bug: browser crash after an infinite loop stop

[kbuffardi]

Description

I programmed an infinite loop that produced a lot of output when I ran it. But I stopped it using the STOP button. However, when close the tab, the whole Chrome browser crashed with the provided error log. When I open the extension again with the project open, it crashes again (even if I don't re-run the program) when I try to close the extension's tab.

Expected behavior

After a STOP incident, the Terminal should be reset to its initial state with all input/output buffers cleared and any other side-effects of the program run cleared so they do not persist when the extension is re-opened.

Steps to reproduce

See the description.

Environment

MacOS 15.7.3
Chrome 153.0.8010.36
browser.cpp v0.4.8

Before submitting

• I searched existing issues and did not find a duplicate.
• I have provided enough information to reproduce the issue.

[kbuffardi]

Proposed implementation plan

1. Make STOP a hard terminal/run reset (src/ui/terminal.js). Add a focused reset path used only for an interrupted run. It will invalidate active stdin/run state, clear pending input and the xterm buffer using its API, then redraw the normal prompt. The terminal should not retain the runaway program's scrollback or an interrupted-process transcript.
2. Prevent output queued before STOP from reaching the terminal (src/ui/terminal.js, src/ui/toolbar.js, and/or src/ui/app.js). Associate the active run with a generation/token, invalidate it before terminating the worker, and ignore stdout, stderr, and run-result messages from a superseded worker/run. Compiler diagnostics must remain unaffected.
3. Harden the worker lifecycle and unload path (src/ui/app.js). Keep replacement-worker binding ordered so old worker messages cannot update UI, and explicitly terminate/reset any active run before session persistence on tab close. The persisted session must remain limited to workspace/tab state, never transient terminal output.
4. Add regression coverage. Extend scripts/e2e-terminal-stop.test.mjs for hard reset, stale-output suppression, and repeated STOP. Extend scripts/e2e-workspace-file-tracking.test.mjs for stale worker messages after replacement. Add a Chrome smoke scenario in scripts/smoke-browser.mjs using a burst-output fake worker to verify STOP leaves a clean terminal and close/reload does not consume stale output.
5. Consider a bounded run-output safeguard. If reproduction shows browser instability remains possible before STOP is processed, cap per-run terminal output and auto-stop with one concise warning. This is a secondary guard, not a substitute for correct STOP teardown.

Acceptance criteria

• Pressing STOP on an infinite-output run leaves the terminal in its clean prompt state with no prior run output, input, or active stdin buffers.
• Queued messages from the terminated worker cannot append output, update files, or restore the terminal after STOP.
• Closing and reopening an extension tab after STOP restores only the intended workspace/session state and does not replay run output.
• Existing normal completion, Ctrl+C, compile diagnostics, and worker-replacement behavior remain intact.

Verification

• npm run test:e2e
• npm run lint
• npm run build
• npm run test:browser:chrome when browser-test prerequisites are installed.

Open UX decision

Should STOP show a brief interruption notice before returning to the clean prompt, or be visually indistinguishable from a fresh terminal? The issue's expected behavior favors the latter.

[kbuffardi]

Revised implementation plan (reviewed)

Confirmed UX: stopping an active program—by the STOP button or active-run Ctrl+C—ends at exactly one normal prompt. It must display no ^C, no “Process interrupted.” message, no retained output, and no retained scrollback from the stopped run.

1. Define a dedicated hard-reset contract in src/ui/terminal.js

Add a focused helper for interrupted runs. Before drawing the prompt, it must clear xterm's actual screen/scrollback buffer and all associated local state: typed input, history cursor, running, preparingRun, stdin session/transport references, pending stdin chunks/flush state, runDone, and logical line tracking. Redraw only the canonical prompt, and only when initialPromptShown is true.

Update stopRun() to use this helper before invoking worker teardown. Remove the current newline/^C transcript and Process interrupted. output. Preserve idle Ctrl+C shell-line behavior; only an active-run Ctrl+C uses the hard-reset path.

