Gives the Electron desktop client a genuine offline mail replica: mail is
READABLE with no network, not merely searchable. Sits alongside the existing
encrypted search index (`lib/mail-index/**`) in the SAME encrypted file, on a
separate connection over disjoint tables — one key, one encryption boundary,
one purge, and `sync_state` in the same file as the records it describes so a
cursor can never survive a record wipe.
Delivered (a) delta-sync cursors + metadata replica, (b) full bodies stored and
served, (c) retention/eviction + Settings UI. Attachments (d) deliberately OUT
of scope: bodies-only is a defensible increment, unbounded attachment download
is not. Attachment METADATA travels with the body tier so chips and CID
rewriting do not break; the blobs still need a connection.
## Architecture, and why the review's findings did not come back
`docs/ELECTRON-OFFLINE-ENGINE-REVIEW.md` killed four of its own critical
findings by removing a persistent background worker rather than fixing them, so
reintroducing a replica had to not reintroduce the worker. It does not:
C1 - still fixed, untouched: no new dependency, both `docker build`s unaffected.
C2/C3/C4/H1/H4 - still MOOT, and for the same reasons. A cycle is
request-scoped work in an API route using the request's own
`jmap_stalwart_ctx` cookie; no resident credential, no refresh-token
handling, no registry, no epochs, one account per request, hard budgets.
H2 - still fixed: the key crosses on the inherited fd and is zeroed per job.
H3 - BACK IN SCOPE, and answered. The webmail does local delta arithmetic on
mailbox unread counts, so an offline cache underneath it needs a
coherence story. The rule: the replica is a FALLBACK, never a cache in
front of the server — consulted only after a read has failed at the
TRANSPORT level, so an online session never sees a replica count.
Enforcing H3's rule needed a real signal, because `lib/jmap/client.ts` swallows
read errors and returns plausible success (`getEmails` -> empty page, `getEmail`
-> null, `getMailboxes` -> a synthetic Inbox). Hence `lib/jmap/transport-health.ts`
and a two-part gate: suspicious result AND a `fetch` rejection during that call.
## Correctness carried over from the mobile client, by name
- Cursor provenance as branded types: `advanceCursor` cannot accept a
`SnapshotState`, so adopting an `Email/get` state as an `Email/changes` cursor
is a compile error. Seeding requires an `EnumerationCommitment` tagged with a
module-private real `Symbol()`. Tests assert the mint sites by grep.
- Mandatory bootstrap order: capture both cursors BEFORE enumerating.
- `Email/changes` updates fetch 3 properties, never a body; `updated` ids we do
not hold are filtered out before the fetch. Mailbox destroys delete the
mailbox row only. An empty page still advances the cursor.
- Exactly ONE error class moves a cursor. `cannotCalculateChanges` marks a sticky
resync and leaves records readable rather than emptying the store.
- Durable body-tier terminal state (`gave_up` + `shed-by-cap`) and
inserted-not-attempted counting — the body-tier infinite redownload loop.
- Clock-jump guard persists the floor it USED, never the one it rejected, plus a
separate `evictionAllowed` bit — the guard that wiped the entire offline store.
- Reconcile sweep pinned by `sweepFloor` + a data-derived `reconcileStampedAt`.
## Verification
- typecheck clean; 86 new unit tests (2465 total, up from 2379). Every named fix
was RE-BROKEN and confirmed to fail a test (8 gates). Two weak/vacuous tests
were found and repaired.
- Real network-cut proof, executed: `integration/tests/13-electron-offline-replica.spec.ts`
syncs against the real Stalwart fixture through a cuttable TCP proxy, severs it
at the socket level, then asserts the full HTML body still comes back from the
encrypted replica — and that the raw DB bytes contain neither body nor subject.
Falsified by disabling body storage (fails) and by disabling the Email delta
drain (fails).
- Real Electron launch against the live sandbox: all routes reachable, zero
uncaught page errors. Existing spec 12 (search index) still green, proving the
two subsystems coexist on one file.
Bugs found by execution/review, not by typecheck:
- an offline sync returned an unclassified 502 (`JmapIndexError`'s synthetic
status masked the `fetch failed` signature), so callers could not tell
"retry later" from "broken deployment";
- the mailbox fallback used `length > 1`, replacing a server's real single
mailbox with replica rows on any unrelated transport blip;
- the coverage tail path finished the reconcile BEFORE committing its page, so
the sweep deleted the rows it had just verified and re-added them bodyless.

Adds integration/tests/12-electron-mail-index.spec.ts (3 tests, all passing
against the real Stalwart fixture) and fixes what running it exposed. None of
these were visible from reading the code.
