Filter validations (6 tests) + - Polling validations (4 tests) + - Multiple errors (1 test) + - maskSecrets (8 tests) + +## Learnings +- Bird CLI does NOT support PDF upload - X/Twitter renders PDFs poorly. Must convert PDF→PNG before upload. +- Bird's follower count lookup is available via `getUserByScreenNameGraphQL()` - returns full profile with `followersCount`. +- X/Twitter spam detection is REAL: identical content, high frequency, and bulk actions trigger blocks. Conservative rate limits (10-15/day, 10min gaps) are essential. +- Bun has built-in `bun:sqlite` module that's 3-6x faster than better-sqlite3 - perfect for this project. +- Manus API uses task-based async workflow: create task → poll status → download result. Expect 60-90s generation time. +- Bird uses undocumented GraphQL API with rotating query IDs - can break without notice. This is an accepted risk. +- X deprecated v1.1 media upload on March 31, 2025. Bird handles this internally via GraphQL. +- Best practice: Keep 30% activity manual to avoid bot detection. Start with warm-up period (1-3 weeks). +- Author caching strategy: Cache follower counts for 24h to reduce API calls and avoid rate limits on user lookups. +- Quality commands discovered: `pnpm run lint`, `pnpm test`, `pnpm run build` all available and working. +- Requirements phase: Primary user is internal developers (backend automation), not end users. No UI needed. +- Critical MVP priorities: P0 = core pipeline (poll, filter, generate, reply), P1 = error handling, P2 = optimizations. +- Dry-run mode is non-negotiable for safe testing before production deployment. +- Deduplication must be atomic: check + insert in single transaction to prevent race conditions. +- 5-minute reply window is hard constraint - drives all latency targets (Manus <120s, PNG conversion <5s). +- Reply text variation (5+ templates) is P0 requirement - identical text triggers spam detection immediately. +- Circuit breaker pattern essential for Manus failures - prevents wasting time on degraded service. +- Author cache hit rate >60% after warmup is key performance indicator - reduces API calls significantly. +- Design phase: Standalone application architecture chosen over integrated bird module for cleaner separation and independent deployment. +- Bird uses mixin architecture for composability - TwitterClient composes multiple mixins (search, posting, media, etc.). +- Bird error pattern: Return `{ success: boolean; error?: string; data?: T }` instead of throwing exceptions (except critical failures). +- Bird module system: ES modules with NodeNext resolution, all imports use `.js` extensions even for TypeScript files. +- Filter pipeline architecture: Multi-stage validation (content → deduplication → followers → rate limits) for clear separation and debuggability. +- Circuit breaker only for Manus: Bird has built-in retry logic, Manus is highest latency/failure risk (60-90s generation time). +- Database singleton pattern for rate_limits table: Single row (id=1) stores global rate limit state, prevents race conditions. +- Security: All DB queries must use parameterized queries (bun:sqlite supports), mask secrets in logs, .env in .gitignore. +- Performance budget breakdown: 70-120s typical, 300s max (5min), 90th percentile target <180s for full pipeline. +- Testing strategy: Unit tests for filters/config (90%+), integration tests with real SQLite in-memory, dry-run mode for end-to-end validation. +- Task planning: 47 total tasks across 4 phases (POC, Refactoring, Testing, Quality Gates) following POC-first workflow. +- POC phase focuses on working pipeline demonstration with shortcuts (hardcoded values, minimal validation, no tests). +- Phase 1 critical path: Project setup → Types → Config → Logger → Database → Poller → Filter → Generator → Responder → Main orchestrator → E2E validation. +- Quality checkpoints every 2-3 tasks prevent accumulation of type errors and lint issues. +- Phase 2 refactoring adds robustness: follower count filtering, rate limit enforcement, retry logic, circuit breaker, comprehensive error handling, graceful shutdown. +- Phase 3 testing is comprehensive per user request: unit tests (config, filters, templates, DB), integration tests (filter+DB, Manus API), E2E tests (full pipeline, real Twitter). +- E2E validation strategy: POC uses manual script with dry-run mode, Testing phase adds automated E2E with mocks plus optional real API tests when credentials available. +- Phase 4 quality gates: Biome+Oxlint linting, strict TypeScript, full test suite, README