v0.4.0 · Product IA Release

v0.4.0 - 2026-06-12

This release completes the v0.4 product information architecture refactor and publishes the same committed tree to GitHub and ModelScope.

Scope

Move daily product workflows into feature-owned foreground routes, narrow Admin to governance, and establish release evidence for the new product information architecture.

Included

• Foreground /fine-tune, /compare, /models, /benchmarks, /retrieval, and /experiments routes.
• Agent chat stream/resume/tool-decision transport in features/agent/chat-actions.ts.
• Agent submit/replay/resume/tool-decision lifecycle in features/agent/turn-lifecycle.ts and secondary analysis composition in secondary-analysis-panel.tsx.
• Agent runtime phase/stage/guardrail projection in features/agent/runtime-view-model.ts.
• Retrieval document CRUD, path import/probe, chunk inspection, and grounded query validation through canonical /api/retrieval* routes.
• Experiments artifact lineage, cross-feature navigation, filters, and explicit retention policy through /api/experiments.
• Admin Retrieval product state/actions removed and replaced by a governance handoff.
• Admin runtime transport and provider/telemetry read models moved into features/admin.
• Canonical /api/finetune transport plus dated deprecation headers on legacy Fine-tune, Retrieval, Models, and Timeline Admin APIs.
• Bilingual README route/version map, route ownership matrix, migration notes, and expanded route/screenshot smoke coverage.

Verification

• npm run typecheck:changed passed for core-agent, core-finetune, agent-api, agent-ui, admin, and app.
• npm run smoke:routes passed for Agent, Compare, Fine-tune, Models, Benchmarks, Retrieval, Experiments, and Admin.
• Route smoke also passed the Retrieval foreground snapshot, Experiments timeline, Fine-tune summary, Models discovery, Benchmark progress, Dashboard summary, sessions, and local runtime contracts.
• npm run smoke:screenshots captured all eight foreground/governance routes successfully.
• npm run build completed the optimized production build and generated all 42 static pages.
• In-app browser verification found no runtime error overlay, console error/warning, or horizontal overflow on /agent, /admin, and /fine-tune at 1280 px; the earlier foreground verification also covered /retrieval and /experiments.

Notes

• Legacy Admin APIs remain as thin compatibility wrappers until the September 30, 2026 sunset.
• Timeline retention is user-triggered and preserves failure/conflict and artifact-bearing events by default.
• GitHub and ModelScope packages are generated from the same committed Git tree.
