There was a problem hiding this comment.
One correctness bug must be fixed before merge (see inline comment above).
Bug: startPreparationAsync in session-prepare.ts does not pass identityKiloUserId to the Durable Object's PreparationInput. The user-token path in executePreparationSteps (async-preparation.ts) is gated on input.identityKiloUserId being set, so user-token resolution is silently skipped on every autoInitiate=true session (the normal production fast path). All sessions on the async path fall back to the app bot token even when ENABLE_GITHUB_USER_TOKENS=true.
Fix: Add identityKiloUserId: ctx.userId to the startPreparationAsync call block in session-prepare.ts (mirroring what the sync prepare() call already does at line ~691).
A secondary non-blocking style issue: the double as-cast in getOctokitStatus (user-github-token-service.ts) should use flow-sensitive typing with a single narrowing cast instead.

Fixed both issues:

Refinery code review passed. All quality gates pass. Summary: The MVP commit-as-user implementation is well-structured and secure. The OAuth state is properly HMAC-signed with TTL, tokens are encrypted at rest with a dedicated key, the GDPR soft-delete is covered, and the feature is safely gated behind Minor observations (no changes required):
Both are minor and do not affect correctness or security. Safe to merge. |

Two env-var documentation issues that will cause silent failures or confuse local dev setup. No logic or security bugs found in the core implementation — the OAuth flow, encryption, GDPR handling, token refresh fallback, and feature gating all look correct.

Refinery Code Review — Changes Requested
Found three issues that need to be addressed before merging:
1. Dynamic import in Cloudflare Worker (critical)
File: services/git-token-service/src/user-github-token-service.ts, line 91
// ❌ Current
const { decryptWithSymmetricKey } = await import('@kilocode/encryption');
// ✅ Fix: use a static top-level import
import { decryptWithSymmetricKey } from '@kilocode/encryption';await import('@kilocode/encryption') is a dynamic import inside a Cloudflare Worker method body. Workers are bundled statically by Wrangler/esbuild — dynamic import() of workspace packages can fail at runtime or produce incomplete bundles. This must be converted to a static top-level import.
2. Dead expired_state type variant
File: apps/web/src/app/api/integrations/github/user-connect/callback/route.ts, line 15
'expired_state' is declared in the GitHubConnectError union but is never emitted. verifyOAuthState() returns null for both expired and tampered/invalid states, and the callback maps null → 'invalid_state' unconditionally. Either:
- Remove
'expired_state'from the union (dead code), or - Update
verifyOAuthStateto return a discriminated result{ valid: false; reason: 'expired' | 'invalid' }so the callback can emit the correct error to the UI.
3. Mocks in tests violate AGENTS.md
File: apps/web/src/app/api/integrations/github/user-connect/callback/route.test.ts
AGENTS.md: "Avoid mocks; they make tests complex and brittle, assert on the result instead or check the db to observe a side effect."
This test file mocks @/lib/config.server to inject the encryption key — this is avoidable by setting process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY = '...' in a beforeEach. The Octokit/oauth-methods mocks are harder to avoid for network calls, but the @/lib/config.server mock should be replaced with an env-var approach.

Refinery Code Review — Issues Remaining (Round 2)
Three issues from the previous review round (2026-05-20T08:37:59Z) remain unaddressed in the current HEAD. All three must be fixed before merge.
1. Dynamic import in Cloudflare Worker (critical — unchanged)
services/git-token-service/src/user-github-token-service.ts line 91 still has:
const { decryptWithSymmetricKey } = await import('@kilocode/encryption');This is a dynamic import inside a Cloudflare Worker method. Workers are bundled statically by Wrangler/esbuild — dynamic import() of workspace packages can fail at runtime or produce incomplete bundles. Convert it to a static top-level import:
import { decryptWithSymmetricKey } from '@kilocode/encryption';2. Dead expired_state type variant (unchanged)
apps/web/src/app/api/integrations/github/user-connect/callback/route.ts line 16: 'expired_state' is declared in the GitHubConnectError union but is never emitted. The callback always maps an invalid/expired/tampered state to 'invalid_state'. Either remove 'expired_state' from the union (simplest fix), or teach verifyOAuthState to return a discriminated result distinguishing expired vs invalid so the UI can show the right message.
3. jest.mock('@/lib/config.server') in tests (unchanged)
apps/web/src/app/api/integrations/github/user-connect/callback/route.test.ts line 39 still mocks @/lib/config.server to inject the encryption key. AGENTS.md: "Avoid mocks; they make tests complex and brittle." This specific mock is avoidable — replace it with process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY = '...' in a beforeEach (and restore in afterEach). The Octokit/oauth-methods mocks for network calls are acceptable as they cannot be avoided without a live GitHub API.

