fix: intermittent CI failure is-not-alwaysOnTop (#51133)

* fix: intermittent CI failure is-not-alwaysOnTop

Ensure that the `always-on-top-changed` event always fires with the
right 'alwaysOnTop' boolean, regardless of interaction between
SetZOrderLevel() and MoveBehindTaskBarIfNeeded(). We know what the
value will be when all of the HWND events settle, so use that value.

-description: Given a Chrome Releases blog post URL (chromereleases.googleblog.com), extract every CVE/bug and find the underlying Gerrit CL that fixed it by searching the local Chromium checkout and sub-repos. Use when asked to map Chrome security release notes to fixing CLs, or to find which commits correspond to CVEs in a Chrome stable update.
----
-
-# Chrome Release → Fixing CL Mapper
-
-Maps every security fix in a Chrome Releases blog post to the Gerrit CL(s) that fixed it.
-
-## Input
-
-`$ARGUMENTS` — a `https://chromereleases.googleblog.com/...` URL. If empty, ask the user for one.
-
-## Procedure
-
-### 1. Extract CVE → bug ID pairs from the blog post
-
-The blog HTML buries bug IDs inside `<a>` tags, so strip tags first. Run:
-
-```bash
-curl -sL "$URL" | python3 -c '
-import sys, re, html
-t = re.sub(r"<[^>]+>", " ", sys.stdin.read())
-t = re.sub(r"\s+", " ", html.unescape(t))
-seen = set()
-for m in re.finditer(r"\[\s*(\d{6,})\s*\]\s*(Critical|High|Medium|Low)\s*(CVE-\d{4}-\d+):\s*([^.]+?)\.", t):
-    if m.group(3) in seen: continue
-    seen.add(m.group(3))
-    print(f"{m.group(3)}|{m.group(1)}|{m.group(2)}|{m.group(4).strip()}")
-' > /tmp/cve_bugs.txt
-cat /tmp/cve_bugs.txt
-```
-
-If this yields nothing, the page may have changed format — fall back to `grep -oE 'CVE-[0-9]{4}-[0-9]+'` and `grep -oE 'crbug\.com/[0-9]+'` and pair them by order.
-
-### 2. Find the fixing CL for each bug
-
-Search git history in the Chromium checkout and relevant sub-repos for commits whose `Bug:` or `Fixed:` footer references the bug ID, then extract the `Reviewed-on:` Gerrit URL.
-
-Repo selection by component keyword:
-- ANGLE → `third_party/angle`
-- Skia, Graphite → `third_party/skia`
-- PDFium → `third_party/pdfium`
-- Dawn → `third_party/dawn`
-- V8, Turbofan, Maglev, Turboshaft → `v8`
-- everything else → `.` (chromium/src)
-
-Always also fall back to `.` if the hinted repo has no match.
-
-```bash
-cd /root/src/electron/src   # chromium root (parent of electron/)
-
-lookup() {
-  local bug="$1" repos="$2"
-  for repo in $repos . v8 third_party/skia third_party/angle third_party/pdfium third_party/dawn; do
-    local hits
-    hits=$(git -C "$repo" log --all --since='6 months ago' -E \
-           --grep="(Bug|Fixed):.*\\b${bug}\\b" --format='%H' 2>/dev/null | sort -u)
-    [[ -z "$hits" ]] && continue
-    while read -r h; do
-      git -C "$repo" log -1 --format='%B' "$h" | grep '^Reviewed-on:' | sed 's/^/    /'
-      echo "      ↳ $(git -C "$repo" log -1 --format='%s' "$h")"
-    done <<<"$hits"
-    return 0
-  done
-  echo "    (not found locally)"
-}
-```
-
-Drive it from `/tmp/cve_bugs.txt`. Prefer the **non-`[M1xx]`-prefixed** commit subject as the canonical main CL; the `[M1xx]` ones are branch cherry-picks.
-
-### 3. Handle misses
-
-For any bug with no local hit:
-- `git -C <repo> fetch origin` then re-search `--remotes` (fix may be newer than the checkout).
