+# Agent Note: Hero fish hover swim morph
+
+Status: implemented

+
+## Problem
+
+Hovering the New Session hero fish (`EmptyHero.tsx` in `dsh-client-ui-conversation`) played a one-shot rigid CSS sway of the whole svg. The user wanted the whale to visibly swim — the tail wagging and the mouth curve lifting — which requires deforming the path geometry itself. CSS transforms cannot bend a subset of a path's curves, and the logo ships as one `FISH_LOGO_PATH` string in `dsh-client-ui-primitives`.
+
+## Decision
+
+Real curve deformation via SMIL `<animate attributeName="d">` cycling `rest → tail-up → rest → tail-down → rest` on the same 1.6s period as the CSS sway, which becomes continuous (`infinite`) for as long as the pointer stays. The two morph targets are generated programmatically (`/tmp`-run script, not checked in): parse `FISH_LOGO_PATH`'s absolute M/C/L/Z commands, rotate the tail region about a pivot with smoothstep falloff weights, bend the mouth/fin swoosh vertically with weight-squared falloff from its body anchor (a smile lift, not a rigid swing — rigid rotation read as detached), and emit structure-identical command strings SMIL can interpolate. The baked path constants live next to the component with the generation parameters documented. SMIL cannot ride CSS media queries, so a `hovering` state gated by `matchMedia('(prefers-reduced-motion: reduce)')` mounts the morph, while the CSS sway sits under `@media (hover: hover) and (prefers-reduced-motion: no-preference)`.
+
+The morphing fish reaches the hero as the fallback of the `conversation.hero.brand.mark` slot; no shipped package occupies it — `dsh-client-ui-brand-official` fills only the sidebar slots, since a feature plugin may not value-import `HeroFish` across packages ([client cross-package rule](../process/2026-08-23-client-cross-package-value-dependencies.md)) and the fallback already is the official mark. `FISH_LOGO_PATH` and `FISH_LOGO_VIEWBOX` are exported from `dsh-client-ui-primitives` for consumers that compose their own svg around the same geometry.
+
+## Alternatives considered
+
+**Vector-tool path editing for the morphs.** No interactive tool in the loop; programmatic weighted deformation was chosen because it guarantees the identical command structure SMIL `d` interpolation requires and makes amplitudes reviewable numbers.
+
+**Blowhole spout on hover.** Shipped first as three rising beads (richer whale-blow fountain, bubble-cluster, and ballistic-arc shapes were built and rejected in review), then removed entirely at the user's request: hover keeps only the shape morph and sway.
+
+**Occupying the hero slot with the official mark.** The previous arrangement; rejected because the static occupant shadowed the animated fallback, and animating the occupant instead would need the forbidden cross-package value import.
+
+## Consequences
+
+The hover swim is decorative (`aria-hidden`) and reduced-motion-safe (static logo on hover). The sway CSS targets the stationary `.fishHitbox` wrapper, so a slot occupant would sway too; the body morph lives only in the fallback `HeroFish`. Coverage is the component suite (`skeleton.client.spec.tsx`) asserting render states; the keyless snapshot harness records transcripts, not browser animation, so visual verification stays manual. Regenerating the morph targets requires re-running the (uncommitted) deformation script against `FISH_LOGO_PATH`; if the logo geometry ever changes, the baked constants must be regenerated with it.

+# Agent Note：主页鲸鱼 hover 游动变形
+
+Status: implemented
+
+[English](2026-08-12-hero-fish-hover-swim-morph.md) | 中文
+
+## 问题
+
+hover New Session 主页的鲸鱼（`dsh-client-ui-conversation` 的 `EmptyHero.tsx`）原本只播放一次整个 svg 的刚性 CSS 摇摆。用户希望鲸鱼有真实的游动感——尾巴摆动、嘴巴曲线上扬，这要求对路径几何本身做变形。CSS transform 无法弯曲路径中的部分曲线，且 logo 以单一 `FISH_LOGO_PATH` 字符串存放在 `dsh-client-ui-primitives`。
+
+## 决定
+
+通过 SMIL `<animate attributeName="d">` 做真实曲线变形，按与 CSS 摇摆相同的 1.6s 周期循环 `静止 → 尾上摆 → 静止 → 尾下压 → 静止`；CSS 摇摆改为持续循环（`infinite`），指针停留多久就游多久。两个变形目标由程序生成（在 `/tmp` 运行的脚本，未入库）：解析 `FISH_LOGO_PATH` 的绝对 M/C/L/Z 命令，尾部区域绕支点做带 smoothstep 衰减权重的旋转，嘴巴/鳍的内侧曲线以距身体锚点的权重平方做竖直弯曲（微笑式上扬，而非刚性摆动——刚性旋转看起来与身体脱节），并输出结构完全一致、SMIL 可插值的命令串。烘焙出的路径常量与组件放在一起，并在注释中记录生成参数。SMIL 无法响应 CSS 媒体查询，因此用经 `matchMedia('(prefers-reduced-motion: reduce)')` 判定的 `hovering` 状态控制变形挂载，CSS 摇摆则在 `@media (hover: hover) and (prefers-reduced-motion: no-preference)` 之下。
+
+变形鲸鱼以 `conversation.hero.brand.mark` slot 的 fallback 身份进入主页；没有任何发布包占据该 slot——`dsh-client-ui-brand-official` 只填充侧栏槽位，因为 feature 插件不得跨包 value-import `HeroFish`（[client 跨包规则](../process/2026-08-23-client-cross-package-value-dependencies.zh.md)），而 fallback 本身就是官方标志。`FISH_LOGO_PATH` 与 `FISH_LOGO_VIEWBOX` 从 `dsh-client-ui-primitives` 导出，供围绕同一几何自行组装 svg 的消费方使用。
+
+## 考虑过的替代方案
+
+**用矢量工具编辑路径做变形。** 流程中没有可交互的工具；选择程序化加权变形，因为它保证 SMIL `d` 插值所要求的完全一致的命令结构，且振幅是可评审的数字。
+
+**hover 气孔喷水。** 最初以三颗上升水珠的形式上线（更复杂的鲸鱼喷泉、泡泡簇、弹道水花造型都做出来后在评审中被否），随后按用户要求整体移除：hover 只保留形状变形与摇摆。
+
+**让官方标志占据主页 slot。** 即先前的安排；否决，因为静态 occupant 会遮住动画 fallback，而给 occupant 加动画又需要被禁止的跨包 value import。
+
+## 影响
+
+hover 游动是纯装饰（`aria-hidden`）且对 reduced-motion 安全（hover 保持静态 logo）。摇摆 CSS 作用于外层静止的 `.fishHitbox`，因此换成 slot occupant 也会摇摆；身体变形只存在于 fallback 的 `HeroFish` 中。覆盖由组件测试（`skeleton.client.spec.tsx`）断言渲染状态；keyless 快照体系记录的是对话转录而非浏览器动画，视觉验证仍需人工。重新生成变形目标需要对 `FISH_LOGO_PATH` 重跑（未入库的）变形脚本；若 logo 几何将来变化，烘焙常量必须随之重新生成。
