# Evidence: #15725 · T3 Connect sign-in surfaces offer Retry after Clerk fails to load

Before = `8d3b061121` (main merge-base), After = `492c26c4e6` (fix/issue-15725). Both are the real built app: the desktop rows use the built Electron app with the web bundle swapped (`client-before` / `client-after`, after rebuilt at 492c26c4e6). The hosted rows serve the same two bundles as `https://app.t3.codes` through a local HTTPS stand-in. No component harnesses.

**Rows captured: 20 / 24 matrix rows** (all 16 "affected" rows except S7/W7/H4/C4, plus every control row). X1 was captured in the real hosted app with a path-level failure, not a harness.

## What else changed (every visible difference at fuzz 0)
Nothing below falls outside the fix title, except the two pixel-level items at the end, which are not caused by the fix.
- Settings footer (S2, S6, X1-S): an empty footer becomes "↻ Retry T3 Connect". Only the 157×14 footer region differs.
- Wizard (W2, W6): the label changes from "Loading sign-in…" to "Couldn't load. Retry". The T3 Connect icon and label also go from the dimmed disabled style to full enabled contrast, because the trigger is now enabled. This is intended, but it is a visible change beyond the label.
- Wizard W5 (pairing in flight): only the label changes. The trigger stays disabled in both builds.
- HostedEmptyState step 1 (H2, X1-H): the disabled "Sign in" becomes an enabled primary "Retry sign-in". This is a different width, so the diff region is 133×32.
- /connect (C2, X1-C): a new "Retry sign-in" button grows the card, and because the card is vertically centred, **the whole card shifts up about 28 px**. That is why the diff covers the full card (648×378). It is a layout consequence of the added button.
- Behaviour, from the recordings: Retry reloads the page. In W4, that reload resets the wizard's unchecked fs-11 checkbox back to checked. The fix comment says this is expected ("a reload is the only recovery"), but users lose wizard input.
- Not from the fix: S2 W·D has a 1×100 px column at x=1439, y=81–180. That is the overlay scrollbar thumb caught in a different fade state.
- Not from the fix: W5 has 1–3 px corner pixels of the T3 Connect row border (about 10 px in total). These are anti-aliasing or rendering noise on a row whose state is otherwise unchanged.
- Identical at fuzz 0 (AE0 = 0): S1, S5, W1, H1, C1, H5 controls.

## Proof audit pass 2 (redone rows)
- **S3 (both builds):** the screencast stops sending frames when the page reloads, so the first S3-after video ended on an empty footer. The recorder now also takes a screenshot every 500 ms from the moment Retry is clicked, merged into the video by wall-clock time, and keeps going until 5 s after the final step. The last-frame stills are attached and checked against the page: after shows "Sign in to T3 Connect" (present: true), before shows the empty, stuck footer (present: false).
- **C2 W·L:** /connect ignores a light/dark change made after the page loads, so the first light pair was byte-identical to the dark pair. The light theme is now set before navigation (web.mjs row `C2L`). Mean gray brightness is 0.944 before and 0.943 after, against 0.054 and 0.056 for dark.

## Unverified
- S7, W7, H4, C4: these need a signed-in T3 Connect account, which we don't have.

## Conditions and notes
- Viewports: 1440×900 and 390×844, per the evidence brief. The matrix's "W = 1280×800" was not used.
- DPR 1, no font scaling, `prefers-reduced-motion: reduce` emulated. The clock is not frozen; every capture waits a fixed time from page load, the same in both builds.
- "Failed" stills are taken 25 s after load. Clerk reaches status `error` about 14 s after load with clerk.t3.codes refused.
- Desktop seeding: a fresh copy of the template `T3CODE_HOME`/`XDG_CONFIG_HOME` per run, plus `T3CODE_PORT=3791`, so the "Version" row URL is identical. The block flag is `/tmp/r15725/block`, on the lead's proxy :18925.
- Hosted seeding: `webstack.mjs` (static :18443, clerk stand-in :18444, CONNECT proxy :18926) with its own block flag `/tmp/r15725/block-web`.
- The hosted shell shows only a splash until Clerk settles, so H1 is the first frame where the steps render (3.9 s after, 6.5 s before).
- W3k focuses the trigger with `element.focus()`, then presses Enter through CDP Input.
- Rebuild any state: `swap.sh <before|after>`; `node desk.mjs <variant> S12 S5 W12 H5 S3 S4 W3 W3k W4 W5`; `node web.mjs <variant> H12 S6 W6 C1 C2 C2L H3 C3 X1 X1C X1S`; `diff.sh <name>`; `sbs.sh <row>`.
