✅ By-Wallet Endpoint — Event-Indexed, Paginated, Role-Aware (Issue #1 Progress)

Goal: Replace the stub RPC-based GET /api/jobs/by-wallet/:address with a fast, SQLite-backed implementation that reads from the local event indexer.

What was built:

src/indexer/db.ts — Added getJobsByWallet(address, page, limit):

• Queries events table for rows where data_json LIKE %address%
• Parses data_json as JSON and checks role fields strictly (client, freelancer, arbiter) — protects against false-positive LIKE matches on other string fields
• Groups events by contract_id using a Map — one distinct job per contract
• Each job summary captures: contract_id, role, milestone_count, latest_event_type, latest_ledger, latest_timestamp
• Applies page/limit pagination (1-based, safe clamping)
• Returns { jobs, total, page, limit }
• Also exported JobSummary and PaginatedJobs TypeScript interfaces

src/routes/jobs.ts — Replaced old by-wallet handler:

• Removed live RPC call (simulateTransaction on a hardcoded single contract)
• Now calls getJobsByWallet(address, page, limit) directly from SQLite — sub-millisecond reads
• Validates ?page and ?limit query params with clear 400 errors
• Response shape: { success: true, jobs: [...], total, page, limit }

__tests__/by-wallet.test.ts — 15 new tests:

• Returns empty when no events for address
• Role detection: client ✅ freelancer ✅ arbiter ✅
• Grouping: multiple events for same contract → single job entry
• Multi-contract: distinct jobs across C1/C2/C3
• False-positive guard: address in token field is NOT returned
• Pagination: page 1 of 2, page 2 of 2, last partial page, page beyond total
• HTTP integration (supertest): response shape, empty address, pagination params, job field types

Verification:

• npx tsc --noEmit → ✅ Zero errors
• npm test → ✅ 19/19 tests pass (3 suites: indexer, jobs, by-wallet)
• npm run build → ✅ Clean
• Commit: 9bd8508 — feat: wire indexer into by-wallet endpoint with pagination and role detection
• Pushed to GitHub, CI running

🎯 Next Steps (Updated):

• Confirm CI green on 9bd8508, then close issue #1 with proper comment
• Wire remaining contract functions (fund, deliver, approve, dispute, resolve) to frontend
• Add support for multiple jobs in contract
• Audit contract for security issues
• Deploy and sync generated issues to GitHub using the sync.js script

✅ Collaborator Project Roadmap & Issue Generator (1,000 Issues)

Goal: Break the next major phases of Milesto down into 10 distinct phrases, each comprising 100 independent, well-labelled issues (1,000 issues total) to facilitate parallel development with collaborators, including a tool to preview and sync them.

What was built:

milesto-roadmap/generate.js:

• Programmatic Node.js generator.
• Splits development into 10 phrases across core domains: contract safety, advanced features, API security, indexer performance, wallet integrations, component libraries, admin/arbitrator portals, financial math, notification triggers, and monitoring/telemetry.
• Compiles exactly 100 independent issues per phrase, each referencing the target repository, validation check, implementation steps, testing guidelines, and difficulty labels.
• Outputs structured JSON issue templates into local directories under milesto-roadmap/issues/.

milesto-roadmap/sync.js:

• Interactive CLI import utility.
• Supports Dry-Run Mode (logs exact gh CLI commands to execute) and Live Mode (creates issues via local authenticated gh CLI credentials).
• Automatically parses and resolves the owner/repo mapping for the target packages (escrow-contract, escrow-backend, escrow-frontend) by checking git remote urls.

Verification:

• Ran node generate.js → successfully generated 10 folders, each containing exactly 100 issue JSON configurations (1,000 total).
• Tested echo "1" | node sync.js → successfully verified dry-run CLI command formatting and github remote mapping resolver.
