-name: electron-node-upgrade
-description: Guide for performing Node.js version upgrades in the Electron project. Use when working on the roller/node/main branch to fix patch conflicts during `e sync --3`. Covers the patch application workflow, conflict resolution, analyzing upstream Node.js changes, building, running the Node.js test suite, and proper commit formatting for patch fixes.
----
-
-# Electron Node.js Upgrade: Phase One
-
-## Summary
-
-Run `e sync --3` repeatedly, fixing patch conflicts as they arise, until it succeeds. Then export patches and commit changes atomically.
-
-## Success Criteria
-
-Phase One is complete when:
-- `e sync --3` exits with code 0 (no patch failures)
-- All changes are committed per the commit guidelines
-
-Do not stop until these criteria are met.
-
-**CRITICAL** Do not delete or skip patches unless 100% certain the patch is no longer needed. For major version upgrades, patches that shim deprecated V8 APIs or backport upstream changes are often deletable because the new Node.js version already incorporates them — but verify before removing. Complicated conflicts or hard to resolve issues should be presented to the user after you have exhausted all other options. Do not delete the patch just because you can't solve it.
-
-**CRITICAL** Never use `git am --skip` and then manually recreate a patch by making a new commit. This destroys the original patch's authorship, commit message, and position in the series. If `git am --continue` reports "No changes", investigate why — the changes were likely absorbed by a prior conflict resolution's 3-way merge. Present this situation to the user rather than skipping and recreating.
-
-## Context
-
-The `roller/node/main` branch is created by automation to update Electron's Node.js dependency version in `DEPS`. No work has been done to handle breaking changes between the old and new versions.
-
-There are two types of Node.js version updates:
-- **Bumps** (patch/minor): Automated by `electron-roller[bot]` with commit title `chore: bump node to v{version}`. Trivial patch index updates are handled automatically by `patchup[bot]`. These often land cleanly, but may require manual patch fixes.
-- **Major upgrades** (e.g., v22 → v24): Manual, large PRs with commit title `chore: upgrade Node.js to v{X}.{Y}.{Z}`. These typically involve deleting obsolete patches, adapting many others, and updating `@types/node` in `package.json`.
-
-**Key directories:**
-- Current directory: Electron repo (always run `e` commands here)
-- `../third_party/electron_node`: Node.js repo (where patches apply)
-- `patches/node/`: Patch files for Node.js
-- `docs/development/patches.md`: Patch system documentation
-
-## Pre-flight Checks
-
-Run these once at the start of each upgrade session:
-
-1. **Clear rerere cache** (if enabled): `git rerere clear` in both the electron and `../third_party/electron_node` repos. Stale recorded resolutions from a prior attempt can silently apply wrong merges.
-2. **Ensure pre-commit hooks are installed**: Check that `.git/hooks/pre-commit` exists. If not, run `yarn husky` to install it. The hook runs `lint-staged` which handles clang-format for C++ files.
-
-## Workflow
-
-1. Run `e sync --3` (the `--3` flag enables 3-way merge, always required)
-2. If succeeds → skip to step 5
-3. If patch fails:
-   - Identify target repo and patch from error output
-   - Analyze failure (see references/patch-analysis.md)
-   - Fix conflict in `../third_party/electron_node` working directory
-   - Run `git am --continue` in `../third_party/electron_node`
-   - Repeat until all patches for that repo apply
-   - IMPORTANT: Once `git am --continue` succeeds you MUST run `e patches node` to export fixes
-   - Return to step 1
-4. When `e sync --3` succeeds, run `e patches all`
-5. **Read `references/phase-one-commit-guidelines.md` NOW**, then commit changes following those instructions exactly.
