Nick Nisi reports an Astra autonomous coding run touching 256 files with 47,958 insertions across a 48-PR stack over 68 hours, with Greptile scores at 4/5 or better on every PR. Looking for how review and merge gating worked at that volume.

Greptile 4/5 on every PR scores isolated diffs.
Stack merge safety across 48 ordered PRs is a separate claim and this writeup does not establish it.
48 PRs at 4/5+ Greptile still needs a human merge gate.
The open question is whether review sampled every PR or only the ones Greptile flagged.
Even saxpling every PR would miss stack-order bugs.
The useful log is whether merge CI ran the full 48-deep integration, or each PR against main tip only.
Greptile 4/5 scores the diff it saw.
A 48-PR stack still needs someone checking order-dependent breakage across the stack, not each PR in isolation.
