ApprovabilityVerdict: Needs Human Approval Macroscope's review found this PR requires human approval — This PR enables React Compiler transformation by default for production mobile bundles and adapts existing navigation and snooze behavior to that transformation. It also adds a mobile lint configuration override that permits manual memo hooks, so the default-build and static-analysis changes require human review. You can add or adjust custom eligibility rules. Learn more. |

Review comments at @apps/mobile/package.json:
- Line 149: Remove the direct babel-plugin-react-compiler dependency from the
mobile package manifest because babel-preset-expo already provides it; only
retain a direct pin if required, and then add a scoped Knip exception for it.
Review comments at @oxlint-plugin-t3code/rules/no-memo-directives.ts:
- Line 16: Update the directive guard in the rule to exclude both null and
undefined before calling MEMO_DIRECTIVES.has, so only a string reaches the Set
lookup. Use a null check consistent with the repository’s lint rules.

… typing babel-preset-expo already depends on and loads babel-plugin-react-compiler, so knip flagged the direct pin as unused. node.directive is string | null. Co-Authored-By: Claude Opus 5.5 <[email protected]>
A second rule duplicated no-manual-memo's directive check. no-manual-memo now takes allowMemoHooks for codebases still ratcheting toward full compiler coverage, and rejects "use no memo" and "use no forget" too. Co-Authored-By: Claude Opus 5.5 <[email protected]>

…mpiler React Navigation calls layout and screenLayout as plain functions during its own render. With the compiler on, a component passed there allocates its memo cache inside the navigator's hooks, which crashed Android at launch with useMemoCache size mismatches.

…der the React Compiler The row read the clock during render to decide whether a queued turn start still blocks snoozing. The compiler caches that result on `thread`, so after the gate's expiry the timer bumped a tick, the row re-rendered with the same frozen time, saw the gate still open and re-armed with a 50ms delay, forever. The gate's clock is now state set by the timer, and a gate that is still closed past its expiry no longer arms a timer. Co-Authored-By: Claude Opus 5.5 <[email protected]>

…ingdotgg#20967) Co-authored-by: Claude Opus 5.5 <[email protected]> Fork adaptation: The lockfile is regenerated from the fork's dependency graph; unlike upstream's, @babel/[email protected] is still resolved. The fork's mobile review diff hook passes generated paths to the parsed-diff cache through a local value, so the compiler can preserve its memoization and the file stays out of KNOWN_BAILOUTS.

Mobile did not run the React Compiler at all, so its ~1243 manual
useMemo/useCallback/memocalls were the only memoization. Unlike web, where oxc in our own Vite config runs the compiler, mobile goes through Metro andbabel-preset-expo. So this PR first proves the compiler really runs in that pipeline, then adds a ratchet that tracks which files it compiles.What changed
experiments.reactCompiler: trueinapps/mobile/app.config.ts. Expo CLI turns this intotransform.reactCompiler, Metro's transformer turns that into thesupportsReactCompilercaller flag, andbabel-preset-expothen addsbabel-plugin-react-compiler. Release bundles usepanicThreshold: "NONE", so a bailout is silent: the function ships unmemoized.babel-plugin-react-compilerand@babel/coreare now explicit mobile devDependencies, so the test resolves the same copies Metro does.apps/mobile/src/reactCompilerCoverage.test.ts:metro.config.js, runs its realbabelTransformerPath(@expo/metro-config's transformer) on a component, and checks thatreact/compiler-runtimeappears withreactCompiler: "true"and does not appear with"false".app.config.tssets the experiment..ts/.tsxfile underapps/mobile/srcwithbabel.config.js's presets, using Metro's iOS release caller flags. The only addition is a logger on the preset's ownreact-compileroption, which collectsCompileError/CompileSkipevents. The plugin options are therefore exactly the ones Metro uses.KNOWN_BAILOUTSlists every file that bails today, with its reason category. The test fails if a file outside the list bails, and also if a listed file now compiles, so the list can only shrink. It also fails if a listed file no longer exists. I checked both failure directions by hand: adding atry/finallyto a compiling screen fails it, and listing a file that compiles fails it.t3code/no-manual-memonow also rejects"use no memo"and"use no forget", and takes anallowMemoHooksoption. Mobile runs it withallowMemoHooks: true, so the directives are errors there (0 hits today) whileuseMemo/useCallbackstay legal (about 1243 hits). Dropping the option is the follow-up, onceKNOWN_BAILOUTSis empty.docs/internals/mobile-development.md: a short section explaining where the compiler is switched on (nothing inbabel.config.js), why bailouts are silent, and how the ratchet works.Coverage today
773 of 861 source files compile. 88 files are allowlisted (files can have more than one category):
trywithoutcatchtry/finallythrowinsidetrytryimport(),??=, etc.)By directory:

Each takes files off the list and drops their manual memos, ending at 84 allowlisted files.
Verifying a built bundle
I ran this on Linux. The production iOS bundle has 585
memo_cache_sentineloccurrences with the experiment on, and 2 with it off (those 2 come from a prebuilt dependency). Grep formemo_cache_sentinel, notreact/compiler-runtime: Metro rewrites import specifiers to numeric module ids, so the stringreact/compiler-runtimedoes not survive bundling (0 hits either way). In unbundled transform output, such as the test's Metro transformer check,react/compiler-runtimeis the right marker.Checks run

Measurement
Scenario
stream-replyfrom the render harness in #21001 at 8d41c049c5: an open thread streams a Claude Haiku 5.5 turn while the composer is idle, with a 12 s window mid-stream. Device: Android emulator, Pixel 9 API 36, on nucbox-1, with Metro and an isolated seeded server on cups. Basemain13aa882c22, then this branch at 7f7d6390d6. Median of 3.Runs (renders/commits): main 3163/41, 3163/39, 2047/31. This PR: 1243/33, 1726/40, 1249/33.
ThreadListV2RowrendersThe per-component output of the 7f7d639 run was not kept, so there is no component split for it. The table below comes from the earlier measurement on main in the same setup (
mainmedian 2019/31), before the fix:AnimatedComponent(ViewAnimatedComponent(View props:style,childrenIconButtonPressabilityDebugView parent-same-props<-ViewAppSymbolViewTextInputHostProvider props:childrenPressabilityDebugViewAppSymbolView parent-same-props<-ViewAppTextHostView props:style,childrenWhat it means: with the compiler on, a streaming thread does about half the rendering work per commit, and the median total fell 61%. Commit count also varies with provider pace. The thread shell files are still on
KNOWN_BAILOUTS, so most of the saving is in compiled leaf components under them.The 7x storm was not reproduced. Before the fix in 7f7d639, an earlier session measured this branch at 14695 renders in 179 commits (main: 2019/31). Nearly all of it was the home
ThreadListV2Rowand its swipe wrappers, rendering about 154 times per window with causeThreadListV2Row state#19, the snooze gate'suseStatetick. By the session that measured the fix, the seeded data had aged past the gate.
