Greptile Summary

This is an automated daily update that records newly observed feature gate activation epochs on Solana's mainnet, testnet, and devnet networks into feature-gates.json.

• 2 mainnet activations: SIMD-0340 (validate chained block id) and SIMD-0178/0189/0377 (SBPFv3) both land at epochs 992 and 993 respectively; the encompassing SIMD-0340 check (vcmrw431…) also reaches mainnet at epoch 992.
• 2 devnet activations: SIMD-0512 (sol_sha512 syscall) at epoch 1092, and SIMD-0291 (commission rate basis points) at epoch 1093.
• 3 testnet activations: SIMD-0357 (Alpenglow VAT) at epoch 979, SIMD-0449 (direct account pointers) at epoch 981, and the SIMD-0186 amendment at epoch 980.

Confidence Score: 5/5

Safe to merge — all changes are additive epoch updates recorded by automated tooling with no logic or schema changes.

Every changed field is a previously-null activation epoch replaced with a positive integer, consistent with values for equivalent fields on other feature gates already in the file. The JSON structure is unchanged, and the epoch numbers follow the same ordering patterns as existing fully-activated entries.

No files require special attention.

Important Files Changed

Filename	Overview
app/entities/feature-gate/feature-gates.json	8 activation epoch fields updated from null to concrete values across 7 feature gates; changes are structurally valid JSON and follow the established testnet → devnet → mainnet progression pattern seen throughout the file.
