   platform-independent test that exercises both certificate and keychain paths.
 - A changelog search conflated the stable and prerelease lines. Verify published
   package code before assuming a release contains the upstream patch.
+- The environment-browser checkout has no `.memory/` directory despite AGENTS guidance; use current source, existing design references, and the scoped browser parity document as implementation evidence.
+- t3code's browser spans profiles/import, recording, annotations, device emulation, and agent control across desktop/server/web. Track a source-backed feature matrix before porting; a navigation-only webview would silently miss the requested parity.
+- `npm ci` completed without Electron's macOS payload in this worktree; `node node_modules/electron/install.js` restored `Electron.app` before UI testing.
+- T3's hardcoded `source3` Playwright extraction points at a different bundle string in installed Playwright 1.62.1; locate the named generated module to preserve selector-engine parity.
+- Generated onboarding art had real alpha but a 1254px canvas despite the requested 1024px; normalize the final PNG to the repository's exact 1024px contract and validate its alpha.
+- System `java_home` has no registered JDK, but Android Studio's bundled JBR works for Gradle; use its `Contents/jbr/Contents/Home` and the existing Android SDK explicitly for focused mobile tests.
+- No physical iOS device is connected for this run, and repository guidance prohibits simulators. Generic iOS `build-for-testing` with signing disabled compiles the app/tests; actual XCTest execution remains a physical-device check.
+- Electron 43 emits the console-message payload on the event object; reading the legacy second argument as that payload threw during first navigation and blocked the test app behind an exception dialog. Use the current typed event and verify in real Electron, not just service mocks.
+
+- 2026-09-07: Native Browser views sit above renderer menus/dialogs. Presentation now observes visible overlays and serializes tab show/hide across remounts so delayed cleanup cannot hide the replacement view.
+- Renderer-only Playwright captures omit native WebContentsViews; use the exact worktree Electron.app with CUA for visual proof. Several installed Electron copies share a bundle ID, so resolve the full app path.
+- Streaming reveal briefly renders duplicate final message text; E2E assertions must target the visible transcript occurrence and independently check the scripted tool scenario completed.
+- Browser preflight exposed two existing source-contract mismatches in unchanged provider badges and button press-feedback tests. Keep that baseline distinct from browser regression results.
+- Responsive emulation letterboxes inside the native slot. Crop captures to the rendered viewport before translating annotation coordinates; using the full slot silently distorts vertical selections.
+
+## 2026-09-07 — Browser integration verification
+
+- Floating placement measured the workbench wrapper and covered the Environment close control. Measure the chat viewport and visible side surfaces; retain a normal pointer-click regression.
+- Approval summaries and tool admission both use browser policy helpers. Full-mode E2E misses Ask-mode summary errors; retain TypeScript validation and an actual approval-loop regression.
+- Reverting live styles during the preview debounce must still enqueue the restored desired state; comparing only the last completed key leaves an in-flight change applied.
+- Native visual verification exposed empty-chat composer overlap and CDP visible-size ownership. Reserve every composer and use `dontSetVisibleSize` so device emulation cannot override the measured native slot.
+- Browser tab titles and renderer selection can lag the main state response. E2E waits for `aria-selected`, closes the intended row, and canonicalizes URLs when finding the native guest.
+- Launching the shared Dev profile hit existing artifact/history recovery errors. Browser testing uses `build/browser-dev-profile/` with separate portable/user-data roots, copied provider setup, and a fresh workspace history.
+- Live browser test: agent tried `browser_open(file:///tmp/sample.html)` and received HTTP(S)-only rejection, then recovered with a Python server serving all of `/tmp` on port 8899. UI workspace `open_file` is not exposed to agent tools; add explicit local-preview guidance and a bounded file-preview route through existing tools, including intentional handling of user-requested files outside the workspace and server cleanup.
+
+## Browser lifecycle and progressive disclosure — 2026-09-08
+- An agent-created Python preview outlived its document. Verified the exact task-owned PID/start/cwd/port, terminated it, confirmed the HTML was absent, and removed its log. Managed exact-file previews now replace that fallback.
+- Review found queued actions could resume after human takeover, approvals could outlive page identity, and hover overlays could intercept semantic clicks. Added focused regression coverage and fixes. A cursor-cleanup review incorrectly read evaluate's isolated-world argument; the live cursor test caught the regression, and cleanup was restored to the creation context.
+- Progressive disclosure must install executable tools and update both outbound and durable-compaction budgets at a turn boundary. A setup-return wiring mistake was caught by TypeScript/review before Electron validation.
+- `tsx -e` uses CommonJS here and cannot load Pi's ESM-only export; use `node --import tsx --input-type=module` for measurement scripts.
+- Host preparation runs after a tool turn, and Pi journals an aborted assistant on Stop. Cancellation tests must reach that boundary and preserve its journal record; an abort rejection must not become a policy fault, while an independent host failure must still fail closed.
+
+- Electron main-process evaluation cannot dynamically import a module from the Playwright utility world. The delayed-acquisition regression uses `process.getBuiltinModule` and synchronizes builtin ESM exports so its filesystem gate actually reaches the production namespace import; restored in test cleanup.
