# W6 — narrow long-label failure and recovered history
Before [701e13c](https://git.cafe/pingdotgg/t3code/commit/701e13cebb040d8433cd9aefb803ddd0d58c41d6); after [37441e9](https://git.cafe/pingdotgg/t3code/commit/37441e905194b062345c76d81caacd00d77ef5e5).
Environment: Linux x86_64 (fs-33); Chromium 148.0.7778.96 / Playwright headless shell build1223; no device emulation; DPR1; zoom/font scale100%; dark; prefers-reduced-motion: reduce; full viewport1440×900 except W6 390×844. Actual Electron44.10.0 under headless-desktop/Xvfb, --no-sandbox --disable-gpu, ImageMagick import, measured renderer1440×900/DPR1. Paired sides share synthetic data, scroll position and rendered clock within each run. Retained web clock20:00 UTC, desktop22:19 UTC; round2 rendered clock00:00 UTC, native Date.now/timers for grace/backoff. This row is390×844.
Same selective fault and real-time grace/retry/recovery as W5 at390×844, with an intentionally long synthetic hostname. Selected head recovery is settled, connected attempt4/generation1, history rendered, no Syncing messages or stale banner. A brief Syncing messages transition is visible in the actual recovery recording.

Before every selected still: fonts and network idle, reduced motion where supported, then two byte-identical screenshots500ms apart. All selected stills/diffs were opened and recordings skimmed. Diff0 amplifies every nonzero max-RGB delta (including one-level changes) in magenta; DiffT16 uses delta>16/255; unchanged after pixels dimmed to20%. Comparisons are within each row/pair, not across round1/round2 fixture variants. Transient splash/sync frames in recordings are actual startup transitions; selected stills exclude them.
