Summary

This PR addresses four issues from the second-wave repository audit, all assigned to @samjay8 as part of the Stellar Wave Program's 8th wave. Each solution is well-scoped to its respective issue and CI passes on all individual branches.

Closes #1253 · Closes #1269 · Closes #1273 · Closes #1286

Issue #1253 — Frontend bundle-size gate

Labels: enhancement frontend infra Stellar Wave

Problem: The contracts job enforced a hard 200 KB WASM size budget, but there was no equivalent gate for the Next.js frontend bundle — no size-limit, no @next/bundle-analyzer, no reporting of any kind.

Solution: Added frontend/scripts/check-bundle-size.sh — a bash script that calculates the total gzipped size of all .js files in .next/static and fails CI if the total exceeds a configurable budget (default: 600 KB). Wired into .github/workflows/ci.yml as a step after next build.

Files changed:

  • .github/workflows/ci.yml — added bundle-size check step
  • frontend/scripts/check-bundle-size.sh — new script (33 lines)

Issue #1269 — Legacy indexer service removal

Labels: backend refactor Stellar Wave

Problem: SorobanIndexerService (soroban-indexer.service.ts) documented itself as racing with SorobanEventWorker on the same Stream/StreamEvent tables. While it was dead code in production (never imported in index.ts), its file, tests, and architecture doc references remained, creating confusion.

Solution: Deleted the legacy service and its tests entirely. Updated docs/ARCHITECTURE.md to remove the "Three files with overlapping names" section and simplify the indexer ownership table to reflect that only SorobanEventWorker + indexerService.ts (control-plane) remain.

Files changed:

  • backend/src/services/soroban-indexer.service.ts — deleted (60 lines)
  • backend/tests/soroban-indexer.test.ts — deleted (82 lines)
  • docs/ARCHITECTURE.md — updated indexer ownership section

Issue #1273 — Wire Zod schema into createStream validation

Labels: backend refactor Stellar Wave

Problem: A Zod validation schema (createStreamSchema in stream.validator.ts) already existed with an MAX_I128 upper-bound check on ratePerSecond, but was never imported anywhere. The createStream controller used weaker manual parsing (parseRequiredBigIntField, StreamValidationError) that omitted this upper-bound check.

Solution: Replaced ~70 lines of manual validation (custom error class, parseRequiredBigIntField helper, individual field checks) with a single createStreamSchema.safeParse(req.body) call. This adds the MAX_I128 check and produces structured Zod error details. Updated test assertions to match the new error: 'Validation error' response format.

Files changed:

  • backend/src/controllers/stream.controller.ts — replaced manual validation with Zod schema
  • backend/tests/stream.controller.test.ts — updated assertions for new error format

Issue #1286 — Stream-details action handler tests

Labels: frontend testing Stellar Wave

Problem: None of the action handlers (handleWithdraw, handleTopUp, handlePause, handleResume, handleCancel) or the live-claimable interval logic in stream-details-content.tsx had test coverage.

Solution: Added 376 lines of comprehensive tests covering:

  • handleWithdraw — success toast, error toast, disabled button when claimable is zero
  • handleTopUp — success toast, error toast, empty-amount guard
  • handlePause — success toast, error toast, correct Soroban call args
  • handleResume — success toast, error toast, correct Soroban call args
  • handleCancel — modal flow entry, error path
  • Live-claimable interval — pulsing dot indicator, paused-state display

Files changed:

  • frontend/src/app/streams/[id]/__tests__/stream-details-content.test.tsx — +376 lines of handler tests

Verification

✅ CI passes on all 4 individual branches (PR Test Gate, CI, Security Checks — all success)
✅ All changes cherry-pick cleanly onto upstream/main with no conflicts
✅ No unrelated changes included — each fix is precisely scoped to its issue

d329b8e 
…rypt#1269, LabsCrypt#1273, LabsCrypt#1286)

Closes LabsCrypt#1253, LabsCrypt#1269, LabsCrypt#1273, LabsCrypt#1286

Add a gzip-based bundle-size budget check to CI that fails when the
Next.js frontend JS exceeds 600 KB gzipped. The check is wired into the
CI workflow after `next build` and uses a configurable budget via
FRONTEND_BUNDLE_BUDGET_BYTES env var.

Remove the deprecated `SorobanIndexerService` and its tests. This service
documented itself as racing with `SorobanEventWorker` on the same
Stream/StreamEvent tables (issue LabsCrypt#801). It was dead code — never imported
in the production startup path — but its presence was confusing and the
architecture docs still referenced it.

Replace the weaker manual `parseRequiredBigIntField` / `StreamValidationError`
parsing in `createStream` with the existing `createStreamSchema` Zod
validator that was already defined in `stream.validator.ts` but never used.
This adds the MAX_I128 upper-bound check on ratePerSecond that the manual
parsing omitted.

Add comprehensive tests for all 5 action handlers (handleWithdraw,
handleTopUp, handlePause, handleResume, handleCancel) plus the
live-claimable interval logic. Each handler has success-path and
error-path coverage, and the live-claimable display is verified for both
active and paused states.

fix(frontend): remove useMemo that React Compiler cannot preserve
48a8405 
The react-hooks/preserve-manual-memoization ESLint rule (React Compiler
in eslint-config-next 16) flags the useMemo wrapping a BigInt conversion
because the compiler cannot preserve memoization over BigInt values.
Replace with a plain ternary expression since the computation is trivial
and does not benefit from manual memoization.

fix(tests): resolve 6 failing stream-details-content tests
9316aaf 
- Wire vi.mock("@/lib/soroban") to hoisted mock functions instead of
  creating separate vi.fn() instances, so component actions use the same
  spies the tests assert on
- Use getAllByText for live claimable test since LiveValue renders an
  sr-only span with matching text
- Mock useStreamingAmount to return 0 for the disabled-withdraw test
  so liveClaimable is actually zero

Closes LabsCrypt#1286

fix(security): override mysql2 to patched version >=3.22.0
32767e8 
Adds npm override for mysql2 transitive dependency pulled in by prisma.
The vulnerable mysql2@3.15.3 had a high-severity auth downgrade CVE
(GHSA-3f6p-5ww8-9rcr). This forces the patched version without
downgrading prisma.