-- Query Gerrit directly: `curl -s "https://chromium-review.googlesource.com/changes/?q=bug:${BUG}&n=10" | tail -n +2 | python3 -m json.tool` (also try `skia-review`, `pdfium-review`, `dawn-review`, `aomedia-review`).
-- **`b/` bug format (Skia, Graphite, Dawn):** These repos reference bugs as `b/<id>` in commit messages rather than `Bug: <id>` footers. The Gerrit `bug:` query will return nothing. Use `message:<id>` search instead:
-  ```bash
-  curl -s "https://skia-review.googlesource.com/changes/?q=message:${BUG}&n=5" | tail -n +2
-  ```
-  Apply the same pattern for `dawn-review.googlesource.com` when the component is Dawn.
-- **Tracing main CLs from merges:** When only `[M1xx]` merge CLs are found, query the CL detail for `cherry_pick_of_change` to find the original main CL number:
-  ```bash
-  curl -s "https://chromium-review.googlesource.com/changes/${CL_NUM}?o=CURRENT_REVISION" | tail -n +2 | python3 -c "
-  import sys, json
-  d = json.load(sys.stdin)
-  print(d.get('cherry_pick_of_change', 'none'))
-  "
-  ```
-- If still nothing and the bug was reported very recently (especially by "Google Threat Intelligence" or marked in-the-wild), the CL is likely still access-restricted — report it as such rather than guessing.
-
-### 4. Special cases
-
-- **Roll CLs — skip and find the upstream fix:** For components whose fixes land in upstream repos (PDFium, Dawn, Skia, Graphite, libaom, libvpx, ffmpeg), the chromium-review hit will be a `Roll src/third_party/...` commit. Do not report the roll CL as the fix. Instead, query the component's own Gerrit instance directly for the actual fixing CL:
-  - PDFium → `pdfium-review.googlesource.com` (use `bug:` or `message:` query)
-  - Dawn → `dawn-review.googlesource.com` (use `message:` query — uses `b/` format)
-  - Skia / Graphite → `skia-review.googlesource.com` (use `message:` query — uses `b/` format)
-  - libaom → `aomedia-review.googlesource.com`
-  
-  Only if the upstream Gerrit instance returns no results should you fall back to reporting the roll CL — in that case, include the roll CL and note that the actual fix is upstream but the specific CL could not be identified.
-- Multiple `Reviewed-on:` lines in one commit body: cherry-picks keep the original line plus a new one. The **first** `Reviewed-on:` is the original CL.
-- A bug may have multiple distinct fix CLs (fix + follow-up hardening) — list all of them.
-
-### 5. Output
-
-Produce a markdown table per severity level: `CVE | Bug | Component | Fix CL (main)`. Link bugs as `https://crbug.com/<id>`. Save raw output (including all branch merges) to `/tmp/cve_cls.txt` and mention the path.

-description: End-to-end Chrome security backport for an Electron release branch. Given a Chrome Releases blog URL and a branch (e.g. 41-x-y), determines which CVE fixes are missing from the *actual synced source*, writes the cherry-pick patches locally, validates them with `e sync --3` + `lint --patches`, then pushes a single PR. Use when asked to backport a Chrome security release to N-x-y, "is CVE-X already in N-x-y?", or to produce/validate the cherry-pick set for a release branch.
----
-
-# Chrome Release → Validated Backport PR
-
-Input: `$ARGUMENTS` = `<release-branch> <chrome-releases-blog-url>` (e.g. `41-x-y https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop_15.html`). Ask if either is missing.
-
-The flow is **local-first**: nothing is pushed until every patch applies via `e sync --3` and passes `lint --patches`.
-
-## 1. Map CVE → bug → fix CL
-
-Run `/chrome-release-cls <blog-url>` (or its inline procedure) to produce `/tmp/cve_bugs.txt` (`CVE|bug|severity|desc`) and a per-bug canonical fix CL. For each CL also note `repo` (path under `src/`: `.`, `v8`, `third_party/{skia,angle,pdfium,dawn}`, `third_party/libaom/source/libaom`) and `gerrit-host`.