1. JMAP session fetch never followed a redirect. Stalwart 307-redirects
/.well-known/jmap to /jmap/session, and fetchJmapSession used
`redirect: 'manual'` and treated any non-2xx as failure - so every reindex
died with "JMAP session fetch failed (307)". Now follows up to 3 hops and
REFUSES to follow off-origin, because the user's credentials ride on every
hop; a blind `redirect: 'follow'` would hand the Authorization header to
whatever host a misconfigured session pointed at. Same bound and same
reasoning as lib/auth/verify-jmap-auth.ts.
2. The fd-3 key channel could only be adopted once per process, but its state
was module-scoped. Next re-evaluates route modules, so a second instance hit
`Could not open fd 3: Error: open EEXIST` from libuv. State moved to a
Symbol on globalThis - the one place in a Node process that survives module
re-evaluation.
3. Next's output file tracing does NOT carry @signalapp/sqlcipher's prebuilds/
into .next/standalone. It traced the package's JS and its node-gyp-build
dependency, but node-gyp-build resolves the .node binary by scanning a
directory at runtime, which no static tracer can follow - so `require()`
would have failed in every packaged build. scripts/assemble-standalone.mjs
now copies it, alongside the public/ and .next/static copies it already does
for the same "standalone output omits things" reason. All six platform/arch
prebuilds are copied, not just this host's, because electron-builder
cross-builds the x64 and arm64 macOS targets from one runner.
The three tests, and why it takes three - two constraints made a single
configuration impossible, and both were measured rather than assumed:
* The renderer cannot reach this fixture from a production build. Its CSP
pins connect-src to `'self' https: wss:` and the fixture's Stalwart is
plain HTTP. NODE_ENV=development at RUNTIME does not help: `next build`
INLINES process.env.NODE_ENV into the compiled middleware, so proxy.ts's
`isDev` is frozen at build time (observed: a standalone server started with
NODE_ENV=development still served the production CSP).
* The fd-3 channel cannot survive `next dev`, which forks its server with an
IPC channel that claims fd 3 (EEXIST); fd 4 there is not a pipe either
(ENOTTY).
So: PIPELINE drives the real standalone server over HTTP from Node with a
real fd-3 key channel (no browser, so no CSP) and asserts a real SMTP
delivery is findable by a word from its BODY, with a real snippet and
contextBlock, idempotent catch-up, working type filters, and - reading the
raw bytes of the .db AND its -wal - that nothing is recoverable in cleartext.
TRIGGER proves the event-driven wiring: a real delivery makes the renderer
POST /api/offline/reindex off its live push. WIRING launches the real shell
with no ELECTRON_LOAD_URL and asserts the routes are reachable (401, not 404
or 503) with real safeStorage behind them.
Each test now gets its own --user-data-dir. That is load-bearing, not hygiene:
Electron reuses one profile across launches, and a leftover jmap_stalwart_ctx
cookie from an earlier run made the WIRING test's 401 assertion pass as a 200.
Verified: typecheck clean; unit suite 2379 tests with the SAME 3 pre-existing
failures as the base commit b15098a6 (2 builtin-themes, 1 jmap-client-
resilience) and 48 net new passing; both `docker build`s succeed; the
hosted-deployment gate returns 404 with an empty body and materialises no file
in the production image; e2e/electron-smoke 4/4; 11-electron-notification
still passes.

Phase 1 step 7 of VNCprodbuild. integration/tests/11-electron-notification.spec.ts
launches the actual Electron shell, logs in as alice against this repo's
existing docker-compose Stalwart fixture, injects a message over real SMTP
(same helpers/smtp.ts sendMail() 02-mail-sync.spec.ts uses), and asserts a
native notification fires via electron/main.ts's __notificationCallCount
test hook - proving the full real pipeline, not just the synthetic IPC call
step 3's smoke test exercises: SMTP -> Stalwart -> JMAP push
(lib/jmap/client.ts) -> stores/email-store.ts's handleStateChange ->
handleNewEmailNotification -> the page effect -> lib/electron-bridge.ts ->
the contextBridge/IPC bridge -> electron/main.ts's Notification call.
