📝 Walkthrough
Merge Risk: 🔵 Low · up to The issues are limited to a developer-run parity script. It can miss duplicate watcher events, and a focused run can fail spuriously once its files are used up. Product behavior is not affected, so owners can fix these in follow-up. Pre-merge checks |

- Around line 423-432: Update the `fs.watch` catch block in `start()` to
preserve the watcher lifecycle when opening the root watch fails: after emitting
the error, mark the watcher ready and emit `ready` before returning so consumers
can complete deferred cleanup.
Review comments at
@apps/desktop/src/renderer/components/chat/chatTranscriptPresentation.ts:
- Around line 272-284: Update the `carry` callback to return `null` whenever
`append.replacedIndexes` is non-empty, forcing the active turn to be recomputed
when an existing event is replaced. Preserve the current append-only logic for
updates without replacements.

send the matching stopWatching action for a watchWorkspace request and return
without tracking it.
- Around line 198-200: Change the navigation listener that calls release() from
did-start-navigation to did-navigate, so the ledger and runtime watches are
released only after a main-frame document commits.
Review comments at @scripts/perf/service/tree-watcher-parity.mts:

count each event rather than deduplicating events in sets, then compare counts
so duplicate notifications from either watcher are reported.
- Around line 95-97: Update the operation error catch around ops[name] so a
failed operation records a parity failure, such as incrementing mismatches, and
the script exits with a failure status instead of succeeding after logging the
error.

Fixes ADE-175
Problem
ADE-175 lists the perf items that stayed open after the web-client fixes branch. Measurement on a loaded dev app (several projects and chats open) found more: a long chat cost more script time per streamed event as it grew, the web client downloaded the full app stylesheet before sign-in, a project or tab switch re-rendered parked surfaces, and the brain polled thousands of paths on macOS and kept the watches of a page after that page went away.
Cause
index.csswas one stylesheet, so the sign-in gate of the web client loaded all of it.setProjectreplaced an equal project object.Change and boundary
gate.cssholds only what the gate needs. The app stylesheet loads together with the app root. Shared rules moved intostyles/foundation.cssand two partials.ProjectSurfaceand the top bar are memoized. Appearance state has its own store module.watchTreeuses one recursivefs.watchwith a snapshot diff on macOS. Other platforms keep chokidar unchanged.configReloadServicestill polls three files. The per-keystroke render cost ofAgentChatPaneis not changed. The iOS command redaction that ADE-175 names is already on main from Web client: transcript zoom gap, command redaction, plain scene, -84% boot payload #1561.Measured on a Mac Studio M4 Max (before to after):
docs/perf/macos-baseline.mdhas the full tables. I did not run the signed-in production bench of the web client, because it registers a new device on the account.Verification
/quality: two review tracks, 20 findings (0 Blocker, 0 High), 17 fixed, 3 rejected with a reason; the gate is empty. The fixes include: file watches come back after a reconnect,close()cannot leave a watch open, a moved root reports its removed tree,readyfires after a watch error./test: 13 new tests and 1 extended test; each one failed when the behavior was broken on purpose. Affected files: 1,288 desktop tests in 25 files and 223 CLI tests pass.typecheckpass.lint:cipasses with no newade-uiviolation.scripts/perf/service/tree-watcher-parity.mts: 60 steps, 0 mismatches between the native watcher and chokidar.windows-foundationincluded.did-navigaterelease, and the user agent mark of the dev window. Tests and typecheck cover them.Authored with Claude Opus 5.5 via Claude Code in ADE.

Note
Medium Risk
Touches chat transcript correctness (incremental collapse must match full passes), file-watch lifecycle across reload/reconnect, and macOS watcher behavior; well-covered by new tests but regressions could affect Files updates or long-chat UI.
Overview
This PR targets ADE-175 with a broad performance pass: chat streaming, web sign-in load, multi-project navigation, and file watching on macOS.
Chat streaming stops doing full transcript passes on every event. The live merge keeps indexes across merges; the row builder replays from collapse checkpoints when provider tool-call resends replace envelopes in place; display filtering, runtime/turn folds, and derived session maps reuse prior work on plain appends. The pane skips redundant
setSelectedSessionIdupdates and stabilizes handlers (e.g. compaction retry) so rows do not re-render per event.Desktop shell freezes router location/match for parked project and Work surfaces (
ProjectSurfaceRouterScope), memoizes surfaces and the top bar, and reuses unchanged project bindings. Appearance moves toappearanceStore(andpinKey) so the hosted sign-in path does not pull in fullappStore.File watches add a ledger on the RPC handler and in the runtime bridge: watches are released on connection dispose, navigation, renderer death, or window destroy, and restored after reconnect. On macOS, directory trees use new
watchTree(one recursive native watch + snapshot diff) instead of chokidar polling in the file watcher and automation services.Dev marks the app window user agent (
ADEDevShell) so Vite can serve an empty browser-mock snapshot module, cutting dev renderer heap. Documentation in the perf skill captures measurement notes and follow-ups.Reviewed by Cursor Bugbot for commit 1765ca5. Configure here.