-
-## Commands Reference
-
-| Command | Purpose |
-|---------|---------|
-| `e sync --3` | Clone deps and apply patches with 3-way merge |
-| `git am --continue` | Continue after resolving conflict (run in node repo) |
-| `e patches node` | Export commits from node repo to patch files |
-| `e patches all` | Export all patches from all targets |
-| `e patches node --commit-updates` | Export patches and auto-commit trivial changes |
-| `e patches --list-targets` | List targets and config paths |
-
-## Patch System Mental Model
-
-```
-patches/node/*.patch  →  [e sync --3]  →  ../third_party/electron_node commits
-                      ←  [e patches]   ←
-```
-
-## When to Edit Patches
-
-| Situation | Action |
-|-----------|--------|
-| During active `git am` conflict | Fix in node repo, then `git am --continue` |
-| Modifying patch outside conflict | Edit `.patch` file directly |
-| Creating new patch (rare, avoid) | Commit in node repo, then `e patches node` |
-
-Fix existing patches 99% of the time rather than creating new ones.
-
-## Patch Fixing Rules
-
-1. **Preserve authorship**: Keep original author in TODO comments (from patch `From:` field)
-2. **Never change TODO assignees**: `TODO(name)` must retain original name
-3. **Update descriptions**: If upstream changed APIs or macros, update patch commit message to reflect current state
-4. **Never skip-and-recreate a patch**: If `git am --continue` says "No changes — did you forget to use 'git add'?", do NOT run `git am --skip` and create a replacement commit. The patch's changes were already absorbed by a prior 3-way merge resolution. This means an earlier conflict resolution pulled in too many changes. Present the situation to the user for guidance — the correct fix may require re-doing an earlier resolution more carefully to keep each patch's changes separate.

-# Electron Node.js Upgrade: Phase Two
-
-## Summary
-
-Run `e build -k 999 -- --quiet` repeatedly, fixing build issues as they arise, until it succeeds. Then run `e start --version` to validate Electron launches and commit changes atomically.
-
-Run Phase Two immediately after Phase One is complete.
-
-## Success Criteria
-
-Phase Two is complete when:
-- `e build -k 999 -- --quiet` exits with code 0 (no build failures)
-- `e start --version` has been run to check Electron launches
-- All changes are committed per the commit guidelines
-
-Do not stop until these criteria are met. Do not delete code or features, never comment out code in order to take short cut. Make all existing code, logic and intention work.
-
-## Context
-
-The `roller/node/main` branch is created by automation to update Electron's Node.js dependency version in `DEPS`. No work has been done to handle breaking changes between the old and new versions. Node.js APIs (especially internal V8 integration, OpenSSL/BoringSSL compatibility, and build system files) frequently change between versions. In every case the code in Electron must be updated to account for the change in Node.js, strongly avoid making changes to the code in Node.js to fix Electron's build.
-
-**Key directories:**
-- Current directory: Electron repo (always run `e` commands here)
-- `../third_party/electron_node`: Node.js repo (do not touch this code to fix build issues, just read it to obtain context)
-
-## Workflow
-
-1. Run `e build -k 999 -- --quiet` (the `--quiet` flag suppresses per-target status lines, showing only errors and the final result)
-2. If succeeds → skip to step 6
-3. If build fails:
-    - Identify underlying file in "electron" from the compilation error message
-    - Analyze failure
-    - Fix build issue by adapting Electron's code for the change in Node.js
-    - Run `e build -t {target_that_failed}.o` to build just the failed target we were specifically fixing
-        - You can identify the target_that_failed from the failure line in the build log. E.g. `FAILED: 2e506007-8d5d-4f38-bdd1-b5cd77999a77 "./obj/electron/shell/browser/api/electron_api_utility_process.o" CXX obj/electron/shell/browser/api/electron_api_utility_process.o` the target name is `obj/electron/shell/browser/api/electron_api_utility_process.o`
-    - **Read `references/phase-two-commit-guidelines.md` NOW**, then commit changes following those instructions exactly.
