β.3 — AGENTS.md + vetted solve-script template

[jack-champagne]

Phase: β — Schuster demo · Plan task: β.3 · Est: 1 pd · Suggested role: Dev C

What to build

Author AGENTS.md (the LLM's script-authoring conventions) + one vetted template script the LLM fills in: build system via TransmonSystem(; ω, δ, levels) (params from interview or read from a lab.toml path), solve, attach the Ipopt callback= for AMICODE_ITER + a per-iter plot save, export pulse via JLD2 save. Params live in the script, not AGENTS.md prose (D10).

Acceptance criteria

• The template, run unmodified on Schuster params, produces FINISHED{completed} + a pulse + ≥1 iter_*.png + AMICODE_ITER stats. (S1, S30)
• AGENTS.md documents the param-in-script convention, the run-dir contract the script must emit, and the warm-start (load_pulse) idiom.

Blocked by: none (β.1's run-dir contract informs the template's output calls)

Implementation up at #9 (stacked on #8). The β.3 template vets through the real amico-run at F=0.99999998 (transmon X gate, 16 iter PNGs, pulse.jld2). Scope expanded to the full chat→solve→inspector slice (β.3+β.5): AGENTS.md + template delivered into the opencode session, amico-run on its bash PATH, runs-root reconciled to ~/.amico/runs/default, watcher/inspector reworked to the β.1 contract (FINISHED-keyed). 44+26 tests green. The chat-prompt→script hop is user-verified at the β.6 demo.