-
-**Prefer the target-milestone merge CL** if one exists (e.g. on `41-x-y` ≈ M146, prefer the `[M146]` cherry-pick over the main CL) — it's already rebased and far less likely to conflict. Find it via `git log --all --grep` on the Change-Id, or Gerrit `?q=bug:<n>`. If Chrome did *not* merge a fix to the target milestone, that's a strong signal the vulnerable code doesn't exist there — flag it for skip rather than forcing a port.
-
-## 2. Prepare a synced worktree
-
-Reuse `bp-<NN>` from `e show configs` if present, else `e worktree add bp-<NN> ~/src/electron-bp-<NN> --source <current> --no-sync`.
-
-```bash
-cd <root>/src/electron
-git fetch origin <branch>
-git checkout -B security-backport/<branch>/<short-date> origin/<branch>
-e use bp-<NN>
-e sync 2>&1 | tee /tmp/bp_sync.log
-```
-
-If sync fails with `NotADirectoryError: '<root>/src/.git/objects/info/alternates'`, remove `GIT_CACHE_PATH` from the bp config's `env` and retry.
-
-## 3. Verify IN-TREE vs NEEDS-BACKPORT
-
-For each bug, three checks against the **synced** repo:
-
-1. `git -C "$repo" log HEAD --since='1 year ago' -E --grep="\b${bug}\b" --format='%h %s'`
-2. Fetch Change-Id from Gerrit, then `git log HEAD --grep="^Change-Id: ${cid}$"`
-3. `grep -rlE "(\b${bug}\b|${cid})" <root>/src/electron/patches/`
-
-Any hit ⇒ IN-TREE. All empty ⇒ NEEDS-BACKPORT.
-
-For each NEEDS-BACKPORT CL, also fetch its file list (`/changes/<proj>~<cl>/revisions/current/files`) and **skip** if every file is under `chrome/browser/`, `chrome/android/`, `ios/`, or `components/**/android/` — Electron doesn't compile those.
-
-Report the table now (`CVE | Sev | Bug | Component | Verdict | CL`) and the proposed backport set; get user sign-off before continuing.
-
-## 4. Write patches locally (no push yet)
-
-For each backport CL, fetch the raw patch and write it into `patches/<dir>/`:
-
-```bash
-curl -s "https://${host}.googlesource.com/changes/${proj//\//%2F}~${cl}/revisions/current/patch" \
-  | base64 -d > "patches/${dir}/cherry-pick-${short}.patch"
-echo "cherry-pick-${short}.patch" >> "patches/${dir}/.patches"
-```
-
-For repos with no Gerrit host `e cherry-pick` supports (e.g. **libaom** on aomedia), instead `git cherry-pick` the upstream commits onto the synced sub-repo HEAD and `git format-patch` the result.
-
-For any newly-created `patches/<dir>/`, append to `patches/config.json` **preserving the compact one-line-per-entry style**:
-
-```json
-  { "patch_dir": "src/electron/patches/<dir>", "repo": "src/third_party/<dir-or-nested-path>" }
-```
-
-## 5. Validate with `e sync --3`
-
-```bash
-e sync --3 2>&1 | tee /tmp/bp_sync3.log
-```
-
-On `Patch failed at NNNN <subject>`:
-
-- `cd` into the failing repo, inspect `git diff` for conflict markers.
-- **Test-only files** (e.g. `web_tests/VirtualTestSuites`, `*_unittest.cc` context drift): take ours (`git checkout --ours -- <file>`) if the security-relevant hunks merged cleanly.
-- **Substantive code conflicts**: check whether a target-milestone merge CL exists and swap to it. If none exists upstream and the surrounding code is structurally different, **drop the patch** (delete the file, remove from `.patches` and `config.json`) and note it for a separate manual-port PR — do not improvise security-fix semantics.