Runs against a `next dev` server (electron/main.ts's new ELECTRON_LOAD_URL
escape hatch), not the standalone build, because this fixture's Stalwart is
deliberately plain HTTP and production's CSP correctly refuses non-TLS
connections - the identical trade-off integration/webmail.Dockerfile already
makes for the browser-based suite. New playwright.integration-electron.config.ts
+ global-setup-electron.ts (brings up only the `stalwart` compose service,
not `webmail`, which this suite never touches and which may not even be
startable on a given host - see its own header comment) keep this fully
separate from the main dockerized integration run, which has no Electron
binary compatible with that container's platform; playwright.integration.config.ts
gets a matching testIgnore so a plain `npm run test:integration` never tries
to sweep this file in. Wired as `npm run test:integration:electron`.
On "the real WebSocket path": confirmed against this fixture's actual
`stalwartlabs/stalwart:v0.16` (same as the sandbox server) that its
/jmap/ws requires the same Authorization header as every other JMAP
endpoint on the handshake itself, which the browser WebSocket API cannot
attach - so the WS attempt reaches the network correctly (see the CSP fix
in the previous commit) but always fails auth here, and the circuit
breaker falls back to SSE within about a second. That fallback is what
delivers the push this test observes - documented in detail in the spec's
header comment, including why asserting the WS handshake itself succeeds
here would be asserting something that cannot be true from a browser
against this specific server.
Known flakiness, root-caused not eliminated (see
playwright.integration-electron.config.ts's retries: 2 and its comment):
`next dev`'s on-demand route compilation + Fast Refresh occasionally races
the SSE stream during the login -> inbox transition and drops that one push
event with no error anywhere - reproduced by running the identical test
repeatedly against an already-warm stack (IT_NO_DOCKER=1): identical
request sequence logged every time, but the outcome wasn't always the same.
This is specific to the dev-server workaround this test needs for the
plaintext-Stalwart fixture, not a bug in the feature it's verifying - the
WS circuit breaker and SSE fallback fire exactly as designed in every run's
own logs, pass or fail.
Verified: passed cleanly standalone multiple times; with retries: 2 in
place, passed within the retry budget on every attempt made.
The explicit Email/set destroy workaround for the duplicate-on-move bug is
removed now that the root cause is filed upstream (support.stalw.art #1150:
onSuccessDestroyOriginal destroys the copy's create-id instead of the source
id). copyEmailAcrossAccounts keeps requesting onSuccessDestroyOriginal, so the
move self-heals once Stalwart ships the fix.
Kept: the keyword-preservation fix (carry the source keywords into Email/copy)
so the moved message keeps its read state.
Tests: 08-shared-moves still asserts delivery + read-state on every
cross-account case; the source-removal checks are re-pinned test.fail, scoped
to a nested describe, until #1150 is fixed. Suite green (5 pass, 3 expected-fail).
Moving a message across the account boundary (own ↔ shared folder, or
between two owners' shared folders) left the original in the source
folder and showed the moved copy as unread. Same-account moves were fine.
Cause (verified against a live Stalwart):
- Email/copy drops keywords unless the create sets them, so the copy lost
$seen and arrived unread.
- onSuccessDestroyOriginal is unreliable — the implicit destroy reports
notFound and leaves the original behind (flaky), so the move duplicated.
Fix (copyEmailAcrossAccounts): read the source keywords and carry them
into the Email/copy create, then destroy the original with an explicit
Email/set on the source account instead of onSuccessDestroyOriginal.
Tests: 08-shared-moves now asserts the source is gone and the read state
survives on every cross-account case, and adds a cross-owner shared →
shared move (alice's folder → bob's folder). Confirmed red on the old
code (3 cross-account cases fail), green with the fix.
Moving a message to a folder in another account (own ↔ delegated/shared) via the
"Move to" context menu was a no-op — the handlers always issued a single-account
Email/set, which can't move between JMAP accounts. Drag-and-drop already routed
these correctly; the context menu never did.
Add moveToMailboxCrossAware: it detects a cross-account destination (own and
shared mailboxes both carry accountId) and routes through the drag-and-drop
crossAccountMoveEmails pipeline, else falls back to the single-account move.
Fix the pipeline for delegated folders too: a client can't stage a blob in a
delegated account (Blob/upload → blobNotFound), so importing into a shared folder
failed. When one client reaches both accounts, use a server-side JMAP Email/copy
(+ destroy original) instead of blob copy+import; the blob path is kept only for
separate cross-server login accounts. Adds client.copyEmailAcrossAccounts.
Unit tests for the dispatch; the two 08-shared-moves specs are un-pinned. Full
docker integration suite green (37 passed).
Reopening a draft reset the composer's From to the default identity. The
edit-draft handler matched the draft's saved From against the active-account
identity list by email only, so two identities sharing an address (a default +
an alias differing by name) collided — the wrong one was picked, or with
cross-account namespaced ids none was.
