The nightly Mac-coupled bulk ingest was the fragile link (today: Mac slept through 08:00, the pipeline started 09:31, and the sftp bulk pull wedged in timeout cascades holding the db lock — digest blocked behind it). Stage 0 moves the fold onto the box and reduces the Mac to an incremental mirror: - recorder/fold.py (sidecar, capture stays PID 1): closed gz segments -> zstd parquet /data/parquet/<fam>/date=*/segment.parquet, row-parity verified, manifest-logged, THEN gz deleted. Deletion invariant STRONGER: raw needs a verified parquet; parquet needs a Mac ACK before the disk guard may prune it. duckdb capped 384MB; VM 256MB -> 1GB. - recorder/sync_tape.py (com.jaxperro.tape-sync every 15 min + daily.sh): manifest-driven incremental sftp pull, per-file row verify, append into rtds.duckdb NATIVE tables (views-over-parquet rejected: sim's per-asset point queries would crawl), segment-keyed idempotence shared with the legacy ingest.py (kept as fallback), ack back to the box. - recorder/bootstrap_parquet.py: pre-fold history exported to the mirror, parity OK (13.84M trades + 3.07M aux). live/parquet/ is now the complete durable layer Stage 1 (MotherDuck/ClickHouse) would consume. - research/tape.py connect(): brief retry — the 15-min sync holds the write lock for seconds. First run: backlog folded in <60s on the box, 36/36 files mirrored+ verified, rtds.duckdb 13.8M -> 18.2M trades, tape age 24h+ -> ~15-45 min. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
research/ — the edge factory (SILO)
Standing rules (user directive 2026-07-20: "built in a silo to not affect anything on the live bot"):
- Nothing here is imported by, or imports, the bot (
copybot.py,copytrade.py, their configs). The Fly workers run pinned entrypoints; this directory is inert to them. - Tape access is read-only (
duckdb.connect(..., read_only=True)). - The ONE shared write:
live/cache.duckdb::resolutionsvialive/payouts.py— append-only immutable chain facts, the same store the daily pipeline already feeds. Nothing else inlive/is touched. - The existing paper bot is the live test's CONTROL — graduated edges get their own paper harness here, never that one.
- Studies are pre-registered (GitHub issue per study: hypothesis, params,
verdict + kill criteria) BEFORE their forward window opens. Exploration
happens on already-collected tape; verdicts only come from
forward_ledger.jsonlrows dated after the params freeze commit.