-- After resolving: `git add <files> && git -c commit.gpgsign=false am --continue`, then `e patches <repo>` to export the resolved patch, then re-run `e sync --3`. Repeat until clean.
-
-## 6. Export → lint → re-apply loop
-
-```bash
-e patches all
-node script/lint.js --patches   # must exit 0
-```
-
-If lint reports findings (typically trailing whitespace on `+` content lines), fixing them **changes the bytes the patch writes**, which invalidates the `index <old>..<new>` blob hashes that `e patches` baked in. Hand-editing a `.patch` and pushing it as-is will pass lint locally but fail CI's Apply Patches re-export check with a one-line `index` hash diff.
-
-So whenever lint (or you) modifies any `.patch` file after export, round-trip once more:
-
-```bash
-# fix the lint findings in patches/**/*.patch, then:
-e sync            # re-apply the edited patches (no --3 needed; they applied cleanly last time)
-e patches all     # re-export so index blob hashes match the edited content
-node script/lint.js --patches      # must now exit 0
-git diff --quiet -- patches/ || { echo "patches changed again — repeat the loop"; }
-```
-
-Repeat until `lint --patches` exits 0 **and** `git diff -- patches/` is empty after the final `e patches all`. Only then is the patch set CI-stable.
-
-## 7. Commit, push, PR
-
-```bash
-git add patches/
-git commit -m "chore: cherry-pick <N> changes from <dirs>"
-git push origin HEAD
-gh pr create --repo electron/electron --base <branch> --head <this-branch> \
-  --title "chore: cherry-pick <N> changes from <dirs>" \
-  --label "<branch>" --label backport-check-skip --label semver/patch --label "security 🔒" \
-  --body-file /tmp/pr_body.md
-```
-
-PR body format:
-
-```markdown
-Backports the following changes:
-
-* [`<shortCommit>`](<gerrit-CL-url>) from <patchDir> — <subject> ([<bug>](https://crbug.com/<bug>), CVE-YYYY-NNNN)
-* ...
-
-Notes: Security: backported fixes for CVE-YYYY-NNNN, CVE-YYYY-NNNN, ....
-```
-
-Short commit links to the **Gerrit CL**; bug links to `crbug.com`; CVE comes from the blog mapping (the patch's own `Bug:` footer may differ); `Notes:` is the last line. Mention any dropped patches (with reason) above the `Notes:` line.
-
-Restore `e use <previous>` when done.

 # Electron Node.js Upgrade: Phase One
@@ -174,127 +174,10 @@ When the error is in Electron's own source code:
 1. Edit files directly in the electron repo
 2. Commit directly (no patch export needed)
 
-# Electron Node.js Upgrade: Phase Three
-
-## Summary
-
-Run the Node.js test suite via `script/node-spec-runner.js`, fix failing tests, and commit fixes until all tests pass. Certain tests are permanently disabled (listed in `script/node-disabled-tests.json`) and should not be run.
-
-Run Phase Three immediately after Phase Two is complete.
-
-## Success Criteria
-
-Phase Three is complete when:
-- `node script/node-spec-runner.js --default` exits with zero failures
-- All changes are committed per the commit guidelines
-
-Do not stop until these criteria are met.
-
-## Context
-
-Electron runs a subset of Node.js's upstream test suite using a custom runner (`script/node-spec-runner.js`). Tests are executed with the built Electron binary via `ELECTRON_RUN_AS_NODE=true`. Many tests need adaptation because Electron uses BoringSSL (not OpenSSL) and Chromium's V8 (which may differ from Node.js's bundled V8).
