Both handlers used shell-interpolated concat form "/configs/" + path which allows path traversal to escape the /configs bind mount. Switch to two-arg exec form: ["cat", "/configs", relPath] and ["rm", "-rf", "/configs", filePath] which bind the command to the configs volume regardless of path content.

Validate() scans: SELECT id, prefix, org_id FROM org_api_tokens (sql.NullString for org_id). Updated all mock expectations: - TestValidate_HappyPath: 3-column WillReturnRows - TestValidate_UnknownHashErrInvalid: 3-col regex, ErrNoRows - TestValidate_RevokedTokenNotAccepted: 3-col regex, ErrNoRows Also rewrote wsauth_middleware_org_id_test.go: - orgTokenValidateQueryV1 uses 3-column SELECT (no ::text cast) - Removed dead orgTokenOrgIDQuery secondary lookup - Removed redundant F1097 secondary lookup mock - Validate() now returns org_id inline — no follow-on DB lookup needed Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…I-005) KI-005 CRITICAL: terminal.go HandleConnect had zero CanCommunicate check. Any workspace could reach any other workspace's terminal by knowing the target's UUID (enumeration via canvas, logs, or delegation). Fix: when caller presents X-Workspace-ID header with a bearer token: 1. ValidateToken binds the token to the claimed workspace (prevents identity forgery via org-scoped token) 2. canCommunicateCheck(callerID, workspaceID) gates terminal access Self-access (callerID == workspaceID) always allowed — a workspace's own token reaches its own terminal without hierarchy check. Legacy access (no X-Workspace-ID header) passes through unchanged — WorkspaceAuth gates apply upstream on the WS-authenticated route. Added 5 tests: - TestKI005_SelfAccess_AlwaysAllowed - TestKI005_CanCommunicatePeer_Allowed - TestKI005_CanCommunicateNonPeer_Forbidden - TestKI005_TokenMismatch_Unauthorized - TestKI005_NoXWorkspaceIDHeader_LegacyAllowed Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Resolve conflicts: - wsauth_middleware_org_id_test.go: take 3-column org_id scan version - orgtoken/tokens_test.go: take 3-column org_id scan version Both our staged files and origin/main's files reflect the F1097 migration-036 org_id single-round-trip refactor; the only difference was the base version (stage 1) still had the pre-migration 2-query pattern. Take the post-migration version from stage 2. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
