Crate nexo_plugin_discovery 

Plugin catalogue discovery (Phase 98).

Fetches public plugin metadata from three sources, merges by crate_name, derives compat + trust tier, caches to disk with 24-hour TTL. Built as a standalone crate so a future microapp UI mirror (Phase 98 deferred #6) can reuse it without depending on the daemon.

Top-level surface:

• config::DiscoveryConfig — bake-in defaults + per-deployment overrides.
• cache::DiskCache — atomic temp+rename writer with TTL gate.
• types — typed payload re-exports of the wire shapes shipped by nexo_tool_meta::admin::plugin_discovery (98.5), with construction helpers + serialization-friendly defaults.

Modules

cache

Disk cache for the merged catalogue.

client

DiscoveryClient trait + DefaultDiscoveryClient orchestration.

compat

SDK / daemon version compat gate.

config

Runtime configuration for crate. Baked-in defaults match the “first-party Nexo” deployment shape — operators override per-knob via daemon main.rs.

manifest_fetcher

Fetch + parse a plugin’s nexo-plugin.toml from a raw GitHub URL (or other HTTP-accessible location). Derives the catalogue’s PluginCategory from the present manifest sections per the Phase 81.33.b.real auto-discovery design.

merge

Merge per-source contributions into a single catalogue.

sources

Discovery sources.

types

Local re-exports of the nexo_tool_meta::admin::plugin_discovery wire shapes plus internal construction helpers.
