Executes activity-core assembly-checkpoint-* runs: fast-forward the
assembly-economics checkout, run its deterministic checkpoints/run_checkpoint.py
(data via web-fetcher, optional llm-connect assessment), commit only
checkpoints/, push fast-forward (rebase once, never force; publish grant
limited to checkpoints/), post assembly_checkpoint. Out-of-window fires are
no-ops (checkpoints/schedule.md is authoritative). Selected by label
'assembly-checkpoint'. Founder-approved 2026-10-12.
