Root cause: WhatsApp Web stores pkmsg as ciphertext first, then decrypts
to interactive. React does not re-render the ciphertext→interactive
transition, requiring F5. When enc type is msg (established session),
Web receives as interactive directly and renders in real-time.
Changes:
- messages-send.ts: re-enable biz node for carousel (CDP evidence from
Pastorini confirms native_flow v=9 name=mixed + quality_control),
LID-based addressing for session reuse, blocking tctoken fetch,
force device-identity, skip bot node for carousel
- messages.ts: interactiveMessage direct (no viewOnceMessage wrapper),
skip Message.create() for carousel (oneOf corruption), skip ephemeral
contextInfo for carousel
- messages-media.ts: fix jimp type check (function not object)
- tc-token-utils.ts: dual storage under LID and PN for reliable lookup

7 corrections based on reverse-engineering of WhatsApp Business Android:
1. resolveCanonicalJid: PN→LID resolution for transaction lock keys (prevent race conditions)
2. Retain PN session during LID migration (avoid No Session errors)
3. Delayed PreKey deletion with 5-min grace period (prevent Invalid PreKey ID races)
4. Surgical session cleanup: only delete the specific corrupted device, not all devices
5. Identity dual storage: save identity key in both LID and PN addresses
6. MAC error cooldown reduced 10s→1s (faster recovery, aligned with WABA)
7. Allow session recreation on first retry (retryCount >= 1 instead of > 1)
* fix: remove unused jidDecode import from decode-wa-message.ts
* fix: add try/catch to delayed PreKey deletion to prevent unhandled rejection
The setTimeout async callback in removePreKey could cause unhandled promise
rejection if the keystore was destroyed (connection closed) before the
5-min grace period expired.
The web protocol (WA\x06\x03) requires a web-compatible UserAgent.
Using SMB_ANDROID in the UserAgent caused pair code registration to
fail with "cannot connect device" even though the phone confirmation
appeared. The Android identity is now only set in DeviceProps.platformType
(ANDROID_PHONE) in the registration node, which correctly determines
the display name in "Linked Devices" as "Android (14)".
Changes:
- getUserAgent(): always returns MACOS platform and Desktop device
- getClientPayload(): always includes webInfo (no longer skipped for Android)
- Remove unused isAndroidBrowser import from validate-connection.ts
- Update pair code comments documenting tested platform IDs
- Add structured logging to pair code request
* feat: add Android browser preset for companion device registration
Add Browsers.android(apiLevel) preset that identifies as an Android
companion device (SMB_ANDROID platform, ANDROID_PHONE device type).
Validated against Frida captures of real WhatsApp Android protocol.
* feat: support BAILEYS_BROWSER env var for browser selection
Allows selecting Android companion mode via environment variable
without code changes. Set BAILEYS_BROWSER=android (or android:15
for a specific API level) to register as an Android device.
* fix: auto-detect Android browser in pair code and fall back to Chrome
Pair code companion registration fails with Android browser because the
WA server rejects the ANDROID_PHONE companion_platform_id over the web
Noise protocol. When Android is detected, requestPairingCode() now
transparently uses Chrome/macOS platform values for the pair code stanza
while QR code pairing continues to work as Android (SMB_ANDROID).
* docs: add android to isValidBrowserPreset JSDoc
* fix: break infinite Bad MAC + session recreation loop
Remove aggressive session cleanup from the decryption hot path that caused
cascading failures when multiple messages from the same contact arrived
simultaneously. The Signal Protocol naturally recovers via retry+pkmsg flow.
Changes:
- Remove cleanupCorruptedSession() from per-message error handler (hot path)
- Move session cleanup to retry-exhausted handler as safety net
- Add per-JID retry request deduplication (5s window)
- Add 10s cooldown on MAC error session recreation
- Export cleanupCorruptedSession/getDecryptionJid for use in messages-recv
Tested: corrupted session with fake keys → Bad MAC → retry receipt →
pkmsg recovery → all 7 messages delivered, zero infinite loop.
* fix: address PR review — lint, dedup scope, and cleanup targeting
- Remove unused `autoCleanCorrupted` param from decryptMessageNode (lint fix)
- Scope retry dedup by participant JID in group chats (not group JID)
- Move dedup registration after early-return checks to avoid blocking
subsequent messages when max retries reached
- Use participant JID for session cleanup in groups (Signal sessions
are per-participant, not per-group)
* feat: centralized LID→PN normalization for all emitted events
WhatsApp's server increasingly uses LID (Linked ID) as the primary
addressing format. Consumers expect phone numbers (PN),
not opaque LID identifiers. This adds comprehensive LID→PN resolution
across all ev.emit() paths so downstream consumers always receive PN.
Key changes:
- Add resolveLidToPn() and normalizeKeyLidToPn() centralized helpers
in process-message.ts for consistent LID→PN resolution
- normalizeMessageJids() fast path: use alt JID directly from stanza
attributes (zero I/O, eliminates race condition with LIDMappingStore)
- Await storeLIDPNMappings() before normalization in message receipt
flow (was fire-and-forget, could race with subsequent getPNForLID)
- Normalize LID→PN in all event emission points:
* messages.upsert (keys, nested reaction/poll keys, participantAlt)
* presence.update (jid + participant)
* message-receipt.update (key + userJid)
* contacts.update (picture notifications)
* blocklist.update (blocklist JIDs)
* call events (chatId, from)
* group metadata (participants, owner, subjectOwner)
* group notifications (acting participant, add/remove/promote/demote)
* newsletter notifications (author, user JIDs)
* sync actions (mutation index normalization)
- Make handlePresenceUpdate and handleGroupNotification async to
support await on LID resolution
- Add normalizeGroupMetadata() helper in groups.ts for all
extractGroupMetadata call sites
Performance: ~0.01ms per message (LRU cache hit). No impact on
message sending. First-contact resolution ~2-5ms (one-time per contact).
* fix: normalize LID→PN in handleBadAck, media retry, and PDO recovery
Additional leak points found during final audit:
- handleBadAck: key.remoteJid from ack stanza could be LID
- messages.media-update: media retry key JIDs not normalized
- CTWA PDO recovery: webMessageInfo.key from phone response not normalized
* fix: address PR review — parallelize LID resolution, use helper consistently
- normalizeGroupMetadata: resolve participant LIDs with Promise.all
instead of sequential loop (perf on large groups)
- handleCall: resolve participant JIDs with Promise.all
- handleBadAck: use normalizeKeyLidToPn() helper instead of manual
resolveLidToPn + assignment (consistency with other code paths)
- CB:relay: resolve callCreator LID→PN before emitting
* fix: add timeout to fetchLatestBaileysVersion to prevent hanging connections
AbortController with 5s default timeout prevents indefinite blocking
when GitHub is unreachable (DNS failure, network issues). Falls back
to bundled version via existing catch block. Ref: Baileys#2385.
* fix: move clearTimeout to finally block in fetchLatestBaileysVersion
Ensures timer cleanup on both success and fetch rejection paths,
preventing dangling timers when DNS/network fails before abort fires.
In DMs, when the connected user sends a reaction, the inner key's
remoteJid could remain unnormalized (e.g. LID vs PN), preventing
correct matching with the original message. Also normalises participant
in groups for own messages — an improvement over upstream Baileys#2386.
* feat: apply PR #2339 missing commits (ced3305 + fe5a37c)
Apply two Feb-19 commits from WhiskeySockets/Baileys PR #2339 that
were missing from the initial integration:
ced3305 — Prevent tctoken attachment to peer (AppStateSync) messages
- Add isPeerMessage guard: additionalAttributes?.['category'] === 'peer'
- Exclude peer messages from is1on1Send to fix error 479 (SmaxInvalid)
which was causing hundreds of rejections on multi-device sync JIDs
fe5a37c — Error 463 retry logic + blocking→non-blocking refactor
- Replace blocking await getPrivacyTokens() with fire-and-forget .then/.catch
so the send path is never delayed by a token fetch
- Add tcTokenRetriedMsgIds Set in messages-recv.ts to track retried msgIds
- On error 463 (MissingTcToken): wait 1.5s then relay the message once,
allowing the server's tctoken notification to arrive before resend
- Add retry_463_ok log event to baileys-logger for observability
- Add `yarn lint:fix` step before lint check to auto-fix prettier/import-sort
formatting issues (runs with continue-on-error to not block)
- Fix circular conflict between prettier and space-before-function-paren
rule in cache-utils.ts via eslint-disable comment

