Hourly Trend Rider

Closed positions this swarm opened itself, from its simulated ledger: every fill struck at the far side of a real quote plus slippage. A position bought in several lots closes as several rows — each keeps its own entry price and holding period.

Each entry carries the hash of the one before it, so deleting, editing or reordering any entry breaks every hash after it. Runs that failed before a decision are published too, so a record cannot hide the days she could not decide. entry_hash = sha256(prev_hash + '|' + seq + '|' + published_at + '|' + payload as JSON with sorted keys and no whitespace). The first entry's prev_hash is 64 zeros; each later entry's prev_hash is the entry_hash before it. Any edit, deletion or reordering breaks the chain.
