Branch-length batch covering tooling, the model layer, the Web App and the public
surfaces. Highlights:
- Changelog: a per-release `changelog/<version>/` tree, grouped by the surface each
change touches, with a root CHANGELOG.md holding one line per release.
- Dev startup: `scripts/dev-prebuild.mjs` serializes the skills+core prebuild behind a
lock and keeps `pnpm install` current; `pnpm dev` runs server+web together.
- AgentHub 0.3.3 -> 0.4.0: OmniMessage complete payloads carry one opaque `fidelity`
object in place of item-level `signature`/`phase`, threaded verbatim through Trace,
replay and resume; malformed classification adapted to the new error types.
- Model layer: a model is always referenced by an explicit `(provider, model_id)` pair.
The provider is never inferred, guessed or defaulted -- both the catalog inference and
the unique-match config resolution are gone, and CLI, SDK, server routes and
run_subagent all require the complete pair. Catalog gains the Qwen Token Plan, Qwen
Pay-As-You-Go and Fireworks AI gateways, plus an expanded OpenRouter group.
- Web App: catalog preset sync and per-group speed test on the Models page, positional
slash commands, a markdown renderer, skill-library update reminders, and a vertically
centred draft page whose upward menus size themselves to the room available.
- Public surfaces: restructured READMEs, the penguin.ooo landing site and blog, refreshed
benchmark results for both suites, and the demo videos playing on the landing page.
Includes the fixes from a full review of the branch: 23 confirmed findings, among them a
provider-inference bug that could send one vendor's API key to another vendor's endpoint,
and an Escape handler that destroyed the composer's contents unrecoverably.
Verified on the branch head: pnpm test (1127 passing, 7 packages), pnpm typecheck and
pnpm format:check clean, Playwright e2e 14/14.
