# Arm A — the behavioural headline run, guard=scoped, on the OpenRouter backbone in .env.
#
# BACKBONE-AGNOSTIC. Everything model-specific lives in .env: OPENROUTER_MODEL picks the
# backbone, SCT_DATASET picks the results/<name>/ it writes to, OPENROUTER_PROVIDER pins the
# upstream so the price is the price you costed, and OPENROUTER_MAX_TOKENS /
# OPENROUTER_REASONING_EFFORT keep a reasoning backbone from spending its whole completion
# budget thinking and truncating its structured output. Switch backbone = edit .env and
# RESTART scripts/serve.sh, because the attacker origin binds SCT_DATASET at startup.
#
# THE DESIGN. Full control (a): the held target rotates across EVERY option of every scenario,
# not a 3-value subset, so ScenarioLeak averages over the whole label set and the k x k confusion
# matrix is complete. All five plant routes per scenario, `REPS` sessions per (target, plant)
# cell. Cold is denser for the scenarios whose cold arm is a genuine prior over options rather
# than a near-deterministic fallback, because those need a precise P_cold rather than a token one.
#
# ~1,600 sessions at reps=3. Budget roughly $22 and 40+ hours serial. Run it under tmux/screen.
#
# BALANCE GUARD. The run of 2026-08-13 died on HTTP 402 after 57 sessions and kept going, burning
# the rest of the plan into errored rows. This script refuses to start a scenario it cannot pay
# for, and aborts the moment a session comes back 402 — loudly, with a desktop notification and a
# non-zero exit. Note the check ISSUES a tiny probe request rather than reading a balance field:
# that same key reported $321 of `limit_remaining` while refusing every request, so only the
# provider's own admission control is authoritative (see orchestrator/spend.can_afford).
#
# RESUMABLE. Sessions already recorded without an error count toward a scenario's target, so a
# run killed at hour 30 picks up where it stopped. Errored rows never count — a dead session is
# re-run, never accepted, which is what keeps the resume logic honest.
#
# Usage:
#   bash scripts/run_behavioural.sh                    # run / resume everything
#   bash scripts/run_behavioural.sh sso_wall checkout  # named scenarios only
#   PLAN=1 bash scripts/run_behavioural.sh             # show the plan, run nothing
#   REPS=5 bash scripts/run_behavioural.sh             # denser cells
#
# Requires the servers to be up:  ./scripts/serve.sh

# checkout_neutral is trimmed here; leave SCENARIO_REPS empty for a backbone that does not.
