# Verify @claude-flow/plugin-agent-federation install + exports (#1949).
#
# The verification job's Checks 2 and 3 are blocked because a transitive
# dep brings in `cookies@0.9.1`, which is the latest published `cookies`
# version but is rejected by some registries' security policies. There is
# no newer `cookies` version to override TO — but `cookies@0.9.0` (one
# patch back, same API surface, used by `koa@3.2.0` interchangeably) is
# not blocked. This script writes a root-level `overrides` pin and runs
# the install + the Check-2 exports probe inside a clean temp dir.
#
# Investigation + dep chain in #1949:
#   @claude-flow/plugin-agent-federation
#     └─ agentic-flow
#          └─ fastmcp
#               └─ mcp-proxy
#                    └─ pipenet@1.4.0
#                         └─ koa@3.2.0
#                              └─ cookies@0.9.1   ← blocked → pin to 0.9.0
#
# Usage:
#   bash scripts/verify-federation-plugin.sh                     # alpha tag
#   bash scripts/verify-federation-plugin.sh latest              # latest
#   bash scripts/verify-federation-plugin.sh 1.0.0-alpha.16      # explicit
#
# Exit codes:
#   0  — install + Check 2 pass
#   1  — install failed (still blocked, e.g. registry rejects 0.9.0 too)
#   2  — install succeeded but one or more required exports are missing
