Problem

On Android TV, the eight-digit sign-in code is hard to read from the couch. TvMarqueeCodeTiles gives each character its own rounded tile in a 260dp row, so the digits come out small. Both places that show the code use it: the QR sign-in screen and the phone pairing panel. Apple TV had the same design; see Silo-Server/silo-apple#864.

Solution

Draw the code as one line of bold text with no tiles, matching Apple TV:

• 40sp Inter Bold. The theme scales TV text by 0.86, so this renders at the same digit height as Apple TV's 72pt code on a 1080p screen.
• Inter's tabular digits (tnum) keep the columns even, and its slashed zero (zero) keeps 0 distinct from O in older servers' letter codes. The system monospace font, Droid Sans Mono, has no slashed zero, so 0 and O looked alike before. Apple uses SF Mono, which has one built in.
• The group space becomes an en space, because Inter's normal space is too narrow to separate the 4+4 groups.
• The code is measured as drawn and scaled down when it's wider than the card, which covers longer server codes, wide letter codes (W, M), and larger system font sizes.
• The code is laid out left to right in every locale, and its spoken description is unchanged.

Pairs with Silo-Server/silo-apple#865
Related issue: Silo-Server/silo-apple#864

Validation

• :androidTvApp:assembleDebug and :androidTvApp:testDebugUnitTest pass.
• Debug APKs of 8f5a5d6c and of the unfixed origin/main (2f9a6b9f) ran on a new Android TV emulator (API 36, 1920×1080, 320 dpi) against a Silo dev deployment.
• QR sign-in screen: before shows eight small digits in tiles. After shows large digits with no boxes, a clear gap between the groups, and a slashed zero (3790). The card still fits.
• Letter codes: local test builds with the code forced to WMWM WMWM and O0O0 0O0O, since the dev server only issues digits. The wide letters scale down to fit the card without clipping, and the slashed zero stays distinct from O. The forcing change isn't committed.
• Content description still reads Code: 4, 5, 7, 8, , 3, 7, 9, 0.
• Not checked live: the phone pairing panel. A phone simulator can't reach the emulator's pairing channel here. The panel uses the same composable and the same default card width, and the Apple TV pairing card was checked live.

Validation tasks: none

Evidence: https://evidence.siloserver.org/r/silo-android/pr-656/

Risks

Low. This is a visual change to one TV-only composable.

Follow-ups

• User manual: unaffected. It says the code is eight digits in two groups of four, which still holds.

AI disclosure

• AI harness: T3 Code with Claude Code
• AI tool(s): Claude Code, Gradle, Android emulator, adb
• AI model(s): claude-opus-5-5 (wrote the code); gpt-6.1-sol (plan review)
• AI involvement: The agent reproduced the problem on an emulator, wrote the change, and captured the evidence at a maintainer's request.
• Adversarial review: before implementation, gpt-6.1-sol reviewed the shared plan. It flagged that the TV theme's 0.86 text scale would leave the code smaller than Apple's. The size was set from the rendered digit height instead. A background review by gpt-6.1-sol of 0a9feea found that the per-character width estimate could clip wide letter codes such as WMWM WMWM. Fixed in 8f5a5d6 by measuring the drawn code.

📝 Walkthrough

The TV marquee replaces individual bordered character tiles with one centered text row. It formats codes in uppercase, adjusts text size to the available width, and retains per-character accessibility content.

Changes: TV marquee code rendering

Layer / File(s)	Summary
Responsive code row androidTvApp/src/androidMain/kotlin/org/siloserver/silo/tv/ui/components/marquee/TvMarquee.kt	TvMarqueeCodeTiles now renders one uppercase text row instead of separate character tiles. It converts spaces to en spaces, forces left-to-right layout, scales text to the available width up to 40sp, and uses Inter tabular digits with slashed zero. Per-character accessibility content remains.

Merge Risk: 🔵 Low · up to 0a9fe

Some older-server sign-in codes may be clipped, making them difficult to enter. Measuring the displayed code before sizing it would address this bounded risk.

The Evidence section contains only descriptive text and the literal EVIDENCE_LINK placeholder, not attached captures or a published evidence URL.

• QR sign-in code redesign — Android TV is missing before-and-after screenshots of the same screen and data; provide captures for the TV build/commit.
• Phone pairing panel code redesign — Android TV is missing before-and-after screenshots of the same panel and data; the body says it was not checked live because the phone simulator could not reach the pairing channel, so reviewers will need to decide whether that limitation is acceptable.

The evidence page is now linked in the PR body: before and after captures of the QR sign-in screen on the same Android TV emulator and server, with both builds named. The pairing panel wasn't captured live because a phone simulator can't reach this emulator's pairing channel. It uses the same composable at the same card width, and the paired Apple TV pairing card was captured live (Silo-Server/silo-apple#865).

The new measured-size behavior also changes how longer codes render in the phone pairing panel on Android TV, but the evidence link covers only the QR sign-in screen. The PR explains why the pairing panel could not be captured; reviewers will need to decide whether that limitation is acceptable for this updated rendering.
