 | Live activity motion parity / `6c583620ff7ad3235b135af7107c0543467eecfa` | Corrects Pylon's rendering of already-classified `c7c1dfe4df` (#9709), `ce4712d5b0` (#9799) and the #444 port of `6cf0c6ea55` (#9093) / `c3b8825bf4` (#9606) | Pylon had diverged: `cdde7f3150` gave every active row the sweeping overlay and deleted `live-tool-shine`, while upstream reserves the overlay for label-only rows (`active && shimmer`, passed only by the Thinking row) and keeps the shine for tool labels. Restores upstream's `shimmer` prop, `animated = active && !failed` guard, row-level observer ref, overlay on worktree setup and compaction, and both CSS utilities byte-identical to upstream. That same commit also deleted `@utility visible-animate-spin` as dead while `spinner.tsx` and `refresh-icon.tsx` still applied it, so every spinner and refresh glyph was static; restored. Preserved: Pylon's `workingStepLabel`, and the `document.hasFocus()` gate AGENTS.md requires and upstream lacks. Cursor unchanged. | [Live activity parity #452](https://github.com/pylon-code/pylon/pull/452); 161 focused tests, web typecheck, scoped lint/format, region diffed against `t3code-upstream/main`. |
 | Skeleton loading pulse / `6c583620ff7ad3235b135af7107c0543467eecfa` | `21b9dda5afb00a33e228a68d2ccc885bba7285dc` (#9448) | Adopted. The shared `Skeleton` drops its swept gradient band for upstream's single stepped opacity pulse, whose keyframes were already byte-identical to the `ghost-pulse` Pylon ran on the pull-request ghosts; `ghost-pulse` is retired and every loading state now uses `animate-skeleton`. Preserve Pylon's `!seed` gate on the detail ghost, so a panel already showing real content does not breathe, and Pylon's own usage fill-in timing. The maintainer chose upstream theming and styling with only the logo staying Pylon's, which settles this kind of visual divergence in upstream's favour by default. Cursor unchanged. | [Skeleton pulse #451](https://github.com/pylon-code/pylon/pull/451); 339 focused tests, web typecheck, scoped lint/format. |
+| Panel links, markdown galleries, shared title model, usage columns, sidebar file drops, terminal link overrides, Codex limit naming and turn token telemetry / `6c583620ff7ad3235b135af7107c0543467eecfa` | Full ten-source list in PR #458, from #9132 through #10060 | Nine adopted; `b5d89038ae72142038dfa8cf69d49b7a607fe98e` is already covered as an empty duplicate of #7892. Turn telemetry stays inert without a Pylon PostHog key, is recorded only after runtime generation and session incarnation fences, and treats Prime, Cursor, Grok and Antigravity usage as unavailable; OpenCode uses the final #10116 step-retention design. Codex limit errors carry the session incarnation and Pylon keeps relaying every rate-limit notification. Preserve Pylon PR detection, environment-scoped PR caches, provider-instance settings writes, hub account keys, older-server window names, change-request row props and terminal external-browser fallback. New product analytics and usage data docs. Cursor unchanged. | [Web panels #458](https://github.com/pylon-code/pylon/pull/458); 1,687 focused tests, six package typechecks (web, server, shared, client-runtime, contracts, mobile), scoped lint/format; upstream UI evidence linked, no local client pass. |
