# Proof index for [#24113](https://git.cafe/pingdotgg/t3code/issues/24113)

Result: **partial matrix, not an unconditional pass**. The narrow desktop repro is visibly fixed. The existing 390px provider-breadcrumb/metric overlap remains on both revisions. S26 Electron evidence and parts of R04 are missing; pointer rail drag/nonzero animation and frame-level refresh-busy assertions are not proved. See the coverage report for the exact list.

Captured product head [2e7b0091fd](https://git.cafe/pingdotgg/t3code/commit/2e7b0091fd3b44a4a01912c055c3294fc09fc53e), exact base [eb1510d249](https://git.cafe/pingdotgg/t3code/commit/eb1510d249). Final fixture-only branch head **[b26c26e20e](https://git.cafe/pingdotgg/t3code/commit/b26c26e20e4f85574be5fca8b62c1059ed8351e9)**. No product file changed after capture. Branch clean; no PR, push or watch.

82 real-app stills; 10 matched narrated recordings; 41 zero-threshold ×8 amplified diffs and 41 threshold-16 maps, plus raw unamplified diffs. DPR 2 / font scale 1 (16px) / UTC. T3 preview downsamples desktop PNG exports to maximum width 1280; CSS viewports are separately measured.

Only synthetic Claude usage was visible after explicit provider-path isolation. Some fallback readers still used host HOME during the existing capture; lead review-2 reported Grok/Pi had zero usage files and Antigravity was absent. The final fixture script prints HOME/XDG_CONFIG_HOME/AGENT_CLI_CREDENTIAL_STORE isolation instructions for reproduction. Existing evidence was not recaptured after this fixture-only correction.

## Still pairs

Zero diff = absolute RGB difference, zero threshold, amplification ×8, clipped at 255. Threshold map = red where maximum RGB channel delta >16, otherwise white. No further alignment, masking or resampling. Both operate on matched exported PNG dimensions. The written differences report includes every nonzero scanline band and measured visible-text/header differences.

## Final workspace and process state

Lead session 16025 remains available: web 7771/PID 2093610, backend 15811/PID 2093623. Owned Electron attempts and helper sessions stopped; no debug port 19313/19314/19315 remains listening. Only the seed script was committed; no evidence assets were committed. Scoped formatting/lint, syntax, sandbox seed execution and live-home guard passed. No repository-wide checks.

Additional fixture changes since reviewer snapshot [f6c9cde345](https://git.cafe/pingdotgg/t3code/commit/f6c9cde3459bf478b0ddcc56e80978bbeb8e3a7f): NodeFSP/NodePath namespace imports/usages, explicit scratch home/config/OpenCode directories, host-reader HOME/XDG_CONFIG_HOME/credential-store startup hint/comment. The final HOME correction was a separate commit.

FRICTION CAPTURE | Desktop PNG export downsampling | Preserve viewport/PNG dimensions separately.
FRICTION DATA | Disabled readers can fall back to host HOME | Explicit sandbox paths and host launch settings; report original empty host fallbacks.
FRICTION DESKTOP | Native manager tried to own existing sandbox | Keep lead server available; S26 remains missing.
FRICTION POINTER | Existing mobile overlap and base narrow-header overlap | Preserve evidence and label programmatic menu activation.