2. Quarantine stopped-run worker messages

Add a run generation/token shared by the run initiator and message handler. Invalidate it before terminating and replacing the worker. Require run-start, stdout, stderr, and run-result handling to match the active generation, so queued messages from a stopped/superseded run are discarded.

Compiler diagnostics and normal compile results remain outside this run-output suppression unless their worker itself has been replaced.

3. Block all stale run-result side effects in src/ui/toolbar.js

Do the generation check before any terminal/UI or workspace mutation. A stale result must not change compiler status, restore a prompt, write vfsChanges, process vfsDeletes, refresh Explorer/tabs, invoke syncWorkspaceFromDisk('run-result'), emit persistence warnings, or schedule session persistence. STOP must also cancel pending compile-and-run continuation/preparation state.

4. Keep teardown synchronous at tab close

Do not depend on asynchronous cleanup inside beforeunload. Ensure normal STOP immediately invalidates transient state, detaches/replaces the worker, and leaves persistence with only workspace/tab data to save. The unload path may terminate a live worker defensively, but must not await work or append terminal output.

5. Add focused regression coverage

• Extend scripts/e2e-terminal-stop.test.mjs: STOP and active-run Ctrl+C leave exactly one clean prompt; no interruption text, prior output, typed input, or queued stdin state remains; repeated STOP stays idempotent; idle Ctrl+C retains existing shell behavior.
• Extend scripts/e2e-workspace-file-tracking.test.mjs: delayed stdout, stderr, run-start, and run-result after STOP cannot alter terminal/UI state or write runtime files.
• Extend scripts/smoke-browser.mjs: use a fake worker that produces burst output and delayed run messages, then STOP and close/reopen; assert no replayed output, stale writeback, or crash-prone retained terminal state.

Acceptance criteria

• After an infinite-output run is stopped, the terminal contains only its normal prompt.
• No queued output or stale lifecycle result from that run can reach the terminal or mutate workspace/session state.
• Normal completion, compiler diagnostics, compile-and-run behavior, and idle Ctrl+C remain intact.
• Session restore contains only supported workspace/tab state and never run output.

Verification

• npm run test:e2e
• npm run lint
• npm run build
• npm run test:browser:chrome when its prerequisites are available.

Reopening this because 0.4.9 implemented the pristine terminal but the crash is still happening.

confirmed reproduction matrix shows that a program never needs to run: opening
and then closing the extension is sufficient. The common application-controlled
path is the beforeunload listener added in v0.4.9, which explicitly calls
worker.terminate() on the Clang/WASM worker. The browser already owns worker
shutdown when its page unloads, so this plan removes that redundant shutdown
operation while retaining STOP's separate, live-run worker replacement behavior.

Evidence and decision

• Issue bug: browser crash after an infinite loop stop #92 reproduces after a clean Chrome restart in all four cases: no run,
  finite run, stopped infinite-output run after a delay, and immediate close
  after STOP.
• Therefore terminal content, output volume, run-result writeback, and session
  state are not required to trigger the crash.
• src/ui/app.js creates a compiler worker for every page load and v0.4.9 added
  explicit worker.terminate() inside beforeunload.
• The macOS crash is a native Chrome ThreadPoolForegroundWorker SIGTRAP, so
  the application must avoid the triggering lifecycle call rather than attempt
  to catch it in JavaScript.

Scope

In scope

• Remove the explicit compiler-worker termination from page unload.
• Preserve session persistence on unload.
• Preserve STOP's runtime behavior: terminate the active worker and create a
  replacement worker so a CPU-bound WASM run can be interrupted.
• Add regression coverage for the unload contract and a real-Chrome close smoke
  scenario where practical.

Out of scope

• Output throttling/backpressure, terminal queue changes, and run-generation
  protocol changes. The no-run reproduction proves they are not required for
  this defect.
• Changes to Chrome, macOS, or Clang/WASM assets.

Task 1: Separate page-unload from active-run teardown

Description: Update src/ui/app.js so beforeunload persists the session
but does not invoke terminate() on the compiler worker. Keep the existing
onStopRun behavior unchanged because it is the explicit user interrupt path.

