Refuse-to-release is the product.
Released days are the only days for sale. The chain below runs nightly on every completed UTC day — five gates, in order. A day that fails any gate is not released; we recover it and re-run, and every correction is dated on the ledger.
What runs, what it checks, what makes it fail.
Close gates
Per selector, expected market windows are compared against what was observed — including the evidence-gated venue_unlisted disposition. 100ms coverage floors and freshness lineage are checked on every aligned row.
On-chain trade reconciliation
Every Polymarket trade partition is proven against Polygon OrderFilled events. Every trade row carries the transaction hash it was matched to, so you can re-check it yourself on-chain.
Artifact audits
Schema contracts, timestamp walls (no lookahead: receive ≥ event), value domains, manifest row counts and SHA256, and stable-ID uniqueness are all enforced against the written file.
Durable mirror + verification
Files are mirrored to object storage and re-verified by their SHA256 metadata — never by trusting storage ETags. Hundreds of files per day, every one re-checked after the copy.
Gapless promotion gate
Day D is refused unless D-1 is already released. The archive can only advance one contiguous day at a time — a customer never hits a missing day between inception and the latest release.
One contiguous run. No silent gaps.
The D-1 rule holds the archive to a single unbroken run. When a day goes red we recover it and re-run the whole chain — pre-customer re-inceptions have happened and are listed below, in plain language.
Every withdrawal and disclosure, dated.
We publish what we withdrew and why. venue_unlisted is recorded as evidence — a venue-side fact with a timestamped transcript — never as an apology for our own gap.
| Date | Scope | Type | Reason & action |
|---|---|---|---|
| 2026-07-14 | Polymarket Up/Down · 5-minute windows | RE-INCEPTION | Withdrew 2026-07-10 and 07-11 after 2026-07-12 carried Up/Down windows the venue never created. The chain re-incepted at 2026-07-13, and no customer ever held a withdrawn day — these were pre-customer. action → inception reset → 2026-07-13 |
| 2026-07-12 | Polymarket Up/Down · 5-minute windows | VENUE_UNLISTED | The venue never created nine expected 5-minute windows. We disclose this as a venue fact, never as our data — and only with recorded proof that we watched for the window across its whole life.

| 2026-07-09 | Polymarket broad · census | RE-INCEPTION | Withdrew the certified 2026-07-07 and 07-08 when 2026-07-09 proved unrecoverable — a broad-universe census gap. Recovered and re-incepted rather than ship a break in the chain. action → inception reset |