+- Final dev restart exposed Browser mounting with a fabricated default workspace while workspace data loaded. Mount it only after the selected workspace exists; verify cold startup and the existing Environment/browser integration suites.
+
+## PR99 hosted CI follow-up — 2026-09-08
+- Diagnostics source scanning treated console calls in the serialized Playwright guest runtime as executable main-process logging. Use syntax-aware scanning with regression cases, retaining the reviewed-sink boundary.
+- Hosted CDP returned redacted object keys in a different order; the test incorrectly tied collision suffixes to boolean values. Verify distinct sanitized keys and preservation of both values without relying on enumeration order.
+
+- Pullfrog identified silent sensitive guest permissions and a workspace-wide local-preview origin. Restrict guest grants and serve exact pinned document/asset sets with distinct origins; keep declared workspace-file authorization while blocking unrelated siblings.
+- Ad-hoc `tsx -e` selected CommonJS and rejected the ESM-only Pi package exports. Use `node --import tsx --input-type=module` for token-estimate probes.
+- Matching-first input probing showed Chromium suppresses the duplicate injected keyDown, so a timing-only expectation could swallow the only physical event. Use Electron's native debugger-source flag for keyboard input, and interrupt unexpected repeats. Mouse-down/up omit this flag and retain a bounded documented collision fallback.
+- The next hosted Electron gate exposed immediate recording stop before the encoder produced a frame (both attempts). Validate recorder readiness instead of weakening the WebM assertion. Completed-job logs during an active run require the jobs/logs API; gh run view waits for whole-run completion.
+- Independent Chromium reproduction showed per-port preview cookies leaked to other localhost ports because cookies ignore ports. Replace cookies with native frame/origin-scoped request authorization, strip inherited headers and legacy cookies, and test redirects against a controlled server.
+
+## PR99 direct-preview follow-up — 2026-09-08
+- Exact-grant hardening left path-only Files/chat/terminal previews unable to load local sidecars. Derive a bounded static resource set for user-originated opens only, preserve strict explicit agent grants, and test the actual path-only entry point.
+- Static-discovery review found a sidecar symlink could target an excluded HTML/PDF, and same-content rewrites could reuse an older modification-time fingerprint. Reject canonical document targets and include pinned source metadata in grant identity.
+
+## 2026-09-04 — Queued composer controls
+
+- Pi harness queueSteer/queueFollowUp are not exposed through the foreground durable transcript path. Use Stop, a persistence barrier, and normal append for desktop Steer.
+- E2E TypeScript uses an older lib target; use reverse/find rather than Array.at in new test helpers.
+- Appearance persistence uses the `settings` envelope in settings.json; verify the preference from that envelope after relaunch.
+- Queue removal confirms durable append, not provider receipt. Wait for the exact provider request before asserting conversation history.
+- Joined actions need explicit square inner seams, shared outer squircle radii, visible focus overflow, and observable hover/focus tests.
+
+## 2026-09-06 — Settings and global Skills verification
+
+- Responsive Model Pad sizing must use the actual Settings scrollport and account for titles, controls, axes, legends, zoom, and scroll position.
+- Gate both skill inventory readers before and after asynchronous discovery, and recheck at execution time; disabled projection must cover inference, compaction, recall, Telegram queues, and every Bot catalog/edit surface.
+- Keep full tests and production builds sequential in one checkout because both build native helpers and concurrent runs can race over universal binaries.
+- Route Bot-scoped catalog identity end to end and isolate per-Bot iOS caches; Android has no persistent catalog cache.
+
+## 2026-09-08 — 0.39.0 four-PR integration
+
+- Zsh does not split scalar loop values by default; use explicit delimiters in pairwise merge probes so branch names are not accidentally concatenated.
+- Standalone green PRs still conflicted in shared settings, test registries, and UI fixtures. Assemble the exact combined stack and retain every feature's test registration before merging to main.

 ## Release model metadata
 
 models.dev may be contacted only by `npm run models:refresh`, the release refresh invoked by `npm run dist`, the scoped post-merge catalog workflow, or the user-initiated foreground **Update model catalogs** action in Settings → Providers. The live action may request only the fixed `https://models.dev/api.json` endpoint without credentials, cookies, prompts, chats, selections, custom endpoints, or a device identifier; its validated device-local cache is display-only and must never change runtime limits, routing, or selectable inventory. Never add a models.dev call to startup, normal development, unpacked builds, ordinary live-app reads, onboarding navigation, or background polling. Artificial Analysis data and credentials must never be bundled: the live Electron app may contact its fixed Free endpoint only after the user explicitly chooses Connect & fetch or Fetch latest with their own key, then reads the normalized device-local cache offline.

 - `GET /bot-favorites` and `PATCH /bot-favorites`: at most 20 unique, non-archived Bot IDs; update is whole-list replacement under `If-Match`, so membership and order change atomically. A replacement may omit archived Bots and may still edit unrelated active favorites, but adding an archived Bot returns `bot_archived`. No successful favorites response retains an archived Bot ID.
