Why
projectBoard-plugin needs the coder subprocess to NOT inherit the host's identity/credential env (PROTOAGENT_*, A2A_AUTH_TOKEN, AGENT_NAME) — an arbitrary coding agent working on arbitrary repo code shouldn't hold the host's A2A bearer, and inherited scoping vars break target-repo test suites (projectBoard-plugin#78).
The first attempt (plugin PR #81) had no seam to hand a sanitized env to the ACP spawn, so it scrubbed os.environ in place at loop start — which gutted the live host: the server lost PROTOAGENT_HOME, and a graceful POST /api/restart re-execed as the default instance and died. Reverted in plugin PR #83; coder env is back to full inheritance.
Ask
Give the delegate/coding_agent spawn path an environment-shaping seam a caller can use per dispatch:
env_remove: [names or prefixes] (subtractive — the missing half), alongside the existing additive per-delegate env: map, or- an optional full
env= replacement on the spec the board loop passes when it dispatches a workdir-scoped coder.
Precedent: the host already strips CLAUDECODE* for nested Claude Code delegates — same shape, host-side, correctly scoped to the child. Dovetails with #2114 (console env editor for delegates): the same schema field serves both.
Refs: projectBoard-plugin#78, #81 (the regression), #83 (the revert), protoAgent#2114.