Unchanged from prior review: 'expired_state' is declared here but never emitted anywhere in this file. verifyOAuthState() returns null for both expired and tampered states, and the callback maps null → 'invalid_state' unconditionally.
Simplest fix: remove 'expired_state' from the union. Alternatively, return a discriminated result from verifyOAuthState so the callback can distinguish expired vs invalid and emit the correct error to the UI.

Unchanged from prior review: This jest.mock('@/lib/config.server') is avoidable. Replace it with direct env var assignment:
beforeEach(() => {
process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY = 'MTIzNDU2Nzg5MDEyMzQ1Njc4OTAxMjM0NTY3ODkwMTI=';
});
afterEach(() => {
delete process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY;
});This avoids mocking a module boundary just to set a config value. Per AGENTS.md: "Avoid mocks."

Refinery review — 3 issues remain unaddressed at HEAD (c1bf1f0)
All three issues flagged in the prior review cycle are still present. The branch must be fixed before merge.
1. Critical — Dynamic import in Cloudflare Worker
File: services/git-token-service/src/user-github-token-service.ts line 92
const { decryptWithSymmetricKey } = await import('@kilocode/encryption');Cloudflare Workers are statically bundled by Wrangler/esbuild. Dynamic import() of a workspace package inside a method body can fail at runtime because the module graph is resolved at bundle time.
Fix: Convert to a static top-level import:
import { decryptWithSymmetricKey } from '@kilocode/encryption';Then use it directly without the destructuring await import.
2. Dead type variant — 'expired_state' is never emitted
File: apps/web/src/app/api/integrations/github/user-connect/callback/route.ts line 17
'expired_state' is declared in the GitHubConnectError union but verifyOAuthState() returns null for both expired and tampered states, and the callback unconditionally maps null → 'invalid_state'. The 'expired_state' variant is dead code.
Fix (choose one):
- Remove
'expired_state'from the union (no behaviour change). - Update
verifyOAuthStateto return a discriminated result{ valid: false; reason: 'expired' | 'invalid' }so the correct error can be emitted.
3. Avoidable module mock — AGENTS.md: "Avoid mocks"
File: apps/web/src/app/api/integrations/github/user-connect/callback/route.test.ts line 40
Also: apps/web/src/routers/github-apps-router.test.ts line 12
jest.mock('@/lib/config.server', ...) exists solely to inject the encryption key. Replace with an env-var approach:
beforeAll(() => {
process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY = 'MTIzNDU2Nzg5MDEyMzQ1Njc4OTAxMjM0NTY3ODkwMTI=';
});
afterAll(() => {
delete process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY;
});Remove the jest.mock('@/lib/config.server', ...) block in both test files.

Critical — Dynamic import in Cloudflare Worker
Cloudflare Workers are statically bundled by Wrangler/esbuild. await import('@kilocode/encryption') inside a method body can fail at runtime because the module graph is resolved at bundle time, not at call time.
Fix: convert to a static top-level import:
import { decryptWithSymmetricKey } from '@kilocode/encryption';Then call decryptWithSymmetricKey(...) directly on line 93 without the destructured await import.

Dead type variant — 'expired_state' is never emitted
verifyOAuthState() returns null for both expired and tampered states, and the callback maps null → 'invalid_state' unconditionally. 'expired_state' is dead code in this union.
Fix: either remove it from the union, or update verifyOAuthState to return a discriminated result { valid: false; reason: 'expired' | 'invalid' } so the correct variant can be emitted.

Avoidable module mock — AGENTS.md: "Avoid mocks"
This mock exists solely to inject USER_GH_APP_TOKEN_ENCRYPTION_KEY. Replace with:
beforeAll(() => {
process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY = 'MTIzNDU2Nzg5MDEyMzQ1Njc4OTAxMjM0NTY3ODkwMTI=';
});
afterAll(() => { delete process.env.USER_GH_APP_TOKEN_ENCRYPTION_KEY; });Drop the jest.mock('@/lib/config.server', ...) block. The same fix is needed in github-apps-router.test.ts.
- Convert dynamic import of @kilocode/encryption to static top-level
import in user-github-token-service.ts (Cloudflare Workers require
static bundling)
- Remove dead 'expired_state' from GitHubConnectError union; verifyOAuthState
returns null for both expired and tampered states, both map to 'invalid_state'
- Replace jest.mock('@/lib/config.server') with process.env assignment in
beforeEach/afterEach; route now reads USER_GH_APP_TOKEN_ENCRYPTION_KEY via
getEnvVariable() at call time instead of module init
