▸ VALIDATION STATUS · STAGED MAINNET SOAK

Where the v2.0 soak stands.

ReserveGrid OS v2.0 Invariant Shield is in staged validation. This page tracks the soak in motion, what has cleared, and what remains gated on a real-bitcoind run or a pool-side design partner. Numbers update as each checkpoint lands.

AS OF · 2026-05-05

Setup A · Shadow soak

○ Pending

Synthetic mempool feed against a docker-compose mirror of the verifier stack. The intended pass criterion was zero Class M tolerance breaches across the full window. Forensics on 2026-07-22 found the Invariant Shield skipped every template, so the criterion never ran: this window yields no evidence about v2_invariant_mempool_tolerance_exceeded either way.

Setup B · Real-bitcoind soak

○ Pending

Class S and Class D check chain against a real mainnet bitcoind under live template flow. A hardened re-soak is running: T+0 2026-07-22, T+7 wrap 2026-07-29, with evidence written outside the soaked process so it survives container death. It exercises mempool-view infrastructure and Phase 1 policy only. The Class M criterion stays unexercised until the template sender ships raw_block_hex, so no Class M evidence exists yet.

Blocked on

PB-19 (raw_block_hex on the wire), then a fresh soak asserting shield_skipped == 0 at T+0.

Setup C · Pool-side design partner soak

○ Pending

Live template stream from a participating Stratum V2 pool, mirrored into the verifier in shadow mode. Treats the pool as the source of truth and the verifier as a second pair of eyes; the only path to evidence on real-world template traffic.

Blocked on

Design partner. Pool operator interest required.

Phase 1.5 · Tier 3 invariant wiring

○ Pending

Wired 2026-07-22. All seven Tier 3 invariants (coinbase_script_length, coinbase_output_count, weight_exceeds_max, sigops_exceed_max, nontcb_null_prevout, header_version_low, duplicate_tx) are implemented and tested behind the shield facade, bringing the Invariant Shield to 18 of 18 ADR-002 invariants running. Wired is not validated and not yet merged: the change sits on branch, and the merge to main is sequenced after the in-flight re-soak wraps.

Blocked on

Re-soak wrap 2026-07-29, then merge to main.

▸ DESIGN PARTNER PROGRAM

Setup B and Setup C are open.

If you operate a Stratum V2 pool and want a second pair of eyes on your template stream, the design-partner slots for Setup B and Setup C are open. Shadow mode first, no enforcement on the wire, full evidence trail in your own observability stack. The output of this work is a public soak report and the operator keeps everything that runs in their own infrastructure.