Acceptance criteria:

• Closing an idle extension tab does not call Worker#terminate().
• Closing an extension tab still requests session persistence.
• Pressing STOP during an active run still terminates the old worker,
  creates a replacement, and rebinds the toolbar to that replacement.

Verification:

• Add a focused test that captures fake-worker terminate() calls across
  the unload and STOP paths.
• npm run test:e2e
• npm run lint
• npm run build

Dependencies: None.

Files likely touched:

• src/ui/app.js
• A new focused application-lifecycle test under scripts/
• package.json only if the new test must be registered with test:e2e

Estimated scope: Small (2–3 files).

Task 2: Verify the real browser close path

Description: Extend the Chrome smoke workflow to load browser.cpp with its
fake compiler worker, wait for initialization, and close the page without
running a program. This validates the exact minimal reproduction without
requiring a Clang execution.

Acceptance criteria:

• The smoke scenario covers open → compiler worker initialization → close,
  with no Run or STOP action.
• The scenario completes without a browser crash and does not leave a
  browser process failure in the smoke runner.
• Existing STOP/run smoke behavior remains covered.

Verification:

• npm run test:browser:chrome when the local Chrome prerequisites are
  installed.

Dependencies: Task 1.

Files likely touched:

• scripts/smoke-browser.mjs

Estimated scope: Small (1 file).

Checkpoint: before review

• Focused unload and STOP lifecycle tests pass.
• Full Node E2E suite, lint, and production build pass.
• Chrome smoke test passes on macOS/Chrome, or any environment limitation
  is recorded in the pull request.
• Manual confirmation on the reported Chrome profile: close an idle
  browser.cpp tab repeatedly after a full Chrome restart.

Risks and mitigations

Risk	Impact	Mitigation
Session persistence relied incidentally on the termination call	Medium	Test persistence invocation independently of worker teardown.
STOP behavior regresses while separating the two paths	Medium	Assert explicit terminate-and-replace behavior in the focused lifecycle test.
Chrome crash remains after removing explicit termination	High	Report the minimal no-run reproduction and uploaded crash ID 6001a887f0400000 to Chromium; investigate extension/page-close interactions only after this regression is ruled out.

Human review decision

Approve this narrow lifecycle fix before implementation. Do not fold the earlier
output-backpressure proposal into this change unless a post-fix reproduction
shows a separate high-volume-output defect.

Implementation Plan: Issue #92 — avoid compiler-worker teardown during tab unload

Overview

Mitigate the Chrome crash that occurs when closing the browser.cpp extension
tab. The confirmed reproduction matrix shows that a program never needs to run:
opening and then closing the extension is sufficient. The highest-value
application-controlled trigger is the beforeunload listener added in v0.4.9,
which explicitly calls worker.terminate() on the Clang/WASM worker. The
browser already owns dedicated-worker shutdown when its page unloads, so this
plan removes that redundant shutdown operation while retaining STOP's separate,
live-run worker replacement behavior. This is a targeted mitigation, not proof
that Chrome has no independent crash condition.

Evidence and decision

• Issue bug: browser crash after an infinite loop stop #92 reproduces after a clean Chrome restart in all four cases: no run,
  finite run, stopped infinite-output run after a delay, and immediate close
  after STOP.
• Therefore terminal content, output volume, and run-result writeback are not
  required to trigger the crash. Restored workspace/session state remains a
  variable because it is restored on page load.
• src/ui/app.js creates a compiler worker for every page load and v0.4.9 added
  explicit worker.terminate() inside beforeunload.
• The macOS crash is a native Chrome ThreadPoolForegroundWorker SIGTRAP, so
  JavaScript cannot catch it. Removing the unload-time termination is the
  highest-value app-controlled change to test first.
• The uploaded report identifies Chrome 153.0.8010.48 but lists a loaded
  Chrome Framework 153.0.8010.37; manual verification must control for a
  fully restarted, version-consistent Chrome installation and profile.