-    - Return to step 1
-4. **CRITICAL**: After ANY commit (especially patch commits), immediately run `git status` in the electron repo
-    - Look for other modified `.patch` files that only have index/hunk header changes
-    - These are dependent patches affected by your fix
-    - Commit them immediately with: `git commit -am "chore: update patches (trivial only)"`
-5. Return to step 1
-6. When `e build` succeeds, run `e start --version`
-7. Check if you have any pending changes in the Node.js repo by running `git status` in `../third_party/electron_node`
-    - If you have changes follow the instructions below in "A. Patch Fixes" to correctly commit those modifications into the appropriate patch file
-
-## Commands Reference
-
-| Command | Purpose |
-|---------|---------|
-| `e build -k 999 -- --quiet` | Build Electron, continue on errors, suppress status lines |
-| `e build -t {target}.o` | Build just one specific target to verify a fix |
-| `e start --version` | Validate Electron launches after successful build |
-
-## Two Types of Build Fixes
-
-### A. Patch Fixes (for files in patched Node.js files)
-
-When the error is in a file that Electron patches (check with `grep -l "filename" patches/node/*.patch`):
-
-1. Edit the file in the Node.js source tree (`../third_party/electron_node/...`)
-2. Create a fixup commit targeting the original patch commit:
-    ```bash
-    cd ../third_party/electron_node
-    git add <modified-file>
-    git commit --fixup=<original-patch-commit-hash>
-    GIT_SEQUENCE_EDITOR=: git rebase --autosquash --autostash -i <commit>^
-    ```
-3. Export the updated patch: `e patches node`
-4. Commit the updated patch file following `references/phase-one-commit-guidelines.md`.
-
-To find the original patch commit to fixup: `git log --oneline | grep -i "keyword from patch name"`
-
-The base commit for rebase is the Node.js commit before patches were applied. Find it by checking the `refs/patches/upstream-head` ref.
-
-### B. Electron Code Fixes (for files in shell/, electron/, etc.)
-
-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.
-
-# Critical: Read Before Committing
-
-- Before ANY Phase One commits: Read `references/phase-one-commit-guidelines.md`
-- Before ANY Phase Two commits: Read `references/phase-two-commit-guidelines.md`
-- Before ANY Phase Three commits: Read `references/phase-three-commit-guidelines.md`
-
-# High-Churn Patches
-
-These patches consistently require the most work during Node.js upgrades:
-
-- **`fix_handle_boringssl_and_openssl_incompatibilities.patch`** — Electron uses BoringSSL (via Chromium) while Node.js expects OpenSSL. This patch is large and complex, and upstream OpenSSL API changes frequently break it.
-- **`fix_crypto_tests_to_run_with_bssl.patch`** — Companion to the above; adapts Node.js crypto tests for BoringSSL. Can grow significantly during major upgrades.
-- **`support_v8_sandboxed_pointers.patch`** — V8 sandbox pointer support requires careful adaptation when V8 APIs change.
-- **`build_add_gn_build_files.patch`** — The GN build file patch is large and touches many build targets. Upstream build system changes frequently conflict.
-
-# Major Version Upgrades
-
-Major Node.js version transitions (e.g., v22 → v24) are significantly more involved than patch bumps:
-
-1. **Expect patch deletions.** Electron uses Chromium's V8, which is often ahead of the V8 version bundled in Node.js. Many patches exist to bridge this gap — shimming newer V8 APIs that Chromium's V8 has but Node.js' older V8 doesn't. When Node.js bumps to a newer major version, its V8 catches up to Chromium's, and those bridge patches can be deleted. In the v22 → v24 upgrade, 17 patches were deleted for this reason.
-2. **Update `@types/node`** in `package.json` to match the new major version.
-3. **Post-upgrade regressions are expected.** Even after the upgrade lands, follow-up fix PRs for edge cases (ESM path handling, certificate loading, platform-specific issues) are normal.

-# Analyzing Patch Failures
-
-## Investigation Steps
-
-1. **Read the patch file** at `patches/node/{patch_name}.patch`
-
-2. **Examine current state** of the file in the Node.js repo at mentioned line numbers
-
-3. **Check recent upstream changes:**
-   ```bash
-   cd ../third_party/electron_node
-   git log --oneline -10 -- {file}
-   ```
-
-4. **Find Node.js PR** in commit messages:
-   ```
-   PR-URL: https://github.com/nodejs/node/pull/{PR_NUMBER}
-   ```
-
-## Critical: Resolve by Intent, Not by Mechanical Merge
-
-When resolving a patch conflict, do NOT blindly preserve the patch's old code. Instead:
-
-1. **Understand the upstream commit's full scope** — not just the conflicting hunk.
