Open competition miner bundle v1 (feed config + pinned artifacts)
About SN78 Umi
Signed feed configuration and pinned runtime artifacts for the SN78 open competition, as promised in OPEN_COMPETITION.md. Start here: COMPETITION_MINER_ADDENDUM.md. It applies on top of the reference miner runbook. If you already run the reference miner in inactive_shadow, this is a wiring change, not a rebuild. Supported targets: aarch64-apple-darwin, x86_64-unknown-linux-gnu. ARM64 Linux is not yet published. Verify before use: shasum -a 256 -c SHA256SUMS transport-policy.json must hash to d030da694b5dd8d0e02c4c5a9d607107ed54d8feec47e2ea0e7f6b1070630168. Both verifier binaries are additionally pinned inside that policy and re-checked by the miner at startup. SHA256SUMS is signed (sr25519) by the release authority 5DPEtjXkt9y216Mc6u8jNcM69ULppSCvpys5sUHxtVf2ebkS; see SHA256SUMS.sig. Correction to an earlier notice: the cohort cadence is round_stride_blocks = 2880 blocks (about 9.6 hours), not 1440 (about 4.8 hours).
