I3829 — A provider declares whether its client drives a browser beside the server, and preflight says when this machine's bridge is missing

○PŘIPRAVENO vlna 0 · p2 · profil implementation · bezpečné souběžně

Part of a-provider-carries-the-contract-natively — Each agent client carries the contract through its own extension points, generated once and checked for drift.

Cíl

Give the provider declaration a third capability axis, `browser` (`bridge` when the provider's client drives a browser through a vendor extension whose tools arrive in the same session as this repository's MCP server, `none` otherwise), with the cited evidence every axis carries; project it through every surface that reports provider capability; and let preflight report, for a provider that declares a bridge and whose client configuration is present, whether this machine has the bridge's native messaging host, with the person-level remedy when it does not.

Proč

docs/MCP.md#claude-in-the-browser describes the one path that drives a page and the live mesh in one session (Claude Code with the Claude in Chrome bridge), but nothing declares it and nothing notices when it is missing: on 2026-10-21 a session found the bridge unconnected only by calling a browser tool, after the owner asked for the Claude, extension and browser integration to work by itself, be described and be enforced. A project cannot turn the bridge on (Claude Code ignores CLAUDE_CODE_ENABLE_CFC in a project's settings, code.claude.com/docs/en/chrome), so the repository's part is to declare the capability with its citation and to say, at the session's start, what the person has to do once. Id from id-block-0c, handed over by 0c on the board. A consequence found by a3 composing train 2 (2026-10-21): share/providers.yaml is read with unknown keys refused (ProviderOffersEntry, deny_unknown_fields), so an executable built before this issue refuses a tree that declares `browser` with \"unknown field `browser`\"; every seat whose cached MAJORDOMUS_BIN predates it must refresh it once this lands. That refusal is the vocabulary rule working, not a fault to relax.

Aktuální stav

share/providers.yaml declares episode and prompts per provider; nothing says which client drives a browser, and no check looks for the Claude in Chrome native host.

Cílový stav

Every provider carries browser + browser_evidence; providers.md, product providers, the MCP tool and the site's provider cards show it; preflight reports a missing bridge host as a finding with the /chrome remedy, never as a failure, and says nothing for a provider that declares none.

Závislosti

Žádné. Tento úkol je kořenem grafu.

Kritéria přijetí

• A provider entry without browser_evidence, or with a browser word outside the vocabulary, fails the read of share/providers.yaml with the path named
• claude-code declares browser: bridge with a citation; every other provider declares its value with one
• Preflight in a checkout whose .mcp.json is present reports the missing Claude Code native messaging host as a finding naming /chrome, and reports nothing when the host is present
• docs/generated/providers.md and majordomus product providers show the browser column from the one declaration
