From 6ec5a6136b05f308145104f404c6ff13cca22a2c Mon Sep 17 00:00:00 2001 From: Yif <877193178@qq.com> Date: Mon, 3 Aug 2026 19:58:58 +0800 Subject: [PATCH] feat(web): show turn run time with hover-revealed time chrome Derive turn wall time from adjacent logged timestamps (no new session events): the actions-owning assistant footer gains a localized "Ran for {duration}" label, and the running TurnStatus label gains a live elapsed clock anchored to the same logged trigger so a mid-turn reload keeps the real elapsed time. Message time chrome is now hover-revealed on hover-capable devices, keeping icons visible and layout stable. --- .../2026-08-03-web-turn-run-time.i18n.yaml | 6 ++ .../feature/2026-08-03-web-turn-run-time.md | 27 +++++++ .../2026-08-03-web-turn-run-time.zh.md | 27 +++++++ .../src/client/chat/AssistantMarkdown.tsx | 8 +- .../src/client/chat/ChatView.module.css | 9 +++ .../src/client/chat/ChatView.tsx | 34 ++++++++- .../client/chat/MessageIconActions.module.css | 23 +++++- .../src/client/chat/MessageIconActions.tsx | 12 ++- .../src/client/chat/MessageItem.tsx | 2 +- .../src/client/chat/chat-flow.ts | 37 ++++++++++ .../src/client/chat/message-chrome.ts | 13 ++++ .../ui-conversation/src/client/locales.ts | 2 + .../ui-conversation/tests/chat-view.spec.tsx | 73 ++++++++++++++++++- 13 files changed, 263 insertions(+), 10 deletions(-) create mode 100644 .agents/notes/implemented/feature/2026-08-03-web-turn-run-time.i18n.yaml create mode 100644 .agents/notes/implemented/feature/2026-08-03-web-turn-run-time.md create mode 100644 .agents/notes/implemented/feature/2026-08-03-web-turn-run-time.zh.md diff --git a/.agents/notes/implemented/feature/2026-08-03-web-turn-run-time.i18n.yaml b/.agents/notes/implemented/feature/2026-08-03-web-turn-run-time.i18n.yaml new file mode 100644 index 0000000000..c404d7797c --- /dev/null +++ b/.agents/notes/implemented/feature/2026-08-03-web-turn-run-time.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

Long turns give no live progress signal beyond the static activity label, and after the turn settles the wall time is not recoverable from the UI. Meanwhile the always-visible clock row adds visual noise to every message. + +## Decision + +Turn wall time derives from adjacent logged timestamps, with no new session events: `turnStartTimes` maps each turn to the nearest preceding user/steering node's time, and the actions-owning assistant footer renders `time - turnStart` as a `Ran for {duration}` label next to the clock. The running `TurnStatus` label gains a live elapsed clock anchored to `lastInputTime` — the same logged instant the footer measures from — so a mid-turn reload keeps the real elapsed time and the final label matches the live clock. The clock appears only after 15 seconds so short turns keep the plain label. + +Time chrome (clock and run time) is hover-revealed: message containers opt in with a `data-time-hover-root` attribute, and `MessageIconActions.module.css` fades the time label in on container `:hover`/`:focus-within`. The rule is scoped to `@media (hover: hover)`, so touch devices keep the always-visible label; opacity (not display) keeps the layout stable. Copy/branch icons stay always visible. + +## Alternatives considered + +**A dedicated turn-start session event.** Precise, but adds a model-invisible event type solely for UI display; the adjacent-timestamp fold matches the trajectory table's existing derivation family and needs no log change. A turn whose trigger is outside the loaded window simply omits the label. + +**Anchoring the live clock to component mount.** Simpler, but a mid-turn reload would restart the clock at zero and disagree with the eventual footer label. Mount time remains only the fallback when no input node is in-window. + +**Hiding the whole actions row until hover.** Rejected in review: copy/branch are affordances worth discovering, and row-level show/hide risks layout shift. Only the passive time text is hover-gated. + +## Consequences + +Turn duration is visible live and after settlement without new session state, and the two readings agree by construction. The run-time label is absent for turns whose triggering input fell outside the loaded window.
