Run the full 13,631-case profile on source 112a97e61 with Moli and Chromium
145.0.7632.116 at parallelism 50, using WPT db95fafd1fcef8428805e41eb5705d444e8c67ce.
The case set and fixed scheduling order match the previous full run.
Moli: 9,540 pass, 3,704 fail, 263 timeout, 61 error, 10 crash, 53 harness-stalled.
Chromium: 11,388 pass, 1,897 fail, 242 timeout, 16 error, 18 crash, 70 harness-stalled.
All three JSON module regressions pass on both engines. Relative to 7d9a0a98c,
11 cases gain pass and five lose pass, for a net increase of six.
Keep raw full-run outcomes. Four pass losses pass once on both frozen binaries
in focused diagnostics; SharedWorker-extendedLifetime fails identically in
all three focused runs on each binary, including the pre-fix build.
Validate complete per-engine execution, exact raw/matrix agreement, and sorted,
disjoint, exhaustive status lists. No missing cases or recovery placeholders.
Run the unfiltered all profile against WPT db95fafd1f with Moli built
from 7f9b8b63d (dev, debug=0) and Chromium 145.0.7632.116, using 50 CDP
workers. Both engines execute all 13,631 cases without setup errors,
missing results, or unexecuted recovery placeholders.
Moli: 9,534 pass, 3,708 fail, 264 timeout, 63 error, 52 harness-stalled,
and 10 crash. Chromium: 11,383 pass, 1,899 fail, 242 timeout, 17 error,
72 harness-stalled, and 18 crash.
Compared with the previous lists, 171 cases gain pass and 11 lose pass,
for a net gain of 160. Of the previous refresh's 104 pass losses, 101
now pass, two fail, and one errors. Retain the original full-run
outcomes; separate diagnostic reruns do not replace list statuses.
Validate all eight lists against the raw results and matrix: sorted,
disjoint, exhaustive, and complete. git diff --check passes.
Run unfiltered profile all on WPT db95fafd1fcef8428805e41eb5705d444e8c67ce
with Moli built from 8ba39c4aa1 and Chromium 145.0.7632.116, 50 workers.
Both engines produced results for all 13,631 cases.
Moli: 9,374 pass, 3,686 fail, 260 timeout, 247 error, 54 harness-stalled,
10 crash. Chromium: 11,334 pass, 1,888 fail, 272 timeout, 30 error,
89 harness-stalled, 18 crash.
Complete 91 previously unexecuted cases after a worker exhausted its
restart budget, using the same binary and fixture in bounded batches.
Use their first measured outcomes (63 pass, 26 fail, 2 timeout); preserve
all actual full-run failures and crashes. Both samesite-iframe and
empty-preload-response-body now pass in both engines.
Validate all eight status lists against the raw results and matrix:
sorted, disjoint, exhaustive, with no missing or unexecuted cases.
Compared with the previous refresh, 65 cases gain pass and 104 lose pass
(98 probe errors, 6 failures). Before/after diagnostic rechecks recover
31 of those 104 on the fixed binary; the other 73 also fail or error on
the old binary. Diagnostic retries do not replace full-run outcomes.
Run the unfiltered all profile on Moli c429911cdf and Chromium
145.0.7632.116 using WPT db95fafd1f and 50 CDP workers. Moli was
built from this branch with cargo build --locked (dev, debug=0).
Both engines completed all 13,631 cases without setup errors or
recovery-aborted cases. Keep the existing 13,558 cases and add 73.
Moli: 9,413 pass, 3,687 fail, 264 timeout, 202 error, 55
harness-stalled, and 10 crash. Chromium: 11,380 pass, 1,899 fail,
243 timeout, 19 error, 72 harness-stalled, and 18 crash.
Verify all eight lists are sorted, disjoint, complete and exactly
match the Moli matrix. Preserve the raw statuses, including 200
five-second CDP evaluate probe timeouts. The previous snapshot
used Moli d40181f729; this refresh is not a controlled fixture A/B.
Reconcile the shared HTTP handlers and discovery rules from the split PRs with the complete fixture surface in wpt-misc-fix. Share stash namespaces and XHR dispatch, retain the existing testdriver bridge, preserve raw header values, and carry forward the remaining pipe, template, and dynamic-import regressions.
Validation: 742 Python tests across 74 modules pass; focused Ruff checks and git diff --check pass. With fixed Moli and Chromium binaries, a 27-case WPT comparison against main improves whole-case passes from 7 to 26 and 6 to 23 respectively, with no previously passing case regressing.
Bring the remaining Fetch header fixtures from wpt-misc-fix, including early responses to unread uploads, CORS metadata, response status pipes, and handler discovery. Consolidates d210a13a5d and 8e2764e6cd with their current regression tests.
Implement preload/resources/preload-count.py and admit its exact references
during case discovery. Resource requests increment a shared counter and fail
with 404; result requests return JavaScript and consume the count. This lets
the unsupported-type WPT verify that no preload request was sent.
Validation: 432 Python WPT tests across 31 modules, run with 32 workers.
Moli and Chromium both pass the affected WPT and the two related MIME cases
(47 subtests per engine). Only Python and the WPT pass ledger changed.
(cherry picked from commit b8a3d0497d3575200ce28896c8bcde7f8c4719c4)
Serve Fetch redirect.py with upstream Origin and credentials responses,
preflight handling, query inheritance, counters, delays and form status codes.

