Operating guide

Feed identical NDJSON bytes through different read partitions and verify incremental decoding, complete-line parsing and explicit EOF completeness outcomes.

Set observable page-state gates and a bounded capture deadline, declare visual transformations, and keep semantic correctness separate from screenshot appearance.

Separate local queue wait from proxy execution and test whether slow projects, retries and recovery respect explicit project protections and shared limits.

Separate accepted submission, status observation, terminal outcome and result-content checks, with bounded polling and recovery that preserves the existing job reference.

Distinguish a browser memory restore from a new proxy request, then check regional state and data freshness against an explicit return-navigation contract.

Check approved query values at each server redirect and client navigation boundary, then verify the owned receiver without claiming analytics attribution.

Test denied, unavailable and timed-out browser location requests separately from proxy-region defaults, and verify that manual area selection remains usable.

Trace a wrong or garbled download name across the final response, page download mechanism and local saved file with controlled regional comparisons.

Build a project usage ledger that separates direct evidence, policy-allocated shared activity and unresolved gaps without claiming unsupported per-project provider billing.

Separate metadata-only HEAD probes from real GET content checks with controlled baseline and proxy requests, correct client method handling and explicit body acceptance.
