Connector registry

Every officially-maintained parsimony-<name> distribution declares itself to the kernel through entry-point metadata in its pyproject.toml:

[project.entry-points."parsimony.providers"]
<provider_id> = "parsimony_<name>:CONNECTORS"

Consumers (MCP hosts, agent frameworks, CLIs) discover installed providers at runtime via the kernel's parsimony.discover surface — see the kernel's docs/discover.md for the stable API. Entry-point metadata on the installed distribution is the authoritative source; this monorepo does not ship a separate index file.

Adding an officially-maintained connector

1. Add packages/<name>/ with a pyproject.toml that declares a [project.entry-points."parsimony.providers"] stanza (CI enforces this invariant; see .github/workflows/ci.yml → discover job).
2. Follow the conformance contract in the kernel's parsimony.testing module — CI runs assert_plugin_valid on every package.
3. Publish through the monorepo's per-package release workflow.