-   Run `git show <commit> --stat` and read diffs for all affected files.
-   Upstream may have removed structs, members, or methods that the patch
-   references in other hunks or files.
-
-2. **Re-read the patch commit message** to understand its *intent* — what
-   behavior does it need to preserve or add?
-
-3. **Implement the intent against the new upstream code.** If the patch's
-   purpose is "add BoringSSL compatibility", add only the compatibility
-   layer — don't also restore old code that upstream separately removed.
-
-### Lesson: Upstream Removals Break Patch References
-
-- **Trigger:** Patch conflict involves an upstream refactor (not just context drift)
-- **Strategy:** After identifying the upstream commit, check its full diff for
-  removed types, members, and methods. If the patch's old code references
-  something removed, the resolution must use the new upstream mechanism.
-
-### Lesson: Separate Patch Purpose from Patch Implementation
-
-- **Trigger:** Conflict between "upstream simplified code" vs "patch has older code"
-- **Strategy:** Identify the *minimal* change the patch needs. If the patch
-  wraps code in a conditional, only add the conditional — don't restore old
-  code that was inside the conditional but was separately cleaned up upstream.
-
-### Lesson: Finish the Adaptation at Conflict Time
-
-- **Trigger:** A patch conflict involves an upstream API removal or replacement
-- **Strategy:** When resolving the conflict, fully adapt the patch to use the
-  new API in the same commit. Don't remove the old code and leave behind stale
-  references that will "be fixed in Phase Two." Each patch fix commit should be
-  a complete resolution.
-
-## Common Failure Patterns
-
-| Pattern | Cause | Solution |
-|---------|-------|----------|
-| Context lines don't match | Surrounding code changed | Update context in patch |
-| File not found | File renamed/moved | Update patch target path |
-| Function not found | Refactored upstream | Find new function name |
-| OpenSSL → BoringSSL mismatch | Crypto API change | Update to BoringSSL-compatible API |
-| GYP/GN build change | Build system refactor | Adapt build patch to new structure |
-| Deleted code | Feature removed | Verify patch still needed |
-| V8 API bridge patch conflicts | Node.js caught up to Chromium's V8 | Patch may be deletable — verify the API is now in Node.js' V8 natively |
-
-## Using Git Blame
-
-To find the commit that changed specific lines:
-
-```bash
-cd ../third_party/electron_node
-git blame -L {start},{end} -- {file}
-git log -1 {commit_sha}  # Look for PR-URL: line
-```
-
-## Verifying Patch Necessity
-
-Before deleting a patch, verify:
-1. The patched functionality was intentionally removed upstream
-2. Electron doesn't need the patch for other reasons
-3. No other code depends on the patched behavior
-
-**V8 bridge patches:** Electron uses Chromium's V8, which is often ahead of the V8 bundled in Node.js. Many patches exist to bridge this version gap — adapting Node.js code to work with newer V8 APIs that Chromium's V8 exposes. During major Node.js upgrades, Node.js' V8 catches up to Chromium's, and these bridge patches often become unnecessary. Check whether the API the patch shims is now available natively in the new Node.js version's V8.
-
-When in doubt, keep the patch and adapt it.
-
-## Phase Two: Build-Time Patch Issues
-
-Sometimes patches that applied successfully in Phase One cause build errors in Phase Two. This can happen when:
-
-1. **Incomplete types**: A patch disables a header include, but new upstream code uses the type
-2. **Missing members**: A patch modifies a class, but upstream added new code referencing the original
-
-### Finding Which Patch Affects a File
-
-```bash
-grep -l "filename.cc" patches/node/*.patch
-```
-
-### Matching Existing Patch Patterns
-
-When fixing build errors in patched files, examine the existing patch to understand its style:
-- Does it use `#if 0` / `#endif` guards?