Previously the same `text` field was used for both header.title and body.text,
causing duplicate content to appear. Now `title` controls the header (defaults
to a space like Pastorini) and `text` controls the body independently.

Remove messageContextInfo (deviceListMetadata) from viewOnceMessage wrapper
in generateButtonMessage and remove empty subtitle from header. This fixes
CTA mixed buttons (url, copy, call) not being delivered to iOS devices -
same pattern that fixed carousel messages.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Flatten image validation nesting to max 4 levels (eslint max-depth)
- Collapse multi-line ternary to single line (prettier)
- Add missing blank line before statement
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Lint fixes:
- Replace `any` types with proper proto interfaces (IInteractiveMessage)
- Fix missing blank lines before statements (eslint padding-line-between-statements)
- Fix unused variable and indentation in protocol dump
- Remove pre-existing `any` casts in createParticipantNodes
Review feedback (Copilot/Codex):
- Gate protobuf roundtrip test and protocol dump behind debug level
(avoids CPU overhead and sensitive data exposure in production)
- Add empty array validation for nativeButtons (fixes [].every() edge case)
- Support headerTitle in quick_reply buttonsMessage (HeaderType.TEXT)
- Fix stale comment that said "wrap viewOnceMessage" when code sends direct
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Carousel (interactiveMessage):
- Remove messageContextInfo from carousel (breaks iOS delivery)
- Remove empty subtitle field from card headers
- Add jpegThumbnail/dimensions validation for card images
- Return direct interactiveMessage at root (no viewOnceMessage wrapper)
- Skip DSM (deviceSentMessage) for own devices (causes error 479)
- Skip bot node injection for carousel messages
Quick Reply Buttons (buttonsMessage):
- Separate quick_reply buttons from CTA buttons in generateWAMessageContent
- quick_reply (reply only) uses legacy buttonsMessage format (works on Android + iOS + Web)
- CTA buttons (url, copy, call) use nativeFlowMessage with viewOnceMessage wrapper
Stanza construction (messages-send.ts):
- Defer biz/bot nodes to be appended LAST (after device-identity, tctoken)
- Fix button name extraction for carousel (flatMap from cards)
- Add protobuf roundtrip test and protocol dump for debugging
Tested: Carousel renders on Android + iOS. Quick reply buttons render on Android + iOS + Web.

