Solution written to ~/solution.md. I verified the fix block locally: bash -n clean, parser unit-tested against all router shapes, and the positive/negative (empty → FATAL, exit 1) paths exercised with stub routers. Note: this sandbox's dagger binary is pre-hardening (33d789a), so the post-422f292 fail-closed branch can't be executed here; I confirmed via disassembly that the old toolExecutorModel had no such branch and that splitModel splits on the first /.

The scheduler PM lane (coding-hermes-scheduler-pm, pm-standin-tick.sh → dagger run examples/coding-hermes/pm.ts) died 507 ms after start, at the first node:
node "f48c23fde265/read_state": qjs: eval failed: Error: tool error: DAGGER_TOOL_MODEL:
explicit provider/model route required: set both provider and model, or use model "provider/model"
read_state failed → dependency failure skipped 19/20 nodes → zero proposals, board pushes, or ledger writes. The fail-closed bridge did its job; the launcher took the hit.
<project> binary rebuilt 2026-09-15 08:42Z (carrying 422f292 + 1f6e8c0) changed src/bridge/hermes_api.go:toolExecutorModel from "read DAGGER_TOOL_MODEL, else return empty (caller falls back to the gateway PAYG lane)" to fail-closed: raw tool() nodes require an explicit provider/model route, with no gateway fallback.pm-standin-tick.sh was the only launcher among {worker-tick.sh, scheduler-foreman-tick.sh, dagger-role-tick.sh, qa-scheduler-tick.sh, pm-standin-tick.sh} that never exported DAGGER_TOOL_MODEL. It "worked for years" because the old binary silently defaulted raw tool() calls to the gateway PAYG lane — it was also silently billing the wrong lane. The hardening turned the latent gap into a hard failure at the first tool() node.toolExecutorModel splits DAGGER_TOOL_MODEL on the first / into (provider, model). A value with no / yields an empty provider, which the new code rejects. Correct value: provider/model (e.g. zai-glm/glm-5.3-flash).Diagnosis chain: run log → bridge source (toolExecutorModel) → git log -S DAGGER_TOOL_MODEL → binary mtime (08:42Z) vs. previous two checkpoint DBs (both completed|20, green before the rebuild) → sibling-launcher grep (only PM missing) → router_spawn.py resolve test (P8_SYNC head zai-glm/glm-5.3-flash for the -pm row).
Mirror scheduler-foreman-tick.sh's canonical block into pm-standin-tick.sh, before any dagger serve / dagger run. An empty resolution is a router-attributed FATAL on stderr and exit 1, so the launcher fails before any bridge contact.
