Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds externally authenticated session APIs and credential lifecycle flows, but the successful wait response can return assistant text without the secret-redaction protection used elsewhere; unresolved credential revocation, error-handling, and other session behavior issues add further security and reliability risk, so the PR is not merge-ready until the highest-impact paths are fixed or explicitly accepted.

GlobalSecretsStore decryption path when the key is available and the empty-set
behavior when there are no changes.
In `@packages/control-plane/src/session/event-repository.ts`:

There was a problem hiding this comment.
This adds a substantial new surface, but the implementation is not ready to merge under a strict maintainability bar. The main blockers are structural rather than cosmetic: session creation introduces a permanent multi-store saga instead of leaning on deterministic identity and the existing idempotent bootstrap boundary; the event journal stores unbounded full revisions and has a secret-redaction boundary that can fail open; external prompt orchestration duplicates the canonical path and already diverges from it; and credential lifecycle operations can strand live bearer tokens. The list and follow-up contracts also expose concrete incompleteness at their boundaries.
No production file crosses the 1,000-line threshold in this PR. The concern is that complexity has been distributed across new route/store/schema layers without deleting enough concepts. Please address the inline blockers and consolidate session bootstrap, prompt dispatch, credential rotation/revocation, and external contract policy into their canonical owners before merging.

Summary
PR #1683: feat: add CLI and local MCP session management by @ColeMurray adds the CLI/MCP client, revocable device credentials, repository-less external session APIs, and a durable event journal. The implementation is extensive and well tested, but several security-boundary and correctness defects need to be fixed before merge.
Change size: 97 files, +11,097 / -242.
Critical Issues
- [Security]
packages/control-plane/src/routes/external-sessions.ts:346- Event redaction uses only current global-secret values. Rotated/deleted secrets and credentials injected from sandbox/MCP sources can be returned in free-form journaled tool output. See inline comment. - [Authentication]
packages/control-plane/src/router.ts:710-external-userroutes also accept a signed browser-session request because service authentication runs before CLI bearer authentication and only the principal kind is enforced. See inline comment. - [Correctness]
packages/control-plane/src/routes/cli-auth.ts:38- The advertised one-second polling cadence exhausts the 60-request sustained quota after about one minute despite a ten-minute authorization lifetime. See inline comment. - [API Correctness]
packages/shared/src/types/external-session-api.ts:47- Enabled models without reasoning controls cannot satisfy the required create schema. See inline comment. - [API Correctness]
packages/control-plane/src/routes/external-sessions.ts:258- Listings reporthasMorebut expose no continuation input, making sessions after the first 50 unreachable. See inline comment. - [Data Integrity]
terraform/d1/migrations/0073_external_session_create_operations.sql:2- New restricting user foreign keys are absent from canonical-user merge handling, causing merges to roll back for users with CLI auth or external-create records. See inline comment. - [Concurrency]
packages/control-plane/src/session/http/handlers/session-init.handler.ts:231- Concurrent bootstrap retries can both observe an uninitialized runtime and make an identical retry fail with a uniqueness error. See inline comment. - [Correctness]
packages/cli/src/config-store.ts:79- Reserved object-property context names such as__proto__corrupt metadata handling and orphan credentials. See inline comment.
Suggestions
- [Resource Management]
packages/cli/src/operations.ts:143andpackages/cli/src/cli.ts:307- Remove abort listeners when each polling sleep resolves; otherwise long waits accumulate listeners and trigger warnings. - [Recovery]
packages/cli/src/config-store.ts:133- Allow logout/status recovery when local credential material has already disappeared, so stale context metadata can still be removed. - [Abuse Resistance]
packages/control-plane/src/routes/cli-auth.ts:84- Enforce the IP limit before writing attacker-controlled per-secret counters; otherwise random secrets continue growing the D1 rate-limit table after the IP is blocked.
Nitpicks
None.
Positive Feedback
- The event mutation and change-journal writes are transactionally coupled, and the checkpoint/cursor tests cover updates, tombstones, renames, and pinned snapshots well.
- Credential storage separates metadata from secret material and includes careful rollback behavior for rotation and deletion failures.
- Public runtime error projection and schema validation are consistently bounded and typed.
Questions
None.
Verification
npm test -w @open-inspect/shared: all 815 tests passed.- Focused control-plane tests for device authorization, event projection, and bootstrap: all 25 tests passed.
git diff --check: passed.- The CLI run reached 45 passing tests, but two suites could not load because the current checkout does not have the newly declared
openand MCP SDK dependencies installed; this was not treated as a PR defect.
Verdict
Request Changes: the authentication bypass, secret-projection exposure, and functional/data-integrity regressions are blocking.
Terraform Validation Results
Pushed by: @open-inspect[bot], Action: |
|
Addressed the requested structural blockers in c166c4d. The external create saga and operation migration were deleted in favor of deterministic HMAC identity plus an atomically reserved request fingerprint; prompt admission/dispatch is canonical; event history is immutable but bounded by 24h, 50k revisions, and 16 MiB with explicit checkpoint expiry and allowlisted output; list pagination is end-to-end; and credential replacement/logout now use durable device-capability and bearer revocation recovery across restarts. Also fixed CLI-only auth provenance, poll quota, user merge references, context-name safety, native keyring fallback, and bootstrap races. Local validation: shared 816, CLI 101, control-plane unit 3,470, integration 1,111, web 1,428; lint, typecheck, production build, and diff checks pass. Terraform tooling is unavailable locally, so the pushed commit relies on the PR Terraform validation check for that layer. |

