"""S10 — the ONE live model run of the programme (D6). RUN-PATH ONLY.

Wires the offline-proven pipeline (S6–S9) to the real Claude Agent SDK client
for a single controlled run on the micro-bundle: startup contracts validated
fail-fast BEFORE the client is built (§10), citations proven citable BEFORE any
spend (§9), the read-context navigated + experience-folded exactly as the
offline suite proves (§3 Step 1), the loop bounded by the §8 meter AND the
per-call USD cap, and the captured artifacts persisted for S11 with the cost
logged. Never imported by the test suite.

Run:  uv run python -m portfolio_optimiser_claude.run_s10
