v0.2.0 — resubmit scheduling, epoch decoupling
About SN53 engy
v0.2.0 — resubmit scheduling, epoch decoupling FIXES A LIVE OUTAGE. 0.1.0 pinned EPOCH_S=604800 and a genesis timestamp locally and required the payload's epoch to equal current-1. Neither matched production (epoch_s=86400) or staging (3600), so every payload was rejected as stale-epoch — with no error, no non-zero exit and a healthy heartbeat. Anyone running 0.1.0 is setting no weights at all. Upgrade. Changes: Weights are resubmitted every 120 blocks for the whole epoch instead of once. A validator that submits once per epoch passes activity_cutoff (~16.7h) long before a daily epoch closes and drops out of Yuma consensus. 120 rather than 100 because SN53's on-chain weights_rate_limit is exactly 100, and our anchor is the block read before submitting while the chain's is the block the extrinsic executed in — always later. The validator is no longer epoch-aware. EPOCH_S, epoch_index() and ENGY_SN53_GENESIS_TS are gone; the provider owns the timeline. Replay is bounded by a monotonic guard on local state instead. The last submitted vector is cached and resubmitted during a provider outage, so an outage past activity_cutoff cannot take the validator off chain. Unbounded in time by design: the chain keeps the last weights either way, so stopping costs only our own dividends. A burn paying out to an unexpected owner hotkey is flagged (warning, never a rejection), and a fully-unregistered vector now names its likely cause instead of reading as a chain error. Poll interval 600s -> 300s. Operator notes: ENGY_SN53_GENESIS_TS is no longer read. Leaving it set is harmless. Required config is now just ENGY_SN53_API and ENGY_SN53_MASTER_HOTKEY. ENGY_SN53_RESUBMIT_BLOCKS overrides the 120-block cadence if a subnet's weights_rate_limit ever exceeds it. Known gap: prod genesis is 2026-07-22 00:00 UTC and the first epoch finalizes 25h later, while activity_cutoff is ~16.7h. Validators running from genesis have nothing to submit until then. The fix is provider-side and tracked separ