 - `GET /bot-conversations?cursor=…&query=…&botId=…&limit=…`: newest-first stable pages of at most 50 items, with a 200-scalar search query and 128-scalar cursor. Search is confined to Bot name/purpose, conversation title, and the bounded previews actually projected by the Mac. Every item has `updatedAt >= createdAt`. `canRespondToApproval: true` is valid only while `activityState` is `waiting_for_approval`; a waiting row may still be non-respondable when the paired device lacks authority.
 - `POST /bots/{botId}/chats`: open-or-create the Bot's one persistent chat. The frozen v1 response remains `201` and the operation identifier remains `createBotChat` for compatibility with shipped clients, even when the existing chat is returned. When it already exists, the Mac returns it unchanged and ignores creation-only provider/model input. When absent, an empty body inherits the Bot provider/model; otherwise one exact providerId/modelId pair is required, plus `Idempotency-Key`. Partial pairs never fall back. The creation pair must be currently available; an unavailable selection fails closed without fallback. The Mac injects the authoritative `botId` and hidden managed-home workspace; neither identifier is accepted in the body, and every successful response includes that authoritative `botId`. Concurrent calls and retries converge on the same chat. Legacy duplicate chats remain readable for recovery, but only the deterministic canonical chat is writable or projected in the Bot inbox.
-- `GET /bot-capabilities`: safe revisioned provider/model, image-input capability, file-scope, shell, connection/MCP, skill, and other-capability catalog plus the full notice status. `supportsImages` is explicit and unknown capability fails closed. The response never returns display copy that the client could mistake for authority.
+- `GET /bot-capabilities?botId=…`: safe revisioned provider/model, image-input capability, file-scope, shell, connection/MCP, skill, and other-capability catalog plus the full notice status. The optional, exact `botId` selects an authenticated existing Bot so its saved unavailable choices can remain visible; omitting it returns the generic creation catalog. Unknown, duplicate, malformed, empty, and overlong query values fail closed. `supportsImages` is explicit and unknown capability fails closed. The response never returns display copy that the client could mistake for authority.
+- The catalog’s additive `skillsEnabled` boolean defaults to `true` when omitted. When `false`, skill inventory discovery and incarnation reconciliation pause; target-Bot catalogs may retain that Bot’s authenticated saved skill IDs as unavailable choices. Clients may preserve or remove those saved choices during unrelated edits, but must not offer unavailable unselected skills as new choices. The Mac enforces exact saved ownership and per-chat narrowing, withholds skills from all runtime contexts, and restores unchanged selections when the global gate reopens. Invalid provided values fail decoding.
 - `PATCH /bots/{botId}/capabilities`: `If-Match` Full/Custom update with the exact current `catalogRevision`. Full requires `confirmedForeground: true` and may carry one exact provider/model pair; omitting both preserves the saved choice for compatibility with older clients, while supplying only one is invalid. Custom contains exactly one currently available provider/model pair plus only exact positive opaque selections from that catalog. Optional `visionModel` uses three-state semantics: omitted preserves the companion, `null` clears it, and an exact provider/model object sets it only when the catalog marks that model image-capable. A supplied pair becomes revisioned durable authority, changing either primary or companion fences active turns, and the canonical persistent chat mirrors only the primary model. An unavailable model remains visibly blocked and is never replaced by fallback.
 - `GET /chats/{chatId}/capabilities` and `PATCH /chats/{chatId}/capabilities`: authenticated authoritative inherit/Custom view, then an `If-Match` update carrying both the exact `catalogRevision` and `expectedBotPolicyRevision`. The server rejects policy drift or any selection outside the current Bot ceiling and returns the authoritative chat subset view.
 - `GET /bot-access-notice`: Mac-owned acknowledgement status for this paired device. This v1 client recognizes only `bot-full-access-v1`; an unknown future version fails closed until matching copy ships. `POST /bot-access-notice/acknowledgement` accepts only that exact version, `continue_full` or `customize_first`, `confirmedForeground: true`, and an `Idempotency-Key`. Local dismissal never acknowledges it.

 ## Scope and confidence
 
+For current reusable Aiden components and shape rules, follow the [design guide](design-guide.md). The observations below provide historical interaction inspiration.
+
 This audit covers the installed `/Applications/ChatGPT.app`, build `26.715.31925` (`com.openai.codex`). Although the app is displayed as ChatGPT, its package and renderer identify it as the current ChatGPT-branded Codex desktop product. The findings therefore mix classic Chat, Codex agent, project, review, browser, and terminal flows.

+# Aiden design guide
+
+## Reusable action shapes
+
+Use the shared `Button` from `renderer/components/ui.tsx` for actions, including
+icon-only controls and links rendered with `asChild`. Labeled and icon-only
+buttons use the same soft squircle shape. Choose the existing size and variant
+for emphasis; do not add a separate pill or circular button variant.
