## Caveats

- GitHub Actions/Review Runners, not always-on generic VM (engine classifies the "ci" regime as a CI runner, so non-CI workloads see it as a different kind of product; no alt flag). Ubuntu 24.04, 5th-gen AMD EPYC. Advertised unlimited concurrency; job/session maximum not verified.
- GPU rates include 4 vCPU/16 GB/100 GB host, not add-on rates. GPU access requires contacting provider; H100 coming soon, excluded from numerical rate list.
- Do not apply advertised performance/TFLOPS savings as universal wall-clock discounts.
- Null values mean unknown, not free/unlimited. No model-token cost, tax or unverified ancillary charge included.
- Native browser/device/task/credit prices with unknown CPU/RAM are deliberately non-priceable. Check regime before interpreting any partial resource estimate.
- 2,000 free runner minutes in the first month (no card; no rollover).

## Verified billing facts and gotchas

1. GitHub Actions/Review Runners, not always-on generic VM; CPU mode alt. Ubuntu 24.04, 5th-gen AMD EPYC. Advertised unlimited concurrency; job/session maximum not verified.
2. GPU rates include 4 vCPU/16 GB/100 GB host, not add-on rates. GPU access requires contacting provider; H100 coming soon, excluded from numerical rate list.
3. Do not apply advertised performance/TFLOPS savings as universal wall-clock discounts.

## Worked example

Requested: 4 vCPU/8 GiB, 50 simultaneous × 8 h/day × 22 days = **8,800 instance-hours**, 30% CPU; 50 GiB snapshots and 100 GiB egress. A month is 730 hours only when explicitly used in rate conversion.

4 vCPU/16 GB runner fits requested 4/8: 8,800×$0.48=$4,224 CPU-runner usage. No performance multiplier assumed. Eight-hour jobs, 50 parallel runners and arbitrary retained snapshots still require validation; snapshots and egress not priced.

Page captures and documentation indexes/bundles are in `raw/`; provider JSON lists the evidence paths. HN query results were captured separately as `<id>--hn.txt`; they are discovery leads, not current tariff authority. Downloaded docs do not imply every feature was verified; unsupported assertions remain null.