Add findDraftIdentityId (name+email, normalized, +tag fallback) and match against
the same list the composer renders (the flat cross-account list when multi-
account is on). Wired into both the classic and Pro edit-draft paths. Unit tests
plus the un-pinned 07-drafts integration spec.
Extend 04-shared-identity's UI test to not just assert team@example.org is
offered but to actually select it as the sender and confirm it becomes the
active From identity, then hold on the composer so the selected group address is
visible in the recorded video. Adds selectComposerFrom / selectedComposerFrom
helpers.
Feat/unified mailbox account scope
Rework the sidebar "All accounts" into an account-bounded "Unified Mailbox"
by default, with cross-account merging as an opt-in (admin-gated) sub-option.
The standalone per-account "All Mail" virtual folder is folded into the unified
All mail / Unread / Starred entries.
Conflict resolution notes:
- stores/settings-store.ts: both main and this branch independently added a
per-account default-identity (#507) migration at different versions (main v6,
branch v7). Merged migration is version 7 using the refactored migrateSettings
function; the unified-mailbox rework is guarded at `version < 7` so users who
stopped at main's interim v6 identity bump still receive it, while the #507
identity-map coercion stays at `version < 6` so their populated map is kept.
- stores/auth-store.ts: kept main's applyPreferredIdentity (superset with the
pre-#507 legacy migration).
- stores/email-store.ts: removed the ALL_MAIL_MAILBOX_ID paths (folded into the
unified views) while preserving main's plugin hooks (onSearchResults /
onEmailsFetched); adopted advancedSearchCrossViewEmails for advanced cross-view
search.
- components/settings/layout-settings.tsx: kept main's faviconUnreadBadge setting
alongside the new unifiedCrossAccount toggle.
- integration/: union-merged the two independently-authored suites - branch suite
is authoritative (matches new behavior) with main's shared-identity (#569) group
infrastructure preserved.
- components/email/email-composer.tsx: dropped a duplicate data-testid attribute
introduced by the auto-merge.
Provision a Stalwart group (team@example.org) with carol as a member before her
first login, and assert the composer's From selector offers the group address.
This confirms the group-membership scenario of #569 already works out of the
box: Stalwart returns the group's send-as identity on the member's own account,
so the app's normal single-account identity load surfaces it (identities.length
> 1 -> the From <select> renders with team@).
- stalwart: create the `team` Group in plan-accounts and add carol via
User.memberGroupIds in the entrypoint (id resolved after apply, like
DOMAIN_ID). carol, not alice/bob, so the sync specs stay unshared.
- helpers: GROUP config, openComposer/composerFromOptions, and JmapClient
accounts + sharedAccountNames (Identity/get needs the submission capability).
- composer: add data-testid="composer-from" to the From <select> and its
single-identity <span> fallback.
Ref: https://github.com/bulwarkmail/webmail/issues/569
Add an end-to-end integration harness that runs the webmail against a real
Stalwart mail server in Docker and drives it with Playwright, focused on the
mail/folder synchronisation behaviour (unread/total counters, folder-list
sync, account-scoped Unified Mailbox) that the unified-mailbox work touches.
- integration/ stack: Stalwart (declarative bootstrap: alice/bob/carol,
submission + IMAP listeners, permissive CORS) + webmail (dev mode, so the
browser's plaintext cross-origin JMAP calls aren't blocked by the prod CSP).
- Helpers: dependency-free SMTP submit client, JMAP client for seeding /
inspecting server state, and page helpers (login, add/switch account,
locale-independent folder-counter reads).
- Specs: login, single-account sync (receive/read/move/delete/folder-create/
burst) and multi-account (per-account isolation + cross-account Unified
Inbox aggregation + background-account delivery). 12 tests, all green.
- Add focused data-testid hooks to the mail UI (folder rows + counters, email
list items, account switcher, composer) for stable selectors.
- Exclude examples/ and integration/ from tsconfig/eslint/.dockerignore.
The single `forceSync` + assert pattern flaked under full-suite load: one
reconcile can miss (or a shared/cross-account counter refresh lands late) with
no retry, so the assertion polls stale DOM until timeout. The flake moved
between reconcile-dependent tests (server-side move, spam source drain, unified
/ shared counters) run to run.
- Add expectFolderCountsSynced(): nudges a reconcile (visibilitychange ->
checkForStateChanges) before *every* poll, so a missed reconcile is retried
for the full window. Compares only the provided unread/total fields.
- Use it for the reconcile-dependent counter checks in 02 (move/delete),
03 (multi-account isolation + unified aggregation), 04 (All Mail), 05 (spam
source), 06 (shared folders); drop the now-redundant standalone forceSync.
