuse the wrong row identity. Build the key from entry.workerId and entry.name; keep the label for display and sorting. The gateway already supplies the worker ID, and worker labels are not constrained to be unique. (raw.githubusercontent.com)

Review comment at @ui/src/model/baselines.ts at line 35:
Update the baseline row key to combine entry.workerId with entry.name instead of
the worker display label and name; keep the display label for rendering and
sorting.

Use the wide layout for Baselines.

38-45: Minor · Functional Correctness · Quick win

Use the wide layout for Baselines.

The table remains in its fixed multi-column layout from 768px through 1099px, where ten or eleven columns can be difficult to scan. This does not violate the 360px no-sideways-scroll requirement, but wide enables the intended labelled-row layout for tablet widths.

Suggested fix

           <DataTable
+            wide
             label="Baselines"

Update the Baselines DataTable in the component rendering page.rows to enable
its wide layout, preserving the existing label, columns, and other table props.

Show a distinguishing identifier when worker labels collide.

55-60: Minor · Functional Correctness · Quick win

Show a distinguishing identifier when worker labels collide.

Worker labels are not unique. When two gateway workers use the same label, the Worker column shows the same value for both workers and hides their IDs. Include the worker ID for duplicate labels so an operator can identify the worker that holds each baseline.

Suggested fix

 function workerOf(entry: BaselineEntry, workers: readonly WorkerView[]): string | undefined {
   if (entry.workerId === undefined) return undefined;
   const known = workers.find((worker) => worker.id === entry.workerId);
-  return known === undefined ? entry.workerId : workerName(known);
+  if (known === undefined) return entry.workerId;
+  const duplicateLabel =
+    known.label !== undefined &&
+    workers.some((worker) => worker.id !== known.id && worker.label === known.label);
+  return duplicateLabel ? `${workerName(known)} (${known.id})` : workerName(known);
 }