-
-**Key files:**
-- `script/node-spec-runner.js` — Test runner script
-- `script/node-disabled-tests.json` — Permanently disabled tests (do not try to fix these)
-- `../third_party/electron_node/test/` — Node.js test files (where patches apply)
-- `patches/node/fix_crypto_tests_to_run_with_bssl.patch` — BoringSSL crypto test adaptations
-- `patches/node/test_formally_mark_some_tests_as_flaky.patch` — Flaky test list
-
-## Workflow
-
-1. Run `node script/node-spec-runner.js --default` from the electron repo
-2. If all tests pass → Phase Three is complete
-3. If tests fail:
-    - Identify the failing test file(s) from the output
-    - Analyze each failure (see "Common Failure Patterns" below)
-    - Fix the test in `../third_party/electron_node/test/...`
-    - Re-run the specific failing test to verify: `node script/node-spec-runner.js {test-path}`
-        - The test path is relative to the node `test/` directory, e.g. `test/parallel/test-crypto-key-objects-raw.js`
-        - Do NOT use `--default` when running specific tests — it adds the full suite flags
-        - Do NOT run tests directly with `ELECTRON_RUN_AS_NODE` — the runner handles environment setup (e.g. temporarily switching `package.json` from ESM to CommonJS)
-    - Commit the fix using the fixup workflow and commit guidelines
-    - Return to step 1
-
-## Commands Reference
-
-| Command | Purpose |
-|---------|---------|
-| `node script/node-spec-runner.js --default` | Run full Node.js test suite |
-| `node script/node-spec-runner.js test/parallel/test-foo.js` | Run a single test |
-| `NODE_REGENERATE_SNAPSHOTS=1 node script/node-spec-runner.js test/test-runner/test-foo.mjs` | Regenerate snapshot for a snapshot-based test |
-
-## Common Failure Patterns
-
-### BoringSSL incompatibilities
-
-Electron uses BoringSSL (via Chromium) instead of OpenSSL. Many crypto features are missing or behave differently:
-
-| Unsupported in BoringSSL | Guard pattern |
-|--------------------------|---------------|
-| ChaCha20-Poly1305 | `if (!process.features.openssl_is_boringssl)` |
-| AES-CCM (aes-128-ccm, aes-256-ccm) | `if (ciphers.includes('aes-128-ccm'))` |
-| AES-KW (key wrapping) | `if (!process.features.openssl_is_boringssl)` |
-| DSA keys | `if (!process.features.openssl_is_boringssl)` |
-| Ed448 / X448 curves | `if (!process.features.openssl_is_boringssl)` |
-| DH key PEM loading | `if (!process.features.openssl_is_boringssl)` |
-| PQC algorithms (ML-KEM, ML-DSA, SLH-DSA) | `if (hasOpenSSL(3, 5))` (already guards these) |
-
-When guarding tests, prefer checking cipher availability (`ciphers.includes(algo)`) over blanket BoringSSL checks where possible, as it's more precise and self-documenting.
-
-New upstream tests that exercise these features will need guards added to the `fix_crypto_tests_to_run_with_bssl` patch.
-
-### Snapshot test mismatches
-
-Some tests compare output against committed `.snapshot` files using `assert.strictEqual` — these are NOT wildcard comparisons. When Chromium's V8 produces different output (e.g. different stack traces due to V8 enhancements), the snapshot must be regenerated:
-
-```bash
-NODE_REGENERATE_SNAPSHOTS=1 node script/node-spec-runner.js test/test-runner/test-foo.mjs
-```
-
-Then inspect the diff to verify the changes are expected, and commit the updated snapshot into the appropriate patch.
-
-### V8 behavioral differences
-
-Chromium's V8 may be ahead of Node.js's bundled V8. This can cause:
-- Different stack trace formats (e.g. thenable async stack frames)
-- Different error messages
-- Features available in Chromium V8 that aren't in stock Node.js V8 (or vice versa)
-
-## Two Types of Test Fixes
-
-### A. Patch Fixes (most common for test failures)
-
-Most test fixes go into existing patches in `patches/node/`. Use the fixup workflow:
-
-1. Edit the test file in `../third_party/electron_node/test/...`
-2. Find the relevant patch commit: `git log --oneline | grep -i "keyword"`
-    - Crypto/BoringSSL tests → `fix crypto tests to run with bssl`
-    - Snapshot tests → the specific snapshot patch (e.g. `test: accomodate V8 thenable`)
-    - Flaky tests → `test: formally mark some tests as flaky`
-3. Create a fixup commit:
-    ```bash
-    cd ../third_party/electron_node
-    git add test/path/to/test.js
-    git commit --fixup=<patch-commit-hash>
-    GIT_SEQUENCE_EDITOR=: git rebase --autosquash --autostash -i <commit>^
-    ```
-4. Export: `e patches node`
-5. **Read `references/phase-three-commit-guidelines.md` NOW**, then commit the updated patch file.