+
+| Surface | Reuse | Geometry |
+| --- | --- | --- |
+| Buttons, toolbar actions, navigation actions, and button links | `Button`, or the shared action rule in `renderer/styles.css` for existing native buttons | `--radius-button: 16px` and `corner-shape: squircle` |
+| A custom visual that must follow a button's silhouette, such as its artwork mask | `.squircle-control` | The same button radius and corner shape |
+| Joined actions, such as an action with a separate menu trigger | `.squircle-control.squircle-action-group` around direct `Button` children | 16px outer corners, square internal seams |
+| Chat composer | `.composer-shell` | `--radius-composer: 40px` and `corner-shape: squircle` |
+
+The renderer's action rule also covers existing `button`, `[role="button"]`, and
+`[data-slot="button"]` elements, including the compact dictation window. Reuse
+that rule instead of adding per-screen geometry. Radio indicators, checkboxes,
+and switch tracks retain their recognizable selection shapes. Text fields keep
+their existing field geometry and focus treatment.
+
+Use native CSS geometry in the Electron renderer. Keep shadows on the shaped
+element and preserve visible overflow for menus, badges, and focus rings. Apply
+clipping only to an inner artwork mask that needs it, never to the whole action
+or composer. No JavaScript path generation or new dependency is needed.
+
+Joined actions reuse the group rule instead of per-corner utility overrides.
+Their individual hover and focus fills meet at straight seams, while the group
+and its end buttons share the outer squircle. Leave the group overflow visible
+so each button's keyboard outline and portaled menus remain unobstructed.
+
+## Color, state, and accessibility
+
+Reuse semantic surface, text, accent, status, and elevation tokens from
+`renderer/styles.css` and `renderer/shared/appearance.ts`. Shape does not change
+an action's meaning: primary actions retain their accent, destructive actions
+retain their semantic treatment, and transparent actions gain a soft fill on
+hover. Avoid decorative borders and outlines.
+
+Preserve neutral `focus-visible` outlines on non-text controls, accessible labels
+for icon actions, disabled semantics, and existing hit-target sizes. Text-entry
+focus uses fill and caret changes without a new border or ring. Reuse existing
+hover and press feedback and respect Reduce Motion; do not animate the corner
+shape or add layout shifts.
+
+## Verification
+
+Check shared and custom actions in onboarding, the chat toolbar and composer,
+queued-message dialogs, Settings, and compact windows. Exercise hover, keyboard
+focus, disabled states, light and dark themes, narrow layouts, and overflow
+menus. The interactive [element specimen](chatgpt-ui-element-specimen.html)
+demonstrates the same geometry. Extend the button appearance contract and
+Electron interaction tests when these rules change.

+# Environment browser
+
+Open **Environment → Browser**. Tabs remain alive when another Environment tab is selected or the panel closes. The compact tab strip and navigation row follow the supplied desktop browser reference and use Aiden's appearance tokens.
+
+The browser is adapted from the local T3 Code reference. Its selector runtime is Playwright's injected runtime; notices are in `THIRD_PARTY_NOTICES.md` and `main/services/browser/PLAYWRIGHT-LICENSE`.
+
+## Controls
+
+| Surface | Behavior |
+| --- | --- |
+| Navigation | Tabs, address field, back/forward, reload/stop, hard reload, loading/failure state, favicon, mute, ten recent URLs per workspace, and detected terminal dev-server URLs. Recents and open tabs are kept in memory for the app session. |
+| Viewport | Fill, editable dimensions, the 17 reference device presets, rotation, ratio lock, drag handles, zoom, and system/light/dark page appearance. Presets change layout, not the browser user agent. |
+| Capture | Screenshot copy/save, recording start/stop with a local WebM artifact, a draggable/resizable browser over chat, and a separate picture-in-picture window. |
+| Profiles | Default, memory-only Incognito, and named persistent profiles. Profile changes apply to new tabs. Cookies/cache can be cleared separately. |
+| Cookie import | Explicit one-time import from supported locally discovered browsers. Quit the source browser first. Import copies cookies only, skips unsupported partitioned/encrypted records, and reports partial results. Safari requires the OS file permission. |
+| Links/files | Chat and terminal web links follow Browser settings; Cmd/Ctrl-click opens the system browser. Files offers Open in Browser for HTML/PDF. A scoped loopback server serves approved workspace documents and web assets without enabling unrestricted `file://` navigation. |
+
+Browser settings choose new-tab defaults, where links open, global Aiden browser access, and whether automation reveals it. Each workspace can inherit, enable, or disable browser access separately. Incognito is never the persistent default. Websites cannot read the OS clipboard, request geolocation, or display notifications. Only sanitized clipboard writes from an owned, same-origin main frame can receive automatic permission; third-party frames and unknown permissions are denied.
+
+## Annotating a page
+
+Choose **Annotate** or press **⌘.** while the browser is focused. Select an element on the live page, then add other elements, regions, drawings, a comment, or per-element style changes. Text, colors, borders, sizing, and spacing preview live; originals are restored when you cancel or add the annotation. Erase removes selected elements, regions, or drawings at a point. Available React development-source information is included when the page exposes it; annotation also works on non-React pages.