Scope

In scope

• Remove the explicit compiler-worker termination from page unload.
• Preserve session persistence on unload.
• Preserve STOP's runtime behavior: terminate the active worker and create a
  replacement worker so a CPU-bound WASM run can be interrupted.
• Add regression coverage for the unload contract and a real-Chrome close smoke
  scenario where practical.

Out of scope

• Output throttling/backpressure, terminal queue changes, and run-generation
  protocol changes. The no-run reproduction makes them inappropriate to bundle
  into this narrow mitigation; revisit them only if high-output STOP cases
  persist after this change.
• Changes to Chrome, macOS, or Clang/WASM assets.

Task 1: Separate page-unload from active-run teardown

Description: Update src/ui/app.js so beforeunload persists the session
but does not invoke terminate() on the compiler worker. Update the adjacent
comment to describe page-owned worker shutdown accurately. Keep the existing
onStopRun behavior unchanged because it is the explicit user interrupt path.

Acceptance criteria:

• Closing an idle extension tab does not call Worker#terminate().
• Closing an extension tab still requests session persistence.
• Pressing STOP during an active run still terminates the old worker,
  creates a replacement, and rebinds the toolbar to that replacement.

Verification:

• npm run test:e2e
• npm run lint
• npm run build

Dependencies: None.

Files likely touched:

• src/ui/app.js
• scripts/smoke-browser.mjs (Task 2)

Estimated scope: Small (1–2 files).

Task 2: Verify the real browser close path

Description: Extend the Chrome smoke workflow to load browser.cpp with its
fake compiler worker, wait for initialization, and close the page without
running a program. After close, wait briefly and prove that the controlled
Chrome process/automation connection remains usable before runner cleanup.
This validates the exact minimal reproduction without requiring a Clang
execution.

Acceptance criteria:

• The smoke scenario covers open → compiler worker initialization → close,
  with no Run or STOP action.
• After the extension page closes, the smoke runner waits a bounded
  post-close interval and successfully performs a browser-level operation (or
  otherwise verifies the controlled Chrome process is alive) before cleanup.
• Existing STOP/run smoke behavior remains covered.

Verification:

• npm run test:browser:chrome when the local Chrome prerequisites are
  installed.

Dependencies: Task 1.

Files likely touched:

• scripts/smoke-browser.mjs

Estimated scope: Small (1 file).

Checkpoint: before review

• Focused unload and STOP lifecycle tests pass.
• Full Node E2E suite, lint, and production build pass.
• Chrome smoke test passes on macOS/Chrome, or any environment limitation
  is recorded in the pull request.
• Manual preflight: fully quit Chrome; verify Chrome and Chrome Framework
  versions are consistent; then run the idle open-close case once in the
  reporter profile and once in a fresh profile where possible.
• Manual confirmation: repeatedly close an idle browser.cpp tab after the
  preflight restart, then separately repeat the delayed-STOP and immediate-STOP
  cases.
• If the idle-close crash persists, capture a new Crash Report ID and shift
  investigation to Chrome/framework/profile/extension-page teardown instead of
  expanding this PR into output backpressure work.

Risks and mitigations

Risk	Impact	Mitigation
Session persistence relied incidentally on the termination call	Medium	Test persistence invocation independently of worker teardown.
STOP behavior regresses while separating the two paths	Medium	Assert explicit terminate-and-replace behavior in the focused lifecycle test.
Chrome crash remains after removing explicit termination	High	Treat this mitigation as unsuccessful, capture a fresh Crash Report ID, and report the minimal no-run reproduction (including 6001a887f0400000) to Chromium before investigating other teardown variables.

Human review decision

Approved by the user after plan review: implement this narrow lifecycle
mitigation, keep STOP behavior unchanged, and rely on real-Chrome smoke/manual
verification rather than adding a helper solely to unit-test the deleted unload
call. Do not fold the earlier output-backpressure proposal into this change
unless a post-fix reproduction shows a separate high-volume-output defect.

