Full details: Out of Scope Changes checkExplanation The PR includes unrelated frontend CI and dependency changes, AST formatting, EVM test changes, integration-test edits, TypeScript configuration changes, and a global lodash override. These changes are not required for issue Resolution Move unrelated frontend, EVM, test-formatting, and dependency changes into separate pull requests, or provide linked requirements that justify them. Keep this pull request focused on the Discord and Slack bot implementation and its documentation. Full details: Docstring CoverageExplanation Docstring coverage is 34.78% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 23 functions across 10 files. (3 skipped: 3 unsupported.)

Inline comments:
In `@backend/src/services/botNotificationService.ts`:
- Around line 178-180: Update PactumBotWorker.pollDatabase so created-event
payloads include amount, currency, dueDate, and template queried from the
commitment source before notification rendering; preserve the existing
notification fields and ensure Discord and Slack receive the populated values
instead of fallback placeholders.
In `@backend/src/workers/discordBot.ts`:
- Around line 259-276: Use a single canonical creation-event identity across the
index and outcome query paths so duplicate Created notifications cannot be
emitted. Update the event-key construction around processedEvents and outcomeKey
to reuse the same commitment, outcome, and timestamp components, including
null/undefined pending outcomes, rather than comparing an index-based key with
an outcome-based key.
- Around line 216-238: The event-processing flow around broadcastNotification
must only commit an outcome after delivery succeeds. Make broadcastNotification
return whether any destination accepted the notification; when it reports
failure, stop the ordered scan before adding eventKey, incrementing
newEventsCount, or advancing lastPolledTime, so the same event can be retried.
Add a regression test covering failed delivery followed by a successful retry.
- Around line 208-211: Separate the polling state for the commitment_outcomes
and commitment_index streams instead of sharing lastPolledTime. Update each
source query to paginate with a stable composite cursor using its timestamp and
deterministic secondary key, preserving all rows sharing a timestamp. Advance
each stream’s cursor only after that source’s scan completes successfully.
In `@docs/discord-bot.md`:
- Around line 61-64: Update the Discord permissions list in the PactumBotWorker
setup documentation by removing the Read Message History permission, while
retaining Send Messages, Embed Links, and View Channels.
- Line 19: Update PactumBotWorker.pollDatabase and its startup flow to persist
and reload lastPolledTime as a durable high-water mark before claiming
persistent polling state; ensure the checkpoint survives restarts and prevents
missing older events, or remove the “persists last-polled state” claim from the
documentation if persistence is not implemented.

Why This PR Exists
DAOs, guilds, and organizations use Discord or Slack as their primary communication hubs. Previously, there was no automated mechanism to track member commitments in real-time without repeatedly checking the web dashboard. This PR introduces
pactum-bot, a dedicated backend worker and notification service that listens to the on-chain indexer database and broadcasts rich, real-time status updates (Created, Fulfilled, Late, Breached, Disputed) to Discord and Slack channels.What Was Wrong
What This PR Does
backend/src/services/botNotificationService.ts) — Implemented rich Discord Embeds and Slack Block Kit payload builders with custom status color-coding (Created:#3498DB, Fulfilled:#2ECC71, Late:#F1C40F, Breached:#992D22, Disputed:#E74C3C), address shortening (GABC...1234), amount formatting, and dashboard deep links.backend/src/workers/discordBot.ts) — Built thePactumBotWorkerservice supporting both Discord Gateway Bot Client (discord.js) and lightweight incoming webhooks (Discord & Slack) with database polling, event deduplication, and graceful shutdown lifecycle handlers.backend/package.json) — Addeddiscord.jslibrary along with npm runner scripts (npm run bot,npm run pactum-bot,npm run dev:bot).backend/.env.example) — Added environment variable templates forDISCORD_BOT_TOKEN,DISCORD_CHANNEL_ID,DISCORD_WEBHOOK_URL,SLACK_WEBHOOK_URL, andBOT_POLL_INTERVAL_MS.docs/discord-bot.md,README.md) — Documented step-by-step instructions on inviting the bot to Discord servers, setting up OAuth2 permissions, creating webhooks, and running the worker in production.backend/src/workers/discordBot.test.ts) — Added unit and integration tests covering address shortening, amount formatting, event classification, Discord embed generation, Slack block generation, and database deduplication.Security & Production Deployment Notes