-- Does it use `#if BUILDFLAG(...)` conditionals?
-- Does it use `#ifndef` / `#ifdef` guards for BoringSSL vs OpenSSL?
-- What's the pattern for disabled functionality?
-
-Apply fixes consistent with the existing patch style.

-# Phase One Commit Guidelines
-
-Only follow these instructions if there are uncommitted changes to `patches/` after Phase One succeeds.
-
-Ignore other instructions about making commit messages, our guidelines are CRITICALLY IMPORTANT and must be followed.
-
-## Each Commit Must Be Complete
-
-When resolving a patch conflict, fully adapt the patch to the new upstream code in the same commit. If the upstream change removes an API the patch uses, update the patch to use the replacement API now — don't leave stale references knowing they'll need fixing later. The goal is that each commit represents a finished resolution, not a partial one that defers known work to a future phase.
-
-## 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>`).
-
-### Patch conflict fixes
-
-Use `fix(patch):` prefix. The title should name the upstream change, not your response to it:
-
-```
-fix(patch): {topic headline}
-
-Ref: {Node.js commit or issue link}
-
-Co-Authored-By: <AI model attribution>
-```
-
-Only add a description body if it provides clarity beyond the title. For straightforward context drift or simple API renames, the title + Ref is sufficient.
-
-Examples:
-- `fix(patch): stop using v8::PropertyCallbackInfo<T>::This()`
-- `fix(patch): BoringSSL and OpenSSL incompatibilities`
-- `fix(patch): refactor module_wrap.cc FixedArray::Get params`
-
-### Upstreamed patch removal
-
-When patches are no longer needed (applied cleanly with "already applied" or confirmed upstreamed), group ALL removals into a single commit:
-
-```
-chore: remove upstreamed patch
-```
-
-or (if multiple):
-
-```
-chore: remove upstreamed patches
-```
-
-Most Node.js patches in Electron are Electron-authored (no upstream `PR-URL:`). If the patch originated from an upstream Node.js PR, no extra `Ref:` is needed. Otherwise, add a `Ref:` pointing to the relevant Node.js issue or commit if one exists.
-
-### Trivial patch updates
-
-After all fix commits, stage remaining trivial changes (index, line numbers, context only):
-
-```bash
-git add patches
-git commit -m "chore: update patches (trivial only)"
-```
-
-**Conflict resolution can produce trivial results.** A `git am` conflict doesn't always mean the patch content changed — context drift alone can cause a conflict. After resolving and exporting, inspect the patch diff: if only index hashes, line numbers, and context lines changed (not the patch's own `+`/`-` lines), it's trivial and belongs here, not in a `fix(patch):` commit.
-
-## Atomic Commits
-
-Each patch conflict fix gets its own commit with its own Ref.
-
-IMPORTANT: Try really hard to find the PR or commit reference per the instructions below. Each change you made should in theory have been in response to a change made in Node.js that you identified or can identify. Try for a while to identify and include the ref in the commit message. Do not give up easily.
-
-## Finding Commit/Issue References
-
-Use `git log` or `git blame` on Node.js source files in `../third_party/electron_node`. Look for:
-
-```
-PR-URL: https://github.com/nodejs/node/pull/XXXXX
-```
-
-or issue references in the patch itself:
-
-```
-Refs: https://github.com/nodejs/node/issues/XXXXX
-```
-
-Note: Most Node.js patches in Electron are Electron-authored and won't have upstream references. In that case, check `git log` in the Node.js repo to find which upstream commit caused the conflict.
-
-If no reference found after searching: `Ref: Unable to locate reference`
-
-## Example Commits
-
-### Patch conflict fix (simple — title is sufficient)
-
-```
-fix(patch): stop using v8::PropertyCallbackInfo<T>::This()
-
-Ref: https://github.com/nodejs/node/issues/60616
-
-Co-Authored-By: <AI model attribution>
-```
-
-### Patch conflict fix (complex — description adds value)
-
-```
-fix(patch): BoringSSL and OpenSSL incompatibilities
-
-Upstream updated OpenSSL APIs that diverge from BoringSSL. Adapted
-the compatibility shims in crypto patches to use the BoringSSL
-equivalents.

