overseer - Codex binding

Thin Codex binding for the overseer operation of the livespec-overseer plugin. The behavior lives in the plugin-owned prose artifact at prose/overseer.md; this binding only resolves the plugin root and reads that contract.

Resolving the plugin root ($PLUGIN_ROOT)

Codex does NOT textually substitute a plugin-root token into SKILL prose, so resolve it explicitly, once, in this order:

1. If LIVESPEC_OVERSEER_PLUGIN_ROOT is set and non-empty, use it (explicit override for nonstandard dev setups).
2. Else if ./.claude-plugin/prose exists under the cwd AND ./.claude-plugin validates as this overseer plugin checkout (matching plugin manifest name), use $(pwd)/.claude-plugin.
3. Else use the newest valid installed cache root under $HOME/.codex/plugins/cache/livespec-overseer/livespec-overseer/<version>.
4. Else resolve the installed plugin's source.path from codex plugin list --json -m livespec-overseer using a robust executable lookup (command -v codex, $HOME/.local/bin/codex, then $HOME/.bun/bin/codex).

If resolution fails, STOP and surface those install instructions rather than improvising paths.

Invocation

Read $PLUGIN_ROOT/prose/overseer.md in full, then execute it end-to-end.

cat "$PLUGIN_ROOT/prose/overseer.md"

This binding adds NO operation behavior of its own; the operator contract lives in the prose.