against upstream wptserve, including byte parsing and unread request bodies.
(cherry picked from commit 813bb1b3ecb4e55c5a0167df22494ca5269b1ef1)

Location, delay, and method behavior. Preserve raw request URIs and allow
redirect responses before the upload completes.

fixtures through real HTTP requests.
Validation: all 510 benchmark unit tests pass. With the unchanged Moli
binary, 17 WPT cases improve from 6 to 9 passes and 72 to 79 passing
subtests; both redirected Worker harnesses now execute their assertions.

Validation: all branch checks passed. Ran 329 tests in 129.466s; OK
(cherry picked from commit 252861d9c8)

(cherry picked from commit 807abbe05b)
Model service worker script redirects, versioned imports and update response sequences, including file-based and installation updates. Preserve request methods, cache metadata, raw script bytes and per-resource state shared across fixture origins.
(cherry picked from commit 5d0ddf013b)
Model xhr/resources/headers.py with its duplicate, empty, cookie and non-ASCII response headers. Include HEAD behavior and precise fixture discovery regression coverage.
(cherry picked from commit 8557f41b0c)
Serve malformed chunk framing and the upstream infinite redirect loop instead of Python source. Preserve raw partial body delivery, origin and query parameters, HEAD semantics, and exact fixture discovery.
Source: 0de7826105
(cherry picked from commit 0f4acf2725)
Consolidate #552 and #938 on top of the IDNA and nested-domain support already in main. Preserve the requesting host for location templates and use web-platform.localhost in the cross-engine runner.
Expand WPT domain and host templates for configured Unicode labels, nested subdomains and alternate hosts using IDNA output. Leave unknown template keys and non-template response bytes unchanged. Tests exercise response bodies, headers and one-pass request substitutions.
Validation: all branch checks passed. Ran 324 tests in 125.691s; OK
Support remote-context executor pages and dispatcher queues, including atomic FIFO messages, request-header forwarding, CORS and response pipes. The branch includes the minimal shared response/body helpers it needs and does not depend on the iframe-stash branch. Tests cover wire behavior, concurrent queue operations and case selection.
Validation: all branch checks passed. Ran 336 tests in 134.129s; OK
Require enable-cors and a nonempty Origin before exposing CORS response headers from common/redirect.py. Preserve the first status and Location values, handle extension methods, and respond without waiting for unused uploads or adding a Content-Length header.
Validation: 580 Python tests passed with 32 workers; 1296 HTTP responses matched official wptserve for status, body, and 15 response fields. New regression tests fail on the unmodified main baseline.
Source-commit: 99b528aece
Run the full all profile on Moli d40181f729 and WPT db95fafd1f with 50 CDP workers. All 13,558 cases completed: 9,494 pass, 3,744 fail, 255 timeout, 50 harness-stalled, 14 error, and 1 crash. Compared with the prior lists, 443 gained pass and 39 lost pass.