+
+**Add to chat** or **⌘Enter** appends the annotation to the existing draft. The context includes the URL, text, selectors, bounds, available source metadata, and the user's comment. A marked screenshot crop accompanies it when the current model supports images and attachment limits permit. Text context remains available for text-only models or capture failure. Page-derived content is labeled untrusted evidence. Nothing is sent until the user sends the draft. If the current composer is unavailable (for example during a questionnaire), the editor keeps the annotation for retry.
+
+## Aiden tools and lifecycle
+
+An eligible foreground desktop workspace agent initially receives only `browser`, a discovery tool. Calling it installs fourteen executable tools at the next model-turn boundary: `browser_status`, `browser_open`, `browser_navigate`, `browser_resize`, `browser_set_appearance`, `browser_snapshot`, `browser_click`, `browser_type`, `browser_press`, `browser_scroll`, `browser_evaluate`, `browser_wait_for`, `browser_recording_start`, and `browser_recording_stop`. The gateway returns their names and usage guidance; it does not duplicate their schemas in the transcript.
+
+The initial added static context is **85 estimated tokens** (337 serialized characters), versus the original 2,679. Once activated, the gateway, fourteen schemas and browser guidance add **3,032 estimated tokens**, including the new local-file arguments. These numbers use Aiden's `estimateStaticContextTokens` characters/4 heuristic, not a provider tokenizer or billing measurement. Unrelated responses pay only the gateway cost. Effective disabled access removes even the gateway on the next generation. Host exclusions are respected before discovery.
+
+Discovery state lasts for the current generation, including compaction and emergency continuation. A new generation starts with the gateway again. Pi receives the actual executable tool registry through its next-turn context update; the outbound transform and durable compaction estimator use the updated registry and prompt. Compaction summarizes conversation history and retains recent call/result pairs; it does not remove active tool schemas or close browser tabs. Outgoing context keeps the newest three image-bearing browser snapshots, independently of Computer Use's three-image pool. Older screenshots remain in the private journal, with text and error semantics preserved. Model-facing snapshot text is capped at 32,000 serialized characters, with intact selected locators, failure-prioritized diagnostics and explicit omission counts. Text-only models receive no screenshots.
+
+These tools operate on the user's workspace tabs. Browser access authorizes navigation and page inspection in the selected profile, including background tabs when `open=false` or automatic reveal is disabled. Ask mode gates interaction/evaluation; it does not add a prompt for every navigation or read. Background tabs remain listed in Environment → Browser, and their calls remain visible in chat activity. Calls bind to the generation and workspace, serialize against the selected tab, and revalidate permissions and cancellation. Ask-mode interaction/evaluation approvals bind to the exact tab, page revision and arguments; navigation or human takeover invalidates them. A failed action invalidates actions already waiting in the same generation's queue. Later recovery can inspect a fresh snapshot. Keyboard expectations require the native Chromium debugger-source flag exposed by the pinned Electron build, plus matching keys/modifiers. Physical keyboard input, including identical or repeated keys, interrupts immediately; missing keyboard source flags fail closed. Electron omits that flag from mouse-down/up events, so a matching physical mouse event can consume a pending same-button expectation; a subsequent unmatched event interrupts. Mouse expectations are bounded and removed when dispatch settles. Electron upgrades must preserve the keyboard event contract or keyboard automation will stop safely. The private Assistant, Bots, headless generations and read-only subagents do not receive these desktop-only tools.
+
+`browser_open` and `browser_navigate` accept a local HTML/PDF `path` (or a local file URL) through the managed preview service. Every preview serves only its entry document and a finite declared asset set, with a separate origin for each distinct grant. Agent opens require explicit `assetPaths`. Undeclared sibling files are blocked, including inside the workspace. Workspace entries and declared workspace assets use existing workspace authority. Direct user file opens discover static HTML, CSS and JavaScript-module dependencies inside the owning workspace, including relative and workspace-root-relative asset paths, without executing page code. Discovery is limited to 64 files, eight dependency levels, 1 MiB per parsed source and 4 MiB total parsed source. It never grants directory access or follows computed imports, dynamic fetches, external URLs, or unrelated documents. Literal module imports, including literal dynamic imports, remain statically discoverable. Parsed sources are pinned by identity, content, size and modification time. Reopen the document after editing or touching a parsed source, including a same-content save, so Aiden can rebuild the asset grant; existing previews deliberately fail closed with 409. Missing or out-of-scope references found during discovery remain blocked and appear in browser diagnostics. Discovery does not resolve import maps, `new URL(..., import.meta.url)` worker/asset references or scripts injected at runtime; those unrecognized patterns do not produce a discovery warning. Pages that need them should run through their own development server, or use explicit `assetPaths` for supported ordinary asset requests. Worker requests do not receive implicit preview authorization. Explicit `assetPaths` bypass discovery and retain the exact supplied set. An outside-workspace document requires explicit approval for that exact file and any declared `assetPaths`, including in Full access mode. The grant is a main-only object with pinned file identities; model-supplied flags cannot authorize access. All local files are served individually, with no directory listing or mount of all `/tmp`.
