Carry the wire reason phrase through buffered and streaming transport,
response conversion, cache, and Window/Worker Fetch and XHR delivery.
Preserve explicitly empty messages, including HTTP/2 and HTTP/3, and
Latin-1 reason bytes while retaining existing synthetic defaults.
Bump cache metadata to version 4 and keep the original status message
when revalidating an entity with a 304 response. Cover transport modes,
cache reloads, response conversions, and streaming XHR state changes.
Queue each History back/forward/go delta as its own authorized traversal task and resolve the destination when that task runs. Keep the committed traversal position separate from synchronous history mutations, and use the canonical Window history for isolated-world calls. Preserve Navigation API result-bearing traversal behavior.
Cover consecutive and opposite deltas, initially out-of-range requests, synchronous pushState, canceled and reentrant traversals, child documents, and isolated worlds. Update old coalescing assertions and wait for actual browser-owned history commits in protocol tests.
Validation: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo nextest run --no-fail-fast (17584 passed, 13 skipped). Overlapping navigation WPT improves from 16/22 to 18/22, with both new cases passing all 8 subtests. Navigation API comparison preserves all 385 previously passing cases out of 432.
CDP smoke: 41/43 passed. The dom-input FileList upload failure reproduces on the parent binary; puppeteer could not start because Node is missing locally. Artifacts: target/wpt-history-traversal-20260908-lcpQpn/{before,confirmed,navigation-after,cdp,cdp-before}.
Keep request origin independent of URL resolution and referrer context,
including local blob fetches and inherited or sandboxed srcdoc documents.
Reject missing browser origins at the resource client boundary and retain
one Request across Service Worker redirects and network fallback.
Cover dispatch rejection, wire Origin/Cookie headers, memory-cache
partitioning and preserved Service Worker request metadata.
Validation: workspace fmt and Clippy passed; Nextest passed 17,517 tests
with 13 existing skips. Renderer test debug symbols were disabled to fit
available build memory; tests and debug assertions were unchanged.
Publish typed invalidation flags under the environment lock and wake isolate owners only after releasing it. Bound page and worker notification work while preserving command FIFO, teardown safety, and observation ordering.
Remove stale wrapper-era dependencies and terminology, and add mailbox race and CDP burst regressions.
Distinguish network, service worker, and browser-internal redirects so synthetic responses are not subjected to network CORS checks. Preserve every hop for redirect taint and Origin validation, including across navigation response conversions.
Add seven cross-origin service worker script scenarios and guard CORS checks for cached network redirects without ExtraInfo. The new integration regression fails before the fix and passes afterward.
Validated with cargo fmt --all, workspace Clippy across all targets and features with warnings denied, and cargo nextest run --no-fail-fast: 17459 passed, 13 skipped. Used one build job for the full test run after a parallel-build rustc process was killed.
Make process environment owners non-cloneable RAII authorities, share session admission while preserving failed and no-op outcomes, and consolidate duplicate isolate-entry handling. Keep read-only owner queries side-effect-free and add lifecycle regressions.
Remove the Date/Intl wrappers, custom date parser and per-Page replay state. Keep exclusive locale/timezone ownership in a process controller and refresh existing Page and Worker isolates through generation-bound notifications and observation boundaries, including nested Inspector pauses.
Release claims on session/target/context retirement, retain native coercion and locale matching, and cover lifecycle restoration with Rust, BiDi and process-isolated CDP regressions.
Separate combined keyDown character input from rawKeyDown at CDP admission. Dispatch a trusted, cancelable keypress before editing and re-resolve focus after keydown, within the same renderer input turn.
Cover input, textarea, and contenteditable event order, cancellation, typed character metadata, and focus changes. Add a Chromium-calibrated Playwright/raw-CDP smoke while preserving Input.insertText semantics.
Represent the published default page as a target-catalog placeholder with an explicit lifecycle. Materialize it only when an operation needs a live page owner; activate and close the placeholder directly, and create new targets without first constructing the default page.\n\nMake NavigationEngine initialization explicit so read-looking access cannot silently allocate the deferred runtime.