-# 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`

-# Phase Two Commit Guidelines
-
-Only follow these instructions if there are uncommitted changes in the Electron repo after any fixes are made during Phase Two that result a target that was failing, successfully building.
-
-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. Exception: upstream Node.js PR titles are used verbatim even if longer.
-
-Always include a `Co-Authored-By` trailer identifying the AI model that assisted (e.g., `Co-Authored-By: <AI model attribution>`).
-
-## Two Commit Types
-
-### For Electron Source Changes (shell/, electron/, etc.)
-
-When the upstream Node.js commit has a `PR-URL:`:
-
-```
-node#{PR-Number}: {upstream PR's original title}
-
-Ref: {Node.js PR link}
-
-Co-Authored-By: <AI model attribution>
-```
-
-When there is no `PR-URL:` but there is an issue reference or commit:
-
-```
-fix: {description of the adaptation}
-
-Ref: {Node.js issue or commit link}
-
-Co-Authored-By: <AI model attribution>
-```
-
-Use the **upstream commit's original title** when available — do not paraphrase or rewrite it. To find it: check the commit message in `../third_party/electron_node` for `PR-URL:` or `Refs:` lines.
-
-Only add a description body if it provides clarity beyond what the title already says (e.g., when Electron's adaptation is non-obvious). For simple renames, method additions, or straightforward API updates, the title + Ref link is sufficient.
-
-Each change should have its own commit and its own Ref. Logically group into commits that make sense rather than one giant commit. You may include multiple "Ref" links if required.
-
-IMPORTANT: Try really hard to find a reference. Each change you made should in theory have been in response to a change in Node.js. Check `git log` and `git blame` in the Node.js repo. Do not give up easily.
-
-### For Patch Updates (patches/node/*.patch)
-
-Use the same fixup workflow as Phase One and follow `references/phase-one-commit-guidelines.md` for the commit message format (`fix(patch):` prefix, topic style).
-
-## Dependent Patch Header Updates
-
-After any patch modification, check for other affected patches:
-
-```bash
-git status
-# If other .patch files show as modified with only index, line number, and context changes:
-git add patches/
-git commit -m "chore: update patches (trivial only)"
-```
-
-## Finding References
-
-Use `git log` or `git blame` on Node.js source files in `../third_party/electron_node`. Look for:
-
-```
-PR-URL: https://github.com/nodejs/node/pull/XXXXX
-Refs: https://github.com/nodejs/node/issues/XXXXX
-```
-
-Note: Many Node.js patches in Electron are Electron-authored and won't have upstream `PR-URL:` lines. Check the patch's own commit message for `Refs:` lines, or use `git log` in the Node.js repo to find which upstream commit caused the build break.
-
-If no reference found after searching: `Ref: Unable to locate reference`
-
-## Example Commits
-
-### Electron Source Fix (with upstream PR)
-
-```
-node#61898: src: stop using v8::PropertyCallbackInfo<T>::This()
-
-Ref: https://github.com/nodejs/node/pull/61898
-
-Co-Authored-By: <AI model attribution>
-```
-
-### Electron Source Fix (with issue reference, no PR)

-Date: Wed, 8 Apr 2026 23:24:15 -0700
-Subject: [PATCH] siso: reuse the outer *os.File for chunked ReadAt in
- fileParser.readFile
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The per-chunk goroutine currently re-opens fname to get its own handle
-for ReadAt. (*os.File).ReadAt is documented as safe for concurrent
-calls on the same File (on Windows it is ReadFile with an OVERLAPPED
-offset, so there is no shared seek state), so the extra open is
-redundant — the goroutines can share the outer f.