+
+Managed previews bind to loopback on an OS-assigned port and use capability protection. Initial navigation uses a bootstrap token; subsequent declared-file requests use a main-injected header restricted to the owned workspace, exact destination origin, and committed requesting-frame origin. Preview cookies are not used, legacy preview cookies are stripped, and cross-origin redirects receive no internal header. Requests without an owned frame, including worker requests, receive no implicit authorization. Tabs, pending navigation and reads own their lifetime. Closing or navigating away from the final tab revokes access and drains existing requests for at most five seconds; hidden and floating tabs remain consumers. Failed opens, cancellation, owner/workspace disposal, changed root identity and shutdown release resources. No external server process or staging copy is created, so crashes leave no server child or staging files to recover. Original documents and user-owned development servers are preserved. Capability URLs and known tokens are redacted from textual tool results and diagnostics; screenshots remain visual page evidence.
+
+## Verification
+
+`npm run test:browser` covers contracts, action policy, profiles, cookie decoding/import, preview-server confinement, annotation context/capture, live-style reversion, and UI state. The three browser Playwright files cover actual Electron page interaction, a deterministic model's tool loop and Ask-mode approvals, live annotation, profile isolation, responsive and floating layout, native-view visibility, local HTML/PDF documents, valid WebM recording, input cancellation, and closing picture-in-picture during capture. Shared activity labels are covered by the desktop, Android, and iOS model tests.
+
+Validation includes focused browser/context/runtime suites, actual Electron agent discovery and execution, exact temporary-file approval and asset loading, shared listener lifetime, stale approvals, hover interception, cursor cleanup, owner reload and workspace/file-identity revocation. Desktop, Android and iOS activity labels include discovery. Initial feature validation passed: `npm test`, `test:preflight`, 118 browser tests, 266 compaction/runtime tests, all 15 original Electron browser cases, TypeScript, E2E TypeScript, lint, build and focused Android tests. iOS app/test targets pass generic-device build-for-testing; XCTest execution requires a physical device under repository policy.
+
+PR review follow-up validation passes: 140 browser tests (including real Chromium cross-port credential isolation), 20 Electron browser cases with no flaky retries, TypeScript, E2E TypeScript, lint and production build. Direct user-link coverage verifies discovered CSS/module assets and a separate strict agent grant. Recording coverage decodes three immediate start/stop outputs as video; input coverage includes native keyboard source flags, same-input collisions, and mid-action workspace/global access revocation.
+
+Real installed-browser import acceptance depends on available profiles and OS permissions. Native-window captures are required for visual checks: a renderer-only Playwright screenshot does not include Electron's native browser view.
+
+
+## Edge cases and recovery
+
+| Case | Handling / remaining consideration |
+| --- | --- |
+| Browser is closed, selected tab disappears, or user selects another tab | Open explicitly; generation selection stays pinned, and stale IDs fail instead of retargeting another page. |
+| Discovery repeated, excluded, disabled, cancelled, or compacted | Idempotent turn-boundary registration; excluded tools stay excluded; disabled new generations have no gateway; compaction preserves active inventory and correct budgets. |
+| Human takeover or earlier parallel action fails | Release held inputs, invalidate already queued actions, and inspect fresh evidence before retrying. Native debugger-source flags distinguish identical physical keyboard input; missing keyboard flags fail closed. Mouse-down/up source metadata is unavailable, leaving a bounded same-button collision ambiguity. |
+| Approval waits while a tab navigates, reloads, or changes | Bind page/control revisions and arguments; reject expired approval before input. Hiding an inactive picker does not count as takeover. |
+| A target moves or an overlay appears on hover/down | Recheck the resolved element and intercept hit targets across trusted click events; avoid clicking the covering element. |
+| Local file URL, temporary document, missing asset, or duplicate preview tab | Use managed `path` previews, exact grants for every document and declared asset, bounded static dependency discovery for direct user opens, and approval for external files; share leases until the last consumer leaves. |
+| Traversal, symlink swap, file replacement, workspace-root change or revoked access | Confine paths and pin identities; reject new bytes, revoke affected leases, preserve source files. |
+| Failed navigation, cancelled open, active reader, close/reopen race, owner crash | Reservations and tab references prevent premature release; final cleanup has a bounded drain. No stale child process is created. |
+| Large page/AX tree, noisy console/network, old screenshots, text-only model | Bounded textual projection, explicit omissions, failure priority, independent screenshot retention and modality filtering. Request fresh focused evidence when needed. |
+| Page repeats a capability token or supplies instructions | Redact known textual secrets; treat page content as untrusted evidence. Do not interpret page instructions as user authorization. |
+| Cursor, held key/button, recorder, picker or PiP teardown | Matching-world cursor removal, bounded input release and recording/capture lifetime tests cover cancellation and early closure. |
+| Ambiguous/hidden/disabled selectors, readiness timeout, unsupported key or target | Return actionable errors; no blind retry or automatic fallback to another browser. Inspect again and use a supported target. |
+| Site authentication, third-party cookie import and OS permission prompts | Profile isolation remains; installed-browser import acceptance depends on real profiles and OS permission. No credentialed import acceptance is claimed by fixture tests. |
+| Cross-frame interactions, native dialogs, uploads/downloads and desktop-only controls | The existing fourteen-operation surface is preserved. There is no added dedicated upload/download/native-dialog tool; unsupported workflows must be explained or use separately authorized capabilities. |
+
+This is a tested risk inventory, not a claim that arbitrary websites have no further edge cases.