semantics when pruneChanges rotates cursor_scope: classify a previously valid
cursor invalidated by that rotation as EventFeedCheckpointExpiredError rather

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not use TextDecoder for binary signature checks.
new TextDecoder() decodes UTF-8 and replaces or merges invalid sequences, so the decoded string does not map one character per byte. WebP bytes 4..7 hold the little-endian file size. When those bytes form a valid multi-byte sequence, the decoder emits fewer characters and all later indices shift.
For a 47298-byte WebP, bytes 4..5 are C2 B8, a valid two-byte sequence. The decoded string becomes RIFF + one character + two NULs, WEBP starts at index 7, and signature.slice(8, 12) returns "EBP". The file is then rejected with "Attachment is not PNG, JPEG, WebP, or GIF". Compare bytes instead.

Persist the active credential for retry before local deletion.
When remote revocation fails transiently, retain the active credential in a pending revocation record. removeActiveContext() deletes it before logout() attempts revocation, so a copied bearer credential can remain usable until expiry.

Add a delay before retrying an expired checkpoint.
The expired branch resets checkpoint and calls continue. This skips the await this.sleep(interval, ...) at the end of the loop body. If the service keeps returning an expired error for the full-snapshot read (after === undefined), followEvents issues requests back-to-back with no delay until the deadline expires. Every other retry path in this loop sleeps first.
Sleep once before the retry, or limit the reset to a single attempt per snapshot read.

checkpoint = undefined;

Skip credential redaction for unauthenticated external requests.
For an external-user route, authentication failures reach withExternalErrorContract. With REPO_SECRETS_ENCRYPTION_KEY set, it performs unscoped queries across all managed secrets, MCP credentials, SCM tokens, provider credentials, and their histories, then decrypts the returned rows. The handler rate limiters run only after authentication succeeds. An unauthenticated caller can therefore force installation-wide database scans and bulk decryption on every request. Run this redaction only after authentication, and use an appropriately scoped or shared redaction set for authenticated responses.

A decryption failure turns every external error response into an unhandled exception.
decryptProviderAccountPayload at Line 1177 and decryptToken at Lines 1155-1156 are not wrapped in error handling. finalize is awaited at Lines 1018, 1042, 1080, and 1096, and none of those calls sit inside a try block. If one stored credential fails to decrypt, for example after key rotation or with an unexpected credential_schema_version, the rejection escapes handleRequest. Every error response on every external-user route then fails, and the CORS and trace headers added by withCorsAndTraceHeaders are lost.
The MCP branch at Lines 1141-1143 has a related defect: the catch calls JSON.parse(encrypted_env) on the raw ciphertext, which throws again and escapes the same way.
Make redaction-set construction non-fatal. Log the failure and continue with the values that decrypted.

Both redaction helpers assume refresh_token_encrypted is never NULL. The two code paths read the same user_scm_tokens and scm_credential_redaction_history columns, type them as string, and pass each value straight to decryptToken. SCM refresh tokens are commonly stored as NULL. One NULL row makes the call throw, which breaks the external events feed and the external error contract.

Apply or reject a cursor when limit is absent.
If a client sends ?cursor=... without limit, Line 137 ignores the cursor and returns the complete first listing. This restarts pagination and can return duplicate artifacts. Parse the cursor before this branch. Then either use a default page limit or return 400 when cursor has no limit.