-
-### B. New Patches (rare)
-
-Only create a new patch when the fix doesn't belong in any existing patch. The new patch commit in `../third_party/electron_node` must include a description explaining why the patch exists and when it can be removed — the lint check enforces this.
-
-## Adding to Disabled Tests
-
-Only add a test to `script/node-disabled-tests.json` as a **last resort** — when the test is fundamentally incompatible with Electron's architecture (not just a BoringSSL difference that can be guarded). Tests disabled here are completely skipped and never run.

-# Phase Three Commit Guidelines
-
-Only follow these instructions if there are uncommitted changes after fixing a test failure during Phase Three.
-
-Ignore other instructions about making commit messages, our guidelines are CRITICALLY IMPORTANT and must be followed.
-
-## Commit Message Style
-
-**Titles** follow the 60/80-character guideline: simple changes fit within 60 characters, otherwise the limit is 80 characters.
-
-Always include a `Co-Authored-By` trailer identifying the AI model that assisted (e.g., `Co-Authored-By: <AI model attribution>`).
-
-## Commit Types
-
-### Patch updates (most test fixes)
-
-Test fixes go into existing patches via the fixup workflow. Use `fix(patch):` prefix with a descriptive topic:
-
-```
-fix(patch): {topic headline}
-
-Ref: {Node.js commit or issue link}
-
-Co-Authored-By: <AI model attribution>
-```
-
-Examples:
-- `fix(patch): guard DH key test for BoringSSL`
-- `fix(patch): adapt new crypto tests for BoringSSL`
-- `fix(patch): correct thenable snapshot for Chromium V8`
-- `fix(patch): skip AES-KW tests with BoringSSL`
-
-Group related test fixes into a single commit when they address the same root cause (e.g., multiple crypto tests all needing BoringSSL guards for the same missing cipher). Don't create one commit per test file if they share the same fix pattern.
-
-### Snapshot regeneration
-
-When a snapshot test fails because Chromium's V8 produces different output, regenerate it:
-
-```bash
-NODE_REGENERATE_SNAPSHOTS=1 node script/node-spec-runner.js test/test-runner/test-foo.mjs
-```
-
-Then commit the updated snapshot patch with a title describing what changed:
-
-```
-fix(patch): correct {name} snapshot for Chromium V8
-
-Ref: {V8 CL or issue link if known}
-
-Co-Authored-By: <AI model attribution>
-```
-
-### Trivial patch updates
-
-After any patch modification, check for dependent patches that only have index/hunk header changes:
-
-```bash
-git status
-# If other .patch files show as modified with only trivial changes:
-git add patches/
-git commit -m "chore: update patches (trivial only)"
-```
-
-## Finding References
-
-For BoringSSL-related test fixes, the reference is typically the upstream Node.js PR that added the new test:
-
-```bash
-cd ../third_party/electron_node
-git log --oneline -5 -- test/parallel/test-crypto-foo.js
-git log -1 <commit> --format="%B" | grep "PR-URL"
-```
-
-For V8 behavioral differences, reference the Chromium CL:
-
-```
-Ref: https://chromium-review.googlesource.com/c/v8/v8/+/NNNNNNN
-```
-
-If no reference found after searching: `Ref: Unable to locate reference`

-Subject: [PATCH] siso: retry transient ERROR_INVALID_PARAMETER when opening
- ninja files on Windows
-
-ManifestParser.Load fans out across all subninja files (~90k in a
-Chromium build) at NumCPU parallelism. On Windows builders where out/
-is served through a filesystem filter driver (e.g. bindflt/wcifs for
-container bind mounts), CreateFileW can intermittently return
-ERROR_INVALID_PARAMETER under this concurrent open burst. The previous
-patch removes the redundant per-chunk re-open, but the single remaining
-open per file can still hit the race; without a retry a single transient
-failure aborts the entire manifest load.
