feat(whatsapp): add read receipt (blue ticks) support

[ed1y]

Summary

Automatically mark incoming WhatsApp messages as read (blue ticks) when WHATSAPP_MARK_READ=true is set. Opt-in — disabled by default for privacy.

Changes

scripts/whatsapp-bridge/bridge.js

• Added WHATSAPP_MARK_READ env var (default: false — opt-in, not opt-out)
• Added parseEnvBool() helper for consistent env var parsing
• Batch readMessages instead of per-message API calls (single call per message batch)
• sendPresenceUpdate('available') before batch read for reliable delivery on bot accounts
• Skip own messages (fromMe), broadcast lists, and groups
• Validate msg.key and remoteJid before any API calls
• Separate try/catch for sendPresenceUpdate and readMessages (presence failure doesn't block read)
• Logging: [blue-tick] Marked N message(s) as read

scripts/whatsapp-bridge/__tests__/bridge-blue-tick.test.js (new)

• 23 unit tests: parseEnvBool (11 cases), message filtering (8 cases), batch collection (4 cases)

How to Test

1. Set WHATSAPP_MARK_READ=true in environment
2. Send a message to the bot from another WhatsApp account
3. Verify the message shows blue ticks (read receipt) on the sender's phone
4. Set WHATSAPP_MARK_READ=false or unset — verify no blue ticks are sent

Closes #6539

Competing PRs for the same feature (WhatsApp read receipts): #9672, #13185, #8690. Related issues: #6539, #6055. Maintainers should pick one implementation and close the rest.

Thanks for tackling WhatsApp read receipts — the premise still exists on current main: the Baileys bridge’s messages.upsert handler processes incoming messages in scripts/whatsapp-bridge/bridge.js:259-467, and scoped search found no sock.readMessages path for that bridge.

Problems

• The diff queues messagesToRead before the existing processing gates. The PR diff populates it right after msg.key validation, while current main only rejects self-chat non-self traffic and allowlist mismatches later at scripts/whatsapp-bridge/bridge.js:312-334. With the flag enabled, rejected direct messages could still get blue ticks.
• The new WHATSAPP_MARK_READ flag is a behavioral setting. The project rubric says these should live in config.yaml and only be bridged internally if needed (AGENTS.md:102-106); the current WhatsApp config section is at hermes_cli/config.py:1972-1978.
• The PR body mentions a new scripts/whatsapp-bridge/__tests__/bridge-blue-tick.test.js, but GitHub reports only scripts/whatsapp-bridge/bridge.js changed.

Suggested changes

• Collect/read only messages that pass the same mode and allowlist checks as processed messages.
• Add the config.yaml setting and pass it to the bridge from gateway/platforms/whatsapp.py.
• Add tests for missing keys, fromMe, groups/broadcasts, allowlist rejection, empty batches, and batch reads.

This was generated by AI during triage.

Duplicate of #8690 — same WhatsApp read-receipt (blue tick) feature (#6539). This is a saturated competing-PR cluster; the earliest open implementation is #8690 (other open siblings: #9672, #13185). This PR adds a cleaner opt-in WHATSAPP_MARK_READ env + batched readMessages, but the underlying feature is the same — a maintainer should pick one from the cluster.

Thanks for the opt-in, batched implementation. The Baileys bridge on current main still lacks a readMessages path, so the feature remains useful, but this version needs rework against the current handler.

Problems

• scripts/whatsapp-bridge/bridge.js collects a receipt key before the current self-chat and allowlist gates (bridge.js:625-647). The submitted messagesToRead.push(...) can therefore acknowledge a foreign DM that the bridge deliberately rejects.
• The PR adds WHATSAPP_MARK_READ as a user-facing behavior flag. The established path is config.yaml → plugins/platforms/whatsapp/adapter.py::_apply_yaml_config (adapter.py:1712-1743) → bridge subprocess environment (adapter.py:622-652); the project rubric requires behavioral settings to use config.yaml.
• GitHub reports only scripts/whatsapp-bridge/bridge.js changed, so the tests claimed in the PR body are not present.

Suggested changes

• Collect receipt keys only after the same admission gates used for inbound delivery.
• Wire a default-false whatsapp.mark_read config setting through the existing adapter bridge.
• Add focused pure-helper tests for eligibility and one batched readMessages call.

This queues the receipt before the handler's self-chat and allowlist gates. A foreign DM rejected later by the current bridge policy would still receive a blue tick; collect this key only after the message has passed those admission checks.