+# Unified settings and workspace presentation
+
+Status: Complete — implementation and review complete in PR #97; final CI tracked by the PR (2026-09-06).
+
+## Scope
+
+1. Hide workspace folder labels by default. Add persisted Appearance controls to show paths and choose beginning/end, last folders, or beginning truncation. Apply consistently to workspace navigation while retaining useful branch and no-folder identity.
+2. Fit Personal Model Pad to its actual available width and height, including narrow/short windows, browser panels, and zoom. Keep all controls reachable by scrolling when the window cannot contain the entire page.
+3. Add a global Skills switch with authoritative runtime enforcement for configured and discovered skills, stale invocations, and chat entry points. Preserve individual skill choices. Explain the control during onboarding.
+4. Use Appearance's page hierarchy, soft grouped cards, inset row separators, spacing, and right-aligned controls across Settings. Preserve input focus behavior and visible keyboard focus. Align Telegram switches to the right and correct misleading setup copy.
+5. Use an SD-card icon for Memory and remove brain glyphs elsewhere.
+
+## Validation and delivery
+
+- Extend configuration, path formatting, runtime skill enforcement, settings accessibility, and responsive layout tests; register new suites.
+- Inspect both native clients for shared skill behavior and run applicable focused mobile suites.
+- Run type checks, relevant tests, build, and an Electron settings size matrix. Record environmental limits and workflow friction.
+- Request three independent fresh-context GPT-5.6 Sol reviewers at medium effort: adversarial runtime/security, edge cases/responsiveness, and integration/accessibility/regression. Fix validated findings and rerun affected checks.
+- Create a PR in sambitcreate/aiden-agent. Have a fresh GPT-5.6 Luna reviewer at max effort watch CI; fix failures until all required checks pass.
+- Update project memory and archive this plan after delivery completes.
+
+## Implementation and verification
+
+- All five scope items are implemented. Settings uses shared page, group, row, and semantic token conventions documented in `docs/settings-design-system.md`.
+- Workspace paths are opt-in, persist across relaunch, support all three formats, and preserve grapheme clusters and meaningful whitespace. Duplicate workspace names retain distinct short IDs when paths are hidden.
+- Model Pad uses measured available space. Electron coverage includes 390–1440px widths, short windows, 125%/150% zoom, open model/insight panels, keyboard movement, and saving. A 160px minimum canvas remains scrollable in very short windows.
+- Global Skills enforcement covers discovery, tools, stale attachments, queued Telegram commands, existing chat journals/compaction, and Bot runtime grants without erasing saved choices. An Electron provider-boundary test verifies hidden skill instructions are absent from the next request after disabling Skills.
+- Three fresh-context GPT-5.6 Sol medium reviews covered runtime/adversarial behavior, layout/edge cases, and integration/accessibility. Confirmed findings were fixed and regression-tested; runtime re-review reported no remaining actionable findings.
+- Final local checks passed: full `npm test`, production build, lint, renderer and E2E type checks, focused runtime/settings/onboarding suites, existing model-picker E2E, new settings E2E, and responsive Model Pad E2E. Android's 12 focused Bot contract tests passed. The iOS test bundle compiled, but execution was blocked because both connected physical iPhones were locked; repository policy prohibits simulator fallback.
+- PR [#97](https://github.com/sambitcreate/aiden-agent/pull/97) is open. Initial CI passed main verification, native/iOS compilation, Android, and release contracts. Full Electron CI exposed duplicate group headings and an outdated workspace selector, now fixed with stronger heading coverage. Model Pad reachability now retries scrolling through layout settlement and checks the actual scrollport with diagnostic bounds. All affected local Electron checks passed; fresh CI is pending.
+
+## Additional PR review remediation
+
+- The corrected UI revision `6278ff4de` passed all CI checks, confirmed by the GPT-5.6 Luna max watcher.
+- Repository automated review then identified operator-compaction and additional Bot-catalog paths. Manual LLM/VCC compaction now uses visible-only history while Skills is disabled, and disabling cancels active operator compactions. Real journal/provider tests verify no hidden skill payload or cancelled checkpoint.
+- Bot catalogs pause discovery and incarnation reconciliation. Saved exact skill bindings survive disabled reads, unrelated edits, restart, and re-enable; real content changes still fail closed. Targeted editor catalogs and authenticated dormant chat-selection entries preserve saved choices without granting new skills.
+- The additive optional catalog `skillsEnabled` field is documented in the normative API/OpenAPI and shared fixtures. Desktop, iOS, and Android preserve saved choices while still preventing unavailable additions and rejecting malformed flags. Android 14 focused tests passed, iOS generic app/test compilation passed, and an independent source review found no actionable concerns. Physical iPhone13 execution remains blocked by the lock screen.