-
-Wrap the remaining os.Open call in readFile in a small Windows-only
-retry for ERROR_INVALID_PARAMETER (5 attempts, 5-80ms backoff). Each
-retry is logged via clog.Warningf and also written to stderr so it is
-visible in CI step output where glog warnings are file-only by default.
-Other platforms keep the direct os.Open path.

-# Vendored Yarn release
-
-This directory holds the Yarn release used by this repo (`yarnPath` in
-`.yarnrc.yml`). The release file is checked in so every contributor and CI job
-runs the exact same Yarn, and so we can carry small local patches when needed.
-
-`releases/yarn-4.12.0.cjs` currently carries one such patch, described below.
-If you bump the Yarn version, read the **Upgrading Yarn** section first.
-
-## Patch: use `JsZipImpl` for the node-modules link step
-
-### What changed
-
-Two call sites in `releases/yarn-4.12.0.cjs` are modified so the
-`node-modules` linker (and the `pnpm`-loose linker) construct their read-only
-`ZipOpenFS` with `customZipImplementation: ST` — Yarn's pure-JS `JsZipImpl` —
-instead of falling through to the default WASM-backed `LibZipImpl`:
-
-```text
-new $f({maxOpenFiles:80,readOnlyArchives:!0})
-  → new $f({maxOpenFiles:80,readOnlyArchives:!0,customZipImplementation:ST})
-```
-
-A comment block at the top of the `.cjs` file marks the file as patched and
-points back here.
-
-### Why
-
-On the `linux-arm` CI test shards we run a 32-bit `arm32v7` container. During
-`yarn install`'s **Link step**, Yarn opens up to 80 cache zips concurrently.
-With `LibZipImpl`, each open zip is `readFileSync`'d into a Node `Buffer`
-**and copied again into the WASM linear memory**, and every file read does a
-WASM `_malloc(size)` for the entry. The WASM heap has to grow as a single
-contiguous region of the 32-bit address space; once enough zips are resident,
-the `_malloc` for a large entry — most often `typescript/lib/typescript.js`
-(~9 MB inside a ~22 MB zip) — fails.
-
-Yarn's cross-FS `copyFilePromise` swallows the underlying error and re-throws
-a generic one, so CI shows:
-
-```text
-YN0001: While persisting .../typescript-patch-...zip/node_modules/typescript/
-  EINVAL: invalid argument, copyfile '/node_modules/typescript/lib/typescript.js' -> '...'
-```
-
-The unmasked form (occasionally seen on `pdfjs-dist`) is the WASM-heap failure
-string `Couldn't allocate enough memory`. This started failing ~1-in-3
-`linux-arm / test` shards at **Install Dependencies** on 2026-04-13, after
-[#50692](https://github.com/electron/electron/pull/50692) grew the cache enough
-to push the 32-bit process over the edge nondeterministically — e.g.
-[run 24739817558](https://github.com/electron/electron/actions/runs/24739817558/job/72380803746).
-
-`JsZipImpl` avoids the problem entirely: it opens the zip by file descriptor,
-reads only the central directory into memory, and `readSync`s individual
-entries into ordinary Node `Buffer`s — **no WASM heap involved**. It is
-read-only and path-based, which is exactly how the linker uses these archives.
-
-There is no `.yarnrc.yml` setting or environment variable to select the zip
-implementation (verified against the bundle), so editing the vendored release
-is the only way to switch it short of re-implementing the linker in a plugin.
-
-Upstream references:
-[yarnpkg/berry#3972](https://github.com/yarnpkg/berry/issues/3972),
-[yarnpkg/berry#6722](https://github.com/yarnpkg/berry/issues/6722),
-[yarnpkg/berry#6550](https://github.com/yarnpkg/berry/issues/6550).