documentation, PR with passing CI. +- Dependency on Manus API: Must test real PDF generation in E2E validation (Task 1.23, 3.8) to verify integration works, not just that code compiles. +- Author cache seeding (Task 1.21) critical for startup performance - pre-populates 12 known influencers to avoid cold-start API calls. +- Circuit breaker state persisted in DB singleton row alongside rate limits - enables restart resilience without losing failure tracking. +- Dry-run mode testing non-negotiable for safe pre-production validation - all pipeline stages execute but skip actual Twitter posting. +- Manus API response fields may use snake_case or camelCase - handle both (taskId/task_id, outputUrl/output_url, etc.). +- Config validation uses process.exit(1) on failure for clear error messages before any other startup code runs. +- Bun's --eval flag syntax is `bun --eval` not `bun run --eval` - different from npm/yarn patterns. +- Bun types: Use @types/bun (not bun-types) in devDependencies, and "types": ["node", "bun"] in tsconfig.json (not "bun-types"). +- Bird dependency: Use file:.. reference (not workspace:*) since this is a standalone app in the same repo without pnpm workspaces configured. +- bun:sqlite uses synchronous API but wrapped in async interface for consistency with Database type definition. +- WAL mode enabled for better concurrent access (PRAGMA journal_mode = WAL). +- SQLite stores booleans as integers (0/1), need explicit conversion when reading. +- TwitterClient constructor expects `{ cookies: TwitterCookies }` object, not individual authToken/ct0 params. +- Bird's resolveCredentials returns `{ cookies: TwitterCookies, warnings: string[] }` - access tokens via result.cookies.authToken/ct0. +- Bird TweetData has optional authorId field - use author.username as fallback when authorId is not present. +- Language detection: Bird doesn't expose language directly in TweetData; rely on search query filter (lang:en) and default to 'en'. +- pdf-to-png-converter expects ArrayBufferLike, not Buffer or Uint8Array directly. Use pdf.buffer.slice() to extract the underlying ArrayBuffer. +- PNG is a lossless format - cannot directly reduce quality like JPEG. For size reduction, would need to re-render at lower viewport scale or convert to JPEG. +- Generator module orchestrates the full Manus -> PDF -> PNG pipeline with proper timeout handling and error logging at each stage. +- E2E validation script (`scripts/e2e-test.sh`) verifies full pipeline in dry-run mode. With dummy credentials, all components initialize and run correctly; auth errors are expected and properly handled. +- E2E validation shows 11 passing checks: orchestrator init, database init, poll loop, cycle execution, error handling, graceful shutdown, and database state verification. + +### Verification: Task 1.4 [VERIFY] Quality checkpoint +- Status: PASS +- Command: `bun run tsc --noEmit` (exit 0) +- Duration: <2s +- Result: No type errors found, no fixes needed + +### Verification: Task 1.7 [VERIFY] Quality checkpoint +- Status: PASS +- Command: `bun run tsc --noEmit` (exit 0) +- Duration: <2s +- Result: No type errors, code compiles cleanly after logger and database schema tasks + +### Verification: Task 1.10 [VERIFY] Quality checkpoint +- Status: PASS +- Command: `bun run tsc --noEmit` (exit 0) +- Duration: <2s +- Result: No type errors, code compiles cleanly after poller and filter pipeline tasks + +### Verification: Task 1.13 [VERIFY] Quality checkpoint +- Status: PASS +- Command: `bun run tsc --noEmit` (exit 0) +- Duration: <2s +- Result: No type errors, code compiles cleanly after Manus client and PDF converter tasks + +### Verification: Task 1.16 [VERIFY] Quality checkpoint +- Status: PASS +- Command: `bun run tsc --noEmit` (exit 0) +- Duration: <2s +- Result: No type errors, code compiles cleanly after generator and reply templates tasks + +### Verification: Task 1.19 [VERIFY] Quality checkpoint +- Status: PASS (after fixes) +- Command: `bun run tsc --noEmit` +- Initial: 3 type errors found +- Fixes applied: + 1. responder.ts line 59: Changed `source` to `cookieSource` in resolveCredentials options + 2. responder.ts lines 183, 190: Fixed TweetResult discriminated union handling (error only exists on failure branch) +- Commit: 3ee3635 +- Duration: <5s total +- Result: All type errors resolved, code compiles cleanly + +### Verification: Task 1.22 [VERIFY] Quality checkpoint +- Status: PASS (after fixes) +- Commands: `bun run tsc --noEmit`, `cat data/seed-authors.json | jq length` +- Initial: 1 type error found (TS6059 -