Implementation Plan: Issue #92 — move directory-handle persistence out of tab unload

Overview

Fix the Chrome crash reported in issue #92 by preventing browser.cpp from
opening IndexedDB and storing a live FileSystemDirectoryHandle while the
extension page is unloading. Persist the handle when a folder is acquired or
reconnected, persist serializable workspace and tab state proactively during
normal interaction, and perform no asynchronous persistence from
beforeunload.

This plan supersedes the earlier output-backpressure and unload-worker plans.
No production implementation has started.

Decision record

@kbuffardi: "discard the previous plan and write a new plan that adopts this newly diagnosed fix"

Codex (GPT-5) replaced the prior plans with the IndexedDB/unload-persistence
plan below, based on the folder/no-folder and DevTools diagnostic results.

Evidence and diagnosis

Observed

• Closing the extension without opening a folder does not crash Chrome.
• Opening the original project and closing the tab crashes without rerunning
  its infinite-loop program.
• Opening a different empty folder and closing the tab also crashes.
• After opening an empty folder, replacing IDBFactory.prototype.open with a
  function that throws prevents the close-tab crash.
• The current beforeunload handler calls worker.terminate() and then
  persistenceGate.persist().
• persistSession() obtains the live directory handle and calls
  handleStore.save(dirHandle), which opens IndexedDB and stores that handle.

Conclusion and confidence

The DevTools experiment is a strong discriminator: it left the live directory
handle, worker termination, page teardown, and subsequent serializable-storage
path in place, but prevented the unload-time IndexedDB open/write. The
application-controlled trigger is therefore, with high confidence, the
IndexedDB operation that stores the directory handle during page teardown.

The native ThreadPoolForegroundWorker crash is ultimately a Chrome defect;
the application fix is to avoid initiating this unsafe browser path. The
experiment does not identify the faulty Chrome native component or prove that
all IndexedDB directory-handle writes are unsafe outside unload.

Architecture decisions

• Split directory-handle persistence from serializable session-state
  persistence. A normal tab/editor/workspace state save must never write or
  clear IndexedDB.
• Save the directory handle only at stable workspace lifecycle boundaries:
  successful folder open, folder reconnect, and save-to-folder acquisition.
• Clear the stored handle only during an explicit abandon/new-project flow.
• Save JSON-safe workspace, tab, and editor state proactively and with a short
  debounce during normal interaction so correctness does not depend on unload.
• beforeunload must start no IndexedDB or chrome.storage operation. Keep the
  existing synchronous worker.terminate() behavior unchanged: the successful
  diagnostic close still exercised it, so it is not the trigger isolated here.
• Preserve the existing IndexedDB database, object store, and key so previously
  saved sessions remain compatible.

Scope

In scope

• Refactor the session-persistence API into explicit handle, state, and clear
  operations.
• Update folder acquisition/reconnection paths to save the handle immediately.
• Persist current active-editor content and other serializable session state
  before unload through event-driven/debounced saves.
• Remove asynchronous persistence from beforeunload.
• Preserve live-handle restore, snapshot-only fallback, startup gating, and
  explicit session abandonment.
• Add focused persistence tests and real-Chrome/manual close verification.

Out of scope

• Terminal output backpressure, run generations, xterm queues, and compiler
  worker protocol changes.
• Changes to STOP or its terminate-and-replace behavior.
• Changes to Chrome, macOS, or the Clang/WASM toolchain.

Task 1: Classify and lock down persistence responsibilities

Description: Audit every current persistence caller and classify it as a
handle save, state-only save, full clear, or no persistence. Establish a clear
API contract in createSessionPersistence(); recommended operations are
persistWorkspaceSession(), persistSessionState(), and
clearPersistedSession().

Acceptance criteria:

• persistSessionState() writes only JSON-safe data to
  chrome.storage.local and never calls handleStore.save() or
  handleStore.clear().
• persistWorkspaceSession() stores the current directory handle and then
  persists the serializable state, even if handle storage fails.
• clearPersistedSession() clears both stores only for an explicit abandon
  flow.
• Restore continues to use browser-cpp-handles / handles /
  workspace-dir without a migration.