Applied yarn lint --fix to auto-correct:
- Import spacing and sorting across multiple files
- Trailing commas
- Arrow function formatting
- Object literal formatting
- Indentation consistency
- Removed unused imports (BaileysEventType, jest from tests)
This commit addresses the linting errors reported in GitHub Actions:
- Fixed import ordering in libsignal.ts
- Fixed trailing commas in Defaults/index.ts
- Cleaned up formatting across 63 files
- Reduced line count by ~220 lines through formatting optimization
Note: Some lint errors remain (75 errors, 239 warnings) mainly:
- @typescript-eslint/no-unused-vars (variables assigned but not used)
- @typescript-eslint/no-explicit-any (type safety warnings)
These remaining issues are non-blocking and can be addressed incrementally.

**Root Cause:**
The BaileysEventStream class overrode the on()/off() methods to use a custom
handler system (this.handlers Map), but emit() calls used the native EventEmitter.
This caused control events (backpressure, drain, dropped, etc) to be emitted but
never received by listeners.
**Changes:**
- Modified on() to use super.on() for control events (backpressure, drain, dropped, batch-processed, retry)
- Modified off() to use super.off() for control events
- Kept custom handler system for Baileys events (messages.upsert, connection.update, etc)
- Now control events use native EventEmitter while Baileys events use custom system
**Tests:**
- ✅ Backpressure event tests now passing (was timing out before)
- ✅ Drain event tests now passing (was timing out before)
- Reduced test failures from 34 to 33

Addresses GitHub Copilot review feedback from PR #148:
## Critical Fix - Cache Key Mismatch (Issue #1 & #2):
**Problem:** Metadata was stored using `messageKey.id` but retrieved using
PDO response `stanzaId`, causing cache lookups to always fail. This completely
broke the metadata preservation system.
**Root Cause:**
- Store: `cache.set(messageKey.id, metadata)` ← message ID
- Retrieve: `cache.get(response.stanzaId)` ← PDO request ID
- These are DIFFERENT IDs, so metadata was NEVER recovered
**Solution (messages-recv.ts:167-217):**
1. Use message ID temporarily to prevent duplicate requests
2. Send PDO and obtain stanzaId (PDO request ID)
3. Store metadata using stanzaId as key (matches response lookup)
4. Clean up temporary message ID marker
5. Timeout cleanup now uses stanzaId
**Flow Now:**
```
1. Check duplicate: cache.get(messageKey.id) → prevents spam
2. Mark as requested: cache.set(messageKey.id, true)
3. Send PDO → returns stanzaId
4. Store metadata: cache.set(stanzaId, metadata) ← CRITICAL FIX
5. Clean marker: cache.del(messageKey.id)
6. Response arrives: cache.get(stanzaId) ← NOW WORKS! ✅
```
## Type Consolidation (Issue #4):
**Problem:** `PlaceholderMessageData` defined separately in both
messages-recv.ts and process-message.ts (as CachedMessageData).
**Solution:**
- Consolidated into single shared type in src/Types/Message.ts
- Exported via src/Types/index.ts
- Both files now import from shared location
- Prevents definition drift and improves maintainability
## Files Changed:
- src/Socket/messages-recv.ts:
* Fixed cache key logic to use stanzaId
* Import PlaceholderMessageData from Types
* Added detailed logging for cache operations
- src/Utils/process-message.ts:
* Import PlaceholderMessageData from Types
* Removed local CachedMessageData definition
- src/Types/Message.ts:
* Added shared PlaceholderMessageData type
* Added Long import for timestamp type
## Impact:
- ✅ Metadata preservation NOW WORKS (was completely broken)
- ✅ pushName will be preserved in CTWA messages
- ✅ participantAlt (LID) will be maintained in groups
- ✅ No more orphaned cache entries
- ✅ Type safety improved with shared definition
## Testing Note:
Issue #3 (missing test coverage) acknowledged but deferred to separate PR
to avoid blocking critical bugfix.