+- Focused remediation suites, full local tests/build/E2E, lint, type checks, and implementation CI passed after all fixes; see Delivery below.
+
+## Delivery
+
+PR [#97](https://github.com/sambitcreate/aiden-agent/pull/97) contains the completed implementation. Full local tests, production build, lint, type checks, and Electron E2E passed after all fixes. The CI workflow and Release consumer contract passed for implementation revision `4ad6e5ec1`, confirmed by the requested GPT-5.6 Luna max watcher. The final archive-only revision is tracked by the PR’s live checks. iOS physical execution remains the explicitly recorded device-lock limitation.
+
+## Mobile transport follow-up
+
+Automated review found that the HTTP catalog route rejected Android’s Bot query and iOS never supplied it. Reopened delivery and wired the optional validated query through the authenticated router and both native clients, isolate per-Bot cached catalogs on iOS, and added real HTTP/URL request regression tests. Generic new-Bot catalogs must remain free of dormant saved skill choices.
+
+The follow-up now forwards validated targets through the router and all existing-Bot iOS flows, keeps new-Bot catalogs generic, and isolates iOS offline catalogs by Bot. Android 33 focused model/client tests, iOS 13 source-contract tests, app/XCTest compilation, lint, types, release-consumer checks, and production build passed. Independent iOS source/test review found no issues. Full Remote API tests passed (357 plus 7 LAN transport tests); final CI is recorded in the PR checks.
+
+## Artwork scope update
+
+At the user’s request, reverted the replacement Thinking Controls onboarding illustration to the existing base asset. This PR adds or changes no onboarding image assets. Existing onboarding references and the feature asset contract remain intact.

+# Settings design system
+
+Settings adapts the Appearance page and the desktop UI references in `chatgpt-desktop-ui-inspiration.md` and `chatgpt-ui-element-specimen.html`.
+
+## Composition
+
+- `SettingsPage` owns the page heading and description. Destinations with their own header/actions use `settings-page-heading` and suppress the wrapper heading. Keep one destination heading; group titles describe a distinct group rather than repeating the page title.
+- `FieldSet` supplies `settings-group`, `settings-group-title`, and `settings-group-card`. Existing custom connection lists use `settings-card` for the same surface.
+- `Field` supplies a label/description group, inset separator, and `settings-field-control`. Default rows put controls at the right; vertical rows suit editors, lists, previews, and complex forms. Direct switches retain a trailing column even on narrow windows.
+- Use the shared Button, Switch, Input, Select, and other control primitives. Inputs keep their resting border and use background/caret focus states. Non-text controls retain a neutral `--focus-ring` outline.
+
+## Tokens and adaptation
+
+The `.settings-responsive` container defines `--settings-card-radius`, `--settings-card-fill`, `--settings-row-inset`, and `--settings-row-gap`. They derive from Aiden's semantic theme tokens; Appearance cards use these same variables. Shared heading metrics are 26/32px, with secondary copy and 26px spacing before content. Groups use soft neutral surfaces, neutral borders, inset separators, and restrained elevation. Status appears in semantic labels, icons, and fills, never decorative colored borders.
+
+Rows respond to their allocated content width, not the whole window. Below 540px complex controls stack under descriptions, while switches remain on the right. Grid groups must use `minmax(0, 1fr)` / `grid-cols-1` so long provider names or endpoints cannot force horizontal overflow. Controls and text must stay reachable without horizontal page scrolling.
+
+Model Pad measures the actual scrollport, wrapped toolbar, labels, and legend. Its square is constrained by both remaining height and column width. On very short or highly zoomed windows, it retains a usable 160px square and the Settings page scrolls; the Pad and its labels remain reachable. Ordinary window allocations show the full canvas and legend together. Opening model or benchmark panels uses the same measurement.
+
+## Workspace labels
+
+Appearance owns `showWorkspacePaths` (default false) and `workspacePathFormat` (`middle`, `end`, or `start`). Older v1 preferences normalize to hidden paths. The sidebar and picker follow persisted/live-preview changes, and measure their own text allocation so CSS does not replace the selected truncation with end clipping. Preserve legal whitespace, emoji, and combining characters. These strings are display-only; filesystem operations always use the full original path.
+
+Duplicate workspace names receive a short stable ID suffix in both visible and accessible names. Worktree branches and folderless workspace identity remain available when paths are hidden. Destructive confirmation and permission-scope review still identify their exact filesystem target.
+
+## Icons and illustrations
+
+Use `MemoryCardIcon`, an SD-card silhouette, for Memory. Do not introduce brain glyphs or brain illustrations. The existing onboarding artwork is outside this Settings change.
+
+## Checks
+
+`npm run test:settings-design` covers preference defaults/migration, path formats and identities, and structural/accessibility contracts. The deterministic Electron suite includes `settings-unification.spec.ts` (path persistence and all settings at 390/600/1280px) and `model-pad-responsive.spec.ts` (window/zoom/panel states, scrolling, keyboard movement, and save). Keep layout assertions tied to rendered geometry rather than only source strings.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
