dsh-whale-companion
English | 中文
A local-first DSH whale world. Privacy-safe session metadata becomes a draggable companion, 20 unlockable whale spirits, visible tides, a personal sea cove, gentle expeditions, and opt-in local whale-circle cards.
Version 2.6.0 targets DSH 0.1.2-rc.1. It retains the existing name, appearance, position, progress, collectibles, room presets and ImageGen species atlas. Background write failures cannot interrupt the DSH session; the affected progress update may be missed, and later updates remain accepted. Explicit user saves still report failure. Session flush and plugin shutdown wait for already accepted writes before the domain closes.
The selected minke now breaches through a fixed ink waterline, arches and dives back under it. The white-bellied silhouette uses 24 selected ImageGen drawings and 72 raster in-betweens: 96 frames at 40 fps in a 2.4-second loop. Both system and in-product reduced motion select the matching PNG still. The original Dive/Classic status animations are not replaced. See the design, full prompts and source record.

The GIF is a compatibility preview; format and browser timing limits apply. The plugin and native WebP use uniform 25 ms frame timing.

Unedited captures from a live local DSH Web session. Progress reflects that session; appearance follows the active DSH theme and viewport.
Features
- Complete 2.4.0 delivery: named companion, four adaptive voyage goals, ImageGen raster whale portraits, a raster-sprite common-minke animation, a compact quick card, XP feedback, six cove themes, local PNG/text sharing, and no runtime vector whale art.
- Session dates now prefer the real creation timestamp; late historical events cannot roll streaks backward; every text import is capped at 512 KiB before JSON parsing; durable writes are fully schema-validated.
- CI now mounts the actual built client bundle in a browser-compatible DSH slot/Remote harness and runs desktop, mobile, light-theme, and reduced-motion Playwright visual regression.
- A movable
shell.overlay whale supports pointer drag, keyboard movement, edge snapping, persisted viewport-safe placement, and one shared five-second local refresh. New tide moments appear in a bounded visible bubble; only milestones are announced to screen readers.
- Quiet, standard, and lively presentation modes stay in browser-local preferences. System reduced-motion always wins, and storage denial falls back safely without affecting progress.
- Whale Home now leads with a seven-day ocean journal, the current whale story beat, a visual cove preview, and a field-backed Privacy Ledger.
- The selected-species card, floating companion and quick card share the same breach animation and generated-art PNG fallback; the ocean layer remains static.
- 20 whale spirits unlock over Ocean Levels 1–100. Each maps its story and visible tide response to a safe event family, without changing model behavior.
- Live-only
session/created, user/message, and tool/result metadata drives bounded local tide moments. Repeated tool results still count toward legacy XP, but cannot farm tide moments, collectibles, or expedition progress.
- The Whale Home provides a tide timeline, local PNG postcard export, a 24-item collectible catalog, eight fixed room slots, three room presets, and a non-punitive expedition.
- Visitor bottles are isolated read-only room previews. They do not merge or overwrite the receiver's progress.
- Whale-circle cards are opt-in and local-file based. They exchange only a preset alias, species, skin, coarse activity buckets, and resonance stars. There is no account, networking, ranking, free text, prompt excerpt, task name, or tool data.
- Six themes adjust cove backgrounds, interface accents and ambient light; whale artwork retains its own colors. All 12 achievements, responsive layouts, keyboard controls, focus handling, and reduced-motion rendering are included.
Turns grant 10 XP, tool results grant 5 XP, and session starts grant 20 XP. Only user/message counts as a turn. Levels derive from XP, and streaks use UTC session-start dates. Missing days never remove progress or collectibles.
Privacy
The Host reads only session id, event sequence, event type, and timestamp. It never reads, stores, exports, or renders prompt text, assistant output, code, paths, tool arguments, or tool results.
New in-memory receipt digests use an HMAC key that never leaves the Host process. The durable receipt window is capped at 4,096 records, so it prevents recent duplicate live delivery, not permanent replay across Host restarts. Backups intentionally contain no receipt digests, session ids, or event data. PNG postcards and community cards are generated locally and contain only the documented safe fields.
Install
Install directly from GitHub into the DSH Web profile:
dsh plugin --profile web add github:LeemanCheung/dsh-whale-companion
Restart the existing DSH Web process and refresh its page.
Model Experience
This plugin adds no model prompt, tools, messages, token usage, or KV-cache content. It observes committed session event metadata on the Host and exposes browser UI only.
Known limitations
Progress lives in one DSH storage backend and does not synchronize across devices. The overlay polls every five seconds because the current host Remote event allowlist has no package-local whale-state push route. Whale-circle cards are intentionally local import/export only; a hosted community requires a separately owned, authenticated, and moderated transport provider.
Development
From the repository root run:
python -m pip install -r requirements-art.txt
corepack pnpm typecheck
corepack pnpm verify:minke:rebuild
corepack pnpm verify:minke
corepack pnpm verify:species:rebuild
corepack pnpm test
corepack pnpm build
corepack pnpm pack:check
The art pipeline is pinned to Python 3.12, NumPy 2.3.3, and Pillow 12.3.0. corepack pnpm art:minke rebuilds the transparent sprite; corepack pnpm art:species normalizes the checked-in ImageGen 20-species atlas. The production client embeds both raster assets and contains no runtime vector whale drawing.
Visual snapshot baselines are maintained on Ubuntu in CI. Other platforms still run the interaction, motion, reduced-motion, and narrow-layout assertions, but do not create release-candidate screenshot baselines.