Pure live-push assertions (incoming/burst, background-login-live) keep the
plain helpers so they still prove push works.
- The spam->not-spam round-trip could stall the Junk badge reconcile even with
retries under load; assert the optimistic list removal + authoritative server
round-trip (out of Junk, back in Inbox) instead of the badge.
Validated with two back-to-back full-suite runs: 35 passed each.
Extend the cross-account blob routing beyond download/preview to every blob
fetch in the message viewer, so a message opened from a different account in the
unified / All-Mail view renders and exports correctly instead of 404ing against
the active account:
- inline cid: images, drag-to-desktop, attachment thumbnails, the "download all"
zip bundle, and the S/MIME / TNEF / embedded-rfc822 blob reads now use a
resolved blobClient (getClientForAccount(sourceClientAccountId)) and the owner
blobAccountId (sourceAccountId), computed once from the open message's source;
- fetchBlobAsObjectUrl / fetchBlobArrayBuffer / fetchBlob calls pass the
accountId (the client methods gained the param in the previous commit);
- non-cross-account behaviour is unchanged (blobClient === active client).
Extends 10-attachments with an inline-image case (verified to fall back to the
placeholder without the routing). The SMTP helper can now send multipart/related
inline images.
Blobs are scoped per JMAP account, but the attachment download/preview path
always used the active account's client and accountId. Opening a message from a
different account in the unified / All-Mail view and downloading (or previewing)
an attachment therefore 404'd against the active account.
Route the blob fetch to the message's source instead:
- resolveBlobSource() picks the owning login's client
(getClientForAccount(sourceClientAccountId)) and the owner accountId
(sourceAccountId) for delegated/shared blobs, in the unified view;
- handleDownloadAttachment + the attachment-preview handlers use it;
- downloadBlob / fetchBlobAsObjectUrl / fetchBlobArrayBuffer gain an accountId
param (getBlobDownloadUrl/fetchBlob already had one).
Adds 10-attachments: an attachment on another account's All-Mail message
downloads with the correct bytes (verified to fail without the routing).
Add 09-live-counters: a background-login account updates the unified counter
live (no reconcile), and a shared-folder change reconciles the All-Mail counter
on focus. Document the shared-account counter behaviour in the README.
Add draft and shared-folder-move coverage (suite now 31 tests). Findings are
asserted server-side or pinned with test.fail where the UI is incomplete.
Drafts (07):
- multiple recipients (committed and typed-but-uncommitted) persist, and the
draft reopens via the continue-draft button;
- a server-created draft (with $draft) shows the continue-draft button;
- a changed sender identity is saved to the draft on the server;
- KNOWN BUG (test.fail): reopening a draft resets the From selector to the
default identity instead of the one the draft was saved with.
Shared-folder moves (08):
- shared -> shared (same owner) moves work in both directions (server-verified);
- KNOWN LIMITATION (test.fail): cross-account moves (own account <-> shared
folder) don't relocate the message — the Move-to submenu offers the target
but clicking it is a no-op.
Hooks added: composer From select + save-status, viewer edit-draft button,
context-menu "Move to" submenu + per-target testids (testId on
ContextMenuSubMenu). Helpers: JMAP identities/createDraft/sharing, composer
drive + move-via-submenu. README documents the findings.
Extend the integration suite (now 22 tests) to cover:
- All Mail view (04): single-account merge of Inbox + custom folders with
Junk excluded, and cross-account aggregation across every logged-in account.
- Message actions from the list context menu (05): mark read/unread, delete
(→ Trash), mark-as-spam (→ Junk) and not-spam round-trip, verified on both
the UI counters/row state and the server mailbox the message ends up in.
- Shared/delegated folders (06): a delegated folder (+ Trash/Junk) shared
alice→carol; the shared folder renders with its counter, and read/unread/
delete/spam performed there land correctly (server-verified).
Hooks added: data-testid on context-menu delete/spam/read-unread items
(via a testId prop on ContextMenuItem), data-shared on folder rows, and
testId/data-expanded on sidebar section headers to drive the Shared section.
Observations surfaced by the suite (asserted server-side / with a reconcile):
- mark-as-spam doesn't optimistically decrement the *source* counter the way
delete does; a visibility reconcile settles it.
- shared *destination* counters (shared Trash/Junk) don't refresh live —
forceSync reconciles the active account only, not shared accounts.
Add an end-to-end integration harness that runs the webmail against a real
Stalwart mail server in Docker and drives it with Playwright, focused on the
