Carry received HTTP reason phrases from the parser through buffered and streaming responses, disk and memory caches, page responses, Fetch, and XHR. Preserve custom and empty HTTP/1 phrases and report empty text for HTTP/2 and HTTP/3. Synthesized responses retain canonical fallback. Regressions cover whitespace, non-ASCII bytes, and cache round trips.

Propagate an unhandled nested worker exception to the parent worker with ErrorEvent.error set to null, as required by omitError reporting. Update the existing end-to-end parent onerror regression to inspect the null value while retaining filename, line, column, and message checks.
Convert getComputedStyle Element and nullable pseudo-element arguments through the shared WebIDL derive path in main, iframe and popup windows. Preserve conversion exception identity and prevent pseudo-element conversion for invalid element receivers. Regression fixtures cover cross-realm genuine elements, author proxies and thrown coercions. Retain current window receiver and scrolling infrastructure. Determine expected intrinsics from the actual binding function realm while retaining main, iframe and legacy popup document coverage. Treat disconnected child-frame and popup targets as empty before consulting cached context state. Retained style objects update across connection and removal; the 318-assertion matrix keeps all original conversion checks.
Validate DOMImplementation native receivers before argument conversion, and convert createDocument qualifiedName before its nullable DocumentType argument. Allocate factory results in the owner Document relevant realm after conversion, preserving the callee realm for conversion errors. Cross-realm regressions cover genuine and forged doctypes, author proxies, conversion order, and factory result ownership.
Return Document.rootElement from the current native document element only when it is an SVG-namespaced svg root. Retain wrapper identity in the Document owner realm without reading author-overridable properties. Regressions cover root replacement/removal, adoption, cloning, namespace/case distinctions, cross-realm access and registered native Document Proxies.
Add an incremental XHR text/document decoder that distinguishes text, XML and HTML response kinds. BOM precedence, transport charset, XML declarations and HTML sniffing retain state across arbitrary chunk boundaries. Native unit tests cover all split points and truncated input. This PR adds the decoder API; switching every XHR producer to it is separate work.
Group ignored reasons, values and nonempty properties behind one optional box. Use nonzero backend IDs and serialize fixed role/name kinds on demand, reducing the common AX node from 296 to 96 bytes while preserving payload shape and field order.
Add reproducible CLI and native construction benchmarks. Generated 40000-row text dumps use 382.6 to 341.5 MiB peak RSS; 200000-row text dumps use 1753.5 to 1612.8 MiB. Record the roughly 5.5 percent native construction cost for dense ignored nodes alongside the memory gains.
Validation: cargo fmt --all; workspace clippy with all targets/features and warnings denied; cargo nextest run --no-fail-fast (19890 passed, 17 skipped). All 188 formal benchmark samples match their corresponding before/after outputs.
Large semantic dumps retain a JSON object graph with allocated field names
and string node references for every AX node before formatting the output.
Build compact typed nodes with numeric references and pass them directly
from the renderer to the CLI. Keep one AX traversal for both typed nodes
and CDP payloads, converting protocol nodes individually as they are built.
Preserve omitted/empty fields, field insertion order, list markers, and
frame-root attachment order. Render text iteratively and trim in place.
Add compatibility coverage and a standalone benchmark that stages both
executables on the same filesystem, alternates runs, records peak RSS and
wall time, and rejects changes to dump output bytes.
Against main at 5f5e1fff3 on a generated 40,000-row list (three interleaved
runs, medians):
- semantic_tree_text: 718.42 -> 390.96 MiB; 2.919 -> 2.204 s.
- semantic_tree: 815.71 -> 483.81 MiB; 2.484 -> 2.369 s.
- markdown control: 95.52 -> 95.59 MiB; 0.895 -> 0.913 s.
A generated 200,000-row list also completes with identical bytes (one run):
- semantic_tree_text: 3473.02 -> 1775.07 MiB; 13.245 -> 10.015 s.
- semantic_tree: 3803.45 -> 2137.26 MiB; 12.626 -> 10.397 s.
JSON/text comparisons also match the baseline on a mixed fixture containing
hidden/ignored nodes, form values, list markers, shadow DOM, and child frames.
These generated fixtures are independent of the external MOL-269 evidence.

Use computed style facts for content-visibility locks instead of reading
inline declarations. Hidden-until-found and stylesheet-hidden contents
stay out of innerText until revealed or overridden by the CSS cascade.
Remove the obsolete inline-only readers and cover hidden-until-found,
boolean hidden, synchronous reveal, and important stylesheet overrides.
Fixes MOL-113.
Add borrowed AllowShared BufferSource conversion for algorithms that copy after dictionaries are converted, including native range writes and atomic shared-memory byte access. Reject resizable/growable storage and author proxies using native identity, including detached resizable buffers and views. Tests cover late snapshots, bounded writes, surrounding bytes, detachment and native resizable flags. Individual API migrations are separate.
Refresh all-profile WPT Cross lists from Moli 1.1.16 release at 23c6bb5754
against WPT db95fafd1f, using CDP with 50 workers. Each of 13,631 cases
ran once: 9,674 pass, 3,656 fail, 253 timeout, 37 harness-stalled,
10 error and 1 crash. Pass count rises by 86 (132 gained, 46 lost).
Review all 46 lost passes against the previous snapshot's binary:
41 stable version regressions, 2 existing flaky cases, 1 existing runner
readiness race and 2 cases failing in both versions. Preserve original
full-run outcomes in the lists. Validate exact report agreement, sorted
disjoint coverage and no missing cases; git diff --cached --check passes.

Query dialogs on the addressed Page when waiting for navigation lifecycle milestones. Allow independent page load completions to advance while another page has a blocked load.
Cover normal and eager navigation with gated two-window regressions, eager recovery after accepting an alert, and dialog ownership across DevTools attachments.
While a JavaScript dialog is open, the scheduler no longer waits for the
page load to finish. WebDriver Classic commands using the normal and eager
page load strategies now return, and the session stays usable.
Fixes#809
Resolve em and ex SVG lengths in disconnected documents using the initial computed font style. Keep live styled elements on their existing resolved-style path. Regressions cover detached HTML and XML documents, child realms, and inherited fonts. Extract the existing context resolver for reuse by the initial-font path; preserve live-element resolution unchanged. Factory-created lengths have no associated element, so their font basis remains initial when the factory is styled or removed.
Add native Fetch referrer selection and inheritance without changing request origin, cookie initiator or network partition. Apply the effective policy to the selected referrer when building outgoing headers, preserve explicit omission and about:client fallback, and copy policy to derived requests without copying integrity. Unit tests cover header selection, sanitization and request identity.

Use a separate equivalent path for distance queries on rectangles and ellipses with one zero axis. Preserve their starting points and sweep while retaining empty rendered bounds. Core regression tests verify total length, endpoint and intermediate point queries, and distinguish fully empty geometry from a shape collapsed along one axis.
Add the native DOMString value representation that preserves unpaired UTF-16 code units and exposes a scalar projection for native consumers. Equality and hashing retain original units; parser scalar appends preserve allocation capacity. Unit coverage includes surrogate identity and append boundaries. This PR provides the native value API; migrating all DOM producers is separate work.
Add an explicit unrestricted_float converter to the shared WebIDL value and derive infrastructure. Preserve signed zero, NaN and infinities while rounding finite numbers to binary32; required arity, conversion side effects and original exceptions retain the existing contracts. Cross-realm tests compare Math.fround and check callee-realm TypeError.