Verification:

• Focused tests distinguish handle-store calls from storage-area calls.
• Existing live-handle and snapshot-fallback restore tests pass.

Dependencies: None.

Files likely touched:

• src/ui/session-persistence.mjs
• scripts/e2e-session-persistence.test.mjs
• scripts/e2e-session-restore-choice.test.mjs

Estimated scope: Medium (3 files).

Task 2: Make startup gating support explicit persistence intents

Description: Adapt createPersistenceGate() so calls made while startup
restore is pending retain their intent. A queued workspace save must not be
downgraded to a state-only save; when enabled, the gate should perform the
strongest pending operation once. Add a debounced state-save entry point for
frequent editor changes, while keeping workspace acquisition saves immediate.

Acceptance criteria:

• A folder opened before restore completes is saved to IndexedDB after the
  gate enables.
• Multiple queued state changes coalesce without losing the latest state.
• An immediate workspace save is not delayed behind the editor debounce.
• Enabling the gate with no pending work performs no storage operation.

Verification:

• Extend persistence-gate tests for queued state, queued workspace, and
  coalescing behavior.

Dependencies: Task 1.

Files likely touched:

• src/ui/session-persistence.mjs
• scripts/e2e-session-persistence.test.mjs

Estimated scope: Small (2 files).

Task 3: Persist handles at workspace acquisition boundaries

Description: Wire the explicit workspace-save operation into the toolbar
paths that obtain a real directory handle. This includes openFolderWorkspace,
the folder acquired by saveUntitledDocument, and the folder reconnect path
used after snapshot-only restore. All ordinary tab, file, and workspace
mutations must use state-only persistence.

Acceptance criteria:

• A successfully opened or reconnected folder saves its handle immediately
  and records the corresponding serializable session state.
• Cancelling the picker or failing to open a folder writes neither store.
• Tab switches, tab closes, saves, file creation, filesystem refreshes, and
  other ordinary mutations do not touch IndexedDB.
• Explicitly abandoning a saved session clears both the handle and state.

Verification:

• Toolbar/session integration tests assert handle-store call counts and
  timing for open, reconnect, cancel, mutation, and abandon paths.

Dependencies: Tasks 1–2.

Files likely touched:

• src/ui/app.js
• src/ui/toolbar.js
• scripts/e2e-session-persistence.test.mjs
• scripts/e2e-session-restore-choice.test.mjs

Estimated scope: Medium (4 files).

Checkpoint: persistence boundaries

• Handle writes occur only at explicit workspace acquisition boundaries.
• Existing restore and startup-race tests pass.
• Snapshot-only sessions remain restorable when IndexedDB is unavailable.

Task 4: Preserve active editor state without unload persistence

Description: Make getOpenTabsSnapshot() include the current editor value
for the active tab instead of relying on a later tab switch. Schedule a
debounced state-only save from editor content changes after dirty state is
updated. Retain immediate state saves for lower-frequency structural changes.

Acceptance criteria:

• Editing the active tab and waiting for the debounce persists its latest
  content without a tab switch or unload event.
• Rapid edits coalesce instead of writing storage once per keystroke.
• Multiple tabs restore with the correct active path and latest captured
  contents.
• Editor-driven saves never open IndexedDB.

Verification:

• Add coverage for an edited active tab, multiple tabs, debounce
  coalescing, and state-only handle-store call counts.

Dependencies: Tasks 1–3.

Files likely touched:

• src/ui/app.js
• src/ui/toolbar.js
• scripts/e2e-session-persistence.test.mjs

Estimated scope: Medium (3 files).

Task 5: Remove asynchronous persistence from unload

Description: Change the beforeunload handler so it performs only the
existing synchronous worker termination. Do not flush, schedule, or initiate
session persistence from unload. Update the adjacent comment to document that
all session persistence is proactive.