-
-Besides halving the CreateFileW calls per subninja, this avoids an
-intermittent 'The parameter is incorrect.' (ERROR_INVALID_PARAMETER)
-from bindflt.sys when out/ is a mapped directory inside a Windows
-container: bindflt's handle-relative NtCreateFile path races when a
-second relative open arrives while the first handle to the same target
-is still being set up. Absolute paths and single opens do not trigger
-it; see microsoft/Windows-Containers#<tbd>.

-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.

+### 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`

+
+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`:

+![Stabilization Branches](../images/versioning-sketch-1.png)
+
+Since Electron 8, stabilization branches are always **major** version lines, and named against the following template `$MAJOR-x-y` e.g. `8-x-y`.  Prior to that we used **minor** version lines and named them as `$MAJOR-$MINOR-x` e.g. `2-0-x`.
+
+We allow for multiple stabilization branches to exist simultaneously, one for each supported version. For more details on which versions are supported, see our [Electron Releases](./electron-timelines.md) doc.
+
+![Multiple Stability Branches](../images/versioning-sketch-2.png)
+
+Older lines will not be supported by the Electron project, but other groups can take ownership and backport stability and security fixes on their own. We discourage this, but recognize that it makes life easier for many app developers.
+
+## Beta releases and bug fixes
+
+Developers want to know which releases are _safe_ to use. Even seemingly innocent features can introduce regressions in complex applications. At the same time, locking to a fixed version is dangerous because you’re ignoring security patches and bug fixes that may have come out since your version. Our goal is to allow the following standard semver ranges in `package.json` :
+
+* Use `~2.0.0` to admit only stability or security related fixes to your `2.0.0` release.
+* Use `^2.0.0` to admit non-breaking _reasonably stable_ feature work as well as security and bug fixes.
+
+What’s important about the second point is that apps using `^` should still be able to expect a reasonable level of stability. To accomplish this, SemVer allows for a _pre-release identifier_ to indicate a particular version is not yet _safe_ or _stable_.
+
+Whatever you choose, you will periodically have to bump the version in your `package.json` as breaking changes are a fact of Chromium life.
+
+The process is as follows:
+
+1. All new major and minor releases lines begin with a beta series indicated by SemVer prerelease tags of `beta.N`, e.g. `2.0.0-beta.1`. After the first beta, subsequent beta releases must meet all of the following conditions:
+    1. The change is backwards API-compatible (deprecations are allowed)
+    2. The risk to meeting our stability timeline must be low.
+2. If allowed changes need to be made once a release is beta, they are applied and the prerelease tag is incremented, e.g. `2.0.0-beta.2`.
+3. If a particular beta release is _generally regarded_ as stable, it will be re-released as a stable build, changing only the version information. e.g. `2.0.0`. After the first stable, all changes must be backwards-compatible bug or security fixes.
+4. If future bug fixes or security patches need to be made once a release is stable, they are applied and the _patch_ version is incremented
+e.g. `2.0.1`.
+
+Specifically, the above means:
+
+1. Admitting non-breaking-API changes before Week 3 in the beta cycle is okay, even if those changes have the potential to cause moderate side-effects.
+2. Admitting feature-flagged changes, that do not otherwise alter existing code paths, at most points in the beta cycle is okay. Users can explicitly enable those flags in their apps.
+3. Admitting features of any sort after Week 3 in the beta cycle is 👎 without a very good reason.
+
+For each major and minor bump, you should expect to see something like the following:
+
+```plaintext
+2.0.0-beta.1
+2.0.0-beta.2
+2.0.0-beta.3
+2.0.0
+2.0.1
+2.0.2
 ```
 
-Since Electron 8, stabilization branches are always **major** version lines, and named against the following template `$MAJOR-x-y` e.g. `8-x-y`. (Prior to that, we used **minor** version lines and named them as `$MAJOR-$MINOR-x` e.g. `2-0-x`.)

-
-A bug fix comes into `main` that can be backported to the release branch. The patch is applied,
-and it is published in the next `v42.0.0-alpha.2` release.