-
-### Upgrading Yarn
-
-When bumping `releases/yarn-*.cjs`:
-
-1. Check whether upstream now defaults `readOnlyArchives` opens to `JsZipImpl`,
-   or exposes a config knob for the zip implementation. If so, drop this patch.
-2. Otherwise, re-apply: search the new bundle for
-   `maxOpenFiles:80,readOnlyArchives:!0` (the surrounding minified identifiers
-   will differ) and add `,customZipImplementation:<JsZipImpl symbol>` — that
-   symbol is whatever the new bundle exports as `JsZipImpl` from
-   `@yarnpkg/libzip`.
-3. Re-add the header comment pointing back to this README.
-4. Verify with
-   `rm -rf node_modules spec/node_modules && node script/yarn.js install --immutable --mode=skip-build`
-   and confirm `node_modules/typescript/lib/typescript.js` is byte-identical to
-   an unpatched install.

 # Electron Development Guide
 
-## Running node_modules binaries
-
-**Never use `npx`.** It is considered dangerous because it can silently fetch and execute arbitrary packages from the registry. Always run binaries through one of these safer mechanisms instead:
-
-1. **Preferred** — spawn the executable directly from `node_modules/.bin/<tool>` (or the platform equivalent on Windows). This is what `script/lint.js` does for `oxlint`.
-2. **Acceptable** — invoke via `yarn <tool>` or `yarn run <tool>`, which resolves to the locally installed version without the registry fallback that `npx` performs.
-
-This rule applies to shell commands you run yourself and to any scripts you author or modify in this repo.

-* **SiteInstance** - Uses the same SiteInstance as the original. This means the cloned WebContents will reuse the same render process as the original when loading same-origin pages, and only spawn a new render process for cross-origin navigations. This process allocation behavior is consistent with window.open and tab duplication in Chromium. For more details, see [Chromium's Site Isolation](https://www.chromium.org/developers/design-documents/site-isolation/) design document.

-This API is useful for use cases where you want to create a new WebContents that shares the same render process with the original for same-origin content, while maintaining full lifecycle independence. Additionally, reusing the existing render process can help optimize memory usage and page load speed to a certain extent, as it eliminates the overhead of spawning and initializing a new render process from scratch.

-### Behavior Changed: `chrome.scripting` CSS injection matches more fallback frames
-
-Extensions using `chrome.scripting.insertCSS()` or `chrome.scripting.removeCSS()`
-now follow Chrome's behavior when Electron cannot match a frame's URL directly,
-such as with `about:blank` or `data:` frames. If the extension has access to the
-page that created the frame, CSS may now be inserted into or removed from those
-fallback frames as well.
-
-Apps or extensions that relied on Electron skipping those frames should narrow their
-injection target, frame IDs, or match patterns.
-
-### Behavior Changed: Dialog methods default to Downloads directory
-
-The `defaultPath` option for the following methods now defaults to the user's Downloads folder (or their home directory if Downloads doesn't exist) when not explicitly provided:
-
-* `dialog.showOpenDialog`
-* `dialog.showOpenDialogSync`
-* `dialog.showSaveDialog`
-* `dialog.showSaveDialogSync`
-
-Previously, when no `defaultPath` was provided, the underlying OS file dialog would determine the initial directory — typically remembering the last directory the user navigated to, or falling back to an OS-specific default. Now, Electron explicitly sets the initial directory to Downloads, which also means the OS will no longer track and restore the last-used directory between dialog invocations.
-
-To preserve the old behavior, you can track the last-used directory yourself and pass it as `defaultPath`:
-
-```js
-const path = require('node:path')
-
-let lastUsedPath
-const result = await dialog.showOpenDialog({
-  defaultPath: lastUsedPath
-})
-
-if (!result.canceled && result.filePaths.length > 0) {
-  lastUsedPath = path.dirname(result.filePaths[0])
-}