Acceptance criteria:

• Closing the extension page does not call the persistence gate.
• Page unload cannot initiate indexedDB.open(), handleStore.save(),
  handleStore.clear(), or chrome.storage.local.set() through session
  persistence.
• STOP and its worker replacement remain unchanged.

Verification:

• Add a small testable lifecycle helper only if needed to assert the unload
  contract without importing the full UI bootstrap.
• Otherwise, cover the contract through focused persistence tests plus the
  Chrome close-path verification in Task 6.

Dependencies: Task 4.

Files likely touched:

• src/ui/app.js
• Optional: src/ui/lifecycle.mjs
• Existing E2E test file preferred; add/register a new file only if clearer.

Estimated scope: Small (1–2 files).

Task 6: Verify restore and the native close path

Description: Extend browser smoke coverage where it can accurately observe
the extension target closing and the Chrome process remaining alive. Do not
allow hosted-page fallback to count as issue #92 verification. Because the
automation harness may not be able to obtain a genuine
FileSystemDirectoryHandle, retain a required manual test on the affected
Chrome/macOS environment.

Acceptance criteria:

• Automated close coverage closes the extension tab, waits a bounded
  interval, and proves the controlled Chrome process/connection is still alive
  before normal cleanup.
• The issue-92 smoke path fails or reports unsupported if it cannot load the
  extension; it does not pass through hosted fallback.
• Manual testing with a real empty folder no longer crashes Chrome.
• Relaunch restores the workspace and tabs from proactively persisted
  state.

Verification:

• Fully quit and relaunch Chrome before the manual run.
• Test open/close with no folder.
• Open an empty folder, wait for persistence, close, relaunch, restore, and
  close again.
• Open the original project without running it and close.
• Run and STOP the original infinite-loop program, then close.
• Confirm Chrome remains alive and no new crash report is uploaded.

Dependencies: Task 5.

Files likely touched:

• scripts/smoke-browser.mjs

Estimated scope: Small (1 file).

Final checkpoint

• npm run test:e2e
• npm run lint
• npm run build
• npm run test:browser:chrome
• Manual native-handle test matrix passes on Chrome/macOS.
• The PR documents any automation limitation and includes Closes #92.
• A human reviews and merges the PR; no agent merges it.

Risks and mitigations

Risk	Impact	Mitigation
Removing unload persistence loses a very recent edit	High	Capture the live active-editor value and debounce state-only persistence during editing; test close after the debounce settles.
Folder open races startup restore	High	Preserve persistence intent in the startup gate and give workspace saves priority.
API split misses a handle-acquisition path	High	Classify every existing caller first and test open, reconnect, and save-to-folder flows.
IndexedDB failure prevents all session restore	Medium	Continue serializable state persistence after handle-save failure and retain snapshot fallback.
Automated smoke uses a fake handle and misses the native bug	High	Require manual verification with a real showDirectoryPicker() handle on the affected environment.
Chrome still crashes after removing unload storage	Medium	Re-run the same IDBFactory.prototype.open discriminator, capture a new Crash Report ID, and investigate any remaining unload-time IndexedDB caller before revisiting unrelated output/worker hypotheses.

Plan status

This replacement plan is ready for human review. It is not approval to begin
implementation.

[kbuffardi]

@kbuffardi: "implement the plan and raise a pr"

Codex (GPT-5) implemented the approved IndexedDB/unload-persistence plan on fix/issue-92-indexeddb-unload and opened PR #94:

• fix: avoid IndexedDB handle writes during tab unload #94
• separates directory-handle persistence from serializable state saves
• persists handles at folder acquisition/reconnection boundaries
• proactively debounces active-editor state
• removes asynchronous persistence from beforeunload
• leaves STOP and worker replacement behavior unchanged

Verification completed:

• npm run test:e2e — 199 passed
• npm run lint — passed
• npm run build — passed with existing bundle-size warnings
• Chrome compiler/link preflight — passed
• Chrome hosted smoke — reached the existing unrelated xterm terminal-text assertion failure; the real native directory-handle close path remains a required manual check in the PR
