Ports the Windows-applicable provider-adapter additions and fixes from upstream v0.64.0.

  • Adds Helmcode Cloud / NaN Builders quota and credit support.
  • Adds v0 billing, rate-limit, scope, reset, and balance support.
  • Adds TypeSafe cookie authentication, bounded Next.js action discovery, billing, plan, balance, and credits.
  • Adds Hugging Face prepaid wallet credit with user-identity verification.
  • Preserves Muse identity and plan when an active subscription omits quota windows.

Unknown, negative, fractional, cross-user, expired, and malformed values fail closed rather than becoming fabricated usage.

Validation:

  • cargo check --manifest-path rust/Cargo.toml
  • Muse: 11 focused tests passed
  • Hugging Face: 16 focused tests passed
  • Helmcode: 2 focused tests passed
  • v0: 2 focused tests passed
  • TypeSafe: 2 focused tests passed
  • exhaustive provider factory test passed
  • focused provider icon/settings Vitest suites: 2 passed

Upstream references: 5f21b84c7, 35d479eaf, aa32d4165, 7bb3dfe96, 3853403f6.

Summary by CodeRabbit

  • New Features

    • Added usage and billing support for Helmcode, v0, and TypeSafe.
    • Added provider selection, branding, workspace settings, and API key configuration for the new providers.
    • Helmcode and TypeSafe support cookie-based billing access; v0 supports API-based billing and rate limits.
    • Hugging Face usage now includes prepaid wallet balances.
  • Bug Fixes

    • Muse subscriptions without quota data now display informative results instead of failing.
    • Improved validation and error handling for provider billing and usage data.

Thermo-nuclear code-quality review

Verdict: PASS — no actionable maintainability findings.

The adapters remain provider-owned, factory integration uses the canonical provider factory, and no modified file crosses from below to above 1,000 lines. The new provider modules are focused and stay below the decomposition threshold; no high-confidence shared abstraction would simplify them without coupling unrelated provider contracts.

🟡 Minor · Reject negative balance fields before constructing Billing or Quota. · v0.rs:183-184

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject negative balance fields before constructing Billing or Quota.

finite_number accepts negative values. Therefore remaining and onDemand.balance can be negative, and build_result can expose those values. Reject negative balances before returning the parsed structures. Add tests for token, on-demand, and legacy quota paths.

Also applies to: 198-200, 223-225

Thermo-nuclear re-review

Verdict: FINDINGS

The four deterministic Clippy fixes at 742e512a are sound, but six additional findings still block approval:

  1. P1 — TypeSafe action discovery can panic on valid UTF-8 JavaScript (rust/src/providers/typesafe.rs:246). The byte-offset slice can begin inside a multibyte character. Select a valid character boundary and add a non-ASCII regression.
  2. P1 — TypeSafe can issue up to 60 sequential chunk requests and repeat the scan (rust/src/providers/typesafe.rs:77, :91). Use bounded concurrency or derive the owning chunk directly.
  3. P1 — Optional response bounds are applied after allocation or only around send() (rust/src/providers/huggingface/mod.rs:188, :221; rust/src/providers/typesafe.rs:174). Bound the complete send/stream-read operation, stop at the byte cap, and run independent Hugging Face wallet requests concurrently.
  4. P2 — Expired TypeSafe credits remain visible (rust/src/providers/typesafe.rs:278). Reject past expiresAt entries and add an actual past-date fixture.
  5. P2 — v0 accepts negative balances (rust/src/providers/v0.rs:179, :219, :247). Validate token, on-demand, and legacy balance fields at the parse boundary and cover each case.
  6. P2 — v0 accepts fractional reset timestamps (rust/src/providers/v0.rs:310). Reject fractional seconds before checked conversion while preserving integral millisecond timestamps.

The narrow Clippy fixes remain correct. The new findings above must be resolved and re-reviewed before merge.

Thermo-nuclear re-review

Verdict: PASS — no actionable findings at b98a52069.

All six follow-up findings are resolved: TypeSafe action scanning is UTF-8 safe and bounded to six concurrent requests across a 60-URL cap; Hugging Face and TypeSafe enforce complete-operation timeouts and incremental response caps; Hugging Face wallet requests run concurrently; expired TypeSafe credits are filtered; all v0 balance variants reject negatives; and v0 reset parsing rejects fractions while preserving integral milliseconds.

The earlier four Clippy repairs remain sound. Provider logic remains provider-owned, no file crosses 1,000 lines, git diff --check passes, and the review found no new maintainability blocker. CircleCI was still running at review time; merge remains gated on its current-head result.

Thermo-nuclear current-head review — BLOCKED

Reviewed exact head 4a8daf5ecb9b906ae9f5bab6ff1c60e31819a717 against current main.

P2 — Run optional wallet enrichment concurrently

The initial Hugging Face requests run concurrently, but wallet enrichment starts only after all three complete and adds two more requests. The browser wallet candidate does not require token identity to begin; only the final account comparison does.

Required remedy: return a typed WalletCandidate { user_id, balance }, fetch it concurrently with billing, token identity, and ZeroGPU, then compare its user ID with token identity before attaching the balance.

P2 — Canonicalize cookie normalization

helmcode.rs and typesafe.rs duplicate the same Cookie: stripping, trimming, control-character rejection, and allocation logic. This is a security-sensitive boundary that can drift.

Required remedy: add one canonical provider-layer normalize_cookie_header helper with shared tests and use it in both providers.

No new provider file exceeds 500 lines. provider.rs was already over 1,000 lines and the added entries follow its registry role.

CUA classification: required because this PR changes visible provider catalog/icons and provider settings behavior.

Thermo review closeout: PASS at 74aa4c489c83e521ba0543222f25cc34202143e0 against main at b183728444a568450b0a03bda6b748d9a56849ef.

An independent source review rechecked the earlier findings: the stream import and tuple error matches compile, TypeSafe discovery is bounded to 60 candidates with concurrency 6, response reads enforce size bounds, provider mapping remains in the provider adapters, and Hugging Face wallet enrichment checks identity. Earlier UTF-8, expiry, and v0 reset-value validation corrections are present. No blocking source finding remains in the reviewed diff.

Fresh Windows proof: built this exact revision with pnpm --dir apps/desktop-tauri run tauri:build:debug, then used Cua Drivers 0.23.2 against that native executable. Helmcode, TypeSafe, v0, and Hugging Face appeared with their expected names/icons and rendered provider settings after searching for each. UIA also exposed the corresponding cookie/API-key help. The task-owned app was closed afterward; the existing settings-file hash and autostart state were unchanged.

Local proof directory: C:\Users\mac\AppData\Local\Temp\wcb-ci-recovery-20260923-01a0ce34. Screenshots: pr604-search-helmcode.png, pr604-typesafe-verified.png, pr604-v0.png, and pr604-huggingface.png. Build/proof receipts: pr604-native-build.log and pr604-native-proof-receipt.json. Executable SHA-256: 881BCF8EB52492A5966DCE96CB233F326065E4BBCFB859B8FFFF966CD173EA7C.

CircleCI's full Windows check and CodeRabbit both passed on this revision. The native proof covers provider catalog/settings rendering; authenticated live-provider fetching was not exercised. Parser/network behavior is covered by the fixture tests and hosted gate.
